    Community Coordinated Modeling Center (CCMC) has developed over the years a comprehensive set of tools that are directly applicable to higher education. The tools range from standard runs-on-request system providing access to state-of-the-art solar and space physics models to online tutorials on space weather analysis. CCMC has also supported directly, for example, by means of tailored simulations and web interfaces various educational activities such as CISM and Heliophysics Summer Schools. In this paper we provide a brief overview of CCMC tools that can benefit a variety of educational efforts. We will discuss, for example, the usage of integrated Space Weather Analysis (iSWA) system, CCMC runs-on-request system, advanced visualizations tools such as Space Weather Explorer 2 and other publicly available CCMC material in higher education. We will give explicit examples of some of our success stories and outline our envisioned higher education path forward. The main portals to CCMC's educational material are ccmc.gsfc.nasa.gov and iswa.gsfc.nasa.gov.

    1995-01-01

    The goal of this Space Physics Educational Outreach project was to develop a laboratory experiment and classroom lecture on Earth's aurora for use in lower division college physics courses, with the particular aim of implementing the experiment and lecture at Saint Mary's College of California. The strategy is to teach physics in the context of an interesting natural phenomenon by investigating the physical principles that are important in Earth's aurora, including motion of charged particles in electric and magnetic fields, particle collisions and chemical reactions, and atomic and molecular spectroscopy. As a by-product, the undergraduate students would develop an appreciation for naturally occurring space physics phenomena.

    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.

    2008-12-01

    Informal science education institutions, such as science centers, play an important role in science education. They serve millions of people, including students and teachers. Within the last decade, many have tried to improve the public's understanding of science and scientific research through informal education projects. The recent success of several space weather-related missions and research programs and the launch of the International Heliophysical Year (IHY) research and education programs make this an ideal time to inform the public about the importance and relevance of space weather to our understanding of heliophysical science. Communication efforts associated with space weather both benefit and are compromised by analogies to terrestrial weather. This paper summarizes the benefits and challenges of the terrestrial weather analogy using two exhibit evaluation studies. The paper also describes three components of the Space Science Institute's Space Weather Outreach Program: Space Weather Center Website, Educator Workshops, and Small Exhibits for Libraries and Science Centers.

It also includes introductory online course material that the participants can study at their leisure. The first session is held at the TUD, with subsequent sessions held at strategic space agency locations. By participating at two or more of these sessions, attendees can earn certificates of satisfactory completion from TU Delft. By participating in all of the sessions, as well as taking part in the companion Central Case Project (CCP), participants earn an accredited and highly respected master's degree in Space Systems Engineering from the TUD. Seven distinct SpaceTech modules are provided during these sessions: Space Mission Analysis and Design, Systems Engineering, Business Engineering, Interpersonal Skills, Telecommunications, Earth Observation and Navigation. A group CCP, a major asset of this unique program, is a focused project, aimed at the formation of a credible virtual commercial space-related business. Participants exercise space systems engineering fundamentals as well as marketing and business engineering tools, with the goal of creating a financially viable business opportunity. They then present the result, in the form of an unsolicited proposal to potential investors, as well as a varied group of engineers, managers and executives from the space community. During the CCP, participants learn the ties between mission and system design and the potential return to investors. They develop an instinct for the technical concepts and which of the parameters to adjust to make their newly conceived business more effective and profitable.

    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.

    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.

    Cleveland, Benjamin; Kvan, Thomas

    2015-07-01

    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 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.

    2009-12-01

    Surveys and focus groups suggest that science education faculty and other science faculty who help prepare future teachers can benefit greatly from each other through professional development incorporating educationally-researched pedagogical techniques, the latest Earth and space science discoveries, materials, and new activities. In response, a team of scientists and science educators has delivered four such 2-day faculty institutes, through our Faculty Institute for NASA Earth and Space Science Education (FINESSE). One challenge to inquiry is the time spent obtaining true data, and yet the majority of astronomers and planetary scientists are using existing data acquired by robotic missions, telescopes, and orbiters. Through these workshops, participating College of Science and College of Education faculty have co-developed mechanisms for working inquiry into a deeper understanding of science by using existing on-line data to develop and research Earth and space science topics, progressing from creating a valid and easily testable question, to simple data analysis, arriving at a conclusion, and finally presenting and supporting that conclusion in the classroom. This framework is the foundation of the FINESSE institutes, which also incorporate discussions on the nature of inquiry, assessment, presentations by Earth and space science researchers, and opportunities for the participants to design implementation plans of their own. This project was developed to help faculty overcome several roadblocks, including: many education faculty surveyed stated that they desired, but lacked, access to professional development experiences; education faculty responsible for training pre-service education students varied greatly in their own science experiences and level of expertise, with a majority having a science background in biology but little or no experience in Earth or space science; the modeling of best science education practices (e.g., building understanding through authentic inquiry, use of real data, connections to educational research, alignment with standards, etc.) in methods classes also varied greatly, as did the education faculty’s awareness and training in the use of appropriate Earth and space science resources; and that science faculty often have the content expertise, but rarely model teaching practices that are needed by classroom teachers, making it more challenging for pre-service students to translate science into their future classrooms.

  5. Space station contamination modeling

    NASA Technical Reports Server (NTRS)

    Gordon, T. D.

    1989-01-01

    Current plans for the operation of Space Station Freedom allow the orbit to decay to approximately an altitude of 200 km before reboosting to approximately 450 km. The Space Station will encounter dramatically increasing ambient and induced environmental effects as the orbit decays. Unfortunately, Shuttle docking, which has been of concern as a high contamination period, will likely occur during the time when the station is in the lowest orbit. The combination of ambient and induced environments along with the presence of the docked Shuttle could cause very severe contamination conditions at the lower orbital altitudes prior to Space Station reboost. The purpose here is to determine the effects on the induced external environment of Space Station Freedom with regard to the proposed changes in altitude. The change in the induced environment will be manifest in several parameters. The ambient density buildup in front of ram facing surfaces will change. The source of such contaminants can be outgassing/offgassing surfaces, leakage from the pressurized modules or experiments, purposeful venting, and thruster firings. The third induced environment parameter with altitude dependence is the glow. In order to determine the altitude dependence of the induced environment parameters, researchers used the integrated Spacecraft Environment Model (ISEM) which was developed for Marshall Space Flight Center. The analysis required numerous ISEM runs. The assumptions and limitations for the ISEM runs are described.

  6. Educational Outreach: The Space Science Road Show

    NASA Astrophysics Data System (ADS)

    Cox, N. L. J.

    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 community thought. The difficulty with a show this elaborate and intricate is communicating on a level understandable for teenagers, whilst not treating them like children. Professional space scientists know how easy it is to lose oneself in technical specifics. This would, of course, only confuse young people. The author would like to discuss the ideas for this show with a knowledgeable audience and hopefully get some (constructive) feedback.

    Parametric cost models are an important tool for planning missions, compare concepts and justify technology investments. This paper presents on-going efforts to develop single variable and multi-variable cost models for space telescope optical telescope assembly (OTA). These models are based on data collected from historical space telescope missions. Standard statistical methods are used to derive CERs for OTA cost versus aperture diameter and mass. The results are compared with previously published models.

    Background Spaced education (SE) has shown promise as an instructional tool that uses repeated exposure to the same questions, but information on its utility in graduate medical education is limited, particularly in assessing knowledge gain with outcome measures that are different from repeat exposure to the intervention questions. Objective We examined whether SE is an effective instructional tool for pediatrics residents learning dermatology using an outcome measure that included both unique and isomorphic questions. Methods We randomized 81 pediatrics residents into 2 groups. Group A completed an SE course on atopic dermatitis and warts and molluscum. Group B completed an SE course on acne and melanocytic nevi. Each course consisted of 24 validated SE items (question, answer, and explanation) delivered 2 at a time in 2 e-mails per week. Both groups completed a pretest and posttest on all 4 topics. Each group served as the comparison for the other group. Results Fifty residents (60%) completed the study. The course did not have a statistically significant effect on the posttest scores for either group. Overall, test scores were low. Eighty-eight percent of residents indicated that they would like to participate in future SE courses. Conclusions Using primarily novel posttest questions, this study did not demonstrate the significant knowledge gains that other investigators have found with SE. PMID:24949130

    The Brazilian Space Agency (AEB) sponsors an outreach program aimed at promoting Brazilian space activities among students and teachers of primary and secondary schools. The program, called AEB Escola (Brazilian Space Agency School), was created in 2003 and, since then, has taken the space theme to thousands of students and teachers. The main goal of the AEB Escola Program is to make the Brazilian Space Program known among students and teachers. Additionally, it intends to use the space theme as a way to increase youth interest in studies in general, and in sciences in particular. The program focuses on teachers who, ultimately, are the ones responsible for introducing the subject to their students. And who also guarantee the continuity of the Program. An Astronautics and Space Science course is given to teachers by researchers involved with the Brazilian Space Program activities. The course has over 100 h of activities covering the following themes: Astronomy, Satellite Launcher Vehicles, Satellites and Space Platforms, Remote Sensing, Meteorology and Environmental Sciences, and Projects's Learning. The AEB Escola Program also promotes many other activities among students including lectures, contests, interactive exhibitions and hands-on activities. One of the consequences of such initiatives was the creation of two experiments taken to the International Space Station in April 2006 by the Brazilian astronaut, Marcos Pontes. Moreover, a nationwide contest called Brazilian Astronomy and Astronautical Olympics (OBA) is held every year involving nearly half a million students, with ages ranging from 7 to 17. The top five students are taken to the International Astronomy Olympics, where Brazil has obtained many medals. The top 50 students of OBA are taken, along with their teachers, to the city of Săo José dos Campos, in the state of Săo Paulo, to participate in the Space Journey event. The journey lasts a week during which the participants get a chance to learn about the activities and infrastructure of the National Institute of Space Research (INPE) and the Institute of Aeronautics and Space (IAE), the leading Brazilian institutions linked to Space activities. The material used by the teachers is produced by a net of partners, including universities and the Brazilian Ministry of Education. The material is produced both in printed and electronics format: CDs and DVDs, being distributed, free of charge, to thousands of schools. The paper introduces the concepts, methods, achievements and perspectives of the AEB Escola Program.

    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 science. The boundary sectioning area of effective and unefficient modes of training and education of the population of country in space spirit is determined. The mathematical model of quality of process of education concern to an outer space exploration is reviewed separately. The coefficient of quality of education in an estimation of space event is submitted as relation ? I' to mismatch of the universal standard of behavior with the information, which is going to the external spectator, about the applicable reacting of the considered individual ? I''. The obtained outcomes allow to control a learning process and education of the society spirit of adherence to space ideals of mankind.

    It's a challenge educators at all grade levels face: How do you teach subjects your students can't see, touch, or hear? You do it with models--which have gained new importance since the National Science Education Standards specifically recommended using models as an organizing framework for teaching and understanding science. Whether your lessons concern molecules or Mars, Understanding Models in Earth and Space Science offers practical guidance. It's designed to help you understand the full range of models available to illustrate abstract concepts, demonstrate complex ideas, or teach about things students can't see. The book provides an in-depth look at specific kinds of models--what they are, how they can be designed, the best ways to use them, and possible shortcomings. Among the chapter topics are concrete models; mathematical models; similes, analogies, and metaphors; computer models; and inquiry and model building. Itself a model of good modeling, the book offers abundant examples (including drawing parallels between seemingly unrelated topics, such as how tornadoes are like vacuum cleaners) and plentiful background specific to Earth science teachers. Understanding Models is the result of a partnership between NSTA and the U.S. Environmental Protection Agency's Office of Pollution Prevention and Toxics.

    There has been a renaissance of interest in space radiation environment modeling. This has been fueled by the growing need to replace long time standard AP-9 and AE-8 trapped particle models, the interplanetary exploration initiative, the modern satellite instrumentation that has led to unprecedented measurement accuracy, and the pervasive use of Commercial off the Shelf (COTS) microelectronics that require more accurate predictive capabilities. The objective of this viewgraph presentation was to provide basic understanding of the components of the space radiation environment and their variations, review traditional radiation effects application models, and present recent developments.

  19. A river model of space

    Braeck, Simen; Grřn, Řyvind

    2013-02-01

    We expand on Hamilton and Lisle's idea of a river model of black holes (Am. J. Phys. 76, 519 (2008)) by presenting a reformulation of the river description in terms of an orthonormal basis field attached to static observers and then apply it to the Schwarzschild-de Sitter, the Schwarzschild and the de Sitter spacetimes. The physical space is defined as a specified set of freely moving reference particles. Using a combination of orthonormal basis fields and the usual formalism in a coordinate basis we calculate the physical velocity field of these reference particles. In this way one obtains a vivid description of space in which space behaves like a river flowing radially toward the singularity in the Schwarzschild spacetime and radially toward infinity in the de Sitter spacetime. In the Schwarzschild-de Sitter spacetime there exists a three-dimensional timelike surface which divides the flow directions of the river of space into two distinct regions: the region outside this surface where space flows radially outwards toward infinity and the region inside this surface where space flows radially toward the central singularity. We also consider the effect of the river of space upon light rays and material particles in the Schwarzschild and the de Sitter spacetimes and show that the river model of space provides an intuitive explanation for the behavior of light and particles at and beyond the event horizons associated with these spacetimes. Finally, a local description of the kinematics of the river of space in terms of the expansion and shear of its velocity field is given. We find that the flow of the river of space in the Scwarzschild-de Sitter spacetime violates the geodesic focusing theorem outside the dividing three-surface.

