    2007-10-01

    Adult science illiteracy is widespread. This is concerning for astrobiology, or indeed any other area of science in the communication of science to public audiences. Where and how does this scientific illiteracy arise in the journey to adulthood? Two astrobiology education projects have hinted that science illiteracy may begin in high school. This relationship between high school science education and the public understanding of science is poorly understood. Do adults forget their science education, or did they never grasp it in the first place? A 2003 science education project raised these questions when 24 16-year-olds from 10 Sydney high schools were brought into contact with real science. The unexpected results suggested that even good high school science students have a poor understanding of how science is really undertaken in the field and in the laboratory. This concept is being further tested in a new high school science education project, aimed at the same age group, using authentic astrobiology cutting-edge data, NASA Learning Technologies tools, a purpose-built research Information and Communication Technology-aided learning facility and a collaboration that spans three continents. In addition, a first year university class will be tested for evidence of science illiteracy immediately after high school among non-science oriented but well-educated students.

    Astrobiology is the study of the origins, evolution and distribution of life in the universe. It provides a biological perspective to many areas of NASA research, linking such endeavors as the search for habitable planets beyond our solar system, exploration missions to Mars and Europa, and efforts to understand the origin and early evolution of life. Astrobiology addresses three fundamental questions: How does life begin and develop? Does life exist elsewhere in the universe What is the future of life on Earth and beyond? This talk will address our concepts about the definition of life, how life might have begun, and how our blaspheme and planet have co-evolved for billions of years. The talk will explore how the perspectives gained from interdisciplinary research in the biological, geological and space sciences will prepare us to search for habitable environments and blasphemes elsewhere in the Universe.

    2011-12-01

    The Astrobiology Graduate Conference (AbGradCon) is an extremely successful annual meeting of early career researchers and educators involved and interested in the field of astrobiology. The conference has been held eight times in various locations, each time organized by a different group of students. The primary objective of AbGradCon is to stimulate the future of astrobiology research by bringing together graduate students and early post-doctoral fellows in order to create and strengthen interdisciplinary and international networks of early-career astrobiologists who will lead such research in the years to come. The conference is unique in that it is a student-led meeting, from the organization to the presentations. AbGradCon strives to remove the "pressures" of typical scientific meetings by providing a relaxed atmosphere in which presentations and round-table discussions are fostered along with numerous social activities. The success of previous AbGradCons can be attributed to the sheer enthusiasm of the participants for astrobiology, and to the spirit and format of the conference, which is outlined in a charter written by past conference organizers and participants. Because it is organized and attended by only graduate students and early career astrobiologists, AbGradCon is an ideal venue for the next generation of early career astrobiologists to form bonds, share ideas, and discuss the issues that will shape the future of the field.

    Extrasolar Planet Transit and The Light Curve of a Variable Star are some titles of high school student projects entered in the Hawaii State Science Fair. These students were mentored by teachers who participated in the UH Institute for Astronomy Toward Other Planetary Systems summer program under the direction of professor Karen J. Meech. After attending several 3-week TOPS NSF workshops from 1999, these teachers in 2003 were trained to do observing plans to obtain telescope images, use image processing software MIRA for photometry, and produce light curves of variable stars and extrasolar planet transits. Others used the software Astrometrica to do astrometry of Kuiper Belt Objects. Using Compaq laptop computers on long term loan, our teachers mentored their students for astronomy projects during the 2003-2004 school year with the assistance of IfA astronomers and graduate students. Observing plans for images from the 31 inch Lowell Telescope in Arizona and the 2.2 meter UH telescope at Mauna Kea Observatory were followed. Students had to learn about variables such as exposure time, magnitude, frequency requirements, and ephemeris. The many iterations were time consuming and demanded patience and perseverance. Poor weather conditions exposed the students to the realities of astronomy research, so they experienced the highs of successful projects. Future projects will be related to the UH NAI team research using the 2.0 meter Faulkes Telescope located on Haleakala on island of Maui. The TOPS program is funded by National Science Foundation.

  8. Engaging in Science through Astrobiology Outreach

    2011-12-01

    There has been a steady decline in the number of Australian students studying science at the senior high school level. By the time students reach this point in their education, when they can choose whether or not to continue to study science, many have already decided that science is not for them. It is possible that students in the junior high school years may be gaining a false view of the world of science due to the disparity between the way that science is portrayed in schools and "real" science. A study is being undertaken to explore whether engaging in real science through outreach activities may increase students' understanding of the nature and processes of science, and whether such activities may heighten students' interest in science and potentially lead to an increase in the number of students studying science at the tertiary level. The study examines three astrobiology-related outreach programs, two in Australia and one in the US. The features of the programs are described and results from the Australian research carried out to date are presented.

  9. Astrobiology as an alternative integrated science curriculum for higher education

    Geller, Harold A.

    Many schools now offer an integrated science course to give students a taste of all of the sciences. These courses are types of survey courses that do not demonstrate the interdependencies among the various science disciplines. Students are exposed to each of the science disciplines individually. Astrobiology, as a multidisciplinary science requiring the skills of a physicist, chemist, geologist and biologist can be offered as a new paradigm in the teaching of science for non-science majors. A curriculum for a full-year course in astrobiology based upon sound content and pedagogy is presented.

    If we believe life to be a cosmic imperative, the understanding of life processes becomes a universal aspect of cosmology. How does life fit into our understanding of the universe. As a compliment to NASA's `Origins' Program we are developing a new venture to embark on one of the great scientific questions of our time, our origins, evolution and our destiny. NASA already deals with a number of related biological questions. We are introducing a new unifying approach to biology within the NASA... Astrobiology. Astrobiology is the study of the chemistry, physics and adaptations that influence the origin, evolution and destiny of life. We intent to raise the conscious level relating relevant biological questions to the formation and development of the universe through space missions and research programs. By linking certain aspects of exobiology, ecology, gravitational biology, and adding efforts in molecular biology, evolutionary biology, and planetary biology and joining this to Astronomy and planetology, we seek a deeper understanding of where the living process fits in to our cosmological theories. We do this through laboratory experiments, space observations, computer modeling, missions and discovery of what appear to be extreme conditions for us, but conditions in which life thrives. NASA has formed an international `virtual' Astrobiology Institute as a nucleus to initiate this consolidating idea. NASA's technology will play a major role in this endeavor.

    The Space Science and Astrobiology Division's researchers are pursuing investigations in a variety of fields, including exoplanets, planetary science, astrobiology, and astrophysics. In addition division personnel support a wide variety of NASA missions. With a wide variety of interesting research going on, distributed among the three branches in at least 5 buildings, it can be difficult to stay abreast of what one's fellow researchers are doing. Our goal in organizing this symposium is to facilitate communication and collaboration among the scientist within the division and to give center management and other ARC researchers and Engineers an opportunity to see what scientific missions work is being done in the division.

  13. Astrobiology in culture: the search for extraterrestrial life as "science".

    PubMed

    Billings, Linda

    2012-10-01

    This analysis examines the social construction of authority, credibility, and legitimacy for exobiology/astrobiology and, in comparison, the search for extraterrestrial intelligence (SETI), considering English-language conceptions of these endeavors in scientific culture and popular culture primarily in the United States. The questions that define astrobiology as a scientific endeavor are multidisciplinary in nature, and this endeavor is broadly appealing to public audiences as well as to the scientific community. Thus, it is useful to examine astrobiology in culture-in scientific culture, official culture, and popular culture. A researcher may explore science in culture, science as culture, by analyzing its rhetoric, the primary means that people use to construct their social realities-their cultural environment, as it were. This analysis follows this path, considering scientific and public interest in astrobiology and SETI and focusing on scientific and official constructions of the two endeavors. This analysis will also consider whether and how scientific and public conceptions of astrobiology and SETI, which are related but at the same time separate endeavors, converge or diverge and whether and how these convergences or divergences affect the scientific authority, credibility, and legitimacy of these endeavors.

  17. Vanguard: A New Science Mission For Experimental Astrobiology

    NASA Astrophysics Data System (ADS)

    Ellery, A.; Wynn-Williams, D.; Edwards, H.; Dickensheets, D.; Welch, C.; Curley, A.

    As an alternative to technically and financially problemat ic sample return missions, a rover-mounted laser Raman spectrometer sensitive to biomolecules and their mineral substrata is a promising alternative in the search for evidence of former life on Mars. We presented a new remote in situ analysis package being designed for experimental astrobiology on terrestrial-type planetary surfaces. The science is based on the hypothesis that if life arose on Mars, the selective pressure of solar radiation would have led to the evolution of pigmented systems to harness the energy of sunlight and to protect cells from concurrent UV stress. Microbial communities would have therefore become stratified by the light gradient, and our remote system would penetrate the near-subsurface profile in a vertical transect of horizontal strata in ancient sediments (such as palaeolake beds). The system will include an extensive array of robotic support to translocate and deploy a Raman spectrometer detectors beneath the surface of Mars ­ it will comprise of a base station lander to support communications, a robotic micro-rover to permit well- separated triplicate profiles made by three ground-penetrating moles mounted in a vertical configuration. Each mole will deploy a tether carrying fibre optic cables coupling the Raman spectrometer onboard the rover and the side-scanning sensor head on the mole. The complete system has been named Vanguard, and it represents a close collaboration between a space robotics engineer (Ellery), an astrobiologist (Wynn-Williams), a molecular spectroscopist (Edwards), an opto-electronic technologist (Dickensheets), a spacecraft engineer (Welch) and a robotic vision specialist (Curley). The autonomy requirement for the Vanguard instrument requires that significant scientific competence is imparted to the instrument through an expert system to ensure that quick-look analysis is performed onboard in real-time as the mole penetrates beneath the surface.

    2003-12-01

    As teachers strive to improve the way science is taught in the classroom, many are turning to the interdisciplinary science of astrobiology as a way integrate inquiry effectively in the science classroom. However, it is generally recognized that teachers do not often have easy access to understandable and usable cutting-edge science to enrich their science lessons. Through the generous support of the NASA Astrobiology Institute (NAI), middle and high school teachers have the opportunity to learn current and provocative scientific results within the context of astrobiology as well as receive training in pedagogically sound methods of incorporating astrobiology appropriately in the classroom. In Astrobiology for Teachers, a 15-week on-line distance learning course co-sponsored by NAI, the National Science Teachers Association (NSTA) Professional Development Institute, National Teachers Enhancement Network (NTEN), Montana State University, and the Department of Astronomy at University of Arizona, teachers engage in a virtual classroom facilitated by an integrated teaching team of educators and scientists using a standards-based, inquiry curriculum. The collaborative nature of the course encourages, demonstrates, and enhances a professional exchange among scientists and educators which, in turn, fosters implementation of innovative science teaching in today's classroom.

  20. Thinking strategically about communications for the space sciences: the case of astrobiology

    NASA Astrophysics Data System (ADS)

    Billings, L.

    2007-12-01

    Ongoing concerns about public understanding of science and scientific literacy, coupled with the growing prominence of science in everyday life, demand that science experts know how to explain the work they do and the value it offers. Public funding of scientific research also argues for communications with the public about it. For research funded by NASA, a statutory requirement is in place to "provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." (1958 National Aeronautics and Space Act.) Public interest in space science is substantial, and advances in the field are rapid. Communicating about science is thus an especially important task for researchers working in the space sciences, as well as an obligation for those receiving public funding. This presentation will describe a communication strategy developed for NASA's Astrobiology Program, intended to aid communication among scientists within an expanding and broadly multidisciplinary field as well as communication about science with a range of external audiences. Conceived strategically, communication is an integral element of the overall work of a program or organization. Communication is conceived strategically in the Astrobiology Program. Astrobiology communication strategy offers a way of thinking about communication - an approach to communication, as it were - and provides guidance on methods, messages, tools, and audiences to be considered in implementation. It can help members of the astrobiology community to communicate about their work with experts - in their own fields and in others - and non-experts - employers, funders, policy makers, teachers, students, parents, citizens. It is designed to promote quality, consistency, and continuity in communication endeavors across the astrobiology program and to integrate these endeavors in program planning and activities. Implementation of a communication strategy for the Astrobiology

    One of the corner stones of the Research Platform on ExoLife, University of Vienna, Austria is public outreach and education with respect to astrobiology, exoplanets, and planetary sciences. Since 2009 several initiatives have been started by the Research Platform to concentrate the interest of students in and outside the University onto natural sciences. Astrobiology as a very interdisciplinary scientific discipline with questions like "Are we alone in the Universe?," "How unique is Earth as a planet?" or "How did life originate?" will fascinate youngsters and junior scientists (see [1]).

    INTRODUCTION This paper will report on and evaluate communication, education, and outreach initiatives conducted in conjunction with NASA Astrobiology Science and Technology for Exploring Planets (ASTEP) field campaigns, addressing the costs and benefits of linking students, teachers, and other interested citizens with researchers in the field. This paper will highlight success stories, lessons learned, and promising practices regarding educational programs in scientific research environments. The Astrobiology Program in the U.S. National Aeronautics and Space Administration's (NASA's) Science Mission Directorate studies the origin, evolution, distribution, and future of life in the universe. Public interest in astrobiology is great, and advances in the field are rapid. Hence, the Astrobiology Program supports the widest possible dissemination of timely and useful information about scientific discoveries, technology development, new knowledge, and greater understanding produced by its investigators, employing an approach described as strategic communication planning. That is, the Astrobiology Program aims to integrate communication, education, and outreach into all aspects of program planning and execution. The Program encourages all of its investigators to contribute to the ongoing endeavor of informing public audiences about Astrobiology. The ASTEP element of the Astrobiology Program sponsors terrestrial field campaigns to further scientific research and technology development relevant to future solar system exploration missions. ASTEP science investigations are designed to further biological research in terrestrial environments analogous to those found on other planets, past or present. ASTEP sponsors the development of technologies to enable remote searches for, and identification of, life in extreme environments. ASTEP supports systems-level field campaigns designed to demonstrate and validate the science and technology in extreme environments on Earth. This

    Abstract There is concern in many developed countries that school students are turning away from science. However, students may be choosing not to study science and dismissing the possibility of a scientific career because, in the junior secondary years, they gain a false view of science and the work of scientists. There is a disparity between science as it is portrayed at school and science as it is practiced. This paper describes a study to explore whether engaging in science through astrobiology outreach activities may improve students' understanding of the nature and processes of science, and how this may influence their interest in a career in science. The results suggest that the students attending these Mars research–related outreach activities are more interested in science than the average student but are lacking in understanding of aspects of the nature of science. A significant difference was detected between pre- and posttest understandings of some concepts of the nature of science. Key Words: Science education—School science—Creativity—Nature and processes of science—Attitudes—Astrobiology. Astrobiology 12, 1143–1153. PMID:23134090

    The question of the chemical origins of life is engraved in the European scientific patrimony as it can be traced back to the pioneer ideas of Charles Darwin, Louis Pasteur, and more recently to Alexander Oparin. During the last decades, the European community of origin of life scientists has organized seven out of the twelve International Conferences on the Origins of Life held since 1957. This community contributed also to enlarge the field of research to the study of life in extreme environments and to the search for extraterrestrial life, i.e. exobiology in its classical definition or astrobiology if one uses a more NASA-inspired terminology. The present paper aims to describe the European science background in exo/astrobiology as well as the project of a European Network of Exo/Astrobiology.

    Observations with radio telescopes address key problems in cosmology, astrobiology, heliophysics, and planetary science including the first light in the Universe (Cosmic Dawn), magnetic fields of extrasolar planets, particle acceleration mechanisms, and the lunar ionosphere. The Moon is a unique science platform because it allows access to radio frequencies that do not penetrate the Earth's ionosphere and because its far side is shielded from intense terrestrial emissions. The instrument packages and infrastructure needed for radio telescopes can be transported and deployed as part of Exploration activities, and the resulting science measurements may inform Exploration (e.g., measurements of lunar surface charging).

    With the budget process all but complete for next fiscal year, the National Science Foundation and the National Aeronautics and Space Administration observers were saying that science had not done that badly in Congress, for an election year. NSF got half the budget increase it requested, NASA two-thirds. The Space Station did well, at the expense of environmental and social programs, which are funded by Congress from the same pot of money as NASA and NSF.A House-Senate conference finished work on a $59 billion appropriations bill for the Department of Housing and Urban Development and independent agencies, including EPA, NASA, and NSF, in early August. The House and Senate then quickly passed the measure before their recess; the President is expected to sign it soon. Included in the Fiscal Year 1989 spending bill are $1,885 billion for NSF, a 9.8% increase over FY 1988, and $10.7 billion for NASA, 18.5% more than the year before.

    Astrobiology is defined in the 1996 NASA Strategic Plan as 'The study of the living universe.' At NASA's Ames Research Center, this endeavor encompasses the use of space to understand life's origin, evolution, and destiny in the universe. Life's origin refers to understanding the origin of life in the context of the origin and diversity of planetary systems. Life's evolution refers to understanding how living systems have adapted to Earth's changing environment, to the all-pervasive force of gravity, and how they may adapt to environments beyond Earth. Life's destiny refers to making long-term human presence in space a reality, and laying the foundation for understanding and managing changes in Earth's environment. The first Astrobiology Workshop brought together a diverse group of researchers to discuss the following general questions: Where and how are other habitable worlds formed? How does life originate? How have the Earth and its biosphere influenced each other over time? Can terrestrial life be sustained beyond our planet? How can we expand the human presence to Mars? The objectives of the Workshop included: discussing the scope of astrobiology, strengthening existing efforts for the study of life in the universe, identifying new cross-disciplinary programs with the greatest potential for scientific return, and suggesting steps needed to bring this program to reality. Ames has been assigned the lead role for astrobiology by NASA in recognition of its strong history of leadership in multidisciplinary research in the space, Earth, and life sciences and its pioneering work in studies of the living universe. This initial science workshop was established to lay the foundation for what is to become a national effort in astrobiology, with anticipated participation by the university community, other NASA centers, and other agencies. This workshop (the first meeting of its kind ever held) involved life, Earth, and space scientists in a truly interdisciplinary sharing

    2014-06-01

    The non-science major "Life in the Universe" class offers students many opportunities to explore topics such as whether or not to send manned missions to Mars, which jovian moon is a suitable candidate for harboring life, etc. Some of these topics are suited to being offered as projects. At Joliet Junior College, Joliet, IL, we offer this general education class every semester to around 40 students. We expect our students to complete three short essays in a semester, instead of doing one or two large projects. The essays enable students to be engaged more deeply with some aspects of the course than is usually possible in the classroom. Some of our essay topics are based on suggestions in the textbook, others have been developed by us. In this poster, we will report on the essay topics and the attitudes of our Fall 2013 and Spring 2014 students to such essays.

    AGU will present its inaugural Science Policy Conference, 30 April to 3 May 2012, at the Ronald Reagan Building and International Trade Center, located in downtown Washington, D. C. This conference will bring together leading scientists, policy makers, industry professionals, press, and other stakeholders to discuss natural hazards, natural resources, oceans, and Arctic science and the role these sciences play in serving communities. To bridge the science and policy fields, AGU plans to host this conference every 2 years and focus on the applications of Earth and space sciences to serve local and national communities. "Our nation faces a myriad of challenges such as the sustainability of our natural resources, current and future energy needs, and the ability to mitigate and adapt to natural and manmade hazards," said Michael McPhaden, president of AGU. "It is essential that policies to address these challenges be built on a solid foundation of credible scientific knowledge."

    One of the resources that evolved from the Bioastronomy 2007 meeting was an online interdisciplinary glossary of terms that might not be universally familiar to researchers in all sub-disciplines feeding into astrobiology. In order to facilitate comprehension of the presentations during the meeting, a database driven web tool for online glossary definitions was developed and participants were invited to contribute prior to the meeting. The glossary was downloaded and included in the conference registration materials for use at the meeting. The glossary web tool is has now been delivered to the NASA Astrobiology Institute so that it can continue to grow as an evolving resource for the astrobiology community.

    Tumbleweed is a wind-propelled long-range vehicle based on well-developed and tested technology, instrumented to perform surveys Mars analog environments for habitability and suitable for a variety of missions on Mars. Tumbleweeds are light-weight and relatively inexpensive, making it very attractive for multiple deployments or piggy-backing on a larger mission. Tumbleweeds with rigid structures are also being developed for similar applications. Modeling and testing have shown that a 6 meter diameter Tumbleweed is capable of climbing 25 hills, traveling over 1 meter diameter boulders, and ranging over a thousand kilometers. Tumbleweeds have a potential payload capability of about 10 kilograms with approximately 10-20 Watts of power. Stopping for science investigations can also be accomplished using partial deflation or other braking mechanisms. Surveys for Astrobiology and other applications of tumbleweeds are shown.

    2007-12-01

    A new era of planetary exploration - and the investigation of whether life exists or has existed beyond Earth - requires the development of biologically relevant instruments capable of extensive, autonomous operations on and below planetary surfaces. In collaboration with other agencies, NASA's Astrobiology Science and Technology for Exploring Planets (ASTEP) Program sponsors investigations focused on exploring the Earth's extreme environments through use of terrestrial field campaigns to develop a sound technical and scientific basis upon which to conduct a search for life or life-related molecules on other planets. The ASTEP Program is a science-driven exploration program exercising new science and operational/technological capabilities to enable this next generation of planetary exploration. One focus of ASTEP has been preparing for future missions to Europa, where the challenges of mass, power, volume are acute in accomplishing remote exploration, ice penetration, and following the lure of potential ocean-bottom features (~100km down!) such as hydrothermal venting. This poster will discuss the advantages of extreme-environment expeditions in preparing for the exploration of other worlds, and review current and future ASTEP-funded activities that contribute to Europa exploration. In addition, future mission concepts for Earth-based Europa exploration that might be proposed to a future ASTEP opportunity will be envisioned.

    Chemical composition affects virtually all aspects of astrobiology, from stellar astrophysics to molecular biology. We present a synopsis of the research results presented at the "Stellar Stoichiometry" Workshop Without Walls hosted at Arizona State University April 11-12, 2013, under the auspices of the NASA Astrobiology Institute. The results focus on the measurement of chemical abundances and the effects of composition on processes from stellar to planetary scales. Of particular interest were the scientific connections between processes in these normally disparate fields. Measuring the abundances of elements in stars and giant and terrestrial planets poses substantial difficulties in technique and interpretation. One of the motivations for this conference was the fact that determinations of the abundance of a given element in a single star by different groups can differ by more than their quoted errors. The problems affecting the reliability of abundance estimations and their inherent limitations are discussed. When these problems are taken into consideration, self-consistent surveys of stellar abundances show that there is still substantial variation (factors of ∼ 2) in the ratios of common elements (e.g., C, O, Na, Al, Mg, Si, Ca) important in rock-forming minerals, atmospheres, and biology. We consider how abundance variations arise through injection of supernova nucleosynthesis products into star-forming material and through photoevaporation of protoplanetary disks. The effects of composition on stellar evolution are substantial, and coupled with planetary atmosphere models can result in predicted habitable zone extents that vary by many tens of percent. Variations in the bulk composition of planets can affect rates of radiogenic heating and substantially change the mineralogy of planetary interiors, affecting properties such as convection and energy transport.

    A workshop was held (10/99) for high school students and teachers on astrobiology. NASA provided support through an IDEAS grant. Out of 63 qualified applicants, 29 were accepted: 22 students (11 minorities) and 7 teachers. The worship was held on 2 successive weekends. Activities included: culturing microbes from human skin, discussing 'what is life?', building and using a 2-inch refractive telescope and a van-Leeuwenhoek- type microscope (each participant built and kept them), listening to lectures by Dr. Richard Gelderman on detecting extra solar planets and by Dr. Richard Hoover on life in extreme environments. Other activities included: collecting samples and isolating micro-organisms from the lost river cave, studying microbial life from extreme environments in the laboratory, using the internet as a research tool and debating the logistics and feasibility of a lunar colony. Written evaluations of the workshop led to the following conclusions: 48% of the students considered a possible career in the biological and/or astrophysical sciences, and half of these stated they were spurred on by the workshop itself.

    The Georgia Tech Center for Ribosomal Origins and Evolution, a center funded by the NASA Astrobiology Institute, developed an educational program titled, "Life on the Edge: Astrobiology." The purpose of the program was to provide high school educators with the exposure, materials, and skills necessary to prepare our future workforce and to foster student interest in scientific discovery on Earth and throughout the universe. In an effort to promote and encourage entry into teaching careers, Georgia Tech paired teachers in the Georgia Intern-Fellowship for Teachers (GIFT) program with undergraduate students interested in becoming a teacher through the NSF Pre-Teaching REU program. The GIFT and Pre-Teaching fellows investigated extremophiles, which became the focus of a week-long, "Life on the Edge: Astrobiology " summer program developed by three high school educators, two undergraduate students and faculty in the Schools of Biology, and Chemistry and Biochemistry at Georgia Tech. Twenty high school students were introduced to hands-on activities, such as astrobiology inspired art and techniques such as genomic DNA purification, gel electrophoresis, and Polymerase Chain Reaction (PCR). The impact of the Astrobiology program on the GIFT researchers, Pre-Teaching REU students, high school students, and faculty are discussed.

    Online education is an emergent sector of formal education and Arizona State University (ASU) is a leader in offering online courses. One that garners very strong positive feedback on student surveys is Habitable Worlds, which is an interdisciplinary online science course offered every semester since Fall 2011. Primary goals of this course are to teach understanding of scientific reasoning and practices by using principles from trans-disciplinary research in astrobiology. To examine course outcomes we administered the Classroom Undergraduate Research Experience (CURE) survey, which has been previously developed to measure student experiences. Here we use the survey for the first time for an online course. The survey was taken before and after completing the course during the Fall 2014 and Spring 2015 semesters (N = 544). Here, we present students’ views of science represented by 22 questions on the survey. For the questions, students responded either "not applicable," "strongly disagree," "disagree," "neutral," "agree," or "strongly agree." In order to interpret the data, we divided the questions into three broader categories for analysis: students’ understanding of the scientific process, students’ scientific self-efficacy and students’ views on science teaching. We study how the sample of students changed their responses to each of the questions as a group by using a paired-samples sign test to gauge the statistical significance of the difference between pre and post responses. We further analyze how individual students changed their responses. For example, we designated a change from “strongly disagree” to “disagree” differently than a change from “agree” to “disagree” since the latter indicated a notable change in the student’s opinion. We found statistically significant changes on 12 of the 22 questions. These early results indicate that there are measurable changes on several identified course objectives. By measuring changes that

    2004-02-01

    The Euro3D RTN is an EU funded Research Training Network to foster the exploitation of 3D spectroscopy in Europe. 3D spectroscopy is a general term for spectroscopy of an area of the sky and derives its name from its two spatial + one spectral dimensions. There are an increasing number of instruments which use integral field devices to achieve spectroscopy of an area of the sky, either using lens arrays, optical fibres or image slicers, to pack spectra of multiple pixels on the sky (``spaxels'') onto a 2D detector. On account of the large volume of data and the special methods required to reduce and analyse 3D data, there are only a few centres of expertise and these are mostly involved with instrument developments. There is a perceived lack of expertise in 3D spectroscopy spread though the astronomical community and its use in the armoury of the observational astronomer is viewed as being highly specialised. For precisely this reason the Euro3D RTN was proposed to train young researchers in this area and develop user tools to widen the experience with this particular type of data in Europe. The Euro3D RTN is coordinated by Martin M. Roth (Astrophysikalisches Institut Potsdam) and has been running since July 2002. The first Euro3D science conference was held in Cambridge, UK from 22 to 23 May 2003. The main emphasis of the conference was, in keeping with the RTN, to expose the work of the young post-docs who are funded by the RTN. In addition the team members from the eleven European institutes involved in Euro3D also presented instrumental and observational developments. The conference was organized by Andy Bunker and held at the Institute of Astronomy. There were over thirty participants and 26 talks covered the whole range of application of 3D techniques. The science ranged from Galactic planetary nebulae and globular clusters to kinematics of nearby galaxies out to objects at high redshift. Several talks were devoted to reporting recent observations with newly

    We teach an astrobiology general education course each semester at Joliet Junior College, IL. Over 40 students enroll in the course each semester at this community college. Due to the interdisciplinary nature of astrobiology and to enable students to explore the course material more deeply, we offer two group projects each semester. One project is related to Mars, while the other deals with extrasolar planets. Students make poster projects which are displayed in the college for all to enjoy. In Fall 09, students were asked for their feedback on these projects. Based on their responses, in Spring 10, small changes were made to the assignments. Spring 10 students will be surveyed to find out how they feel about such projects. We will provide details of the projects and the results of both Fall 09 and Spring 10 surveys. We will attempt to gauge the effect that the minor alterations had on these assignments.

    In the opening weeks of 1998 a news article in the British journal Nature reported that NASA was about to enter biology in a big way. A "virtual" Astrobiology Institute was gearing up for business, and NASA administrator Dan Goldin told his external advisory council that he would like to see spending on the new institute eventually reach $100 million per year. "You just wait for the screaming from the physical scientists (when that happens)," Goldin was quoted as saying. Nevertheless, by the time of the second Astrobiology Science Conference in 2002, attended by seven hundred scientists from many disciplines, NASA spending on astrobiology had reached nearly half that amount and was growing at a steady pace. Under NASA leadership numerous institutions around the world applied the latest scientific techniques in the service of astrobiology's ambitious goal: the study of what NASA's 1996 Strategic Plan termed the "living universe." This goal embraced nothing less than an understanding of the origin, history, and distribution of life in the universe, including Earth. Astrobiology, conceived as a broad interdisciplinary research program, held the prospect of being the science for the twenty-first century which would unlock the secrets to some of the great questions of humanity. It is no surprise that these age-old questions should continue into the twenty-first century. But that the effort should be spearheaded by NASA was not at all obvious to those - inside and outside the agency - who thought NASA's mission was human spaceflight, rather than science, especially biological science. NASA had, in fact, been involved for four decades in "exobiology," a field that embraced many of the same questions but which had stagnated after the 1976 Viking missions to Mars. In this volume we tell the colorful story of the rise of the discipline of exobiology, how and why it morphed into astrobiology at the end of the twentieth century, and why NASA was the engine for both the

    Abstract Future astrobiological missions to Mars are likely to emphasize the use of rovers with in situ petrologic capabilities for selecting the best samples at a site for in situ analysis with onboard lab instruments or for caching for potential return to Earth. Such observations are central to an understanding of the potential for past habitable conditions at a site and for identifying samples most likely to harbor fossil biosignatures. The Multispectral Microscopic Imager (MMI) provides multispectral reflectance images of geological samples at the microscale, where each image pixel is composed of a visible/shortwave infrared spectrum ranging from 0.46 to 1.73 μm. This spectral range enables the discrimination of a wide variety of rock-forming minerals, especially Fe-bearing phases, and the detection of hydrated minerals. The MMI advances beyond the capabilities of current microimagers on Mars by extending the spectral range into the infrared and increasing the number of spectral bands. The design employs multispectral light-emitting diodes and an uncooled indium gallium arsenide focal plane array to achieve a very low mass and high reliability. To better understand and demonstrate the capabilities of the MMI for future surface missions to Mars, we analyzed samples from Mars-relevant analog environments with the MMI. Results indicate that the MMI images faithfully resolve the fine-scale microtextural features of samples and provide important information to help constrain mineral composition. The use of spectral endmember mapping reveals the distribution of Fe-bearing minerals (including silicates and oxides) with high fidelity, along with the presence of hydrated minerals. MMI-based petrogenetic interpretations compare favorably with laboratory-based analyses, revealing the value of the MMI for future in situ rover-mediated astrobiological exploration of Mars.

    This is Volume 1 of 3 of the 2000 Microgravity Material Science Conference that was held June 6-8 at the Von Braun Center, Huntsville, Alabama. It was organized by the Microgravity Materials Science Discipline Working Group, sponsored by the Microgravity Research Division (MRD) at NASA Headquarters, and hosted by NASA Marshall Space Flight Center and the Alliance for Microgravity Materials Science and Applications (AMMSA). It was the fourth NASA conference of this type in the microgravity materials science discipline. The microgravity science program sponsored approx. 200 investigators, all of whom made oral or poster presentations at this conference. In addition, posters and exhibits covering NASA microgravity facilities, advanced technology development projects sponsored by the NASA Microgravity Research Division at NASA Headquarters, and commercial interests were exhibited. The purpose of the conference was to inform the materials science community of research opportunities in reduced gravity and to highlight the Spring 2001 release of the NASA Research Announcement (NRA) to solicit proposals for future investigations.

