    Space ecoliteracy is a historical necessity and vital aspect of space age.Space Situational Awareness has taught lessons for mankind to look inward while stretching beyond cradle in human endeavours. Quality of life for every one on the only home of mankind-TERRA shall be a feasibility only after realizing Space ecoliteracy amongst all stakeholders in space quest. Objectives of Informal Environmental Education(UNESCO/UNEP/IEEP,1977) mandates awareness, attitude, knowledge, skill and participation at Individual and Community domains. Application of Space Technology at both Telecommunications and Remote Sensing domain have started making the fact that mankind has a challenge to learn and affirm earthmanship. Community empowerment focus after Earth Summit 1992 mandate of Sustainable Development has demonstrated a deluge of best practices in Agriculture,Urban, Industries and service sectors all over the globe. Further, deployment of Space technologies have proved the immense potential only after pre-empting the participatory approach at individual and community levels.Indian Space Programme with its 44th year of space service to national development has demonstrated self reliance in space technology for human development. Space technology for the most underdeveloped is a success story both in communication and information tools for quality of life. In this presentation Five Space Ecoliteracy models designed and validated since 1985 till date on informal environmental education namely 1) Ecological Environmental Studies by Students-EESS (1988): cited as one of the 20 best eco -education models by Earth Day Network,2)Community Eco Literacy Campaign-CEL,(2000): cited as a partner under Clean Up the World Campaign,UN, 3) Space Eco Literacy(2011)-an informa 8 week space eco literacy training reported at 39th COSPAR 12 assembly and 4) Space Eco Literacy by Practice(2014)- interface with formal education at institutions and 5) Space Ecoliteracy Mission as a space out reach in

  4. Space education

    NASA Astrophysics Data System (ADS)

    Abiodun, Adigun Ade

    An essential pre-requisite to a successful space technology applications programme is the building of various indigenous capacities, particularly human resources. Efforts to accomplish such a capacity-building must be devoted, at the local level, to the development of necessary high-level knowledge and expertise in space science and technology fields. Such a programme must also focus on long-term in-depth education and research opportunities in the developing countries, where the beneficiaries would gain an in-depth understanding and appreciation of not only the application potentials of a given technology but also an insight into why and how the technology works the way it does. In recognition of such a pre-requisite, it is universally acknowledged that if effective assimilation of space science and appropriate application of space technology are to succeed in the developing countries, and particularly if such a discipline as satellite remote sensing is to transcend its current image of being a technology-driven tool into a user-driven one, efforts must be devoted, at the local level, to the development of necessary high-level knowledge and expertise in requisite space science and technology fields. The justification for such an in-depth education is not far-fetched particularly as one reflects on the myriad of space science and technology activities that are both in progress and are planned. Aspects of these are reflected in this paper.

    Enhancing space weather education is important to space science endeavors. While participating in the Space Weather Research, Education and Development Initiative (SW REDI) Bootcamp and working as a Space Weather Analyst Intern, several innovative technologies and tools were integral to my learning and understanding of space weather analysis and forecasting. Two of the tools utilized in learning about space weather were the Integrated Space Weather Analysis System (iSWA) and the Space Weather Database Of Notifications, Knowledge, Information (DONKI). iSWA, a web-based dissemination system, hosts many state-of-the-art space weather models as well as real time space weather data from spacecraft such as Solar Dynamics Observatory and the Advanced Composition Explorer. As a customizable tool that operates in real-time while providing access also to historical data, iSWA proved essential in my understanding the drivers and impacts of space weather. DONKI was instrumental in accessing historical space weather events to understand the connections between solar phenomena and their effects on Earth environments. DONKI operates as a database of space weather events including linkages between causes and effects of space weather events. iSWA and DONKI are tools available also to the public. They not only enrich the space weather learning process but also allow researchers and model developers access to essential heliophysics and magnetospheric data.

  10. Using Asteroid Scale Models in Space Science Education for Blind and Visually Impaired Students

    NASA Astrophysics Data System (ADS)

    Beck-Winchatz, Bernhard; Ostro, Steven J.

    A major obstacle confronting blind and visually impaired students in their science education is the inaccessibility to graphical materials that are critically instructive and abundantly available to sighted students. The use of three-dimensional models can effectively address this problem. Specifically, this article discusses how scale models of near-Earth asteroids can be used to teach space science to blind and visually impaired students. The models, published in the peer-reviewed literature and in almost every case based on radar observations, are developed with a rapid prototyping process. With these models, many of the recent exciting discoveries about near-Earth asteroids suddenly are directly accessible to blind and visually impaired people. Recent research has shown that many sighted students also learn better when their haptic sense is engaged.

    2008-12-01

    An elementary science education professional development partnership between Culver City Unified School District teachers and UCLA has been formed. The project was designed to assist teachers to comfortably present introductory space science concepts, to support them in their efforts, and to aid them in encouraging their students to develop inquiry skills related to space sciences. The project encourages teacher use of observational science techniques in their classrooms, the use of NASA solar mission images and enhanced use of astronomical observation to facilitate discovery learning. The integrated approach of the project has fostered collegial learning activities among the participating teachers and offered them opportunities for continued renewal and professional development of teacher competencies in astronomy and space science. The activities used in the classroom were developed by others, classroom tested, and specifically address National Science Education and California Science Content Standards. These activities have been sustained through on-going collaboration between the scientist and the teachers, a summer Research Experience for Teachers program, and on-going, grade-specific, district-sponsored workshops. Assessment of the value of the program is done by the school district and is used to continuously improve each workshop and program component. Culver City (California) Unified School District is a small urban school district located on the Westside of Los Angeles. This paper describes the program and the plans for incorporating IHY-themed science into the classroom.

  20. Space Science and Interdisciplinary Education

    NASA Astrophysics Data System (ADS)

    Foing, B. H.

    The contribution of space science to an education cursus can be conceived as a series of educational modules (each including text books for teacher and pupil, exercises, CD-roms, observations or study projects, kits for hands-on projects, and Internet products from space agencies) covering different age groups (elementary 7-10, middle 10-14, high school 15-17). These modules should not be limited to the science teacher area, but must pervade in all topics of education the same way as space is part of everyday life. Space agencies can contribute to this by supporting a pilot group of teachers on sabbatical residence to develop these modules. These teachers should cover different European languages (e.g. English, French, German, other languages), different educational systems experience, and different backgrounds (Language/arts, science, history, technology). These modules could be developed in one year, in partnership with education ministers, publishers, for validation and production. They should be distributed and inserted in curricula via education authorities and networks of teachers. We list some examples of space (science) modules to be developed, in different teachers courses for a total of about 20 hours courses/yr, with basic modules for age group (7-10 yr) and Advanced Modules for (10-15 yr).

  5. Operational Space Weather in USAF Education

    NASA Astrophysics Data System (ADS)

    Smithtro, C.; Quigley, S.

    2006-12-01

    Most education programs offering space weather courses are understandably and traditionally heavily weighted with theoretical space physics that is the basis for most of what is researched and modeled. While understanding the theory is a good and necessary grounding for anyone working the field of space weather, few military or commercial jobs employ such theory in real-time operations. The operations sites/centers are much more geared toward use of applied theory-resultant models, tools and products. To ensure its operations centers personnel, commanders, real-time system operators and other customers affected by the space environment are educated on available and soon-to-be operational space weather models and products, the USAF has developed applicable course/lecture material taught at various institutions to include the Air Force Institute of Technology (AFIT) and the Joint Weather Training Complex (335th/TRS/OUA). Less frequent training of operational space weather is available via other venues that will be discussed, and associated course material is also being developed for potential use at the National Security Space Institute (NSSI). This presentation provides an overview of the programs, locations, courses and material developed and/or taught by or for USAF personnel dealing with operational space weather. It also provides general information on student research project results that may be used in operational support, along with observations regarding logistical and professional benefits of teaching such non-theoretical/non-traditional material.

  8. Four educational programs in Space Life Sciences.

    PubMed

    Luttges, M W; Stodieck, L S; Klaus, D M

    1994-01-01

    Four different educational programs impacting Space Life Sciences are described: the NASA/USRA Advanced Design Program, the NASA Specialized Center of Research and Training (NSCORT) Program, the Centers for the Commercial Development of Space (CCDS) Program, and the NASA Graduate Research Fellow Program. Each program makes somewhat different demands on the students engaged in them. Each program, at the University of Colorado, involves Space Life Sciences training. While the Graduate Student Research Fellow and NSCORT Programs are discipline oriented, the Advanced Design and CCDS Programs are focused on design, technologies and applications. Clearly, the "training paradigms" differ for these educational endeavors. But, these paradigms can be made to mutually facilitate enthusiasm and motivation. Discipline-oriented academic programs, ideally, must be flexible enough to accommodate the emergent cross-disciplinary needs of Space Life Sciences students. Models for such flexibility and resultant student performance levels are discussed based upon actual academic and professional records. PMID:11537954

  9. Educational use of 3D models and photogrammetry content: the Europeana space project for Cypriot UNESCO monuments

    NASA Astrophysics Data System (ADS)

    Ioannides, M.; Chatzigrigoriou, P.; Bokolas, V.; Nikolakopoulou, V.; Athanasiou, V.

    2016-08-01

    Digital heritage data are now more accessible through crowdsourcing platforms, social media and blogs. At the same time, evolving technology on 3D modelling, laser scanning and 3D reconstruction is constantly upgrading and multiplying the information that we can use from heritage digitalisation. The question of reusing the information in different aspects rises. Educators and students are potential users of the digital content; developing for them an adaptable environment for applications and services is our challenge. One of the main objective of the EU Europeana Space project is the development of a holistic approach for educating people (grown ups and kids) on Monuments that are listed at UNESCO world heritage list, in Cyprus. The challenge was the use of Europeana Data (Pictures and the 3D objects) in a way that the information on the platform would be comprehensible by the users. Most of the data have little metadata information and they lack history and cultural value description (semantics). The proposed model ction is based on the cross cultural approach which responds to the multicultural features of present era but at the same time to the contemporary pedagogical and methodological directions. The system uses all innovative digital heritage resources, in order to help the user, in a UX friendly way, to learn about the different phases of the monument, the history, the pathology state, the architectural value and the conservation stage. The result is a responsive platform, accessible through smart devices and desktop computers, (in the frame of "Bring Your Own Device" a.k.a. BYOD) where every Monument is a different course and every course is addressed to different age groups (from elementary level to adults' vocational training).

  14. Space habitat contamination model

    NASA Technical Reports Server (NTRS)

    Morgenthaler, George W.

    1990-01-01

    When one considers the missions that are involved in Space Exploration Initiative (SEI), a continuous Lunar Base at which astronauts will perform scientific experiments as well as being the center for Lunar resource exploitation, a human visit to the surface of Mars, and, later, the development of a Mars base, one recognizes that we have entered a new realm of space exploration activity. During the SEI era, human beings who are involved in such missions will be away from Earth for extended periods of time, even for years. For example, the classical Hohmann transfer round trip mission to Mars would involve a flight of 31 months, including the stay time in the vicinity of Mars. Of course, other Mars trips such as the Venus Fly-By mission (22 months) and the Mars Sprint mission (15 months) pose much less taxing problems, but still problems which put human space presence in a domain where human survival has not yet been tested and thoroughly understood. Humans have never before been placed into an isolated, low-gravity, hermetically sealed, contaminant-prone environment for periods well in excess of one year and then been expected to function normally upon return to Earth. This presentation develops a systems model to help analyze the space habitat containment growth problem and to indicate the thresholds of astronaut risk, astronaut operational impairment, and methods of risk mitigation. The model inputs were discussed with toxicology experts at the University of Colorado Health Services Center and the University of Rochester.

  15. Popularizing Space Education in Indian Context

    NASA Astrophysics Data System (ADS)

    Yalagi, Amrut

    Indians have many mythological stories about many constellations and stars. Hindu months are based on MOON and 27 stars on Zodiac. They are very important for many Indians in ritual, religious functions. By prompting them to identify their birth star, really makes them elevated. Similarly conveying them the importance of star gazing with respect to their day today life makes them to take interest and active participation in Space Activities. Space activities should be driven by public; their requirements; their dreams and imaginations. Their active participation definitely gives valuable inputs to space scientists. Hence, there is a need of involving common man or public mass by appropriate motivation by organising sky gazing sessions, exhibitions, workshops, etc. In this connection, even if the some organisation are able to attract a small percent of qualified engineers/scientists,, enthusiastic students, it would result in the creation of a sizable pool of talent in space sciences,which may well determine the future mankind on this planet. Some simple motivation acts have made the people to take interest in space. we have been using certain methodologies to popularize space science - 1] Conducting theory sessions on basics of star gazing and conveying importance of sky gazing with respect to day-today life. 2] Organising seminars, workshops, lectures and other academic/popular science activities with special reference to space science 3] Projects - a] Cubsat Missions b] Automatic Weather Station Facility c] Model making d] Creating and simulating space models and rover making competitions. The 50 year's of Exploration has left tremendous impact on many society's working towards space education and exploration.

    2002-07-01

    Despite a considerable growth in space related industry and scientific research over the past few decades, space related education has largely been neglected in our country. NAROM - the National Centre for Space Related Education - was formed last year to organize space related educational activities, to promote recruitment, to promote appreciation for the benefits of space activities, and to stimulate interest for science in general. This year, nine students from Narvik Engineering College have participated in the Hotel Payload Project (HPP) at Andøya Rocket Range. They have thus played an active and essential role in an ongoing engineering project.

    Russell, R. M.; Johnson, R. M.

    2010-12-01

    Magnetic and electric fields and phenomena play important roles in various situations in astronomy, planetary science, and Earth science. Students often lack an intuitive sense of electromagnetic phenomena, and therefore struggle with the complexities of planetary and stellar magnetic fields. Hands-on magnetism activities can provide students with an intuitive grasp of the basics of magnetism, preparing them for more challenging conceptual studies of magnetic phenomena. For the past six years, we have been presenting a professional development workshop for teachers covering the topics of magnetism and space weather. The workshop, which has been conducted more than 20 times for a range of audiences, blends together several simple hands-on activities, background information on space weather and geomagnetism, a collection of images, animations, and interactives that illustrate important concepts, and guidance about specific links between these topics and national science education standards. These workshops have been very well-received, and have consistently been rated highly by participants in surveys. We believe the methods used in these workshops can be applied to other topics in science education and to astronomy and Earth science education specifically. In this presentation, we will describe our magnetism and space weather workshop, including some of the hands-on activities. We will describe successful aspects of the workshop and comment on ways we think this approach could be replicated for other topics. We will also display some of the interactives, graphics, and animations shown during the workshops. Resources have been added to the workshop over the years in response to recurring questions from teachers; we will comment on this process and how it might be applied to other topics. The activities and extensive background content used or referenced in the workshop are available for free on the Windows to the Universe web site (www.windows2universe.org). Hands on

    Kiruna Space and Environment Campus is a concept, currently under development, to pool together the resources of Luleå University of Technology, Umeå University, and the Swedish Institute of Space Physics on one site of the same name, in the town of Kiruna, with the task to co-ordinate and develop university education and research in space and environmental studies. Kiruna, the northernmost municipality in Sweden with an area equal to about half of Switzerland and a population of about 23 000, has a long tradition in space research and even longer tradition in a number of environmental research topics. Since the 1960s it has here been possible to conduct Ph. D. studies in Space Physics and graduate education is now also given in Atmospheric Physics and Space Technology. The past decade has also seen a great expansion in undergraduate engineering programmes in Kiruna, which have attracted many students including an unusually large number of female students. These programmes are run completely, or partly, in Kiruna by the Umeå University and Luleå University of Technology. They cover a wide spectrum, practically oriented and more theoretical, leading to Bachelor`s and Master`s degrees in Space Engineering and Geographical Information Systems Engineering. Key features are close contact between research and education, hand`s on experiences and international co-operation. At present there are more than 100 full-time students studying on the programmes in Kiruna. One of the goals set by the Government of Sweden for the new Kiruna Space and Environment Campus, is to expand and broaden the existing educational programmes in Kiruna in order to have 450 full-time undergraduate students studying there within a few years. Expansion is planned to take place both in various aspects of space studies, in environmental studies and in studies involving both space and the environment.

    The advancement of space exploration using nuclear science and technology has been a goal sought by many individuals over the years. The quest to enable space nuclear applications has experienced many challenges such as funding restrictions; lack of political, corporate, or public support; and limitations in educational opportunities. The Center for Space Nuclear Research (CSNR) was established at the Idaho National Laboratory (INL) with the mission to address the numerous challenges and opportunities relevant to the promotion of space nuclear research and education.1 The CSNR is operated by the Universities Space Research Association and its activities are overseen by a Science Council comprised of various representatives from academic and professional entities with space nuclear experience. Program participants in the CSNR include academic researchers and students, government representatives, and representatives from industrial and corporate entities. Space nuclear educational opportunities have traditionally been limited to various sponsored research projects through government agencies or industrial partners, and dedicated research centers. Centralized research opportunities are vital to the growth and development of space nuclear advancement. Coordinated and focused research plays a key role in developing the future leaders in the space nuclear field. The CSNR strives to synchronize research efforts and provide means to train and educate students with skills to help them excel as leaders.

    The Philippines has recently started in developing and promoting space science education through the Philippine Space Science Education Program (PSSEP) of the Department of Science and Technology (DOST). However, as a developing country, there are numerous challenges in promoting space education to students and teachers. In this paper, we assessed the recent activities done by the PSSEP and demonstrate their effectiveness. In addition, we will expound on the social, political and logistical challenges of promoting space education in an archipelago such as the Philippines. We will also present the preliminary feedback and assessment of the Space Science Program (SSP), a pilot program which teaches space science as a separate subject in the basic educational system from kindergarten to high school. We will also discuss the various teaching strategies we utilized in the SSP that can be adopted depending on the needs and capabilities of the host school. Finally, we discuss the challenges of instituting a formal astronomy and space science course and the issues that needs to be addressed for an effective and sustainable program.

    Joels, K. M.

    1978-01-01

    The components of an educational system based on, and perhaps enhanced by, space industrialization communications technology are considered. Satellite technology has introduced a synoptic distribution system for various transmittable educational media. The cost of communications satellite distribution for educational programming has been high. It has, therefore, been proposed to utilize Space Shuttle related technology and Large Space Structures (LSS) to construct a system with a quantum advancement in communication capability and a quantum reduction in user cost. LSS for communications purposes have three basic advantages for both developed and emerging nations, including the ability to distribute signals over wide geographic areas, the reduced cost of satellite communications systems versus installation of land based systems, and the ability of a communication satellite system to create instant educational networks.

  19. Space Flight Cable Model Development

    NASA Technical Reports Server (NTRS)

    Spak, Kaitlin

    2013-01-01

    This work concentrates the modeling efforts presented in last year's VSGC conference paper, "Model Development for Cable-Harnessed Beams." The focus is narrowed to modeling of space-flight cables only, as a reliable damped cable model is not yet readily available and is necessary to continue modeling cable-harnessed space structures. New experimental data is presented, eliminating the low-frequency noise that plagued the first year's efforts. The distributed transfer function method is applied to a single section of space flight cable for Euler-Bernoulli and shear beams. The work presented here will be developed into a damped cable model that can be incorporated into an interconnected beam-cable system. The overall goal of this work is to accurately predict natural frequencies and modal damping ratios for cabled space structures.

    Space exploration and observations from space offer unique opportunities with respect to education. Recent technical advances have significantly increased the width and sensitivity of the electromagnetic spectrum window through which we are able to 'see' the universe. Observations from space have forced a realization that the earth is a beautiful, complex, and interconnected system. Space astronomy and the remote sensing of objects throughout our solar system have the potential of providing unique educational opportunities. Modern technologies have significantly reduced the cost of collecting, transmitting and processing data. Consequently, we are entering an age where it is possible to open up the process of discovery to almost everyone - and especially to young people throughout the world.

    The Wisconsin Earth and Space Science Education project successfilly met its objectives of creating a comprehensive online portfolio of science education curricular resources and providing a professional development program to increase educator competency with Earth and Space science content and teaching pedagogy. Overall, 97% of participants stated that their experience was either good or excellent. The favorable response of participant reactions to the professional development opportunities highlights the high quality of the professional development opportunity. The enthusiasm generated for using the curricular material in classroom settings was overwhelmingly positive at 92%. This enthusiasm carried over into actual classroom implementation of resources from the curricular portfolio, with 90% using the resources between 1-6 times during the school year. The project has had a positive impact on student learning in Wisconsin. Although direct measurement of student performance is not possible in a project of this kind, nearly 75% of participating teachers stated that they saw an increase in student performance in math and science as a result of using project resources. Additionally, nearly 75% of participants saw an increase in the enthusiasm of students towards math and science. Finally, some evidence exists that the professional development academies and curricular portfolio have been effective in changing educator behavior. More than half of all participants indicated that they have used more hands-on activities as a result of the Wisconsin Earth and Space Science Education project.

    2002-01-01

    The poster presented will give an overview of a study towards a "Space Road Show". The topic of this show is space science. The target group is adolescents, aged 12 to 15, at Dutch high schools. The show and its accompanying experiments would be supported with suitable educational material. Science teachers at schools can decide for themselves if they want to use this material in advance, afterwards or not at all. The aims of this outreach effort are: to motivate students for space science and engineering, to help them understand the importance of (space) research, to give them a positive feeling about the possibilities offered by space and in the process give them useful knowledge on space basics. The show revolves around three main themes: applications, science and society. First the students will get some historical background on the importance of space/astronomy to civilization. Secondly they will learn more about novel uses of space. On the one hand they will learn of "Views on Earth" involving technologies like Remote Sensing (or Spying), Communication, Broadcasting, GPS and Telemedicine. On the other hand they will experience "Views on Space" illustrated by past, present and future space research missions, like the space exploration missions (Cassini/Huygens, Mars Express and Rosetta) and the astronomy missions (Soho and XMM). Meanwhile, the students will learn more about the technology of launchers and satellites needed to accomplish these space missions. Throughout the show and especially towards the end attention will be paid to the third theme "Why go to space"? Other reasons for people to get into space will be explored. An important question in this is the commercial (manned) exploration of space. Thus, the questions of benefit of space to society are integrated in the entire show. It raises some fundamental questions about the effects of space travel on our environment, poverty and other moral issues. The show attempts to connect scientific with

  8. Designing learning spaces for interprofessional education in the anatomical sciences.

    PubMed

    Cleveland, Benjamin; Kvan, Thomas

    2015-01-01

    This article explores connections between interprofessional education (IPE) models and the design of learning spaces for undergraduate and graduate education in the anatomical sciences and other professional preparation. The authors argue that for IPE models to be successful and sustained they must be embodied in the environment in which interprofessional learning occurs. To elaborate these arguments, two exemplar tertiary education facilities are discussed: the Charles Perkins Centre at the University of Sydney for science education and research, and Victoria University's Interprofessional Clinic in Wyndham for undergraduate IPE in health care. Backed by well-conceived curriculum and pedagogical models, the architectures of these facilities embody the educational visions, methods, and practices they were designed to support. Subsequently, the article discusses the spatial implications of curriculum and pedagogical change in the teaching of the anatomical sciences and explores how architecture might further the development of IPE models in the field. In conclusion, it is argued that learning spaces should be designed and developed (socially) with the expressed intention of supporting collaborative IPE models in health education settings, including those in the anatomical sciences.

    The success in deployment of the space programs now in many respects depends on comprehension by the citizens of necessity of programs, from "space" erudition of country. Purposefulness and efficiency of the "space" teaching and educational activity depend on knowledge of relationships between separate variables of such process. The empirical methods of ``space'' well-information of the taxpayers should be supplemented by theoretical models permitting to demonstrate a ways of control by these processes. Authors on the basis of their experience of educational activity during 50- years of among the students of space-rocket profession obtain an equation of ``space" state of the society determining a degree of its knowledge about Space, about achievements in its development, about indispensable lines of investigations, rates of informatization of the population. It is supposed, that the change of the space information consists of two parts: (1) - from going of the information about practical achievements, about development special knowledge requiring of independent financing, and (2) from intensity of dissemination of the ``free" information of a general educational line going to the population through mass-media, book, in family, in educational institutions, as a part of obligatory knowledge of any man, etc. In proposed model the level space well-information of the population depends on intensity of dissemination in the society of the space information, and also from a volume of financing of space-rocket technology, from a part of population of the employment in the space-rocket programs, from a factor of education of the population in adherence to space problems, from welfare and mentality of the people, from a rate of unemployment and material inequality. Obtained in the report on these principles the equation of a space state of the society corresponds to catastrophe such as cusp, the analysis has shown which one ways of control of the public understanding of space

    At present, Canada does not have enough scientists to be competitive in the global economy, which is rapidly changing from a reliance on natural resources and industry to information and technology. Space is the final frontier and it is a multidisciplinary endeavor. It requires a knowledge of science and math, as well as non-science areas such as architecture and law. Thus, it can attract a large number of students with a diverse range of interests and career goals. An overview is presented of the space education program designed by Canadian Alumni of the International Space University (CAISU) to encourage students to pursue studies and careers in science and technology and to improve science literacy in Canada.