    Within the theory of general relativity gravitational phenomena are usually attributed to the curvature of four-dimensional spacetime. In this context we are often confronted with the question of how the concept of ordinary physical three-dimensional space fits into this picture. In this work we present a simple and intuitive model of space for both the Schwarzschild spacetime and the de Sitter spacetime in which physical space is defined as a specified set of freely moving reference particles. Using a combination of orthonormal basis fields and the usual formalism in a coordinate basis we calculate the physical velocity field of these reference particles. Thus we obtain a vivid description of space in which space behaves like a river flowing radially toward the singularity in the Schwarzschild spacetime and radially toward infinity in the de Sitter spacetime. We also consider the effect of the river of space upon light rays and material particles and show that the river model of space provides an intuitive explanation for the behavior of light and particles at and beyond the event horizons associated with these spacetimes.

    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 UTSI arcjet model is used to compare the performance of a hydrogen and an ammonia arcjet in the same configuration and at the same electrical power. The predicted specific impulse is 50 percent higher for the hydrogen propellant. Numerical studies made of the effect of transport properties on the performance of a hydrogen arcjet indicate that diffusive transport is very significant even in the supersonic part of the flow, and that relatively small changes in transport properties can have a significant effect on performance. These studies also show that nonequilibrium recombination chemistry can have a large effect on the transport coefficients. This leads to the conclusion that finite rate chemical calculations are necessary if accurate arcjet performance is to be calculated.

    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.

    Education is among the basic, mandatory activities of the European Space Agency (ESA) and aims at all educational levels, from primary school to post-graduate. The primary objective of the ESA educational activities is to enhance the literacy of young people in science and technology and to stimulate interest in STEM (Science - Technology - Engineering - Mathematics) studies and careers, using Space as a theme. The activities mostly follow the IBSE paradigm (Inquiry-Based Science Education) and also aim at the Continuous Professional Development (CPD) for teachers. The backbone supporting all educational activities is the enormous expertise of ESA in the various aspects of Space Science and Technology, like Earth Observation, Space Science (including Astronomy & Astrophysics), Human Spaceflight and Space Technology (launchers, navigation, telecommunications etc.). All educational activities, which are coordinated by the ESA Education Office, are designed for specific age groups, strive to keep the educational community informed and to provide inspirational materials for teachers and students. They can be subdivided in categories, like: Hands-on-projects, opportunities for students, support to teachers, international cooperation activities and outreach initiatives. In addition, ESA develops a variety of educational materials to support teachers in the classroom, both in classic form or on-line, through a network of dedicated websites.

  11. Space architecture education as a part of aerospace engineering curriculum

    NASA Astrophysics Data System (ADS)

    Bannova, Olga; Bell, Larry

    2011-12-01

    Education is particularly important for new fields. In the case of space architecture, there are two core needs: educating the aerospace community about the architect's function and activity and design process within the enterprise; educating space architects and associated specialists about constraints, conditions, and priorities unique to human space systems. These needs can be addressed, respectively, by two key educational tools for the 21st century: introducing the space architecture discipline into the space system engineering curricula; developing space architecture as a distinct, complete training curriculum. New generations of professionals with a space architecture background can help shift professional focus from just engineering-driven transportation systems and "sortie" missions to permanent offworld human presence by offering their inherently integrative design approach to all types of space structures and facilities. Although architectural and engineering approaches share some similarities in solving problems, they also have significant differences. Architectural training teaches young professionals to operate at all scales from the "overall picture" down to the smallest details to provide directive intention - not just analysis - to design opportunities, to address the relationship between human behavior and the built environment, and to interact with many diverse fields and disciplines throughout the project lifecycle.

  12. 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.

    Five traveling exhibits (both large and small) related to space science are currently touring the U. S., and two more have recently been funded by the National Science Foundation and NASA. These extraordinary educational resources address topics like space weather, Mars exploration, cosmology, the results of Hubble Space Telescope, and the origins of stars, planets, and life. The Space Science Institute (SSI) of Boulder, Colorado, plays leadership roles in four of the seven exhibits. This paper will summarize the nature and itineraries of these exhibits, and how they serve as rallying points for education and public outreach activities across the entire spectrum of science communication. The talk will give special attention to workshops SSI has conducted at MarsQuest host sites for museum educators, docents, and local educators to bolster the host site's ability to do programming around the exhibit content. These workshops have shown promise of leaving a host site with a legacy of new educational capabilities and enhanced connectivity with space scientists and educators in the region. The talk will also address progress on the MarsQuest On-Line project which uses the 5000 sq ft (500 sq m) exhibit as a conceptual framework for an interactive website.

    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.

    sergekras@mail.ru The space sciences education and outreach project was initiated at Moscow State University in order to incorporate modern space research into the curriculum popularize the basics of space physics, and enhance public interest in space exploration. On 20 January 2005 the first Russian University Satellite “Universitetskiy-Tatyana” was launched into circular polar orbit (inclination 83 deg., altitude 940-980 km). The onboard scientific complex “Tatyana“, as well as the mission control and information receiving centre, was designed and developed at Moscow State University. The scientific programme of the mission includes measurements of space radiation in different energy channels and Earth UV luminosity and lightning. The current education programme consists of basic multimedia lectures “Life of the Earth in the Solar Atmosphere” and computerized practice exercises “Space Practice” (based on the quasi-real-time data obtained from “Universitetskiy-Tatyana” satellite and other Internet resources). A multimedia lectures LIFE OF EARTH IN THE SOLAR ATMOSPHERE containing the basic information and demonstrations of heliophysics (including Sun structure and solar activity, heliosphere and geophysics, solar-terrestrial connections and solar influence on the Earth’s life) was created for upper high-school and junior university students. For the upper-university students there a dozen special computerized hands-on exercises were created based on the experimental quasi-real-time data obtained from our satellites. Students specializing in space physics from a few Russian universities are involved in scientific work. Educational materials focus on upper high school, middle university and special level for space physics students. Moscow State University is now extending its space science education programme by creating multimedia lectures on remote sensing, space factors and materials study, satellite design and development, etc. The space sciences educational activity of Moscow State University is a non-profit project and is open for all interested parties. “Space schools” for university teachers and students were held in the autumn of 2004 and 2005. The main objective of those schools was to attract interest in space research. Tutors and students who took part in these schools had never before been involved in the space sciences. The idea behind these schools was to join forces: Moscow State University scientists gave space science lectures, students from different universities (Ulianovsk, Samara, Kostroma and other Russian universities) performed the work (prepared educational material) and their university teachers managed the students. After participating in these schools, both students and teachers started to study space science related topics emphasizing the success of these schools. It is important for the educational community to understand what skills future space scientists and space industry employees must be equipped with. In the next years, emphasis is to be placed on space science education at all educational levels and better communication should be practiced between universities and industry.

    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.

    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 on a regular basis. These diverse student experiments and programs fall into one of the following categories: student-developed experiments; students performing classroom versions of ISS experiments; students participating in ISS investigator experiments; students participating in ISS engineering education; education demonstrations and cultural activities. This paper summarizes some of the main student experiments and educational activities that have been conducted on the ISS. It also highlights some upcoming projects.

  11. 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. Drs. Robert Afzal and Joseph Dallas were directors of the SLTC, and led the development and production of active spaceborne, remote-sensing, optical instruments. As a pioneer in the area of photonics, Dr. Dallas led basic research, development, and production of semiconductor laser diode products, improving coupling efficiency through novel physical optics modeling and intracavity phase-correction techniques. He worked for NASA for 15 years, 11 of which were as a civil servant, and 4 of which were as a contractor.

    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.

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

    NASA Astrophysics Data System (ADS)

    Geary, E. E.; Manduca, C. A.; Barstow, D.

    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.

    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.

    Berenguer, Y.

    Achieving sustainable development (social development, economic development and environmental protection) is the priority agenda of world leaders today. The majority of citizens are unaware of the relevance of space research and technology to societal and development issues such as poverty alleviation and the protection and management of the natural resource base. One of the objectives of the Space Education Programme (SEP) of UNESCO, launched in 2002, is to raise awareness of the young generation, particularly those in developing countries, of the important role and contribution of space disciplines for the achievement of sustainable development and to provide them opportunities to acquire and apply such knowledge and skills. Developing public understanding of the benefits of space technology is another objective of SEP. This paper will present the programme's strategy and approaches being taken to reach the programme's objectives, as well as the various mechanisms through which space education and capacity building activities are being developed, coordinated and supported at the national, regional and international levels.

    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 critical thermal control problems and verification of thermal mathematical model results for the space shuttle concept are discussed. The use of a small scale thermal model of the space shuttle is proposed. It was determined that a one-third scale model of the space shuttle would serve as a useful tool throughout the entire thermal design and verification program. The major considerations in modeling the conduction-radiation-convection fields, the level of detail for modeling various systems, preliminary test requirements, and potential applications of the thermal scale model are summarized.

    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 telescopes and special "mobile science" project, which travel to hundreds of school annually, and bring to them mini exhibitions, scientific activities and lectures. Special events are held when something unique happened: in the last years we have had the Galileo special event when the spacecraft arrived at Jupiter; SL-9 event; Mars Pathfinder special event; Mir re- entry event - to name a few. For 11 years, on July 20 we have the Apollo memorial lecture, and a meteors observation night on August 11. The 12 years of experience I have in teaching space sciences subjects to k-12 students, university students and adults, combines with three years as a director of interactive science museum, allowed me to implement my vision of promoting the general knowledge about space and to move a little more in the direction of creating a space oriented, open and globally interacted society in Israel.

    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.

    We explore here the Space Weather Action Center (SWAC) Program, as an example of NASA initiatives in education. Many human activities in space can be disrupted by space weather. The main objective of this program is to enable students to produce space weather forecasts by accessing current NASA data. Implementation of the SWAC Program requires: technological resources, online materials, and systematic work. Instructional guides, materials and methods are explained on the Space Weather Action Center Web site (http://sunearthday.nasa.gov/swac). Ultimately, students’ forecasts can be presented through a variety of accessible media including inexpensive video editing software and/or already existing school-based broadcast studios. This cross-curricular program is targeted to middle and high school and can be applied in almost all educational contexts as the number of schools with computer and internet access increases worldwide. SWAC is a pioneer initiative that contributes to fostering student interest in STEM and promotes their intellectual autonomy. Through SWAC, they get to act like real scientists by accessing, analyzing, recording, and communicating space weather forecasts in a professional approach.

    McKenzie, D. J.; Cartnell, M. P.

    Large structures in space are an essential milestone in the path of many projects, from solar power collectors to space stations. In space, as on Earth, these large projects may be split up into more manageable sections, dividing the task into multiple replicable parts. Specially constructed spider robots could assemble these structures piece by piece over a membrane or space- web, giving a method for building a structure while on orbit. The modelling and applications of these space-webs are discussed, along with the derivation of the equations of motion of the structure. The presentation of some preliminary results from the solution of these equations will show that space-webs can take a variety of different forms, and give some guidelines for configuring the space-web system.

    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.

    Space analysis is an important procedure by orthodontists to determine the amount of space available and required for teeth alignment during treatment planning. Traditional manual methods of space analysis are tedious and often inaccurate. Computer-based space analysis methods that work on 2D images have been reported. However, as the space problems in the dental arch exist in all three planes of space, a full 3D analysis of the problems is necessary. This paper describes a visualization and measurement system that analyses 3D images of dental plaster models. Algorithms were developed to determine dental arches. The system is able to record the depths of the Curve of Spee, and quantify space liabilities arising from a non-planar Curve of Spee, malalignment and overjet. Furthermore, the difference between total arch space available and the space required to arrange the teeth in ideal occlusion can be accurately computed. The system for 3D space analysis of the dental arch is an accurate, comprehensive, rapid and repeatable method of space analysis to facilitate proper orthodontic diagnosis and treatment planning.