    There are many advocates for the human exploration of Mars who wax poetical when discussing how good it is going to be, but there are only a few who may be willing to write requirements for how much direct human surface exploration on Mars needs to be possible before attempting it is worth the investment, or to compare modes of human exploration to see which one is most cost-efficient for the initial human missions to Mars (assuming that humans working in near-Mars space is a goal in and of itself. For example, the recent MEPAG Scientific Objectives for the Human Exploration of Mars Science Analysis Group (MEPAG HSO-SAG) [1] stated that "A defensible evaluation of surface science operations options and candidate scenarios cannot be done at this time - we recommend deferring this to a future team." Alternatively [e.g., 2], there are considerations of the science that can be done from the martian moon Phobos that do not require surface operations on Mars at all, except by robots controlled through low-latency telepresence. The promise of how to deliver better Mars science for the money (and risk) will be discussed in this paper, and some estimates made on how often a human has to step outside on Mars (and step back in) to accomplish more science than a telepresent rover. We will also look at what the estimates of contamination from on-site human explorers can mean to the search for possible indigenous life on Mars. Some [3] say that Mars is already "contaminated" by Earth organisms brought to Mars from Earth through impact-generated bolide exchanges, but (as noted in [4]) that statement suggests that they do not really hold a solid concept of what contamination is, and what it may mean to both our understanding of the pre-human past on Mars, as well as to the preservation of Mars resources for future human inhabitants.

    Future astrobiological missions to Mars are likely to emphasize the use of rovers with in situ petrologic capabilities for selecting the best samples at a site for in situ analysis with onboard lab instruments or for caching for potential return to Earth. Such observations are central to an understanding of the potential for past habitable conditions at a site and for identifying samples most likely to harbor fossil biosignatures. The Multispectral Microscopic Imager (MMI) provides multispectral reflectance images of geological samples at the microscale, where each image pixel is composed of a visible/shortwave infrared spectrum ranging from 0.46 to 1.73 μm. This spectral range enables the discrimination of a wide variety of rock-forming minerals, especially Fe-bearing phases, and the detection of hydrated minerals. The MMI advances beyond the capabilities of current microimagers on Mars by extending the spectral range into the infrared and increasing the number of spectral bands. The design employs multispectral light-emitting diodes and an uncooled indium gallium arsenide focal plane array to achieve a very low mass and high reliability. To better understand and demonstrate the capabilities of the MMI for future surface missions to Mars, we analyzed samples from Mars-relevant analog environments with the MMI. Results indicate that the MMI images faithfully resolve the fine-scale microtextural features of samples and provide important information to help constrain mineral composition. The use of spectral endmember mapping reveals the distribution of Fe-bearing minerals (including silicates and oxides) with high fidelity, along with the presence of hydrated minerals. MMI-based petrogenetic interpretations compare favorably with laboratory-based analyses, revealing the value of the MMI for future in situ rover-mediated astrobiological exploration of Mars.

    In recent years, science has become inextricably linked to the political process. As such, it is more important now than ever for science to forge a better relationship with politics, for the health of both science and society. To help meet this need, the American Geophysical Union (AGU) strives to engage its members, shape policy, and inform society about the excitement of Earth and space science and its role in developing solutions for the sustainability of the planet. In June 2013, AGU held its second annual Science Policy Conference in Washington, D.C. The goal of the conference is to provide a new forum for diverse discussions and viewpoints on the challenges and opportunities of science policy, with a focus on applications of Earth and space science that serve local, national, and international communities. The meeting brought together more than 300 scientists, policy makers, industry professionals, members of the press, and other stakeholders to discuss the topics concerning the Arctic, climate change, oceans, energy, technology and infrastructure, and natural hazards science as they relate to challenges impacting society. Sessions such as 'The Water-Energy Nexus,' 'Potential for Megadisasters,' 'The Changing Ocean and Impacts on Human Health,' and 'Drowning and Drought: Agricultural Impacts of Climate Change' are examples of some of the intriguing and timely science policy issues addressed at the conference. The findings from the conference were used to develop a summary report. The report highlights key facts and figures to be used as a resource in discussions with policy makers and other stakeholders regarding the conference topics. This presentation will discuss the goals and outcomes of the conference and how the event represents one of the many ways AGU is approaching its 'Science and Society' priority objective as part of the Union's strategic plan; namely by increasing the effectiveness and recognition of AGU among policy makers as an authoritative

    We organized astrobiology lectures in the Eotvos Lorand University of Sciences and the Polaris Observatory in 2002. We present here the "Drake matrix" for the comparison of the astrobiological potential of different bodies [1], and astrobiology matrix for the visualization of the interdisciplinary connections between different fields of astrobiology. Conclusion: In Hungary it is difficult to integrate astrobiology in the education system but the great advantage is that it can connect different scientific fields and improve the view of students. We would like to get in contact with persons and organizations who already have experience in the education of astrobiology.

    Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and planetary science and considers its potential relevance to the origins of life on Earth and elsewhere. Guided by the review papers in this book, the concluding chapter aims to identify key questions to motivate future research and stimulate astrobiological applications of current and future research facilities and space missions. Today’s rich array of new spacecraft, telescopes and dedicated scientists promises a steady flow of discoveries and insights that will ultimately lead us to the answers we seek.

    Astrobiology, the search for life in the universe, has fascinating research areas that can excite students and teachers about science. Its integrative nature, relating to astronomy, geology, oceanography, physics, and chemistry, can be used to encourage students to pursue physical sciences careers. Since 2004, the University of Hawaii NASA Astrobiology Institute (NAI) team scientists have shared their research with secondary teachers at our ALI’I national teacher program to promote the inclusion of astrobiology topics into science courses. Since 2007, our NAI team has co-sponsored the HI STAR program for Hawaii’s middle and high school students to work on authentic astronomy research projects and to be mentored by astronomers. The students get images of asteroids, comets, stars, and extrasolar planets from the Faulkes Telescope North located at Haleakala Observatories on the island of Maui and owned by Las Cumbres Observatory Global Telescope network. They also do real time observing with DeKalb Observatory telescope personally owned by Donn Starkey who willing allows any student access to his telescope. Student project results include awards at the Hawaii State Science Fair and the Intel International Science and Engineering Fair. We believe that research experience stimulates these students to select STEM (science, technology, engineering and mathematics) majors upon entering college so a longitudinal study is being done. Plans are underway with California and Hawaii ALI’I teachers cooperating on a joint astronomy classroom project. International collaborations with Brazil, Portugal, and Italy astronomers have begun. We envision joint project between hemispheres and crossing time zones. The establishment of networking teachers, astronomers, students and educator liaisons will be discussed.

    Billings, Linda

    The narrative power of astrobiology: Telling the story of the quest to understand life's origins and the search for evidence of extraterrestrial life INTRODUCTION The story of the origins and evolution of life is a narrative with nearuniversal appeal. The story of life on Earth is meaningful to all people, and the search for life elsewhere is appealing across cultural boundaries. The U.S. National Aeronautics and Space Administration (NASA) funds an Astrobiology Program in NASA's Science Mission Directorate that is dedicated to the study of the origin, evolution, distribution, and future of life in the universe. Because public interest in astrobiology is great and advances in the field are rapid, the NASA Astrobiology Program aims to integrate communication, education, and outreach into all aspects of program planning and execution. This strategic approach to communication is intended to promote the widest possible dissemination of timely and useful information about scientific discoveries, technology development, new knowledge, and greater understanding produced by the Astrobiology Program. This paper will address how scientists in the field of astrobiology can participate in the telling of an ongoing story of interest to multicultural audiences and why it is important to tell this story. SUMMARY Astrobiology research addresses three fundamental questions: How does life begin and evolve? Is there life beyond Earth and how can we detect it? What is the future of life on Earth and in the universe? The field of astrobiology is an endeavor that brings together researchers in a broad range of disciplines including Earth and planetary science, astrophysics, heliophysics, microbiology and evolutionary biology, and cosmochemistry. Goals of the NASA Astrobiology Program range from determining the nature and distribution of habitable environments in the Solar System and beyond to understanding the emergence of life from cosmic and planetary precursors, the interaction of

    Synthetic biology - the design and construction of new biological parts and systems and the redesign of existing ones for useful purposes - has the potential to transform fields from pharmaceuticals to fuels. Our lab has focused on the potential of synthetic biology to revolutionize all three major parts of astrobiology: Where do we come from? Where are we going? and Are we alone? For the first and third, synthetic biology is allowing us to answer whether the evolutionary narrative that has played out on planet earth is likely to have been unique or universal. For example, in our lab we are re-evolving the biosynthetic pathways of amino acids in order to understand potential capabilities of an early organism with a limited repertoire of amino acids and developing techniques for the recovery of metals from spent electronics on other planetary bodies. And what about the limits for life? Can we create organisms that expand the envelope for life? In the future synthetic biology will play an increasing role in human activities both on earth, in fields as diverse as human health and the industrial production of novel bio-composites. Beyond earth, we will rely increasingly on biologically-provided life support, as we have throughout our evolutionary history. In order to do this, the field will build on two of the great contributions of astrobiology: studies of the origin of life and life in extreme environments.

    2003-01-01

    The Second SIAM Conference on Computational Science and Engineering was held in San Diego from February 10-12, 2003. Total conference attendance was 553. This is a 23% increase in attendance over the first conference. The focus of this conference was to draw attention to the tremendous range of major computational efforts on large problems in science and engineering, to promote the interdisciplinary culture required to meet these large-scale challenges, and to encourage the training of the next generation of computational scientists. Computational Science & Engineering (CS&E) is now widely accepted, along with theory and experiment, as a crucial third mode of scientific investigation and engineering design. Aerospace, automotive, biological, chemical, semiconductor, and other industrial sectors now rely on simulation for technical decision support. For federal agencies also, CS&E has become an essential support for decisions on resources, transportation, and defense. CS&E is, by nature, interdisciplinary. It grows out of physical applications and it depends on computer architecture, but at its heart are powerful numerical algorithms and sophisticated computer science techniques. From an applied mathematics perspective, much of CS&E has involved analysis, but the future surely includes optimization and design, especially in the presence of uncertainty. Another mathematical frontier is the assimilation of very large data sets through such techniques as adaptive multi-resolution, automated feature search, and low-dimensional parameterization. The themes of the 2003 conference included, but were not limited to: Advanced Discretization Methods; Computational Biology and Bioinformatics; Computational Chemistry and Chemical Engineering; Computational Earth and Atmospheric Sciences; Computational Electromagnetics; Computational Fluid Dynamics; Computational Medicine and Bioengineering; Computational Physics and Astrophysics; Computational Solid Mechanics and Materials; CS

    The NASA Astrobiology Roadmap provides guidance for research and technology development across the NASA enterprises that encompass the space, Earth, and biological sciences. The ongoing development of astrobiology roadmaps embodies the contributions of diverse scientists and technologists from government, universities, and private institutions. The Roadmap addresses three basic questions: How does life begin and evolve, does life exist elsewhere in the universe, and what is the future of life on Earth and beyond? Seven Science Goals outline the following key domains of investigation: understanding the nature and distribution of habitable environments in the universe, exploring for habitable environments and life in our own solar system, understanding the emergence of life, determining how early life on Earth interacted and evolved with its changing environment, understanding the evolutionary mechanisms and environmental limits of life, determining the principles that will shape life in the future, and recognizing signatures of life on other worlds and on early Earth. For each of these goals, Science Objectives outline more specific high-priority efforts for the next 3-5 years. These 18 objectives are being integrated with NASA strategic planning.

The Roadmap addresses three basic questions: how does life begin and evolve, does life exist elsewhere in the universe, and what is the future of life on Earth and beyond? Seven Science Goals outline the following key domains of investigation: understanding the nature and distribution of habitable environments in the universe, exploring for habitable environments and life in our own Solar System, understanding the emergence of life, determining how early life on Earth interacted and evolved with its changing environment, understanding the evolutionary mechanisms and environmental limits of life, determining the principles that will shape life in the future, and recognizing signatures of life on other worlds and on early Earth. For each of these goals, Science Objectives outline more specific high priority efforts for the next three to five years. These eighteen objectives are being integrated with NASA strategic planning.

    Committee On The Review Of The Nasa Astrobiology Institute, National Research Council

    Astrobiology is a scientific discipline devoted to the study of life in the universe - its origin, evolution, distribution, and future. In 1997, NASA established an Astrobiology program (the NASA Astrobiology Institute - NAI) as a result of a series of new results from solar system exploration and astronomical research in the mid-1990s together with advances in the biological sciences. To help evaluate the NAI, NASA asked the NRC to review progress made by the Institute in developing the field of astrobiology. This book presents an evaluation of NAI's success in meeting its goals for fostering interdisciplinary research, training future astrobiology researchers, providing scientific and technical leadership, exploring new research approaches with information technology, and supporting outreach to K-12 education programs.

    Chirality is an excellent indicator of life, but naturally occurring terrestrial and extra-terrestrial samples nearly always exhibit massive depolarizing light scattering (DLS). This problem bears a striking resemblance to that of developing a chirality-based non-invasive glucose monitor for diabetics. Both applications require a lightweight, compact, efficient, and robust polarimeter that can operate despite significant DLS. So for astrobiological applications, we developed a polarimeter that was inspired from a polarimetry technique previously investigated for non-invasive in-vivo glucose-sensing. Our polarimeter involves continuously rotating the plane of linear polarization of a laser beam to probe a sample with DLS, and analyzing its transmission with a fixed analyzer to obtain a sinusoidal voltage signal. We lock-in detect this signal using a reference signal from an analogous set up without any sample. With milk as a scatterer, we find that this polarimeter detects chirality in the presence of three orders of magnitude more DLS than conventional polarimeters. It can accurately measure 0.1° of polarization rotation in the presence of 15% milk.

  19. Astrobiology and the Biological Universe

    NASA Astrophysics Data System (ADS)

    Dick, S. J.

    2002-12-01

    Four hundred years ago two astronomical world views hung in the balance: the geocentric and the heliocentric. Today astronomy faces a similar choice between two grand world views: a purely physical universe, in which cosmic evolution commonly ends in planets, stars and galaxies, and a biological universe, in which cosmic evolution routinely results in life, mind and intelligence. Astrobiology is the science providing the data to make this critical choice. This 20th century overview shows how we have arrived at the view that cosmic evolution may have resulted in life and intelligence in the universe. It examines how our astronomical world view has changed over the last century, recalls the opinions of astronomical pioneers like Russell, Shapley, and Struve on life in the universe, and shows how planetary science, planetary systems science, origins of life studies and SETI have combined to form a new discipline. Astrobiology now commands \\$50 million in direct funding from NASA, funds 15 Astrobiology Institute members around the country and four affiliates around the world, and seeks to answer one of astronomy's oldest questions. Whether we live in a mostly physical universe, as exemplified in Isaac Asimov's Foundation series, or in a biological universe, as portrayed in Arthur C. Clarke's works, this reality will have profound consequences, no less than the Copernican theory. Astrobiology also looks to the future of life; taking a long-term ``Stapledonian" view, it is possible we may live in a postbiological universe.

  20. The narrative power of astrobiology

    Billings, Linda

    The narrative power of astrobiology: Telling the story of the quest to understand life's origins and the search for evidence of extraterrestrial life INTRODUCTION The story of the origins and evolution of life is a narrative with nearuniversal appeal. The story of life on Earth is meaningful to all people, and the search for life elsewhere is appealing across cultural boundaries. The U.S. National Aeronautics and Space Administration (NASA) funds an Astrobiology Program in NASA's Science Mission Directorate that is dedicated to the study of the origin, evolution, distribution, and future of life in the universe. Because public interest in astrobiology is great and advances in the field are rapid, the NASA Astrobiology Program aims to integrate communication, education, and outreach into all aspects of program planning and execution. This strategic approach to communication is intended to promote the widest possible dissemination of timely and useful information about scientific discoveries, technology development, new knowledge, and greater understanding produced by the Astrobiology Program. This paper will address how scientists in the field of astrobiology can participate in the telling of an ongoing story of interest to multicultural audiences and why it is important to tell this story. SUMMARY Astrobiology research addresses three fundamental questions: How does life begin and evolve? Is there life beyond Earth and how can we detect it? What is the future of life on Earth and in the universe? The field of astrobiology is an endeavor that brings together researchers in a broad range of disciplines including Earth and planetary science, astrophysics, heliophysics, microbiology and evolutionary biology, and cosmochemistry. Goals of the NASA Astrobiology Program range from determining the nature and distribution of habitable environments in the Solar System and beyond to understanding the emergence of life from cosmic and planetary precursors, the interaction of

  3. Lower Secondary Students' Views in Astrobiology

    2013-01-01

    Astrobiology is, on a profound level, about whether life exists outside of the planet Earth. The question of existence of life elsewhere in the universe has been of interest to many societies throughout history. Recently, the research area of astrobiology has grown at a fast rate, mainly due to the development of observational methods, and the media is frequently reporting on new research findings. International surveys show that astrobiology questions are among those that interest young people the most. The popularity of astrobiology and the way it captures much science content makes it an interesting area for science teaching. However, there is very little research directly focused upon students' views in astrobiology. The study reported in this paper draws from the answers of 186 Swedish lower secondary students (16 years old) to a questionnaire, with closed and open-ended questions regarding their views of issues in astrobiology. The study was guided by the worldview theory (Cobern 1991; Cobern, Science Education 80(5):579-610, 1996; Cobern, Science and Education 9:219-246, 2000). The results show that even though basic reasoning in astrobiology is known by a majority of the students, there is a considerable number of students, for whom this is not the case. Furthermore, it was found that for all questions, there are students answering in different ways when asked to describe their own view and the view they associate with science researchers. The implications of the study for further research and for the teaching of astrobiology in science class are discussed.

    New technologies, such as the emerging field of geoneutrino research, and new data sets from the Cassini and Voyager spacecrafts have captured the attention of scientists, prompting them to freshly explore the furthest reaches of their fields, from the Earth's deep interior to the outer solar system and beyond. Several sessions at the 23-26 May 2006 AGU Joint Assembly in Baltimore, Md., will offer a glimpse into these new investigations, while others are devoted to discussing plans for coordinated research efforts during upcoming international science years. One session on ``Geoneutrinos: A New Tool for the Study of the Solid Earth'' (U41F) will take place on Wednesday, 25 May at 8:30 A.M. Geoneutrinos, which are anti-neutrinos produced by the radioactive decay of uranium, thorium, and potassium housed within the Earth, have been detected by Japan's Kamioka Liquid-Scintillator Anti-Neutrino Detector (KamLAND) apparatus. With such information, scientists for the first time can directly estimate the amount of radioactive elements present in different regions of the Earth.

  5. Astrosociological Implications of Astrobiology (Revisited)

    NASA Astrophysics Data System (ADS)

    Pass, Jim

    2010-01-01

    Supporters of astrobiology continue to organize the field around formalized associations and organizations under the guise of the so-called ``hard'' sciences (e.g., biology and the related physical/natural sciences). The so-called ``soft'' sciences-including sociology and the other social sciences, the behavioral sciences, and the humanities-remain largely separated from this dynamically growing field. However, as argued in this paper, space exploration involving the search for extraterrestrial life should be viewed as consisting of two interrelated parts (i.e., two sides of the same coin): astrobiology and astrosociology. Together, these two fields broadly combine the two major branches of science as they relate to the relationship between human life and alien life, as appropriate. Moreover, with a formalized system of collaboration, these two complimentary fields would also focus on the implications of their research to human beings as well as their cultures and social structures. By placing the astrosociological implications of astrobiology at a high enough priority, scientists interested in the search for alien life can augment their focus to include the social, cultural, and behavioral implications that were always associated with their work (yet previously overlooked or understated, and too often misunderstood). Recognition of the astrosociological implications expands our perception about alien life by creating a new emphasis on their ramifications to human life on Earth.

  6. Assessment of the NASA Astrobiology Institute

    2008-01-01

    Astrobiology is a scientific discipline devoted to the study of life in the universe--its origins, evolution, distribution, and future. It brings together the physical and biological sciences to address some of the most fundamental questions of the natural world: How do living systems emerge? How do habitable worlds form and how do they evolve? Does life exist on worlds other than Earth? As an endeavor of tremendous breadth and depth, astrobiology requires interdisciplinary investigation in order to be fully appreciated and examined. As part of a concerted effort to undertake such a challenge, the NASA Astrobiology Institute (NAI) was established in 1998 as an innovative way to develop the field of astrobiology and provide a scientific framework for flight missions. Now that the NAI has been in existence for almost a decade, the time is ripe to assess its achievements. At the request of NASA's Associate Administrator for the Science Mission Directorate (SMD), the Committee on the Review of the NASA Astrobiology Institute undertook the assignment to determine the progress made by the NAI in developing the field of astrobiology. It must be emphasized that the purpose of this study was not to undertake a review of the scientific accomplishments of NASA's Astrobiology program, in general, or of the NAI, in particular. Rather, the objective of the study is to evaluate the success of the NAI in achieving its stated goals of: 1. Conducting, supporting, and catalyzing collaborative interdisciplinary research; 2. Training the next generation of astrobiology researchers; 3. Providing scientific and technical leadership on astrobiology investigations for current and future space missions; 4. Exploring new approaches, using modern information technology, to conduct interdisciplinary and collaborative research among widely distributed investigators; and 5. Supporting outreach by providing scientific content for use in K-12 education programs, teaching undergraduate classes, and

    This review reports the Brazilian history in astrobiology, as well as the first delineation of a vision of the future development of the field in the country, exploring its abundant biodiversity, highly capable human resources and state-of-the-art facilities, reflecting the last few years of stable governmental investments in science, technology and education, all conditions providing good perspectives on continued and steadily growing funding for astrobiology-related research. Brazil is growing steadily and fast in terms of its worldwide economic power, an effect being reflected in different areas of the Brazilian society, including industry, technology, education, social care and scientific production. In the field of astrobiology, the country has had some important landmarks, more intensely after the First Brazilian Workshop on Astrobiology in 2006. The history of astrobiology in Brazil, however, is not so recent and had its first occurrence in 1958. Since then, researchers carried out many individual initiatives across the country in astrobiology-related fields, resulting in an ever growing and expressive scientific production. The number of publications, including articles and theses, has particularly increased in the last decade, but still counting with the effort of researchers working individually. That scenario started to change in 2009, when a formal group of Brazilian researchers working with astrobiology was organized, aiming at congregating the scientific community interested in the subject and to promote the necessary interactions to achieve a multidisciplinary work, receiving facilities and funding from the University de Sao Paulo and other funding agencies.

    Abstract This paper reports recent efforts to gather experts from the humanities and social sciences along with astrobiologists to consider the cultural, societal, and psychological implications of astrobiology research and exploration. We began by convening a workshop to draft a research roadmap on astrobiology's societal implications and later formed a Focus Group on Astrobiology and Society under the auspices of the NASA Astrobiology Institute (NAI). Just as the Astrobiology Science Roadmap and various astrobiology science focus groups have helped researchers orient and understand their work across disciplinary contexts, our intent was to apply the same approach to examine areas beyond the physical and life sciences and expand interdisciplinary interaction and scholarly understanding. These efforts continue as an experiment in progress, with an open invitation to interested researchers—astrobiologists as well as scholars in the humanities and social sciences—to become involved in research, analysis, and proactive discussions concerning the potential impacts of astrobiology on society as well as the possible impacts of society on progress in astrobiology.

    Sik, A.; Simon, T.

    Background In connection with the complex planetology-education in Hungary [1] we have compiled an Astrobiology coursebook - as a base of its teaching in universities and perhaps in secondary schools as well. We tried to collect and assemble in a logical and thematical order the scientific breakthroughs of the last years, that made possible the fast improvement of astrobiology. The followings are a kind of summary of these. Introduction - The ultimate science Astrobiology is a young science, that search for the possibility, forms and places of extraterrestrial life. But it is not SETI, because do not search for intelligent life, just for living organisms, so SETI is a part of astrobiology. and an extremely important statement: we can search for life-forms that similar to terrestrial life in physiology so we can recognize it as life. Astrobiology is one of the most dynamical-developing sciences of the 21st century. To determine its boundaries is difficult because the complex nature of it: astrobiology melt into itself lot of other sciences, like a kind of ultimate science. The fundamental questions are very simple [2]: When, where and how converted the organic matter into life?; How does life evolve in the Universe?; Has it appeared on other planets?; How does it spread in time and space?; and What is the future of terrestrial life? However, trying to find the answers is quite difficult. So an astrobiologist has to be aware of the basics of astronomy, space research, earth and planetary sciences, and life sciences (mainly ecology, genetics, molecular and evolution biology). But it is not enough - the newest results of these at least as important as the basic knowledge. Part I. - Astro 1. Exoplanets 1995 was a particular year in astronomy: we have found the first planet out of the Solar System. Since that time the discovery of exoplanets progress fast: nowdays more than 80 examples are known and just 6 years passed [3]. The detailed analysis of these distant objects

    The new discipline of astrobiology addresses fundamental questions about life in the universe: "Where did we come from?" "Are we alone in the universe?" "What is our future beyond the Earth?" Developing capabilities in biotechnology, informatics, and space exploration provide new tools to address these old questions. The U.S. National Aeronautics and Space Administration (NASA) has encouraged this new discipline by organizing workshops and technical meetings, establishing a NASA Astrobiology Institute, providing research funds to individual investigators, ensuring that astrobiology goals are incorporated in NASA flight missions, and initiating a program of public outreach and education. Much of the initial effort by NASA and the research community was focused on determining the technical content of astrobiology. This paper discusses the initial answer to the question "What is astrobiology?" as described in the NASA Astrobiology Roadmap.

    In the context of science education globalization, the International Conference on Science Education was held in Nanjing, China, in October 2012. The purpose of this conference was to provide a forum for science education researchers from China and from the rest of the world to exchange research ideas and best practices in science education. A call for papers for a special issue of the Journal of Science Education and Technology was made to all conference participants, and a set of six articles was resulted from a standard peer review process. This set of six articles provides a snapshot of research in China and in some other countries, and represents a dialogue between Chinese science education researchers and science education researchers from other countries. We call for more exchange and collaboration in science education between China and the rest of the world.

    2004-12-01

    In collaboration with the Australian Centre for Astrobiology (ACA), and NASA Learning Technologies (NLT), and utilizing the powerful visualization capabilities of their "World Wind" software, the NASA Astrobiology Institute (NAI) is crafting a prototype "Astrobiology Field Guide" to bring the field experiences and stories of astrobiology science to the public and classrooms around the world. The prototype focuses on one region in particular - The Pilbara in Western Australia. This first Field Guide "hotspot" is an internationally recognized area hosting the best known example of the earliest evidence of life on Earth - a stromatolitic chert precipitation in the 3.45 Ga Warrawoona Group. The goal of the Astrobiology Field Guide is to engage students of all ages with the ongoing field expeditions of today's astrobiologists as they explore the ends of the Earth searching for clues to life's origin, evolution, and distribution in the Universe. The NAI hopes to expand this Field Guide to include many more astrobiologically relevant areas across the globe such as Cuatro Cienegas in Mexico, the Rio Tinto in Spain, Yellowstone National Park in the US, and the Lost City hydrothermal vent field on the mid-Atlantic ridge - and possibly sites on Mars. To that end, we will be conducting feasibility studies and evaluations with informal and formal education contacts. The Astrobiology Field Guide is also serving as a cornerstone to educational materials being developed focused on the Pilbara region for use in classrooms in Australia, the UK, and potentially the US. These materials are being developed by the Australian Centre for Astrobiology, and the ICT Innovations Centre at Macquarie University in Sydney, in collaboration with the NAI and the Centre for Astronomy and Science Education at the University of Glamorgan in the UK.

  16. Astrobiology Undergraduate Education: Students' Knowledge and Perceptions of the Field

    2009-04-01

    With the field of astrobiology continually evolving, it has become increasingly important to develop and maintain an educational infrastructure for the next generation of astrobiologists. In addition to developing more courses and programs for students, it is essential to monitor the learning experiences and progress of students taking these astrobiology courses. At the University of Florida, a new pilot course in astrobiology was developed that targeted undergraduate students with a wide range of scientific backgrounds. Pre- and post-course surveys along with knowledge assessments were used to evaluate the students' perceived and actual learning experiences. The class incorporated a hybrid teaching platform that included traditional in-person and distance learning technologies. Results indicate that undergraduate students have little prior knowledge of key astrobiology concepts; however, post-course testing demonstrated significant improvements in the students' comprehension of astrobiology. Improvements were not limited to astrobiology knowledge. Assessments revealed that students developed confidence in science writing as well as reading and understanding astrobiology primary literature. Overall, student knowledge of and attitudes toward astrobiological research dramatically increased during this course, which demonstrates the ongoing need for additional astrobiology education programs as well as periodic evaluations of those programs currently underway. Together, these approaches serve to improve the overall learning experiences and perceptions of future astrobiology researchers.

    be a prime astrobiologically oriented target for future exploration of Saturn's largest satellite. Cassini-Huygens has shown that the chemical composition of Titan's aerosols is similar to that of laboratory Titan's tholins. The behavior of those tholins when sub-mitted to high solar UV radiation has recently been studied in Earth orbit. The results show a slight but complex photodegradation in some cases. Moreover, recent laboratory studies of the interaction between Titan's tholins and simulated Titan's surface strongly suggests that many compounds of biological interest, including amino-acids, could be produced on Titan's surface. These new data will be presented together with a general description of Titan's astrobiological aspects as seen from Cassini-Huygens data. References F. Raulin.

    Tsukuba International Conference on Materials Science (TICMS) was held from 28th August to 6th September, 2013 for the celebration of 40th year anniversary of the University of Tsukuba. The conference was organized by the Division of Materials Science, in cooperation with the Graduate School of Pure and Applied Sciences, and Tsukuba Research Center for Interdisciplinary Materials Science. The purpose of the conference was to provide a unique forum for researchers and students working in various fields of materials science, which have been progressing so rapidly that no single society could cover. The conference consists of following seven workshops to cover various fields. The organizing committee believed that the conference gave all participants new insights into the widespread development of materials science and enhanced the circulation, among them, of information released at the conference. The organizers are grateful for the financial support from University of Tsukuba. This volume contains 25 selected papers from invited and contributed papers, all of which have been screened on the basis of the standard review process of the program committee. The editors express their thanks to those authors who contributed the papers published in this proceedings, which reflects the scientific value of the conference.

    2006-10-01

    In Fall 2003, the course ``Astrobiology'' has been introduced at the University of Texas at Arlington (UTA). This course is offered both at the graduate and undergraduate level, and is cross-listed between the Department of Physics, Department of Biology, and Department of Geology. The course is interdisciplinary in nature, encompassing selected topics of astronomy, stellar astrophysics, biochemistry, theoretical, evolutionary, and extremophile biology, geology, planetary science, and atmospheric physics. The outline of the course includes topics such as the nature and definition of life, origin and evolution of life on Earth, the search for life in the solar system, the possibility of life around different types of stars, including multiple stellar systems, stellar habitable zones, the search for extraterrestrial intelligence (SETI), and the Fermi paradox. ``Astrobiology'' is now offered the third time, and has enjoyed a steady increase in popularity. In my presentation, I will discuss the underlying goals, my teaching experience, problems and opportunities, including feed-back from students.

    Titan : • liquid water : permanently as a deep sub-surface ocean, and even episodically on the surface, • organic matter : in the internal structure, from chondritic materials, and in the atmosphere and on the surface, from the atmospheric organic chemistry • and energy : in the atmosphere (solar UV photons, energetic electrons from Saturn magnetosphere and cosmic rays) and, probably, in the environment of the sub-surface ocean (radioactive nuclei in the deep interior and tidal energy dissipation) as also supported by the likely presence of cryovolcanism on the surface Thus, it cannot be excluded that life may have emerged on or in Titan. In spite of the extreme conditions in this environment life may have been able to adapt and to persist. Many data are still expected from the Cassini-Huygens mission and future astrobiological exploration mission of Titan are now under consideration. Nevertheless, Titan already looks like another word, with an active prebiotic-like chemistry, but in the absence of permanent liquid water, on the surface: a natural laboratory for prebiotic-like chemistry.

    In recent years, science has become inextricably linked to the political process. As such, it is more important now than ever for science to forge a better relationship with politics, for the health of both science and society. To help meet this need, the American Geophysical Union (AGU) strives to engage its members, shape policy, and inform society about the excitement of Earth and space science and its role in developing solutions for the sustainability of the planet. In the spring of 2012, AGU held its inaugural Science Policy Conference in Washington, D.C. The goal of this new conference is to ensure diverse discussions and viewpoints on the challenges and opportunities of Earth and space science policy. The meeting brought together more than 300 scientists, policymakers, industry professionals, members of the press, and other stakeholders to discuss Arctic, oceans, natural resources, and natural hazards science as they relate to challenges impacting society. Sessions such as Hydraulic Fracturing, Mitigation and Resiliency to Severe Weather, Governance and Security in the Arctic, and Ocean Acidification are examples of some of the intriguing science policy issues addressed at the conference. The AGU Science Policy Conference will be an annual spring event in Washington, D.C.