  14. Space debris modeling at NASA

    NASA Astrophysics Data System (ADS)

    Johnson, Nicholas L.

    2001-10-01

    Since the Second European Conference on Space Debris in 1997, the Orbital Debris Program Office at the NASA Johnson Space Center has undertaken a major effort to update and improve the principal software tools employed to model the space debris environment and to evaluate mission risks. NASA's orbital debris engineering model, ORDEM, represents the current and near-term Earth orbital debris population from the largest spacecraft to the smallest debris in a manner which permits spacecraft engineers and experimenters to estimate the frequency and velocity with which a satellite may be struck by debris of different sizes. Using expanded databases and a new program design, ORDEM2000 provides a more accurate environment definition combined with a much broader array of output products in comparison with its predecessor, ORDEM96. Studies of the potential long-term space debris environment are now conducted with EVOVLE 4.0, which incorporates significant advances in debris characterization and breakup modeling. An adjunct to EVOLVE 4.0, GEO EVOLVE has been created to examine debris issues near the geosynchronous orbital regime. In support of NASA Safety Standard (NSS) 1740.14, which establishes debris mitigation guidelines for all NASA space programs, a set of evaluation tools called the Debris Assessment Software (DAS) is specifically designed for program offices to determine whether they are in compliance with NASA debris mitigation guidelines. DAS 1.5 has recently been completed with improved WINDOWS compatibility and graphics functions. DAS 2.0 will incorporate guideline changes in a forthcoming revision to NSS 1740.14. Whereas DAS contains a simplified model to calculate possible risks associated with satellite reentries, NASA's higher fidelity Object Reentry Survival Analysis Tool (ORSAT) has been upgraded to Version 5.0. With the growing awareness of the potential risks posed by uncontrolled satellite reentries to people and property on Earth, the application of

    NASA Technical Reports Server (NTRS)

    1983-01-01

    This is a photograph of a 1/15 scale model of the Hubble Space Telescope (HST). The HST is the product of a partnership between NASA, European Space Agency Contractors, and the international community of astronomers. It is named after Edwin P. Hubble, an American Astronomer who discovered the expanding nature of the universe and was the first to realize the true nature of galaxies. The purpose of the HST, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low-Earth orbit. By placing the telescope in space, astronomers are able to collect data that is free of the Earth's atmosphere. The HST detects objects 25 times fainter than the dimmest objects seen from Earth and provides astronomers with an observable universe 250 times larger than visible from ground-based telescopes, perhaps as far away as 14 billion light-years. The HST views galaxies, stars, planets, comets, possibly other solar systems, and even unusual phenomena such as quasars, with 10 times the clarity of ground-based telescopes. The major elements of the HST are the Optical Telescope Assembly (OTA), the Support System Module (SSM), and the Scientific Instruments (SI). The HST is 42.5-feet (13- meters) long and weighs about 25,000 pounds (11,600 kilograms). The HST was deployed from the Space Shuttle Discovery (STS-31 mission) into Earth orbit in April 1990. The Marshall Space Flight Center had responsibility for design, development, and construction of the HST. The Perkin-Elmer Corporation, in Danbury, Cornecticut, developed the optical system and guidance sensors. The Lockheed Missile and Space Company of Sunnyvale, California produced the protective outer shroud and spacecraft systems, and assembled and tested the finished telescope.

    2013-04-01

    Earth Observation data and remote sensing technologies have been maturing into useful tools that can be utilised by local authorities and businesses to aid in activates such as monitoring climate change trends and managing agricultural land and water uses. The European Earth observation programme Copernicus, previously known as GMES (Global Monitoring for Environment and Security), provides the means to collect and process multi-source EO and environmental data that supports policy developments at the European level. At the regional and local level, the Copernicus programme has been initiated through Regional Contact Office (RCO), which provide knowledge, training, and access to expertise both locally and at a European level through the network of RCOs established across Europe in the DORIS_Net (Downstream Observatory organised by Regions active In Space - Network) project (Grant Agreement No. 262789 Coordination and support action (Coordinating) FP7 SPA.2010.1.1-07 "Fostering downstream activities and links with regions"). In the East Midlands UK RCO, educational and training workshops and modules have been organised to highlight the wider range of tools and application available to businesses and local authorities in the region. Engagement with businesses and LRA highlighted the need to have a tiered system of training to build awareness prior to investigating innovative solutions and space technology uses for societal benefits. In this paper we outline education and training programmes which have been developed at G-STEP (GMES - Science and Technology Education Partnership), University of Leicester, UK to open up the Copernicus programme through the Regional Contact Office to downstream users such as local businesses and LRAs. Innovative methods to introduce the operational uses of Space technologies in real cases through e-learning modules and web-based tools will be described and examples of good practice for educational training in these sectors will be

  4. The Space Laser Business Model

    NASA Technical Reports Server (NTRS)

    2005-01-01

    Creating long-duration, high-powered lasers, for satellites, that can withstand the type of optical misalignment and damage dished out by the unforgiving environment of space, is work that is unique to NASA. It is complicated, specific work, where each step forward is into uncharted territory. In the 1990s, as this technology was first being created, NASA gave free reign to a group of "laser jocks" to develop their own business model and supply the Space Agency with the technology it needed. It was still to be a part of NASA as a division of Goddard Space Flight Center, but would operate independently out of a remote office. The idea for this satellite laboratory was based on the Skunk Works concept at Lockheed Martin Corporation. Formerly known as the Lockheed Corporation, in 1943, the aerospace firm, realizing that the type of advanced research it needed done could not be performed within the confines of a larger company, allowed a group of researchers and engineers to essentially run their own microbusiness without the corporate oversight. The Skunk Works project, in Burbank, California, produced America s first jet fighter, the world s most successful spy plane (U-2), the first 3-times-the-speed-of-sound surveillance aircraft, and the F-117A Nighthawk Stealth Fighter. Boeing followed suit with its Phantom Works, an advanced research and development branch of the company that operates independent of the larger unit and is responsible for a great deal of its most cutting-edge research. NASA s version of this advanced business model was the Space Lidar Technology Center (SLTC), just south of Goddard, in College Park, Maryland. Established in 1998 under a Cooperative Agreement between Goddard and the University of Maryland s A. James Clark School of Engineering, it was a high-tech laser shop where a small group of specialists, never more than 20 employees, worked all hours of the day and night to create the cutting- edge technology the Agency required of them.

    Despite a considerable growth in space related industry and scientific research over the past few decades, space related education has largely been neglected in our country. NAROM - the National Centre for Space Related Education - was formed last year to organize space related educational activities, to promote recruitment, to promote appreciation for the benefits of space activities, and to stimulate interest for science in general. This year, nine students from Narvik Engineering College have participated in the Hotel Payload Project (HPP) at Anøya Rocket Range. They have thus played an active and essential role in an ongoing engineering project.

  13. The Space Place: Adventures in Informal Education - and Lessons Learned

    NASA Astrophysics Data System (ADS)

    Fisher, D.; Leon, N.

    2001-12-01

    Informal education settings provide unique opportunities to convey Earth and space science learning to a variety of audiences. The NASA Space Place suite of outreach products and activities include deliverables to both the formal and the informal education arenas. The question is, how can Earth and space science efforts best create high-quality products and activities for the informal education sector- and how can these products and activities be effectively disseminated to these audiences? This session will describe the approach by a small outreach team for NASA's New Millennium Program (NMP) Space Place effort. The Space Place team's approach has been three-fold: 1) develop a suite of products designed to appeal to (and educate) the informal education audience, 2) disseminate these products through leveraged distribution channels which serve the informal education community, and 3) invite participation by missions beyond those within NMP, but rather NASA-wide - for a richer and broader message, and a greater variety of content The informal education audience served by the Space Place can be found in science centers, museums, planetariums, libraries, community centers, and community organizations. This informal education audience seeks to be entertained as well as to be educated, and this audience often includes multiple generations. Personnel at informal education venues may or may not have a science background, may or may not have significant training in conducting activities, and may, as often as not, be volunteers. As a result of valuable lessons learned, Space Place materials developed for informal education settings attempt to be adaptable for multiple age groups, and easy to administer. Dissemination to the informal education community could be a daunting effort. But another lesson learned by the Space Place team is the value of alliances with national organizations within that community. These alliances make distribution of the Space Place activities and

  16. Target space pseudoduality in supersymmetric sigma models on symmetric spaces

    NASA Astrophysics Data System (ADS)

    Sarisaman, Mustafa

    We discuss the target space pseudoduality in supersymmetric sigma models on symmetric spaces. We first consider the case where sigma models based on real compact connected Lie groups of the same dimensionality and give examples using three dimensional models on target spaces. We show explicit construction of nonlocal conserved currents on the pseudodual manifold. We then switch the Lie group valued pseudoduality equations to Lie algebra valued ones, which leads to an infinite number of pseudoduality equations. We obtain an infinite number of conserved currents on the tangent bundle of the pseudo-dual manifold. Since pseudoduality imposes the condition that sigma models pseudodual to each other are based on symmetric spaces with opposite curvatures (i.e. dual symmetric spaces), we investigate pseudoduality transformation on the symmetric space sigma models in the third chapter. We see that there can be mixing of decomposed spaces with each other, which leads to mixings of the following expressions. We obtain the pseudodual conserved currents which are viewed as the orthonormal frame on the pullback bundle of the tangent space of G˜ which is the Lie group on which the pseudodual model based. Hence we obtain the mixing forms of curvature relations and one loop renormalization group beta function by means of these currents. In chapter four, we generalize the classical construction of pseudoduality transformation to supersymmetric case. We perform this both by component expansion method on manifold M and by orthonormal coframe method on manifold SO( M). The component method produces the result that pseudoduality transformation is not invertible at all points and occurs from all points on one manifold to only one point where riemann normal coordinates valid on the second manifold. Torsion of the sigma model on M must vanish while it is nonvanishing on M˜, and curvatures of the manifolds must be constant and the same because of anticommuting grassmann numbers. We obtain

    The main purpose of the space sciences education program developed in Moscow State University is to incorporate modern space research in the university and high education and popularize basics of space physics. The First Russian University Satellite "Universitetskiy-Tatyana" launched on January 20, 2005 formed a basis for development of a new approach to the space-physics education. The onboard scientific complex, as well as the mission control and information-receiving center, was designed and developed in Moscow State University. The scientific program of the mission includes measurements of space radiation in various energy ranges, and UV luminosity and lightening from the Earth. Educational materials are concentrated to upper high school, junior and senior university levels. There was developed a special computerized hands-on exercises based on the experimental quasi-realtime data obtained from "Universitetskiy-Tatyana" satellite and other internet resources. Students specialized in space physics from several Russian universities are involved in scientific work based on various scientific data. Moscow State University is now extending its space science education program by creation the electronic textbooks on remote sensing, space factors and materials study, satellite design and development, etc. "Space schools" for university teachers and students were held in 2004 - 2007. The main objective of these schools was to attract interest to space research. The mutual idea of these schools was to join forces of Moscow State University scientists, university teachers and students. For modern university world, it is very important to understand what skills future space scientists and space industry employees must be equipped with. The space sciences educational activity of Moscow State University is a non-profit project and is open for all interested parties.

  1. Space Education in Australia: Public Education and Outreach Through Peer Mentoring

    NASA Astrophysics Data System (ADS)

    Clayfield, K. C.; Kenny, S. J.

    2002-01-01

    In Australia, the number of space education programs aimed at secondary and tertiary students has dramatically increased over the last decade. The majority of these programs are organised by young tertiary-educated volunteers with a passion for space; this mode of education is described as `peer mentoring'. Identifying characteristics of peer mentored programs include increased emphasis on the vocational relevance of the educational material presented, and constant updating of course content and mode of delivery. These educational programs and their activities are discussed. Space education in Australia has benefited greatly from the employment of peer mentoring. The ability of the students to relate to the organisers of the space education experience is a vital part of making sure that the experience is circulated out into the general public through families and friends. Peer mentoring also employs an `educate to educate' philosophy, in which graduates of these space education programs are encouraged to become mentors for future programs. To `educate to educate' is to develop `sustainable education', and with a sustainable educational base comes the best chance for developing a sustainable base of highly motivated and educated space pioneers.

    2009-01-01

    Parametric cost models are routinely used to plan missions, compare concepts and justify technology investments. However, great care is required. Some space telescope cost models, such as those based only on mass, lack sufficient detail to support such analysis and may lead to inaccurate conclusions. Similarly, using ground based telescope models which include the dome cost will also lead to inaccurate conclusions. This paper reviews current and historical models. Then, based on data from 22 different NASA space telescopes, this paper tests those models and presents preliminary analysis of single and multi-variable space telescope cost models.

    The Ionospheric Radio Science Laboratory (IRSL) at Institute of Space Science, National Central University in Taiwan has been conducting a program for public outreach educations on space science by giving lectures, organizing camps, touring exhibits, and experiencing hand-on experiments to elementary school, high school, and college students as well as general public since 1991. The program began with a topic of traveling/living in space, and was followed by space environment, space mission, and space weather monitoring, etc. and a series of course module and experiment (i.e. experiencing activity) module was carried out. For past decadal, the course modules have been developed to cover the space environment of the Sun, interplanetary space, and geospace, as well as the space technology of the rocket, satellite, space shuttle (plane), space station, living in space, observing the Earth from space, and weather observation. Each course module highlights the current status and latest new finding as well as discusses 1-3 key/core issues/concepts and equip with 2-3 activity/experiment modules to make students more easily to understand the topics/issues. Meanwhile, scientific camps are given to lead students a better understanding and interesting on space science. Currently, a visualized image projecting system, Dagik Earth, is developed to demonstrate the scientific results on a sphere together with the course modules. This system will dramatically improve the educational skill and increase interests of participators.

    The Philippines has recently started in developing and promoting space science education through the Philippine Space Science Education Program (PSSEP) of the Department of Science and Technology (DOST). However, as a developing country, there are numerous challenges in promoting space education to students and teachers. In this paper, we assessed the recent activities done by the PSSEP and demonstrate their effectiveness. In addition, we will expound on the social, political and logistical challenges of promoting space education in an archipelago such as the Philippines. We will also present the preliminary feedback and assessment of the Space Science Program (SSP), a pilot program which teaches space science as a separate subject in the basic educational system from kindergarten to high school. We will also discuss the various teaching strategies we utilized in the SSP that can be adopted depending on the needs and capabilities of the host school. Finally, we discuss the challenges of instituting a formal astronomy and space science course and the issues that needs to be addressed for an effective and sustainable program and how it can be utilized to develop a space-capable workforce for a future Philippine Space Agency.

As the national User Support and Operation Center (USOC) for the International Space Station, MARS Center is also willing to provide material, such as videos and data, for educational purposes. In order to base our initiative on authoritative precedents, our first step has been a comparative analysis between different space agency education web sites, such as ESA and NASA. As is well known, Internet is a powerful reality, capable of connecting people all over the world and rendering public a huge amount of information. The first problem, then, is to organize this information, in order to use the web as an efficient education tool. That is why studies such as User Modeling (UM), Human Computer Interaction (HCI) and Semantic Web have become more important in Information Technology and Science. Traditional search engines are unable to provide an optimal retrieval of contents really searched for by users. Semantic Web is a valid alternative: according to its theories, web information should be represented using metadata language. Users should be able and enabled to successfully search, obtain and study new information from web. Forging knowledge in an intelligent manner, preventing users from making errors, and making this formidable quantity of information easily available have also been the starting points for HCI methodologies for defining Adaptable Interfaces. Here the information is divided into different sets, on the basis of the intended user profile, in order to prevent users from getting lost. Realized as an adaptable interface, an education web site can help users to effectively retrieve the information necessary for their scopes (teaching for a teacher and learning for a student). For students it's a great advantage to use interfaces designed on the basis of their age and scholastic level. Indeed, an adaptable interface is intended not just for students, but also for teachers

  14. International Space Station: National Laboratory Education Concept Development Report

    NASA Technical Reports Server (NTRS)

    2006-01-01

    The International Space Station (ISS) program has brought together 16 spacefaring nations in an effort to build a permanent base for human explorers in low-Earth orbit, the first stop past Earth in humanity's path into space. The ISS is a remarkably capable spacecraft, by significant margins the largest and most complex space vehicle ever built. Planned for completion in 2010, the ISS will provide a home for laboratories equipped with a wide array of resources to develop and test the technologies needed for future generations of space exploration. The resources of the only permanent base in space clearly have the potential to find application in areas beyond the research required to enable future exploration missions. In response to Congressional direction in the 2005 National Aeronautics and Space Administration (NASA) Authorization Act, NASA has begun to examine the value of these unique capabilities to other national priorities, particularly education. In early 2006, NASA invited education experts from other Federal agencies to participate in a Task Force charged with developing concepts for using the ISS for educational purposes. Senior representatives from the education offices of the Department of Defense, Department of Education, Department of Energy, National Institutes of Health, and National Science Foundation agreed to take part in the Task Force and have graciously contributed their time and energy to produce a plan that lays out a conceptual framework for potential utilization of the ISS for educational activities sponsored by Federal agencies as well as other future users.

    2001-05-01

    The Hubble Space Telescope has conducted a long-standing and vigorous program in education and public outreach. This program uses a variety of methods to reach a broad spectrum of audiences. Education products are developed in a team environment that partners educators, curriculum experts, scientists, and production experts, such as graphic artists, Web designers, programmers, and education evaluators. A popular Web site is maintained, and has been substantially augmented in the past year. The Amazing Space program consists of a suite of online, interactive modules for use in the kindergarten through 12th grade classroom. The program is rooted in the national education standards and benefits from a robust evaluation process. The HST images and data are used to engage students in learning basic science and mathematics concepts. The activity/lessons include extensive, online assistance for educators, so that they can be readily used in the classroom. Hardcopy products such as posters, lithographs, teacher guides, and trading cards are generally tied to online products, to provide multiple entries to the material. We also provide training for teachers in the use of our products, as appropriate. Informal science education is supported by providing services to museums, planetariums, libraries and related institutions. The very popular ViewSpace, a computer-based video service is being used by many informal science facilities. In addition, HST has supported the creation of both permanent and traveling exhibits about HST. The Space Telescope Science Institute operates the Hubble Space Telescope for NASA.

    As the number of spacefaring nations of the world increases, so does the difficulty of competing in a global economy. The development of high technology products and services for space programs, and the economic exploitation of these technologies for national economic growth, requires professionals versed in both technical and commercial aspects of space. Meeting this requirement academically presents two challenges. On the technical side, enrollment in science and engineering is decreasing in some of the spacefaring nations. From the commerce perspective, very few colleges and universities offer specific courses in space business.

  11. The situation of space education in the unified Germany

    NASA Astrophysics Data System (ADS)

    von Muldau, Hans H.

    Because of the unique situation of the unified Germany it is worth discussing the state of the art and the future aspects of space education in this country. Two different social and educational systems of the F.R.G. (Federal Republic of Germany) and the G.D.R. (German Democratic Republic) have to be synchronized. The increase of the population by the unification affected the space science related people. So the majorities change. At the moment the severe unemployment situation in eastern Germany hides this fact. But we have to be prepared for this in years to come. The different relation to the space science programs of the U.S.A. and Russia for the German scientist gives a chance for more international understanding and cooperation. This becomes a subject of educational approach to the international cooperation problem. The start of DARA (the German national space administration) in 1989 accompanied by dramatic concentration of space knowledge in DASA (the cooperation of the German national space industry) in the late eighties, shows that Germany has begun to concentrate its capabilities. On such a background, space education for the majority of the population becomes understandable and desirable. European commercial unification on an open market at the beginning of 1993 helps to concentrate the Germans on their historical part and task in the European market. Therefore, many solutions to establish effective space education becomes visible which were hidden behind walls of emotions and prejudices in the past. So the forecast for space education in Germany for the nineties has never been better. The only remaining problem—funding—has to be solved by unconventional ways, e.g. a foundation by the industry as in other countries.

    The Ionospheric Radio Science Laboratory (IRSL) at Institute of Space Science, National Central University in Taiwan has been conducting a program for public outreach educations on space science by giving lectures, organizing camps, touring exhibits, and experiencing hand-on experiments to elementary school, high school, and college students as well as general public since 1991. The program began with a topic of traveling/living in space, and was followed by space environment, space mission, and space weather monitoring, etc. and a series of course module and experiment (i.e. experiencing activity) module was carried out. For past decadal, the course modules have been developed to cover the space environment of the Sun, interplanetary space, and geospace, as well as the space technology of the rocket, satellite, space shuttle (plane), space station, living in space, observing the Earth from space, and weather observation. Each course module highlights the current status and latest new finding as well as discusses 1-3 key/core issues/concepts and equip with 2-3 activity/experiment modules to make students more easily to understand the topics/issues. Regarding the space technologies, we focus on remote sensing of Earth's surface by FORMOSAT-2 and occultation sounding by FORMOSAT-3/COSMIC of Taiwan space mission. Moreover, scientific camps are given to lead students a better understanding and interesting on space sciences/ technologies. Currently, a visualized image projecting system, Dagik Earth, is developed to demonstrate the scientific results on a sphere together with the course modules. This system will dramatically improve the educational skill and increase interests of participators.

  13. Momentum-space Harper-Hofstadter model

    NASA Astrophysics Data System (ADS)

    Ozawa, Tomoki; Price, Hannah M.; Carusotto, Iacopo

    2015-08-01

    We show how the weakly trapped Harper-Hofstadter model can be mapped onto a Harper-Hofstadter model in momentum space. In this momentum-space model, the band dispersion plays the role of the periodic potential, the Berry curvature plays the role of an effective magnetic field, the real-space harmonic trap provides the momentum-space kinetic energy responsible for the hopping, and the trap position sets the boundary conditions around the magnetic Brillouin zone. Spatially local interactions translate into nonlocal interactions in momentum space: within a mean-field approximation, we show that increasing interparticle interactions leads to a structural change of the ground state, from a single rotationally symmetric ground state to degenerate ground states that spontaneously break rotational symmetry.

    We developed an educational program of space science data and science data observed from the space using a digital globe system, Dagik Earth. Dagik Earth is a simple and affordable four dimensional (three dimension in space and one dimension in time) presentation system. The educational program using Dagik Earth has been carried out in classrooms of schools, science museums, and research institutes to show the scientific data of the earth and planets in an intuitive way. We are developing the hardware system, data contents, and education manuals in cooperation with teachers, museum staffs and scientists. The size of the globe used in this system is from 15cm to 2m in diameter. It is selected according to the environment of the presentation. The contents cover the space science, such as aurora and geomagnetic field, the earth science, such as global clouds and earthquakes, and planetary science. Several model class plans are ready to be used in high school and junior high school. In public outreach programs of universities, research institutes, and scientific meetings, special programs have been carried out. We are establishing a community to use and develop this program for the space science education.

    ESERO Romania (The European Space Education Resource Office - Romania) has been established in 2014 as a collaboration between the Europen Space Agency and the Romanian Space Agency. The key aim of ESERO Romania is to increase STEM literacy in Romania by using space as an appealing context to make the teaching and learning of Science, Technology, Engineering and Math subjects more attractive and accessible. In Romania, the Office intends to bridge the gap between the prize-winning elites and the scientifically illiterate mass through the training of teachers, through raising awareness of space activities and through the dissemination of materials, making full use of ESA’s literature and logistical support in this process. The Romanian ESERO is also serving as the main interface between ESA Education and the Romanian educational community. The ultimate aim is to assure the formation of a future work force active in the space and engineering fields - including astronomy. This paper will outline the ways in which ESERO Romania contributes to space and astronomy education in Romania, as well as the challenges and opportunities encountered during the first year of its existence.