  7. A synergy model of nursing education.

    This article proposes the use of a synergy model of nursing education that can be used as a blueprint for the nurse educator and learner to facilitate acquisition of knowledge, skills, and values across a nursing career. Too often, a mismatch occurs between educators, learners, and the system in which they practice. A synergy model provides a way to close this gap and enhance the connection between the three entities. This model may be implemented in academic and healthcare institutions for the purpose of improving nursing education outcomes. PMID:17149042

    Space weather refers to conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-borne and ground-based technological systems and that affect human life or health. In order to make the real- or faster than real-time numerical prediction of adverse space weather events and their influence on the geospace environment, high-performance computational models are required. The main objective in this article is to explore the application of programmable graphic processing units (GPUs) to the numerical space weather modeling for the study of solar wind background that is a crucial part in the numerical space weather modeling. GPU programming is realized for our Solar-Interplanetary-CESE MHD model (SIP-CESE MHD model) by numerically studying the solar corona/interplanetary solar wind. The global solar wind structures is obtained by the established GPU model with the magnetic field synoptic data as input. The simulated global structures for Carrington rotation 2060 agrees well with solar observations and solar wind measurements from spacecraft near the Earth. The model's implementation of the adaptive-mesh-refinement (AMR) and message passing interface (MPI) enables the full exploitation of the computing power in a heterogeneous CPU/GPU cluster and significantly improves the overall performance. Our initial tests with available hardware show speedups of roughly 5x compared to traditional software implementation. This work presents a novel application of GPU to the space weather study.

  9. 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.

    2010-01-01

    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.

    Currently NASA, USA, has under active study and development several large structures for deployment in space. These include for instance beam-like trusses to serve as antenna masts and/or basic building blocks for Space Station construction. An important design consideration is that of assuring adequate stability of the structure in the space environment and in addition in the case of antennas, meeting stringent pointing accuracy requirements. This paper addresses some of the basic design considerations involved such as: (1) modeling flexible multibody dynamics, including sensors and actuators, (2) identifying/monitoring model parameters in orbit, and (3) integrated controls-structures optimization with emphasis on novel concepts and techniques.

    2003-01-01

    It's a challenge educators at all grade levels face: How do you teach subjects your students can't see, touch, or hear? You do it with models--which have gained new importance since the National Science Education Standards specifically recommended using models as an organizing framework for teaching and understanding science. Whether your lessons concern molecules or Mars, Understanding Models in Earth and Space Science offers practical guidance. It's designed to help you understand the full range of models available to illustrate abstract concepts, demonstrate complex ideas, or teach about things students can't see. The book provides an in-depth look at specific kinds of models--what they are, how they can be designed, the best ways to use them, and possible shortcomings. Among the chapter topics are concrete models; mathematical models; similes, analogies, and metaphors; computer models; and inquiry and model building. Itself a model of good modeling, the book offers abundant examples (including drawing parallels between seemingly unrelated topics, such as how tornadoes are like vacuum cleaners) and plentiful background specific to Earth science teachers. Understanding Models is the result of a partnership between NSTA and the U.S. Environmental Protection Agency's Office of Pollution Prevention and Toxics.

    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.

    The AX-5 is an all metal Extra-vehicular (EVA) space suit currently under consideration for use on Space Station Freedom. A reliability model was developed based on the suit's unique design and on projected joint cycle requirements. Three AX-5 space suit component joints were cycled under simulated load conditions in accordance with NASA's advanced space suit evaluation plan. This paper will describe the reliability model developed, the results of the cycle testing, and an interpretation of the model and test results in terms of projected Mean Time Between Failure for the AX-5. A discussion of the maintenance implications and life cycle for the AX-5 based on this projection is also included.

  18. The organizations for space education and outreach programs in the Republic of Korea

    Lee, Jeongwon; Jo, Hyun-Jung; Choi, Jae Dong

    2011-09-01

    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 education and outreach for the Korean public and students. If these three organizations cooperate with each other and develop systematic programs of space education and outreach for the people, they will prepare a base for growth and progress in future space science and technology in Korea.

    Scientists and educators at Baylor College of Medicine are using space life sciences research areas as themes for middle school science and health instructional materials. 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.

  1. The Space Production Model of Gravity

    NASA Astrophysics Data System (ADS)

    Bowen, Richard

    2014-03-01

    The Space Production Model of gravity is based on the premise that mass emits space and proposes that this is the mechanism by which mass curves space-time. It states that the pressure waves created by the production of space are responsible for the ``attractive force'' of gravity while the actual space generated is responsible for its ``repulsive force.'' The Space Production Model proposes a new mechanism of attraction based on wave interference and it provides a source for dark energy that is consistent with the Friedman equation. By using only observational data it is able to accurately predict the current mass of the universe as well as changes in the Hubble constant over time. It is consistent with inflation and provides a solution to the ``flatness problem.'' It proposes a radically different model of a black hole that allows one to determine the amount of space emitted by a specific amount of mass per unit time. It is testable in that recession rates of galaxies should correlate to their mass. Whether it is able to reconcile General Relativity with quantum mechanics is yet to be determined.

This paper gives an introduction of the massless relativistic string in the Lund Model and shows how it can be modified with a simple assumption to produce formulas for meson production cross sections for space radiation research. The results of the string model are compared with inclusive pion production data from proton-proton collision experiments.

    Educating nursing students for entry level practice in complex health care settings is a concern in Canada and many other countries. National groups have called for improved practice education to better prepare students for actual practice. The purposes of this paper are identification and critical analysis of current practice education models. Ten basic model types were identified in the literature: faculty-supervised practicum, preceptorship, education unit, joint appointment, secondment, affiliate position, internship, co-operative education, work-study and undergraduate nurse employment. Key features, benefits and limitations of each model are discussed. Emerging developments in practice education are increased inter-professional and community-based practice education, and new partnerships among academic and practice organizations. These developments are intended to alleviate model limitations, ease pressures from organizational contexts and respond to large integrated health care systems. Evidence-based research for practice education is beginning to be apparent. Further research is needed that compares models and examines learning, patient care outcomes and costs. PMID:17629596

Such technologies offer promise of increasing the performance of in-space chemical propulsion for energetic space missions. A mass model for pressure-fed, Earth and space-storable, advanced chemical propulsion systems (ACPS) was developed in support of the NASA MSFC In-Space Propulsion Program. Data from flight systems and studies defined baseline system architectures and subsystems and analyses were formulated for parametric scaling relationships for all ACPS subsystem. The paper will first provide summary descriptions of the approaches used for the systems and the subsystems and then present selected analyses to illustrate use of the model for missions with characteristics of current interest.

    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.

    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.

    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.

    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.

    2015-04-01

    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.

    Chapes, Stephen Keith; Ganta, Roman Reddy; Chapers, S. K. (Principal Investigator)

    2005-01-01

    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.

    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.

    Although it is well known that radiation causes mutational damage, little is known about the biological effects of long-term exposure to radiation in space. Exposure to radiation can result in serious heritable defects in experimental animals, and in humans, susceptibility to cancer, radiation-sickness, and death at high dosages. It is possible to do ground controlled studies of different types of radiation on experimental animals and to physically measure radiation on the space station or on space probes. However, the actual biological affects of long-term exposure to the full range of space radiation have not been studied, and little information is available about the biological consequences of solar flares. Biological systems are not simply passive recording instruments. They respond differently under different conditions, and thus it is important to be able to collect data from a living animal. There are technical difficulties that restrict the placement of an experimental organism in a space environment for long periods of time, in a manner that allows for the recovery of genetic data. Use of the self-fertilizing hermaphroditic nematode, Caenorhabditis elegans offers potential for the design of a biological dosimeter. In this paper, we describe the advantages of this model system and review the literature of C. elegans in space. PMID:16038089

    A demonstration of an integrated fault propagation model for Space Station Freedom is described. The demonstration uses a HyperCard graphical interface to show how failures can propagate from one component to another, both within a system and between systems. It also shows how hardware failures can impact certain defined functions like reboost, atmosphere maintenance or collision avoidance. The demonstration enables the user to view block diagrams for the various space station systems using an overview screen, and interactively choose a component and see what single or dual failure combinations can cause it to fail. It also allows the user to directly view the fault model, which is a collection of drawing and text listings accessible from a guide screen. Fault modeling provides a useful technique for analyzing individual systems and also interactions between systems in the presence of multiple failures so that a complete picture of failure tolerance and component criticality can be achieved.

    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-Picosatellite Orbital Deployer (P-POD), was developed and built by students at California Polytechnic State University (Cal Poly). Integrating a P-POD on a NASA ELV was not an easy task. The creation of new processes and requirements as well as numerous reviews and approvals were necessary within NASA before the first ELaNa mission could be attached to a NASA launch vehicle (LV). One of the key objectives placed on an ELaNa mission is that the CubeSat and PPOD does not increase the baseline risk to the primary mission and launch vehicle. The ELaNa missions achieve this objective by placing a rigorous management and engineering process on both the LV and CubeSat teams. So, what is the future of ELaNa? Currently there are 16 P-POD missions manifested across four launch vehicles to support educational CubeSats selected under the NASA CubeSat Initiative. From this initiative, a rigorous selection process produced 22-student CubeSat missions that are scheduled to fly before the end of 2012. For the initiative to continue, organizations need to submit proposals to the annual CubeSat initiative call so they have the opportunity to be manifested and launched.

    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 schemes. Depending on the application, we find that different time stepping methods are optimal. Several of the time integration schemes exploit the block-based granularity of the grid structure. The framework and the adaptive algorithms enable physics based space weather modeling and even forecasting.

    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.

    2011-11-21

    We discuss Global Static Spherically Symmetric space-time models of mass $m$ with regular sources at the origin and asymptotically Minkowskian behavior at infinity; the interior model and the exterior one being matched at the radius $R$ of the source in the sense of Lichnerowicz. The global models depend in general on $R$ through a function $Q$ of $m$ and $R$. Although $R$ would be an spurious parameter if the exterior model was considered alone, it becomes intrinsic for the global model. The physical implication is that $R$ as well as $m$ determine, at some order of approximation, the dynamics of orbiting objects or viceversa that this dynamics puts conditions on the physical state of the source.

  17. Dynamic multibody modeling for tethered space elevators

    NASA Astrophysics Data System (ADS)

    Williams, Paul

    2009-08-01

    This paper presents a fundamental modeling strategy for dealing with powered and propelled bodies moving along space tethers. The tether is divided into a large number of discrete masses, which are connected by viscoelastic springs. The tether is subject to the full range of forces expected in Earth orbit in a relatively simple manner. Two different models of the elevator dynamics are presented. In order to capture the effect of the elevator moving along the tether, the elevator dynamics are included as a separate body in both models. One model treats the elevator's motion dynamically, where propulsive and friction forces are applied to the elevator body. The second model treats the elevator's motion kinematically, where the distance along the tether is determined by adjusting the lengths of tether on either side of the elevator. The tether model is used to determine optimal configurations for the space elevator. A modal analysis of two different configurations is presented which show that the fundamental mode of oscillation is a pendular one around the anchor point with a period on the order of 160 h for the in-plane motion, and 24 h for the out-of-plane motion. Numerical simulation results of the effects of the elevator moving along the cable are presented for different travel velocities and different elevator masses.

    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.

Particular attention is given to the aim and the nature of the three programs involved: the Centers for the Commercial Development of Space (CCDSs) (funded by NASA), which are currently involving about 250 companies and 88 universities as participants; the Space Industry Development Centers (SIDCs) (funded by the Australian Space Office): and the Cooperative Research Centers (CRCs) (funded by the Federal Government), which are not limited to the space area but are open to activities ranging from medical research to waste-water treatment. It is emphasized that, while the main aim of the CCDS, SIDC, and CRC programs is to develop space expertise, space education is a very significant byproduct of the activity of these agencies.

    NASA Astrophysics Data System (ADS)

    1996-03-01

    In this paper, we describe a method of 3D modeling based on photographs for real-time graphics system of educational use. The method uses few basic models like squares, spheres and so on, and a 3D model is constructed by modifying basic models, guided by parameters. For example, we made an educational real-time graphics system of the deep space, having galaxies' 3D models. A typical galaxy called spiral galaxy consists of two parts; a spherical center part named bulge, and a whirlpool convex-lens shaped surrounding part named galactic disc. Galaxies' photographs are taken from a limited angle, because they are too far away, and viewed only from the earth. So a galaxies' photograph is whether in a whirlpool form, a convex-lens form, or in a slant form between the two forms. Therefore our method puts a sphere model at the bulge position, and a convex-lens model formed by a sphere metamorphism at the galactic disc position. Parameters are used to change galaxies' position, size, XYZ-axes metamorphism and rotation. Thus we get a 3D galaxy model corresponding to the photograph, and learners can look at a 3D galaxy from any viewpoint and view direction. In this way, we construct realistic 3D models. The amount of rendering computation is still low. Thus real-time rendering images are produced freely from a moving viewpoint and view direction.