  20. How can we teach astrobiology and survive?

    NASA Astrophysics Data System (ADS)

    Rodrigues, Telma; Carrapiço, Francisco

    2006-08-01

    Making science was and always will be a continuous challenge; however teaching science is a step forth. A good example is astrobiology. Defined as the scientific study of biological processes on Earth and beyond, it connects research in chemistry, physics, biology, geology, astronomy and planetary sciences. This interconnected scientific network allows us to visualize a new approach of the life's nature and its origins and development on Earth and elsewhere in the universe. With these goals, we wish to look within the nature of life, observing a new paradigm in the construction of the scientific knowledge. Teaching astrobiology is not an easy task. There are several constrains, such as treating and integrating diverse areas of knowledge and teaching a science that embraces so many questions presently unanswered and on which students have so many doubts and wrong pre-instructional beliefs. Another obstacle is the rapidly spreading of Intelligent Design, the new incarnation of creationism, which considers astrobiology as a danger for its policies, dogmas and philosophy. However, the principal barrier for teaching astrobiology is, without doubt, the difficulty to integrate this science in the curricular domain.

  22. FOREWORD: Proceedings of the Nordic Conference on Surface Science

    Pessa, V. M.; Nieminen, R. M.

    1983-01-01

    The present issue of Physica Scripta contains the Proceedings of the Nordic Conference on Surface Science. This meeting was held in Tampere, Finland 18-20 August, 1982. The original motivation for the conference was to bring together the various Nordic research groups engaged in surface science and related activities. However, soon after the initial announcement the conference attracted considerable interest also beyond the Nordic area, and it eventually obtained a truly international character: more than half of the 150 participants came from non-Nordic countries. At least to some extent this reflects the high international esteem of surface physics and chemistry in the Nordic area, which hosts some of the strongest research centers in this exciting and important branch of science. The conference provided an opportunity to exchange information in this rapidly moving field, to establish new contacts and strengthen old ones. It showed that there certainly is scope for increased collaboration between various groups, both within the Nordic countries and also more internationally. The opinion was expressed by several participants that this conference was a particularly successful one, both in scientific content and in format. It is the hope of the organizers of the Nordic Conference on Surface Science that this would serve as an incentive to consider having this kind of meetings on a more or less regular basis, as an established event in the Nordic surface science community. The cross-disciplinary nature of surface science is clearly reflected in these proceedings. The topics discussed range from those close to more traditional condensed matter spectroscopy through physical chemistry to biology. The formidable array of sophisticated techniques developed for surface investigations is given ample attention, but nevertheless the proceedings also show the trend towards more problem-oriented instead of technique-oriented emphasis. The proceedings are organized in accordance

    This report summarizes the organization, activities, and outcomes of Student Pugwash USA`s 1992 International Conference, Visions for a Sustainable World: A Conference on Science, Technology and Social Responsibility. The conference was held June 14--20, 1992 at Emory University, and brought together 94 students and over 65 experts from industry, academe, and government. The conference addressed issues ranging from global environmental cooperation to the social impacts of the Human Genome Project to minority concerns in the sciences. It provided a valuable forum for talented students and professionals to engage in critical dialogue on many interdisciplinary issues at the juncture of science, technology and society. The conference challenged students -- the world`s future scientists, engineers, and political leaders -- to think broadly about global problems and to devise policy options that are viable and innovative. The success of the conference in stimulating interest, understanding, and enthusiasm about interdisciplinary global issues is clearly evident from both the participants` feedback and their continued involvement in Student Pugwash USA programs. Six working groups met each morning. The working group themes included: environmental challenges for developing countries; energy options: their social and environmental impact; health care in developing countries; changing dynamics of peace and global security; educating for the socially responsible use of technology; ethics and the use of genetic information. The conference was specifically designed to include mechanisms for ensuring its long-term impact. Participants were encouraged to focus on their individual role in helping resolve global issues. This was achieved through each participant`s development of a Personal Plan of Action, a plan which mapped out activities the student could undertake after the conference to continue the dialogue and work towards the resolution of global and local problems.

  25. Astrobiology: Not Just Little Green Men

    Morrison, D.

    2004-05-01

    Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. This new (or at least newly-named) discipline responds to current opportunities to make significant progress on basic questions such as Where did we come from? Are we alone? Can we live on other planets? Every astronomer knows that these questions are frequently asked by the public, along with questions concerning the origin, dimensions, and ultimate fate of the universe itself. What makes curiosity about life in the universe so interesting is that we have some of the tools today to provide answers. Infrared and microwave telescopes characterize the complex chemistry that accompanies the birth of planetary systems. Concepts of planetary habitability emerge from exploring the extremes of life on Earth. We probe the nature of life itself through genetic and genomic insights into heredity and evolution. Our spacecraft are exploring Mars, Europa, and Titan, with the explicit goal of searching for evidence of life, past or present. And the discovery of exo-planetary systems greatly increases our opportunity to explore the diversity of planets and identify other habitable worlds. In addition to its interest as a research field, astrobiology provides an exciting medium for communicating science to students and the public. The questions studied by astrobiologists resonate with non-scientists. Astrobiology is also a popular subject for general-education college science courses. Its interdisciplinary techniques illustrate different ways of doing research such as exploration science versus hypothesis-driven science, or laboratory studies that are complementary to field work or historical science. All of these aspects make astrobiology a "cool" topic, and it will become even more exciting when we find evidence of life on Mars or discover earthlike planets beyond our solar system.

  27. A unifying concept for astrobiology

    NASA Astrophysics Data System (ADS)

    Chaisson, E. J.

    2003-04-01

    Evolution, broadly construed, has become a powerful unifying concept in much of science - not only in the biological evolution of plants and animals, but also in the physical evolution of stars and planets, and the cultural evolution of society and its many varied products. This paper (1) explores the bulk structure and functioning of open, non-equilibrium, thermodynamic systems relevant to the interdisciplinary field of astrobiology, (2) places the astrobiological landscape into an even larger, cosmological context, (3) defines life, complexity and evolution writ large, (4) claims that life depends ultimately on the expansion of the Universe and the flow of energy derived therefrom and (5) proposes a quantitative metric to characterize the rise of complexity throughout all of natural history. That metric is neither information nor negentropy, for these inveterate yet qualitative terms cannot be quantified, nor even defined, to everyone's satisfaction in today's scientific community. Rather, the newly proposed metric is normalized energy flow, a revision of a long-cherished term - energy - that is physically intuitive, well defined and readily measurable. All ordered systems = from rocky planets and shining stars, to buzzing bees and redwood trees - can be best judged empirically and uniformly by gauging the amount of energy acquired, stored and expressed by those systems. Appeals to anthropism are unnecessary to appreciate the impressive hierarchy of the cosmic evolutionary narrative, including a technological civilization that now embraces an energetics agenda designed to better understand, and perhaps to unify, all the natural sciences.

    Phillips, C. B.; Devore, E. K.

    2009-12-01

    The SETI Institute hosts a summer Astrobiology Research Experience for Undergraduates program for highly motivated students interested in astrobiology research. Students work with scientists at the SETI Institute and at the nearby NASA Ames Research Center on projects spanning the field of astrobiology from microbiology to planetary geology to astronomy and astrophysics. Each student is mentored by a scientist for his/her summer research project. As astrobiology is interdisciplinary, the first week includes a seminar series to provide a broad foundation in the field as the students begin their research projects. The 10-week program includes a week-long field trip to the SETI Institute’s Allen Telescope Array, located at the Hat Creek Radio Astronomy Observatory in Northern California, as well as a field experience at hydrothermal systems at nearby Lassen Volcanic National Park. Students also participate in local field trips to places like the California Academy of Sciences and other nearby locations of scientific interest, and attend seminars, lectures, and discussions on astrobiology. Students are also invited to attend events at nearby NASA Ames Research Center, which offers the opportunity to interact with other undergraduate and graduate students participating in NASA summer programs. At the end of the program, students write up and present their research projects, and mentors recommend some projects for submission to a national scientific conference, which the selected students will be funded to attend. The Astrobiology REU program emphasizes three main areas, which are listed in the table along with typical project themes. Each year, specific student research projects are described on the website, and students are asked to select the three that most interest them as a part of their applications. Applications are due in early February. Typically, 10 students apply for each available position. Students have been selected from colleges and universities

  1. Astrobiological complexity with probabilistic cellular automata.

    Vukotić, Branislav; Ćirković, Milan M

    2012-08-01

    The search for extraterrestrial life and intelligence constitutes one of the major endeavors in science, but has yet been quantitatively modeled only rarely and in a cursory and superficial fashion. We argue that probabilistic cellular automata (PCA) represent the best quantitative framework for modeling the astrobiological history of the Milky Way and its Galactic Habitable Zone. The relevant astrobiological parameters are to be modeled as the elements of the input probability matrix for the PCA kernel. With the underlying simplicity of the cellular automata constructs, this approach enables a quick analysis of large and ambiguous space of the input parameters. We perform a simple clustering analysis of typical astrobiological histories with "Copernican" choice of input parameters and discuss the relevant boundary conditions of practical importance for planning and guiding empirical astrobiological and SETI projects. In addition to showing how the present framework is adaptable to more complex situations and updated observational databases from current and near-future space missions, we demonstrate how numerical results could offer a cautious rationale for continuation of practical SETI searches.

  6. Astrobiology - The New Synthesis

    NASA Astrophysics Data System (ADS)

    Sik, A.; Simon, T.

    Background In connection with the complex planetology-education in Hungary [1] we have compiled an Astrobiology coursebook - as a base of its teaching in universities and perhaps in secondary schools as well. We tried to collect and assemble in a logical and thematical order the scientific breakthroughs of the last years, that made possible the fast improvement of astrobiology. The followings are a kind of summary of these. Introduction - The ultimate science Astrobiology is a young science, that search for the possibility, forms and places of extraterrestrial life. But it is not SETI, because do not search for intelligent life, just for living organisms, so SETI is a part of astrobiology. and an extremely important statement: we can search for life-forms that similar to terrestrial life in physiology so we can recognize it as life. Astrobiology is one of the most dynamical-developing sciences of the 21st century. To determine its boundaries is difficult because the complex nature of it: astrobiology melt into itself lot of other sciences, like a kind of ultimate science. The fundamental questions are very simple [2]: When, where and how converted the organic matter into life?; How does life evolve in the Universe?; Has it appeared on other planets?; How does it spread in time and space?; and What is the future of terrestrial life? However, trying to find the answers is quite difficult. So an astrobiologist has to be aware of the basics of astronomy, space research, earth and planetary sciences, and life sciences (mainly ecology, genetics, molecular and evolution biology). But it is not enough - the newest results of these at least as important as the basic knowledge. Part I. - Astro 1. Exoplanets 1995 was a particular year in astronomy: we have found the first planet out of the Solar System. Since that time the discovery of exoplanets progress fast: nowdays more than 80 examples are known and just 6 years passed [3]. The detailed analysis of these distant objects

    NASA Astrophysics Data System (ADS)

    Dick, Steven

    NASA's Astrobiology Roadmap, developed in 1998 by an interdisciplinary team of more than 150 individuals, recognizes ten science goals, 17 more specific science objectives, and four broad principles for the Astrobiology Program. Among the four operating principles, which emphasize multidisciplinarity, planetary stewardship and public outreach, is one that also recognizes broad societal interest for the implications of astrobiology, especially its extraterrestrial life component. Although several meetings ahve been convened in the past decade to discuss the implications of extraterrestrial intelligence, including NASA's own CASETI workshops in 1991-1992, none have surveyed the broader implications of astrobiology as now defined at NASA. In this paper we survey these societal questions raised by astrobiology, and then focus on those related to extraterrestrial life, and in particular how they might differ from SETI concerns already discussed. As we enter the new millennium, the necessity for interdisciplinary studies is increasingly recognized in academia, industry and government. Astrobiology provides an unprecedented opportunity to encourage the unity of knowledge, as recently proposed in E. O. Wilson's book Consilience: The Unity of Knowledge. It is incumbent on scientists to support research on the implications of their work, in particular large government-funded scientific projects. The deep insights such study may yield has been amply demonstrated by the Human Genome Project, among others.

  8. An Online Astrobiology Course for Teachers

    2002-06-01

    A continuing challenge for scientists is to keep K-12 teachers informed about new scientific developments. Over the past few years, this challenge has increased as new research findings have come from the field of astrobiology. In addition to trying to keep abreast of these new discoveries, K-12 teachers must also face the demands of the content and pedagogical goals imposed by state and national science education standards. Furthermore, many teachers lack the scientific content knowledge or training in current teaching methods to create their own activities or to implement appropriately new teaching materials designed to meet the standards. There is a clear need for special courses designed to increase the scientific knowledge of K-12 science teachers. In response to this need, the authors developed a suite of innovative, classroom-ready lessons for grades 5-12 that emphasize an active engagement instructional strategy and focus on the recent discoveries in the field of astrobiology. They further created a graduate-level, Internet-based distance-learning course for teachers to help them become familiar with these astrobiology concepts and to gain firsthand experience with the National Science Education Standards-based instructional strategies.

  10. Astrobiology: The Case for Venus

    NASA Technical Reports Server (NTRS)

    Landis, Geoffrey A.

    2003-01-01

    The scientific discipline of astrobiology addresses one of the most fundamental unanswered questions of science: are we alone? Is there life elsewhere in the universe, or is life unique to Earth? The field of astrobiology includes the study of the chemical precursors for life in the solar system; it also includes the search for both presently existing life and fossil signs of previously existing life elsewhere in our own solar system, as well as the search for life outside the solar system. Two of the promising environments within the solar system being currently considered are the surface of the planet Mars, and the hypothesized oceans underneath the ice covering the moon Europa. Both of these environments differ in several key ways from the environments where life is found on Earth; the Mars environment in most places too cold and at too low pressure for liquid water to be stable, and the sub-ice environment of Europa lacking an abundance of free energy in the form of sunlight. The only place in the solar system where we know that life exists today is the Earth. To look for life elsewhere in the solar system, one promising search strategy would be to find and study the environment in the solar system with conditions that are most similar to the environmental conditions where life thrives on the Earth. Specifically, we would like to study a location in the solar system with atmospheric pressure near one bar; temperature in the range where water is liquid, 0 to 100 C; abundant solar energy; and with the primary materials required for life, carbon, oxygen, nitrogen, and hydrogen, present. Other than the surface of the Earth, the only other place where these conditions exist is the atmosphere of Venus, at an altitude of about fifty kilometers above the surface.

    The search for life and its study is known as astrobiology. Conducting that search on other planets in our Solar System is a major goal of NASA and other space agencies, and a driving passion of the community of scientists and engineers around the world. We practice for that search in many ways, from exploring and studying extreme environments on Earth, to developing robots to go to other planets and help us look for any possible life that may be there or may have been there in the past. The unique challenges of space exploration make collaborations between robots and humans essential. The products of those collaborations will be novel and driven by the features of wholly new environments. For space and planetary environments that are intolerable for humans or where humans present an unacceptable risk to possible biologically sensitive sites, autonomous robots or telepresence offer excellent choices. The search for life signs on Mars fits within this category, especially in advance of human landed missions there, but also as assistants and tools once humans reach the Red Planet. For planetary destinations where we do not envision humans ever going in person, like bitterly cold icy moons, or ocean worlds with thick ice roofs that essentially make them planetary-sized ice caves, we will rely on robots alone to visit those environments for us and enable us to explore and understand any life that we may find there. Current generation robots are not quite ready for some of the tasks that we need them to do, so there are many opportunities for roboticists of the future to advance novel types of mobility, autonomy, and bio-inspired robotic designs to help us accomplish our astrobiological goals. We see an exciting partnership between robotics and astrobiology continually strengthening as we jointly pursue the quest to find extraterrestrial life.

    The Minority Institution Astrobiology Collaborative (MIAC) began working with the NASA Goddard Center for Astrobiology in 2003 to develop curriculum materials for high school chemistry and Earth science classes based on astrobiology concepts. The Astrobiology in Secondary Classrooms (ASC) modules emphasize interdisciplinary connections in astronomy, biology, chemistry, geoscience, physics, mathematics, and ethics through hands-on activities that address national educational standards. Field-testing of the Astrobiology in Secondary Classrooms materials occurred over three years in eight U.S. locations, each with populations that are underrepresented in the career fields of science, technology, engineering, and mathematics. Analysis of the educational research upon the high school students participating in the ASC project showed statistically significant increases in students' perceived knowledge and science reasoning. The curriculum is in its final stages, preparing for review to become a NASA educational product. PMID:22984874

    2014-01-01

    With the increasing number of medical schools in Nepal, there is an expected increase in the number of Nepalese physiologists. The first medical school was established in the 1970s. We report here about the first annual conference of Nepalese physiologists on 27-28 September 2013 organized by the Department of Clinical Physiology of the Nepalese Army Institute of Health Sciences (NAIHS) and Kathmandu University School of Medical Sciences (KUMS). Nepalese physiologists are trying to form their own physiological society. In this regard, NAIHS and KUMS have played an important role to bring physiologists from different parts of Nepal involved in teaching, learning, and research activities in medical schools. There were a number of foreign invitees (India, Israel, Italy, Japan, and Sweden). There were plenary presentations on the topics that are relevant in Nepal, e.g., high-altitude physiology and wilderness medicine. The final session of the conference was an open session meeting of Nepalese physiologists. There was an open interaction about establishing Nepalese Physiological Society. After much deliberation, there was an agreement to register the society in Kathmandu with the current ad hoc committee which will elect the first executive body of the society. PMID:24580838

    Plutonium Futures--The Science 2006 provided opportunities to examine present knowledge of the chemical and physical properties of plutonium and other actinides in complex media and materials; to discuss the current and emerging science (chemistry, physics, materials science, nuclear science, and environmental effects) of plutonium and actinides relevant to enhancing global nuclear security; and to exchange ideas. This international conference also provided a forum for illustrating and enhancing capabilities and interests, and assessing issues in these areas. U.S. and international scientists, engineers, faculty, and students from universities, national laboratories, and DOE's nuclear complex were encouraged to participate and make technical contributions. The Conference ran from Sunday, July 9th through Thursday, July 13th. A popular aspect of the conference was the opening tutorial session on Sunday afternoon intended for students and scientists new to the area of plutonium research. The tutorial was well attended by novices and veterans alike, and featured such diverse topics as; plutonium metallurgy, plutonium in the environment, and international arms control and nonproliferation. Two plenary lectures began each morning and each afternoon session and highlighted the breakout sessions on coordination/organometallic chemistry, solid-state physics, environmental chemistry, materials science, separations and reprocessing, advanced fuels and waste forms, phase transformations, solution and gas-phase chemistry, compounds and complexes, electronic structure and physical properties, and more. Chemistry Highlights--Among the many chemistry highlights presented in this proceedings are the overview of concepts and philosophies on inert nuclear fuel matrices and concerns about the ever-increasing amounts of minor actinides and plutonium generated in the fuel cycle. The various ideas involve multiple reduction schemes for these materials, suggesting fuels for 'burning' or

    Scientists are increasingly using Twitter as a tool for communicating science. Twitter can promote scholarly discussion, disseminate research rapidly, and extend and diversify the scope of audiences reached. However, scientists also caution that if Twitter does not accurately convey science due to the inherent brevity of this media, misinformation could cascade quickly through social media. Data on whether Twitter effectively communicates conservation science and the types of user groups receiving these tweets are lacking. To address these knowledge gaps, we examined live tweeting as a means of communicating conservation science at the 2013 International Congress for Conservation Biology (ICCB). We quantified and compared the user groups sending and reading live tweets. We also surveyed presenters to determine their intended audiences, which we compared with the actual audiences reached through live tweeting. We also asked presenters how effectively tweets conveyed their research findings. Twitter reached 14 more professional audience categories relative to those attending and live tweeting at ICCB. However, the groups often reached through live tweeting were not the presenters' intended audiences. Policy makers and government and non-governmental organizations were rarely reached (0%, 4%, and 6% of audience, respectively), despite the intent of the presenters. Plenary talks were tweeted about 6.9 times more than all other oral or poster presentations combined. Over half the presenters believed the tweets about their talks were effective. Ineffective tweets were perceived as vague or missing the presenters' main message. We recommend that presenters who want their science to be communicated accurately and broadly through Twitter should provide Twitter-friendly summaries that incorporate relevant hashtags and usernames. Our results suggest that Twitter can be used to effectively communicate speakers' findings to diverse audiences beyond conference walls. PMID

    A UC-HBCU grant is requested to assist undergraduate and masters level HBCU Interns to achieve their professional and academic goals by attending summer school classes at UCSD along with graduate students in the UCSD Astrobiology Studies program, and by also attending a NASA sponsored scientific meeting in San Diego on Astrobiology organized by NASA scientist Richard Hoover (the 14th in a sequence). Hoover has recently published a paper in the Journal of Cosmology claiming extraterrestrial life fossils in three meteorites. Students will attend a workshop to prepare research publications on Astrobiological Science for the Journal of Cosmology or equivalent refereed journal, mentored by UCSD faculty and graduate students as co-authors and referees, all committed to the several months of communication usually required to complete a publishable paper. The program is intended to provide pathways to graduate admissions in the broad range of science and engineering fields, and by exposure to fundamental science and engineering disciplines needed by Astrobiologists. A three year UC-HBCU Astrobiological Studies program is proposed: 2011, 2012 and 2013. Interns would be eligible to enter this program when they become advanced graduate students. A center of excellence in astrobiology is planned for UCSD similar to that Directed by Professor Wickramasinghe for many years with Fred Hoyle at Cardiff University, http://www.astrobiology.cf.ac.uk /chandra1.html. Professor Wickramasinghe's CV is attached as Appendix 1. Figures A2-1,2 of Appendix 2 compare Astrobiology timelines of modern fluid mechanical and astrobiological models of Gibson/Wickramasinghe/Schild of the Journal of Cosmology with standard NASA- CDMHC models. NASA support will be sought to support research and educational aspects of both initiatives. Overload teaching of up to two courses a year by UCSD faculty of key astrobiology courses at either UCSD or at HBCU campuses is authorized by recent guidelines of UCSD

    We present results from several projects in the new field of computational astrobiology, which is devoted to advancing our understanding of the origin, evolution and distribution of life in the Universe using theoretical and computational tools. We have developed a procedure for calculating long-range effects in molecular dynamics using a plane wave expansion of the electrostatic potential. This method is expected to be highly efficient for simulating biological systems on massively parallel supercomputers. We have perform genomics analysis on a family of actin binding proteins. We have performed quantum mechanical calculations on carbon nanotubes and nucleic acids, which simulations will allow us to investigate possible sources of organic material on the early earth. Finally, we have developed a model of protobiological chemistry using neural networks.

    We review the current state of knowledge concerning microbial extremophiles and comets and the potential significance of comets to Astrobiology. We model the thermal history of a cometary body, regarded as an assemblage of boulders, dust, ices and organics, as it approaches a perihelion distance of - IAU. The transfer of incident energy from sunlight into the interior leads to the melting of near surface ices, some under stable porous crust, providing possible habitats for a wide range of microorganisms. We provide data concerning new evidence for indigenous microfossils in CI meteorites, which may be the remains of extinct cometary cores. We discuss the dominant microbial communities of polar sea-ice, Antarctic ice sheet, and cryoconite environments as possible analogs for microbial ecosystems that may grow in sub-crustal pools or in ice/water films in comets.

    The first part of this talk will describe how infrared spectroscopic studies of interstellar space, combined with laboratory simulations of interstellar ice chemistry, have revealed the widespread presence of interstellar PAHs and the composition of interstellar ices, the building blocks of comets. The remainder of the presentation will focus on the photochemical evolution of these materials and astrobiology. Within a molecular cloud, and especially the presolar nebula, materials frozen into the ices are photoprocessed by ultraviolet light and produce more complex molecules. As these materials are the building blocks of comets and related to carbonaceous micrometeorites, they are likely to have been important sources of complex materials delivered to the early Earth and their composition may be related to the origin of life.

  8. Multispectral Microimager for Astrobiology

    Sellar, R. Glenn; Farmer, Jack D.; Kieta, Andrew; Huang, Julie

    2006-01-01

    A primary goal of the astrobiology program is the search for fossil records. The astrobiology exploration strategy calls for the location and return of samples indicative of environments conducive to life, and that best capture and preserve biomarkers. Successfully returning samples from environments conducive to life requires two primary capabilities: (1) in situ mapping of the mineralogy in order to determine whether the desired minerals are present; and (2) nondestructive screening of samples for additional in-situ testing and/or selection for return to laboratories for more in-depth examination. Two of the most powerful identification techniques are micro-imaging and visible/infrared spectroscopy. The design and test results are presented from a compact rugged instrument that combines micro-imaging and spectroscopic capability to provide in-situ analysis, mapping, and sample screening capabilities. Accurate reflectance spectra should be a measure of reflectance as a function of wavelength only. Other compact multispectral microimagers use separate LEDs (light-emitting diodes) for each wavelength and therefore vary the angles of illumination when changing wavelengths. When observing a specularly-reflecting sample, this produces grossly inaccurate spectra due to the variation in the angle of illumination. An advanced design and test results are presented for a multispectral microimager which demonstrates two key advances relative to previous LED-based microimagers: (i) acquisition of actual reflectance spectra in which the flux is a function of wavelength only, rather than a function of both wavelength and illumination geometry; and (ii) increase in the number of spectral bands to eight bands covering a spectral range of 468 to 975 nm.

    The program goal was to provide a hands-on astrobiology learning experience to high school students by introducing astrobiology and providing opportunities to conduct field and lab research with NASA scientists. The program sought to increase interest in interdisciplinary science, technology, engineering, math and related careers. Lassen Volcanic National Park (LVNP), Red Bluff High School and the Ames Team of the NASA Astrobiology Institute led the program. LVNP was selected because it shares aspects of volcanism with Mars and it hosts thermal springs with microbial mat communities. Students documented volcanic deposits, springs and microbial mats. They analyzed waters and sampled rocks, water and microorganisms. They cultured microorganisms and studied chemical reactions between rocks and simulated spring waters. Each student prepared a report to present data and discuss relationships between volcanic rocks and gases, spring waters and microbial mats. At a "graduation" event the students presented their findings to the Red Bluff community. They visited Ames Research Center to tour the facilities and learn about science and technology careers. To evaluate program impact, surveys were given to students after lectures, labs, fieldwork and discussions with Ames scientists. Students' work was scored using rubrics (labs, progress reports, final report, presentation). Students took pre/post tests on core astrobiology concepts. Parents, teachers, rangers, Ames staff and students completed end-of-year surveys on program impact. Several outcomes were documented. Students had a unique and highly valued learning experience with NASA scientists. They understood what scientists do through authentic scientific work, and what scientists are like as individuals. Students became knowledgeable about astrobiology and how it can be pursued in the lab and in the field. The students' interest increased markedly in astrobiology, interdisciplinary studies and science generally.

    It is unavoidable that the science of astrobiology will intersect with, and inevitably challenge, many deeply held beliefs. Exploration possibilities, particularly those that may include the discovery of extraterrestrial life, will continue to challenge us to reconsider our views of nature and our connection to the rest of the universe. As a scientific discipline, astrobiology works from the assumption that the origin and evolution of life can be accounted for by natural processes, that life could emerge naturally from the physical materials that make up the terrestrial planets. The search for life on other terrestrial planets is focused on “life as we know it.” The only life we currently know of is the life found on Earth, and for the scientific community the shared common ancestry of all Earth life, and its astounding diversity, is explained by the theory of evolution. The work of astrobiology, at its very core, is fueled by the theory of evolution. However, a survey by the Pew Forum on Religion and Public Life (2005) revealed that 42% of US adults believe that “life has existed in its present form since the beginning of time”. This answer persists nearly 150 years after the publication of Charles Darwin’s "On the Origin of the Species", the landmark work in which Darwin proposed that living things share common ancestors and have “descended with modification” from these ancestors through a process of natural selection . Perhaps even more distressing is the fact that these numbers have not changed in decades, despite the astounding advancements in science that have resulted over this same time period. How will these facts bear on the usefulness of astrobiology as a tool for encouraging a US public to share in the excitement of scientific discovery and be informed participants in a public dialogue concerning next steps? When people were asked “to identify the biggest influence on your thinking about how life developed,” the response chosen most

    One of the main goals of astrobiology is to understand the origin of cellular life. The most direct approach to this problem is to construct laboratory models of protocells. Such efforts, currently underway in the NASA Astrobiology Program, are accompanied by computational studies aimed at explaining self-organization of simple molecules into ordered structures that are capable of performing protocellular functions. Many of these functions, such as importing nutrients, capturing energy and responding to changes in the environment, are carried out by proteins bound to membranes. We use computer simulations to address the following questions about these proteins: (1) How do small proteins self-organize into ordered structures at water-membrane interfaces and insert into membranes? (2) How do peptides form membrane-spanning structures (e.g. channels)? (3) By what mechanisms do such structures perform their functions? The simulations are performed using the molecular dynamics method. In this method, Newton's equations of motion for each atom in the system are solved iteratively. At each time step, the forces exerted on each atom by the remaining atoms are evaluated by dividing them into two parts. Short-range forces are calculated in real space while long-range forces are evaluated in reciprocal space, using a particle-mesh algorithm which is of order O(NInN). With a time step of 2 femtoseconds, problems occurring on multi-nanosecond time scales (10(exp 6)-10(exp 8) time steps) are accessible. To address a broader range of problems, simulations need to be extended by three orders of magnitude, which requires algorithmic improvements and codes scalable to a large number of processors. Work in this direction is in progress. Two series of simulations are discussed. In one series, it is shown that nonpolar peptides, disordered in water, translocate to the nonpolar interior of the membrane and fold into helical structures (see Figure). Once in the membrane, the peptides

    With the present surge of interest in astrobiology and its emergence as a new scientific discipline in its own right, the role of a celebrated pioneer is all too often forgotten. There can be little doubt that the late Sir Fred Hoyle played a key part in relating astronomical phenomena to questions of life. One of his first contributions in this area was his introduction of the so-called anthropic principle to astronomy. By the late 1940's astronomers had worked out how the simplest chemical element Hydrogen could be converted into Helium in stars, thus providing the main energy source by which stars shine. The building of nuclei beyond Helium by stellar nuclear processes appeared difficult at the time because of instabilities in nuclei with atomic masses 5 and 8. Hoyle had the grand vision of making most if not all of the elements in the Periodic Table in stars. In the early 1950's Hoyle argued that by the very fact of our existence, the existence of life, the element Carbon had to be synthesised in quantity in stars. This could not happen, Hoyle concluded, unless the nucleus of Carbon possessed an energy level corresponding to a hitherto unknown excited state which he was able to calculate. This was necessary so that three Helium nuclei could combine first to form a Carbon nucleus in the excited state that subsequently decayed into the ground state. One of the major triumphs of Hoyle's Anthropic Principle was that his predicted excited state was subsequently discovered in the laboratory by Ward Whaling and Willy Fowler at Caltech. This discovery opened the door to a brand new discipline of Nuclear Astrophysics. In a seminal paper published in 1957, Hoyle together with Willy Fowler, Geoffrey and Margaret Burbidge showed that all the chemical elements needed for life C, N, O, P, Mg, Fe, S ... were made in stars. In a sense Hoyle's work in 1957 already provided the foundation stone for astrobiology. He showed that in essence we were made of stardust.

    In this review we explore aspects of the field of astrobiology from an astronomical viewpoint. We therefore focus on the origin of life in the context of planetary formation, with additional emphasis on tracing the most abundant volatile elements, C, H, O, and N that are used by life on Earth. We first explore the history of life on our planet and outline the current state of our knowledge regarding the delivery of the C, H, O, N elements to the Earth. We then discuss how astronomers track the gaseous and solid molecular carriers of these volatiles throughout the process of star and planet formation. It is now clear that the early stages of star formation fosters the creation of water and simple organic molecules with enrichments of heavy isotopes. These molecules are found as ice coatings on the solid materials that represent microscopic beginnings of terrestrial worlds. Based on the meteoritic and cometary record, the process of planet formation, and the local environment, lead to additional increases in organic complexity. The astronomical connections towards this stage are only now being directly made. Although the exact details are uncertain, it is likely that the birth process of star and planets likely leads to terrestrial worlds being born with abundant water and organics on the surface.