    2014-01-01

    The International Space Station (ISS) has a unique ability to capture the imagination of both students and teachers worldwide. Since 2000, the presence of humans onboard ISS has provided a foundation for numerous educational activities aimed at capturing that interest and motivating study in the sciences, technology, engineering and mathematics (STEM). Over 43 million students around the world have participated in ISS-related educational activities. Projects such as YouTube Space Lab, Sally Ride Earth Knowledge-based Acquired by Middle Schools (EarthKAM), SPHERES (Synchronized Position Hold Engage and Reorient Experimental Satellites) Zero-Robotics, Tomatosphere, and MAI-75 events among others have allowed for global student, teacher and public access to space through student classroom investigations and real-time audio and video contacts with crewmembers. Educational activities are not limited to STEM but encompass all aspects of the human condition. This is well illustrated in the Uchu Renshi project, a chain poem initiated by an astronaut while in space and continued and completed by people on Earth. With ISS operations now extended to 2024, projects like these and their accompanying educational materials are available to more students around the world. From very early on in the program's history, students have been provided with a unique opportunity to get involved and participate in science and engineering projects. Many of these projects support inquiry-based learning that allows students to ask questions, develop hypothesis-derived experiments, obtain supporting evidence and identify solutions or explanations. This approach to learning is well-published as one of the most effective ways to inspire students to pursue careers in scientific and technology fields. Ever since the first space station element was launched, a wide range of student experiments and educational activities have been performed, both individually and collaboratively, by all the

    This paper seeks to identify and explore some of the tensions that nurse educators face when engaging in the competing internal and external demands that are made on their delivery of curricula. It offers that one of the ways to explore these tensions constructively is to see them dialectically. It seeks to identify three archetypal dialectical themes that can be present in our teaching and offers that the educator's role can be understood to be one of a shaman as they seek to resolve these dialectical tensions skillfully.

    Multivariable parametric cost models for space telescopes provide several benefits to designers and space system project managers. They identify major architectural cost drivers and allow high-level design trades. They enable cost-benefit analysis for technology development investment. And, they provide a basis for estimating total project cost. A survey of historical models found that there is no definitive space telescope cost model. In fact, published models vary greatly [1]. Thus, there is a need for parametric space telescopes cost models. An effort is underway to develop single variable [2] and multi-variable [3] parametric space telescope cost models based on the latest available data and applying rigorous analytical techniques. Specific cost estimating relationships (CERs) have been developed which show that aperture diameter is the primary cost driver for large space telescopes; technology development as a function of time reduces cost at the rate of 50% per 17 years; it costs less per square meter of collecting aperture to build a large telescope than a small telescope; and increasing mass reduces cost.

    Researching and forecasting the ever changing space environment (often referred to as space weather) and its influence on humans and their activities are model-intensive disciplines. This is true because the physical processes involved are complex, but, in contrast to terrestrial weather, the supporting observations are typically sparse. Models play a vital role in establishing a physically meaningful context for interpreting limited observations, testing theory, and producing both nowcasts and forecasts. For example, with accurate forecasting of hazardous space weather conditions, spacecraft operators can place sensitive systems in safe modes, and power utilities can protect critical network components from damage caused by large currents induced in transmission lines by geomagnetic storms.

    The National Space Biomedical Research Institute (NSBRI) Education and Public Outreach Program (EPOP) is supporting the National Aeronautics and Space Administration's (NASA) new vision for space exploration by educating and inspiring the next generation of students through a seamless pipeline of kindergarten through postdoctoral education programs. NSBRI EPOP initiatives are designed to train scientists and to communicate the significance of NSBRI science, as well as other space exploration science, to schools, families and lay audiences. The NSBRI EPOP team is comprised of eight main partners: Baylor College of Medicine (BCM), Binghamton University-State University of New York (BUSUNY), Colorado Consortium for Earth and Space Science Education (CCESSE), Massachusetts Institute of Technology (MIT), Morehouse School of Medicine (MSM), Mount Sinai School of Medicine (MSSM), Rice University and the University of Texas Medical Branch (RU-UTMB), and Texas A&M University (TAMU). The current kindergarten through undergraduate college (K-16) team, which was funded through an open national competition in 2004, consolidates the past 7 years of K-16 education activities and expands the team's outreach activities to more museums and science centers across the nation. NSBRI also recently expanded its education mission to include doctoral and postdoctoral level programs. This paper describes select K-16 EPOP activities and products developed over the past 7 years, and reports on new activities planned for the next 3 years. The paper also describes plans for a doctoral program and reports on 1st-year outcomes of the new postdoctoral program.

    2012-12-01

    The need for a software toolkit that integrates space weather models and data is one of many challenges we are facing with when applying the models to space weather forecasting. To meet this challenge, we have developed Space Weather Integrated Modeling (SWIM) that is capable of analysis and visualizations of the results from a diverse set of space weather models. SWIM has a modular design and is written in Python, by using NumPy, matplotlib, and the Visualization ToolKit (VTK). SWIM provides data management module to read a variety of spacecraft data products and a specific data format of Solar-Interplanetary Conservation Element/Solution Element MHD model (SIP-CESE MHD model) for the study of solar-terrestrial phenomena. Data analysis, visualization and graphic user interface modules are also presented in a user-friendly way to run the integrated models and visualize the 2-D and 3-D data sets interactively. With these tools we can locally or remotely analysis the model result rapidly, such as extraction of data on specific location in time-sequence data sets, plotting interplanetary magnetic field lines, multi-slicing of solar wind speed, volume rendering of solar wind density, animation of time-sequence data sets, comparing between model result and observational data. To speed-up the analysis, an in-situ visualization interface is used to support visualizing the data 'on-the-fly'. We also modified some critical time-consuming analysis and visualization methods with the aid of GPU and multi-core CPU. We have used this tool to visualize the data of SIP-CESE MHD model in real time, and integrated the Database Model of shock arrival, Shock Propagation Model, Dst forecasting model and SIP-CESE MHD model developed by SIGMA Weather Group at State Key Laboratory of Space Weather/CAS.

    A non-recursive model (based on von Karman spectra) for atmospheric turbulence along the flight path of the shuttle orbiter was developed. It provides for simulation of instantaneous vertical and horizontal gusts at the vehicle center-of-gravity, and also for simulation of instantaneous gusts gradients. Based on this model the time series for both gusts and gust gradients were generated and stored on a series of magnetic tapes, entitled Shuttle Simulation Turbulence Tapes (SSTT). The time series are designed to represent atmospheric turbulence from ground level to an altitude of 120,000 meters. A description of the turbulence generation procedure is provided. The results of validating the simulated turbulence are described. Conclusions and recommendations are presented. One-dimensional von Karman spectra are tabulated, while a discussion of the minimum frequency simulated is provided. The results of spectral and statistical analyses of the SSTT are presented.

    2016-10-01

    It is obvious that Space Education is very important for sustainable space development as children are going to lead the new era of space development. The Japan Aerospace Exploration Agency (thereafter called "JAXA") believes that all children hold 3 spirits which are "Curiosity", "Adventure" and "Craftsmanship". We have been trying to ignite children's spirits toward nature, life and the universe with the effective use of space subjects and materials since the establishment of the JAXA Space Education Center in 2005. Studying about space is not limited to STEM, but can be applied to all subjects including social studies, music, and home economics. JAXA successfully coordinates more than 100 school classes in various subjects all over Japan each year. In geography, students learned geographical features of mountain ranges from images taken by JAXA's land observing satellite, while wearing 3D glasses so that they felt as if they were watching it from space. In home economics, students discussed and came up with ideas for new space food menu items considering nutrition and preservability. One of the ideas has been selected as Japanese Space Food. Nowadays, the numbers of school collaborations are stable and cover various subjects. Therefore JAXA cooperated with SHINSEI elementary school as a model school of space education. This elementary school introduced space studies in all grade's education guidelines in this school year. JAXA and SHINSEI elementary school are going to revise and analyze how students have been changed through this effort in March. We also focus on "Teacher Training" by holding JAXA-Teachers seminars all over Japan and more than 1000 teachers take this seminar every year. By studying a questionnaire survey taken from teacher seminars, it has been clarified that most of teachers realized space can be applied not only for astronomy but also in various subjects. They evaluate JAXA's effort for broadening their horizons. However most of teachers do

    Wang, Caroline K.

    1987-01-01

    A methodology for automatic mathematical modeling is described. The major objective is to create a very friendly environment for engineers to design, maintain and verify their model and also automatically convert the mathematical model into FORTRAN code for conventional computation. A demonstration program was designed for modeling the Space Shuttle Main Engine simulation mathematical model called Propulsion System Automatic Modeling (PSAM). PSAM provides a very friendly and well organized environment for engineers to build a knowledge base for base equations and general information. PSAM contains an initial set of component process elements for the Space Shuttle Main Engine simulation and a questionnaire that allows the engineer to answer a set of questions to specify a particular model. PSAM is then able to automatically generate the model and the FORTRAN code. A future goal is to download the FORTRAN code to the VAX/VMS system for conventional computation.

    2012-07-01

    A gradual change in the methods of teaching is setting in at all levels from primary education to postgraduate education. Astronomy, particularly being a big attraction for enthusiasts from outside the domain of science, demands different techniques. Use of table top dynamic models, black boards, simple calculations, graphical analysis and planetarium projections are of great relevance even before the students get to see through the telescope / binoculars. Depending on the age group role play can be an effective tool. Of late computer simulations and planetarium softwares have been playing a very important role in teaching. While it conveys the results of many experiments, demonstrations very effectively it also ignites the curious minds to continue on the activities. A small number of students who showed interest have successfully exploited the virtual observatories. The results from various space missions are also being used. I would like to present a few examples of such explorations which yielded interesting results - on the images of moon from Clemetine, Chandrayaan, the spectral analysis of stars from SDSS survey and using WEBDA for determining the ages of star clusters. Now I am seeing a new generation of students who use computers for quite sophisticated solutions. It is essential that we upgrade the teachers also to the same level. This workshop I am sure will provide a platform to discuss not only the advantages but the hurdles too.

    With the development of the International Space Station and the need for international collaboration for returning to the moon and developing a mission to Mars, NASA has embarked on developing international educational programs related to space exploration. In addition, with the explosion of educational technology, linking students on a global basis is more easily accomplished. This technology is bringing national and international issues into the classroom, including global environmental issues, the global marketplace, and global collaboration in space. We present the successes and lessons learned concerning international educational and public outreach programs that we have been involved in for NASA as well as the importance of sustaining these international peer collaborative programs for the future generations. These programs will undoubtedly be critical in enhancing the classroom environment and will affect the achievements in and attitudes towards science, technology, engineering and mathematics.

    Observational data sets generated by complex processes are common in ecology. Traditionally these have been very challenging to analyze because of the limitations of available statistical tools. This seems to be changing, and these are exciting times to be involved with ecological statistics, not just because of the neo-Bayesian revival but also because of the proliferation of computationally intensive methods in general. It is now possible to fit much richer models to observational data than in the relatively recent past, which in turn has stimulated much interest in how to evaluate and compare such models. In such an immature, vibrant, and rapidly growing field, not everyone is going to agree on the best way to do things. This is reflected in the contrast of opinions offered by the discussants. Each offers a thoughtful and thought-provoking critique of our work that reflects the current thinking in a non-negligible segment of the ecological data analysis community. We want to thank them for their insights.

    In the world of education the emotional life of the child has come in and out of focus. Psychoanalytic ideas and principles, including an emphasis on the individual, unconscious motivations, attachments, transferences, disavowed intentions, and feelings defended against, are in full operation within school settings. More recent developments in social-emotional skill promotion in schools and the emphasis on instilling skills such as perseverance and self-control have aims similar to psychoanalytic ideas of healthy ego functioning but use a more direct, didactic approach. We propose that the psychoanalytic school consultant can help bridge the gap between our wish to instill values and skills and some of the obstacles the individual student and school community might face. Through two case examples, one of a latency-age boy who struggled with aggressive impulses, and the other an adolescent caught in a "sexting" scandal, we delineate how the consultant using a psychoanalytic lens can intervene with the students, parents, faculty, and administration to facilitate the type of growth and education desired.

  11. Developing Viable Financing Models for Space Tourism

    Eilingsfeld, F.; Schaetzler, D.

    2002-01-01

    Increasing commercialization of space services and the impending release of government's control of space access promise to make space ventures more attractive. Still, many investors shy away from going into the space tourism market as long as they do not feel secure that their return expectations will be met. First and foremost, attracting investors from the capital markets requires qualifying financing models. Based on earlier research on the cost of capital for space tourism, this paper gives a brief run-through of commercial, technical and financial due diligence aspects. After that, a closer look is taken at different valuation techniques as well as alternative ways of streamlining financials. Experience from earlier ventures has shown that the high cost of capital represents a significant challenge. Thus, the sophistication and professionalism of business plans and financial models needs to be very high. Special emphasis is given to the optimization of the debt-to-equity ratio over time. The different roles of equity and debt over a venture's life cycle are explained. Based on the latter, guidelines for the design of an optimized loan structure are given. These are then applied to simulating the financial performance of a typical space tourism venture over time, including the calculation of Weighted Average Cost of Capital (WACC) and Net Present Value (NPV). Based on a concluding sensitivity analysis, the lessons learned are presented. If applied properly, these will help to make space tourism economically viable.

    Massinas, B. A.; Doufexopoulou, M.

    This paper focuses on basic teaching-orientation questions concerning the use of secondary products of informatics in space science education. These questions can be classified as relevant to: (a) the educational model, (b) the educational approach, (c) the determination of additional teaching material according to student needs. The relevant analysis is followed by the example of an introductory course on the Earth's gravity field, a topic touching upon many different areas within Earth and Space sciences. The course is designed with a view to enhancing the cognitive skills of individuals studying in either a formal or an informal educational setting. A Java applet, specifically created to illustrate the energy level change between surfaces of equal potential on and around the Earth, provides the core upon which one may gradually build all the topics within this wide field of study, according to the needs of the educator and the specialisation of the course.

    1990-01-01

    The objectives of this project were: (1) to investigate the implications of qualitative modeling techniques for problems arising in the monitoring, diagnosis, and design of Space Station subsystems and procedures; (2) to identify the issues involved in using qualitative models to enhance and automate engineering functions. These issues include representing operational criteria, fault models, alternate ontologies, and modeling continuous signals at a functional level of description; and (3) to develop a prototype collection of qualitative models for fluid and thermal systems commonly found in Space Station subsystems. Potential applications of qualitative modeling to space-systems engineering, including the notion of intelligent computer-aided engineering are summarized. Emphasis is given to determining which systems of the proposed Space Station provide the most leverage for study, given the current state of the art. Progress on using qualitative models, including development of the molecular collection ontology for reasoning about fluids, the interaction of qualitative and quantitative knowledge in analyzing thermodynamic cycles, and an experiment on building a natural language interface to qualitative reasoning is reported. Finally, some recommendations are made for future research.

    NASA Technical Reports Server (NTRS)

    Mitchell, Christine M.

    1992-01-01

    NASA space systems, including mission operations on the ground and in space, are complex, dynamic, predominantly automated systems in which the human operator is a supervisory controller. The human operator monitors and fine-tunes computer-based control systems and is responsible for ensuring safe and efficient system operation. In such systems, the potential consequences of human mistakes and errors may be very large, and low probability of such events is likely. Thus, models of cognitive functions in complex systems are needed to describe human performance and form the theoretical basis of operator workstation design, including displays, controls, and decision support aids. The operator function model represents normative operator behavior-expected operator activities given current system state. The extension of the theoretical structure of the operator function model and its application to NASA Johnson mission operations and space station applications is discussed.

    An extensive model analysis of plastic track detector measurements of high-LET particles on the Space Shuttle has been performed. Three shuttle flights: STS-51F (low-altitude, high-inclination), STS-51J (high-altitude, low-inclination), and STS-61C (low-altitude, low-inclination) are considered. The model includes contributions from trapped protons and galactic cosmic radiation, as well as target secondary particles. Target secondaries, expected to be of importance in thickly shielded space environments, are found to be a significant component of the measured LET (linear energy transfer) spectra.

    The International Space Station (ISS) has the unique ability to capture the imaginations of both students and teachers worldwide and thus stands as an invaluable learning platform for the advancement of proficiency in research and development and education. The presence of humans on board ISS for the past ten years has provided a foundation for numerous educational activities aimed at capturing that interest and motivating study in the sciences, technology, engineering and mathematics (STEM) disciplines which will lead to an increase in quality of teachers, advancements in research and development, an increase in the global reputation for intellectual achievement, and an expanded ability to pursue unchartered avenues towards a brighter future. Over 41 million students around the world have participated in ISS-related activities since the year 2000. Projects such as the Amateur Radio on International Space Station (ARISS) and Earth Knowledge Acquired by Middle School Students (EarthKAM), among others, have allowed for global student, teacher, and public access to space through radio contacts with crewmembers and student image acquisition respectively. . With planned ISS operations at least until 2020, projects like the aforementioned and their accompanying educational materials will be available to enable increased STEM literacy around the world. Since the launch of the first ISS element, a wide range of student experiments and educational activities have been performed by each of the international partner agencies: National Aeronautics and Space Administration (NASA), Canadian Space Agency (CSA), European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA) and Russian Federal Space Agency (Roscosmos). Additionally, a number of non-participating countries, some under commercial agreements, have also participated in Station-related activities. Many of these programs still continue while others are being developed and added to the station crewmembers tasks

  8. Mouse infection models for space flight immunology

    Several immunological processes can be affected by space flight. However, there is little evidence to suggest that flight-induced immunological deficits lead to illness. Therefore, one of our goals has been to define models to examine host resistance during space flight. Our working hypothesis is that space flight crews will come from a heterogeneous population; the immune response gene make-up will be quite varied. It is unknown how much the immune response gene variation contributes to the potential threat from infectious organisms, allergic responses or other long term health problems (e.g. cancer). This article details recent efforts of the Kansas State University gravitational immunology group to assess how population heterogeneity impacts host health, either in laboratory experimental situations and/or using the skeletal unloading model of space-flight stress. This paper details our use of several mouse strains with several different genotypes. In particular, mice with varying MHCII allotypes and mice on the C57BL background with different genetic defects have been particularly useful tools with which to study infections by Staphylococcus aureus, Salmonella typhimurium, Pasteurella pneumotropica and Ehrlichia chaffeensis. We propose that some of these experimental challenge models will be useful to assess the effects of space flight on host resistance to infection.

  9. Edgeworth streaming model for redshift space distortions

    2015-09-01

    We derive the Edgeworth streaming model (ESM) for the redshift space correlation function starting from an arbitrary distribution function for biased tracers of dark matter by considering its two-point statistics and show that it reduces to the Gaussian streaming model (GSM) when neglecting non-Gaussianities. We test the accuracy of the GSM and ESM independent of perturbation theory using the Horizon Run 2 N -body halo catalog. While the monopole of the redshift space halo correlation function is well described by the GSM, higher multipoles improve upon including the leading order non-Gaussian correction in the ESM: the GSM quadrupole breaks down on scales below 30 Mpc /h whereas the ESM stays accurate to 2% within statistical errors down to 10 Mpc /h . To predict the scale-dependent functions entering the streaming model we employ convolution Lagrangian perturbation theory (CLPT) based on the dust model and local Lagrangian bias. Since dark matter halos carry an intrinsic length scale given by their Lagrangian radius, we extend CLPT to the coarse-grained dust model and consider two different smoothing approaches operating in Eulerian and Lagrangian space, respectively. The coarse graining in Eulerian space features modified fluid dynamics different from dust while the coarse graining in Lagrangian space is performed in the initial conditions with subsequent single-streaming dust dynamics, implemented by smoothing the initial power spectrum in the spirit of the truncated Zel'dovich approximation. Finally, we compare the predictions of the different coarse-grained models for the streaming model ingredients to N -body measurements and comment on the proper choice of both the tracer distribution function and the smoothing scale. Since the perturbative methods we considered are not yet accurate enough on small scales, the GSM is sufficient when applied to perturbation theory.

  1. Habitability Concept Models for Living in Space

    NASA Astrophysics Data System (ADS)

    Ferrino, M.

    2002-01-01

    As growing trends show, living in "space" has acquired new meanings, especially considering the utilization of the International Space Station (ISS) with regard to group interaction as well as individual needs in terms of time, space and crew accommodations. In fact, for the crew, the Spaced Station is a combined Laboratory-Office/Home and embodies ethical, social, and cultural aspects as additional parameters to be assessed to achieve a user centered architectural design of crew workspace. Habitability Concept Models can improve the methods and techniques used to support the interior design and layout of space architectures and at the same time guarantee a human focused approach. This paper discusses and illustrates some of the results obtained for the interior design of a Habitation Module for the ISS. In this work, two different but complementary approaches are followed. The first is "object oriented" and based on Video Data (American and Russian) supported by Proxemic methods (Edward T. Hall, 1963 and Francesca Pregnolato, 1998). This approach offers flexible and adaptive design solutions. The second is "subject oriented" and based on a Virtual Reality environment. With this approach human perception and cognitive aspects related to a specific crew task are considered. Data obtained from these two approaches are used to verify requirements and advance the design of the Habitation Module for aspects related to man machine interfaces (MMI), ergonomics, work and free-time. It is expected that the results achieved can be applied to future space related projects.

    Parametric cost models are used to plan missions, compare concepts and justify technology investments. This paper reviews an on-going effort to develop cost modes for space telescopes. This paper summarizes the methodology used to develop cost models and documents how changes to the database have changed previously published preliminary cost models. While the cost models are evolving, the previously published findings remain valid: it costs less per square meter of collecting aperture to build a large telescope than a small telescope; technology development as a function of time reduces cost; and lower areal density telescopes cost more than more massive telescopes.

    1988-01-01

    This paper describes one of the most comprehensive models ever developed for a spacecraft electrical power system (EPS). The model was developed for the Hubble Space Telescope (HST) to evaluate vehicle power system performance and to assist in scheduling maintenance and refurbishment missions by providing data needed to forecast EPS power and energy margins for the mission phases being planned. The EPS model requires a specific mission phase description as the input driver and uses a high granularity database to produce a multi-orbit power system performance report. The EPS model accurately predicts the power system response to various mission timelines over the entire operational life of the spacecraft.

  5. Concepts of disability: the Activity Space Model.

    PubMed

    Kopec, J A

    1995-03-01

    This paper describes a new conceptual framework for functional assessment, the Activity Space Model (ASM). According to this model, functional impairments may lead to restrictions in an individual's activity space, a multidimensional space that represents human potential for activity. For each elementary ability, restrictions in the corresponding dimension of the activity space can be evaluated by deriving a difficulty curve that depicts the relationship between the level of performance and the psychophysical cost of activity. The effect of disease on daily functioning is explained in terms of a tradeoff between the psychophysical cost and the value of each act of behavior to the disabled individual. These two constructs are measured on the same scale and expressed in units of difficulty. The location of each task within the activity space in relation to the difficulty curve determines whether it will be performed or avoided at a given point in time. The ASM has both theoretical and practical implications. It offers a new, integrated perspective on disability and suggests new strategies for developing and evaluating functional assessment measures.

  10. Dynamic modelling and analysis of space webs

    NASA Astrophysics Data System (ADS)

    Yu, Yang; Baoyin, HeXi; Li, JunFeng

    2011-04-01

    Future space missions demand operations on large flexible structures, for example, space webs, the lightweight cable nets deployable in space, which can serve as platforms for very large structures or be used to capture orbital objects. The interest in research on space webs is likely to increase in the future with the development of promising applications such as Furoshiki sat-ellite of JAXA, Robotic Geostationary Orbit Restorer (ROGER) of ESA and Grapple, Retrieve And Secure Payload (GRASP) of NASA. Unlike high-tensioned nets in civil engineering, space webs may be low-tensioned or tensionless, and extremely flexible, owing to the microgravity in the orbit and the lack of support components, which may cause computational difficulties. Mathematical models are necessary in the analysis of space webs, especially in the conceptual design and evaluation for prototypes. A full three-dimensional finite element (FE) model was developed in this work. Trivial truss elements were adopted to reduce the computational complexity. Considering cable is a compression-free material and its tensile stiffness is also variable, we introduced the cable material constitutive relationship to work out an accurate and feasible model for prototype analysis and design. In the static analysis, the stress distribution and global deformation of the webs were discussed to get access to the knowledge of strength of webs with different types of meshes. In the dynamic analysis, special attention was paid to the impact problem. The max stress and global deformation were investigated. The simulation results indicate the interesting phenomenon which may be worth further research.