    Ivantchenko, Anton; Nieminen, Petteri; Incerti, Sebastien; Santin, Giovanni; Ivantchenko, Vladimir; Grichine, Vladimir; Allison, John

    The space radiation environment includes wide varieties of particles from electrons to heavy ions. In order to correctly predict the dose received by astronauts and devices the simulation models must have good applicability and produce accurate results from 10 MeV/u up to 10 GeV/u, where the most radioactive hazardous particles are present in the spectra. Appropriate models should also provide a good description of electromagnetic interactions down to very low energies (10 eV/u - 10 MeV/u) for understanding the damage mechanisms due to long-term low doses. Predictions of biological dose during long interplanetary journeys also need models for hadronic interactions of energetic heavy ions extending higher energies (10 GeV/u - 100 GeV/u, but possibly up to 1 TeV/u). Geant4 is a powerful toolkit, which in some areas well surpasses the needs from space radiation studies, while in other areas is being developed and/or validated to properly cover the modelling requirements outlined above. Our activities in ESA projects deal with the research and development of both Geant4 hadronic and electromagnetic physics. Recently the scope of verification tests and benchmarks has been extended. Hadronic tests and benchmarks run proton, pion, and ion interactions with matter at various energies. In the Geant4 hadronic sub-libraries, the most accurate cross sections have been identified and selected as a default for all particle types relevant to space applications. Significant developments were carried out for ion/ion interaction models. These now allow one to perform Geant4 simulations for all particle types and energies relevant to space applications. For the validation of ion models the hadronic testing suite for ion interactions was significantly extended. In this work the results of benchmarking versus data in a wide energy range for projectile protons and ions will be shown and discussed. Here we show results of the tests runs and their precision. Recommendations for Geant4 users will be given.

  18. 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.

  19. Edgeworth streaming model for redshift space distortions

    E-print Network

    Uhlemann, Cora

    2015-01-01

    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 r...

  20. Modeling utilization distributions in space and time

    USGS Publications Warehouse

    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.

  1. Models of space averaged energetics of plates

    NASA Technical Reports Server (NTRS)

    Bouthier, O. M.; Bernhard, R. J.

    1990-01-01

    The analysis of high frequency vibrations in plates is of particular interest in the study of structure borne noise in aircrafts. The current methods of analysis are either too expensive (finite element method) or may have a confidence band wider than desirable (Statistical Energy Analysis). An alternative technique to model the space and time averaged response of structural acoustics problems with enough detail to include all significant mechanisms of energy generation, transmission, and absorption is highly desirable. The focus of this paper is the development of a set of equations which govern the space and time averaged energy density in plates. To solve this equation, a new type of boundary value problem must be treated in terms of energy density variables using energy and intensity boundary conditions. A computer simulation verification study of the energy governing equation is performed. A finite element formulation of the new equations is also implemented and several test cases are analyzed and compared to analytical solutions.

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. In conjunction with government and contractor personnel in the Human-Computer Interaction Lab, the PDRS was identified as the most accessible system for the demonstration. Pursuant to this a PDRS simulation was obtained from the HCIL and an initial knowledge engineering effort was conducted to understand the operator's tasks in the PDRS application. The preliminary results of the knowledge engineering effort and an initial formulation of an operator function model (OFM) are contained in the appendices.

    2003-06-04

    The Fermilab Booster is a bottleneck limiting the proton beam intensity in the accelerator complex. A study group has been formed in order to have a better understanding of this old machine and seek possible improvements. The work includes lattice modeling, numerical simulations, bench measurements and beam studies. Based on newly obtained information, it has been found that the machine acceptance is severely compromised by the orbit bump and dogleg magnets. This, accompanied by emittance dilution from space charge at injection, is a major cause of the large beam loss at the early stage of the cycle. Measures to tackle this problem are being pursued.

    Hye, Abdul; Lin, Chin H.

    1988-01-01

    The Space Station Active Thermal Control System (ATCS) has been modeled using modified SINDA/SINFLO programs to solve two-phase Thermo-fluid problems. The modifications include changes in several subroutines to incorporate implicit solution which allows larger time step as compared to that for explicit solutions. Larger time step saves computer time but involves larger computational error. Several runs were made using various time steps for the ATCS model. It has been found that for a reasonable approach, three times larger time step as compared to that used in explicit method is a good value which will reduce the computer time by approximately 50 percent and still maintain the accuracy of the output data to within 90 percent of the explicit values.

    Many studies have been carried out since T.Padmanabhan proposed that the cosmic acceleration can be understood from the perspective that spacetime dynamics is an emergent phenomenon. Motivated by such a new paradigm, we firstly study the de Sitter universe from emergence of space. After that we investigate the universes in general cases and then narrow down our discussions into one of them with a detailed discussion of the possibility in describing our real universe classically. Furthermore, a constraint on $Ht$ and a estimated value of $\\tilde\\Omega _{\\Lambda}$ (caused by $\\rho _{vac}$) can be derived from our model, the comparison with experiments is also presented. The results show the validity of our model.

  6. Granger causality for state-space models.

    PubMed

    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.

    As part of the NASA Education Forums, the Higher Education Working Group (HEWG) strives to support undergraduate science education through a variety of activities. These activities include: providing resource that incorporate space science topics into the existing undergraduate curriculum, understanding the role that community colleges play in STEM education and preparing STEM teachers, and identifying issues in diversity related to STEM education. To assess the best way of including space science into the undergraduate curriculum, the HEWG held a series of workshops and conducted surveys of undergraduate faculty who are conducting research in space science. During this engagement, the faculty expressed a need for a centralized repository of materials that can be used as part of already existing undergraduate courses in astronomy, physics, and earth science. Such a repository has since been developed, the 'EarthSpace Higher Education Clearing House (http://www.lpi.usra.edu/earthspace/) and it is still growing. Additional community tools, such as a newsletter, are provided through this website. To better understand the role and needs of community colleges, the HEWG undertook and extensive survey of community college STEM faculty. 187 faculty responded to the survey and the results show the extensive teaching load these faculty have, as well as the diverse demographics and the extent to which STEM teachers begin their preparation at 2 year institutions. Finally, the HEWG has begun to work on understanding the issues faced in increasing the diversity of the STEM work force. Progress and results of all this work will be summarized in this presentation.

    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.

    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.

    In a systematic effort to improve the preparation of future science teachers, scholars coordinated by the CAPER Center for Astronomy & Physics Education Research are providing a series of high-quality, 2-day professional development workshops, with year-round follow-up support, for college and university professors who prepare future science teachers to work with highly diverse student populations. These workshops focus on reforming and revitalizing undergraduate science teaching methods courses and Earth and Space science content courses that future teachers most often take to reflect contemporary pedagogies and data-rich problem-based learning approaches steeped in authentic scientific inquiry, which consistently demonstrate effectiveness with diverse students. Participants themselves conduct science data-rich research projects during the institutes using highly regarded approaches to inquiry using proven models. In addition, the Institute allocates significant time to illustrating best practices for working with diverse students. Moreover, participants leave with a well-formulated action plan to reform their courses targeting future teachers to include more data-rich scientific inquiry lessons and to be better focused on improving science education for a wide diversity of students. Through these workshops faculty use a backwards faded scaffolding mechanism for working inquiry into a deeper understanding of science by using existing on-line data to develop and research astronomy, progressing from creating a valid and easily testable question, to simple data analysis, arriving at a conclusion, and finally presenting and supporting that conclusion in the classroom.

    Government schools in Congo kinshasa are not providing quality education to the masses since many years, and this phenomenon has not escaped the eyes of experts, activists, and policy makers. However, there seems to be a general perception that the main, and sometimes even the sole, source of this problem are the low levels of government expenditure of education. And to prove their case supports of this view cite educational expenditure to GDP ratios in Congo kinshasa in comparison with that of some other nations. Though there may be reasonable arguments to increase the level of government expenditure on education, such hijacking of public debate to focus on - the level of expenditure - often overlooks more important issues. Contrary to common perception the level of per student expenditure on government schools in Delhi is reasonable, ranging from Fc.6000 to Fc.12000 p.a. There are a number of organisational deficiencies which do not create checks and balances for appropriate utilization of fund. Moreover, the division of these funds among social groups and for different purposes is also questionable. Though, female literacy lags significantly behind male literacy, about 15% points, extra resources provided for female education are insignificant. And in some schemes such as the one run for 'street children' and 'child labourers', large amounts are budgeted year after year without a single French congolese being spent. Also government schools catering to richer regions of Kinshasa seem to be spending more per child as compared to the poorer counterparts. The paper also proposes an education voucher model, which may have the potential to address some of the issues raised in the paper. Trends in expenditure under some schemes have been studied in relation to the purpose of expenditure. The issue of government expenditure on education is a complex one, and public space should be utilized to discuss them as they are, rather than reducing discussion to dogmatic wars aimed at increasing the levels of expenditure. Though, one may agree or disagree with the methods and findings of the author, hopefully the paper highlight the complexity of the issue at hand, and the need to understand the institutional deficiencies and allocative inefficiencies in government expenditure on education.

  10. NASA Aquarius: Sea Surface Salinity from Space Education & Public Outreach

    NSDL National Science Digital Library

    deCharon, Annette

    Aquarius is a focused satellite mission to measure global sea surface salinity. Launching in 2009, this mission will provide the first global map of sea surface salinity with unprecedented accuracy, resolution and coverage. The importance of salinity measurements in understanding coastal ocean processes is critical. Because of its dynamic range in the coastal oceans, salinity is a critical factor in understanding and predicting biological and physical processes and their interactions with the food Web, climate, and global water cycle. Aquariusâ??s pioneering efforts to deliver the â??missing pieces of the climate puzzleâ?ť will undoubtedly intrigue informal audiences via the activities and information contained in this Website. Moreover, climate and its influence on humankind is an integral part of K-16 formal education and common to national learning standards. The goal of the Education and Outreach component of Aquarius is to teach fundamental concepts about salinity variations and the role these changes play in controlling global ocean circulation and Earthâ??s climate. Education products will appear as modules addressing the missionâ??s goals and purpose, augment existing El Nino/La Nina materials with salinity based content, provide on-line interactive tools demonstrating environmental change through data sets and in situ time-series analysis, and engage students in activities designed to demonstrate salt-water interactions.

  13. Planetarium inversum — A space vision for earth education

    NASA Astrophysics Data System (ADS)

    Lötsch, B.

    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 CO 2).

    2001-01-01

    The projected radiation levels within the International Space Station (ISS) have been criticized by the Aerospace Safety Advisory Panel in their report to the NASA Administrator. Methods for optimal reconfiguration and augmentation of the ISS shielding are now being developed. The initial steps are to develop reconfigurable and realistic radiation shield models of the ISS modules, develop computational procedures for the highly anisotropic radiation environment, and implement parametric and organizational optimization procedures. The targets of the redesign process are the crew quarters where the astronauts sleep and determining the effects of ISS shadow shielding of an astronaut in a spacesuit. The ISS model as developed will be reconfigurable to follow the ISS. Swapping internal equipment rack assemblies via location mapping tables will be one option for shield optimization. Lightweight shield augmentation materials will be optimally fit to crew quarter areas using parametric optimization procedures to minimize the augmentation shield mass. The optimization process is being integrated into the Intelligence Synthesis Environment s (ISE s) immersive simulation facility at the Langley Research Center and will rely on High Performance Computing and Communication (HPCC) for rapid evaluation of shield parameter gradients.

    NASA Astrophysics Data System (ADS)

    Fisher, Diane K.; Leon, N. J.

    2006-12-01

    The Space Place is an integrated NASA education and public outreach program, so far representing over 40 different NASA missions. It combines Web-based, printed, and externally published media to reach underserved audiences across the nation. Its primary mission is to develop and provide a highly desirable suite of attractive and educational products designed to appeal to and immerse the general public in space exploration. Its primary target audience is elementary school age kids. The program has developed an extensive network of partnerships with museums and libraries in rural areas, English and Spanish language newspapers, astronomy societies, rocketry clubs, and national youth organizations. Materials are distributed monthly through all these channels. Originally a New Millennium Program (NMP) outreach effort only, it is open to all NASA missions. NMP (a NASA-level program managed out of the Jet Propulsion Laboratory) continues to provide the base of support to build and maintain the outreach program’s infrastructure. Obtaining independent evaluation and reporting of the effectiveness of the program is one of NASA’s requirements for education and public outreach efforts. The Program Evaluation and Research Group (PERG) at Lesley University, Cambridge, MA, was retained to perform this service for The Space Place. PERG is also evaluating education and public outreach programs for NASA’s Science Mission Directorate. PERG recently delivered a report evaluating The Space Place program. Using both qualitative and quantitative methods, PERG surveyed representative samples of Space Place partner museums, astronomy clubs, and newspapers. The survey included questions about all the products the program provides. The report concludes that The Space Place fills a niche by serving small institutions, giving them a personal alliance with NASA that they would otherwise not have. By providing free, quality materials, The Space Place program provides these under-served populations access to space and science as only NASA can.

    After a brief introduction to Probability Bracket Notation (PBN) for discrete random variables in time-independent probability spaces, we apply both PBN and Dirac notation to investigate probabilistic modeling for information retrieval (IR). We derive the expressions of relevance of document to query (RDQ) for various probabilistic models, induced by Term Vector Space (TVS) and by Concept Fock Space (CFS). The inference network model (INM) formula is symmetric and can be used to evaluate relevance of document to document (RDD); the CFS-induced models contain ingredients of all three classical IR models. The relevance formulas are tested and compared on different scenarios against a famous textbook example.

    Planetary science education needs new forms of teaching. Our group have various initiatives of which a new atlas series about the studies of the Solar System materials, planetary surfaces and atmospheres, instrumental field works with robots (landers, rovers) and other beautiful field work analog studies. Such analog studies are both used in comparative planetology as scientific method and it also plays a key role in planetary science education. With such initiatives the whole system of the knowledge of terrestrial geology can be transformed to the conditions of other planetary worlds.