    Tremendous strides have been made in our understanding of interstellar material over the past twenty five years thanks to significant developments in observational astronomy and laboratory astrophysics. Twenty years ago the composition of interstellar dust was largely guessed at, the concept of ices in dense molecular clouds ignored, and the notion of large, abundant, gas phase, carbon-rich molecules widespread throughout the interstellar medium (ISM) considered impossible. Today the composition of interstellar dust is reasonably well understood. In molecular clouds, the birthplace of stars and planets, these cold dust particles are coated with mixed molecular ices whose composition is very well constrained. Lastly, the signature of carbon-rich polycyclic aromatic hydrocarbons (PAHs), shockingly large molecules by early interstellar chemistry standards, is widespread throughout the Universe. The first part of this talk will describe how infrared spectroscopic studies of interstellar space, combined with laboratory simulations of interstellar ice chemistry, have revealed the widespread presence of interstellar PAHs and the composition of interstellar ices, the building blocks of comets. The remainder of the presentation will focus on the photochemical evolution of these materials and astrobiology. Within a molecular cloud, and especially the presolar nebula, materials frozen into the ices are photoprocessed by ultraviolet light and produce more complex molecules. As these materials are the building blocks of comets and related to carbonaceous micrometeorites, they are likely to have been important sources of complex materials delivered to the early Earth and their composition may be related to the origin of life.

    2010-03-01

    This report documents the work of the Mid-Range Rover Science Analysis Group (MRR-SAG), which was assigned to formulate a concept for a potential rover mission that could be launched to Mars in 2018. Based on programmatic and engineering considerations as of April 2009, our deliberations assumed that the potential mission would use the Mars Science Laboratory (MSL) sky-crane landing system and include a single solar-powered rover. The mission would also have a targeting accuracy of approximately 7 km (semimajor axis landing ellipse), a mobility range of at least 10 km, and a lifetime on the martian surface of at least 1 Earth year. An additional key consideration, given recently declining budgets and cost growth issues with MSL, is that the proposed rover must have lower cost and cost risk than those of MSL--this is an essential consideration for the Mars Exploration Program Analysis Group (MEPAG). The MRR-SAG was asked to formulate a mission concept that would address two general objectives: (1) conduct high priority in situ science and (2) make concrete steps toward the potential return of samples to Earth. The proposed means of achieving these two goals while balancing the trade-offs between them are described here in detail. We propose the name Mars Astrobiology Explorer-Cacher(MAX-C) to reflect the dual purpose of this potential 2018 rover mission. PMID:20298148

    The AstroBiology Explorer (ABE) and the Astrobiology SPace InfraRed Explorer (ASPIRE) Mission Concepts are two missions designed to address the questions (1) "Where do we come from?" and (2) "Are we alone?" as outlined in NASA's Origins Program. Both concepts use infrared spectroscopy to explore the identity, abundance, and distribution of molecules of astrobiological importance throughout the Universe. The ABE mission's observational program is focused on investigating the evolution of ice and organics in all phases of the lifecycle of carbon in the universe, from stellar birth through stellar death and exogenous delivery of these compounds to planetary systems. The ASPIRE mission's observational program expands upon ABE's core mission and also addresses the role of silicates and gas-phase materials in interstellar organic chemistry. ABE (ASPIRE) achieves these goals using a highly sensitive, cryogenically-cooled telescope in an Earth drift-away heliocentric orbit, armed with a suite of infrared spectrometers that cover the 2.5-20 (40) micron spectral region at moderate spectral resolution ( R > 2000). ASPIRE's spectrometer complement also includes a high-resolution ( R > 25,000) module over the 4-8 micron spectral region. Both missions' target lists are chosen to observe a statistically significant sample of a large number of objects of varied types in support of the tasks outlined above. The ABE and ASPIRE mission lifetimes are designed to be 14 months and 3 years, respectively, both with significant cryogen and propellant lifetime margins to support an extended observing campaign. The ABE/ASPIRE Science Operations will be carried out at NASA's Ames Research Center, and the ABE/ASPIRE database will be archived at Caltech/IPAC.

    One of the main goals of astrobiology is to understand the origin of cellular life. In the absence of any record of the earliest ancestors of contemporary cells, protocells, the most direct way to test our understanding of their characteristics is to construct laboratory models of protocells. Such efforts, currently underway in the NASA Astrobiology Program, are accompanied by computational studies aimed at explaining self-organization of simple molecules into ordered structures and developing designs of molecules that are capable of performing protocellular functions. Many of these functions, such as importing nutrients, capturing and storing energy, and responding to changes in the environment, are carried out by proteins bound to membranes. We use computer simulations to address the following, questions about these proteins: (1) How do small proteins (peptides) organize themselves into ordered structures at water-membrane interfaces and insert into membranes?

  8. Astrobiology and Venus exploration

    NASA Astrophysics Data System (ADS)

    Grinspoon, David H.; Bullock, Mark A.

    For hundreds of years prior to the space age, Venus was considered among the most likely homes for extraterrestrial life. Since planetary exploration began, Venus has not been considered a promising target for Astrobiological exploration. However, Venus should be central to such an exploration program for several reasons. At present Venus is the only other Earth-sized terrestrial planet that we know of, and certainly the only one we will have the opportunity to explore in the foreseeable future. Understanding the divergence of Earth and Venus is central to understanding the limits of habitability in the inner regions of habitable zones around solar-type stars. Thus Venus presents us with a unique opportunity for putting the bulk properties, evolution and ongoing geochemical processes of Earth in a wider context. Many geological and meteorological processes otherwise active only on Earth at present are currently active on Venus. Active volcanism most likely affects the climate and chemical equilibrium state of the atmosphere and surface, and maintains the global cloud cover. Further, if we think beyond the specifics of a particular chemical system required to build complexity and heredity, we can ask what general properties a planet must possess in order to be considered a possible candidate for life. The answers might include an atmosphere with signs of flagrant chemical disequilibrium and active, internally driven cycling of volatile elements between the surface, atmosphere and interior. At present, the two planets we know of which possess these characteristics are Earth and Venus. Venus almost surely once had warm, habitable oceans. The evaporation of these oceans, and subsequent escape of hydrogen, most likely resulted in an oxygenated atmosphere. The duration of this phase is poorly understood, but during this time the terrestrial planets were not isolated. Rather, due to frequent impact transport, they represented a continuous environment for early microbial

    We are currently developing a teaching module on the NASA's Planetary Protection Program for UW-Parkside SENCER courses. SENCER stands for Science Education for New Civic Engagements and Responsibility. It is a national initiative of the National Science Foundation (NSF), now in its fifth year, to improve science education by teaching basic sciences through the complex public issues of the 21st century. The Planetary Protection Program is one such complex public issue. Teaching astrobiology and the NASA's goals via the Planetary Protection module within the SENCER courses seems to be a good formula to reach large number of students in an interesting and innovative way. We shall describe the module that we are developing. It will be launched on our web site titled "Astrobiology at Parkside" (http://oldweb.uwp.edu/academic/chemistry/kolb/organic_chemistry/, or go to Google and then to Vera Kolb Home Page), and thus will be available for teaching to all interested parties.

    The NASA Astrobiology Institute (NAI) was established as a means to advance the field of astrobiology by providing a multidisciplinary, multi-institution, science-directed program, executed by universities, research institutes, and NASA and other government laboratories. The scientific community and NASA defined the science content at several workshops as summarized in the NASA Astrobiology Roadmap. Teams were chosen nationwide, following the recommendations of external review groups, and the research program began in 1998. There are now 16 national Teams and five international affiliated and associated astrobiology institutions. The NAI has attracted an outstanding group of scientific groups and individuals. The Institute facilitates the involvement of the scientists in its scientific and management vision. Its goal is to support basic research and allow the scientists the freedom to select their projects and alter them as indicated by new research. Additional missions include the education of the public, the involvement of students who will be the astrobiologists of future generations, and the development of a culture of collaboration in NAI, a "virtual institute," spread across many sites nationally and internationally.

    Access to unweathered and uncontaminated samples of the least altered, oldest, sedimentary rocks is essential for understanding the early history of life on Earth and the environments in which it may have existed. For this reason, the NASA Astrobiology Institute (NAI) has embarked on two international programs, a series of Field Workshops aimed at making the most important surface samples available to investigators, and the Astrobiology Drilling Program (ADP), which serves to provide access to fresh subsurface samples when the scientific objectives require them. The Astrobiology Drilling Program commenced in Western Australia in 2003 with the initiation of its first project, the Archean Biosphere Drilling Project (ABDP). Funding for the ABDP came mainly from the Japanese Government through Kagoshima University and from NASA through the NAI Team at Pennsylvania State University, but significant technical and logistic support was provided by the Geological of Western Australia and, to a lesser extent, by the University of Western Australia. Six diamond drill cores totalling 1.4 km were obtained from astrobiologically important successions in the 3.3-3.5 Ga-old Pilbara Craton of northern Western Australia. Drilling in 2004 also occurred in Western Australia. The Deep Time Drilling Project (DTDP), a spin-off from the NAI's Mission to Early Earth Focus Group, completed one long hole, aimed mainly at fossil biomolecules (biomarkers) and other geochemical indicators of early life. The DTDP and the ABDP also jointly drilled two other important holes 2004, one through the oldest known erosion surface (and possible soil profile). The other intersected well-preserved middle Archean sediments. These efforts parallel other drilling initiatives within the wider astrobiological community that are taking place in Western Australia, South Africa, Spain, and arctic Canada. The ADP is managed by the NAI through a Steering Committee appointed by the NAI Director. Samples of cores

    Schultz, Greg

    In 1998, UCLA was selected as one of the 11 initial members (5 of which are universities) of the NASA Astrobiology Institute. Concurrently, UCLA implemented a brand new General Education cluster course, GE 70ABC: ``Evolution of the Cosmos and Life,'' which is unique for several reasons. It is (a) interdisciplinary, introducing students to both the life and physical sciences, (b) team-taught by 4 distinguished professors, and 4 advanced graduate teaching fellows, (c) offered for (150) freshmen students exclusively, and (d) a year-long sequence, incorporating lectures, laboratory/discussion sections, field trips, and in the spring quarter, small satellite seminars led by the individual instructors on topics radiating from the cluster theme. Further information about GE 70ABC can be found at the course website (http://www.ess.ucla.edu/Cluster_TOC.html) and the website for UCLA's GE cluster courses (http://www.college.ucla.edu/ge/clusters.htm). This poster will outline the GE 70 content, and describe some of the course's materials, activities, assessment, and student characteristics. Additionally, focus will be placed on the GE 70C seminar course component called ``Life In the Cosmos,'' designed and offered by the poster author for the Spring 1999 quarter. This seminar features a student-centered approach - with lecturing minimized and active learning a key objective - and addresses the extraterrestrial life debate from historical and cultural perspectives as well as the current scientific approaches in astrobiology/bioastronomy.

    The International Joint AIRAPT-22 & HPCJ-50 Conference was held in Odaiba, Tokyo, on 26-31 July 2009. About 480 scientists from 24 countries attended the conference and 464 papers, including 3 plenary lectures, 39 invited talks, and 156 oral presentations, were presented. It is my great pleasure to present this proceedings volume, which is based on the high quality scientific works presented at the conference. The International AIRAPT conference has been held every two years in various countries around the world since 1965, while High Pressure Conference of Japan (HPCJ) has been held annually since 1959 in various Japanese cities. Pressure is a fundamental parameter to control the property of matter. As a result, both AIRAPT and HPCJ have become highly multidisciplinary, and cover Physics, Chemistry, Materials Science, Earth and Planetary Sciences, Biosciences, Food Science, and Technology. Although each discipline has a unique target, they all have high-pressure research in common. This proceedings volume includes about 200 papers of state-of-the-art studies from numerous fields. I hope this proceedings volume provides excellent pieces of information in various fields to further advance high-pressure research.

    2002-01-01

    Astrobiology is the study of the origin, evolution and distribution of life in the universe. It provides a biological perspective to many areas of NASA research. It links such endeavors as the search for habitable planets, exploration missions to Mars and the outer Solar System, efforts to understand the origins and early evolution of life, and charting the potential of life to adapt to future challenges, both on Earth and in space. Astrobiology addresses the following three basic questions, which have been asked in some form for generations. How does life begin and evolve? Does life exist elsewhere in the universe? What is future of life on Earth and beyond? The NASA Astrobiology Roadmap provides guidance for research and technology development across several NASA Enterprises: Space Science, Earth Science, and the Human Exploration and Development of Space. The Roadmap is formulated in terms of eight Science Goals that outline key domains of investigation that might require perhaps decades of effort to consolidate. For each of these goals, Science Objectives outline more specific high priority near-term efforts for the next three to five years. These twenty objectives will be integrated with NASA strategic planning.

    Astrobiology is defined as the study of the living universe. This endeavor encompasses the use of space to understand life's origin, evolution, and destiny in the universe. Life's origin refers to understanding the origin of life in the context of the origin and diversity of planetary systems. Life's evolution refers to understanding how living systems have adapted to Earth's changing environment, to the all-pervasive force of gravity, and how they may adapt to environments beyond Earth. Life's destiny refers to making long-term human presence in space a reality, and laying the foundation for understanding and managing changes in Earth's environment. This lecture will explore the development of this field of inquiry, the science questions to be examined, and the mechanisms available for participation by the scientific community.

    2015-04-01

    A very warm welcome to all participants of the 9th Curtin University Technology, Science and Engineering (CUTSE) Conference 2014. This annual conference dates back to 2006 when the first Curtin University of Technology Science and Engineering (CUTSE) Conference was held in Curtin University, Miri Sarawak. CUTSE Conference was initially intended for Curtin's undergraduates such that they are able to experience the presentation of their work in a conference environment. As time passes and following the urge of knowledge dissemination, CUTSE Conference is hence open to public. This year the Department of Mechanical Engineering has been given the honour to organize the 9th CUTSE Conference. It has been a pleasure to watch CUTSE grow from strength to strength over the years. This year, our theme is "Discovering, Innovating and Engineering". We hope that it is in this spirit that CUTSE participants may align their respective work, such that we all aim for a greater and better implementation of "Discovering, Innovating and Engineering". The 9th CUTSE Conference 2014 is an excellent avenue for researchers, engineers, scientists, academicians, professionals from industry and students to share their research findings and initiate further collaborations in their respective fields. Parallel sessions in Mechanical, Electrical, Computer, Civil and Chemical engineering as well as the sciences will be hosted over a period of two days. Each year, the conference attracts participation from a number of countries in addition to Malaysia and Australia. In addition, student participants will get the opportunity to present their research projects and gain valuable feedback from industry professionals. This year the Conference will be organised by the Department of Mechanical Engineering of Curtin Sarawak's School of Engineering and Science in collaboration with The Institute of Engineers Malaysia, Miri Branch. On behalf of the organizing committee, I would like to thank this year

    2012-05-01

    The SETI Institute and San Jose State University (SJSU) have begun a partnership (URSA: Undergraduate Research at the SETI Institute in Astrobiology) in which undergraduate science and engineering majors from SJSU participate in research at the SETI Institute during the academic year. We are currently in our second year of the three-year NASA-funded grant. The goal of this program is to expose future scientists, engineers and educators to the science of astrobiology and to NASA in general, and by so doing, to prepare them for the transition to their future career in the Silicon Valley or beyond. The URSA students are mentored by a SETI Institute scientist who conducts research at the SETI Institute headquarters or nearby at NASA Ames Research Center. The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach. Its mission is to explore, understand and explain the origin, nature and prevalence of life in the universe. SJSU is a large urban public university that serves the greater Silicon Valley area in California. Students at SJSU come from diverse ethnic, cultural and socioeconomic backgrounds. Many of them face financial pressures that force them to pursue part-time work. URSA students are paid to work for 10 hours/week during the academic year, and also participate in monthly group meetings where they practice their presentation skills and discuss future plans. We encourage underserved and underrepresented students, including women, minority, and those who are the first in their family to go to college, to apply to the URSA program and provide ongoing mentoring and support as needed. While preparing students for graduate school is not a primary goal, some of our students have gone on to MS or PhD programs or plan to do so. The URSA program is funded by NASA EPOESS.

    The Astrobiology Habitable Environments Database (AHED) is a central, high quality, long-term searchable repository for archiving and collaborative sharing of astrobiologically relevant data, including, morphological, textural and contextural images, chemical, biochemical, isotopic, sequencing, and mineralogical information. The aim of AHED is to foster long-term innovative research by supporting integration and analysis of diverse datasets in order to: 1) help understand and interpret planetary geology; 2) identify and characterize habitable environments and pre-biotic/biotic processes; 3) interpret returned data from present and past missions; 4) provide a citable database of NASA-funded published and unpublished data (after an agreed-upon embargo period). AHED uses the online open-source software "The Open Data Repository's Data Publisher" (ODR - http://www.opendatarepository.org) [1], which provides a user-friendly interface that research teams or individual scientists can use to design, populate and manage their own database according to the characteristics of their data and the need to share data with collaborators or the broader scientific community. This platform can be also used as a laboratory notebook. The database will have the capability to import and export in a variety of standard formats. Advanced graphics will be implemented including 3D graphing, multi-axis graphs, error bars, and similar scientific data functions together with advanced online tools for data analysis (e. g. the statistical package, R). A permissions system will be put in place so that as data are being actively collected and interpreted, they will remain proprietary. A citation system will allow research data to be used and appropriately referenced by other researchers after the data are made public. This project is supported by the Science-Enabling Research Activity (SERA) and NASA NNX11AP82A, Mars Science Laboratory Investigations. [1] Nate et al. (2015) AGU, submitted.

  15. Critical issues in the history, philosophy, and sociology of astrobiology.

    Fifty years after serious scientific research began in the field of exobiology, and forty years after serious historical research began on the subject of extraterrestrial life, this paper identifies and examines some of the most important issues in the history, philosophy, and sociology of what is today known as astrobiology. As in the philosophy of science in general, and in the philosophies of particular sciences, critical issues in the philosophy and sociology of astrobiology are both stimulated and illuminated by history. Among those issues are (1) epistemological issues such as the status of astrobiology as a science, the problematic nature of evidence and inference, and the limits of science; (2) metaphysical/scientific issues, including the question of defining the fundamental concepts of life, mind, intelligence, and culture in a universal context; the role of contingency and necessity in the origin of these fundamental phenomena; and whether or not the universe is in some sense fine-tuned for life and perhaps biocentric; (3) societal issues such as the theological, ethical, and worldview impacts of the discovery of microbial or intelligent life; and the question of whether the search for extraterrestrial life should be pursued at all, and with what precautions; and (4) issues related to the sociology of scientific knowledge, including the diverse attitudes and assumptions of different scientific communities and different cultures to the problem of life beyond Earth, the public "will to believe," and the formation of the discipline of astrobiology. All these overlapping issues are framed by the concept of cosmic evolution-the 13.7 billion year Master Narrative of the Universe-which may result in a physical, biological, or postbiological universe and determine the long-term destiny of humanity.

    Kolb, Vera M.

    2015-09-01

    We present some recent developments in philosophy of astrobiology which illustrate usefulness of philosophy to astrobiology. We cover applications of Aristotelian views to definition of life, of Priest's dialetheism to the question if viruses are alive, and various thought experiments in regard to these and other astrobiology issues. Thought experiments about the survival of life in the Solar system and about the role of viruses at the beginning and towards the end of life are also described.

  17. Astrobiological Molecularly Imprinted Polymer Sensors

    2005-12-01

    Development of Molecularly Imprinted Polymer (MIP) sensors for astrobiology is intended to provide a new class of microlaboratory sensors compatible with other life or biomarker detection. Molecular imprinting is a process for making selective binding sites in synthetic polymers. The process may be approached by designing the recognition site or by simply choosing monomers that may have favorable interactions with the imprinting molecule. We are working to apply this methodology to astrobiology for development of a reliable, low cost, low mass, low power consumption sensor technology for quantitative in-situ analysis of biochemistry, biomarkers, and other indicators of astrobiological importance. Specific goals of the project are: 1) To develop a general methodology and specific methods for MIP-based sensor construction. The overall methodology will guide procedures for design and testing of any desired sensor. Specific methods will be applied to key families and specific species of astrobiological interest, i.e., alkanes (and Polycyclic aromatic hydrocarbons - PAHs), amino acids, steroids, and hopanes; 2) To construct and characterize the general family and specific species sensors. We will test for accuracy, precision, interferences, and limitations of the sensor against blanks, standards, and known terrestrial biological environment samples. Additional testing will determine sturdiness and longevity of sensors after exposure to transit conditions (launch and space environment), and at potential target environments (pressure, temperature, pH, etc.); and 3) To construct and demonstrate the combination of multiple sensors into a viable prototype instrument, and roadmap the expansion of potential instrument capabilities and exploration of the ultimate environmental limitations of the technology, and the necessary changes and additions to create a mission-ready instrument. Initial work has resulted successful detection of aqueous alanine (D and L) with simple MIP

INST2014 was held in August 2014 and hosted by Thailand Institute of Nuclear Technology (TINT). The theme was "Driving the future with nuclear technology". The conference working language was English. The proceedings were peer reviewed and considered for publication. The topics covered in the conference were: • Agricultural and food applications [AGR] • Environmental applications [ENV] • Radiation processing and industrial applications [IND] • Medical and nutritional applications [MED] • Nuclear physics and engineering [PHY] • Nuclear and radiation safety [SAF] • Other related topics [OTH] • Device and instrument presentation [DEV] Awards for outstanding oral and poster presentations will be given to qualified students who present their work during the conference.

  20. Perspectives of women of color in science-based education and careers. Summary of the conference on diversity in science

    SciTech Connect

    1998-12-01

    Research on inequality or stratification in science and engineering tends to concentrate on black/white or male/female difference; very few studies have discussions of both race and gender. Consequently, very little is known about the exact course that women of color take in science-based education and employment or about the course that steers them out of science-based careers. Questions abound: What are the environmental factors that affect the choices in education and science-based careers of women of color? What has influenced women of color who currently are in science-based careers? Is critical mass important and, if so, what are the keys to increasing it? What recommendations can be made to colleges and universities, faculty members, employers, the federal government, women of color themselves, and to improve the conditions and numbers of women of color in science-based careers? These questions prompted the National Research Council`s Committee on Women in Science and Engineering (CWSE) to convene a conference on Diversity in Science: Perspectives on the Retention of Minority Women in Science, Engineering, and Health-Care Professions, held on October 21--23, 1995. Confronting the problem of the lack of knowledge about the journey of women of color in science-based education and career, the conference offered opportunities for these women to describe the paths that they have taken and to identify strategies for success. Their perspectives ground this report. For purposes of this document, women of color include women in the following racial or ethnic groups: Hispanics, African-Americans, Asian and Pacific Islanders, and American Indians and Alaskan Natives. Science-based careers include those in the physical sciences and mathematics, life sciences, social sciences, and engineering.

    of 100μL from 1-10 mL of aqueous sample extract. The selective desorption process involves the derivatization of target analytes in the liquid state which acts to sequester these compounds by reducing their affinity towards the scavenger material. These processes show potential for a single step protocol for the purification of aqueous soil extracts and offer concentration factors of 10-100. These inline processing methods will help address problems of insufficient detection limits for organic detection on Mars and allow for integration as a module within future aqueous in situ flight instruments.

    Crawford, Ian A

    2010-01-01

    An ambitious program of human space exploration, such as that envisaged in the Global Exploration Strategy and considered in the Augustine Commission report, will help advance the core aims of astrobiology in multiple ways. In particular, a human exploration program will confer significant benefits in the following areas: (i) the exploitation of the lunar geological record to elucidate conditions on early Earth; (ii) the detailed study of near-Earth objects for clues relating to the formation of the Solar System; (iii) the search for evidence of past or present life on Mars; (iv) the provision of a heavy-lift launch capacity that will facilitate exploration of the outer Solar System; and (v) the construction and maintenance of sophisticated space-based astronomical tools for the study of extrasolar planetary systems. In all these areas a human presence in space, and especially on planetary surfaces, will yield a net scientific benefit over what can plausibly be achieved by autonomous robotic systems. A number of policy implications follow from these conclusions, which are also briefly considered. PMID:20735249

  9. Systems astrobiology for a reliable biomarker on exo-worlds

    NASA Astrophysics Data System (ADS)

    Chela Flores, Julian

    2013-04-01

    Although astrobiology is a science midway between biology and astrophysics, it has surprisingly remained largely disconnected from recent trends in certain branches of both of these disciplines. Aiming at discovering how systems properties emerge has proved valuable in chemistry and in biology and should also yield insights into astrobiology. This is feasible since new large data banks in the case of astrobiology are of a geophysical/astronomical kind, rather than the also large molecular biology data that are used for questions related firstly, to genetics in a systems context and secondly, to biochemistry. The application of systems biology is illustrated for our own planetary system, where 3 Earth-like planets are within the habitable zone of a G2V star and where the process of photosynthesis has led to a single oxygenic atmosphere that was triggered during the Great Oxidation Event some 2,5 billion years before the present. The significance of the biogenic origin of a considerable fraction of our atmosphere has been discussed earlier (Kiang et al., 2007). Bonding of O2 ensures that it is stable enough to accumulate in a world's atmosphere if triggered by a living process. The reduction of F and Cl deliver energy release per e+-transfer, but unlike O2 the weaker bonding properties inhibit large atmospheric accumulation (Catling et al., 2005). The evolution of O2-producing photosynthesis is very likely on exo-worlds (Wolstencroft and Raven, 2002). With our simplifying assumption of evolutionary convergence, we show how to probe for a reliable biomarker in the exo-atmospheres of planets, or their satellites, orbiting stars of different luminosities and ages (Chela-Flores, 2013). We treat the living process as a system of exo-environments capable of radically modifying their geology and atmospheres, both for exo-planets, and especially for exo-moons, the presence of which can be extracted from the Kepler data (Kipping et al., 2012). What we are learning about the

    2012-07-01

    The 23rd AIRAPT International Conference on High Pressure Science and Technology was held at Bhabha Atomic Research Centre, Mumbai, from 25-30 September 2011. This conference is part of the series of AIRAPT International Conferences which are held biennially. AIRAPT is an acronym for the French title which translates as 'International Association for the Advancement of High Pressure Science and Technology'. This was the second time the AIRAPT Conference was organized in India. The first was held 20 years ago at the National Aeronautical Laboratory, Bangalore in 1991. The 23rd Conference covered many important topics in the area of both static and dynamic high pressures including theoretical and experimental investigations on the response of materials under high pressures, new developments using neutron and synchrotron sources, investigations on superconductivity under high pressure, studies of geophysical and planetary sciences, biosciences, and the synthesis of new materials. The conference program included Bridgman award lecture, Jemieson award lecture, seven plenary talks, 85 invited talks, 83 oral presentations and about 195 posters. In all there were 372 presentations. 285 scientists from 19 countries participated in the conference. The countries represented included Austria, Canada, China, Estonia, France, Germany, India, Israel, Italy, Japan, Nepal, New Zealand, Poland, Russia, South Korea, Spain, Sweden, Switzerland, Turkey, UK, Ukraine and USA. Many new developments were presented, for example, measurement techniques using the new generation synchrotron sources, more powerful neutron sources and much brighter laser sources; integration of gas-gun with synchrotron source; the achievement of multi-megabar pressures in shock-less dynamic compressions; and capabilities to synthesize centimeter size diamonds with better quality. All these developments have opened up new opportunities for understanding the physics of materials under high pressures. I would like

    Each of the 11 lead members of NASA's Astrobiology Institute has a specific mission. According to Hiroshi Ohmoto, director of Penn State s Astrobiology Research Center, Here we are mainly concerned with the origin of life and the evolution and extinction of important organisms. These include bacteria that live on methane, cyanobacteria (the inventors of photosynthesis), eukaryotes (a big category, covering anything with a nucleus, from single-celled organisms to humans), land-dwelling organisms, and early animals. Penn State astrobiologists are studying the environment before there was life on Earth, the origin of oxygen in the atmosphere, the chemical and thermal structures of oceans, and the role of metals in the evolution of life. Overall, they want to understand the connection between changes in environment and changes in life forms in the early Earth. PSARC offers research assistantships for graduate and undergraduate students, fellowships for graduate students and post-doctoral fellows, and an undergraduate minor in astrobiology. The minor covers 18 credits in earth sciences, geochemistry, geophysics, astronomy, biology, biochemistry, meteorology, and microbiology. The goal, says Ohmoto, is to teach students to critically evaluate claims related to this field that they encounter well after their college education has ended. Under a scanning electron microscope, Martian meteorite ALH84001 yields tube-like structures that look a lot like remnants of Earthly bacteria except smaller by a factor of ten.

    In order to avoid the technological constraints that prevent the performance of experiments in other planets, Astrobiology research implies the development of models that simulate the conditions present in outer space or in planetary bodies. Extremophile organisms, like lichens have been widely studied in Astrobiology due to their high resistance to extremely harsh envi-ronments(5). The vagrant lichen species, Aspicilia fruticulosa lives detached from the substrate, and has a coralloid thalli up to 2.5 cm, which provides a very compact internal structure(6). This species typically grows in deserts and arid areas. Its resistance has been tested several times and amazing results about their vitality have been obtained. Two main experiments have been per-formed: 1. LITHOPANSPERMIA experiment(1): Integrated on board of BIOPAN (multi-user exposure facility, designed for exobiology, radiation biology, radiation dosimetry and material science investigations in space (http://www.spaceflight.esa.int/users/index.cfm?act=default.pagelevel=11p foton-next-pay-Bpan) launched on the Foton M3 satellite in September 2007); the resistance of this lichen species to the combination of the following space conditions during 10 days was tested: Ultraviolet (UV) extraterrestrial radiation, Mars UV-climate, UV-B radiation and Photosynthetically Active Radiation (PAR), microgravity, space vacuum of 1x10-6 mbar and extreme temperatures ranging from -23o C to +16o C. After the flight, the samples were revital-ized for a 72h period in a climatic chamber before taking measurements of their photosynthetic activity with a Mini-PAM fluorometer (Heinz Walz GmbH) as described by R. de la Torre et al. 2007b (2). The results showed that the samples exposed to space environment except solar UV radiation, reached a 76.5-1002. A step further on these investigations was carried out in order to study how the viability of this lichen species were affected by a combination of different sim-ulated martian

    Astrobiology is an interdisciplinary scientific field not only focused on the search of extraterrestrial life, but also on deciphering the key environmental parameters that have enabled the emergence of life on Earth. Understanding these physical and chemical parameters is fundamental knowledge necessary not only for discovering life or signs of life on other planets, but also for understanding our own terrestrial environment. Therefore, astrobiology pushes us to combine different perspectives such as the conditions on the primitive Earth, the physicochemical limits of life, exploration of habitable environments in the Solar System, and the search for signatures of life in exoplanets. Chemists, biologists, geologists, planetologists and astrophysicists are contributing extensively to this interdisciplinary research field. From 2011 to 2014, the European Space Agency (ESA) had the initiative to gather a Topical Team of interdisciplinary scientists focused on astrobiology to review the profound transformations in the field that have occurred since the beginning of the new century. The present paper is an interdisciplinary review of current research in astrobiology, covering the major advances and main outlooks in the field. The following subjects will be reviewed and most recent discoveries will be highlighted: the new understanding of planetary system formation including the specificity of the Earth among the diversity of planets, the origin of water on Earth and its unique combined properties among solvents for the emergence of life, the idea that the Earth could have been habitable during the Hadean Era, the inventory of endogenous and exogenous sources of organic matter and new concepts about how chemistry could evolve towards biological molecules and biological systems. In addition, many new findings show the remarkable potential life has for adaptation and survival in extreme environments. All those results from different fields of science are guiding our

    2015-12-01

    IOP Conference Series: Materials Science and Engineering is publishing a volume of conference proceedings that contains a selection of papers presented at the 4th Global Conference on Materials Science and Engineering (CMSE 2015), which is an annual event that started in 2012. CMSE 2015, technically supported by the Institute of Applied Physics and Materials Engineering of University of Macau, organized by Wuhan Advance Materials Society, was successfully held at the University of Macau-new campus located on Hengqin Island from August 3rd-6th, 2015. It aims to bring together leading academic scientists, researchers and scholars to exchange and share their experience and research results on all aspects of Materials Science and Engineering, and to discuss the practical challenges encountered and the solutions adopted. Macau, one of the two special administrative regions of the People's Republic of China, where East meets West, turned out to be an ideal meeting place for domestic and overseas participants of this annual international conference. The conference program included keynote presentations, special sessions, oral and poster contributions. From several hundred submissions, 52 of the most promising and mainstream, IOP-relevant, contributions were included in this volume. The submissions present original ideas or results of general significance, supported by clear reasoning, compelling evidence and methods, theories and practices relevant to the research. The authors state clearly the problems and the significance of their research to theory and practice. Being a successful conference, this event gathered more than 200 qualified and high-level researchers and experts from over 40 countries, including 10 keynote speakers from 6 countries, which created a good platform for worldwide researchers and engineers to enjoy the academic communication. Taking advantage of this opportunity, we would like to thank all participants of this conference, and particularly the

    The conference sprang from discussions on the current climate that women face in science, mathematics, engineering, and technology. The conference (and this document) is a beginning, not a culmination, of women`s learning leadership skills. Conferees were active, articulate, energetic, and ready to learn leadership qualities, some of which seem universal, others that appear to require skills in specific fields. After the introduction, the workshops and presentations are arranged under vision and direction, barriers, alignment and communication, and motivation and inspiration. Some statistics are presented on women degrees and employment in various fields.