  11. Space physics games and simulations for informal education

    Harold, J.; Dusenbery, P.

    2008-12-01

    We will demonstrate and discuss several game and simulation based plasma physics education products. Developed using NSF education supplements and the long running Space Weather Outreach Program at the Space Science Institute, these activities range from a "mini-golf" game that uses research grade particle pushing algorithms, to a "whack the Earth" coronal mass ejection activity. These games have their roots in "informal" education settings: as a result they assume a short interaction time by the visitor (as compared to traditional classroom experiences), and they cannot assume a particular level of prior knowledge. On the other hand, as web based activities they have a tremendous reach, and are easily available for any instructor interested in using them in classroom environments. Several of the activities have also been programmed to collect data on the visitors' interactions, giving us a window in to both visitor engagement and the degree to which the activities accomplish their learning goals. In addition to exploring these results, we will discuss the next stage in the Space Weather Outreach Program, where we will explore the ability of a series of short games to build the necessary prior knowledge base for acquiring a firm grasp on basic space physics concepts.

    Fifty years ago the International Geophysical Year organized a unique and unprecedented program of research that united 60,000 scientists from 66 nations to study global phenomena concerning the Earth and its space environment. In that same spirit, "Space Weather Around the World" is a program to coordinate and facilitate the involvement of NASA heliophysics missions and scientists to inspire and educate a world-wide audience about the International Heliophysical Year (IHY). We will use the popular Sun-Earth Day annual event framework sponsored by the Sun-Earth Connection Education Forum to promote IHY science and the spirit of international collaboration. The theme for the March 2007 Sun-Earth Day: "IHY: Living in the Atmosphere of the Sun" was selected a year ago in anticipation of the IHY celebration. These efforts will be expanded through a series of coordinated programs under the theme "Space Weather Around the World" for Sun-Earth Day 2008. We will produce a live broadcast from China of the total solar eclipse on August 1st 2008 as the central event, highlighting investigations associated with the eclipse by the international heliophysics community. Additional collaborative efforts will include: a Space Weather Media Maker web-tool to allow educators and scientists to create their own multi-media resource to enhance teaching and learning at all levels; Rock-n-Sol, a musical composition by children internationally inspired by space weather and incorporating sonifications of solar data; and Space Weather Action Centers for students to track a solar storm featuring podcasts of multi-cultural perspectives on IHY. The anticipated audience would be millions of people internationally The science and E/PO heliophysics community has an exciting story to tell about IHY, and we look forward to the opportunity to share it globally.

The approach taken was to develop a set of models and tools for describing communications requirements, the algorithm resource requirements, the available hardware, and the alternative software architectures, and generate analysis data necessary to compare alternative designs. The Space Transceiver Analysis Tool (STAT) was developed to help users identify and select representative designs, calculate the analysis data, and perform a comparative analysis of the representative designs. The tool allows the design space to be searched quickly while permitting incremental refinement in regions of higher payoff.

  18. State-space models for multichannel detection

    Roman, J. R.; Davis, D. W.

    1993-07-01

    In multichannel identification and detection (or model-based multichannel detection) problems the parameters of a model are identified from the observed channel process and the identified model is used to facilitate the detection of a signal in the observe process. A model-based multichannel detection algorithm was developed in the context of an innovations-based detection algorithm (IBDA) formulation for surveillance radar system applications. The state space model class was adopted to model the vector channel process because it is more general than the time series model class used in most analyses to date. An IBDA methodology was developed based on the canonical correlations algorithm which for state-space model identification offers performance advantages over alternative techniques. A computer simulation was developed to validate the methodology and the algorithm, and to carry out performance assessments. Simulation results indicate that the algorithm is capable of discriminating between the null hypothesis (clutter plus noise) and the alternative hypothesis (signal plus clutter plus noise). In summary, the applicability of the approach to radar system problems was established.

    Space weather describes the various processes in the Sun-Earth system that present danger to human health and technology. The goal of space weather forecasting is to provide an opportunity to mitigate these negative effects. Physics-based space weather modeling is characterized by disparate temporal and spatial scales as well as by different physics in different domains. A multi-physics system can be modeled by a software framework comprising of several components. Each component corresponds to a physics domain, and each component is represented by one or more numerical models. The publicly available Space Weather Modeling Framework (SWMF) can execute and couple together several components distributed over a parallel machine in a flexible and efficient manner. The framework also allows resolving disparate spatial and temporal scales with independent spatial and temporal discretizations in the various models. Several of the computationally most expensive domains of the framework are modeled by the Block-Adaptive Tree Solar wind Roe Upwind Scheme (BATS-R-US) code that can solve various forms of the magnetohydrodynamics (MHD) equations, including Hall, semi-relativistic, multi-species and multi-fluid MHD, anisotropic pressure, radiative transport and heat conduction. Modeling disparate scales within BATS-R-US is achieved by a block-adaptive mesh both in Cartesian and generalized coordinates. Most recently we have created a new core for BATS-R-US: the Block-Adaptive Tree Library (BATL) that provides a general toolkit for creating, load balancing and message passing in a 1, 2 or 3 dimensional block-adaptive grid. We describe the algorithms of BATL and demonstrate its efficiency and scaling properties for various problems. BATS-R-US uses several time-integration schemes to address multiple time-scales: explicit time stepping with fixed or local time steps, partially steady-state evolution, point-implicit, semi-implicit, explicit/implicit, and fully implicit numerical

    A typical nine-week summer session of the International Space University includes 100 graduate students and young professionals from as many as thirty countries. In addition to lectures and team projects covering a variety of space-related disciplines, the curriculum contains several modes of cross-cultural education. In role- playing workshops, students (asked to behave in accord with known cultural norms of various countries) engage in negotiations on problems such as the rescue and return of astronauts as mandated in international agreements and treaties. Culture shock that could derail such negotiations in actual practice is observed, and the participants come away with heightened sensitivity to cultural differences. This technique could be extended to other educational settings, such as the activities of the UN's Regional Centres in developing countries and the outreach efforts associated with the International Heliophysical Year.

  6. Modelling early failures in Space Station Freedom

    Navard, Sharon E.

    1993-01-01

    A major problem encountered in planning for Space Station Freedom is the amount of maintenance that will be required. To predict the failure rates of components and systems aboard Space Station Freedom, the logical approach is to use data obtained from previously flown spacecraft. In order to determine the mechanisms that are driving the failures, models can be proposed, and then checked to see if they adequately fit the observed failure data obtained from a large variety of satellites. For this particular study, failure data and truncation times were available for satellites launched between 1976 and 1984; no data past 1984 was available. The study was limited to electrical subsystems and assemblies, which were studied to determine if they followed a model resulting from a mixture of exponential distributions.

    We briefly review the covariant formulation of the Green-Schwarz superstring by Berkovits, and describe how a detailed tree-level and one-loop analysis of this model leads, for the first time, to a derivation of the low-energy effective action of the heterotic superstring while keeping target-space supersymmetry manifest. The resulting low-energy theory is old-minimal supergravity coupled to tensor multiplet. The dilaton is part of the compensator multiplet.

    2006-01-01

    The Reference Architecture for Space Information Management (RASIM) suggests the separation of the data model from software components to promote the development of flexible information management systems. RASIM allows the data model to evolve independently from the software components and results in a robust implementation that remains viable as the domain changes. However, the development and management of data models within RASIM are difficult and time consuming tasks involving the choice of a notation, the capture of the model, its validation for consistency, and the export of the model for implementation. Current limitations to this approach include the lack of ability to capture comprehensive domain knowledge, the loss of significant modeling information during implementation, the lack of model visualization and documentation capabilities, and exports being limited to one or two schema types. The advent of the Semantic Web and its demand for sophisticated data models has addressed this situation by providing a new level of data model management in the form of ontology tools. In this paper we describe the use of a representative ontology tool to capture and manage a data model for a space information system. The resulting ontology is implementation independent. Novel on-line visualization and documentation capabilities are available automatically, and the ability to export to various schemas can be added through tool plug-ins. In addition, the ingestion of data instances into the ontology allows validation of the ontology and results in a domain knowledge base. Semantic browsers are easily configured for the knowledge base. For example the export of the knowledge base to RDF/XML and RDFS/XML and the use of open source metadata browsers provide ready-made user interfaces that support both text- and facet-based search. This paper will present the Planetary Data System (PDS) data model as a use case and describe the import of the data model into an ontology tool

  11. Creating State-based Alliances to Support Earth and Space Science Education Reform

    NASA Astrophysics Data System (ADS)

    2002-05-01

    Seven years after the publication of the National Science Education Standards and adoption of new state science education standards, Earth and space science remains outside the mainstream K-12 curriculum. Currently, less than ten percent of high school students in the United States of America take an Earth or space science course before graduation. This state of affairs is simply unacceptable. "All of us who live on this planet have the right and the obligation to understand Earth's unique history, its dynamic processes, its abundant resources, and its intriguing mysteries. As citizens of Earth, with the power to modify our climate and ecosystems, we also have a personal and collective responsibility to understand Earth so that we can make wise decisions about its and our future". As one step toward addressing this situation, we support the establishment of state-based alliances to promote Earth and space science education reform. "In many ways, states are the most vital locus of change in our nation's schools. State departments of education define curriculum frameworks, establish testing policies, support professional development and, in some cases, approve textbooks and materials for adoption". State alliance partners should include a broad spectrum of K-16 educators, scientists, policy makers, parents, and community leaders from academic institutions, businesses, museums, technology centers, and not-for profit organizations. The focus of these alliances should be on systemic and sustainable reform of K-16 Earth and space science education. Each state-based alliance should focus on specific educational needs within their state, but work together to share ideas, resources, and models for success. As we build these alliances we need to take a truly collaborative approach working with the other sciences, geography, and mathematics so that collectively we can improve the caliber and scope of science and mathematics education for all students.

    2005-01-01

    Creating an optical model of the Laser Interferometer Space antenna which can be used to predict optical sensitivities and set tolerances sufficiently well such that picometer level displacements can be reliably seen poses certain challenges. In part, because the distances between key optical elements, the proof masses, are constantly changing, at speeds of meters/second, the separation between them is about 5 million kilometers and a contributing factor to optical jitter is the self-gravity of the spacecraft. A discussion of the current state and future approach(s) to the creation of such an optical model will be presented.

  13. Space physics education via examples in the undergraduate physics curriculum

    2011-12-01

    The field of space physics is rich with examples of basic physics and analysis techniques, yet it is rarely seen in physics courses or textbooks. As space physicists in an undergraduate physics department we like to use research to inform teaching, and we find that students respond well to examples from magnetospheric science. While we integrate examples into general education courses as well, this talk will focus on physics major courses. Space physics examples are typically selected to illustrate a particular concept or method taught in the course. Four examples will be discussed, from an introductory electricity and magnetism course, a mechanics/nonlinear dynamics course, a computational physics course, and a plasma physics course. Space physics provides examples of many concepts from introductory E&M, including the application of Faraday's law to terrestrial magnetic storm effects and the use of the basic motion of charged particles as a springboard to discussion of the inner magnetosphere and the aurora. In the mechanics and nonlinear dynamics courses, the motion of charged particles in a magnetotail current sheet magnetic field is treated as a Newtonian dynamical system, illustrating the Poincaré surface-of-section technique, the partitioning of phase space, and the KAM theorem. Neural network time series analysis of AE data is used as an example in the computational physics course. Finally, among several examples, current sheet particle dynamics is utilized in the plasma physics course to illustrate the notion of adiabatic/guiding center motion and the breakdown of the adiabatic approximation. We will present short descriptions of our pedagogy and student assignments in this "backdoor" method of space physics education.

    This viewgraph presentation attempts to develop a model of factors which need to be considered in the design and construction of spacecraft to lessen the effects of space weather on these vehicles. Topics considered include: space environments and effects, radiation environments and effects, space weather drivers, space weather models, climate models, solar proton activity and mission design for the GOES mission. The authors conclude that space environment models need to address issues from mission planning through operations and a program to develop and validate authoritative space environment models for application to spacecraft design does not exist at this time.

    The future of the world is greatly depends on space. Through space sciences education programs with the main focus is on young people, the society, as a whole will gain in the years to come. The Weizmann Institute of Science is the leading scientific research center in Israel. After the need for science education programs for young students was recognized, the institute established its Youth Activities Section, which serves as the institute's outreach for the general population of school children nation-wide. The youth activities section holds courses, seminars, science camps etc. for almost 40 years. As an instructor in the youth activities section since 1990, my focus is space sciences programs, such as rocketry courses, planetarium demonstrations, astronomical observations and special events - all in the creed of bringing the space science to everyone, in a enjoyable, innovative and creative way. Two of the courses conducted combines' scientific knowledge, hands-on experience and a glimpse into the work of space programs: the rocketry courses offered a unique chance of design, build and fly actual rockets, to height of about 800 meters. The students conduct research on the rockets, such as aerial photography, environmental measurements and aerodynamic research - using student built wind tunnel. The space engineering course extend the high frontier of the students into space: the objective of a two year course is to design, build an launch an experiments package to space, using one of NASA's GAS programs. These courses, combined with special guest lectures by Weizmann institute's senior researchers, tours to facilities like satellite control center, clean rooms, the aeronautical industry, give the students a chance to meet with "the real world" of space sciences applications and industry, and this - in turn - will have payback effect on the society as a whole in years to come. The activities of space sciences education include two portable planetariums, 4

    The Community Coordinated Modeling Center (CCMC) hosts a set of state-of-the-art space science models ranging from the solar atmosphere to the Earth's upper atmosphere. CCMC provides a web-based Run-on-Request system, by which the interested scientist can request simulations for a broad range of space science problems. To allow the models to be driven by data relevant to particular events CCMC developed a tool that automatically downloads data from data archives and transform them to required formats. CCMC also provides a tailored web-based visualization interface for the model output, as well as the capability to download the simulation output in portable format. CCMC offers a variety of visualization and output analysis tools to aid scientists in interpretation of simulation results. During eight years since the Run-on-request system became available the CCMC archived the results of almost 3000 runs that are covering significant space weather events and time intervals of interest identified by the community. The simulation results archived at CCMC also include a library of general purpose runs with modeled conditions that are used for education and research. Archiving results of simulations performed in support of several Modeling Challenges helps to evaluate the progress in space weather modeling over time. We will highlight the scientific benefits of CCMC space science model archive and discuss plans for further development of advanced methods to interact with simulation results.

    2002-01-01

    'Under African Skies', a project of the charity organization Cosmos Education, undertook an excursion to sub-Saharan Africa to teach science and technology to children in primary and secondary schools. The role of science and technology for the purpose of development was emphasized, and the project directly addresses one of the recommendations of UNISPACE-III Vienna Declaration. Teaching primarily focused on astronomy and space science. Over 3500 primary and secondary school students in 5 different countries were reached. Although it is hard to quantify the impact of the teaching, the students' enthusiasm and questions demonstrated that they acquired knowledge and interest in science. In this talk we will summarize the objectives and achievements of the trip and future planned trips by Cosmos Education. We will also show coverage of the trip by the BBC program 'Final Frontier'. The youth perspective on education is outlined in the Global Space Education Curriculum, a project initiated at the UNISPACE III Space Generation Forum (SGF). This initiative is being further developed at the Space Generation Summit (SGS), an event at World Space Congress (WSC) that will unite international students and young professionals to develop a youth vision and strategy for the peaceful uses of space. SGS, endorsed by the United Nations, will take place from October 11-13th, during which the 200 delegates will discuss ongoing youth space activities, particularly those stemming from the UNISPACE-III/SGF and taken forward by the Space Generation Advisory Council. Delegates will address a variety of topics with the goal of devising new recommendations according to the theme, 'Accelerating Our Pace in Space'. The material presented here and in other technical sessions throughout WSC includes the results of these discussions.

    Kyushu University established International Centre for Space Weather Science and Education, shortly ICSWSE, in April 2012. The ICSWSE is leading two major research areas. One is magnetized environment of the Earth, and the other is space debris environment. Now, the ICSWSE fuses these two major research areas into one new project to contribute to the protection of space environment and space situational awareness. The ICSWSE has already established a technical and human network under the MAGnetic Data Acquisition System / Circum pan Pacific Magnetometer Array (MAGDAS/CPMN) project. Now, the ICSWSE is willing to establish a measurement network for space debris using small-aperture optical telescopes and small satellite constellation under the technical and human network, being named DEBris Data Acquisition System (DEBDAS). The telescopes are well organized to be robotically and remotely controlled, including sophisticated image processing techniques and orbit estimation software. The satellites are conducting in-situ measurements of micron-size debris using an easy-to-operate new sensor developed at JAXA. Data acquired from the systems will be analyzed and modeled in a manner coupled with space weather science to provide a better understanding of the present and future space debris environment. The ICSWSE also aims at education for practical astronomy and space engineering at Kyushu University, collaborative measurements in combination between robotic telescopes and small satellites, space environmental awareness and space science, including debris generation and resulting environment. Practical astronomy provides you with planning and observation, processing and detection, and origin identification. Space engineering provides you with small satellite design, production, and operation.

    The worksphere, a user controlled computer workstation enclosure, was expanded in scope to an engineering workstation suitable for use on the Space Station as a crewmember desk in orbit. The concept was also explored as a module control station capable of enclosing enough equipment to control the station from each module. The concept has commercial potential for the Space Station and surface workstation applications. The central triangular beam interior configuration was expanded and refined to seven different beam configurations. These included triangular on center, triangular off center, square, hexagonal small, hexagonal medium, hexagonal large and the H beam. Each was explored with some considerations as to the utilities and a suggested evaluation factor methodology was presented. Scale models of each concept were made. The models were helpful in researching the seven beam configurations and determining the negative residual (unused) volume of each configuration. A flexible hardware evaluation factor concept is proposed which could be helpful in evaluating interior space volumes from a human factors point of view. A magnetic version with all the graphics is available from the author or the technical monitor.

    2002-05-01

    Earth and Space Science is too often viewed as a peripheral science compared to chemistry, biology, and physics. It is typically found integrated with geography, ecology, and general science in various stages of the curriculum, and is rarely considered holistically or as a discrete discipline. The status of earth and space science is also commonly reflected in the inadequate preparation of teachers and in the lack of government recognition of the value of earth science education. Louisiana is a state that does not follow the typical trend. It is a leader in earth and space science education with its cadre of programs that impact teacher preparation, state testing programs, curriculum development and technology initiatives. The state science framework introduces earth science in middle school. Grades 5-7 have an integrated science curriculum that includes an earth science component. Grade 8 has either an earth science or an integrated science course depending upon the availability of certified teachers in the district. Earth science is also included in Louisiana's high school science curriculum. It satisfies one science credit required for graduation. The Louisiana Educational Assessment Program (LEAP 21) and the Graduation Exit Exam (GEE 21) compose Louisiana's new criterion-referenced testing program. The content standards measured by the LEAP 21/GEE 21science tests include earth and space science. The LEAP 21 is administered at grades 4 and 8, and the GEE 21 at grades 10 and 11. Students have to pass the GEE 21 to graduate from high school. Therefore, all students graduating from a Louisiana high school will have been exposed to earth science concepts multiple times throughout their K-12 schooling. Louisiana also has an array of programs that provide statewide curriculum and student resources and professional development that impact earth and space science education. The Making Connections Project provides web-site resources and lesson plans that have been

  2. Model reduction for Space Station Freedom

    NASA Technical Reports Server (NTRS)

    Williams, Trevor

    1992-01-01

    Model reduction is an important practical problem in the control of flexible spacecraft, and a considerable amount of work has been carried out on this topic. Two of the best known methods developed are modal truncation and internal balancing. Modal truncation is simple to implement but can give poor results when the structure possesses clustered natural frequencies, as often occurs in practice. Balancing avoids this problem but has the disadvantages of high computational cost, possible numerical sensitivity problems, and no physical interpretation for the resulting balanced 'modes'. The purpose of this work is to examine the performance of the subsystem balancing technique developed by the investigator when tested on a realistic flexible space structure, in this case a model of the Permanently Manned Configuration (PMC) of Space Station Freedom. This method retains the desirable properties of standard balancing while overcoming the three difficulties listed above. It achieves this by first decomposing the structural model into subsystems of highly correlated modes. Each subsystem is approximately uncorrelated from all others, so balancing them separately and then combining yields comparable results to balancing the entire structure directly. The operation count reduction obtained by the new technique is considerable: a factor of roughly r(exp 2) if the system decomposes into r equal subsystems. Numerical accuracy is also improved significantly, as the matrices being operated on are of reduced dimension, and the modes of the reduced-order model now have a clear physical interpretation; they are, to first order, linear combinations of repeated-frequency modes.

  3. Modeling utilization distributions in space and time

    Keating, K.A.; Cherry, S.

    2009-01-01

    W. Van Winkle defined the utilization distribution (UD) as a probability density that gives an animal's relative frequency of occurrence in a two-dimensional (x, y) plane. We extend Van Winkle's work by redefining the UD as the relative frequency distribution of an animal's occurrence in all four dimensions of space and time. We then describe a product kernel model estimation method, devising a novel kernel from the wrapped Cauchy distribution to handle circularly distributed temporal covariates, such as day of year. Using Monte Carlo simulations of animal movements in space and time, we assess estimator performance. Although not unbiased, the product kernel method yields models highly correlated (Pearson's r - 0.975) with true probabilities of occurrence and successfully captures temporal variations in density of occurrence. In an empirical example, we estimate the expected UD in three dimensions (x, y, and t) for animals belonging to each of two distinct bighorn sheep {Ovis canadensis) social groups in Glacier National Park, Montana, USA. Results show the method can yield ecologically informative models that successfully depict temporal variations in density of occurrence for a seasonally migratory species. Some implications of this new approach to UD modeling are discussed. ?? 2009 by the Ecological Society of America.

  4. Mathematical models for space shuttle ground systems

    Tory, E. G.

    1985-01-01

    Math models are a series of algorithms, comprised of algebraic equations and Boolean Logic. At Kennedy Space Center, math models for the Space Shuttle Systems are performed utilizing the Honeywell 66/80 digital computers, Modcomp II/45 Minicomputers and special purpose hardware simulators (MicroComputers). The Shuttle Ground Operations Simulator operating system provides the language formats, subroutines, queueing schemes, execution modes and support software to write, maintain and execute the models. The ground systems presented consist primarily of the Liquid Oxygen and Liquid Hydrogen Cryogenic Propellant Systems, as well as liquid oxygen External Tank Gaseous Oxygen Vent Hood/Arm and the Vehicle Assembly Building (VAB) High Bay Cells. The purpose of math modeling is to simulate the ground hardware systems and to provide an environment for testing in a benign mode. This capability allows the engineers to check out application software for loading and launching the vehicle, and to verify the Checkout, Control, & Monitor Subsystem within the Launch Processing System. It is also used to train operators and to predict system response and status in various configurations (normal operations, emergency and contingent operations), including untried configurations or those too dangerous to try under real conditions, i.e., failure modes.

    The possibility of substitution of trace elements such as Mg2+, Sr2+ and Ba2+ into the columnar Ca2+ positions of hydroxyapatite was examined by computer graphics with a personal computer and a space-cutting method. Data on the structural coordinates of the hydroxyapatite were put into a protein graphics program in Angstrom units. The connection of each element, with front and rear, was displayed by the shade-line erasing method, and the solidity of the image was expressed by the degree of lightness from the light source. The space-cutting model was obtained by selecting the cutting plane with three atoms in the crystal. Rotating the graphics freely around the X, Y and Z axes gives a view from any direction. The computer graphics suggested visually how the lattice dimensions expand with Sr2+ and Ba2+ substitution and contract with Mg2+ substitution.

    How do we reach the public with the exciting story of Solar System Exploration? How do we encourage girls to think about careers in science, math, engineering and technology? Why should NASA scientists make an effort to reach the public and informal education settings to tell the Solar System Exploration story? These are questions that the Solar System Exploration Forum, a part of the NASA Office of Space Science Education (SSE) and Public Outreach network, has tackled over the past few years. The SSE Forum is a group of education teams and scientists who work to share the excitement of solar system exploration with colleagues, formal educators, and informal educators like museums and youth groups. One major area of the SSE Forum outreach supports the training of Girl Scouts of the USA (GS) leaders and trainers in a suite of activities that reflect NASA missions and science research. Youth groups like Girl Scouts structure their activities as informal education.