  17. Promoting Space Education and Awareness in Pakistan- Initiatives, Achievements, Challenges and Issues

    NASA Astrophysics Data System (ADS)

    Jagirani, Aisha

    With about 180 million inhabitants, Pakistan is the sixth most populous and the 34th largest country in the world in terms of area. Pakistan's economy, which is pre-dominantly based on agriculture, is the 26th largest in the world in terms of purchasing power parity and 45th largest in terms of nominal GDP. Pakistan is counted among the Next Eleven (N11) countries that have the potential to become the world's largest economies in the 21st century. Despite considerable potential to develop into a stable, moderate and democratic state, major challenges of internal security, poor agricultural productivity, inadequate infrastructure, food insecurity, insufficient health and educational facilities, depletion of natural resources, rapid environmental degradation and recurring natural disasters have burdened the country and have hampered sustainable development of Pakistan. Space technology applications offer a cost-effective means of addressing many of the above mentioned issues and have made impressive advances in the last few years in different countries in the region. Unfortunately, for various reasons, Pakistan has not been able to fully exploit the benefits of space technology and its applications to meet the challenges she faces. One of the reasons is lack of awareness and understanding by planners, decision-makers and users about the potential benefits of space technology in planning and implementation of developmental plans as well as good governance. Similarly, Pakistan's space program enjoys little public support due, primarily, to lack of awareness of the benefits space offers and the ubiquitousness of space applications in modern life. There is thus an acute need to create awareness and educate all segments of the society and stakeholders in Pakistan about the potential benefits of space technology and its applications. In the past ten years, many initiatives have been taken to promote space education and awareness for students as well as decision-makers in Pakistan. These include establishment of space science departments in universities, developing space-specific educational institutes, cooperation and collaboration between universities and SUPARCO, outreach to schools, and holding of short courses, seminars and symposia. To create awareness among the general public, efforts are being made to air programs on the electronic media. This paper covers achievements of Pakistan in promoting space education and awareness in the country and the related issues and impediments to pursue these programs.

  18. Climate Change Education Today in K-12: What's Happening in the Earth and Space Science Classroom?

    NASA Astrophysics Data System (ADS)

    Holzer, M. A.; National Earth Science Teachers Association

    2011-12-01

    Climate change is a highly interdisciplinary topic, involving not only multiple fields of science, but also social science and the humanities. There are many aspects of climate change science that make it particularly well-suited for exploration in the K-12 setting, including opportunities to explore the unifying processes of science such as complex systems, models, observations, change and evolution. Furthermore, this field of science offers the opportunity to observe the nature of science in action - including how scientists develop and improve their understanding through research and debate. Finally, climate change is inherently highly relevant to students - indeed, students today will need to deal with the consequences of the climate change. The science of climate change is clearly present in current science education standards, both at the National level as well as in the majority of states. Nonetheless, a significant number of teachers across the country report difficulties addressing climate change in the classroom. The National Earth Science Teachers Association has conducted several surveys of Earth and space science educators across the country over the past several years on a number of issues, including their needs and concerns, including their experience of external influences on what they teach. While the number of teachers that report external pressures to not teach climate change science are in the minority (and less than the pressure to not teach evolution and related topics), our results suggest that this pressure against climate change science in the K-12 classroom has grown over the past several years. Some teachers report being threatened by parents, being encouraged by administrators to not teach the subject, and a belief that the "two sides" of climate change should be taught. Survey results indicate that teachers in religious or politically-conservative districts are more likely to report difficulties in teaching about climate change than in other areas of the country. This presentation will provide an overview of our most recent survey results on climate change education in the K-12 Earth and space science classroom, including highlighting some of the strategies that teachers are using to bring this critically important area of science to their students.

    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.

    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.

    Alexander, J. Iwan D.; Rosenberger, Franz; Nadarajah, Arunan; Ouazzani, Jalil; Amiroudine, Sakir

    1990-01-01

    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.

  15. Lessons Learned about Educational Programming Associated with Space Science Traveling Exhibits

    NASA Astrophysics Data System (ADS)

    Morrow, C.; Edwards, C.; McLain, B.; Dusenbery, P.

    Events such as the Mars rover landings bring much public attention and provide excellent reasons for substantive educational outreach to educators and the public. In the fall of 2003, the Space Science Institute (SSI) of Boulder, Colorado (USA) led the refurbishment and redeployment of the 5000 sq. ft MarsQuest traveling exhibition. Prior to this, MarsQuest had completed a highly successful 3-year tour of the US. Earlier in 2003, SSI launched the 600 sq. ft. ``mini-MarsQuest'' exhibit called Destination Mars. This paper will report on the lessons we have learned regarding the educational programming associated with these exhibits. In this context, ``educational programming'' refers to: 1) workshops for museum educators and docents at exhibit host sites; 2) workshops for local educators who will bring their students to visit the exhibit; 3) materials and resources to support science center programming such as school-group visits, family days, and camp-ins; and 4) public talks by scientists. We will focus this paper on our 3 years of experience with the Mars exhibits, plus the results of a formal evaluation being conducted in collaboration with Randi Korn & Associates. The lessons learned will be of great value to the educational programming of future SSI traveling exhibits. In addition, we expect that many of our lessons learned will be of broader value to any scientist or educator who works in collaboration with science centers and museums.

    The NASA Science Education and Public Outreach Forums have developed a digital library--NASAWavelength.org--that enables easy discovery and retrieval of thousands of resources from the NASA Earth and space science education portfolio. The system has been developed based on best practices in the architecture and design of web-based information systems. The design style and philosophy emphasize simple, reusable data and services that facilitate the free flow of data across systems. The primary audiences for NASA Wavelength are STEM educators (K-12, higher education and informal education) as well as scientists, education and public outreach professionals who work with K-12, higher education, and informal education. A NASA Wavelength strandmap service features the 19 AAAS strandmaps that are most relevant to NASA science; the service also generates all of the 103 AAAS strandmaps with content from the Wavelength collection. These maps graphically and interactively provide connections between concepts as well as illustrate how concepts build upon one another across grade levels. New features have been developed for this site based on user feedback, including list-building so that users can create and share individual collections within Wavelength. We will also discuss potential methods for integrating the Next Generation Science Standards (NGSS) into the search and discovery tools on NASA Wavelength.

    From the dawn of consciousness, humans have looked up and wondered about what the universe holds. It is that sense of wonder and thirst for knowledge that astronomy has helped fuel. In this paper we look at how education and public outreach has been a major element in preparing the next generation of astronomers and in sharing with the public the excitement of discoveries we make when we explore the Universe. The National Aeronautics and Space Administration (NASA) has a clear set of goals and objectives related to education and public outreach. These goals follow directly from NASA's mission ``to inspire the next generation of explorers''. Making progress towards achieving these goals has become an important part of the broad justification for public support of space science. Here we will describe a number of education and public outreach initiatives that are examples of the plethora of NASA funded programs and resources.

    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 such as BRRISON, LADEE, MAVEN, INSIGHT, OSIRIS-REX and ground-based observatories. Streamlining the ingest process also benefits the continued processing of PDS3 data. We will report on our progress and status.

  4. Lunar and Meteorite Sample Education Disk Program - Space Rocks for Classrooms, Museums, Science Centers, and Libraries

    NASA is eager for students and the public to experience lunar Apollo samples and meteorites first hand. Lunar rocks and soil, embedded in Lucite disks, 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 reveals the early history of our Earth-Moon system and meteorites reveal much of the history of the early solar system. The rocks help educators make the connections to this ancient history of our planet and solar system and the basic processes accretion, differentiation, 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 many NASA planetary missions. 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 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 orange glass from a pyroclastic deposit. Each Meteorite Disk contains two ordinary chondrites, one carbonaceous chondrite, one iron, one stony iron, and one achondrite. These samples will help educators share the early history of the solar system with students and the public. Educators may borrow either lunar or meteorite disks and the accompanying education materials through the Johnson Space Center Curatorial Office. In trainings provided by the NASA Aerospace Education Services Program specialists, educators certified to borrow the disk learn about education resources, the proper use of the samples, and the special security for care and shipping of the disks. The Lunar and Meteorite Sample Education Disk Program will take NASA exploration to more people. Getting Space Rocks out to the public and inspiring the public about new space exploration is the focus of the NASA disk loan program.

    The Space Experiment Module (SEM) concept is one of a number of education initiatives being pursued by the NASA Shuttle Small Payloads Project (SSPP) in an effort to increase educational access to space by means of Space Shuttle Small Payloads and associated activities. In the SEM concept, NASA will provide small containers ('modules') which can accommodate small zero-gravity experiments designed and constructed by students. A number, (nominally ten), of the modules will then be flown in an existing Get Away Special (GAS) carrier on the Shuttle for a flight of 5 to 10 days. In addition to the module container, the NASA carrier system will provide small amounts of electrical power and a computer system for controlling the operation of the experiments and recording experiment data. This paper describes the proposed SEM carrier system and program approach.

    2010-12-01

    The Education and Public Outreach (E/PO) office in The Johns Hopkins University Applied Physics Laboratory (APL) Space Department strives to excite and inspire the next generation of explorers by creating interactive education experiences. Since 1959, APL engineers and scientists have designed, built, and launched 61 spacecraft and over 150 instruments involved in space science. With the vast array of current and future Solar System exploration missions available, endless opportunities exist for education programs to incorporate the real-world science of these missions. APL currently has numerous education and outreach programs tailored for K-12 formal and informal education, higher education, and general outreach communities. Current programs focus on Solar System exploration missions such as the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Miniature Radio Frequency (Mini-RF) Moon explorer, the Radiation Belt Storm Probes (RBSP), New Horizons mission to Pluto, and the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) Satellite, to name a few. Education and outreach programs focusing on K-12 formal education include visits to classrooms, summer programs for middle school students, and teacher workshops. APL hosts a Girl Power event and a STEM (Science, Technology, Engineering, and Mathematics) Day each year. Education and outreach specialists hold teacher workshops throughout the year to train educators in using NASA spacecraft science in their lesson plans. High school students from around the U.S. are able to engage in NASA spacecraft science directly by participating in the Mars Exploration Student Data Teams (MESDT) and the Student Principal Investigator Programs. An effort is also made to generate excitement for future missions by focusing on what mysteries will be solved. Higher education programs are used to recruit and train the next generation of scientists and engineers. The NASA/APL Summer Internship Program offers a unique glimpse into the Space Department’s “end-to-end” approach to mission design and execution. College students - both undergraduate and graduate - are recruited from around the U.S. to work with APL scientists and engineers who act as mentors to the students. Many students are put on summer projects that allow them to work with existing spacecraft systems, while others participate in projects that investigate the operational and science objectives of future planned spacecraft systems. In many cases these interns have returned to APL as full-time staff after graduation.

    The Space Weather Around the World Program uses NASA satellite data and education technology to provide a framework for students and teachers to study the effects of solar storms on the Earth and then report their results at their own school and to others around the world. Teachers and students are trained to create Space Weather Action Centers by building their own equipment to take data or using real satellite and/or ground-based data available through the internet to study and track the effects of solar storms. They can then predict "space weather" for our planet and what the effects might be on aurora, Earth-orbiting satellites, humans in space, etc. The results are presented via proven education technology techniques including weather broadcasts using green screen technology, podcasts, webcasts and distance learning events. Any one of these techniques can capture the attention of the audience, engage them in the science and spark an interest that will encourage continued participation. Space Weather Around the World uses all of these techniques to engage millions. We will share the techniques that can be applied to any subject area and will increase participation and interest in that content. The Space Weather program provides students and teachers with unique and compelling teaching and learning experiences that will help to improve science literacy, spark an interest in careers in Science, Technology, Engineeering, and Mathematics (STEM), and engage children and adults in shaping and sharing the experience of discovery and exploration.

    In addition to supporting space research in the international community, the Community Coordinated Modeling Center (CCMC) has as its second objective to bring to apply the power of modern research models toward space weather specification and forecasting. Initially motivated by the objective to test models and to ease the transition of research models to space weather forecasting organization, the CCMC has developed a number of real-time modeling systems, as well as large number of modeling and data products for space weather forecasting. Over time, these activities have evolved into tailored products for partners, as well as into a direct support of the space weather needs within NASA robotic mission community. Accessible through a customizable interface, users within the US or at partnering institutions internationally have access to space weather tools driven by the most advanced space research models. Through partnering with agencies and institutions in the US and abroad, the CCMC strives to set up further data sharing agreements to the benefit of all participating institutions. In this presentation, we provide an overview of existing CCMC space weather services and products, and we will explore additional avenues for international collaborations.