    AstRoMap (Astrobiology and Planetary Exploration Road Mapping) is a funded project formulated in the 5th Call of the European Commission FP7 framework. The main objectives of the AstRoMap are: 1. Identify the main astrobiology issues to be addressed by Europe in the next decades in relation with space exploration 2. Identify potential mission concepts that would allow addressing these issues 3. Identify the technology developments required to enable these missions 4. Provide a prioritized roadmap integrating science and technology activities as well as ground-based approach 5. Map scientific knowledge related to astrobiology in Europe To reach those objectives, AstRoMap is executed within the following steps: 1. Community consultation. In order to map the European astrobiology landscape and to provide a collaborative networking platform for this community, the AstRoMap project hosts a database of scientists (European and beyond) interested in astrobiology and planetary exploration (see: http://www.astromap.eu/database.html). It reflects the demography and the research and teaching activities of the astrobiology community, as well as their professional profiles and involvement in astrobiology projects. Considering future aspects of astrobiology in Europe, the need for more astrobiology-dedicated funding programmes at the EU level, especially for cross-disciplinary groups, was stressed. This might eventually lead to the creation of a European laboratory of Astrobiology, or even of a European Astrobiology Institute. 2. Workshops organisation. On the basis of the feedbacks from the community consultation, the potential participants and interesting topics are being identified to take part in the following workshops: 1-. Origin of organic compounds, steps to life; 2. Physico-chemical boundary conditions for habitability 3. Biosignatures as facilitating life detection 4. Origin of the Solar system 3.

  12. Longitudinal effects of college type and selectivity on degrees conferred upon undergraduate females in physical science, life science, math and computer science, and social science

    NASA Astrophysics Data System (ADS)

    Stevens, Stacy Mckimm

    There has been much research to suggest that a single-sex college experience for female undergraduate students can increase self-confidence and leadership ability during the college years and beyond. The results of previous studies also suggest that these students achieve in the workforce and enter graduate school at higher rates than their female peers graduating from coeducational institutions. However, some researchers have questioned these findings, suggesting that it is the selectivity level of the colleges rather than the comprised gender of the students that causes these differences. The purpose of this study was to justify the continuation of single-sex educational opportunities for females at the post-secondary level by examining the effects that college selectivity, college type, and time have on the rate of undergraduate females pursuing majors in non-traditional fields. The study examined the percentage of physical science, life science, math and computer science, and social science degrees conferred upon females graduating from women's colleges from 1985-2001, as compared to those at comparable coeducational colleges. Sampling for this study consisted of 42 liberal arts women's (n = 21) and coeducational (n = 21) colleges. Variables included the type of college, the selectivity level of the college, and the effect of time on the percentage of female graduates. Doubly multivariate repeated measures analysis of variance testing revealed significant main effects for college selectivity on social science graduates, and time on both life science and math and computer science graduates. Significant interaction was also found between the college type and time on social science graduates, as well as the college type, selectivity level, and time on math and computer science graduates. Implications of the results and suggestions for further research are discussed.

  13. The International Journal of Astrobiology

    Wynn-Williams, David D.

    2002-01-01

    The launch of a new journal is appropriately like a space mission. It is the result of a scientific need, the inspiration of a group of committed scientists and technologists, a series of draft proposals, an approved mission protocol, and a launch. Today is the launch day for a journal whose remit has only recently consolidated from diverse disciplines. Cambridge University Press has an international reputation for astronomy. To this we add extreme biology and its associated environmental research to integrate astrobiology as: 'the study of the origin, evolution, adaptation and distribution of past and present life in the Universe'. Astrobiology has three main themes: (1) Origin, evolution and limits of life on Earth; (2) Future of life, both on Earth and elsewhere; (3) Search for habitats, biomolecules and life in the Solar System and elsewhere. These fundamental concepts require the integration of various disciplines, including biology (especially microbiology), chemistry, geology, palaeontology, and the physics of atmospheres, planets and stars. We must also keep our minds wide open about the nature and limits of life. We can safely assume a carbon-based system within Solar Systems as we know them, but our concept of habitable zones expands yearly. We were taught that only the spores of certain bacilli could survive temperatures above the boiling point of water, and yet we now know that the deep-sea vent microbe Pyrolobus can survive an hour at 121 °C, which is the temperature used for sterilising medical instruments. We know of cyanobacteria which can not only live inside deep-frozen Antarctic rocks but also survive on roof-tops in Jerusalem at 80 °C. The bacterium Deinococcus radiodurans tolerates lethal doses of nuclear radiation, and cyanobacteria inside Antarctic desert sandstone receive so little moisture that their carbon turnover time (from its fixation by photosynthesis to its release as carbon dioxide during respiration) is 10,000 years. Life is

    The American Geophysical Union hosted a Chapman Conference on Communicating Climate Science at Snow Mountain Ranch, Granby, Colorado, June 8-13, 2013. The goal of the Chapman Conference was to bring together scholars, social scientists and journalists to discuss the history, and more importantly, the present and future of climate change communication. We met to evaluate our current and needed communication capacity, and to develop ways and means to convey advances in the understanding of climate science. Delegates discussed and presented methods and capacity to communicate to policymakers, the media, and society. Our focus was on the efficacy of scientific communication, on improving communication practices, and on building collaborations spawned at the conference, and beyond. The Chapman was a success. Close to 150 of us gathered high in the Colorado Rockies to share almost 100 presentations and nearly 10 hours of group discussions focused on ways and means to better bring the climate change message to society, to educators and policymakers in North America and around the world. This presentation will focus on the outcomes of the Chapman Climate Change Communication Conference; the conclusions of the delegate community; and directions forward.

    This is an editorial report on the outcomes of an international conference sponsored by a grant from the National Science Foundation (NSF) (REESE-1205273) to the School of Education at Boston University and the Center for Philosophy and History of Science at Boston University for a conference titled: How Can the History and Philosophy of Science Contribute to Contemporary US Science Teaching? The presentations of the conference speakers and the reports of the working groups are reviewed. Multiple themes emerged for K-16 education from the perspective of the history and philosophy of science. Key ones were that: students need to understand that central to science is argumentation, criticism, and analysis; students should be educated to appreciate science as part of our culture; students should be educated to be science literate; what is meant by the nature of science as discussed in much of the science education literature must be broadened to accommodate a science literacy that includes preparation for socioscientific issues; teaching for science literacy requires the development of new assessment tools; and, it is difficult to change what science teachers do in their classrooms. The principal conclusions drawn by the editors are that: to prepare students to be citizens in a participatory democracy, science education must be embedded in a liberal arts education; science teachers alone cannot be expected to prepare students to be scientifically literate; and, to educate students for scientific literacy will require a new curriculum that is coordinated across the humanities, history/social studies, and science classrooms.

    In March 2007, the Mars Exploration Program Analysis Group (MEPAG) chartered the Human Exploration of Mars Science Analysis Group (HEM-SAG), co-chaired by J. B. Garvin and J. S. Levine and consisting of about 30 Mars scientists from the U.S. and Europe. HEM-SAG was one of a half dozen teams charted by NASA to consider the human exploration of Mars. Other teams included: Mars Entry, Descent and Landing, Human Health and Performance, Flight and Surface Systems, and Heliospheric/Astrophysics. The results of these Mars teams and the development of an architecture for the human exploration of Mars were summarized in two recent publications: Human Exploration of Mars Design Reference Architecture 5.0, NASA Special Publication-2009-566 (B. G. Drake, Editor), 100 pages, July 2009 and Human Exploration of Mars Design Reference Architecture 5.0, NASA Special Publication-2009-566 Addendum (B. G. Drake, Editor), 406 pages, July 2009. This presentation summarizes the HEM-SAG conclusions on astrobiology and the search for life on Mars by humans.

    Abstract The European AstRoMap project (supported by the European Commission Seventh Framework Programme) surveyed the state of the art of astrobiology in Europe and beyond and produced the first European roadmap for astrobiology research. In the context of this roadmap, astrobiology is understood as the study of the origin, evolution, and distribution of life in the context of cosmic evolution; this includes habitability in the Solar System and beyond. The AstRoMap Roadmap identifies five research topics, specifies several key scientific objectives for each topic, and suggests ways to achieve all the objectives. The five AstRoMap Research Topics are • Research Topic 1: Origin and Evolution of Planetary Systems• Research Topic 2: Origins of Organic Compounds in Space• Research Topic 3: Rock-Water-Carbon Interactions, Organic Synthesis on Earth, and Steps to Life• Research Topic 4: Life and Habitability• Research Topic 5: Biosignatures as Facilitating Life Detection It is strongly recommended that steps be taken towards the definition and implementation of a European Astrobiology Platform (or Institute) to streamline and optimize the scientific return by using a coordinated infrastructure and funding system. Key Words: Astrobiology roadmap—Europe—Origin and evolution of life—Habitability—Life detection—Life in extreme environments. Astrobiology 16, 201–243. PMID:27003862

    This report presents the proceedings of the Klamath Basin Science Conference (February 2010). A primary purpose of the meeting was to inform and update Klamath Basin stakeholders about areas of scientific progress and accomplishment during the last 5 years. Secondary conference objectives focused on the identification of outstanding information needs and science priorities as they relate to whole watershed management, restoration ecology, and possible reintroduction of Pacific salmon associated with the Klamath Basin Restoration Agreement (KBRA). Information presented in plenary, technical, breakout, and poster sessions has been assembled into chapters that reflect the organization, major themes, and content of the conference. Chapter 1 reviews the major environmental issues and resource management and other stakeholder needs of the basin. Importantly, this assessment of information needs included the possibility of large-scale restoration projects in the future and lessons learned from a case study in South Florida. Other chapters (2-6) summarize information about key components of the Klamath Basin, support conceptual modeling of the aquatic ecosystem (Chapter 7), and synthesize our impressions of the most pressing science priorities for management and restoration. A wealth of information was presented at the conference and this has been captured in chapters addressing environmental setting and human development of the basin, hydrology, watershed processes, fishery resources, and potential effects from climate change. The final chapter (8) culminates in a discussion of many specific research priorities that relate to and bookend the broader management needs and restoration goals identified in Chapter 1. In many instances, the conferees emphasized long-term and process-oriented approaches to watershed science in the basin as planning moves forward.

    The Fifth International Conference on Inertial Fusion Sciences and Applications (IFSA 2007) was held on 9-14 September 2007 at Kobe International Conference Center in Kobe, Japan. The host organizations for this conference were Osaka University and the Institute of Laser Engineering (ILE) at Osaka University; and co-organized by the Institute Lasers and Plasmas (ILP) in France, the Commissariatá l'Energie Atomique (CEA), Lawrence Livermore National Laboratory (LLNL), National Institute for Fusion Science (NIFS) in Japan, and Kansai Photon Science Institute (KPSI), Japan Atomic Energy Agency (JAEA). The conference objective was to review the state of the art of research in inertial fusion sciences and applications since the last conference held in Biarritz, France, in 2005. 470 abstracts were accepted, and 448 persons from 18 countries attended the conference. These Proceedings contain 287 of the papers presented at IFSA 2007. This collection of papers represents the manuscripts submitted to and passing the peer review process. The program was organized with some specific features: The reviews of influential programs appeared both at the very beginning and at the very end of the Conference to attract attendance throughout the Conference. Each poster session had the same time period as a single oral session, thereby avoiding overlap with oral talks. The everyday program was structured to be as similar as possible so the attendees could easily recognize the program. With a goal of achieving inertial fusion ignition and burn propagation in the laboratory, researchers presented the exciting advances in both traditional hot spot ignition and fast ignition approach, including status report of USA's National Ignition Facility (NIF), French Laser Magajoule (LMJ), Japanese Fast Ignition Realization Experiment (FIREX), and European High Power laser Energy Research (HiPER). A particular emphasis of the meeting was that the `physics of inertial fusion' category was dominated

  11. Astrobiological Significance of Microbial Extremophiles

    2007-01-01

    The microflora of the cryosphere of planet Earth provides the best analogs for life forms that might be found in the permafrost or polar ice caps of Mars, near the surface of the cometary nuclei, or in the liquid water beneath and the ice crusts of icy moons of Jupiter and Saturn. The importance of study alkaliphilic microorganisms for astrobiology was enhanced by the findings of abundant carbonates and carbonate globules rimmed with possibly biogenic magnetites in association with the putative microfossils in the ALH84001 meteorite. Although the ALH84001 "nanofossils" were to small and simple to be unambiguously recognized as biogenic, they stimulated Astrobiology research and studies of microbial extremophiles and biomarkers in ancient rocks and meteorites. Recent studies of CI and CM carbonaceous meteorites have resulted in the detection of the well-preserved mineralized remains of coccoidal and filamentous microorganisms in cyanobacterial mats. Energy Dispersive X-ray Analysis has shown anomalous biogenic element ratios clearly indicating they are not recent biological contaminants. This paper reviews microbial extremophiles in context of their significance to Astrobiology. The study of halophilic microorganisms was started from work with saline soils and lakes, and one of the record of good growth for Haloferax mediterranei was shown at 30 percent NaC1. Although alkali-tolerant nitrifying bacteria had previously been reported, the first described alkaliphilic microorganism was the bacterium Streptococcus faecalis. Halophilic and alkaliphilic forms are relevant to conditions that might be found in closed impact basins and craters on Mars filled with evaporite deposits. The first obligately acidophilic bacterium described was Acidithiobacillus ferrooxydans (formally Thiobacillus ferrooxidans). Later thermophilic lithotrophic acidophiles were found, and the hyperacidophilic moderately thermophilic species of the genus Picrophilus were found to grow at negative p

    As more complex organic molecules are detected in the interstellar medium, the importance of heterocyclic molecules to astrobiology and the origin of life has become evident. 2-Aminothiazole and 2-aminooxazole have recently been suggested as important nucleotide precursors, highlighting azoles as potential prebiotic molecules. This study explores the gas-phase chemistry of three deprotonated azoles: oxazole, thiazole, and isothiazole. For the first time, their gas-phase acidities are experimentally determined with bracketing and H/D exchange techniques, and their reactivity is characterized with several detected interstellar neutral molecules (N{sub 2}O, O{sub 2}, CO, OCS, CO{sub 2}, and SO{sub 2}) and other reactive species (CS{sub 2}, CH{sub 3}Cl, (CH{sub 3}){sub 3}CCl, and (CH{sub 3}){sub 3}CBr). Rate constants and branching fractions for these reactions are experimentally measured using a modified commercial ion trap mass spectrometer whose kinetic data are in good accord with those of a flowing afterglow apparatus reported here. Last, we have examined the fragmentation patterns of these deprotonated azoles to elucidate their destruction mechanisms in high-energy environments. All experimental data are supported and complemented by electronic structure calculations at the B3LYP/6-311++G(d,p) and MP2(full)/aug-cc-pVDZ levels of theory.

    The O/OREOS (Organism/Organic Exposure to Orbital Stresses) nanosatellite is the first science demonstration spacecraft and flight mission of the NASA Astrobiology Small- Payloads Program (ASP). O/OREOS was launched successfully on November 19, 2010, to a high-inclination (72 deg), 650-km Earth orbit aboard a US Air Force Minotaur IV rocket from Kodiak, Alaska. O/OREOS consists of 3 conjoined cubesat (each 1000 cu cm) modules: (i) a control bus; (ii) the Space Environment Survivability of Living Organisms (SESLO) experiment; and (iii) the Space Environment Viability of Organics (SEVO) experiment. Among the innovative aspects of the O/OREOS mission are a real-time analysis of the photostability of organics and biomarkers and the collection of data on the survival and metabolic activity for microorganisms at 3 times during the 6-month mission. We report on the spacecraft characteristics, payload capabilities, and present operational phase and flight data from the O/OREOS mission. The science and technology rationale of O/OREOS supports NASA0s scientific exploration program by investigating the local space environment as well as space biology relevant to Moon and Mars missions. It also serves as a precursor for experiments on small satellites, the International Space Station (ISS), future free-flyers and lunar surface exposure facilities.

The conference was attended by more than 130 participants, and hosted about 290 oral, poster and virtual papers by more than 460 pre-registered authors. The first IC-MSQUARE consisted of different and diverging workshops and thus covered various research fields in which mathematical modelling is used, such as theoretical/mathematical physics, neutrino physics, non-integrable systems, dynamical systems, computational nanoscience, biological physics, computational biomechanics, complex networks, stochastic modelling, fractional statistics, DNA dynamics, and macroeconomics. The scientific program was rather heavy since after the Keynote and Invited Talks in the morning, two parallel sessions ran every day. However, according to all attendees, the program was excellent with a high level of talks and the scientific environment was fruitful; thus all attendees had a creative time. The mounting question is whether this occurred accidentally, or whether IC-MSQUARE is a necessity in the field of physical and mathematical modelling. For all of us working in the field, the existing and established conferences in this particular field suffer from two distinguished and recognized drawbacks: the first is the increasing orientation, while the second refers to the extreme specialization of the meetings. Therefore, a conference which aims to promote the knowledge and development of high-quality research in mathematical fields concerned with applications of other scientific fields as well as modern technological trends in physics, chemistry, biology, medicine, economics, sociology, environmental sciences etc., appears to be a necessity. This is the key role that IC-MSQUARE will play. We would like to thank the Keynote Speaker and the Invited Speakers for their significant contributions to IC-MSQUARE. We would also

    There is a long history of the microbe-collection experiments at high altitude (1). Microbes have been collected using balloons, aircraft and meteorological rockets. Spore forming fungi and Bacilli, and Micrococci have been isolated in these experiments (1). It is not clear how high do microbes go up. If the microbes might have been present even at higher altitudes, the fact would endorse the possibility of interplanetary migration of life. Tanpopo, dandelion, is the name of a grass whose seeds with floss are spread by the wind. We propose the analyses of interplanetary migration of microbes, organic compounds and meteoroids on Japan Experimental Module (JEM) of the International Space Station (ISS) (2). Ultra low-density aerogel will be used to capture micrometeoroid and debris. Particles captured by aerogel will be used for several analyses after the initial inspection of the gel and tracks. Careful analysis of the tracks in the aerogel will provide the size and velocity dependence of debris flux. The particles will be analyzed for mineralogical, organic and microbiological characteristics. Aerogels are ready for production in Japan. Aerogels and trays are space proven. All the analytical techniques are ready. In this presentation, we will present the recent results related to the microbiological analyses. The results suggested that the bleaching speeds and the spectra of fluorescence are different between different origins of the fluorescence: whether it is emitted from microbe or not. It is also shown that PCR analysis of the microbe can be used to determine the species.

    In June, The Center for Research on Parallel Computation (CRPC), an NSF-funded Science and Technology Center, hosted the 4th Annual Conference for African-American Reserachers in the Mathematical Sciences (CAARMS4) at Rice University. The main goal of this conference was to highlight current work by African-American researchers and graduate students in mathematics. This conference strengthened the mathematical sciences by encouraging the increased participation of African-American and underrepresented groups into the field, facilitating working relationships between them and helping to cultivate their careers. In addition to the talks there was a graduate student poster session and tutorials on topics in mathematics and computer science. These talks, presentations, and discussions brought a broader perspective to the critical issues involving minority participation in mathematics.

    This effort supports the Astrobiology Objective 8 the Search for LIFE ON MARS PAST AND PRESENT -(Astrobiology Program Office, 1998, p.7). The essential trade analysis is between returning very small samples to the Earth while protecting them versus in situ analysis on Mars. Developing these explicit parameters encompasses design, instrumentation, system integration, human factors and surface operations for both alternatives. This allocation of capability approach incorporates a "humans and machines in the loop" model that recognizes that every exploration system involves both humans and automated systems. The question is where in the loop they occur whether on Earth, in the Mars Base, in the rover or creeping over the Mars surface.

    New developments in the treatment and management of phenylketonuria (PKU) as well as advances in molecular testing have emerged since the National Institutes of Health 2000 PKU Consensus Statement was released. An NIH State-of-the-Science Conference was convened in 2012 to address new findings, particularly the use of the medication sapropterin to treat some individuals with PKU, and to develop a research agenda. Prior to the 2012 conference, five working groups of experts and public members met over a 1-year period. The working groups addressed the following: long-term outcomes and management across the lifespan; PKU and pregnancy; diet control and management; pharmacologic interventions; and molecular testing, new technologies, and epidemiologic considerations. In a parallel and independent activity, an Evidence-based Practice Center supported by the Agency for Healthcare Research and Quality conducted a systematic review of adjuvant treatments for PKU; its conclusions were presented at the conference. The conference included the findings of the working groups, panel discussions from industry and international perspectives, and presentations on topics such as emerging treatments for PKU, transitioning to adult care, and the U.S. Food and Drug Administration regulatory perspective. Over 85 experts participated in the conference through information gathering and/or as presenters during the conference, and they reached several important conclusions. The most serious neurological impairments in PKU are preventable with current dietary treatment approaches. However, a variety of more subtle physical, cognitive, and behavioral consequences of even well-controlled PKU are now recognized. The best outcomes in maternal PKU occur when blood phenylalanine (Phe) concentrations are maintained between 120 and 360 μmol/L before and during pregnancy. The dietary management treatment goal for individuals with PKU is a blood Phe concentration between 120 and 360 μmol/L. The use

    2012-07-01

    The discovery of a first exoplanet, in 1995, did not revolutionize but knocked astronomical sciences over. At the same time, by opening new prospects of research, in particular in the search of planets similar to the Earth and in a possible extraterrestrial life, this discovery, since then abundantly repeated, gave a new breath to the public interest for this scientific field. But is humanity ready to learn the existence from extraterrestrial forms of life or to remain, in spite of its efforts, in ignorance? The question of the plurality of the worlds is one of the oldest interrogations conveyed by the human cultures, as testified by the multiple answers which were brought to it. In the same way, the concept of life is itself an inexhaustible source of philosophical and religious reflexions, with many consequences in moral domains. It is today necessary to accompany the scientific development in the field of astrobiology by attaching the greatest importance to this intellectual patrimony. It constitutes even one of the first stages of an ethical responsibility in astrobiology, as important as that concerning planetary protection.

  13. The AstroBiology Explorer (ABE) Mission Concept

    2004-01-01

    Infrared spectroscopy in the 2.5-16 micron range is a principle means by which organic compounds can be detected and identified in space via their vibrational transitions. Ground-based, airborne, and spaceborne IR spectral studies have already demonstrated that a significant fraction of the carbon in the interstellar medium (ISM) resides in the form of complex organic molecular species. Unfortunately, neither the distribution of these materials nor their genetic and evolutionary relationships with each other or their environments are well understood. The Astrobiology Explorer (ABE) is a MIDEX mission concept currently under study by a team of partners: NASA's Ames Research Center, Ball Aerospace and Technologies Corporation, and the Jet Propulsion Laboratory. ABE will conduct IR spectroscopic observations to address outstanding important problems in astrobiology, astrochemistry, and astrophysics. The core observational program would make fundamental scientific progress in understanding (1) The evolution of ices and organic matter in dense molecular clouds and young forming stellar systems, (2) The chemical evolution of organic molecules in the ISM as they transition from AGB outflows to planetary nebulae to the general diffuse ISM to HII regions and dense clouds, (3) The distribution of organics in the diffuse ISM, (4) The nature of organics in the Solar System (in comets, asteroids, satellites), and (5) The nature and distribution of organics in local galaxies. The technical considerations of achieving these science objectives in a MIDEX-sized mission will be presented.

    The European AstRoMap project (supported by the European Commission Seventh Framework Programme) surveyed the state of the art of astrobiology in Europe and beyond and produced the first European roadmap for astrobiology research. In the context of this roadmap, astrobiology is understood as the study of the origin, evolution, and distribution of life in the context of cosmic evolution; this includes habitability in the Solar System and beyond. The AstRoMap Roadmap identifies five research topics, specifies several key scientific objectives for each topic, and suggests ways to achieve all the objectives. The five AstRoMap Research Topics are • Research Topic 1: Origin and Evolution of Planetary Systems • Research Topic 2: Origins of Organic Compounds in Space • Research Topic 3: Rock-Water-Carbon Interactions, Organic Synthesis on Earth, and Steps to Life • Research Topic 4: Life and Habitability • Research Topic 5: Biosignatures as Facilitating Life Detection It is strongly recommended that steps be taken towards the definition and implementation of a European Astrobiology Platform (or Institute) to streamline and optimize the scientific return by using a coordinated infrastructure and funding system.

  16. Understanding the nineteenth century origins of disciplines: lessons for astrobiology today?

    NASA Astrophysics Data System (ADS)

    Brazelton, William J.; Sullivan, Woodruff T., III

    2009-10-01

    Astrobiology's goal of promoting interdisciplinary research is an attempt to reverse a trend that began two centuries ago with the formation of the first specialized scientific disciplines. We have examined this era of discipline formation in order to make a comparison with the situation today in astrobiology. Will astrobiology remain interdisciplinary or is it becoming yet another specialty? As a case study, we have investigated effects on the scientific literature when a specialized community is formed by analyzing the citations within papers published during 1802-1856 in Philosophical Transactions of the Royal Society (Phil. Trans.), the most important ‘generalist’ journal of its day, and Transactions of the Geological Society of London (Trans. Geol. Soc.), the first important disciplinary journal in the sciences. We find that these two journals rarely cited each other, and papers published in Trans. Geol. Soc. cited fewer interdisciplinary sources than did geology papers in Phil. Trans. After geology had become established as a successful specialized discipline, geologists returned to publishing papers in Phil. Trans., but they wrote in the new, highly specialized style developed in Trans. Geol. Soc. They had succeeded in not only creating a new scientific discipline, but also a new way of doing science with its own modes of research and communication. A similar citation analysis was applied to papers published over the period 2001-2008 in the contemporary journals Astrobiology and the International Journal of Astrobiology to test the hypothesis that astrobiologists are in the early stages of creating their own specialized community. Although still too early to reliably detect any but the largest trends, there is no evidence yet that astrobiologists are drifting into their own isolated discipline. Instead, to date they appear to remain interdisciplinary.

    Abstract Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

    The Mars Program Plan includes an integrated and coordinated set of future candidate missions and investigations that meet fundamental science objectives of NASA and the Mars Exploration Program (MEP). At the time this paper was written, these possible future missions are planned in a manner consistent with a projected budget profile for the Mars Program in the next decade (2007-2016). As with all future missions, the funding profile depends on a number of factors that include the exact cost of each mission as well as potential changes to the overall NASA budget. In the current version of the Mars Program Plan, the Astrobiology Field Laboratory (AFL) exists as a candidate project to determine whether there were (or are) habitable zones and life, and how the development of these zones may be related to the overall evolution of the planet. The AFL concept is a surface exploration mission equipped with a major in situ laboratory capable of making significant advancements toward the Mars Program's life-related scientific goals and the overarching Vision for Space Exploration. We have developed several concepts for the AFL that fit within known budget and engineering constraints projected for the 2016 and 2018 Mars mission launch opportunities. The AFL mission architecture proposed here assumes maximum heritage from the 2009 Mars Science Laboratory (MSL). Candidate payload elements for this concept were identified from a set of recommendations put forth by the Astrobiology Field Laboratory Science Steering Group (AFL SSG) in 2004, for the express purpose of identifying overall rover mass and power requirements for such a mission. The conceptual payload includes a Precision Sample Handling and Processing System that would replace and augment the functionality and capabilities provided by the Sample Acquisition Sample Processing and Handling system that is currently part of the 2009 MSL platform.

    NASA Astrophysics Data System (ADS)

    The Nuclear Science Symposium (NSS) offers an outstanding opportunity for scientists and engineers interested or actively working in the fields of nuclear science, radiation instrumentation, software and their applications, to meet and discuss with colleagues from around the world. The program emphasizes the latest developments in technology and instrumentation and their implementation in experiments for space sciences, accelerators, other radiation environments, and homeland security. The Medical Imaging Conference (MIC) is the foremost international scientific meeting on the physics, engineering and mathematical aspects of nuclear medicine based imaging. As the field develops, multi-modality approaches are becoming more and more important. The content of the MIC reflects this, with a growing emphasis on the methodologies of X-ray, optical and MR imaging as they relate to nuclear imaging techniques. In addition, specialized topics will be addressed in the Short Courses and Workshops programs. The Workshop on Room-Temperature Semiconductor Detectors (RTSD) represents the largest forum of scientists and engineers developing new semiconductor radiation detectors and imaging arrays. Room-temperature solid-state radiation detectors for X-ray, gamma-ray, and neutron radiation are finding increasing applications in such diverse fields as medicine, homeland security, astrophysics and environmental remediation. The objective of this workshop is to provide a forum for discussion of the state of the art of material development for semiconductor, scintillator, and organic materials for detection, materials characterization, device fabrication and technology, electronics and applications.

    The discovery of traces of life in the ancient Mars meteorite triggered the development of the rapidly emerging field of Astrobiology. Astrobiologists are seeking to develop conclusive methods to recognize biosignatures and microfossils of bacteria and other microbiota as well as to understand the spatial, temporal, environmental and chemical limitations of microbial extremophiles. Recent discoveries have revealed the great distribution and diversity of microbial extremophiles on Earth and profoundly increased the probability that life may exist elsewhere in the Cosmos. The rapidly emerging science of Bacterial Paleontology has provided important new information critical to the recognition of fossil bacteria on Earth and in Astromaterials. We have recently conducted independent scanning electron microscopy and x-ray analysis investigations in the US and Russia in order to better understand the morphology and chemical composition of microfossils in ancient terrestrial rocks and carbonaceous meteorites. In this paper, we review some aspects of microbial extremophiles of Earth as modals for life on other bodies of the Solar System. We consider several of the important chemical, mineral and morphological biomarkers that provide definitive evidence of biogenic activity in ancient rocks and meteorites. We present Environmental Scanning Electron Microscope images of microfossils found in-situ in freshly fractured meteorite surfaces and describe Energy Dispersive Spectroscopy and Link microprobe analysis of the chemical elements in the mineralized and/or kerogenous microfossils and meteorite rock matrix. We also discuss technqiues and methods that may be used to help discriminate indigenous microfosils from recent terrestrial contaminants. We will also present new data from our in-situ investigations of living cyanobacteria and bacteria and freshly broken surfaces of terrestrial rocks and meteorites. Comparative analysis of these images are interpreted as providing

  5. Role of the observer in the scientific process in astrobiology and in defining life

    NASA Astrophysics Data System (ADS)

    Kolb, Vera M.

    2010-09-01

    The role of the observer in the scientific process has been studied in various contexts, including philosophical. It is notorious that the experiments are theory-loaded, that the observers pick and choose what they consider important based on their scientific and cultural backgrounds, and that the same phenomenon may be studied by different observers from different angles. In this paper we critically review various authors' views of the role of the observer in the scientific process, as they apply to astrobiology. Astrobiology is especially vulnerable to the role of the observer, since it is an interdisciplinary science. Thus, the backgrounds of the observers in the astrobiology field are even more heterogeneous than in the other sciences. The definition of life is also heavily influenced by the observer of life who injects his/her own prejudices in the process of observing and defining life. Such prejudices are often dictated by the state of science, instrumentation, and the science politics at the time, as well as the educational, scientific, cultural and other background of the observer.