    Advances in the ability to operate in, and thus to exploit, space have come more rapidly than almost anything else that has been done. From the beginning, nations have engaged in both cooperation and competition, from the stage of adventurous exploration to the current routine commercial activity. The Space Station program serves as a focus for the free world to move forward together, sharing both risks and benefits during the initial, formative period of an entirely new level of capability.

  8. Integrated Space Asset Management Database and Modeling

    Effective Space Asset Management is one key to addressing the ever-growing issue of space congestion. It is imperative that agencies around the world have access to data regarding the numerous active assets and pieces of space junk currently tracked in orbit around the Earth. At the center of this issues is the effective management of data of many types related to orbiting objects. As the population of tracked objects grows, so too should the data management structure used to catalog technical specifications, orbital information, and metadata related to those populations. Marshall Space Flight Center's Space Asset Management Database (SAM-D) was implemented in order to effectively catalog a broad set of data related to known objects in space by ingesting information from a variety of database and processing that data into useful technical information. Using the universal NORAD number as a unique identifier, the SAM-D processes two-line element data into orbital characteristics and cross-references this technical data with metadata related to functional status, country of ownership, and application category. The SAM-D began as an Excel spreadsheet and was later upgraded to an Access database. While SAM-D performs its task very well, it is limited by its current platform and is not available outside of the local user base. Further, while modeling and simulation can be powerful tools to exploit the information contained in SAM-D, the current system does not allow proper integration options for combining the data with both legacy and new M&S tools. This paper provides a summary of SAM-D development efforts to date and outlines a proposed data management infrastructure that extends SAM-D to support the larger data sets to be generated. A service-oriented architecture model using an information sharing platform named SIMON will allow it to easily expand to incorporate new capabilities, including advanced analytics, M&S tools, fusion techniques and user interface for

  9. Cognitive engineering models in space systems

    Mitchell, Christine M.

    1993-01-01

    NASA space systems, including mission operations on the ground and in space, are complex, dynamic, predominantly automated systems in which the human operator is a supervisory controller. Models of cognitive functions in complex systems are needed to describe human performance and form the theoretical basis of operator workstation design, including displays, controls, and decision aids. Currently, there several candidate modeling methodologies. They include the Rasmussen abstraction/aggregation hierarchy and decision ladder, the goal-means network, the problem behavior graph, and the operator function model. The research conducted under the sponsorship of this grant focuses on the extension of the theoretical structure of the operator function model and its application to NASA Johnson mission operations and space station applications. The initial portion of this research consists of two parts. The first is a series of technical exchanges between NASA Johnson and Georgia Tech researchers. The purpose is to identify candidate applications for the current operator function model; prospects include mission operations and the Data Management System Testbed. The second portion will address extensions of the operator function model to tailor it to the specific needs of Johnson applications. At this point, we have accomplished two things. During a series of conversations with JSC researchers, we have defined the technical goal of the research supported by this grant to be the structural definition of the operator function model and its computer implementation, OFMspert. Both the OFM and OFMspert have matured to the point that they require infrastructure to facilitate use by researchers not involved in the evolution of the tools. The second accomplishment this year was the identification of the Payload Deployment and Retrieval System (PDRS) as a candidate system for the case study.

    2005-05-01

    I will describe a community-wide educator enrichment program in the Earth and Space Sciences that is being developed at Halibut Point State Park in Rockport, MA. Through wide-ranging partnerships, we will provide two on-site hands-on workshops in Earth and Space Science that will serve the interests of school teachers, scout leaders, park interpreters, amateur astronomers, and other community educators. Each 3-day workshop will address the 3 broad topics of (1) living on Earth, (2) the Earth in space, and (3) the origins of the Earth, Solar System, Milky Way, and Universe. Natural resources at Halibut Point State Park will be used to enrich each of these topics. Astrobiology will be the topical "glue" that binds all 3 topics. Research of the PI will be featured through personal presentations on starbirth and starburst activity in galaxies. A wide selection of NASA education materials will be showcased -- including those developed for Project ASTRO, Family ASTRO, Great Explorations in Math and Science (GEMS), EarthKam, the Night Sky Network, and the Spitzer E/PO Program. These workshops will serve as models for similar programs in Earth and Space Science Education at state and national parks throughout the United States.

    Chaconas, Karen; Nashman, Marilyn; Lumia, Ronald

    1992-01-01

    This paper describes a method for tracking moving image features by combining spatial and temporal edge information with model based feature information. The algorithm updates the two-dimensional position of object features by correlating predicted model features with current image data. The results of the correlation process are used to compute an updated model. The algorithm makes use of a high temporal sampling rate with respect to spatial changes of the image features and operates in a real-time multiprocessing environment. Preliminary results demonstrate successful tracking for image feature velocities between 1.1 and 4.5 pixels every image frame. This work has applications for docking, assembly, retrieval of floating objects and a host of other space-related tasks.

    To investigate ophthalmic changes in spaceflight, we would like to predict the impact of blood dysregulation and elevated intracranial pressure (ICP) on Intraocular Pressure (IOP). Unlike other physiological systems, there are very few lumped parameter models of the eye. The eye model described here is novel in its inclusion of the human choroid and retrobulbar subarachnoid space (rSAS), which are key elements in investigating the impact of increased ICP and ocular blood volume. Some ingenuity was required in modeling the blood and rSAS compartments due to the lack of quantitative data on essential hydrodynamic quantities, such as net choroidal volume and blood flowrate, inlet and exit pressures, and material properties, such as compliances between compartments.

  13. Modeling gene expression in time and space.

    Rué, Pau; Garcia-Ojalvo, Jordi

    2013-01-01

    Cell populations rarely exhibit gene-expression profiles that are homogeneous in time and space. In the temporal domain, dynamical behaviors such as oscillations and pulses of protein production pervade cell biology, underlying phenomena as diverse as circadian rhythmicity, cell cycle control, stress and damage responses, and stem-cell pluripotency. In multicellular populations, spatial heterogeneities are crucial for decision making and development, among many other functions. Cells need to exquisitely coordinate this temporal and spatial variation to survive. Although the spatiotemporal character of gene expression is challenging to quantify experimentally at the level of individual cells, it is beneficial from the modeling viewpoint, because it provides strong constraints that can be probed by theoretically analyzing mathematical models of candidate gene and protein circuits. Here, we review recent examples of temporal dynamics and spatial patterning in gene expression to show how modeling such phenomenology can help us unravel the molecular mechanisms of cellular function.

    The Capitol College Center for Space Science Education and Public Outreach is in its second year of operation working to address the clearly articulated national need of providing an educated workforce in the science, technology, engineering and math (STEM) fields. Working with the K-12, community college and college students, the Center is actively engaged in providing learning opportunities for future leaders in STEM. This goal is accomplished through the following methods: 1. Increase student awareness of selected astronomy/space science career fields that require a college education, including necessary academic preparation related to STEM courses in high school. 2. Increase the number of community college students, specifically within the traditionally under-represented populations, advance to the bachelor's level degree within the STEM fields and then secure jobs within the field. 3. Increase STEM participation/majors in general (both in community colleges and four-year colleges), and especially NASA-related disciplines. This presentation provides an update regarding the Center's activities, reports on the year-one results working with middle schools and high schools in the state of Maryland and the Prince George's Community College, and highlights plans for the future.

    Space Weather is a relatively new discipline that studies the sun and Earth as a connected system with much relevance to our technological society. The Space Weather Living History project has gathered stories of observations, discoveries, events and impacts to build a timeline that will highlight the contributions of many scientists. In particular, pioneers and leaders who are active from the International Geophysical Year (IGY) to the present share their personal stories of how they are creating the history of space weather. The goal is to capture not just anecdotes, but careful analogies and insights of researchers and historians associated with various programs and events. Original historical materials also known as primary sources will allow both science and education communities to tell the stories of pioneers and leaders in space weather studies. Utilizing interactive media, this program aims to address important STEM needs, inspire the next generation of explorers, and feature women as role model. The products will align with Appendix H of the Next Generation Science Standards, the Nature of Science, where it is emphasized that 'science knowledge is cumulative and many people, from many generations and nations, have contributed to science knowledge.' This project augments existing historical records with education technology; connect the pioneers, current leaders and the nature and history of space weather with students, educators and the public, covering all areas of studies in Heliophysics. The project is supported by NASA award NNX11AJ61G.

  20. Fock spaces for modeling macromolecular complexes

    NASA Astrophysics Data System (ADS)

    Kinney, Justin

    Large macromolecular complexes play a fundamental role in how cells function. Here I describe a Fock space formalism for mathematically modeling these complexes. Specifically, this formalism allows ensembles of complexes to be defined in terms of elementary molecular ``building blocks'' and ``assembly rules.'' Such definitions avoid the massive redundancy inherent in standard representations, in which all possible complexes are manually enumerated. Methods for systematically computing ensembles of complexes from a list of components and interaction rules are described. I also show how this formalism readily accommodates coarse-graining. Finally, I introduce diagrammatic techniques that greatly facilitate the application of this formalism to both equilibrium and non-equilibrium biochemical systems.

    The Space Asset Management Database (SAM-D) was implemented in order to effectively track known objects in space by ingesting information from a variety of databases and performing calculations to determine the expected position of the object at a specified time. While SAM-D performs this task very well, it is limited by technology and is not available outside of the local user base. Modeling and simulation can be powerful tools to exploit the information contained in SAM-D. However, the current system does not allow proper integration options for combining the data with both legacy and new M&S tools. A more capable data management infrastructure would extend SAM-D to support the larger data sets to be generated by the COI. A service-oriented architecture model will allow it to easily expand to incorporate new capabilities, including advanced analytics, M&S tools, fusion techniques and user interface for visualizations. Based on a web-centric approach, the entire COI will be able to access the data and related analytics. In addition, tight control of information sharing policy will increase confidence in the system, which would encourage industry partners to provide commercial data. SIMON is a Government off the Shelf information sharing platform in use throughout DoD and DHS information sharing and situation awareness communities. SIMON providing fine grained control to data owners allowing them to determine exactly how and when their data is shared. SIMON supports a micro-service approach to system development, meaning M&S and analytic services can be easily built or adapted. It is uniquely positioned to fill this need as an information-sharing platform with a proven track record of successful situational awareness system deployments. Combined with the integration of new and legacy M&S tools, a SIMON-based architecture will provide a robust SA environment for the NASA SA COI that can be extended and expanded indefinitely.

    The UCLA Space Physics Group has developed educational software composed of a series of modules to assist students with understanding basic concepts of space plasmas and charged particle motion. Present modules cover planetary magnetospheres, charged particle motion, cold plasma waves, collisionless shock waves, and solar wind. The software is designed around the principle that students can learn more by doing rather than by reading or listening. The programs provide a laboratory-like environment in which the student can control, observe, and measure complex behavior. The interactive graphics environment allows the student to visualize the results of his or her experimentation and to try different parameters as desired. The current version of the software runs on UNIX-based operating systems in an X-Windows environment. It has been used in a classroom setting at both UCLA and the University of California at San Diego.

    The Community Coordinated Modeling Center (CCMC) is a US inter-agency activity aiming at research in support of the generation of advanced space weather models. As one of its main functions, the CCMC provides to researchers the use of space science models, even if they are not model owners themselves. The second focus of CCMC activities is on validation and verification of space weather models, and on the transition of appropriate models to space weather forecast centers. As part of the latter activity, the CCMC develops real-time simulation systems that stress models through routine execution. A by-product of these real-time calculations is the ability to derive model products, which may be useful for space weather operators. In this presentation, we will provide an overview of the community-provided, space weather-relevant, model suite, which resides at CCMC. We will discuss current capabilities, and analyze expected future developments of space weather related modeling.

  11. Granger causality for state-space models

    NASA Astrophysics Data System (ADS)

    Barnett, Lionel; Seth, Anil K.

    2015-04-01

    Granger causality has long been a prominent method for inferring causal interactions between stochastic variables for a broad range of complex physical systems. However, it has been recognized that a moving average (MA) component in the data presents a serious confound to Granger causal analysis, as routinely performed via autoregressive (AR) modeling. We solve this problem by demonstrating that Granger causality may be calculated simply and efficiently from the parameters of a state-space (SS) model. Since SS models are equivalent to autoregressive moving average models, Granger causality estimated in this fashion is not degraded by the presence of a MA component. This is of particular significance when the data has been filtered, downsampled, observed with noise, or is a subprocess of a higher dimensional process, since all of these operations—commonplace in application domains as diverse as climate science, econometrics, and the neurosciences—induce a MA component. We show how Granger causality, conditional and unconditional, in both time and frequency domains, may be calculated directly from SS model parameters via solution of a discrete algebraic Riccati equation. Numerical simulations demonstrate that Granger causality estimators thus derived have greater statistical power and smaller bias than AR estimators. We also discuss how the SS approach facilitates relaxation of the assumptions of linearity, stationarity, and homoscedasticity underlying current AR methods, thus opening up potentially significant new areas of research in Granger causal analysis.

    A computer program for the application of parameter identification on the structural dynamic models of space shuttle and other large models with hundreds of degrees of freedom is described. Finite element, dynamic, analytic, and modal models are used to represent the structural system. The interface with math models is such that output from any structural analysis program applied to any structural configuration can be used directly. Processed data from either sine-sweep tests or resonant dwell tests are directly usable. The program uses measured modal data to condition the prior analystic model so as to improve the frequency match between model and test. A Bayesian estimator generates an improved analytical model and a linear estimator is used in an iterative fashion on highly nonlinear equations. Mass and stiffness scaling parameters are generated for an improved finite element model, and the optimum set of parameters is obtained in one step.

    Upon introduction to microgravity, the near-loss of hydrostatic pressure causes a marked cephalic (headward) shift of fluid in an astronaut's body. The fluid shift, along with other factors of spaceflight, induces a cascade of interdependent physiological responses which occur at varying time scales. Long-duration missions carry an increased risk for the development of the Visual Impairment and Intracranial Pressure (VIIP) syndrome, a spectrum of ophthalmic changes including posterior globe flattening, choroidal folds, distension of the optic nerve sheath, kinking of the optic nerve and potentially permanent degradation of visual function. In the cases of VIIP found to date, the initial onset of symptoms occurred after several weeks to several months of spaceflight, by which time the gross bodily fluid distribution is well established. We are developing a suite of numerical models to simulate the effects of fluid shift on the cardiovascular, central nervous and ocular systems. These models calculate the modified mean volumes, flow rates and pressures that are characteristic of the altered quasi-homeostatic state in microgravity, including intracranial and intraocular pressures. The results of the lumped models provide initial and boundary data to a 3D finite element biomechanics simulation of the globe, optic nerve head and retrobulbar subarachnoid space. The integrated set of models will be used to investigate the evolution of the biomechanical stress state in the ocular tissues due to long-term exposure to microgravity.

  19. Space Power System Modeling with EBAL

    2006-07-01

    Pratt and Whitney Rocket dyne's Engine Balance (EBAL) thermal/fluid system code has been expanded to model nuclear power closed Brayton cycle (CBC) power conversion systems. EBAL was originally developed to perform design analysis of hypersonic vehicle propellant and thermal management systems analysis. Later, it was adapted to rocket engine cycles. The new version of EBAL includes detailed, physics-based models of all key CBC system components. Some component examples are turbo-alternators, heat exchangers, heat pipe radiators, and liquid metal pumps. A liquid metal cooled reactor is included and a gas cooled reactor model is in work. Both thermodynamic and structural analyses are performed for each component. EBAL performs steady-state design analysis with optimization as well as off-design performance analysis. Design optimization is performed both at the component level by the component models and on the system level with a global optimizer. The user has the option to manually drive the optimization process or run parametric analysis to better understand system trade-off. Although recent EBAL developments have focused on a CBC conversion system, the code is easily extendible to other power conversion cycles. This new, more powerful version of EBAL allows for rapid design analysis and optimization of space power systems. A notional example of EBAL's capabilities is included. (authors)

    Accordingly the United States Census Bureau, the ethnic group adding the largest number of people to the national population is the Hispanic exceeding 12 percent of the population and growing by almost 60 percent between 1990 and 2000. The status of the nation's educational system with respect to Hispanic students is perhaps one of the most influential issues facing the largest economy of the world. The low income, lack of language skills, highest drop-out rate in the nation, are some of the reasons why Hispanics are less likely to receive a university degree than any other ethical group. In short, the government requires to implement compensatory programs and bilingual education to ensure global leadership. Because of ongoing immigration, Spanish persists longer among Hispanics than it did among other immigrant groups. Spanish is the fourth most spoken language in the world after Mandarin, Hindustani and English. Although not all U.S. Hispanics speak Spanish, almost all U.S. Spanish speakers are Hispanics. This paper is intended to outline the challenging implementation of a bilingual education project affiliated to NASA Johnson Space Center encouraging greater academic success of Hispanics in engineering, math and science. The prospective project covers the overall role of space activities in the development of science and technology, socioeconomic issues and international cooperation. An existent JSC project is the starting stage to keep on developing an interactive video teleconference and web-media technology and produce stimulating learning products in English and Spanish for students and teachers across the nation and around the world.

  6. Model space diabatization for quantum photochemistry

    Li, Shaohong L.; Truhlar, Donald G.; Schmidt, Michael W.; Gordon, Mark S.

    2015-02-14

    Diabatization is a procedure that transforms multiple adiabatic electronic states to a new representation in which the potential energy surfaces and the couplings between states due to the electronic Hamiltonian operator are smooth, and the couplings due to nuclear momentum are negligible. In this work, we propose a simple and general diabatization strategy, called model space diabatization, that is applicable to multi-configuration quasidegenerate perturbation theory (MC-QDPT) or its extended version (XMC-QDPT). An advantage over previous diabatization schemes is that dynamical correlation calculations are based on standard post-multi-configurational self-consistent field (MCSCF) multi-state methods even though the diabatization is based on state-averaged MCSCF results. The strategy is illustrated here by applications to LiH, LiF, and thioanisole, with the fourfold-way diabatization and XMC-QDPT, and the results illustrate its validity.

    2016-08-01

    The density field reconstruction technique, which partially reverses the non-linear degradation of the Baryon acoustic oscillation (BAO) feature in the galaxy redshift surveys, has been successful in substantially improving the cosmology constraints from recent surveys such as Baryon Oscillation Spectroscopic Survey (BOSS). We estimate the efficiency of the method as a function of various reconstruction details. To directly quantify the BAO information in non-linear density fields before and after reconstruction, we calculate the cross-correlations (i.e. propagators) of the pre(post)-reconstructed density field with the initial linear field using a mock sample that mimics the clustering of the BOSS galaxies. The results directly provide the BAO damping as a function of wavenumber that can be implemented into the Fisher matrix analysis. We focus on investigating the dependence of the propagator on a choice of smoothing filters and on two major different conventions of the redshift-space density field reconstruction that have been used in literature. By estimating the BAO signal to noise for each case, we predict constraints on the angular diameter distance and Hubble parameter using the Fisher matrix analysis. We thus determine an optimal Gaussian smoothing filter scale for the signal-to-noise level of the BOSS CMASS. We also present appropriate BAO fitting models for different reconstruction methods based on the first- and second-order Lagrangian perturbation theory in Fourier space. Using the mock data, we show that the modified BAO fitting model can substantially improve the accuracy of the BAO position in the best fits as well as the goodness of the fits.

  9. Space Station crew safety - Human factors model

    1984-01-01

    A model of the various human factors issues and interactions that might affect crew safety is developed. The first step addressed systematically the central question: How is this Space Station different from all other spacecraft? A wide range of possible issue was identified and researched. Five major topics of human factors issues that interacted with crew safety resulted: Protocols, Critical Habitability, Work Related Issues, Crew Incapacitation and Personal Choice. Second, an interaction model was developed that would show some degree of cause and effect between objective environmental or operational conditions and the creation of potential safety hazards. The intermediary steps between these two extremes of causality were the effects on human performance and the results of degraded performance. The model contains three milestones: stressor, human performance (degraded) and safety hazard threshold. Between these milestones are two countermeasure intervention points. The first opportunity for intervention is the countermeasure against stress. If this countermeasure fails, performance degrades. The second opportunity for intervention is the countermeasure against error. If this second countermeasure fails, the threshold of a potential safety hazard may be crossed.

    The Community Coordinated Modeling Center (CCMC) is a US inter-agency activity aiming at research in support of the generation of advanced space weather models. As one of its main functions, the CCMC provides to researchers the use of space science models, even if they are not model owners themselves. The second CCMC activity is to support Space Weather forecasting at national Space Weather Forecasting Centers. This second activity involves model evaluations, model transitions to operations, and the development of space weather forecasting tools. Owing to the pace of development in the science community, new model capabilities emerge frequently. Consequently, space weather products and tools involve not only increased validity, but often entirely new capabilities. This presentation will review the present state of space weather tools as well as point out emerging future capabilities.

    2008-12-01

    As with all NASA missions, the Coupled Ion Neutral Dynamics Investigation (CINDI) is required to have an education and public outreach program (E/PO). Through our partnership between the University of Texas at Dallas William B. Hanson Center for Space Sciences and Department of Science/Mathematics Education, the decision was made early on to design our educational outreach around the needs of teachers. In the era of high-stakes testing and No Child Left Behind, materials that do not meet the content and process standards teachers must teach cannot be expected to be integrated into classroom instruction. Science standards, both state and National, were the fundamental drivers behind the designs of our curricular materials, professional development opportunities for teachers, our target grade levels, and even our popular informal educational resource, the "Cindi in Space" comic book. The National Science Education Standards include much more than content standards, and our E/PO program was designed with this knowledge in mind as well. In our presentation we will describe how we came to our approach for CINDI E/PO, and how we have been successful in our efforts to have CINDI materials and key concepts make the transition into middle school classrooms. We will also present on our newest materials and high school physics students and professional development for their teachers.

    Space and earth scientists often report that they would be happy to become engaged in valuable education and public outreach (EPO) activity if they were offered a feasible way to get started. Motivated by the need to offer scientists useful ideas and options for EPO involvement, we have created prototype versions of two interconnected, web-based resources: 1) the "Menu of Opportunities for Scientists in Education" (MOSIE) and 2) the "Roles Matrix". Our MOSIE prototype features EPO options collected from a small group of high-impact projects that are national in scope, with diverse geographic access, and ongoing opportunities for scientists to play valuable EPO roles. Featured projects currently include Project ASTRO, an NSF-supported national network of astronomer-teacher partnerships, and several traveling science center exhibits supported by NSF and/or NASA, such as MarsQuest, the Space Weather Center, and New Views of the Hubble Space Telescope. We are also featuring scientists from the MOSIE projects in our web-based "Roles Matrix", which includes profiles of actual space and earth scientists successfully engaged in EPO. The goals of this web-based Matrix are to: 1) recognize scientists successfully involved in education and public outreach (EPO); 2) raise awareness of the diversity of roles scientists can play in EPO besides classroom or public presentation; 3) document a representative sample of the ways scientists are currently involved in EPO; and 4) provide role models for scientists in personally rewarding and effective EPO involvement. We will evolve the Roles Matrix and MOSIE based on user feedback to maximize their value in promoting fruitful partnerships between EPO professionals and the communities in space and earth science. This work is supported by the NASA Office of Space Science and the NSF Geosciences Directorate.