  5. The space of phylogenetic mixtures for equivariant models

    PubMed Central

    2012-01-01

    Background The selection of an evolutionary model to best fit given molecular data is usually a heuristic choice. In his seminal book, J. Felsenstein suggested that certain linear equations satisfied by the expected probabilities of patterns observed at the leaves of a phylogenetic tree could be used for model selection. It remained an open question, however, whether these equations were sufficient to fully characterize the evolutionary model under consideration. Results Here we prove that, for most equivariant models of evolution, the space of distributions satisfying these linear equations coincides with the space of distributions arising from mixtures of trees. In other words, we prove that the evolution of an observed multiple sequence alignment can be modeled by a mixture of phylogenetic trees under an equivariant evolutionary model if and only if the distribution of patterns at its columns satisfies the linear equations mentioned above. Moreover, we provide a set of linearly independent equations defining this space of phylogenetic mixtures for each equivariant model and for any number of taxa. Lastly, we use these results to perform a study of identifiability of phylogenetic mixtures. Conclusions The space of phylogenetic mixtures under equivariant models is a linear space that fully characterizes the evolutionary model. We provide an explicit algorithm to obtain the equations defining these spaces for a number of models and taxa. Its implementation has proved to be a powerful tool for model selection. PMID:23190710

  6. IHY activities in West Asia: Research and Education in Astronomy and Space Sciences for Arab Countries

    NASA Astrophysics Data System (ADS)

    Al-Naimiy, H. M. K.

    2006-11-01

    alnaimiy2@yahoo.com Astronomy and Space Sciences (ASS) are important fields of research, study, knowledge and culture. They have been the cradle of both eastern and western sciences. We all know, from education and psychology, about the effective teaching and learning of ASS. Unfortunately, a small percentage of this knowledge is actually used in teaching at schools, universities level and any other academic institutions in the Arab countries. The challenge is to provide effective professional development for ASS educators and researchers at all levels, from elementary school to university. ASS is the most appealing subject to young students and very important tool to convey scientific knowledge? Once students have understood the importance of science, they might be more easily pursued to continue their education in science and technology. The aim of this paper is to show the importance of the formal and informal ASS research, and education, giving an example of a possible curriculum, projects, and comments on the activities that have been carried out in a few Arab countries. We feel the need for a new communication channel among the Arab people based on our common scientific ground. ASS is, in this respect, the best possible choice in the vast cultural heritage of the Arab basin. The final purpose is scientific and economical. Building modern and good observatories, planetariums and research centers in the region jointly by Arab astronomers and space scientists is essential and will be an excellent step toward developing astronomy and astrophysics (for research, education and knowledge).

    Parametric cost models are routinely used to plan missions, compare concepts, and justify technology investments. Unfortunately, there is no definitive space telescope cost model. For example, historical cost estimating relationships (CERs) based on primary mirror diameter vary by an order of magnitude. We present new single-variable cost models for space telescope optical telescope assembly (OTA). They are based on data collected from 30 different space telescope missions. Standard statistical methods are used to derive CERs for OTA cost versus aperture diameter and mass. The results are compared with previously published models

    Capacity-building efforts in space science and technology are a major focus of the activities of the Office of Outer Space Affairs. Such efforts include providing support to the regional centres for space science and technology education, affiliated to the United Nations, whose goal is to develop, through in-depth education, an indigenous capability for research and applications in the core disciplines of: (a) remote sensing and geographical information systems; (b) satellite communications; (c) satellite meteorology and global climate; and (d) space and atmospheric sciences and data management. The regional centres are located in Morocco and Nigeria for Africa, in Brazil and Mexico for Latin America and the Caribbean and in India for Asia and the Pacific. The overall policy-making body of each Centre is its Governing Board and consists of member States (within the region where the Centre is located), that have agreed, through their endorsement of the Centre's agreement, to the goals and objectives of the Centre. The United Nations Programme on Space Applications, with the support of prominent educators, has developed standard education curricula, which were adopted by the Centres for teaching each of the four core disciplines. Within the framework of the International Committee on global navigation satellite systems (ICG), which is established as an informal body for the purpose of promoting the use and application of global navigation satellite systems (GNSS) on a global basis, the Regional Centres will also be acting as the ICG Information Centres. The ICG Information Centres aim to foster a more structured approach to information exchange in order to fulfil the reciprocal expectations of a network between ICG and Regional Centres.

    The baseline Space Station Freedom electric power system (EPS) employs photovoltaic (PV) arrays and nickel hydrogen (NiH2) batteries to supply power to housekeeping and user electrical loads via a direct current (dc) distribution system. The EPS was originally designed for an operating life of 30 years through orbital replacement of components. As the design and development of the EPS continues, accurate EPS performance predictions are needed to assess design options, operating scenarios, and resource allocations. To meet these needs, NASA Lewis Research Center (LeRC) has, over a 10 year period, developed SPACE (Station Power Analysis for Capability Evaluation), a computer code designed to predict EPS performance. This paper describes SPACE, its functionality, and its capabilities.

  10. A Prototype for Education Programs using Planetari and Space Centres as Key Tools

    NASA Astrophysics Data System (ADS)

    Thompson, L; Brumfitt, A.; Honan, P.

    Few hands on space experiments designed for school education allow the students and teachers to participate in the discovery of new science. One particularly experiment which flew on STS107 Columbia was designed specifically to do just this. A key feature of the project was to use a Zoo and a University as key tools in providing through life development and support. The project, "Spiders in Space" ran over a four year period resulted in the student and scientist team publishing over twenty refereed papers on their research findings. Throughout the project teacher and student performance, satisfaction, knowledge, abilities and competency were monitored and critically evaluated. The progressive gathering and feedback was used to improve the program and adapt the learning experience to the student needs and abilities. Based on the experience gained with the Spider Experiment on STS-107, the originating team of scientists and teachers have formulated a structure on which to facilitate the design of similar space education cross discipline projects. The project architecture presented uses as key tools Planetaria, Space science education centres, zoos and Universities in the successful delivery of the programs.The engagement of these key tools facilitates a cost effective and educationally sound support network for thousands of schools to have some ownership of their space program. These key tools provide both continuing professional development for teachers wishing to enter the program and field laboratory support for the student classes engaged in it. The resulting programs are designed to foster collaboration between space research and education on an international scale. The sample new program is presented which demonstrates the application of scientific principles by making students and teachers an integral part of current space research. Issues such as environment, climate control and biological diversity are investigated with a view to providing research outcomes in support of the European Aurora Program, the first human mission to Mars. The cross disciplinary nature of the program encourages participation from all students and promotes a team approach. The investigation incorporates topics covered in Physics, Chemistry and Biology within the current secondary school curriculum and integrates them with Economics, Construction, Project Management and International Relations.

  11. 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 Vlasov description of plasma is carried out using the Vlasiator model. The test shows that the Vlasov equation for plasma in six-dimensionsional phase space is solved correctly b! y Vlasiator, that results are obtained beyond those of the magnetohydrodynamic (MHD) description of plasma and that global magnetospheric simulations using a hybrid-Vlasov model are feasible on current hardware. For the first time four global magnetospheric models using the MHD description of plasma (BATS-R-US, GUMICS, OpenGGCM, LFM) are run with identical solar wind input and the results compared to observations in the ionosphere and outer magnetosphere. Based on the results of the global magnetospheric MHD model GUMICS a hypothesis is formulated for a new mechanism of plasmoid formation in the Earth's magnetotail.

    Space education is a discipline that has evolved at an unprecedented rate over the past 25 years. Although program proceedings, research literature, and historical documentation have captured fragmented pieces of information about student space experiments, the field lacks a valid comprehensive study that measures the educational impact of sounding rockets, Skylab, Ariane, AMSAT, and Space Shuttle. The lack of this information is a problem for space educators worldwide which led to a national study with classroom teachers. Student flown experiments continue to offer a unique experiential approach to teach students thinking and reasoning skills that are imperative in the current international competitive environment in which they live and will work. Understanding the history as well as the current status and educational spin-offs of these experimental programs strengthens the teaching capacity of educators throughout the world to develop problem solving skills and various higher mental processes in the schools. These skills and processes enable students to use their knowledge more effectively and efficiently long after they leave the classroom. This paper focuses on student space experiments as a means of motivating students to meet this educational goal successfully. PMID:11541156

    If you go to the country, far from city lights, you can see about 3,000 stars on a clear night. If your eyes were bigger, you could see many more stars. With a pair of binoculars, an optical device that effectively enlarges the pupil of your eye by about 30 times, the number of stars you can see increases to the tens of thousands. With a medium-sized telescope with a light-collecting mirror 30 centimeters in diameter, you can see hundreds of thousands of stars. With a large observatory telescope, millions of stars become visible. This curriculum guide uses hands-on activities to help students and teachers understand the significance of space-based astronomy--astronomical observations made from outer space. It is not intended to serve as a curriculum. Instead, teachers should select activities from this guide that support and extend existing study. The guide contains few of the traditional activities found in many astronomy guides such as constellation studies, lunar phases, and planetary orbits. It tells, rather, the story of why it is important to observe celestial objects from outer space and how to study the entire electromagnetic spectrum. Teachers are encouraged to adapt these activities for the particular needs of their students. When selected activities from this guide are used in conjunction with traditional astronomy curricula, students benefit from a more complete experience.

  6. Thermal modeling, analysis and control of a space suit

    NASA Astrophysics Data System (ADS)

    Campbell, Anthony Bruce

    The thermal dynamics of two space suits, the Space Shuttle EMU and the MPLSS Advanced Space Suit, are considered as they relate to astronaut thermal comfort control. The activities documented in this dissertation cover three related areas, modeling, analysis, and control. A detailed dynamic lumped capacitance thermal model of the operational Space Shuttle EMU is used to analyze the thermal dynamics of the system with observations verified using experimental and flight data. Prior to using the model to define performance characteristics and limitations for the space suit, the model is first evaluated and improved. This evaluation includes determining the effect of various model parameters on model performance and quantifying various temperature prediction errors in terms of heat transfer and heat storage. The thermal dynamics and design of an Advanced Space Suit are next considered. A transient model of the MPLSS Advanced Space Suit design is developed and implemented using MATLAB/Simulink, to help with sizing, with design evaluation, and with the development of an automatic thermal comfort control strategy. The model is described and the thermal characteristics of the Advanced Space Suit are investigated including various parametric design studies. The steady state performance envelope for the Advanced Space Suit is defined in terms of the thermal environment and human metabolic rate and the transient response of the human-suit-MPLSS system is analyzed. The observations and insights about the thermal dynamics of a space suit are then applied to the automatic thermal comfort control of the MPLSS Advanced Space Suit. Automatic thermal comfort control for the Advanced Space Suit is investigated using three proposed strategies. These strategies use a transient thermal comfort definition based on body heat storage. The first strategy is measurement based using a proposed body heat storage estimation method to determine the astronaut's thermal state. The second strategy is model based using a model to determine the desired liquid cooling garment inlet temperature to provide thermal comfort. The third strategy is a hybrid strategy combining the measurement based and model based approach using the Generalized Predictive Control framework. Each strategy then uses a resource allocation decision logic to determine which of three control mechanisms to use so that thermal comfort can be provided while minimizing the use of consumables. Accuracy and performance of the strategies are evaluated using simulations, highlighting their advantages and limitations.

    Earth's ionosphere reacts strongly to the intense x-ray and ultraviolet radiation released by the Sun during solar events and by lightning during thunderstorms. Students around the world can directly monitor and track these sudden ionospheric disturbances (SIDs) by using a receiver to monitor the signal strength from distant VLF transmitters, and noting unusual changes as the waves bounce off the ionosphere. Stanford's Solar Center, in conjunction with the Space, Telecommunications and Radioscience Laboratory and local educators, have developed inexpensive ionospheric disturbance monitors that students can install and use at their local schools. Students "buy in" to the project by building their own antenna, a simple structure costing little and taking a couple hours to assemble. Data collection and analysis is handled by a local PC. Stanford is providing a centralized data repository where students can exchange and discuss data. Two versions of the monitors exist -- a low-cost version (nicknamed "SID") designed to detect solar flares, and a more sensitive version ("AWESOME") that provides both solar and nighttime research-quality data. Both monitors are currently being placed in high schools and community colleges around the US. Students will have the opportunity to work with a researcher "mentor" to collect and interpret data. Our space weather monitors have been chosen as educational and small intruments projects for deployment to 191 countries around the world for the International Heliophysical Year, 2007. Our presentation will focus on the educational aspects of the Space Weather Monitor program.