    2006-01-01

    The AstroBiology Explorer (ABE) and the Astrobiology Space InfraRed Explorer (ASPIRE) Mission Concepts are two missions designed to address the questions (1) Where do we come from? and (2) Are we alone? as outlined in NASA s Origins Program using infrared spectroscopy to explore the identity, abundance, and distribution of molecules of astrobiological importance throughout the Universe. The ABE mission s observational program is focused on six tasks to: (1) Investigate the evolution of ice and organics in dense clouds and star formation regions, and the young stellar/planetary systems that form in them; (2) Measure the evolution of complex organic molecules in stellar outflows; (3) Study the organic composition of a wide variety of solar system objects including asteroids, comets, and the planets and their satellites; (4) Identify organic compounds in the diffuse interstellar medium and determine their distribution , abundance, and change with environment; (5) Detect and identify organic compounds in other galaxies and determine their dependence on galactic type; and (6) Measure deuterium enrichments in interstellar organics and use them as tracers of chemical processes. The ASPIRE mission s observational program expands upon ABE's core mission and adds tasks that (7) Address the role of silicates in interstellar organic chemistry; and (8) Use different resolution spectra to assess the relative roles and abundances of gas- and solid-state materials. ABE (ASPIRE) achieves these goals using a highly sensitive, cryogenically-cooled telescope in an Earth drift-away heliocentric orbit, armed with a suite of infrared spectrometers that cover the 2.5-20(40) micron spectral region at moderate spectral resolution (R>2000). ASPIRE's spectrometer complement also includes a high-resolution (R>25,000) module over the 4-8 micron spectral region. Both missions target lists are chosen to observe a statistically significant sample of a large number of objects of varied types in

    Members of the Colorado Center for Lunar Dust and Atmospheric Studies (CCLDAS) initiated the Lunar Graduate Conference (LunGradCon), modeled after the highly successful Astrobiology Graduate Conference (AbGradCon). The purpose of this conference is to enhance the professional development of graduate students and early postdoctoral researchers by providing an opportunity to present and discuss scientific research in an environment of their peers. For the first two years, LunGradCon has been held as a one-day conference in conjunction with the NASA Lunar Science Institue's (NLSI) Lunar Science Forum at the NASA Ames Research Center. Activities include an invited overview talk on each of the NASA Lunar Science Institute's three main research areas (OF the Moon, ON the Moon, and FROM the Moon), submitted oral presentations from graduate students and postdoctoral researchers, and networking opportunities with established member of the lunar science community and the NLSI. In each of the first two years of LunGradCon, there have been 20-25 attendees, with about 15 of those presenting submitted talks. Each speaker received feedback forms from the other participants in order to improve on their presentation techniques. Participants also provided feedback on the conference as a whole in order to evaluate the content and provide suggestions for improvement in following years. Overall, the feedback has been extremely positive. This talk will summarize the achievements of past LunGradCons and plans for expansion of the conference to ensure a long-term positive impact on the early careers of future lunar, planetary and space science researchers.

  11. Cosmic evolution: the context for astrobiology and its cultural implications

    Dick, Steven J.

    2012-10-01

    Astrobiology must be seen in the context of cosmic evolution, the 13.7 billion-year master narrative of the universe. The idea of an evolving universe dates back only to the 19th century, and became a guiding principle for astronomical research only in the second half of the 20th century. The modern synthesis in evolutionary biology hastened the acceptance of the idea in its cosmic setting, as did the confirmation of the Big Bang theory for the origin of the universe. NASA programmes such as Origins incorporated it as a guiding principle. Cosmic evolution encompasses physical, biological and cultural evolution, and may result in a physical, biological or postbiological universe, each with its own implications for long-term human destiny, and each imbuing the meaning of life with different values. It has the status of an increasingly accepted worldview that is beginning to have a profound effect not only in science but also in religion and philosophy.

    The search for evidence of life beyond Earth illustrates how the charters of NASA and the National Park Service share common ground. The mission of NPS is to preserve unimpaired the natural and cultural resources of the National Park System for the enjoyment, education and inspiration of this and future generations. NASA's Astrobiology program seeks to understand the origins, evolution and distribution of life in the universe, and it abides by the principles of planetary stewardship, public outreach, and education. We cannot subject planetary exploration destinations to Earthly biological contamination both for ethical reasons and to preserve their scientific value for astrobiology. We respond to the public's interest in the mysteries of life and the cosmos by honoring their desire to participate in the process of discovery. We involve youth in order to motivate career choices in science and technology and to perpetuate space exploration. The search for evidence of past life on Mars illustrates how the missions of NASA and NPS can become synergistic. Volcanic activity occurs on all rocky planets in our Solar System and beyond, and it frequently interacts with water to create hydrothermal systems. On Earth these systems are oases for microbial life. The Mars Exploration Rover Spirit has found evidence of extinct hydrothermal system in Gusev crater, Mars. Lassen Volcanic National Park provides a pristine laboratory for investigating how microorganisms can both thrive and leave evidence of their former presence in hydrothermal systems. NASA scientists, NPS interpretation personnel and teachers can collaborate on field-oriented programs that enhance Mars mission planning, engage students and the public in science and technology, and emphasize the ethics of responsible exploration.

    The 2011 Gordon Research Conference on X-ray Science will feature forefront x-ray-based science enabled by the rapid improvements in synchrotron and x-ray laser sources. Across the world, x-ray sources are playing an increasingly important role in physics, materials, chemistry, and biology, expanding into ever broadening areas of science and engineering. With the first hard x-ray free electron laser source beginning operation and with other advanced x-ray sources operational and planned, it is a very exciting and pivotal time for exchange ideas about the future of x-ray science and applications. The Conference will provide the forum for this interaction. An international cast of speakers will illuminate sessions on ultrafast science, coherence, imaging, in situ studies, extreme conditions, new developments in optics, sources, and detectors, inelastic scattering, nanoscience, life science, and energy sciences. The Conference will bring together investigators at the forefront of these areas, and will provide a venue for young scientists entering a career in x-ray research to present their research in poster format, hold discussions in a friendly setting, and exchange ideas with leaders in the field. Some poster presenters will be selected for short talks. The collegial atmosphere of this Conference, with ample time for discussion as well as opportunities for informal gatherings in the afternoons and evenings, will provide an avenue for scientists from different disciplines to exchange ideas about forefront x-ray techniques and will promote cross-fertilization between the various research areas represented.

    Two phases of Penetrator development activities have been funded by ESA. The first phase focussed on the mission and system definition of a penetrator and delivery system for a mission to Europa and the second phase provided an update of the penetrator design for a larger suite of instruments focused on astrobiology and the demonstration of key system technologies through a programme of small scale and full scale testing. The science focus for the Europa penetrator is Astrobiology while the key science goals can be achieved within the first day of operation but a longer lifetime is required for the transmission of the science data to the orbiter. The extreme temperature environment of the Europan surface drove the design to a solution of a Penetrator with two separate bays. The front bay will be a short lifetime bay which will sample the surface and complete all analysis and data transfer within 10 hours. The rear bay is a warm bay which will house EPSC Abstracts Vol. 9, EPSC2014-642, 2014 European Planetary Science Congress 2014 c Author(s) 2014 EPSC European Planetary Science Congress the penetrator support systems required to transmit all collected data to the orbiter. The scientific instruments housed by the penetrator includeds a optical microimager, a habitability package and a mass spectrometer. A drilling and sampling mechanism is used for accessing the icy material outside the Penetrator for analysis. Small scale trails have been undertaken at the University of Cambridge Cavendish Laboratory to validate the impact modelling techniques and the robustness of critical components. A range of trials have been carried out to assess survivability of key elements of the design, including the sampling mechanism, potting compounds, accelerometers, shell, batteries and Torlon suspension springs. Full scale trials have been carried out to test the overall structural integrity of the system and the penetration profile. This programme was carried out in June 2013 at the

    Ground based experiments, conducted in the controlled planetary and space environment simulation facilities PSI at DLR, are used to investigate astrobiological questions and to complement the corresponding experiments in LEO, for example on free flying satellites or on space exposure platforms on the ISS. In-orbit exposure facilities can only accommodate a limited number of experiments for exposure to space parameters like high vacuum, intense radiation of galactic and solar origin and microgravity, sometimes also technically adapted to simulate extraterrestrial planetary conditions like those on Mars. Ground based experiments in carefully equipped and monitored simulation facilities allow the investigation of the effects of simulated single environmental parameters and selected combinations on a much wider variety of samples. In PSI at DLR, international science consortia performed astrobiological investigations and space experiment preparations, exposing organic compounds and a wide range of microorganisms, reaching from bacterial spores to complex microbial communities, lichens and even animals like tardigrades to simulated planetary or space environment parameters in pursuit of exobiological questions on the resistance to extreme environments and the origin and distribution of life. The Planetary and Space Simulation Facilities PSI of the Institute of Aerospace Medicine at DLR in Köln, Germany, providing high vacuum of controlled residual composition, ionizing radiation of a X-ray tube, polychromatic UV radiation in the range of 170-400 nm, VIS and IR or individual monochromatic UV wavelengths, and temperature regulation from -20°C to +80°C at the sample size individually or in selected combinations in 9 modular facilities of varying sizes are presented with selected experiments performed within.

    2006-01-01

    Astrobiology flight experiments require highly sensitive instrumentation for in situ analysis of volatile chemical species and minerals present in the atmospheres and surfaces of planets, moons, and asteroids. The complex mixtures encountered place a heavy burden on the analytical instrumentation to detect and identify all species present. The use of land rovers and balloon aero-rovers place additional emphasis on miniaturization of the analytical instrumentation. In addition, smaller instruments, using tiny amounts of consumables, allow the use of more instrumentation and/or longer mission life for stationary landers/laboratories. We describe here the development of a miniature GC - Minicell Ion Mobility Spectrometer (IMS) under development through NASA's Astrobiology Science and Technology Instrument Development (ASTID) Program and NASA's Small Business Innovative Research (SBIR) Program.

    2010-12-01

    The Georgia Tech Center for Ribosomal Origins and Evolution, a center funded by the NASA Astrobiology Institute, developed an educational summer program titled, “Life on the Edge: Astrobiology.” The purpose of the program was to expose high school educators to the field of astrobiology and provide them with skills and classroom activities necessary to foster student interest in scientific discovery on Earth and throughout the universe. Astrobiology activities for a week-long summer enrichment program for high school students was developed by three high school educators, two undergraduate students and faculty in the Schools of Biology, and Chemistry and Biochemistry at Georgia Tech. Twenty-four high school students were introduced to hands-on activities and techniques such as gel electrophoresis, thin layer chromatography, and manual polymerase chain reaction. The impact of the astrobiology summer program on teachers and high school students will be discussed.

  13. Ethical issues in astrobiology: a Christian perspective (Invited)

    NASA Astrophysics Data System (ADS)

    Randolph, R. O.

    2009-12-01

    With its focus on the origin, extent, and future of life, Astrobiology raises exciting, multidisciplinary questions for science. At the same time, Astrobiology raises important questions for the humanities. For instance, the prospect of discovering extraterrestrial life - either intelligent or unintelligent - raises questions about humans’ place in the universe and our relationship with nature on planet Earth. Fundamentally, such questions are rooted in our understanding of what it means to be human. From a Christian perspective, the foundational claim about human nature is that all persons bear the "imago dei", the image of God. This concept forms the basis for how humans relate to one another (dignity) and how humans relate to nature (stewardship). For many Christians the "imago dei" also suggests that humans are at the center of the universe. The discovery of extraterrestrial life would be another scientific development - similar to evolution - that essentially de-centers humanity. For some Christian perspectives this de-centering may be problematic, but I will argue that the discovery of extraterrestrial life would actually offer a much needed theological corrective for contemporary Christians’ understanding of the "imago dei". I will make this argument by examining two clusters of ethical issues confronting Astrobiology: 1. What ethical obligations would human explorers owe to extraterrestrial life? Are there ethical obligations to protect extraterrestrial ecosystems from harm or exploitation by human explorers? Do our ethical considerations change, if the extraterrestrial life is a “second genesis;” in other words a form of life completely different and independent from the carbon-based life that we know on Earth? 2. Do we have an ethical obligation to promote life as much as we can? If human explorers discover extraterrestrial life and through examination determine that it is struggling to survive, do we have an ethical obligation to assist that

  16. Future Exploration of Titan -Astrobiological Aspects

    NASA Astrophysics Data System (ADS)

    Lorenz, Ralph

    The only known chemical systems sophisticated enough to execute the functions of life are those made from carbon-based compounds. Saturn's moon Titan presents us with an extensive and rich inventory of complex organics, and is therefore of great astrobiological interest. Astrobiology at Titan has two principal facets. First is the prospect of an internal water ocean (like other icy satellites, albeit perhaps with a higher concentration of ammonia and organics) and related aqueous chemistry that may occur in transient surface exposures of water in impact melt sheets or cryovolcanic flows. The other is chemistry that may occur in the nonpolar solvents ethane and methane that form Titan's polar lakes and seas. The astrobiological potential of the latter systems is essentially unknown, although the environments are more accessible to affordable exploration. Recent studies have identified many mission possibilities within the framework of a Flagship-class mission, including orbiters, landers on (organic) dunefields, landers in lakes, and aerial platforms such as Montgolfiere balloons acting in a coordinated, synergistic manner. However, such a mission is not likely to take place until circa 2030. More modest missions, that might consider one of these elements on a standalone basis, could be considered under PI-led mission categories such as New Frontiers or Discovery. A lake lander, for example, could carry a mass spectrometer to analyze the detailed composition of a lake. Even the earliest of these possibilities, the Titan Mare Explorer (TiME) Discovery proposal presently being considered, would not arrive until 2022-2023. In the meantime, the recent approval by NASA of the Cassini Solstice Mission (until 2017) will enable many new findings at Titan, in particular with regard to Titan's interior, and seasonal changes in its organic lakes.

  18. From systems chemistry to systems astrobiology: life in the universe as an emergent phenomenon

    Although astrobiology is a science midway between the life and physical sciences, it has surprisingly remained largely disconnected from recent trends in certain branches of both life and physical sciences. We discuss potential applications to astrobiology of approaches that aim at integrating rather than reducing. Aiming at discovering how systems properties emerge has proved valuable in chemistry and in biology. The systems approach should also yield insights into astrobiology, especially concerning the ongoing search for alternative abodes for life. This is feasible since new data banks in the case of astrobiology - considered as a branch of biology - are of a geophysical/astronomical kind, rather than the molecular biology data that are used for questions related firstly, to genetics in a systems context and secondly, to biochemistry for solving fundamental problems, such as protein or proteome folding. By focusing on how systems properties emerge in astrobiology we consider the question: can life in the universe be interpreted as an emergent phenomenon? In the search for potential habitable worlds in our galactic sector with current space missions, extensive data banks of geophysical parameters of exoplanets are rapidly emerging. We suggest that it is timely to consider life in the universe as an emergent phenomenon that can be approached with methods beyond the science of chemical evolution - the backbone of previous research in questions related to the origin of life. The application of systems biology to incorporate the emergence of life in the universe is illustrated with a diagram for the familiar case of our own planetary system, where three Earth-like planets are within the habitable zone (HZ) of a G2 V (the complete terminology for the Sun in the Morgan-Keenan system) star. We underline the advantage of plotting the age of Earth-like planets against large atmospheric fraction of a biogenic gas, whenever such anomalous atmospheres are discovered in

    The Mars Atmospheric Chemistry and Astrobiology (MACA) Workshop was held on the California Institute of Technology campus December 17-18, 2001. The prime objective of the workshop was to consider whether extant life beneath the surface, if it exists, would be in contact with the atmosphere and introduce a detectable signature in the atmosphere. To answer this question, the workshop also explored how well we understood the abiotic chemistry of the current atmosphere and other drivers of atmospheric composition (volcanoes, surface-atmosphere interactions, escape). The conclusions from this workshop will be presented.

    The 3rd International Conference on Science & Engineering in Mathematics, Chemistry and Physics 2015 (ScieTech 2015), was held at The Westin Resort Nusa Dua, Bali on 31 January - 1 February 2015. The ScieTech 2015 conference is aimed to bring together researchers, engineers and scientists from around the world. ScieTech 2015 is placed on promoting interaction between the theoretical, experimental, and applied communities, so that a high level exchange is achieved in new and emerging areas within mathematics, chemistry and physics. As we already know that science and technology have brought tremendous benefits for human civilization. People are becoming healthier, wealthier, better educated, more peaceful, increasingly connected, and living longer. Of course, science and technology provide many answers to global challenges, but we will face more complex problems in the next decade due to increasing world population, limitation of energy, and climate change. Therefore, researchers should be more active in conducting research that enables collaboration between one and the others. Interdisciplinary cooperation is absolutely necessary in order to create a smart system for solving the global problems. We need a global and general long-term view of the future with long-range goals for solving complex problems in next decade. Therefore the conference was held to be a forum for researchers from different disciplines to start collaborating and conducting research that provides a solution to the global issues. The theme of ScieTech 2015 was ''The interdisciplinary Application between Mathematics, Chemistry and Physics to enhance the Quality of Life''. We would like to express our sincere gratitude to all in the Technical Program Committee who have reviewed the papers and developed a very interesting conference program as well as the invited and plenary speakers. This year, we received 197 papers and after rigorous review, 59 papers were accepted. The participants came from 19

    In this paper we describe a potential new Explorer-class space mission, the AstroBiology Explorer (ABE), consisting of a relatively modest dedicated space observatory having a 50 cm aperture primary mirror which is passively cooled to T less than 65 K, resides in a low-background orbit (heliocentric orbit at 1 AU, Earth drift-away), and is equipped with a suite of three moderate order (m approx. 10) dispersive spectrographs equipped with first-order cross-dispersers in an "echellette" configuration and large format (1024xl024 pixel) near- and mid-IR detector arrays cooled by a modest amount of cryogen. Such a system would be capable of addressing outstanding problems in Astrochemistry and Astrophysics that are particularly relevant to Astrobiology and addressable via astronomical observation. The observational program of this mission would make fundamental scientific progress in each of the key areas of the cosmic history of molecular carbon, the distribution and chemistry of organic compounds in the diffuse and dense interstellar media, and the evolution of ices and organic matter in young planetary systems. ABE could make fundamental progress in all of these areas by conducting an approximately one year mission to obtain a coordinated set of infrared spectroscopic observations over the 2.5-20 micrometers spectral range at spectral resolutions of R greater than or equal to 1000 of approximately 1000 galaxies, stars, planetary nebulae, and young star planetary systems.

    Introduction: Infrared spectroscopy in the 2.5- 16 micron range is a principle means by which organic compounds can be detected and identified in space via their vibrational transitions. Ground-based, airborne, and spaceborne IR spectral studies have already demonstrated that a significant fraction of the carbon in the interstellar medium (ISM) resides in the form of complex organic molecular species. Furthermore, the presence of D-enriched organics in meteorites suggests that a portion of these materials survives incorporation into protosolar nebulae. Unfortunately, neither the distribution of these materials in space nor their genetic and evolutionary relationships with each other or their environments are currently well understood. The Astrobiology Explorer (ABE) is a MIDEX mission concept designed to use infrared spectroscopy to address outstanding problems in Astrochemistry which are particularly relevant to Astrobiology and are amenable to astronomical observation. ABE is currently under study at NASA's Ames Research Center in collaboration with Ball Aerospace and Technologies Corporation and the Jet Propulsion Laboratory. ABE was selected for Phase A study during the last MIDEX AO round, but has yet to be selected for flight.

    Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

    A conference was called in the hope that by applying the knowledge science can give, family planners can improve the form and efficiency of their programs. A summary of the major points made by the participants is presented. Philip Huaser urger employing a full battery of social scientists to do basic research into the theory and methodology of surveys. Michael Young proposed shifting the focus from individual use of contraception to social policies designed to reduce birthrates. Le Bogart commented on the ignorance about the psychological relationship between sexuality and procreation. Brewster Smith suggested a psychological perspective from which to examine questions involved in family planning. Orville Brim, Jr., argued that sociological theorists must learn to work with technologists to develop contraceptive devices and other tools of family planning programs. Richard Bell reported on the physical and mental impairments in children from large families with short birth intervals. Reuben Hill focused on family studies which see man as an initiator in the social process, as opposed to the passive picture painted by demographers. A lively discussion on the use of mass communications in the spread of family planning was ushered in by Daniel Lerner. Dr. Freedman wondered if family planning communications should be designed primarily for education or persuasion, seeing greater numbers of recruits in the former. Cultural innovations from an anthropological point of view were discussed by George Foster, who suggested that people are so pragmatic that they will accept any innovation that meets a need in their lives. Everett Rogers reported on research in the diffusion of agricultural innovations. A discussion on barriers to effective organization was introduced by Nicholas Demarath. PMID:12255222

    Astrobiology flight experiments require highly sensitive instrumentation for in situ analysis of volatile chemical species and minerals present in the atmospheres and surfaces of planets, moons, and asteroids. The complex mixtures encountered place a heavy burden on the analytical instrumentation to detect and identify all species present. The use of land rovers and balloon aero-rovers place additional emphasis on miniaturization of the analytical instrumentation. In addition, smaller instruments, using tiny amounts of consumables, allow the use of more instrumentation and/or ionger mission life for stationary landers/laboratories. The miniCometary Ice and Dust Experiment (miniCIDEX), which combined Gas Chromatography (GC) with helium Ion Mobility Spectrometry (IMS), was capable of providing the wide range of analytical information required for Astrobiology missions. The IMS used here was based on the PCP model 111 IMS. A similar system, the Titan Ice and Dust Experiment (TIDE), was proposed as part of the Titan Orbiter Aerorover Mission (TOAM). Newer GC systems employing Micro Electro- Mechanical System (MEMS) based technology have greatly reduced both the size and resource requirements for space GCs. These smaller GCs, as well as the continuing miniaturization of Astrobiology analytical instruments in general, has highlighted the need for smaller, dry helium IMS systems. We describe here the development of a miniature, MEMS GC-IMS system (MEMS GC developed by Thorleaf Research Inc.), employing the MiniCell Ion Mobility Spectrometer (IMS), from Ion Applications Inc., developed through NASA's Astrobiology Science and Technology Instrument Development (ASTID) Program and NASA s Small Business Innovative Research (SBIR) Program.

    A number of serious environmental health hazards created by under-regulated/unregulated industries have morphed into public health crises around the world. The Conference on Corporate Interference with Science and Health (the Conference) was held to examine this trend in three economically significant industries: fracking, food, and wireless. The Conference provided an overview of the structures of these three industries and the history of standard-setting therein, identified the sources of environmental exposures created by these industries, and surveyed the health consequences of these exposures and the policies that have resulted in them. It then examined corporate influence on the setting of these policies and the production of scientific studies and interpretation of their results. The Conference also analyzed the general influence of corporations on the political system and the relationship of this conflict of interest to the aforementioned topics. The concluding discussion focused on what solutions could be implemented to improve public health, including what institutional changes are necessary to promote public awareness and change policy.

    We are early-career scientists jointly leading a project to write 'The Astrobiology Primer', a brief but comprehensive introduction to astrobiology, and we are using the process of producing the document as an innovative way of strengthening the international community of early-career astrobiologists. Astrobiology is the study of the origin, evolution, distribution and future of life in our universe. It includes not just study of life on Earth, but also the potential for life to exist beyond Earth, and the development of techniques to search for such life. It therefore incorporates geological and earth sciences, life sciences, chemistry, astronomy and planetary sciences. This requires astrobiologists to integrate these different disciplines in order to address questions such as 'How did Earth and its biosphere originate?', 'How do life and the physical, chemical and geological cycles on Earth interact, and affect each other?' and so 'What does life on Earth tell us about the habitability of environments outside Earth?'. The primer will provide a brief but comprehensive introduction to the field; it will be significantly more comprehensive than a normal review paper but much shorter than a textbook. This project is an initiative run entirely by early-career scientists, for the benefit of other early-career scientists and others. All the writers and editors of the primer are graduate/post-graduate students or post-doctoral fellows, and our primary target group for the primer is other early-career scientists, although we hope and expect that the primer will also be useful far more broadly in education and outreach work. An Astrobiology Primer was first published in 2006(Ref1), written and edited by a small group of early-career astrobiologists to provide an introduction to astrobiology for other early-career scientists new to the field. It has been used not only by the target group for private study, but in formal education and outreach settings at universities and

    Raman spectroscopy has proved to be a very useful technique in astrobiology research. Especially, working with mobile instrumentation during fieldwork can provide useful experiences in this field. In this work, we provide an overview of some important aspects of this research and, apart from defining different types of mobile Raman spectrometers, we highlight different reasons for this research. These include gathering experience and testing of mobile instruments, the selection of target molecules and to develop optimal data processing techniques for the identification of the spectra. We also identify the analytical techniques that it would be most appropriate to combine with Raman spectroscopy to maximize the obtained information and the synergy that exists with Raman spectroscopy research in other research areas, such as archaeometry and forensics.

    The review is dedicated to the new group of extremophiles - iron tolerant cyanobacteria. The authors have analyzed earlier published articles about the ecology of iron tolerant cyanobacteria and their diversity. It was concluded that contemporary iron depositing hot springs might be considered as relative analogs of Precambrian environment. The authors have concluded that the diversity of iron-tolerant cyanobacteria is understudied. The authors also analyzed published data about the physiological peculiarities of iron tolerant cyanobacteria. They made the conclusion that iron tolerant cyanobacteria may oxidize reduced iron through the photosystem of cyanobacteria. The involvement of both Reaction Centers 1 and 2 is also discussed. The conclusion that iron tolerant protocyanobacteria could be involved in banded iron formations generation is also proposed. The possible mechanism of the transition from an oxygenic photosynthesis to an oxygenic one is also discussed. In the final part of the review the authors consider the possible implications of iron tolerant cyanobacteria for astrobiology.

    The 11th Asia-Pacific Conference on Plasma Science and Technology (APCPST-11) was held in Kyoto, Japan on 2-5 October 2012 with the 25th Symposium on Plasma Science for Materials (SPSM-25). SPSM has been held annually since 1988 under the sponsorship of The 153rd Committee on Plasma Materials Science, Japan Society for the Promotion of Science (JSPS). This symposium is one of the major activities of the Committee, which is organized by researchers in academia and industry for the purpose of advancing intersectional scientific information exchange and discussion of science and technology of plasma materials processing. APCPST and SPSM are jointly held biennially to survey the current status of low temperature and thermal plasma physics and chemistry for industrial applications. The whole area of plasma processing was covered from fundamentals to applications. Previous meetings were held in China, Japan, Korea, and Australia, attended by scientists from the Asia-Pacific and other countries. The joint conference was organized in plenary lectures, invited, contributed oral presentations and poster sessions. At this meeting, we had 386 participants from 10 countries and 398 presentations, including 26 invited presentations. This year, we arranged special topical sessions that covered green innovation, life innovation, and technical reports from industry. This conference seeks to bring the plasma community together and to create a forum for discussing the latest developments and issues, the challenges ahead in the field of plasma research and applications among engineers and scientists in Asia, the Pacific Rim, as well as Europe. This volume presents 44 papers that were selected via a strict peer-review process from full papers submitted for the proceedings of the conference. The topics range from the basic physics and chemistry of plasma processing to a broad variety of materials processing and environmental applications. This volume offers an overview of recent

    2014-05-01

    We performed a series of field research campaigns (ILEWG EuroMoonMars) in the extreme Utah desert relevant to Mars environments, and in order to help in the interpretation of Mars missions measurements from orbit (MEX, MRO) or from the surface (MER, MSL), or Moon geochemistry (SMART-1, LRO). We shall give an update on the sample analysis in the context of habitability and astrobiology. Methods & Results: In the frame of ILEWG EuroMoonMars campaigns (2009 to 2013) we deployed at Mars Desert Research station, near Hanksville Utah, a suite of instruments and techniques [A, 1, 2, 9-11] including sample collection, context imaging from remote to local and microscale, drilling, spectrometers and life sensors. We analyzed how geological and geochemical evolution affected local parameters (mineralogy, organics content, environment variations) and the habitability and signature of organics and biota. Among the important findings are the diversity in the composition of soil samples even when collected in close proximity, the low abundances of detectable PAHs and amino acids and the presence of biota of all three domains of life with significant heterogeneity. An extraordinary variety of putative extremophiles was observed [3,4,9]. A dominant factor seems to be soil porosity and lower clay-sized particle content [6-8]. A protocol was developed for sterile sampling, contamination issues, and the diagnostics of biodiversity via PCR and DGGE analysis in soils and rocks samples [10, 11]. We compare the 2009 campaign results [1-9] to new measurements from 2010-2013 campaigns [10-12] relevant to: comparison between remote sensing and in-situ measurements; the study of minerals; the detection of organics and signs of life.

  8. XVII International AIDS Conference: From Evidence to Action - Social, behavioural and economic science and policy and political science

    2009-01-01

    AIDS 2008 firmly established stigma and discrimination as fundamental priorities in the push for universal access to HIV prevention, treatment, care and support. Conference sessions and discussions reinforced the tangible negative effects of stigma on national legislation and policies. A strong theme throughout the conference was the need to replace prevention interventions that focus exclusively on individual behaviour change or biomedical prevention interventions with "combination prevention" approaches that address both individual and structural factors that increase vulnerability to HIV infection. Several high-level sessions addressed various aspects of the debate over "vertical" (disease-specific) versus "horizontal" (health systems) funding. The majority of evidence presented at the conference suggests that HIV investments strengthen health systems through the establishment of clinical and laboratory infrastructure, strengthened supply and procurement systems, improvements in health care worker training, and increased community engagement. Human rights were a focal point at the conference; several presentations emphasized the importance of securing human rights to achieve universal access goals, including workplace discrimination, travel restrictions, gender inequality, and the criminalization of homosexuality, drug use, sex work, and HIV transmission and/or exposure.

  11. Astrobiology and green chemistry: a new pedagogical connection

    Kolb, Vera M.

    2009-08-01

    Various pedagogical approaches are needed to introduce astrobiology into the chemistry curriculum. We are developing a new approach in which we connect green chemistry with astrobiology. Green chemistry is chemistry which is environmentally friendly. One obvious way for the organic chemistry to be environmentally friendly is to use water as solvent, instead of more toxic organic solvents. Another approach is to run so-called solventless reactions. For example, as the solid materials are mixed together, the melting point of the mixture is lower than the melting points of its individual components (the principle of the mixed-melting point). In some cases the entire mixture may melt upon mixing. The reactions would then occur in a viscous semi-solid state. An additional approach is to run the reactions by utilizing enzymes or man-made protein mimics as catalysts instead of toxic catalysts, such as those based on the transition metals. These and some other known examples of green chemistry have a great potential for astrobiology. The astrobiological reactions typically occur in water (e.g. prebiotic soup), in the solid mixtures (e.g. on the meteors), and may be catalyzed by various short peptides. The connection between the green chemistry principles and astrobiology represents a new pedagogical approach for infusion of astrobiology into the organic chemistry.

    Seckbach, Joseph; Chela-Flores, Julian

    2015-09-01

    We review the various manifestations of the evolution of life in extreme environments. We review those aspects of extremophiles that are most relevant for astrobiology. We are aware that geothermal energy triggering sources of heat in oceanic environments are not unique to our planet, a fact that was exposed by the Voyager mission images of volcanic activity on Io, the Jovian moon. Such activity exceeded by far what was known form terrestrial geology. The science of astrobiology has considered the possible presence of several moon oceans in the vicinity of both giant gas and icy planets. These watery environments include, not only Europa (strongly suggested by data from the Galileo mission), but the Voyager flybys exposed, not only the unusual geothermal activity on Io, but also the possible presence of subsurface oceans and some geothermal activity on the Neptune's moon Triton. More recently, calculations of Hussmann and coworkers with available data do not exclude that even Uranus moons may be candidates for bearing subsurface oceans. These possibilities invite a challenge that we gladly welcome, of preliminary discussions of habitability of extremophiles in so far novel environments for the science of astrobiology. Nevertheless, such exploration is currently believed to be feasible with the new generations of missions suggested for the time window of 2030 - 2040, or even earlier. We are envisaging, not only the current exploration of the moons of Saturn, but in the coming years we expect to go beyond to Uranus and Neptune to include dwarf planets and trans-neptunian worlds. Consequently, it is necessary to begin questioning whether the Europa-like conditions for the evolution of microorganisms are repeatable elsewhere. At present three new missions are in the process of being formulated, including the selection of payloads that will be necessary for the exploration of the various so far unexplored moons.

  1. Astrobiological and Geological Implications of Convective Transport in Icy Outer Planet Satellites

    2005-01-01

    The oceans of large icy outer planet satellites are prime targets in the search for extraterrestrial life in our solar system. The goal of our project has been to develop models of ice convection in order to understand convection as an astrobiologically relevant transport mechanism within icy satellites, especially Europa. These models provide valuable constraints on modes of surface deformation and thus the implications of satellite surface geology for astrobiology, and for planetary protection. Over the term of this project, significant progress has been made in three areas: (1) the initiation of convection in large icy satellites, which we find probably requires tidal heating; (2) the relationship of surface features on Europa to internal ice convection, including the likely role of low-melting-temperature impurities; and (3) the effectiveness of convection as an agent of icy satellite surface-ocean material exchange, which seems most plausible if tidal heating, compositional buoyancy, and solid-state convection work in combination. Descriptions of associated publications include: 3 published papers (including contributions to 1 review chapter), 1 manuscript in revision, 1 manuscript in preparation (currently being completed under separate funding), and 1 published popular article. A myriad of conference abstracts have also been published, and only those from the past year are listed.

  9. Volcanic Rocks As Targets For Astrobiology Missions

    NASA Astrophysics Data System (ADS)

    Banerjee, N.