    2016-01-01

    Potentially harmful stimuli occurring within the defensive peripersonal space (DPPS), a protective area surrounding the body, elicit stronger defensive reactions. The spatial features of the DPPS are poorly defined and limited to descriptive estimates of its extent along a single dimension. Here we postulated a family of geometric models of the DPPS, to address two important questions with respect to its spatial features: What is its fine-grained topography? How does the nervous system represent the body area to be defended? As a measure of the DPPS, we used the strength of the defensive blink reflex elicited by electrical stimulation of the hand (hand-blink reflex, HBR), which is reliably modulated by the position of the stimulated hand in egocentric coordinates. We tested the goodness of fit of the postulated models to HBR data from six experiments in which we systematically explored the HBR modulation by hand position in both head-centered and body-centered coordinates. The best-fitting model indicated that 1) the nervous system's representation of the body area defended by the HBR can be approximated by a half-ellipsoid centered on the face and 2) the DPPS extending from this area has the shape of a bubble elongated along the vertical axis. Finally, the empirical observation that the HBR is modulated by hand position in head-centered coordinates indicates that the DPPS is anchored to the face. The modeling approach described in this article can be generalized to describe the spatial modulation of any defensive response. PMID:26510762

    Measurement of stimulus-induced changes in activity in the brain is critical to the advancement of neuroscience. Scientists use a range of methods, including electrode implantation, surface (scalp) electrode placement, and optical imaging of intrinsic signals, to gather data capturing underlying signals of interest in the brain. These data are usually corrupted by artifacts, complicating interpretation of the signal; in the context of optical imaging, two primary sources of corruption are the heartbeat and respiration cycles. We introduce a new linear state-space framework that uses the Kalman filter to remove these artifacts from optical imaging data. The method relies on a likelihood-based analysis under the specification of a formal statistical model, and allows for corrections to the signal based on auxiliary measurements of quantities closely related to the sources of contamination, such as physiological processes. Furthermore, the likelihood-based modeling framework allows us to perform both goodness-of-fit testing and formal hypothesis testing on parameters of interest. Working with data collected by our collaborators, we demonstrate the method of data collection in an optical imaging study of a cat's brain.

    Korea has a short history in space development compared to neighboring countries like Japan, China, India and Russia. During the past 20 years, Korea has focused on developing satellite and rocket space technology under the national space development plan. KOMPSAT-1 and 2, and KSLV-1 are the results of the selection and concentration policy of the Korean government. Due to the arduous mission of developing hardware oriented space technology, the topic of space education and outreach for the general public has not received much in the national space program. But recently, the Korean government has begun planning a space science outreach program in the detailed action plan of the mid-long term national space development plan. This paper introduces and analyzes the organizations performing space education and outreach programs for primary and secondary schools in the Republic of Korea. "Young Astronaut Korea (YAK)" is one such program. This is a non-profit organization established to provide space education for students in 1989 when Korea just started its space development program. "YAK" is a unique group in Korea for space education and outreach activities because it is organized by branches at each school in the nation and it is much like the Boy Scout and Girl Scout programs. Space Science Museum and National Youth Space Center (NYSC), which are located near NARO space center in the southernmost part of the Korean peninsula are other examples of space education and outreach programs. NARO space center, which is the only launch site in Korea became the center of public interest by showing the KSLV-1 launch in 2009 and will be expected to play a key role for the space education of students in the Republic of Korea. The NYSC will perform many mission oriented space education programs for students as Space Camp in the USA does. This paper introduces the status of the space education and outreach programs of each organization and presents the future direction of space

This paper discusses study findings of the most recent unit, Food and Fitness, which teaches concepts related to energy and nutrition through guided inquiry. Results of a field test involving more than 750 students are reported. Use of the teaching materials resulted in significant knowledge gains by students as measured on a pre/post assessment administered by teachers. In addition, an analysis of the time spent by each teacher on each activity suggested that it is preferable to conduct all of the activities in the unit with students rather than allocating the same total amount of time on just a subset of the activities.

Space weather conditions are monitored to provide advance warning and forecasts based on observations and modeling using the integrated Space Weather Analysis Network (iSWA). Space weather forecasters come from a variety of backgrounds, ranging from modelers to astrophysicists to undergraduate students. This presentation will discuss space weather operations and research from an undergraduate perspective. The Space Weather Research, Education, and Development Initiative (SW REDI) is the starting point for many undergraduate opportunities in space weather forecasting and research. Space weather analyst interns play an active role year-round as entry-level space weather analysts. Students develop the technical and professional skills to forecast space weather through a summer internship that includes a two week long space weather boot camp, mentorship, poster session, and research opportunities. My unique development of research projects includes studying high speed stream events as well as a study of 20 historic, high-impact solar energetic particle events. This unique opportunity to combine daily real-time analysis with related research prepares students for future careers in Heliophysics.

    Most of higher education institutions provide certain area known as learning centre for their students to study or having group discussions. However, some of the learning centers are not provided by optimum number of tables and seats to accommodate the students sufficiently. This study proposed a new mathematical model in optimizing the number of tables and seats at Laman Najib, Faculty of Computer and Mathematical Sciences, Universiti Teknologi MARA (UiTM) Shah Alam. An improvement of space capacity with maximum number of students who can facilitate the Laman Najib at the same time has been made by considering the type and size of tables that are appropriate for student's discussions. Our finding is compared with the result of Simplex method of linear programming to ensure that our new model is valid and consistent with other existing approaches. As a conclusion, we found that the round-type tables with six seats provide the maximum number of students who can use Laman Najib for their discussions or group studying. Both methods are also practical to use as alternative approaches in solving other space optimization problems.

    Educator Academy is a K-12 STEM curriculum developed by the STEM K-12 Outreach Committee of the American Institute of Aeronautics and Astronautics (AIAA). Consisting of three independent curriculum modules, K-12 students participate in inquiry-based science and engineering challenges to improve critical thinking skills and enhance problem solving skills. The Space Weather Balloon Curriculum Module is designed for students in grades 9-12. Throughout this module, students learn and refine physics concepts as well as experimental research skills. Students participate in project-based learning that is experimental in nature. Students are engaged with the world around them as they collaborate to launch a high altitude balloon equipped with HD cameras.The program leaders launch high altitude weather balloons in collaboration with schools and students to teach physics concepts, experimental research skills, and to make space exploration accessible to students. A weather balloon lifts a specially designed payload package that is composed of HD cameras, GPS tracking devices, and other science equipment. The payload is constructed and attached to the balloon by the students with low-cost materials. The balloon and payload are launched with FAA clearance from a site chosen based on wind patterns and predicted landing locations. The balloon ascends over 2 hours to a maximum altitude of 100,000 feet where it bursts and allows the payload to slowly descend using a built-in parachute. The payload is located using the GPS device. In April 2012, the Space Weather Balloon team conducted a prototype field campaign near Fairbanks Alaska, sending several student-built experiments to an altitude of 30km, underneath several strong auroral displays. To better assist teachers in implementing one or more of these Curriculum Modules, teacher workshops are held to give teachers a hands-on look at how this curriculum is used in the classroom. And, to provide further support, teachers are each

    Examined here is the sensitivity of a variety of space experiments to residual accelerations. In all the cases discussed the sensitivity is related to the dynamic response of a fluid. In some cases the sensitivity can be defined by the magnitude of the response of the velocity field. This response may involve motion of the fluid associated with internal density gradients, or the motion of a free liquid surface. For fluids with internal density gradients, the type of acceleration to which the experiment is sensitive will depend on whether buoyancy driven convection must be small in comparison to other types of fluid motion, or fluid motion must be suppressed or eliminated. In the latter case, the experiments are sensitive to steady and low frequency accelerations. For experiments such as the directional solidification of melts with two or more components, determination of the velocity response alone is insufficient to assess the sensitivity. The effect of the velocity on the composition and temperature field must be considered, particularly in the vicinity of the melt-crystal interface. As far as the response to transient disturbances is concerned, the sensitivity is determined by both the magnitude and frequency of the acceleration and the characteristic momentum and solute diffusion times. The microgravity environment, a numerical analysis of low gravity tolerance of the Bridgman-Stockbarger technique, and modeling crystal growth by physical vapor transport in closed ampoules are discussed.

  10. Space education in developing countries in the information era, regional reality and new educational material tendencies: example, South America

    NASA Astrophysics Data System (ADS)

    Sausen, Tania Maria

    The initial activities on space education began right after World War II, in the early 1950s, when USA and USSR started the Space Race. At that time, Space education was only and exclusively available to researchers and technicians working directly in space programs. This new area was restricted only to post-graduate programs (basically master and doctoral degree) or to very specific training programs dedicated for beginners. In South America, at that time there was no kind of activity on space education, simply because there was no activity in space research. In the beginning of the 1970s, Brazil, through INPE, had created masteral and doctoral courses on several space areas such as remote sensing and meteorology. Only in the mid-1980s did Brazil, after a UN request, create its specialisation course on remote sensing dedicated to Latin American professionals. At the same period, the Agustin Codazzi Institute (Bogota, Colombia) began to offer specialisation courses in remote sensing. In South America, educational space programs are currently being created for elementary and high schools and universities, but the author personally estimates that 90% of these educational programs still make use of traditional educational materials — such as books, tutorials, maps and graphics. There is little educational material that uses multimedia resources, advanced computing or communication methods and, basically, these are the materials that are best suited to conduct instructions in remote sensing, GIS, meteorology and astronomy.

Once operational, it can also be used to capture the dreams of the world's children and connect the world's industry through education. The space station's global heritage and ownership; its complex engineering, construction, and operation; its flexible research and technology demonstration capability; and its long duration make it the perfect educational platform. These things also make a space station education program attractive to industry. Such a program will give private industry the opportunity to sponsor space-related activities even though a particular industry may not have a research or technology-driven need for space utilization. Sponsors will benefit through public relations and goodwill, educational promotions and advertising, and the sale and marketing of related products. There is money to be made by supporting, fostering, and enabling education in space through the International Space Station. This paper will explore various ISS education program and sponsorship options and benefits, will examine early industry response to such an opportunity, and will make the case for moving forward with an ISS education program as a private sector initiative.

    The National Space Science Data Center (NSSDC) was established by NASA in 1964 to provide for the preservation and dissemination of scientific data from NASA missions. It has evolved to support distributed, active archives that were established in the Planetary, Astrophysics, and Heliophysics disciplines through a series of Memoranda of Understanding. The disciplines took over responsibility for working with new projects to acquire and distribute data for community researchers while the NSSDC remained vital as a deep archive. Since 2000, NSSDC has been using the Archive Information Package to preserve data over the long term. As part of its effort to streamline the ingest of data into the deep archive, the NSSDC developed and implemented a data model of desired and required metadata in XML. This process, in use for roughly five years now, has been successfully used to support the identification and ingest of data into the NSSDC archive, most notably those data from the Planetary Data System (PDS) submitted under PDS3. A series of software packages (X-ware) were developed to handle the submission of data from the PDS nodes utilizing a volume structure. An XML submission manifest is generated at the PDS provider site prior to delivery to NSSDC. The manifest ensures the fidelity of PDS data delivered to NSSDC. Preservation metadata is captured in an XML object when NSSDC archives the data. With the recent adoption by the PDS of the XML-based PDS4 data model, there is an opportunity for the NSSDC to provide additional services to the PDS such as the preservation, tracking, and restoration of individual products (e.g., a specific data file or document), which was unfeasible in the previous PDS3 system. The NSSDC is modifying and further streamlining its data ingest process to take advantage of the PDS4 model, an important consideration given the ever-increasing amount of data being generated and archived by orbiting missions at the Moon and Mars, other active projects

    1987-01-01

    The development and testing of a mouse model for simulating some aspects of weightlessness that occurs during space flight, and the carrying out of immunological experiments on animals undergoing space flight is examined. The mouse model developed was an antiorthostatic, hypokinetic, hypodynamic suspension model similar to one used with rats. The study was divided into two parts. The first involved determination of which immunological parameters should be observed on animals flown during space flight or studied in the suspension model. The second involved suspending mice and determining which of those immunological parameters were altered by the suspension. Rats that were actually flown in Space Shuttle SL-3 were used to test the hypotheses.

    2015-12-01

    The Lunar Workshops for Educators (LWE) series was developed by the Lunar Reconnaissance Orbiter (LRO) education team in 2010 to provide professional development on lunar science and exploration concepts for grades 6-9 science teachers. Over 300 educators have been trained to date. The LWE model incorporates best practices from pedagogical research of science education, thoughtful integration of scientists and engineer subject matter experts for both content presentations and informal networking with educators, access to NASA-unique facilities, hands-on and data-rich activities aligned with education standards, exposure to the practice of science, tools for addressing common misconceptions, follow-up with participants, and extensive evaluation. Evaluation of the LWE model via pre- and post-assessments, daily workshop surveys, and follow-up surveys at 6-month and 1-year intervals indicate that the LWE are extremely effective in increasing educators' content knowledge, confidence in incorporating content into the classroom, understanding of the practice of science, and ability to address common student misconceptions. In order to address the efficacy of the LWE model for other science content areas, the Dynamic Response of Environments at Asteroids, the Moon, and moons of Mars (DREAM2) education team, funded by NASA's Solar System Exploration Research Virtual Institute, developed and ran a pilot workshop called Dream2Explore at NASA's Goddard Space Flight Center in June, 2015. Dream2Explore utilized the LWE model, but incorporated content related to the science and exploration of asteroids and the moons of Mars. Evaluation results indicate that the LWE model was effectively used for educator professional development on non-lunar content. We will present more detail on the LWE model, evaluation results from the Dream2Explore pilot workshop, and suggestions for the application of the model with other science content for robust educator professional development.

    2010-01-01

    In addition to supporting space research in the international community, the Community Coordinated Modeling Center (CCMC) has as its second objective to apply the power of modern research models toward space weather specification and forecasting. Motivated by the objectives to test models and to ease the transition of research models to space weather forecasting organizations, the CCMC has developed a number of real-time modeling systems, as well as a large number of modeling and data products for space weather forecasting support. Over time, these activities have produced tailored products for partners, as well as tools, which address the space weather needs of NASA's robotic mission community. All tools are accessible via a configurable, flexible interface. During this process, CCMC has accumulated substantial experience in understanding model performance, as well as in the design and execution of realtime systems. This presentation will focus on lessons learned and it will suggest low hanging fruit for transition to operations at partner agencies.

  2. Mainstream Issues of Education and Public Awareness of Space Activities and Sciences among universities and Scientific Institutes.

    NASA Astrophysics Data System (ADS)

    Singh, Balbir

    This paper is an effort to study and analyze several constraints and issues of space technology and education that organizations other than governmental organizations face in awareness program. In recent years, advancements in technologies have made it possible for Volunteer and Technical Communities, non-government organizations, private agencies and academic research institutions to provide increasing support to space education management and emphasis on response efforts. Important cornerstones of this effort and support are the possibility to access and take advantage of satellite imagery as well as the use of other space-based technologies such as telecommunications satellites and global navigation satellite systems included in main curriculum plus the implementation of programs for use of high class sophisticated technologies used by industries to the students and researchers of non-space faring nations. The authors recognize the importance of such new methodologies for education and public Awareness. This paper demonstrates many hurdles universities and scientific institutions face including lack of access in terms of financial and technical resources for better support. A new model for coordinated private sector partnership in response to space sciences and education has been discussed. In depth analysis and techniques need to connect these pioneering communities with the space industry as well as the space governmental agencies, with special emphasis on financial constraints. The paper mandates its role to promote the use of space-based information; its established networks bringing together national institutions responsible for these space based activities, as well as other end users, and space solution experts; and its technical foundation, particularly in the area of information technologies. To help building a tighter cooperation and further understanding among all these communities, paper delivers an intensive report and solutions for future

    2014-01-01

    Heart failure (HF) is the heart's inability to meet the body's need for blood and oxygen. According to the American Heart Association 2013 update, approximately 5.1 million people are diagnosed with HF in the United States in 2006. Heart failure is the most common diagnosis for hospitalization. In the United States, the HF direct and indirect costs are estimated to be US $39.2 billion in 2010. To address this issue, nursing educators designed innovative teaching frameworks on HF management both in academia and in clinical settings. The model was based on 2 resources: the American Association of Heart Failure Nurses (2012) national nursing certification and the award-winning Pierce County Responsive Care Coordination Program. The HF educational program is divided into 4 modules. The initial modules offer foundational levels of Bloom's Taxonomy then progress to incorporate higher-levels of learning when modules 3 and 4 are reached. The applicability of the key components within each module allows formatting to enhance learning in all areas of nursing, from the emergency department to intensive care units to the medical-surgical step-down units. Also applicable would be to provide specific aspects of the modules to nurses who care for HF patients in skilled nursing facility, rehabilitation centers, and in the home-health care setting.

    2005-12-01

    National and state parks provide space scientists with many opportunities for involvement in education and public outreach (E/PO). Towards these ends, NASA's Space Science E/PO Support Network can help initiate and foster the necessary partnerships between scientists and park personnel. For example, the professional development of national park interpreters has been pursued with the "Earth to Sky" program that was led by the Sun-Earth Connection Education Forum. Through partnerships with space scientists and E/PO professionals, park rangers are now developing interpretive products and programs to enrich the experiences of more than 100 million park visitors across the U.S. On a smaller scale, we have developed a community-wide educator enrichment program in the Earth and Space Sciences that is being implemented at Halibut Point State Park in Rockport, MA. Through wide-ranging partnerships, we are providing on-site hands-on workshops in Earth and Space Science that serve the interests of school teachers, scout leaders, park interpreters, amateur astronomers, and other community educators. Each 3-day workshop addresses the 3 broad topics of (1) living on Earth, (2) the Earth in space, and (3) our cosmic origins. Natural resources at Halibut Point State Park are used to enrich each of these topics. Astrobiology is the topical "glue" that binds all 3 topics. Research of the PI is featured through personal presentations on starbirth and starburst activity in galaxies. A wide selection of NASA education materials are showcased -- including those developed for Project ASTRO, Family ASTRO, Great Explorations in Math and Science (GEMS), EarthKam, the Night Sky Network, and the Spitzer E/PO Program. These workshops serve as models for similar programs in Earth and Space Science Education at state and national parks throughout the United States. WHW gratefully acknowledges support from a Spitzer E/PO grant supplement.

    2014-12-01

    NASA provides a wealth of data from Heliospheric missions to the public, but educators face several challenges to using such data in the classroom. These include the knowledge of what is available and how to use it, a full understanding of the science concepts the data demonstrate, ability to obtain and maintain products to access data, and access to technology (such as computer labs) for anything other than testing. To surmount these challenges, the Educator Resource Center at the NASA Independent Validation and Verification (IV&V) Center in Fairmont, WV has developed an operational model that focuses on housing, maintaining, and lending out kits of necessary equipment along with training educators in the science concepts and use of kit materials. Following this model, we have developed a Sun and Space Weather kit and an educator professional development course that we have presented several times. The kit includes a classroom set of iPads utilized to access data from NASA missions and other sources as well as create video reports for project based outcomes, a set of telescopes for safe solar viewing, and materials to explore magnetic fields and the electromagnetic spectrum. We will present an overview of the training course, the kit materials, and lessons learned.

    2004-12-01

    The development of new, relatively inexpensive immersive projection technologies (and portable inflatable fulldome theatres) have now allowed new ways of visualizing data and models. Students can be surrounded by moving imagery, allowing them to experience (and not just be told) about spatial and temporal variations, such as the dance of a Cluster orbit or the compression of field lines during a solar storm. Common misconceptions (such as the reason for the season) can be eliminated by experiences. Fulldome shows also allow a new exciting venue to bring space physics to the planetarium, a venue previously only showing starfields and planets. Now CMEs and solar storms can sweep over the public. New animation and visualization tools have been developed to maximize the experience, including riding on Cluster through an orbit while listening to the data stream from the four spacecraft. A demonstration of the immersive dome in action will be done if possible.

Major characteristics of the model are outlined and the model assumes a baroclinic Space Environment in view of observed pronounced horizontal electron temperature gradient with prevailing weak vertical temperature gradient. The primary objective of the study is to be able to monitor and realistically predict on real- or near real-time SW and Space Storms (SWS) affecting human economic systems on Earth as well as the safety and Physiologic comfort of human payload in Space Environment in relation to planned increase in human space flights especially with reference to the ISS Space Shuttle Taxi (ISST) Programme and other prolonged deep Space Missions. Although considerable discussions are now available in the literature on SW issues, routine Meteorological operational applications of SW forecast data and information for Space Environment are still yet to receive adequate attention. The paper attempts to fill this gap in the literature of SW. The paper examines the sensitivity and variability in 3-D continuum of Plasmas in response to solar radiation inputs into the magnetosphere under disturbed Sun condition. Specifically, the presence of plasma clouds in the form of Coronal Mass Ejections (CMEs) is stressed as a major source of danger to Space crews, spacecraft instrumentation and architecture charging problems as well as impacts on numerous radiation - sensitive human economic systems on Earth. Finally, the paper considers the application of model results in the form of effective monitoring of each of the two major phases of manned Spaceflights - take-off and re-entry phases where all-time assessment of spacecraft transient ambient micro-incabin and outside Space Environment is vital for all manned Spaceflights as recently evidenced by the loss of vital information during take-off of the February 1, 2003 US Columbia

    Green space system, as part of the urban ecological environment and urban landscape, plays a significant role in the protection of biological diversity of the urban eco-systems. During the process of rapid modernization in China, it is evident that in order to satisfy the residents' needs of entertainment and communication effectively; there should be abundant types and adequate arrangement of green space. And at the same time a comprehensive and stable hierarchical structure of green space system ought to be established. Huff Model is widely used in facility location planning and service area segmentation in business geography, and has potentials in urban facility planning and design. This paper aims to evaluate, design and optimize the urban green space in Luoyang City, Henan Province, using GIS and Huff Model. Considering the existing location, size and shape of the green space supply, the spatial distribution of residence and the urban transportation systems, the attractiveness between residence and green space is estimated. The spatial pattern and service capability of the green space system are also evaluated critically. Based on the findings, the possible optimization design of the green space system in Luoyang is discussed innovatively. Huff model test shows that the design improves the overall spatial accessibility observably. The case study shows that GIS technology and Huff Model have great potential in urban green space evaluation, planning and design.

    The space station must unite the properties and behavior of individual and place, using proportions from both to make whole the understanding of ourselves at this moment in evolution. Harmonious proportions in any environment are similar to the acceptance and enjoyment of the harmony of many well-tuned musical instruments. A well-tuned or well-ordered environment tends to have invisible proportions. They produce order but do not intrude on the perception and cognitive mapping of the environment. Systems of proportion are not ends in themselves but are a means to select a series of spaces which relate one to another in dimensionally specific terms. These internal relationships create a whole when the forms are harmonious. This harmonic relationship is of intrinsic value for individuals to be physically and psychologically in balance with their universe.

  17. Space Education Strategy Using Data Obtained by Lunar and Planetary Missions

    Japanese two lunar and planetary missions, Kaguya (SELENE) and Hayabusa (MUSES-C) are returning vast amount of result to the Earth, and these data are planned to open to the public via the Internet. These are considered useful not only for scientists and engineers but also for the educators and students as a “real textbook”. In space education, we can use several methods to facilitate students' interest. Here we describe some of our examples to promote space education. One is the event accompanying with the major conferences, and second is the video program describing the Hayabusa mission with very unique viewpoint, and the third is the website carefully designed for children. However, the application of mission results to the space education has some points which should be specific to these missions. This paper describes our current attempt of these application and future prospects for the promotion of space education.

  19. Development, validation and application of numerical space environment models

    NASA Astrophysics Data System (ADS)

    Honkonen, Ilja

    2013-10-01

    Currently the majority of space-based assets are located inside the Earth's magnetosphere where they must endure the effects of the near-Earth space environment, i.e. space weather, which is driven by the supersonic flow of plasma from the Sun. Space weather refers to the day-to-day changes in the temperature, magnetic field and other parameters of the near-Earth space, similarly to ordinary weather which refers to changes in the atmosphere above ground level. Space weather can also cause adverse effects on the ground, for example, by inducing large direct currents in power transmission systems. The performance of computers has been growing exponentially for many decades and as a result the importance of numerical modeling in science has also increased rapidly. Numerical modeling is especially important in space plasma physics because there are no in-situ observations of space plasmas outside of the heliosphere and it is not feasible to study all aspects of space plasmas in a terrestrial laboratory. With the increasing number of computational cores in supercomputers, the parallel performance of numerical models on distributed memory hardware is also becoming crucial. This thesis consists of an introduction, four peer reviewed articles and describes the process of developing numerical space environment/weather models and the use of such models to study the near-Earth space. A complete model development chain is presented starting from initial planning and design to distributed memory parallelization and optimization, and finally testing, verification and validation of numerical models. A grid library that provides good parallel scalability on distributed memory hardware and several novel features, the distributed cartesian cell-refinable grid (DCCRG), is designed and developed. DCCRG is presently used in two numerical space weather models being developed at the Finnish Meteorological Institute. The first global magnetospheric test particle simulation based on the

    Through independent and co-operational science missions, Strategic Pioneer Program (SPP) on Space Science, the new initiative of space science program in China which was approved by CAS and implemented by National Space Science Center (NSSC), dedicates to seek new discoveries and new breakthroughs in space science, thus deepen the understanding of universe and planet earth. In the framework of this program, in order to support the operations of space science missions and satisfy the demand of related research activities for e-Science, NSSC is developing a virtual space science research platform based on cloud model, namely the Space Science Cloud (SSC). In order to support mission demonstration, SSC integrates interactive satellite orbit design tool, satellite structure and payloads layout design tool, payload observation coverage analysis tool, etc., to help scientists analyze and verify space science mission designs. Another important function of SSC is supporting the mission operations, which runs through the space satellite data pipelines. Mission operators can acquire and process observation data, then distribute the data products to other systems or issue the data and archives with the services of SSC. In addition, SSC provides useful data, tools and models for space researchers. Several databases in the field of space science are integrated and an efficient retrieve system is developing. Common tools for data visualization, deep processing (e.g., smoothing and filtering tools), analysis (e.g., FFT analysis tool and minimum variance analysis tool) and mining (e.g., proton event correlation analysis tool) are also integrated to help the researchers to better utilize the data. The space weather models on SSC include magnetic storm forecast model, multi-station middle and upper atmospheric climate model, solar energetic particle propagation model and so on. All the services above-mentioned are based on the e-Science infrastructures of CAS e.g. cloud storage and

    2016-04-01

    Given conformal data on a flat Euclidean space, we use crosscap conformal bootstrap equations to numerically solve the Lee-Yang model as well as the critical Ising model on a three dimensional real projective space. We check the rapid convergence of our bootstrap program in two dimensions from the exact solutions available. Based on the comparison, we estimate that our systematic error on the numerically solved one-point functions of the critical Ising model on a three dimensional real projective space is less than 1%. Our method opens up a novel way to solve conformal field theories on nontrivial geometries.