    The INSPIRE program at Mississippi State University (MSU), funded by the NSF Graduate STEM Fellows in K-12 Education (GK12) program, focuses on Earth and Space science education and has partnered ten graduate students from MSU with five teachers from local, rural school districts. For the next five years the project will serve to increase inquiry and technology experiences in science and math while enhancing graduate student’s communication skills. Graduate students, from the disciplines of Geosciences, Physics, and Engineering are partnered with Chemistry, Physical Science, Physics, Geometry and Middle school science classrooms and will create engaging inquiry activities that incorporate elements of their research, and integrate various forms of technology. The generated lesson plans that are implemented in the classroom are published on the INSPIRE home page (www.gk12.msstate.edu) so that other classroom instructors can utilize this free resource. Local 7th -12th grade students will attend GIS day later this fall at MSU to increase their understanding and interest in Earth and Space sciences. Selected graduate students and teachers will visit one of four international university partners located in Poland, Australia, England, or The Bahamas to engage research abroad. Upon return they will incorporate their global experiences into their local classrooms. Planning for the project included many factors important to the success of the partnerships. The need for the program was evident in Mississippi K-12 schools based on low performance on high stakes assessments and lack of curriculum in the Earth and Space sciences. Meeting with administrators to determine what needs they would like addressed by the project and recognizing the individual differences among the schools were integral components to tailoring project goals and to meet the unique needs of each school partner. Time for training and team building of INSPIRE teachers and graduate students before the school year aided in fostering a community atmosphere to ensure successful classroom experiences. Including stakeholders in the progress of lesson plan product development during a workshop luncheon was another key part to building a community of support for INSPIRE. These planning components are essential to the success of the project and are recommended to similar projects. The INSPIRE project external evaluation includes: (i) interviews of participants and K-12 students involved in INSPIRE, (ii) pre-post technology and teaching attitude surveys of graduate students and teachers, (iii) thematic analysis of daily feedback forms from the workshop, (iv) summary of end of workshop evaluations, and (v) constant surveying of program progress towards meeting its goals. Internal evaluation includes: (i) classroom observations of graduate student interactions with students (ii) bi-weekly journal entries from both teachers and graduate students, and (iii) weekly feedback from graduate students. Preliminary evaluation of the workshop daily feedback forms indicate a high level of approval for the technology and inquiry activities modeled. Journal entries indicate that the majority of Fellow-teacher teams experience positive interactions in the classroom.

    Development and support of community-based, interdisciplinary ambulatory medical education has achieved high priority due to on-site capacity and the unique educational experiences community sites contribute to the educational program. The authors describe the collaborative model their school developed and implemented in 2000 to integrate institution- and community-based interdisciplinary education through a centralized office, the strengths and challenges faced in applying it, the educational outcomes that are being tracked to evaluate its effectiveness, and estimates of funds needed to ensure its success. Core funding of $180,000 is available annually for a centralized office, the keystone of the model described here. With this funding, the office has (1) addressed recruitment, retention, and quality of educators for UME; (2) promoted innovation in education, evaluation, and research; (3) supported development of a comprehensive curriculum for medical school education; and (4) monitored the effectiveness of community-based education programs by tracking product yield and cost estimates needed to generate these programs. The model's Teaching and Learning Database contains information about more than 1,500 educational placements at 165 ambulatory teaching sites (80% in northern New England) involving 320 active preceptors. The centralized office facilitated 36 site visits, 22% of which were interdisciplinary, involving 122 preceptors. A total of 98 follow-up requests by community-based preceptors were fulfilled in 2000. The current submission-to-funding ratio for educational grants is 56%. Costs per educational activity have ranged from $811.50 to $1,938, with costs per preceptor ranging from $101.40 to $217.82. Cost per product (grants, manuscripts, presentations) in research and academic scholarship activities was $2,492.

    This paper reports on educational activities supported by the IDEAS program in the Washington, DC area. Here, we discuss activities which have been in progress over the last 5 years, which include the following: (1) development of a series of videos in space science, and associated "hands-on" activities, intended for pre-college students as supplements to their classroom education; (2) a summer teacher-training course, along the same topic outlines as (1); and (3) direct involvement of students in space science research at the Naval Research Laboratory and at Howard University's on-campus observatory. We have completed 5 chapters, with a total run time of more than 9 hours, of our proposed "Pyramids to Planets" video series in Earth and Space Science (totalling 16 chapters, of which only the space science portions are funded by IDEAS). We also plan a "stand-alone" video, "From Earth to Mars", which is a documentary of a crewed mission to Mars and return, using student "actors", which utilizes and conveys only factual information and realistic proposals for such a mission. We presented a 2-week, full-time course of study in Earth & Space Science for DC Public Schools science teachers during the summers of 1996 and 1997 (co-sponsored by the DC Space Grant Consortium). This course also introduced the teachers to the "hands-on" activities demonstrated by students in the videos. Students are directly involved, via after-school programs and summer internships, in space science activities at NRL. These include pre-launch instrument development and testing, post-launch data analysis, and education/public outreach activities for the Advanced Research and Global Observation Satellite (ARGOS) launched February 23, 1999. Students also participated in the development of two spectrographs planned for use on an existing telescope at Howard University's on-campus observatory. The facilities at this observatory are being made available for pre-college student and public use, as well as for on-campus students and staff. (This activity is also co-sponsored by the DC Space Grant Consortium.)

    In this paper, random matrix models with a line as a target space are considered. The models are a natural generalization of the Hermitian matrix model and connected with the classical symmetric spaces of the Euclidean type which were classified by Cartan. Ten different types of these spaces exist. Three models on a line related to these models are reduced to one-dimensional free N-fermion problems which have special symmetric configurations. The solutions in the double scaling limit to all orders of perturbation are the same as for the Hermitian matrix model. In the general case the fermions interact with the Calogero-Mozer integrable potential. Due to this fact only the planar limit can be calculated by applying the Hartree-Fock approximation procedure.

    The floating potential of the International Space Station (ISS) as a function of the electron current collection of its high voltage solar array panels is derived analytically. Based on Floating Potential Probe (FPP) measurements of the ISS potential and ambient plasma characteristics, it is shown that the ISS floating potential is a strong function of the electron temperature of the surrounding plasma. While the ISS floating potential has so far not attained the pre-flight predicted highly negative values, it is shown that for future mission builds, ISS must continue to provide two-fault tolerant arc-hazard protection for astronauts on EVA.

  10. A regressive storm model for extreme space weather

    NASA Astrophysics Data System (ADS)

    Terkildsen, Michael; Steward, Graham; Neudegg, Dave; Marshall, Richard

    2012-07-01

    Extreme space weather events, while rare, pose significant risk to society in the form of impacts on critical infrastructure such as power grids, and the disruption of high end technological systems such as satellites and precision navigation and timing systems. There has been an increased focus on modelling the effects of extreme space weather, as well as improving the ability of space weather forecast centres to identify, with sufficient lead time, solar activity with the potential to produce extreme events. This paper describes the development of a data-based model for predicting the occurrence of extreme space weather events from solar observation. The motivation for this work was to develop a tool to assist space weather forecasters in early identification of solar activity conditions with the potential to produce extreme space weather, and with sufficient lead time to notify relevant customer groups. Data-based modelling techniques were used to construct the model, and an extensive archive of solar observation data used to train, optimise and test the model. The optimisation of the base model aimed to eliminate false negatives (missed events) at the expense of a tolerable increase in false positives, under the assumption of an iterative improvement in forecast accuracy during progression of the solar disturbance, as subsequent data becomes available.

    2000-01-01

    This proposal addresses the need for effective and innovative science and health education materials that focus on space bone biology and its implications for bone health on Earth. The focus of these materials, bone biology and health, will increase science knowledge as well as health awareness. Current investigations of the bone loss observed after long-duration space missions provide a link between studies of bone health in space, and studies of osteoporosis, a disease characterized by bone loss and progressive skeletal weakness. The overall goal of this project is to design and develop web-based and print-based materials for high school science students, that will address the following: a) knowledge of normal bone biology and bone biology in a microgravity environment; b) knowledge of osteoporosis; c) knowledge of treatment modalities for space- and Earth-based bone loss; and d} bone-related nutrition knowledge and behavior. To this end, we propose to design and develop a Bone Biology Tutorial which will instruct students about normal bone biology, bone biology in a microgravity environment, osteoporosis - its definition, detection, risk factors, and prevention, treatment modalities for space- and Earth-based bone loss, and the importance of nutrition in bone health. Particular emphasis will be placed on current trends in . adolescent nutrition, and their relationships to bone health. Additionally, we propose to design and develop two interactive nutrition/health ' education activities that will allow students to apply the information provided in the Bone Biology Tutorial. In the first, students will apply constructs provided in the Bone Biology Tutorial to design "Bone Health Plans" for space travelers.

  16. Radiation dosimetry and biophysical models of space radiation effects

    NASA Technical Reports Server (NTRS)

    Cucinotta, Francis A.; Wu, Honglu; Shavers, Mark R.; George, Kerry

    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.

    The Community Coordinated Modeling center (CCMC) is a multi-agency partnership to support the research and developmental work necessary to substantially increase space weather modeling capabilities and to facilitate advanced models deployment in forecasting operations. The CCMC conducts unbiased model testing and validation and evaluates model readiness for operational environment. Space weather models and coupled model chains hosted at the CCMC range from the solar corona to the Earth's upper atmosphere. CCMC has developed a number of real-time modeling systems, as well as a large number of modeling and data products tailored to address the space weather needs of NASA's robotic missions. The presentation will demonstrate the rapid progress towards development the system allowing using products derived from space weather models in applications associated with National Space Weather needs. The adaptable Integrated Space Weather Analysis (ISWA) System developed at CCMC for NASA-relevant space weather information combines forecasts based on advanced space weather models hosted at CCMC with concurrent space environment information. The system is also enabling post-impact analysis and flexible dissemination of space weather information.

  1. Meaningful experiences in science education: Engaging the space researcher in a cultural transformation to greater science literacy

    NASA Technical Reports Server (NTRS)

    Morrow, Cherilynn A.

    1993-01-01

    The visceral appeal of space science and exploration is a very powerful emotional connection to a very large and diverse collection of people, most of whom have little or no perspective about what it means to do science and engineering. Therein lies the potential of space for a substantially enhanced positive impact on culture through education. This essay suggests that through engaging more of the space research and development community in enabling unique and 'meaningful educational experiences' for educators and students at the pre-collegiate levels, space science and exploration can amplify its positive feedback on society and act as an important medium for cultural transformation to greater science literacy. I discuss the impact of space achievements on people and define what is meant by a 'meaningful educational experience,' all of which points to the need for educators and students to be closer to the practice of real science. I offer descriptions of two nascent science education programs associated with NASA which have the needed characteristics for providing meaningful experiences that can cultivate greater science literacy. Expansion of these efforts and others like it will be needed to have the desired impact on culture, but I suggest that the potential for the needed resources is there in the scientific research communities. A society in which more people appreciate and understand science and science methods would be especially conducive to human progress in space and on Earth.

    1999-01-01

    The outreach and education components of the International Space Station Program are creating a number of materials, programs, and activities that educate and inform various groups as to the implementation and purposes of the International Space Station. One of the strategies for disseminating this information to K-12 students involves an electronic class room using state of the art video conferencing technology. K-12 classrooms are able to visit the JSC, via an electronic field trip. Students interact with outreach personnel as they are taken on a tour of ISS mockups. Currently these events can be generally characterized as: Being limited to a one shot events, providing only one opportunity for students to view the ISS mockups; Using a "one to many" mode of communications; Using a transmissive, lecture based method of presenting information; Having student interactions limited to Q&A during the live event; Making limited use of media; and Lacking any formal, performance based, demonstration of learning on the part of students. My project involved developing interactive lessons for K-12 students (specifically 7th grade) that will reflect a 2nd generation design for electronic field trips. The goal of this design will be to create electronic field trips that will: Conform to national education standards; More fully utilize existing information resources; Integrate media into field trip presentations; Make support media accessible to both presenters and students; Challenge students to actively participate in field trip related activities; and Provide students with opportunities to demonstrate learning

  6. (De)constructing literacy: Education inequalities and the production of space in San Diego, California

    NASA Astrophysics Data System (ADS)

    Tangeman, Andrew Gerrit

    Since its inception, the No Child Left Behind Act of 2001 (NCLB) and recent additions to the U.S. Elementary and Secondary Education Act (ESEA) have elicited a broad swath of responses from the educational community. These responses include critical discussions of how standardized testing requirements proliferate a "teach for the test" mentality that transforms how reading, writing, and mathematics are taught in public schools. This thesis focused specifically on "literacy" in relation to the policies that challenge its status as a subjective form of communication, knowledge sharing, and story-telling. Embedded within the term "literacy" are sets of socially-constructed dualisms such as "good school" vs. "bad school," "literate" vs. "illiterate," and "reader" vs. "test-taker" that are propagated under education reform. Investigating these dualisms involved a mixed methods approach, which included the use of critical theory, geovisualization, and geographic analysis. The resulting data allows for a comprehensive look into the economic, political, social, and cultural forces involved in the production of literate space(s) in San Diego, California.

  7. Van Allen Probes Mission Space Academy: Educating middle school students about Earth's mysterious radiation belts

    NASA Astrophysics Data System (ADS)

    Butler, L.; Turney, D.; Matiella Novak, A.; Smith, D.; Simon, M.