    2010-12-01

    Almost two decades of study highlight the importance of terrestrial subaqueous volcanic rocks as microbial habitats, particularly in glass produced by the quenching of basaltic lava upon contact with water. On Earth, microbes rapidly begin colonizing glassy surfaces along fractures and cracks exposed to water. Microbial colonization of basaltic glass leads to enhanced alteration through production of characteristic granular and/or tubular bioalteration textures. Infilling of formerly hollow alteration textures by minerals enable their preservation through geologic time. Basaltic rocks are a major component of the Martian crust and are widespread on other solar system bodies. A variety of lines of evidence strongly suggest the long-term existence of abundant liquid water on ancient Mars. Recent orbiter, lander and rover missions have found evidence for the presence of transient liquid water on Mars, perhaps persisting to the present day. Many other solar system bodies, notably Europa, Enceladus and other icy satellites, may contain (or have once hosted) subaqueous basaltic glasses. The record of terrestrial glass bioalteration has been interpreted to extend back ~3.5 billion years and is widespread in modern oceanic crust and its ancient metamorphic equivalents. The terrestrial record of glass bioalteration strongly suggests that glassy or formerly glassy basaltic rocks on extraterrestrial bodies that have interacted with liquid water are high-value targets for astrobiological exploration.

    The Astrobiology Space Infrared Explorer (ASPIRE) Mission is one of the Origins Probe Mission Concepts that is currently being studied in preparation for inputs to the upcoming Decadal Survey. The mission is a cooled 1-m class telescope optimized to efficiently obtain high quality infrared spectra in the 2.5-36 micron wavelength region. The principal goal of the mission is to detect, identify, and determine the abundance of molecular species, particularly organics, throughout the universe. This will be done by obtaining spectra for a comprehensive range of Solar System, galactic, and extra-galactic environments and the interfaces between them. ASPIRE will be capable of obtaining continuous moderate resolution spectra from 2.5-36 microns at spectral resolutions of about 2500 (2.5-20 microns) and 900 (20-36 microns). ASPIRE will also be able to obtain high resolution spectra (resolutions of 25,000) over selected windows in the 3.1-18 micron region. The ASPIRE suite of instruments provides the ability to study both gas-phase and solid-state materials in space. The PI for the mission is Scott Sandford and major mission partners include NASA-Ames, JPL, and Ball Aerospace.

  11. Life in ice: implications to astrobiology

    NASA Astrophysics Data System (ADS)

    2009-08-01

    During previous research expeditions to Siberia, Alaska and Antarctica, it was observed that glaciers and ice wedges contained bacterial cells that became motile as soon as the ice melted. This phenomenon of live bacteria in ice was first documented for microbes in ancient ice cores from Vostok, Antarctica. The first validly published species of Pleistocene bacteria alive on Earth today was Carnobacterium pleistocenium. This extremophile had remained for 32,000 years, encased in ice recently exposed in the Fox Tunnel of Alaska. These frozen bacteria began to swim as soon as the ice was thawed. Dark field microscopy studies revealed that large numbers of bacteria exhibited motility as soon as glacial ice was melted during our recent Expeditions to Alaska and Antarctica led to the conclusion that microbial life in ice was not a rare phenomenon. The ability of bacteria to remain alive while frozen in ice for long periods of time is of great significance to Astrobiology. In this paper, we describe the recent observations and advance the hypothesis that life in ice provides valuable clues to how we can more easily search for evidence of life on the Polar Caps of Mars, comets and other icy bodies of our Solar System. It is suggested that cryopanspermia may have played a far more important role in Origin of Life on Earth and the distribution of Life throughout the Cosmos and than previously thought possible.

    In April of 1992 in Atlanta, Georgia, nearly 50 elementary and secondary educators and about 100 postsecondary educators convened to explore their common interests in the conference on precollege-university partnerships. This report summarizes the remarks and conclusions of speakers, panelists, and of attendees gathered in regional work groups. During the course of the conference, attendees heard from federal agencies and foundations which fund education-related projects and learned of their enthusiastic support of partnerships. In our national need to manage education and training resources wisely, these funding agents see partnership benefits such as renewed excitement for teaching at all levels, effective and technologically up-to-date in-service training, more and better-prepared high school graduates entering colleges, and a general enhancement of understanding among educators at all levels of teaching. As an added benefit, the partnership concept promotes discussion and understanding in an atmosphere of respect, appreciation, and self-esteem. Several hours of the conference were devoted to panels addressing five questions important to education coalitions. The panelists represented a wide variety of teaching levels, geographic locations, educational experiences, and ethnic groups.

    Planetariums have a long history of experimentation with audio and visuals to create new multimedia experiences. We report on a series of innovative experiences in the Gates Planetarium at the Denver Museum of Nature & Science in 2009-2011 combining live performances of music and navigation through scientific visualizations. The Life Out There productions featured a story showcasing astrobiology concepts at scales ranging from galactic to molecular, and told using VJ-ing of immersive visualizations and musical performances from the House Band to the Universe. Funded by the NASA Astrobiology Institute's JPL-Titan Team, these hour-long shows were broken into four separate themed musical movements, with an improvisatory mix of music, dome visuals, and spoken science narrative which resulted in no two performances being exactly alike. Post-performance dissemination is continuing via a recorded version of the performance available as a DVD and online streaming video. Written evaluations from visitors who were present at the live shows reveal high satisfaction, while one of the Life Out There concerts was used to inaugurate a new evening program to draw in a younger audience demographic to DMNS.

Because of the obvious technical and economical limitations on in situ planetary exploration, laboratory simulations are one of the most feasible research options to make advances both in planetary science and in developing a consistent description of the origin of life. With this objective in mind, we applied vacuum technology to the design of versatile vacuum chambers devoted to the simulation of planetary atmospheres' conditions. These vacuum chambers are able to simulate atmospheres and surface temperatures representative of the majority of planetary objects, and they are especially appropriate for studying the physical, chemical and biological changes induced in a particular sample by in situ irradiation or physical parameters in a controlled environment. Vacuum chambers are a promising potential tool in several scientific and technological fields, such as engineering, chemistry, geology and biology. They also offer the possibility of discriminating between the effects of individual physical parameters and selected combinations thereof. The implementation of our vacuum chambers in combination with analytical techniques was specifically developed to make feasible the in situ physico-chemical characterization of samples. Many wide-ranging applications in astrobiology are detailed herein to provide an understanding of the potential and flexibility of these experimental systems. Instruments and engineering technology for space applications could take advantage of our environment-simulation chambers for sensor calibration. Our systems also provide the opportunity to gain a greater understanding of the chemical reactivity of molecules on surfaces under different environments, thereby leading to a greater understanding of interface processes in prebiotic chemical reactions and facilitating studies of UV photostability and photochemistry on surfaces.

    2009-08-01

    The study of terrestrial geomicrobiology and its relationship to rock weathering processes is an essential tool in developing analogues for similar processes that may have occurred on Mars. Most studies of manganese-enhanced rock varnish have focused on samples taken from warm arid desert regions. Here, we examine samples obtained from eolian-abraded lava flows of the 4700-4800 m high Ashikule Basin in Tibet. Because it receives approximately 300 mm of precipitation annually, this site is nowhere near as dry as Atacama Desert locales. However, the dusty, sulfate-rich, high-altitude and high-UV flux environment of the Tibetan locale offers new insight into rock varnish formation processes in a terrestrial environment that displays some attributes similar to those expected on early Mars. Microprobe measurements reveal that Mn enhancements in varnish are two orders of magnitude above the dust source, but Fe is only enhanced by a factor of three. Manganese-enhancing bacterial forms are not abundant but are still approximately 3 times more common than in Mojave and Sonoran Desert varnishes. In addition to its occurrence in subaerial positions, Tibetan varnish also occurs in micron-scale "pods" enveloped by silica glaze and as remobilized constituents that have migrated into the underlying weathering rind. A lack of surficial Mn-rich varnish, therefore, might not imply the absence of varnish. In contrast to suggestions that silica glaze might be a good source of microbial fossils and a key to varnish formation, we did not observe any clear microfossil forms entombed in silica glaze; further, there is no gradation between varnish and silica glaze but only distinct contacts. %K Analogue, Astrobiology, Bacteria, Biomineralization, Desert varnish, Geomicrobiology, Life on Mars, Manganese enhancement, Rock coating, Rock varnish, Microstromatolite, Tibet, Weathering

  10. Investigation of Life in the Atacama Desert by Astrobiology Rover

    The Atacama Desert is the most arid region on Earth and in several ways analogous to Mars. It has been suggested that the interior of the desert is the most lifeless place on Earth, yet it is known that microorganisms exist on rocks and in soils where the desert meets the coastal range. The Life in the Atacama (LITA) project is investigating the distribution and diversity of life and habitats in the desert using an rover guided by a remote science team. The Atacama Desert presents an excellent analogue to Mars because it is extremely dry, but also, like Mars it experiences high levels of ultraviolet radiation due to its altitude and atmospheric transparency. The soils in the Atacama have been found to be particularly high in oxidants, which lead to the rapid breakdown of organic material. The result is that in some regions of desert almost no biogenic material can be found on the surface. To the benefit of analogue studies for Mars exploration, the desert visually resembles Mars as seen through rover cameras. For these reasons: aridity, ultraviolet radiation and soil composition we believe the Atacama is analogous to Mars and an excellent location for rover field experiments. To support our astrobiologic investigation, we have created a mobile robot, Zo, that makes the measurement of the distribution and diversity of microorganisms possible. Mobility is crucial as habitats are hypothesized to depend on locally variable conditions including moisture, solar flux, and rock/soil composition. The ability to traverse tens to hundreds of kilometers while deploying sensors is a fundamental requirement because only by visiting many sites will the few in which organisms exist be found. Many observations provide the basis for statistically valid analysis of distribution. Zo's instrument payload combines complementary elements, some directed towards remote sensing of the environment (geology, morphology, mineralogy, climate) for the detection of conditions favorable to

    The EASL Monothematic Conference on Translational Research in Viral Hepatitis brought together a group of leading scientists and clinicians working on both, basic and clinical aspects of viral hepatitis, thereby building bridges from bench to bedside. This report recapitulates the presentations and discussions at the conference held in Lyon, France on November 29-30, 2013. In recent years, great advances have been made in the field of viral hepatitis, particularly in hepatitis C virus (HCV) infection. The identification of IL28B genetic polymorphisms as a major determinant for spontaneous and treatment-induced HCV clearance was a seminal discovery. Currently, hepatologists are at the doorstep of even greater advances, with the advent of a wealth of directly acting antivirals (DAAs) against HCV. Indeed, promising results have accumulated over the last months and few years, showing sustained virological response (SVR) rates of up to 100% with interferon-free DAA combination therapies. Thus, less than 25 years after its identification, HCV infection may soon be curable in the vast majority of patients, highlighting the great success of HCV research over the last decades. However, viral hepatitis and its clinical complications such as liver cirrhosis and hepatocellular carcinoma (HCC) remain major global challenges. New therapeutic strategies to tackle hepatitis B virus (HBV) and hepatitis D virus (HDV) infection are needed, as current therapies have undeniable limitations. Nucleoside/nucleotide analogues (NUC) can efficiently control HBV replication and reduce or even reverse liver damage. However, these drugs have to be given for indefinite periods in most patients to maintain virological and biochemical responses. Although sustained responses off treatment can be achieved by treatment with (pegylated) interferon-α, only about 10-30% of patients effectively resolve chronic hepatitis B. It was the goal of this conference to review the progress made over the last

    The New York Center for Astrobiology (NYCA) EPO effort is a collaboration combining expertise in evaluation and assessment of STEM educational modules with disciplinary expertise in astrobiology. In practice, the NYCA partners with external experts in professional development, informal education and evaluation to assist in developing and implementing certain programs of the NYCA EPO activities. Two specific program initiatives of the NYCA EPO effort offer excellent examples of programs with strong science content knowledge as well as using effective tools to address the NSF impact categories. These are the ExxonMobil Bernard Harris Summer Science Camp (EMBHSSC, in conjunction with RPI's STEM Pipeline Initiative) and the Astrobiology Teachers Academy (ATA). The EMBHSSC for middle school students focuses on NASA astrobiology initiatives around the "Quest for Life" theme. The Camp has a comprehensive evaluation component and uses pre-and post- assessment of student knowledge and interest in STEM. Recent data suggest that every student has shown a measurable gain in these areas. The ATA is a weeklong summer intensive professional development program for P-12 STEM teachers that combines discipline scientists in the NYCA with an external evaluation organization, the Association for the Cooperative Advancement of Science and Education (ACASE). The goal is for teachers to develop a new learning module for a course they teach that uses astrobiology as a content focus to engage students. The Academy has scientists collaborating with teachers in this effort, providing content and assistance in designing instructional activities. Assessments are woven into the fabric of the work in a few ways: 1. There is a purposeful focus on assessment as part of the learning module, and the content of the ATA; 2. ACASE offers teachers a tool for tracking their students' attainment of the learning goals identified in their learning module; 3. There are daily evaluations of the teachers

    Abstract The landscape of Mars, despite its apparent hostility to life, is riddled with geological and mineralogical signs of past or present hydrological activity. As such, it is a key target for astrobiological exploration. There are, however, many factors that will need to be considered when planning in-situ and sample return missions, if these missions are indeed to adequately exploit the science potential of this intriguing world. These will not only take into account the environment of the landing site in terms of topography and ambient atmosphere etc., but also the geochemical make up of the surface regolith, evidence of hydrological processes and various other considerations. The knowledge base in all aspects of Martian science is being added to on an almost daily basis, and the aim of this work is to combine data and studies to nominate top priority landing locations for the search for evidence of life on Mars. We report in particular on science and technical criteria and our data analysis for sites of astrobiological interest. This includes information from previous missions (such as Mars Express, MGS, Odyssey, MRO and MER rovers) on mineralogical composition, geomorphology, evidence from past water history from imaging and spectroscopic data, and existence of in-situ prior information from landers and rovers (concerning evidences for volatiles, organics and habitability conditions). We discuss key mission objectives, and assess what sort of sites should be targeted in the light of these. We consider the accessibility of chosen locations, taking into account difficulties presented in accessing the polar regions and other regions of high altitude. We describe what additional measurements are needed, and outline the technical and scientific operations requirements of such in-situ landers and sample return missions. Approach In the first step of this study we focus on the science objectives of in-situ and sample return missions to Mars. We investigate the

    During the 2008 Tawani International Expedition Schirmacher Oasis/Lake Untersee Antarctica Expedition, living and instantly motile bacteria were found in freshly thawed meltwater from ice of the Schirmacher Oasis Lakes, the Anuchin Glacier ice and samples of the that perennial ice sheet above Lake Untersee. This phenomenon of living bacteria encased in ice had previously been observed in the 32,000 year old ice of the Fox Tunnel. The bacteria found in this ice included the strain FTR1T which was isolated and published as valid new species (Carnobacterium pleistocenium) the first validly published living Pleistocene organism still alive today. Living bacteria were also extracted from ancient ice cores from Vostok, Antarctica. The discovery that many strains of bacteria are able to survive and remain alive while frozen in ice sheets for long periods of time may have direct relevance to Astrobiology. The abundance of viable bacteria in the ice sheets of Antarctica suggests that the presence of live bacteria in ice is common, rather than an isolated phenomenon. This paper will discuss the results of recent studies at NSSTC of bacteria cryopreserved in ice. This paper advances the hypothesis that cryopreserved cells, and perhaps even viable bacterial cells, may exist today--frozen in the water-ice of lunar craters, the Polar Caps or craters of Mars; or in the permafrost of Mars; ice and rocks of comets or water bearing asteroids; or in the frozen crusts of the icy moons of Jupiter and Saturn. The existence of bacterial life in ice suggests that it may not be necessary to drill through a thick ice crust to reach liquid water seas deep beneath the icy crusts of Europa, Ganymede and Enceladus. The presence of viable bacteria in the ice of the Earth s Polar Caps suggests that the possibility that cryo-panspermia (i.e., the trans-planetary transfer of microbial life by impact ejection/spallation of bacteria-rich polar ice masses) deserves serious consideration and study as a

    We have developed the space suit simulator Aouda.X, which is capable of reproducing the physical and sensory limitations a flight-worthy suit would have on Mars. Based upon a Hard-Upper-Torso design, it has an advanced human-machine interface and a sensory network connected to an On-Board Data Handling system to increase the situational awareness in the field. Although the suit simulator is not pressurized, the physical forces that lead to a reduced working envelope and physical performance are reproduced with a calibrated exoskeleton. This allows us to simulate various pressure regimes from 0.3-1 bar. Aouda.X has been tested in several laboratory and field settings, including sterile sampling at 2800 m altitude inside a glacial ice cave and a cryochamber at -110°C, and subsurface tests in connection with geophysical instrumentation relevant to astrobiology, including ground-penetrating radar, geoacoustics, and drilling. The communication subsystem allows for a direct interaction with remote science teams via telemetry from a mission control center. Aouda.X as such is a versatile experimental platform for studying Mars exploration activities in a high-fidelity Mars analog environment with a focus on astrobiology and operations research that has been optimized to reduce the amount of biological cross contamination. We report on the performance envelope of the Aouda.X system and its operational limitations. PMID:22300413

    Infrared spectroscopy in the 2.5-16 micron range is a principle means by which organic compounds are detected and identified in space. Ground-based, airborne, and spaceborne IR spectral studies have already demonstrated that a significant fraction of the carbon in the interstellar medium (ISM) resides in the form of complex organic molecular species. Unfortunately, neither the distribution of these materials nor their genetic and evolutionary relationships with each other or their environments are well understood. The Astrobiology Explorer (ABE) is a MIDEX mission concept currently under study at NASA's Ames Research Center in collaboration with Ball Aerospace and Technologies Corporation. ABE will conduct IR spectroscopic observations to address outstanding important problems in astrobiology, astrochemistry, and astrophysics. The core observational program would make fundamental scientific progress in understanding (1) the evolution of ices and organic matter in dense molecular clouds and young forming stellar systems, (2) the chemical evolution of organic molecules in the ISM as they transition from AGB outflows to planetary nebulae to the general diffuse ISM to H II regions and dense clouds, (3) the distribution of organics in the diffuse ISM, (4) the nature of organics in the Solar System (in comets, asteroids, satellites), and (5) the nature and distribution of organics in local galaxies. The technical considerations of achieving these science objectives in a MIDEX-sized mission will be described.

    Example MST activities examined here show: (1) an inquiry-driven learning stimulus, involving (2) the synthesis of concepts in math, science and technology, through (3) the application of the scientific method and engineering problem solving/test protocols, and provoking (4) a stimulus for further exploration. A semi-exploratory learning approach offered background aimed at enabling participants to take meaningful courses of investigation; this approach must be balanced by maintaining contact with framework content standards. On the whole, the philosophy underlying the MST learning approach--as envisioned in the draft NYS Framework, and embodied in the example activities--is strongly endorsed. This endorsement is broad-based: those represented include teachers of mathematics, science, and technology, and school district administrators--in roughly equal numbers. Discussion centers not on whether the MST approach should be pursued, but on what is involved in doing it. Teams of conference participants were given time to plan or extend MST initiatives in their own districts. Outlines of the initiatives proposed by ten of the teams are disseminated herein.

    We describe the field demonstration of astrobiology instruments and research methods conducted in and from the Mars Desert Research Station (MDRS) in Utah during the EuroGeoMars campaign 2009 coordinated by ILEWG, ESA/ESTEC and NASA Ames, with the contribution of academic partners. We discuss the entire experimental approach from determining the geological context using remote sensing, in situ measurements, sorties with sample collection and characterization, analysis in the field laboratory, to the post sample analysis using advanced laboratory facilities. We present the rationale for terrestrial field campaigns to strengthen astrobiology research and the link between in situ and orbital remote sensing data. These campaigns are supporting the preparation for future missions such as Mars Science Laboratory, ExoMars or Mars Sample Return. We describe the EuroGeoMars 2009 campaign conducted by MDRS crew 76 and 77, focused on the investigation of surface processes in their geological context. Special emphasis was placed on sample collection and pre-screening using in-situ portable instruments. Science investigations included geological and geochemical measurements as well as detection and diagnostic of water, oxidants, organic matter, minerals, volatiles and biota. EuroGeoMars 2009 was an example of a Moon-Mars field research campaign dedicated to the demonstration of astrobiology instruments and a specific methodology of comprehensive measurements from selected sampling sites. We discuss in sequence: the campaign objectives and trade-off based on science, technical or operational constraints. This includes remote sensing data and maps, and geological context; the monitoring of environmental parameters; the geophysical context and mineralogy studies; geology and geomorphology investigations; geochemistry characterization and subsurface studies. We describe sample handling (extraction and collection) methods, and the sample analysis of soils and rocks performed in the

    Sample Analysis at Mars (SAM) is a suite of instruments that will be onboard the Mars Science Laboratory (MSL) rover, which was recently named Curiosity in a student-naming contest. SAM's three instruments are devoted to studying the chemical composition of the Martian surface and atmosphere and to understanding the planet's past habitability and potential habitability today. Curiosity is scheduled to launch in 2011, however many Education and Public Outreach (EPO) activities supported by the MSL mission are well underway. The SAM EPO plan includes elements of both formal and informal education in addition to outreach, such as incorporating data into the Mars Exploration Student Data Teams program, developing a museum exhibit and associated educational materials about SAM's research, and writing articles about the MSL mission and SAM's findings for ChemMatters magazine. One of the EPO projects currently being carried out by members of the SAM team is training secondary education teachers in Mars geology, astrobiology, and SAM science goals via professional development workshops. Several of the recent Mars missions have had extensive EPO components to them. As a result, numerous educational activities and resources have already been developed relating to understanding Mars and astrobiology. We have conducted a survey of these activities and resources previously created and have compiled those relevant and useful for our SAM teacher training workshops. Resources and activities have been modified as needed. In addition, we have identified areas in which no educational activities exist and are developing new curriculum specifically to address these gaps. This work is funded by the MN Space Grant Consortium and NASA's Science Mission Directorate.

    Biogeochemistry investigates chemical cycles which influence or are influenced by biological activity. Astrobiology studies the origin, evolution and distribution of life in the universe. The biogeochemical Fe cycle has controlled major nutrient cycles such as the C cycle throughout geological time. Iron sulfide minerals may have provided energy and surfaces for the first pioneer organisms on Earth. Banded iron formations document the evolution of oxygenic photosynthesis. To assess the potential habitability of planets other than Earth one looks for water, an energy source and a C source. On Mars, for example, Fe minerals have provided evidence for the past presence of liquid water on its surface and would provide a viable energy source. Here we present Mössbauer spectroscopy investigations of Fe and C cycle interactions in both ancient and modern environments. Experiments to simulate the diagenesis of banded iron formations indicate that the formation of ferrous minerals depends on the amount of biomass buried with ferric precursors rather than on the atmospheric composition at the time of deposition. Mössbauer spectra further reveal the mutual stabilisation of Fe-organic matter complexes against mineral transformation and decay of organic matter into CO2. This corresponds to observations of a `rusty carbon sink' in modern sediments. The stabilisation of Fe-organic matter complexes may also aid transport of particulate Fe in the water column while having an adverse effect on the bioavailability of Fe. In the modern oxic ocean, Fe is insoluble and particulate Fe represents an important source. Collecting that particulate Fe yields small sample sizes that would pose a challenge for conventional Mössbauer experiments. We demonstrate that the unique properties of the beam used in synchrotron-based Mössbauer applications can be utilized for studying such samples effectively. Reactive Fe species often occur in amorphous or nanoparticulate form in the environment and

    Introduction Nothing has been published to describe the practices of medical societies in choosing abstracts for presentations at their annual meetings. We surveyed medical societies to determine their practices, and also present a theoretical analysis of the topic. Methods We contacted a convenience sample of large U.S. medical conferences, and determined their approach to choosing abstracts. We obtained information from web sites, telephone, and email. Our theoretical analysis compares values-based and empirical approaches for scoring system development. Results We contacted 32 societies and obtained data on 28 (response rate 88%). We excluded one upon learning that research was not presented at its annual meeting, leaving 27 for analysis. Only 2 (7%) made their abstract scoring process available to submitters. Reviews were blinded in most societies (21;78%), and all but one asked reviewers to recuse themselves for conflict of interest (96%). All required ≥3 reviewers. Of the 24 providing information on how scores were generated, 21 (88%) reported using a single gestalt score, and three used a combined score created from pooled domain-specific sub-scores. We present a framework for societies to use in choosing abstracts, and demonstrate its application in the development of a new scoring system. Conclusions Most medical societies use subjective, gestalt methods to select research for presentation at their annual meetings and do not disclose to submitters the details of how abstracts are chosen. We present a new scoring system that is transparent to submitters and reviewers alike with an accompanying statement of values and ground rules. We discuss the challenges faced in selecting abstracts for a large scientific meeting and share the values and practical considerations that undergird the new system. PMID:26265966

    After the realization of the International Space Station, human exploratory missions to Moon or Mars, i.e. beyond low Earth orbit, are widely considered as the next logical step of peaceful cooperation in space on a global scale. Besides the human desire to extend the window of habitability, human exploratory missions are driven by several aspects of science, technology, culture and economy. Mars is currently considered as a major target in the search for life beyond the Earth. Understanding the history of water on Mars appears to be one of the clues to the puzzle on the probability of life on Mars. On Earth microorganisms have flourished for more than 3.5 Ga and have developed strategies to cope with so-called extreme conditions (e.g., hot vents, permafrost, subsurface regions, rocks or salt crystals). Therefore, in search for life on Mars, microorganisms are the most likely candidates for a putative biota on Mars and the search for morphological or chemical signatures of life or its relics is one of the primary and most exciting goals of Mars exploration. The presence of humans on the surface of Mars will substantially increase this research potential, e.g., by supporting deep subsurface drilling and by allowing intellectual collection and sophisticated in situ analysis of samples of astrobiological interest. On the other hand, such long-duration missions beyond LEO will add a new dimension to human space flight, concerning the distance of travel, the radiation environment, the gravity levels, the duration of the mission, and the level of confinement and isolation the crew will be exposed to. This will raise the significance of several health issues, above all radiation protection, gravity related effects as well as psychological issues. Furthermore, the import of internal and external microorganisms inevitably accompanying any human mission to Mars, or brought purposely to Mars as part of a bioregenerative life support system needs careful consideration with

    Software supporting an online conference series was developed with the purpose of catalyzing interdisciplinary investigations in Sun-Earth system science among large groups of researchers worldwide in celebration of the 50th anniversary of the International Geophysical Year in 2007. Transformative science in this area lies at the edges and intersections of individual elements (the Sun, heliosphere, magnetosphere, ionosphere and atmosphere) whose collective behavior determines the global system response. Continuing progress requires access to a vast developing cyber-infrastructure of large international data sets, high performance computing and advanced visualization. However, it also requires the development of new tools that bring these advances into contact with groups of interdisciplinary and international researchers so they can be used to attack grand challenge science issues in a manner not previously possible. This presentation describes the results of an eGY showcase project to develop a testbed online conference series for this purpose. The conference series is a collaborative effort between the CAWSES, IHY, eGY, ICESTAR, NASA/LWS and NSF Atmospheric Sciences Programs. Lessons learned in developing this first interface, as well as a discussion of key elements and how they worked will be presented.

    There is a growing awareness to the need for moving away from lecture--mode approaches in undergraduate STEM education and to the importance of increasing innovation and diversity in STEM education programs. We adopt the case--studies approach, and have taught an introductory course on astrobiology ---the science of life in the universe--- at the University of Alabama in Huntsville. We have created teaching materials using different types of cases, and have conducted an evaluation study. We intend to refine our teaching materials based on the evaluation study, and repeat the course next year. Following this study the teaching materials will be made available free of charge to any instructor, and the approach will be applied to other disciplines, including large enrollment classes.

    Lichens are symbioses of two organisms, a fungal mycobiont and a photoautotrophic photobiont. In nature, many lichens tolerate extreme environmental conditions and thus became valuable models in astrobiological research to fathom biological resistance towards non-terrestrial conditions; including space exposure, hypervelocity impact simulations as well as space and Martian parameter simulations. All studies demonstrated the high resistance towards non-terrestrial abiotic factors of selected extremotolerant lichens. Besides other adaptations, this study focuses on the morphological and anatomical traits by comparing five lichen species— Circinaria gyrosa, Rhizocarpon geographicum, Xanthoria elegans, Buellia frigida, Pleopsidium chlorophanum—used in present-day astrobiological research. Detailed investigation of thallus organization by microscopy methods allows to study the effect of morphology on lichen resistance and forms a basis for interpreting data of recent and future experiments. All investigated lichens reveal a common heteromerous thallus structure but diverging sets of morphological-anatomical traits, as intra-/extra-thalline mucilage matrices, cortices, algal arrangements, and hyphal strands. In B. frigida, R. geographicum, and X. elegans the combination of pigmented cortex, algal arrangement, and mucilage seems to enhance resistance, while subcortex and algal clustering seem to be crucial in C. gyrosa, as well as pigmented cortices and basal thallus protrusions in P. chlorophanum. Thus, generalizations on morphologically conferred resistance have to be avoided. Such differences might reflect the diverging evolutionary histories and are advantageous by adapting lichens to prevalent abiotic stressors. The peculiar lichen morphology demonstrates its remarkable stake in resisting extreme terrestrial conditions and may explain the high resistance of lichens found in astrobiological research.

    The Life In The Atacama (LITA) project has developed and field tested a long-range, solar-powered, automated rover platform (Zoe) and a science payload assembled to search for microbial life in the Atacama desert. Life is hardly detectable over most of the extent of the driest desert on Earth. Its geological, climatic, and biological evolution provides a unique training ground for designing and testing exploration strategies and life detection methods for the robotic search for life on Mars. LITA opens the path to a new generation of rover missions that will transition from the current study of habitability (MER) to the upcoming search for, and study of, habitats and life on Mars. Zoe's science payload reflects this transition by combining complementary elements, some directed towards the remote sensing of the environment (geology, morphology, mineralogy, weather/climate) for the detection of conditions favorable to microbial habitats and oases along survey traverses, others directed toward the in situ detection of life' signatures (biological and physical, such as biological constructs and patterns). New exploration strategies specifically adapted to the search for microbial life were designed and successfully tested in the Atacama between 2003-2005. They required the development and implementation in the field of new technological capabilities, including navigation beyond the horizon, obstacle avoidance, and "science-on-the-fly" (automated detection of targets of science value), and that of new rover planning tools in the remote science operation center.

    Meteorites will remain the most accessible, most diverse and most abundant source of extraterrestrial materials for many years to come. New sources of large numbers of meteorites allow the recovery of rare types particularly relevant for astrobiology, including Martian and Lunar samples. Oman has become an important source of meteorites only since 1999. Conditions for search and recovery are particularly favourable in many areas here because of an abundance of flat, light-colored, sand- and vegetation-free surfaces. During search expeditions carried out in the central deserts of Oman in 2001-2003 large numbers of meteorites, including a Martian and a Lunar sample, were recovered. The mass of recovered meteorites is 1334 kg, corresponding to approximately 150 to 200 fall events. We aim to classify all recovered specimens and study pairing and weathering effects. Our expeditions demonstrate the possibility to recover meteorite samples with astrobiological relevance with modest investments of finances and manpower.

    Scalice, Daniella

    The mission statement of the NASA Astrobiology Institute (NAI) charts a course to establishing astrobiology as a new and influential field of scientific inquiry. It integrates world class, interdisciplinary research with training for the next generation of astrobiologists. It enables collaboration between distributed research teams by prioritizing the use of modern information technologies, and empowers astrobiologists to provide leadership for space missions. But this unique vision would not have been complete without the inclusion of an Education and Public Outreach (E/PO) program. Over the past ten years, NAI's E/PO program has taken shape - from bootstrapping in the early days, to partnering with the likes of Disney and PBS - in pursuit of inspiring young people onto the scientific path. The E/PO program's highly collaborative group of education specialists has worked with museums, national parks, filmmakers, radio broadcasters, families, teachers, and students to ensure that the bright young faces of today find themselves in the labs of tomorrow's astrobiologists.

    The Georgia Tech Center for Ribosome Adaptation and Evolution, a center funded by the NASA Astrobiology Institute, developed an educational Astrobiology program titled, “Life on the Edge: Astrobiology.” The purpose of the program was to provide educators with the materials, exposure, and skills necessary to prepare our future workforce and to foster student interest in scientific discovery on Earth and throughout the universe. A one-week, non-residential summer enrichment program for high school students was conducted and tested by two high school educators, an undergraduate student, and faculty in the Schools of Biology, and Chemistry and Biochemistry at Georgia Tech. In an effort to promote and encourage entry into teaching careers, Georgia Tech paired in-service teachers in the Georgia Intern-Fellowship for Teachers (GIFT) program with an undergraduate student interested in becoming a teacher through the Tech to Teaching program. The GIFT and Tech to Teaching fellows investigated extremophiles which have adapted to life under extreme environmental conditions. As a result, extremophiles became the focus of a week-long, “Life on the Edge: Astrobiology” curriculum aligned with the Georgia Performance Standards in Biology. Twenty-five high school students explored the adaptation and survival rates for various types of extremophiles exposed to UV radiation and desiccation; students were also introduced to hands-on activities and techniques such as genomic DNA purification, gel electrophoresis, and Polymerase Chain Reaction (PCR). The impact on everyone invested and involved in the Astrobiology program including the GIFT and Tech to Teaching fellows, high school students, and faculty are discussed.