    2002-01-01

    In April 2001 the German Aerospace Society DGLR e.V. in cooperation with the Technical University of Darmstadt, Germany initiated an interdisciplinary students contest, under the patronage of Mr. Joerg Feustel-Buechl, the Director of Manned Spaceflight and Microgravity, European Space Agency (ESA), for the summer term 2001. It was directed to graduated architecture students, who had to conceive and design a space-hotel with specific technical, economical and social requirements. The to be developed Space Hotel for a low earth orbit has to accommodate 220 guests. It was of utmost importance that this contest becomes an integral part of the student's tuition and that professors of the different academic and industrial institutions supported the project idea. During the summer term 2001 about fifty students occupied themselves with the topic, "design of an innovative space-hotel". The overall challenge was to create rooms used under microgravity environment, which means to overcome existing definitions and to find a new definition of living space. Because none of the students were able to experience such a room under microgravity they were forced to use the power of their imagination capability. The students attended moreover a number of lectures on different technical subjects focusing on space and went on several space-related excursions. Having specialists, as volunteers, in the field of space in charge meant that it could be ensured that the designs reflected a certain possibility of being able to be realized. Within the summer term seventeen major designs developed from the conceptual status to high sophisticated concepts and later on also to respective models. A competition combined with a public exhibition, that took place within the Annual German Aeronautics and Astronautics Congress, and intense media relations finalized this project. The project idea of "Early Bird - Visions of a Space Hotel" which was developed within six month is a remarkable example, how

    2003-01-01

    A detailed space suit computational model is being developed at the Langley Research Center for radiation exposure evaluation studies. The details of the construction of the space suit are critical to estimation of exposures and assessing the risk to the astronaut on EVA. Past evaluations of space suit shielding properties assumed the basic fabric layup (Thermal Micrometeoroid Garment, fabric restraints, and pressure envelope) and LCVG could be homogenized as a single layer overestimating the protective properties over 60 percent of the fabric area. The present space suit model represents the inhomogeneous distributions of LCVG materials (mainly the water filled cooling tubes). An experimental test is performed using a 34-MeV proton beam and high-resolution detectors to compare with model-predicted transmission factors. Some suggestions are made on possible improved construction methods to improve the space suit s protection properties.

  12. Dynamic modeling and adaptive control for space stations

    NASA Technical Reports Server (NTRS)

    Ih, C. H. C.; Wang, S. J.

    1985-01-01

    Of all large space structural systems, space stations present a unique challenge and requirement to advanced control technology. Their operations require control system stability over an extremely broad range of parameter changes and high level of disturbances. During shuttle docking the system mass may suddenly increase by more than 100% and during station assembly the mass may vary even more drastically. These coupled with the inherent dynamic model uncertainties associated with large space structural systems require highly sophisticated control systems that can grow as the stations evolve and cope with the uncertainties and time-varying elements to maintain the stability and pointing of the space stations. The aspects of space station operational properties are first examined, including configurations, dynamic models, shuttle docking contact dynamics, solar panel interaction, and load reduction to yield a set of system models and conditions. A model reference adaptive control algorithm along with the inner-loop plant augmentation design for controlling the space stations under severe operational conditions of shuttle docking, excessive model parameter errors, and model truncation are then investigated. The instability problem caused by the zero-frequency rigid body modes and a proposed solution using plant augmentation are addressed. Two sets of sufficient conditions which guarantee the globablly asymptotic stability for the space station systems are obtained.

    Wang, Hongyuan; Zhang, Wei; Dong, Aotuo

    2012-11-10

    A modeling and validation method of photometric characteristics of the space target was presented in order to track and identify different satellites effectively. The background radiation characteristics models of the target were built based on blackbody radiation theory. The geometry characteristics of the target were illustrated by the surface equations based on its body coordinate system. The material characteristics of the target surface were described by a bidirectional reflectance distribution function model, which considers the character of surface Gauss statistics and microscale self-shadow and is obtained by measurement and modeling in advance. The contributing surfaces of the target to observation system were determined by coordinate transformation according to the relative position of the space-based target, the background radiation sources, and the observation platform. Then a mathematical model on photometric characteristics of the space target was built by summing reflection components of all the surfaces. Photometric characteristics simulation of the space-based target was achieved according to its given geometrical dimensions, physical parameters, and orbital parameters. Experimental validation was made based on the scale model of the satellite. The calculated results fit well with the measured results, which indicates the modeling method of photometric characteristics of the space target is correct.

    2008-09-15

    This paper describes the development and initial demonstration of a new, integrated modeling and simulation framework, encompassing the space situational awareness enterprise, for quantitatively assessing the benefit of specific sensor systems, technologies and data analysis techniques. The framework is based on a flexible, scalable architecture to enable efficient, physics-based simulation of the current SSA enterprise, and to accommodate future advancements in SSA systems. In particular, the code is designed to take advantage of massively parallel computer systems available, for example, at Lawrence Livermore National Laboratory. The details of the modeling and simulation framework are described, including hydrodynamic models of satellite intercept and debris generation, orbital propagation algorithms, radar cross section calculations, optical brightness calculations, generic radar system models, generic optical system models, specific Space Surveillance Network models, object detection algorithms, orbit determination algorithms, and visualization tools. The use of this integrated simulation and modeling framework on a specific scenario involving space debris is demonstrated.

    1991-01-01

    Robots involved in high value manipulation must be effectively coupled to a human operator either at the work-site or remotely connected via communication links. In order to make use of experimental performance evaluation data, models must be developed. Powerful models of remote manipulation by humans can be used to predict manipulation performance in future systems based on today's laboratory systems. In this paradigm, the models are developed from experimental data, and then used to predict performance in slightly different situations. Second, accurate telemanipulation will allow design of manipulation systems which extend manipulation capability beyond its current bounds.

    2011-01-01

    One of NASA's missions is to attract and retain students in the science, technology, engineering and mathematics (STEM) disciplines. Creating missions or programs to achieve this important goal helps strengthen NASA and the nation's future work force as well as engage and inspire Americans and the rest of the world. During the last three years, in an attempt to revitalize educational space flight, NASA generated a new and exciting initiative. This initiative, NASA's Educational Launch of Nanosatellite (ELaNa), is now fully operational and producing exciting results. Nanosatellites are small secondary satellite payloads called CubeSats. One of the challenges that the CubeSat community faced over the past few years was the lack of rides into space. Students were building CubeSats but they just sat on the shelf until an opportunity arose. In some cases, these opportunities never developed and so the CubeSat never made it to orbit. The ELaNa initiative is changing this by providing sustainable launch opportunities for educational CubeSats. Across America, these CubeSats are currently being built by students in high school all the way through graduate school. Now students know that if they build their CubeSat, submit their proposal and are selected for an ELaNa mission, they will have the opportunity to fly their satellite. ELaNa missions are the first educational cargo to be carried on expendable launch vehicles (ELY) for NASA's Launch Services Program (LSP). The first ELaNa CubeSats were slated to begin their journey to orbit in February 2011 with NASA's Glory mission. Due to an anomaly with the launch vehicle, ELaNa II and Glory failed to reach orbit. This first ELaNa mission was comprised of three IU CubeSats built by students at Montana State University (Explorer Prime Flight 1), the University of Colorado (HERMES), and Kentucky Space, a consortium of state universities (KySat). The interface between the launch vehicle and the CubeSat, the Poly

    For sensitive detection of anomalous seismicity such as quiescence and activation in a given region, we need a suitable statistical reference model that represents a normal seismic activity in the region. The regional occurrence rate of the earthquakes is modeled as a function of previous activity, the specific form of which is based on empirical laws in time and space such as the modified Omori formula and the Utsu-Seki scaling law of aftershock area against magnitude, respectively. This manuscript summarizes the development of the epidemic type aftershock sequence (ETAS) model and proposes an extended version of the best fitted space-time model that was suggested in Ogata [Ogata, Y., 1998. Space-time point-process models for earthquake occurrences, Ann. Inst. Statist. Math., 50: 379-402.]. This model indicates significantly better fit to seismicity in various regions in and around Japan.

    For space to be truly commercialized, businesses of all sizes and types must be involved, from foundries to agricultural research initiatives. Achieving this goal, however, requires three separate but integrated educational efforts to support it. The first is to educate industry leaders about the possibilities available through such research, while dispelling some of the myths and misinformation educate the financial community about the economic benefits that result both from the research and the leveraging of private research dollars through the use of space and microgravity research. The third is to educate the public about the tangible benefits that come directly to them from such efforts, the economic benefits to national economies from same, and the other less tangible benefits that will cascade from commercial operations. Together, these steps will educate and provide the framework necessary to help advance space commercialization.

  3. Advanced Space Propulsion System Flowfield Modeling

    NASA Technical Reports Server (NTRS)

    Smith, Sheldon

    1998-01-01

    Solar thermal upper stage propulsion systems currently under development utilize small low chamber pressure/high area ratio nozzles. Consequently, the resulting flow in the nozzle is highly viscous, with the boundary layer flow comprising a significant fraction of the total nozzle flow area. Conventional uncoupled flow methods which treat the nozzle boundary layer and inviscid flowfield separately by combining the two calculations via the influence of the boundary layer displacement thickness on the inviscid flowfield are not accurate enough to adequately treat highly viscous nozzles. Navier Stokes models such as VNAP2 can treat these flowfields but cannot perform a vacuum plume expansion for applications where the exhaust plume produces induced environments on adjacent structures. This study is built upon recently developed artificial intelligence methods and user interface methodologies to couple the VNAP2 model for treating viscous nozzle flowfields with a vacuum plume flowfield model (RAMP2) that is currently a part of the Plume Environment Prediction (PEP) Model. This study integrated the VNAP2 code into the PEP model to produce an accurate, practical and user friendly tool for calculating highly viscous nozzle and exhaust plume flowfields.

  6. Connected-diagram expansions of effective Hamiltonians in incomplete model spaces. I. Quasicomplete and isolated incomplete model spaces

    NASA Astrophysics Data System (ADS)

    Kutzelnigg, Werner; Mukherjee, Debashis; Koch, Sigurd

    1987-11-01

    In this and the following paper, we formulate a Fock space theory for incomplete model spaces (IMS) that applies both to coupled-cluster expansions and to perturbation theory. We stress in this paper that the concept of the ``connected'' nature of extensive quantities like an effective Hamiltonian Heff is more fundamental than the ``linkedness'' that is conventionally used in many-body perturbation theory. The ``connectedness'' of Heff follows when the wave operator W is multiplicatively separable into noninteracting subsystems. This is ensured by writing W as an exponential Fock space operator with the exponent connected. It is demonstrated in particular that the connectedness of the exponent in W requires that the normalization condition of W be separable as well. Unlike the situation in a complete model space, the definition of ``diagonal'' or ``nondiagonal'' operators depends generally on the particular m-valence IMS. There are, however, special categories of IMS, the ``quasicomplete'' and the ``isolated'' model spaces, for which these definitions are possible without reference to the particular IMS. The formal properties of these IMS are discussed. It is shown that for the quasicomplete model space, the intermediate normalization is not separable, while it is so for the isolated model space.

  7. Space Radiation Dose Calculations for the Space Experiment Matroshka-R Modelling Conditions

    NASA Astrophysics Data System (ADS)

    Shurshakov, Vyacheslav; Kartashov, Dmitrij; Tolochek, Raisa

    Space radiation dose calculations for the space experiment Matroshka-R modelling conditions are presented in the report. The experiment has been carried out onboard the ISS from 2004 to 2014. Dose measurements were realized both outside the ISS on the outer surface of the Service Module with the MTR-facility and in the ISS compartments with anthropomorphic and spherical phantoms, and the protective curtain facility. Newly applied approach to calculate the shielding probability functions for complex shape objects is used when the object surface is composed from a set of the disjoint adjacent triangles that fully cover the surface. Using the simplified Matroshka-R shielding geometry models of the space station compartments the space ionizing radiation dose distributions in tissue-equivalent spherical and anthropomorphic phantoms, and for an additional shielding installed in the compartment are calculated. There is good agreement between the data obtained in the experiment and calculated ones within an experiment accuracy of about 10%. Thus the calculation method used has been successfully verified with the Matroshka-R experiment data. The suggested method can be recommended for modelling of radiation loads on the crewmembers, and estimation of the additional shielding efficiency in space station compartments, and also for pre-flight estimations of radiation shielding in future space missions.

  8. Radiation dosimetry and biophysical models of space radiation effects

    2003-01-01

    Estimating the biological risks from space radiation remains a difficult problem because of the many radiation types including protons, heavy ions, and secondary neutrons, and the absence of epidemiology data for these radiation types. Developing useful biophysical parameters or models that relate energy deposition by space particles to the probabilities of biological outcomes is a complex problem. Physical measurements of space radiation include the absorbed dose, dose equivalent, and linear energy transfer (LET) spectra. In contrast to conventional dosimetric methods, models of radiation track structure provide descriptions of energy deposition events in biomolecules, cells, or tissues, which can be used to develop biophysical models of radiation risks. In this paper, we address the biophysical description of heavy particle tracks in the context of the interpretation of both space radiation dosimetry and radiobiology data, which may provide insights into new approaches to these problems.

    Discrete state‐space models are used in ecology to describe the dynamics of wild animal populations, with parameters, such as the probability of survival, being of ecological interest. For a particular parametrization of a model it is not always clear which parameters can be estimated. This inability to estimate all parameters is known as parameter redundancy or a model is described as nonidentifiable. In this paper we develop methods that can be used to detect parameter redundancy in discrete state‐space models. An exhaustive summary is a combination of parameters that fully specify a model. To use general methods for detecting parameter redundancy a suitable exhaustive summary is required. This paper proposes two methods for the derivation of an exhaustive summary for discrete state‐space models using discrete analogues of methods for continuous state‐space models. We also demonstrate that combining multiple data sets, through the use of an integrated population model, may result in a model in which all parameters are estimable, even though models fitted to the separate data sets may be parameter redundant.

  16. A Modeler's Perspective on Space Weather Forecasting (Invited)

    NASA Astrophysics Data System (ADS)

    Wiltberger, M. J.

    2010-12-01

    Space physics is moving into a new era where numerical models originally developed for answering science questions are used as the basis for making operational space weather forecasts. Answering this challenge requires developments on multiple fronts requiring collaborations across space physics disciplines and between the research and operations communities. Since space weather in geospace is driven by the solar wind conditions a natural solution to improving the forecast lead time is to couple geospace models to heliospheric models. The quality of these forecast is dependent upon the ability of the heliospheric models to accurately model IMF Bz. Another challenge presented by moving into the forecasting arena is preparing the models for real-time operation which includes both computational performance and data redundancy issues. Moving into operations also presents modelers with an opportunity to assess their models performance over calculation intervals unprecedented duration. A key collaboration in the transition of models to operation is the discussion between forecasters and developers on what forecast parameters can accurately be predicted by the current generation of numerical models. This collaboration naturally includes a discussion of the definition of the best metrics to be used in quantitatively assessing performance.

    1993-01-01

    Regional air pollution, land-use conversion, and projected climate change all affect ecosystem processes at large scales. Changes in vegetation cover and growth dynamics can impact the functioning of ecosystems, carbon fluxes, and climate. As a result, there is a need to assess and monitor vegetation structure and function comprehensively at regional to global scales. To provide a test of our present understanding of how ecosystems operate at large scales we can compare model predictions of CO2, O2, and methane exchange with the atmosphere against regional measurements of interannual variation in the atmospheric concentration of these gases. Recent advances in remote sensing of the Earth's surface are beginning to provide methods for estimating important ecosystem variables at large scales. Ecologists attempting to generalize across landscapes have made extensive use of models and remote sensing technology. The success of such ventures is dependent on merging insights and expertise from two distinct fields. Ecologists must provide the understanding of how well models emulate important biological variables and their interactions; experts in remote sensing must provide the biophysical interpretation of complex optical reflectance and radar backscatter data.

    2015-04-01

    In 2005, a Dutch health insurer introduced a financial incentive directed to general practitioners to promote rational prescribing of statins and proton pump inhibitors (PPIs). Concomitantly, a regional institution that develops pharmacotherapeutic guidelines implemented two educational interventions also aiming at promoting rational statin and PPI prescribing. Utilizing a prescription database, we estimated the effect of the interventions on drug utilization and cost of statins and PPIs over time. We measured the effect of the interventions within an implementation and a control region. The implementation region included prescriptions from the province of Groningen where the educational intervention was implemented and where the health insurer is most active. The control region comprised all other provinces covered by the database. We modelled the effect of the intervention using a state-space approach. Significant differences in prescribing and cost patterns between regions were observed for statins and PPIs. These differences however were mostly related to the concurrent interventions of Proeftuin Farmacie Groningen. We found no evidence indicating a significant effect of the rational prescribing intervention on the prescription patterns of statins and PPIs. Our estimates on the economic impact of the Proeftuin Farmacie Groningen interventions indicate that educational activities as such can achieve significant cost savings.

    In this paper we report on state-space system identification approaches to dynamic behavioral abstraction of military simulation models. Two stochastic simulation models were identified under a variety of scenarios. The `Attrition Simulation' is a model of two opposing forces with multiple weapon system types. The `Mission Simulation' is a model of a squadron of aircraft performing battlefield air interdiction. Four system identification techniques: Maximum Entropy, Compartmental Models, Canonical State-Space Models, and Hidden Markov Models (HMM), were applied to these simulation models. The system identification techniques were evaluated on how well their resulting abstractions replicated the distributions of the simulation states as well as the decision outputs. Encouraging results were achieved by the HMM technique applied to the Attrition Simulation--and by the Maximum Entropy technique applied to the Mission Simulation.

    There are two space suits in current usage within the space program: EMU [2] and Orlan-M Space Suit . The Shuttle space suit components are discussed elsewhere [2,5,6] and serve as a guide to development of the current model. The present model is somewhat simplified in details which are considered to be second order in their effects on exposures. A more systematic approach is ongoing on a part-by-part basis with the most important ones in terms of exposure contributions being addressed first with detailed studies of the relatively thin space suit fabric as the first example . Additional studies to validate the model of the head coverings (bubble, helmet, visors.. .) will be undertaken in the near future. The purpose of this paper is to present the details of the model as it is now and to examine its impact on estimates of astronaut health risks. In this respect, the nonuniform distribution of mass of the space suit provides increased shielding in some directions and some organs. These effects can be most important in terms of health risks and especially critical to evaluation of potential early radiation effects .

    One of the major accompaniments of the globalization is the rapid growing of urban areas. Urban sprawl is the main environmental problem affecting those cities across different characteristics and continents. Various reasons for the increase in urban sprawl in the last 10 to 30 years have been proposed [1], and often depend on the socio-economic situation of cities. The quantitative reduction and the sustainable handling of land should be performed by inner urban development instead of expanding urban regions. Following the principal "spare the urban fringe, develop the inner suburbs first" requires differentiated tools allowing for quantitative and qualitative appraisals of current building potentials. Using spatial high resolution remote sensing data within an object-based approach enables the detection of potential areas while GIS-data provides information for the quantitative valuation. This paper presents techniques for modeling urban environment and opportunities of utilization of the retrieved information for urban planners and their special needs.

    The work performed during the first year 1 Oct. 1987 to 30 Sept. 1988 involved analyses of crystal growth from the melt and from solution. The particular melt growth technique under investigation is directional solidification by the Bridgman-Stockbarger method. Two types of solution growth systems are also being studied. One involves growth from solution in a closed container, the other concerns growth of protein crystals by the hanging drop method. Following discussions with Dr. R. J. Naumann of the Low Gravity Science Division at MSFC it was decided to tackle the analysis of crystal growth from the melt earlier than originally proposed. Rapid progress was made in this area. Work is on schedule and full calculations were underway for some time. Progress was also made in the formulation of the two solution growth models.

    1995-01-01

    Godunov-type numerical solution of the 20 moment plasma transport equations. One of the centerpieces of our proposal was the development of a higher order Godunov-type numerical scheme to solve the gyration dominated 20 moment transport equations. In the first step we explored some fundamental analytic properties of the 20 moment transport equations for a low b plasma, including the eigenvectors and eigenvalues of propagating disturbances. The eigenvalues correspond to wave speeds, while the eigenvectors characterize the transported physical quantities. In this paper we also explored the physically meaningful parameter range of the normalized heat flow components. In the second step a new Godunov scheme type numerical method was developed to solve the coupled set of 20 moment transport equations for a quasineutral single-ion plasma. The numerical method and the first results were presented at several national and international meetings and a paper describing the method has been published in the Journal of Computational Physics. To our knowledge this is the first numerical method which is capable of producing stable time-dependent solutions to the full 20 (or 16) moment set of transport equations, including the full heat flow equation. Previous attempts resulted in unstable (oscillating) solutions of the heat flow equations. Our group invested over two man-years into the development and implementation of the new method. The present model solves the 20 moment transport equations for an ion species and thermal electrons in 8 domain extending from a collision dominated to a collisionless region (200 km to 12,000 km). This model has been applied to study O+ acceleration due to Joule heating in the lower ionosphere.

    1980-01-01

    A deterministic model for monocular space perception is presented. According to the model, retinal luminance changes due to involuntary eye movements are detected and locally analyzed to yield the angular velocity of each image point. The stable three-dimensional spatial coordinates of viewed objects are then reconstructed using a method of infinitesimal transformations. The extraction of the movement (parallax) field from the optical flow is represented by a set of differential equations, the derivation of which is based on the conservation of energy principle. The relation of the model to retinal neurophysiology and to various aspects of visual space perception is discussed.

    The systems design process for future space transportation involves understanding multiple variables and their effect on lifecycle metrics. Variables such as technology readiness or potential environmental impact are qualitative, while variables such as reliability, operations costs or flight rates are quantitative. In deciding what new design concepts to fund, NASA needs a methodology that would assess the sum total of all relevant qualitative and quantitative lifecycle metrics resulting from each proposed concept. The objective of this research was to review the state of operations assessment methodologies and models used to evaluate proposed space transportation systems and to develop recommendations for improving them. It was found that, compared to the models available from other sources, the operations assessment methodology recently developed at Kennedy Space Center has the potential to produce a decision support tool that will serve as the industry standard. Towards that goal, a number of areas of improvement in the Kennedy Space Center's methodology are identified.

    The NASA Space Medicine program is now developing plans for more extensive use of high-fidelity medical simulation systems. The use of simulation is seen as means to more effectively use the limited time available for astronaut medical training. Training systems should be adaptable for use in a variety of training environments, including classrooms or laboratories, space vehicle mockups, analog environments, and in microgravity. Modeling and simulation can also provide the space medicine development program a mechanism for evaluation of other medical technologies under operationally realistic conditions. Systems and procedures need preflight verification with ground-based testing. Traditionally, component testing has been accomplished, but practical means for "human in the loop" verification of patient care systems have been lacking. Medical modeling and simulation technology offer potential means to accomplish such validation work. Initial considerations in the development of functional requirements and design standards for simulation systems for space medicine are discussed.