    2013-04-01

    Case studies is a well known and widely used method in law schools, medical schools, and business schools, but relatively little used in physics or astronomy courses. We developed an astrobiology course based strongly on the case studies approach, and after teaching it first at the University of Alabama in Huntsville, we have adapted it and are now teaching it at Alabama A&M University, a HBCU. The case studies approach uses several well tested and successful teaching methods - including group work, peer instruction, current interest topics, just-in-time teaching, &c. We have found that certain styles of cases are more popular among students than other styles, and will revise our cases to reflect such student preferences. We chose astrobiology -- an inherently multidisciplinary field -- because of the popularity of the subject matter, its frequent appearance in the popular media (news stories about searches for life in the universe, the discovery of Earth-like exoplanets, etc, in addition to SciFi movies and novels), and the rapid current progress in the field. In this talk we review briefly the case studies method, the styles of cases used in our astrobiology course, and student response to the course as found in our assessment analysis.

    NASA's Organism/Organic Exposure to Orbital Stresses, or O/OREOS, nanosatellite is a sci-ence demonstration mission that showcases achievements in using hardware from a technology development program led by the Small Spacecraft Division at NASA's Ames Research Center, Moffett Field, California. Continuing Ames' development of triple-cube nanosatellite tech-nology and flight systems, which includes the successful GeneSat-1 and PharmaSat missions, O/OREOS is constructed from off-the-shelf commercial and NASA-designed parts to create a fully self-contained, automated, stable, light-weight space science laboratory with innovative environment and power control techniques; sensors to monitor the levels of pressure, temper-ature, humidity, radiation and acceleration; and a communications system able to regularly accept commands from the ground and transmit data back to Earth for scientific analysis. The overall goal of the O/OREOS mission is to demonstrate the capability to do low-cost sci-ence experiments on autonomous nanosatellites in space in support of the Astrobiology Small Payloads program under the Planetary Science Division of the Science Mission Directorate at NASA Headquarters. The spacecraft houses two science payloads: the Space Environment Viability of Organics (SEVO) experiment will monitor the stability and changes in four classes of organic matter (results presented at another COSPAR session); and the Space Environment Survivability of Live Organisms (SESLO) experiment (presented here). SESLO will charac-terize the growth, activity, health, and ability of microorganisms to adapt to the stresses of the space environment. The experiment is sealed in a vessel at one atmosphere and contains two types of microbes commonly found in salt ponds and soil, in a dried and dormant state: Halorubrum chaoviator and Bacillus subtilis. After it reaches orbit, the experiment will initiate and begin to rehydrate and grow three sets of the microbes at three different times

    Sargeant, Marcel Andre Almont

    Problem. Science education has long been a great concern in the United States, where less than one-third of the students perform at or above the proficient level. The purpose of this study was to investigate the status of the science program in a selected Union Conference of the Seventh-day Adventist school system. Specifically, this study investigated the perceptions of teachers and students regarding the extent to which the science program meets the criteria of the National Commission on Mathematics and Science Teaching for the 21st century and to what extent these criteria are related to academic performance as indicated by Iowa Test of Basic Skills (ITBS) science scores. Method. Two questionnaires designed by the researcher were used to get responses from 424 students in seventh and eighth grades and 68 teachers to see how this school system compares to the criteria of National Commission on Mathematics and Science Teaching for the 21 st century. Three classroom configurations were investigated in this study, namely: (a) multigrade, (b) two-grade, and (c) single-grade. Crosstabulation, one-way analysis of variance, Kruskal-Wallis test, and linear regression were used to analyze the four research questions of this study. Results. The single-grade classroom configuration received a better rating for the science criteria (p < 0.01), and students from single-grade performed significantly better than two-grade/multigrade (p < 0.01) classroom configurations on their science achievement (ITBS). There were significant relationships among science achievement and the factors that measured the criteria of the National Commission for Mathematics and Science Teaching for the 21st century. Conclusions. The differences in teaching practices explained the discrepancies in the three classroom configurations. Schools can therefore develop policies and strategies to improve the practices in the teaching and learning process in science education that were identified as being

    Scientific ground-truth measurements for near-term Mars missions, such as the 2009 Mars Science Laboratory (MSL) mission, are essential for validating current in situ flight instrumentation and for the development of advanced instrumentation technologies for life-detection missions over the next decade. The NASA Astrobiology Institute (NAI) has recently funded a consortium of researchers called the Astrobiology Sample Analysis Program (ASAP) to analyze an identical set of homogenized martian analog materials in a "round-robin" style using both state-of-the-art laboratory techniques as well as in-situ flight instrumentation including the SAM gas chromatograph mass spectrometer and CHEMIN X-ray diffraction/fluorescence instruments on MSL and the Urey and MOMA organic analyzer instruments under development for the 2013 ExoMars missions. The analog samples studied included an Atacama Desert soil from Chile, the Murchison meteorite, a gypsum sample from the 2007 AMASE Mars analog site, jarosite from Panoche Valley, CA, a hydrothermal sample from Rio Tinto, Spain, and a "blind" sample collected during the 2007 MSL slow-motion field test in New Mexico. Each sample was distributed to the team for analysis to: (1) determine the nature and inventory of organic compounds, (2) measure the bulk carbon and nitrogen isotopic composition, (3) investigate elemental abundances, mineralogy and matrix, and (4) search for biological activity. The experimental results obtained from the ASAP Mars analog research consortium will be used to build a framework for understanding the biogeochemistry of martian analogs, help calibrate current spaceflight instrumentation, and enhance the scientific return from upcoming missions.

    What might be the likely impact of confirmed discovery of extraterrestrial life—microbial or intelligent life—on terrestrial religion? Many have speculated that the anthropo-centrism and earth-centrism which allegedly have characterized our religious traditions would be confronted with a crisis. Would new knowledge that we are not alone in the universe lead to a collapse of traditional religious belief? This presentation will summarize the results of the Peters Religious Crisis Survey of 1325 respondents. This survey shows that the majority of adherents to Christianity, Islam, Judaism, and Buddhism demonstrate little or no anxiety regarding the prospect of contact with extraterrestrial life, even if they express some doubts regarding their respective religious tradition and the traditions of others. This presentation will also show that theological speculation regarding other worlds has sparked lively debate beginning as far back as the middle ages and continuing into our present era. Ted Peters is a research and teaching scholar with the Center for Theology and the Natural Sciences at the Graduate Theological Union in Berkeley, California. He is co-editor of the journal, Theology and Science, and author of the books, The Evolution of Terrestrial and Extraterrestrial Life (Pandora 2008) and Playing God?

    The 18th Maternal and Child Health (MCH) Epidemiology and 22nd CityMatCH MCH Urban Leadership Conference took place in December 2012, covering MCH science, program, and policy issues. Assessing the impact of the Conference on attendees' work 6 months post-Conference provides information critical to understanding the impact and the use of new partnerships, knowledge, and skills gained during the Conference. Evaluation assessments, which included collection of quantitative and qualitative data, were administered at two time points: at Conference registration and 6 months post-Conference. The evaluation files were merged using computer IP address, linking responses from each assessment. Percentages of attendees reporting Conference impacts were calculated from quantitative data, and common themes and supporting examples were identified from qualitative data. Online registration was completed by 650 individuals. Of registrants, 30 % responded to the 6 month post-Conference assessment. Between registration and 6 month post-Conference evaluation, the distribution of respondents did not significantly differ by organizational affiliation. In the 6 months following the Conference, 65 % of respondents reported pursuing a networking interaction; 96 % shared knowledge from the Conference with co-workers and others in their agency; and 74 % utilized knowledge from the Conference to translate data into public health action. The Conference produced far-reaching impacts among Conference attendees. The Conference served as a platform for networking, knowledge sharing, and attaining skills that advance the work of attendees, with the potential of impacting organizational and workforce capacity. Increasing capacity could improve MCH programs, policies, and services, ultimately impacting the health of women, infants, and children. PMID:25107597

    The influence of Free and Open Source Software (FOSS) projects on Earth and Space Science Informatics (ESSI) continues to grow, particularly in the emerging context of Data Science or Open Science. The scientific significance and heritage of FOSS projects is only to a limited amount covered by traditional scientific journal articles: Audiovisual conference recordings contain significant information for analysis, reference and citation. In the context of data driven research, this audiovisual content needs to be accessible by effective search capabilities, enabling the content to be searched in depth and retrieved. Thereby, it is ensured that the content producers receive credit for their efforts within the respective communities. For Geoinformatics and ESSI, one distinguished driver is the OSGeo Foundation (OSGeo), founded in 2006 to support and promote the interdisciplinary collaborative development of open geospatial technologies and data. The organisational structure is based on software projects that have successfully passed the OSGeo incubation process, proving their compliance with FOSS licence models. This quality assurance is crucial for the transparent and unhindered application in (Open) Science. The main communication channels within and between the OSGeo-hosted community projects for face to face meetings are conferences on national, regional and global scale. Video recordings have been complementing the scientific proceedings since 2006. During the last decade, the growing body of OSGeo videos has been negatively affected by content loss, obsolescence of video technology and dependence on commercial video portals. Even worse, the distributed storage and lack of metadata do not guarantee concise and efficient access of the content. This limits the retrospective analysis of video content from past conferences. But, it also indicates a need for reliable, standardized, comparable audiovisual repositories for the future, as the number of OSGeo projects

    One of the principal means by which organic compounds are detected and identified in space is by infrared spectroscopy. Past IR telescopic and laboratory studies have shown that much of the carbon in the interstellar medium (ISM) is in complex organic species but the distribution, abundance and evolutionary relationships of these materials are not well understood. The Astrobiology Explorer (ABE) is a MIDEX mission concept designed to conduct IR spectroscopic observations to detect and identify these materials and address outstanding problems in astrobiology, astrochemistry, and astrophysics. ABE's core science program includes observations of planetary nebulae and stellar outflows, protostellar objects, Solar System objects, and galaxies, and lines of sight through dense molecular clouds and the diffuse ISM. ABE is a cryogenically-cooled 60 cm diameter space telescope equipped with 3 cross-dispersed R-2000 spectrometers that share a single common slit. Each spectrometer measures one spectral octave and together cover the entire 2.5-20 micron region simultaneously. The spectrometers use state-of-the-art InSb and Si:As 1024x1024 pixel detectors. ABE would operate in a heliocentric, Earth drift-away orbit and have a core science mission lasting approximately 1.5 years. ABE is currently under study at NASA's Ames Research Center in collaboration with Ball Aerospace and Technologies Corp.

    During our five years as an NAI charter member, Arizona State University sponsored a broadly-based program of research and training in Astrobiology to address the origin, evolution and distribution of life in the Solar System. With such a large, diverse and active team, it is not possible in a reasonable space, to cover all details of progress made over the entire five years. The following paragraphs provide an overview update of the specific research areas pursued by the Arizona State University (ASU) Astrobiology team at the end of Year 5 and at the end of the 4 month and subsequent no cost month extensions. for a more detailed review, the reader is referred to the individual annual reports (and Executive Summaries) submitted to the NAI at the end of each of our five years of membership. Appended in electronic form is our complete publication record for all five years, plus a tabulation of undergraduates, graduate students and post-docs supported by our program during this time. The overarching theme of ASU s Astrobiology program was "Exploring the Living Universe: Studies of the Origin, Evolution and Distribution of Life in the Solar System". The NAi-funded research effort was organized under three basic sub- themes: 1. Origins of the Basic Building Blocks of Life. 2. Early Biosphere Evolution. and 3. Exploring for Life in the Solar System. These sub-theme areas were in turn, subdivided into Co-lead research modules. In the paragraphs that follow, accomplishments for individual research modules are briefly outlined, and the key participants presented in tabular form. As noted, publications for each module are appended in hard copy and digital formats, under the name(s) of lead co-Is.

    Extremophiles are organisms adapted to grow at extreme ranges of environmental variables, such as high or low temperatures, acid or alkaline medium, high salt concentration, high pressures and so forth. Most extremophiles are micro-organisms that belong to the Archaea and Bacteria domains, and are widely spread across the world, which include the polar regions, volcanoes, deserts, deep oceanic sediments, hydrothermal vents, hypersaline lakes, acid and alkaline water bodies, and other extreme environments considered hostile to human life. Despite the tropical climate, Brazil has a wide range of ecosystems which include some permanent or seasonally extreme environments. For example, the Cerrado is a biome with very low soil pH with high Al+3 concentration, the mangroves in the Brazilian coast are anaerobic and saline, Pantanal has thousands of alkaline-saline lakes, the Caatinga arid and hot soils and the deep sea sediments in the Brazilian ocean shelf. These environments harbour extremophilic organisms that, coupled with the high natural biodiversity in Brazil, could be explored for different purposes. However, only a few projects in Brazil intended to study the extremophiles. In the frame of astrobiology, for example, these organisms could provide important models for defining the limits of life and hypothesize about life outside Earth. Brazilian microbiologists have, however, studied the extremophilic micro-organisms inhabiting non-Brazilian environments, such as the Antarctic continent. The experience and previous results obtained from the Brazilian Antarctic Program (PROANTAR) provide important results that are directly related to astrobiology. This article is a brief synopsis of the Brazilian experience in researching extremophiles, indicating the most important results related to astrobiology and some future perspectives in this area.

    The Astrobiology Explorer (ABE) is a Medium-Class Explorer (MIDEX) mission concept currently under study at NASA's Ames Research Center. ABE will conduct infrared (IR) spectroscopic observations with much better sensitivity than Infrared Space Observatory (ISO) or the Stratospheric Observatory for Infrared Astronomy program (SOFIA) in order to address outstanding astrobiologically important problems in astrochemistry as well as important astrophysical investigations. The core observational astrobiology program would make fundamental scientific progress in understanding the cosmic history of molecular carbon, the distribution of organic matter in the diffuse interstellar medium, tracing the chemical history of complex organic molecules in the interstellar medium, and the evolution of organic ices in young planetary systems. The ABE instrument concept includes a 0.5 m aperture Cassegrain telescope and a suite of three moderate resolution (R = 1000 - 4000) spectrographs which cover the entire lambda = 2.5-20 micron spectral region. Use of large format (1024 x 1024 pixel or larger) IR detector arrays will allow each spectrograph to cover an entire octave of spectral range per exposure without any moving parts. The telescope is passively cooled by a sun shade to below 65 K, and the detectors are cooled with solid H2 cryogen to approximately 8 K. ABE will be placed in an Earth-trailing one AU solar orbit by a Delta II launch vehicle. This energetically favorable orbit provides a low thermal background, affords good access to the entire sky over the one year mission lifetime, and allows adequate communications bandwidth. The spacecraft will be stabilized in three axes and will be pointed to an accuracy of approximately one arcsecond at ABE's several thousand individual scientific targets.

    The results of a set of laboratory impact experiments (speeds in the range 1-5 km s-1) are reviewed. They are discussed in the context of terrestrial impact ejecta impacting the Moon and hence lunar astrobiology through using the Moon to learn about the history of life on Earth. A review of recent results indicates that survival of quite complex organic molecules can be expected in terrestrial meteorites impacting the lunar surface, but they may have undergone selective thermal processing both during ejection from the Earth and during lunar impact. Depending on the conditions of the lunar impact (speed, angle of impact etc.) the shock pressures generated can cause significant but not complete sterilisation of any microbial load on a meteorite (e.g. at a few GPa 1-0.1% of the microbial load can survive, but at 20 GPa this falls to typically 0.01-0.001%). For more sophisticated biological products such as seeds (trapped in rocks) the lunar impact speeds generate shock pressures that disrupt the seeds (experiments show this occurs at approximately 1 GPa or semi-equivalently 1 km s-1). Overall, the delivery of terrestrial material of astrobiological interest to the Moon is supported by these experiments, although its long term survival on the Moon is a separate issue not discussed here.

    The Astrobiology Explorer (ABE) is a MIDEX mission concept under study at NASA's Ames Research Center in collaboration with Ball Aerospace & Technologies, Corp. ABE will conduct IR spectroscopic observations to address important problems in astrobiology, astrochemistry, and astrophysics. The core observational program would make fundamental scientific progress in understanding the distribution, identity, and evolution of ices and organic matter in dense molecular clouds, young forming stellar systems, stellar outflows, the general diffuse ISM, HII regions, Solar System bodies, and external galaxies. The ABE instrument concept includes a 0.6 m aperture Cassegrain telescope and two moderate resolution (R = 2000-3000) spectrographs covering the 2.5-16 micron spectral region. Large format (1024x 1024 pixel or larger) IR detector arrays and bandpass filters will allow each spectrograph to cover an entire octave of spectral range or more per exposure without any moving parts. The telescope will be cooled below 50K by a cryogenic dewar shielded by a sunshade. The detectors will be cooled to approximately 8K. The optimum orbital configuration for achieving the scientific objectives of the ABE mission is a low background, 1 AU Earth driftaway orbit requiring a Delta II launch vehicle. This configuration provides a low thermal background and allows adequate communications bandwidth and good access to the entire sky over the approximate 1-2 year mission lifetime.

  9. Research planning for subglacial lakes: Lessons learned from Astrobiology and planetary protection

    2003-04-01

    Subglacial lake systems offer the potential of discovering important information about evolutionary processes and unusual life forms, while also representing physical and biological analogues for other icy worlds in our solar system. Because of legitimate environmental concerns and legal constraints, there is a need to plan research on these systems in a manner that minimizes harmful cross contamination while maximizing scientific returns. Scientists involved in space missions to other planets and solar system bodies have faced similar concerns and constraints for decades, and routinely integrate planetary protection considerations into mission planning and design. By comparing and contrasting the planetary protection and environmental issues for astrobiology and polar research, it is possible to identify lessons learned that may be helpful in long range research planning for subglacial lakes. As the science community continues its multi-pronged, multidisciplinary efforts to study subglacial lakes, it can borrow more than just relevant science and technology from other fields. It is also important to acknowledge that public perceptions, beliefs, and concerns can become complications or impediments for proposed research. Ultimately, overall success in studying subglacial lake systems may well depend on understanding how to balance technical and scientific needs with legitimate legal, environmental and societal concerns associated with research activities.

  12. Finding Near-Earth Asteroid (NEA) Destinations for Human Exploration: Implications for Astrobiology

    The current number of known potential NEA targets for HSF is limited to those objects whose orbital characteristics are similar to that of the Earth. This is due to the projected capabilities of the exploration systems currently under consideration and development at NASA. However, NEAs with such orbital characteristics often have viewing geometries that place them at low solar elongations and thus are difficult to detect from the vicinity of Earth. While ongoing ground-based surveys and data archives maintained by the NEO Program Observation Program Office and the Minor Planet Center (MPC) have provided a solid basis upon which to build, a more complete catalog of the NEO population is required to inform a robust and sustainable HSF exploration program. Since all the present NEO observing assets are currently confined to the vicinity of the Earth, additional effort must be made to provide capabilities for detection of additional HSF targets via assets beyond Earth orbit. A space-based NEO survey telescope located beyond the vicinity of the Earth, has considerable implications for planetary science and astrobiology. Such a telescope will provide foundational knowledge of our Solar System small body population and detect targets of interest for both the HSF and scientific communities. Data from this asset will yield basic characterization data on the NEOs observed (i.e., albedo, size determination, potential for volatiles and organics, etc.) and help down select targets for future HSF missions. Ideally, the most attractive targets from both HSF and astrobiology perspectives are those NEAs that may contain organic and volatile materials, and which could be effectively sampled at a variety of locations and depths. Presented here is an overview of four space-based survey concepts; any one of which after just a few years of operation will discover many highly accessible NEO targets suitable for robotic and human exploration. Such a space-based survey mission will reveal

  15. Astrobiological Phase Transition: Towards Resolution of Fermi's Paradox

    NASA Astrophysics Data System (ADS)

    Ćirković, Milan M.; Vukotić, Branislav

    2008-12-01

    Can astrophysics explain Fermi’s paradox or the “Great Silence” problem? If available, such explanation would be advantageous over most of those suggested in literature which rely on unverifiable cultural and/or sociological assumptions. We suggest, instead, a general astrobiological paradigm which might offer a physical and empirically testable paradox resolution. Based on the idea of James Annis, we develop a model of an astrobiological phase transition of the Milky Way, based on the concept of the global regulation mechanism(s). The dominant regulation mechanisms, arguably, are γ-ray bursts, whose properties and cosmological evolution are becoming well-understood. Secular evolution of regulation mechanisms leads to the brief epoch of phase transition: from an essentially dead place, with pockets of low-complexity life restricted to planetary surfaces, it will, on a short (Fermi-Hart) timescale, become filled with high-complexity life. An observation selection effect explains why we are not, in spite of the very small prior probability, to be surprised at being located in that brief phase of disequilibrium. In addition, we show that, although the phase-transition model may explain the “Great Silence”, it is not supportive of the “contact pessimist” position. To the contrary, the phase-transition model offers a rational motivation for continuation and extension of our present-day Search for ExtraTerrestrial Intelligence (SETI) endeavours. Some of the unequivocal and testable predictions of our model include the decrease of extinction risk in the history of terrestrial life, the absence of any traces of Galactic societies significantly older than human society, complete lack of any extragalactic intelligent signals or phenomena, and the presence of ubiquitous low-complexity life in the Milky Way.

    Rugged shorelines, laced with canyons, leading to ethane/methane seas glimpsed through an organic haze, vast fields of dunes shaped by alien sciroccos… An icy moon festooned with plumes of water-ice and organics, whose warm watery source might be glimpsed through surface cracks that glow in the infrared… The revelations by Cassini-Huygens about Saturn's crown jewels, Titan and Enceladus, have rocked the public with glimpses of new worlds unimagined a decade before. The time is at hand to capitalize on those discoveries with a broad mission of exploration that combines the widest range of planetary science disciplines—Geology, Geophysics, Atmospheres, Astrobiology,Chemistry, Magnetospheres—in a single NASA/ESA collaboration. The Titan Saturn System Mission will explore these exciting new environments, flying through Enceladus' plumes and plunging deep into Titan's atmosphere with instruments tuned to find what Cassini could only hint at. Exploring Titan with an international fleet of vehicles; from orbit, from the surface of a great polar sea, and from the air with the first hot air balloon to ride an extraterrestrial breeze, TSSM will turn our snapshot gaze of these worlds into an epic film. This paper will describe a collaborative NASA-ESA Titan Saturn System Mission that will open a new phase of planetary exploration by projecting robotic presence on the land, on the sea, and in the air of an active, organic-rich world.

    2014-01-01

    Abstract Data management and sharing are growing concerns for scientists and funding organizations throughout the world. Funding organizations are implementing requirements for data management plans, while scientists are establishing new infrastructures for data sharing. One of the difficulties is sharing data among a diverse set of research disciplines. Astrobiology is a unique community of researchers, containing over 110 different disciplines. The current study reports the results of a survey of data management practices among scientists involved in the astrobiology community and the NASA Astrobiology Institute (NAI) in particular. The survey was administered over a 2-month period in the first half of 2013. Fifteen percent of the NAI community responded (n=114), and additional (n=80) responses were collected from members of an astrobiology Listserv. The results of the survey show that the astrobiology community shares many of the same concerns for data sharing as other groups. The benefits of data sharing are acknowledged by many respondents, but barriers to data sharing remain, including lack of acknowledgement, citation, time, and institutional rewards. Overcoming technical, institutional, and social barriers to data sharing will be a challenge into the future. Key Words: Data management—Data sharing—Data preservation. Astrobiology 14, 451–461.

    While astrobiology is apparently growing steadily around the world, in terms of the number of researchers drawn into this interdisciplinary area and teaching courses provided for new students, there have been very few studies conducted to chart this expansion quantitatively. To address this deficiency, the Astrobiology Society of Britain (ASB) conducted a questionnaire survey of universities and research institutions nationwide to ascertain the current extent of astrobiology research and teaching in the UK. The aim was to provide compiled statistics and an information resource for those who seek research groups or courses of study, and to facilitate new interdisciplinary collaborations. The report here summarizes details gathered on 33 UK research groups, which involved 286 researchers (from undergraduate project students to faculty members). The survey indicates that around 880 students are taking university-level courses, with significant elements of astrobiology included, every year in the UK. Data are also presented on the composition of astrobiology students by their original academic field, which show a significant dominance of physics and astronomy students. This survey represents the first published systematic national assessment of astrobiological academic activity and indicates that this emerging field has already achieved a strong degree of penetration into the UK academic community.

    Conference logo The 21st century has been called the century of environmental revolution. Green innovations and environmentally friendly production systems based on physics, chemistry, materials science, and electronic engineering will be indispensable for ensuring renewable energy and establishing a sustainable society. In particular, production design, materials processing, and fabrication technologies such as welding and joining will be very important components of such green innovations. For these reasons, the International Symposium on Materials Science and Innovation for Sustainable Society - eco-materials and eco-innovation for global sustainability - (ECO-MATES 2011) was organized by the Joining and Welding Research Institute (JWRI) and the Center of Environmental Innovation Design for Sustainability (CEIDS), Osaka University. ECO-MATES 2011 was held at Hotel Hankyu Expo Park, Osaka, Japan from 28-30 November 2011. 435 participants from 20 countries around the world attended the symposium. 149 oral presentations including 60 invited talks and 160 posters were presented at the symposium to discuss the latest research and developments in green innovations in relation to environmental issues. The topics of the symposium covered all environmentally related fields including renewable energy, energy-materials, environment and resources, waste and biomass, power electronics, semiconductor, rare-earth metals, functional materials, organic electronics materials, electronics packaging, smart processing, joining and welding, eco-efficient processes, and green applied physics and chemistry. Therefore, 55 full papers concerning green innovations and environmentally benign production were selected and approved by the editorial board and the program committee of ECO-MATES 2011. All papers were accepted through peer review processes. I believe that all the papers have many informative contents. On behalf of the steering committee of the symposium, I would like to express

    Two recent studies have uncovered corroborating spectral evidence for talc in Nili Fossae on Mars using the CRISM spectrometer on Mars Reconnaissance Orbiter. Inspired by fieldwork in the Pilbara region of Western Australia, Brown et al. (2010) suggested talc was present in some locations where saponite had been identified in the earlier study by Ehlmann et al. (2009). Viviano et al. (2013) then found an identifying marker for talc vs. saponite which confirmed the presence of talc and mapped the locations of the mineral signature using this spectral feature . Talc is an important mineral for identifying processes of hydrothermal alteration in ultramafic sequences in the Archean greenstone belts on Earth. As an alteration mineral of Mg-olivine it is likely to play the same role on Mars, where cumulate overturn has been suggested to have left a highly magnesian upper mantle (Elkins-Tanton et al. 2005). Early Mars and Earth had hotter mantles in their early stages of formation, following overturn of their respective magma oceans, when life began on Earth and may have started on Mars (Russell et al. 2014). In this presentation, we will show how talc (particularly in combination with carbonate) is an important indicator mineral for identifying the hydrothermal alteration of ultramafic sequences, and as such may lead the way to astrobiologically critical regions on Mars and specifically in Nili Fossae.

  11. Students' Socio-Scientific Reasoning in an Astrobiological Context During Work with a Digital Learning Environment

    In a European project—CoReflect—researchers in seven countries are developing, implementing and evaluating teaching sequences using a web-based platform (STOCHASMOS). The interactive web-based inquiry materials support collaborative and reflective work. The learning environments will be iteratively tested and refined, during different phases of the project. All learning environments are focusing "socio-scientific issues". In this article we report from the pilot implementation of the Swedish learning environment which has an Astrobiology context. The socio-scientific driving questions are "Should we look for, and try to contact, extraterrestrial life?", and "Should we transform Mars into a planet where humans can live in the future?" The students were in their last year of compulsory school (16 years old), and worked together in triads. We report from the groups' decisions and the support used for their claims. On a group level a majority of the student groups in their final statements express reluctance towards both the search of extraterrestrial life and the terraforming of Mars. The support used by the students are reported and discussed. We also look more closely into the argumentation of one of the student groups. The results presented in this article, differ from earlier studies on students' argumentation and decision making on socio-scientific issues (Aikenhead in Science education for everyday life. Evidence-based practice. Teachers College Press, New York, (2006) for an overview), in that they suggest that students do use science related arguments—both from "core" and "frontier" science—in their argumentation and decision making.

    Marshall, John R.

    2002-01-01

    This publication list is submitted as a summary of the work conducted under Cooperative Agreement 1120. The goal of the 1120 research was to study granular materials within a planetary, astrophysical, and astrobiological context. This involved research on the physical, mechanical and electrostatic properties of granular systems, as well as the examination of these materials with atomic force microscopy and x-ray analysis. Instruments for analyzing said materials in planetary environments were developed, including the MECA (Mars Environment Compatibility Assessment) experiment for the MSP '01 lander, the ECHOS/MATADOR experiment for the MSP '03 lander, an ISRU experiment for the '03 lander, and MiniLEAP technology. Flight experiments for microgravity (Space Station and Shuttle) have also been developed for the study of granular materials. As expressed in the publications, work on 1120 encompassed laboratory research, theoretical modeling, field experiments, and flight experiments: a series of successful new models were developed for understanding the behavior of triboelectrostatically charged granular masses, and 4 separate instruments were selected for space flight. No inventions or patents were generated by the research under this Agreement.

    A central focus of astrobiology is the determination of abiotic formation routes to important biomolecules. The dissociation mechanisms of these molecules lend valuable insights into their synthesis pathways. Because of the detection of organic anions in the interstellar medium (ISM), it is imperative to study their role in these syntheses. This work aims to experimentally and computationally examine deprotonated adenine and guanine dissociation in an effort to illuminate potential anionic precursors to purine formation. Collision-induced dissociation (CID) products and their branching fractions are experimentally measured using an ion trap mass spectrometer. Deprotonated guanine dissociates primarily by deammoniation (97%) with minor losses of carbodiimide (HNCNH) and/or cyanamide (NH2CN), and isocyanic acid (HNCO). Deprotonated adenine fragments by loss of hydrogen cyanide and/or isocyanide (HCN/HNC; 90%) and carbodiimide (HNCNH) and/or cyanamide (NH2CN; 10%). Tandem mass spectrometry (MS(n)) experiments reveal that deprotonated guanine fragments lose additional HCN and CO, while deprotonated adenine fragments successively lose HNC and HCN. Every neutral fragment observed in this study has been detected in the ISM, highlighting the potential for nucleobases such as these to form in such environments. Lastly, the acidity of abundant fragment ions is experimentally bracketed. Theoretical calculations at the B3LYP/6-311++G(d,p) level of theory are performed to delineate the mechanisms of dissociation and analyze the energies of reactants, intermediates, transition states, and products of these CID processes.

  19. Astrobiology, space and the future age of discovery.

    Astrobiology is the study of the origins, evolution, distribution and future of life in the Universe, and specifically seeks to understand the origin of life and to test the hypothesis that life exists elsewhere than on Earth. There is a general mathematics, physics and chemistry; that is, scientific laws that obtain on Earth also do so elsewhere. Is there a general biology? Is the Universe life-rich or is Earth an isolated island of biology? Exploration in the Age of Enlightenment required the collection of data in unexplored regions and the use of induction and empiricism to derive models and natural laws. The current search for extra-terrestrial life has a similar goal, but with a much greater amount of data and with computers to help with management, correlations, pattern recognition and analysis. There are 60 active space missions, many of them aiding in the search for life. There is not a universally accepted definition of life, but there are a series of characteristics that can aid in the identification of life elsewhere. The study of locations on Earth with similarities to early Mars and other space objects could provide a model that can be used in the search for extra-terrestrial life. PMID:21220277

    Great strides have been made in our understanding of interstellar material thanks to advances in infrared astronomy and laboratory astrophysics. Ionized polycyclic aromatic hydrocarbons (PAHs), shockingly large molecules by earlier astrochemical standards, are widespread and very abundant throughout much of the cosmos. In cold molecular clouds, the birthplace of planets and stars, interstellar atoms and molecules freeze onto extremely cold dust and ice particles forming mixed molecular ices dominated by simple species such as water, methanol, ammonia, and carbon monoxide. Within these clouds, and especially in the vicinity of star and planet forming regions, these ices and PAHs are processed by ultraviolet light and cosmic rays forming hundreds of far more complex species, some of biogenic interest. Eventually, these are delivered to primordial planets by comets and meteorites. As these materials are the building blocks of comets and related to carbonaceous micrometeorites, they are likely to be important sources of complex organic materials delivered to habitable planets (including the primordial Earth) and their composition may be related to the origin of life. This talk will focus on the chemical evolution of these cosmic materials and their relevance to astrobiology.