    Astronauts' radiation exposure limits are based on experimental and epidemiological data obtained on Earth. It is assumed that radiation sensitivity remains the same in the extraterrestrial space. However, human radiosensitivity is dependent upon the response of the hematopoietic tissue to the radiation insult. It is well known that the immune system is affected by microgravity. We have developed a mathematical model of radiation-induced myelopoiesis which includes the effect of microgravity on bone marrow kinetics. It is assumed that cellular radiosensitivity is not modified by the space environment, but repopulation rates of stem and stromal cells are reduced as a function of time in weightlessness. A realistic model of the space radiation environment, including the HZE component, is used to simulate the radiation damage. A dedicated computer code was written and applied to solar particle events and to the mission to Mars. The results suggest that altered myelopoiesis and lymphopoiesis in microgravity might increase human radiosensitivity in space. PMID:11771552

    Education during surgical residency has changed significantly. As part of the shifting landscape, the importance of an organized and structured curriculum has increased. However, establishing this is often difficult secondary to clinical demands and pressure both on faculty and residents. We present a peer-assisted learning model for academic institutions without professional non-clinical educations. The "resident as educator" (RAE) model empowers residents to be the organizers of the education curriculum. RAE is built on a culture of commitment to education, skill development and team building, allowing the upper level residents to develop and execute the curriculum. Several modules designed to address junior level residents and medical students' educational needs have been implemented, including (1) intern boot camp, (2) summer school, (3) technical skill sessions, (4) trauma orientation, (5) weekly teaching conferences, and (4) a fourth year medical student surgical preparation course. Promoting residents as educators leads to an overall benefit for the program by being cost-effective and time-efficient, while simultaneously promoting professional development of residents and a culture of education.

    Process modeling, the application of advanced computational techniques to simulate real processes as they occur in regular use, e.g., welding, casting and semiconductor crystal growth, is discussed. Using the low-gravity environment of space will accelerate the technical validation of the procedures and enable extremely accurate determinations of the many necessary thermophysical properties. Attention is given to NASA's centers for the commercial development of space; joint ventures of universities, industries, and goverment agencies to study the unique attributes of space that offer potential for applied R&D and eventual commercial exploitation.

    Prior to any human space flight, calculations of radiation risks are used to determine the acceptable scope of astronaut activity. Using the supercomputing facilities at NASA Ames Research Center, Ames researchers have determined the damage probabilities of DNA functional groups by space radiation. The data supercede those used in the current Monte Carlo model for risk assessment. One example is the reaction of DNA with hydroxyl radical produced by the interaction of highly energetic particles from space radiation with water molecules in the human body. This reaction is considered an important cause of DNA mutations, although its mechanism is not well understood.

    In this paper we develop a method capable of modeling the space-time focusing of nondiffracting pulses. These pulses can possess arbitrary peak velocities and, in addition to being resistant to diffraction, can have their peak intensities and focusing positions chosen a priori. More specifically, we can choose multiple locations (spatial ranges) of space and time focalization; also, the pulse intensities can be chosen in advance. The pulsed wave solutions presented here can have very interesting applications in many different fields, such as free-space optical communications, remote sensing, medical apparatus, etc.

    2006-01-01

    Earth based networking in support of various space agency projects has been based on leased service/circuits which has a high associated cost. This cost is almost always taken from the science side resulting in less science. This is a proposal to use Research and Education Networks (RENs) worldwide to support space flight operations in general and space-based science operations in particular. The RENs were developed to support scientific and educational endeavors. They do not provide support for general Internet traffic. The connectivity and performance of the research and education networks is superb. The connectivity at Layer 3 (IP) virtually encompasses the globe. Most third world countries and all developed countries have their own research and education networks, which are connected globally. Performance of the RENs especially in the developed countries is exceptional. Bandwidth capacity currently exists and future expansion promises that this capacity will continue. REN performance statistics has always exceeded minimum requirements for spaceflight support. Research and Education networks are more loosely managed than a corporate network but are highly managed when compared to the commodity Internet. Management of RENs on an international level is accomplished by the International Network Operations Center at Indiana University at Indianapolis. With few exceptions, each regional and national REN has its own network ops center. The acceptable use policies (AUP), although differing by country, allows any scientific program or project the use of their networks. Once in compliance with the first RENs AUP, all others will accept that specific traffic including regional and transoceanic networks. RENs can support spaceflight related scientific programs and projects. Getting the science to the researcher is obviously key to any scientific project. RENs provide a pathway to virtually any college or university in the world, as well as many governmental institutes and

    Spatial-temporal data requires flexible regression models which can model the dependence of responses on space- and time-dependent covariates. In this paper, we describe a semiparametric space-time model from a Bayesian perspective. Nonlinear time dependence of covariates and the interactions among the covariates are constructed by local linear and piecewise linear models, allowing for more flexible orientation and position of the covariate plane by using time-varying basis functions. Space-varying covariate linkage coefficients are also incorporated to allow for the variation of space structures across the geographical location. The formulation accommodates uncertainty in the number and locations of the piecewise basis functions to characterize the global effects, spatially structured and unstructured random effects in relation to covariates. The proposed approach relies on variable selection-type mixture priors for uncertainty in the number and locations of basis functions and in the space-varying linkage coefficients. A simulation example is presented to evaluate the performance of the proposed approach with the competing models. A real data example is used for illustration.

  17. Modeling Coastal Vulnerability through Space and Time

    PubMed Central

    2016-01-01

    Coastal ecosystems experience a wide range of stressors including wave forces, storm surge, sea-level rise, and anthropogenic modification and are thus vulnerable to erosion. Urban coastal ecosystems are especially important due to the large populations these limited ecosystems serve. However, few studies have addressed the issue of urban coastal vulnerability at the landscape scale with spatial data that are finely resolved. The purpose of this study was to model and map coastal vulnerability and the role of natural habitats in reducing vulnerability in Jamaica Bay, New York, in terms of nine coastal vulnerability metrics (relief, wave exposure, geomorphology, natural habitats, exposure, exposure with no habitat, habitat role, erodible shoreline, and surge) under past (1609), current (2015), and future (2080) scenarios using InVEST 3.2.0. We analyzed vulnerability results both spatially and across all time periods, by stakeholder (ownership) and by distance to damage from Hurricane Sandy. We found significant differences in vulnerability metrics between past, current and future scenarios for all nine metrics except relief and wave exposure. The marsh islands in the center of the bay are currently vulnerable. In the future, these islands will likely be inundated, placing additional areas of the shoreline increasingly at risk. Significant differences in vulnerability exist between stakeholders; the Breezy Point Cooperative and Gateway National Recreation Area had the largest erodible shoreline segments. Significant correlations exist for all vulnerability (exposure/surge) and storm damage combinations except for exposure and distance to artificial debris. Coastal protective features, ranging from storm surge barriers and levees to natural features (e.g. wetlands), have been promoted to decrease future flood risk to communities in coastal areas around the world. Our methods of combining coastal vulnerability results with additional data and across multiple time

    NASA is eager for students and the public to experience lunar Apollo rocks and regolith soils first hand. Lunar samples embedded in plastic are available for educators to use in their classrooms, museums, science centers, and public libraries for education activities and display. The sample education disks are valuable tools for engaging students in the exploration of the Solar System. Scientific research conducted on the Apollo rocks has revealed the early history of our Earth-Moon system. The rocks help educators make the connections to this ancient history of our planet as well as connections to the basic lunar surface processes - impact and volcanism. With these samples educators in museums, science centers, libraries, and classrooms can help students and the public understand the key questions pursued by missions to Moon. The Office of the Curator at Johnson Space Center is in the process of reorganizing and renewing the Lunar and Meteorite Sample Education Disk Program to increase reach, security and accountability. The new program expands the reach of these exciting extraterrestrial rocks through increased access to training and educator borrowing. One of the expanded opportunities is that trained certified educators from science centers, museums, and libraries may now borrow the extraterrestrial rock samples. Previously the loan program was only open to classroom educators so the expansion will increase the public access to the samples and allow educators to make the critical connections of the rocks to the exciting exploration missions taking place in our solar system. Each Lunar Disk contains three lunar rocks and three regolith soils embedded in Lucite. The anorthosite sample is a part of the magma ocean formed on the surface of Moon in the early melting period, the basalt is part of the extensive lunar mare lava flows, and the breccias sample is an important example of the violent impact history of the Moon. The disks also include two regolith soils and

    The development and testing of a mouse model for simulating some aspects of weightlessness that occur during space flight, and the carrying out of immunological flight experiments on animals was discussed. The mouse model is an antiorthostatic, hypokinetic, hypodynamic suspension model similar to the one used with rats. It is shown that this murine model yield similar results to the rat model of antiorthostatic suspension for simulating some aspects of weightlessness. It is also shown that mice suspended in this model have decreased interferon-alpha/beta production as compared to control, nonsuspended mice or to orthostatically suspended mice. It is suggested that the conditions occuring during space flight could possibly affect interferon production. The regulatory role of interferon in nonviral diseases is demonstrated including several bacterial and protozoan infections indicating the great significance of interferon in resistance to many types of infectious diseases.

    The processes influencing animal movement and resource selection are complex and varied. Past efforts to model behavioral changes over time used Bayesian statistical models with variable parameter space, such as reversible-jump Markov chain Monte Carlo approaches, which are computationally demanding and inaccessible to many practitioners. We present a continuous-time discrete-space (CTDS) model of animal movement that can be fit using standard generalized linear modeling (GLM) methods. This CTDS approach allows for the joint modeling of location-based as well as directional drivers of movement. Changing behavior over time is modeled using a varying-coefficient framework which maintains the computational simplicity of a GLM approach, and variable selection is accomplished using a group lasso penalty. We apply our approach to a study of two mountain lions (Puma concolor) in Colorado, USA.

    The International Space Station (ISS) National Lab Education Project has been created as a part of the ISS National Lab effort mandated by the U.S. Congress The project seeks to expand ISS education of activities so that they reach a larger number of students with clear educational metrics of accomplishments. This paper provides an overview of several recent ISS educational payloads and activities. The expected outcomes of the project, consistent with those of the NASA Office of Education, are also described. NASA performs numerous education activities as part of its ISS program. These cover the gamut from formal to informal educational opportunities in grades Kindergarten to grade 12, Higher Education (undergraduate and graduate University) and informal educational venues (museums, science centers, exhibits). Projects within the portfolio consist of experiments performed onboard the ISS using onboard resources which require no upmass, payloads flown to ISS or integrated into ISS cargo vehicles, and ground based activities that follow or complement onboard activities. Examples include ground based control group experiments, flight or experiment following lesson plans, ground based activities involving direct interaction with ISS or ground based activities considering ISS resources in their solution set. These projects range from totally NASA funded to projects which partner with external entities. These external agencies can be: other federal, state or local government agencies, commercial entities, universities, professional organizations or non-profit organizations. This paper will describe the recent ISS education activities and discuss the approach, outcomes and metrics associated with the projects.

It is a scientifically-based information show with visitors involvement, its elements being partially virtual (Earth in space has to be projected with highest possible resolution) but also containing real structures, such as the visitors' Earth observatory with adjacent biological systems (plant cultures and other ecological life support components). Its main message concerns the limits and the vulnerability of our home planet, its uniqueness, beauty and above all, its irreplaceableness: Earth does not have an emergency exit. The Earth observatory is part of a ring shaped, rotating space station of the type designed by Wernher von Braun decades ago. Visitors are told that gravity is being substituted by centrifugal force. Both types of life support systems are being demonstrated--self regenerative life based ones and technical ones as a backup (solar electric splitting of water and chemical absorption of respiratory CO2).

  10. Planetarium Inversum -- a space vision for Earth education.

    PubMed

    Lotsch, B

    2003-01-01

    In a planetarium, the visitor is sitting on Earth and looking into an imaginary space. The Planetarium Inversum is the opposite: visitors are sitting in a space station, looking down on Mother Earth. It is a scientifically-based information show with visitors involvement, its elements being partially virtual (Earth in space has to be projected with highest possible resolution) but also containing real structures, such as the visitors' Earth observatory with adjacent biological systems (plant cultures and other ecological life support components). Its main message concerns the limits and the vulnerability of our home planet, its uniqueness, beauty and above all, its irreplaceableness: Earth does not have an emergency exit. The Earth observatory is part of a ring shaped, rotating space station of the type designed by Wernher von Braun decades ago. Visitors are told that gravity is being substituted by centrifugal force. Both types of life support systems are being demonstrated--self regenerative life based ones and technical ones as a backup (solar electric splitting of water and chemical absorption of respiratory CO2).

    2016-07-01

    In accordance with the resolution of ISO TC20/SC14 WG4/WG6 joint meeting, Technical Specification (TS) 'Modeling of space environment impact on nanostructured materials. General principles' which describes computer simulation methods of space environment impact on nanostructured materials is being prepared. Nanomaterials surpass traditional materials for space applications in many aspects due to their unique properties associated with nanoscale size of their constituents. This superiority in mechanical, thermal, electrical and optical properties will evidently inspire a wide range of applications in the next generation spacecraft intended for the long-term (~15-20 years) operation in near-Earth orbits and the automatic and manned interplanetary missions. Currently, ISO activity on developing standards concerning different issues of nanomaterials manufacturing and applications is high enough. Most such standards are related to production and characterization of nanostructures, however there is no ISO documents concerning nanomaterials behavior in different environmental conditions, including the space environment. The given TS deals with the peculiarities of the space environment impact on nanostructured materials (i.e. materials with structured objects which size in at least one dimension lies within 1-100 nm). The basic purpose of the document is the general description of the methodology of applying computer simulation methods which relate to different space and time scale to modeling processes occurring in nanostructured materials under the space environment impact. This document will emphasize the necessity of applying multiscale simulation approach and present the recommendations for the choice of the most appropriate methods (or a group of methods) for computer modeling of various processes that can occur in nanostructured materials under the influence of different space environment components. In addition, TS includes the description of possible

    STERN, the German word for star, is also an acronym for STudentische Experimental-RaketeN. It is a program to provide students with “hands-on” experience in space systems and research. This name was chosen for two reasons. The first reason was to emphasize the idealistic goals of spaceflight providing students with the opportunity to “reach for the stars”. The second and most important one was that the program offers engineering students a practical chance to experience the scope of aerospace and should motivate them to become a new star in this field. Currently eight German universities are participating in the STERN-program. STERN was initiated in April 2012, by the DLR Space Administration in Bonn and is supported by funds from the German Federal Ministry of Economics and Technology (BMWi). During the project runtime of three years the students should develop and launch their own rocket. There are no limits regarding trajectory, altitude or the propulsion system used (solid fuel, liquid fuel, steam or hybrid). The reason for the “no limits” strategy is to create a new perspective of a problem and encourage new technological ideas. The students shall not be limited in their creativity. Nevertheless the spacecraft should have a telemetry system to transmit key trajectory and housekeeping data back to earth during flight and provide information to the students including the rocket altitude. Moreover the rocket shall reach a velocity of at least Mach 1 . The project requirements are set to show the real world of work to the students. To reach the project goal, the students have to work project-oriented and in teams. In order to teach students engineering and science, as well as to put their technical knowledge to the test as early as possible in their studies, they are integrated into courses at their universities, which already deal with various aspects of rocket technology and space research. As in any development program, the students have to pass

  13. Combustion modeling for experimentation in a space environment

    NASA Technical Reports Server (NTRS)

    Berlad, A. L.

    1974-01-01

    The merits of combustion experimentation in a space environment are assessed, and the impact of such experimentation on current theoretical models is considered. It is noted that combustion theory and experimentation for less than normal gravitational conditions are incomplete, inadequate, or nonexistent. Extensive and systematic experimentation in a space environment is viewed as essential for more adequate and complete theoretical models of such processes as premixed flame propagation and extinction limits, premixed flame propagation in droplet and particle clouds, ignition and autoignition in premixed combustible media, and gas jet combustion of unpremixed reactants. Current theories and models in these areas are described, and some combustion studies that can be undertaken in the Space Shuttle Program are proposed, including crossed molecular beam, turbulence, and upper pressure limit (of gases) studies.

  7. Young engineers and scientists - a mentorship program emphasizing space education

    NASA Astrophysics Data System (ADS)

    Boice, Daniel; Asbell, Elaine; Reiff, Patricia

    Young Engineers and Scientists (YES) is a community partnership between Southwest Research Institute (SwRI), and local high schools in San Antonio, Texas (USA) during the past 16 years. The YES program provides talented high school juniors and seniors a bridge between classroom instruction and real world, research experiences in physical sciences (including space science) and engineering. The first component of YES is an intensive three-week summer workshop held at SwRI where students experience the research environment first-hand; develop skills and acquire tools for solving scientific problems, attend mini-courses and seminars on electronics, computers and the Internet, careers, science ethics, and other topics; and select individual research projects to be completed during the academic year. Afterwards, students complete individual research projects under the guidance of their mentors during the academic year and earn honors credit. At the end of the school year, students publicly present and display their work, acknowledging their accomplishments and spreading career awareness to other students and teachers. During these years, YES has developed a website for topics in space science from the perspective of high school students, including NASA's Magnetospheric Multiscale Mission (MMS) (http://yesserver.space.swri.edu). High school science teachers participate in the workshop and develop space-related lessons for classroom presentation in the academic year. Student evaluations indicate the effectiveness of YES on their academic preparation and choice of college majors. Over the past 16 years, all YES graduates have entered college, several have worked for SwRI, one business has started, and three scientific publications have resulted. Acknowledgements. We acknowledge funding and support from the NASA MMS Mission, Texas Space Grant Consortium, Northside Independent School District, SwRI, and several local charitable foundations.

    We explore the phase structure of nonlinear sigma models with target spaces corresponding to compact quotients of hyperbolic space, focusing on the case of a hyperbolic genus-2 Riemann surface. The continuum theory of these models can be approximated by a lattice spin system which we simulate using Monte Carlo methods. The target space possesses interesting geometric and topological properties which are reflected in novel features of the sigma model. In particular, we observe a topological phase transition at a critical temperature, above which vortices proliferate, reminiscent of the Kosterlitz-Thouless phase transition in the O(2) model [1, 2]. Unlike in themore » O(2) case, there are many different types of vortices, suggesting a possible analogy to the Hagedorn treatment of statistical mechanics of a proliferating number of hadron species.

  11. Weight and the Future of Space Flight Hardware Cost Modeling

    NASA Technical Reports Server (NTRS)

    Prince, Frank A.

    2003-01-01

    Weight has been used as the primary input variable for cost estimating almost as long as there have been parametric cost models. While there are good reasons for using weight, serious limitations exist. These limitations have been addressed by multi-variable equations and trend analysis in models such as NAFCOM, PRICE, and SEER; however, these models have not be able to address the significant time lags that can occur between the development of similar space flight hardware systems. These time lags make the cost analyst's job difficult because insufficient data exists to perform trend analysis, and the current set of parametric models are not well suited to accommodating process improvements in space flight hardware design, development, build and test. As a result, people of good faith can have serious disagreement over the cost for new systems. To address these shortcomings, new cost modeling approaches are needed. The most promising approach is process based (sometimes called activity) costing. Developing process based models will require a detailed understanding of the functions required to produce space flight hardware combined with innovative approaches to estimating the necessary resources. Particularly challenging will be the lack of data at the process level. One method for developing a model is to combine notional algorithms with a discrete event simulation and model changes to the total cost as perturbations to the program are introduced. Despite these challenges, the potential benefits are such that efforts should be focused on developing process based cost models.

  12. A medical model for criminalistics education.

    1988-07-01

    The history of medical education during the period of 1870 to 1926 is examined in the context of current issues confronting education in the forensic laboratory sciences. Medical education was radically altered during this period, changing from a rudimentary lecture/apprenticeship system into its modern form. Although the motivating forces had developed over some time, the actual change was quite rapid. By examining how this change occurred, we gain insight into how changes in our own profession might be initiated. Parallels between our current situation and that in medical education 117 years ago include: (1) the primary burden of professional education is borne outside the university in an apprenticeship system, (2) the apprenticeship system is overburdened by a dramatic expansion in the knowledge and skills needed for professional practice, (3) there is no standardized curriculum or accreditation process for educational programs, and (4) there is no educational program that incorporates formal clinical education. Based on this historical analysis, three major goals are proposed: (1) active entreprenurial promotion of professional educational programs by academics, (2) creation of a committee within the American Academy of Forensic Sciences to critique and rate university programs, and (3) the development of a well-defined clinical education program. A model for formalized clinical education in the forensic laboratory sciences is proposed, incorporating clinical professors, student clerkships, and university control over instruction within an operational forensic science laboratory. Benefits from this arrangement include: efficient combination of physical plants, added personnel resources in the laboratory, rapid introduction of research into the laboratory, enhanced prestige for both academics and practitioners, and relief of the laboratory's in-house training burden.

    Medical and nursing student numbers are expected to increase significantly in NZ over the next few years. The ethical, and professional and clinical skills' training of trainee health practitioners is a central and crucial component in medical and nursing education and is underpinned by a strong commitment to improve patient health and well being. In this discussion we reflect on the virtue of empathy and the importance of role modelling in the education of nurses and doctors. We endorse the claim that as medical educators, how and what we teach matters.

    Amateur Radio on the International Space Station (ARISS) represents the first educational outreach program that is flying on the International Space Station (ISS). The astronauts and cosmonauts will work hard on the International Space Station, but they plan to take some time off for educational activities with schools. The National Aeronautics and Space Administration s (NASA s) Education Division is a major supporter and sponsor of this student outreach activity on the ISS. This meets NASA s educational mission objective: To inspire the next generation of explorers.. .as only NASA can. The amateur radio community is helping to enrich the experience of those visiting and living on the station as well as the students on Earth. Through ARISS sponsored hardware and activities, students on Earth get a first-hand feel of what it is like to live and work in space. This paper will discuss the educational outreach accomplishments of ARISS, the school contact process, the ARISS international cooperation and volunteers, and ISS Ham radio plans for the future.

    2011-07-01

    We present a general analytical model for periodic chains of elastically coupled particles subject to thermal noise and quenched disorder. Our model estimates the variance in particle spacing in the long-time limit as a function of the strength of disorder and the deterministic coupling. We apply our theory to experimental results from magnetic cross tie domain wall studies. We extract a measure of the vortex-vortex interaction in the cross tie wall and relate this to the mean and variance in vortex-vortex spacing for a cross tie wall.

    Packet switched data communications networks that use distributed processing architectures have the potential to simplify the design and development of new, increasingly more sophisticated satellite payloads. In addition, the use of reconfigurable logic may reduce the amount of redundant hardware required in space-based applications without sacrificing reliability. These concepts were studied using software modeling and simulation, and the results are presented in this report. Models of the commercially available, packet switched data interconnect SpaceWire protocol were developed and used to create network simulations of data networks containing reconfigurable logic with traffic flows for timing system distribution.

    1991-01-01

    The use of animal surrogates as experimental subjects in order to provide essential missing information on the effects of long-term spaceflights, to validate countermeasures, and to test medical treatment techniques is discussed. Research needs also include the definition of biomedical adaptations to flight, and the developments of standards for safe space missions to assure human health and productivity during and following flight. NASA research plans in this area are outlined. Over the next 40 years, NASA plans to concentrate on the use of rodents and nonhuman primates as the models of choice for various physiological responses observed in humans during extended stays in space. This research will include flights on the Space Shuttle, unmanned biosatellites, and the Space Station Freedom.

  20. Parameter space for a dissipative Fermi-Ulam model

    NASA Astrophysics Data System (ADS)

    Oliveira, Diego F. M.; Leonel, Edson D.

    2011-12-01

    The parameter space for a dissipative bouncing ball model under the effect of inelastic collisions is studied. The system is described using a two-dimensional nonlinear area-contracting map. The introduction of dissipation destroys the mixed structure of phase space of the non-dissipative case, leading to the existence of a chaotic attractor and attracting fixed points, which may coexist for certain ranges of control parameters. We have computed the average velocity for the parameter space and made a connection with the parameter space based on the maximum Lyapunov exponent. For both cases, we found an infinite family of self-similar structures of shrimp shape, which correspond to the periodic attractors embedded in a large region that corresponds to the chaotic motion.