    2013-12-01

    How's the weather in space? Why on Earth did NASA send two satellites above Earth to study radiation belts and space weather? To learn the answer to questions about NASA's Van Allen Probes mission, 450 students and their teachers from Maryland middle schools attended Space Academy events highlighting the Van Allen Probes mission. Sponsored by the Applied Physics Laboratory (APL) and Discovery Education, the events are held at the APL campus in Laurel, MD. Space Academies take students and teachers on behind-the-scenes exploration of how spacecraft are built, what they are designed to study, and introduces them to the many professionals that work together to create some of NASA's most exciting projects. Moderated by a public relations representative in the format of an official NASA press conference, the daylong event includes a student press conference with students as reporters and mission experts as panelists. Lunch with mission team members gives students a chance to ask more questions. After lunch, students don souvenir clean room suits, enjoy interactive science demonstrations, and tour APL facilities where the Van Allen Probes were built and tested before launch. Students may even have an opportunity to peek inside a clean room to view spacecraft being assembled. Prior to the event, teachers are provided with classroom activities, lesson plans, and videos developed by APL and Discovery Education to help prepare students for the featured mission. The activities are aligned to National Science Education Standards and appropriate for use in the classroom. Following their visit, student journalists are encouraged to write a short article about their field trip; selections are posted on the Space Academy web site. Designed to engage, inspire, and influence attitudes about space science and STEM careers, Space Academies provide an opportunity to attract underserved populations and emphasize that space science is for everyone. Exposing students to a diverse group of scientists and engineers may alleviate some common stereotypes about these careers. When students engage with the scientists and engineers at APL, they see first-hand that successful science and engineering requires a diverse team with multi-disciplinary backgrounds. Activities throughout the day develop student understanding about science and technology, and address the fundamental concepts that fall under the National Science Education Content Standards. Students are immersed in a hands-on experience designed to facilitate understanding of the History and Nature of Science. Throughout the day students interact with people of diverse backgrounds and interests while hearing about the specific ways various individuals and teams of people contribute to the science and technology of the mission, addressing the concepts which fall under the headings of Science as a Human Endeavor, Nature of Science, and History of Science. Getting students outside the classroom to visit APL is an exclusive opportunity; evaluations have indicated that students became interested in learning more about space science and STEM careers after attending a Space Academy event.

    2012-04-01

    Tomorrow's classroom may not be a classroom. In fact, it may not be a room at all. With a recent focus on summer learning and the understanding that much of the achievement gap may be directly related to "unequal access to summer learning opportunities" (National Summer Learning Association, 2011 & Russo, 2011), educators are targeting after-school and summer-times to fill the gap. For those students who "don't get it" during the day, a longer school day may not be the solution. More of the same is not always better. Different, on the other hand, may well be the key to improved learning and may drive the model of education in the future. The nature of this investigation was to identify those informal education programs at NASA Goddard Space Flight Center (Greenbelt, Maryland USA) that instilled inspiration and engagement in participants. During 2011, NASA Goddard Space Flight Center hosted two such programs and supported a third: an open house event for the general public, a museum educators' workshop, and NASA's BEST Students (NBS) educator professional development at the Los Angeles, California Unified School District (LAUSD) "Beyond the Bell" after-school program. Each was a unique experience. The open house drew approximately 15,000 with over 4,000 taking part in structured informal educational programs, the workshop supported 30 informal educators from museums across the United States, and NBS hosted 33 after-school coach-educators from LAUSD. Formative evaluation of these programs was carried out and preliminary results indicate high levels of engagement, desire for follow-on learning, and interest in additional hands-on and partnership opportunities. Each event enjoyed positive reviews and each served to further deploy high-quality NASA STEM content to learners. This work was first presented at the American Geophysical Union 2011 Fall Meeting in San Francisco, California. Since then, additional museum educators' workshop data has been collected and NBS has been added.

    A pose acquisition system operating in space must be able to perform well in a variety of different applications including automated guidance and inspections tasks with many different, but known objects. Since the space station is being designed with automation in mind, there will be CAD models of all the objects, including the station itself. The construction of vision models and procedures directly from the CAD models is the goal of this project. The system that is being designed and implementing must convert CAD models to vision models, predict visible features from a given view point from the vision models, construct view classes representing views of the objects, and use the view class model thus derived to rapidly determine the pose of the object from single images and/or stereo pairs.

    Astronomy educators present the range of astronomy education programming available at the National Air and Space Museum, including the following. In the Phoebe Waterman Haas Public Observatory, visitors use telescopes and other scientific equipment to observe and discuss the Sun, Venus, and other celestial sights in an unstructured, inquiry-based environment. At Discovery Stations throughout the Museum, staff and volunteers engage visitors in hands-on exploration of a wide range of artifacts and teaching materials. Astronomy-related Discovery Stations include Cosmic Survey, an exploration of gravitational lensing using a rubber sheet, spectroscopy using discharge tubes, and several others. Astronomy lectures in the planetarium or IMAX theater, featuring researchers as the speakers, include a full evening of activities: a custom pre-lecture Discovery Station, a handout to help visitors explore the topic in more depth, and evening stargazing at the Public Observatory. Astronomy educators present planetarium shows, including star tours and explorations of recent science news. During Astronomy Chat, an astronomy researcher engages visitors in an informal conversation about science. The goal is to make the public feel welcome in the environment of professional research and to give busy scientists a convenient outreach opportunity. Astronomy educators also recruit, train, and coordinate a corps of volunteers who contribute their efforts to the programming above. The volunteer program has grown significantly since the Public Observatory was built in 2009.

    Since its inception in 1999, the EPO office of the MIT Center for Space Research (CSR) has fostered direct participation of local scientists in educational initiatives such as teachers workshops and public tours of the Chandra Operations and Control Center. The role played by the CSR EPO office has grown significantly, thanks to the award of a number of EPO grants associated with the Chandra and HETE missions. In the past year about one-third of the CSR research staff was involved in the office's EPO initiatives: more than 500 K-12 students, about half from underrepresented groups, were included in formal education programs and informal education events attracted an estimated 900 people. Today the mission of the CSR EPO office is focused in two areas: professional development for K-12 science teachers, and educational programs in out-of-school time. To be associated with major NASA research missions is beneficial to our mission in several respects, but provides also specific challenges. We present here some of the strategies and intiatives that we have undertaken to overcome those challenges.

    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. PMID:11317721

    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

    Secondary aluminum production (melting from aluminum ingots, scraps, etc.) offers significant energy savings and environmental benefits over primary aluminum production since the former consumes only five percent of the energy used in the latter process. The industry, however, faces technical challenges of further improving furnace melting efficiency and has been lacking tools that can help understand combustion process in detail and that will facilitate furnace design. Computational Fluid Dynamics (CFD) modeling has played increasingly important roles in evaluating industrial processes. As part of a larger program run by SECAT, a CFD model has been developed at Argonne National Laboratory to simulate fuel combustion, heat transfer (including thermal radiation), gaseous product flow (mainly CO2 and H2O), and production/transport of pollutant species/greenhouse gases in an aluminum furnace. Using this code, the surface heat fluxes are calculated and then transferred to a melt code. In order to have a high level of confidence in the computed results, the output from the code will be compared and validated against in-furnace measurements made in the Albany furnace. Once validated, the combustion code may be used to perform inexpensive parametric studies to investigate methods to optimize furnace performance. This paper will present results from the combustion modeling of an aluminum furnace as well as results from several parametric studies.

    This paper presents the main practical aspects regarding the organization of a summer school in the field of Space Technologies and Radio Science. This one-week summer school is aimed for education of teenagers between 12 and 16 years. Currently, the summer school reached its third edition. During this educational activities some especially designed prototype equipments were used with the main purpose of educating adolescents towards a scientific career in the field of Space Technologies and Radio Science. The main equipments and associated experiments are presented as follows: 1. A teaching purpose radio telescope emphasizing the working principle of professional radio telescopes. The experiments were focused on scanning the sky for identifying the positions of geostationary satellites and the Sun. 2. A weather satellite reception equipment used for downloading real-time APT (Automatic Picture Transmission) weather data from NOAA (National Oceanic and Atmospheric Administration) weather satellite fleet. The visual images were used for emphasizing the clouds and cloud systems over Europe. 3. A prototype equipment for receiving electromagnetic waves in the field of VLF (Very Low Frequency) with the purpose of analyzing the electromagnetic radio frequency spectrum. The main emphasized phenomenons in the VLF band (3 kHz - 30 kHz) are related to radio transmitters, electrical discharges in the atmosphere (lightning) and the electromagnetic pollution. 4. An equipment designed for initiating teenagers in the field of radio communication. This equipment was used for transmission and reception of images and sound over a distance of few kilometers, by using high-gain directional antennas. 5. Other sets of experiments were undertaken with the main purpose of mapping the countryside area in which the experiments had taken place. For this activity GPS devices were used. This paper may be considered a practical guideline for those who want to attract young students towards a scientific carrier. This is a new approach of educating teenagers in the field of STEM (Science, Technology, Engineering and Mathematics).

  12. Observations and Modeling of Space Weather Impacts on the Earth

    2006-10-01

    ``Space weather'' refers to conditions in the solar wind, magnetosphere, ionosphere, and upper atmosphere, that influence space-borne and ground-based technological systems and can endanger human space exploration. These effects are caused by variations in solar photon and particle radiation due to flares and coronal mass ejections, and changes in the solar/interplanetary magnetic field, that impact the magnetosphere and ionosphere. Space weather can initiate satellite failures, interfere with radio communications, cause navigation errors, disrupt electrical power distribution systems, and expose astronauts to dangerous levels of radiation. Mitigation requires both a better understanding of the space environment, and developing the ability to forecast conditions in space. The development of first-principles numerical models of the solar-terrestrial system gives us insight into the causes and nature of these phenomena, and holds the promise of ultimately being able to acquire a short-term predictive capability for some of them. This presentation will describe what we do and don't understand about the basic physics behind space weather, discuss some of its aspects and effects, and describe the latest observational and modeling efforts

    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.

  16. Narratively Speaking: Oscillating in the Liminal Space of Science Education Between Two Worlds

    2011-12-01

    Aboriginal success in the sciences is rare and as a consequent result there is little Aboriginal representation in science related-disciplines such as medicine, nursing, science education and scientific research to name a few. The Western academic system has historically been unfriendly to Aboriginal people with little understanding of Aboriginal Ways-of-Knowing and learning and as a result many Aboriginal people struggle academically in trying to bridge Aboriginal to Western ways-of-knowing and learning. But some have succeeded while maintaining their cultural identity, in spite of the odds. This research examines Aboriginal success at post-secondary education, specifically the ways in which those who succeeded did when so many have not. The narratives of experience of Aboriginal women and men from Manitoba, Saskatchewan and Alberta, who have journeyed through post-secondary education, with a specific although not an entire, focus on the sciences were collected. Additionally the narratives of those who left, as well as those who are currently on their academic journey, were collected. Through narrative analysis, it was found those who did succeed were able to see the space between the two opposing paradigms, Western and Aboriginal, as a space of possibility, a liminal space, rather than as a gap of deficiency. They had a dream or a vision of a different life, the will or inner strength to get the skills while at the same time maintaining their cultural identity and integrity. How they were able to do that is examined in this dissertation. The concept of the medicine wheel is used to metaphorically indicate the non-linearity of their journey and the inter-related and relatedness of how they were able to bridge both cultures. Understanding from the Aboriginal perspective, first-hand how they were able to succeed, to have voice and a subjective place in Western education is valuable information for those currently on, or embarking on that journey. As well, it will serve to inform post-secondary institutions and instructors of those institutions what is necessary for Aboriginal success in post-secondary education.

    The early-on estimation of required resources and a schedule for the development and maintenance of software is usually the least precise aspect of the software life cycle. However, it is desirable to make some sort of an orderly and rational attempt at estimation in order to plan and organize an implementation effort. The Software Cost Estimation Model program, SOFTCOST, was developed to provide a consistent automated resource and schedule model which is more formalized than the often used guesswork model based on experience, intuition, and luck. SOFTCOST was developed after the evaluation of a number of existing cost estimation programs indicated that there was a need for a cost estimation program with a wide range of application and adaptability to diverse kinds of software. SOFTCOST combines several software cost models found in the open literature into one comprehensive set of algorithms that compensate for nearly fifty implementation factors relative to size of the task, inherited baseline, organizational and system environment, and difficulty of the task. SOFTCOST produces mean and variance estimates of software size, implementation productivity, recommended staff level, probable duration, amount of computer resources required, and amount and cost of software documentation. Since the confidence level for a project using mean estimates is small, the user is given the opportunity to enter risk-biased values for effort, duration, and staffing, to achieve higher confidence levels. SOFTCOST then produces a PERT/CPM file with subtask efforts, durations, and precedences defined so as to produce the Work Breakdown Structure (WBS) and schedule having the asked-for overall effort and duration. The SOFTCOST program operates in an interactive environment prompting the user for all of the required input. The program builds the supporting PERT data base in a file for later report generation or revision. The PERT schedule and the WBS schedule may be printed and stored in a file for later use. The SOFTCOST program is written in Microsoft BASIC for interactive execution and has been implemented on an IBM PC-XT/AT operating MS-DOS 2.1 or higher with 256K bytes of memory. SOFTCOST was originally developed for the Zylog Z80 system running under CP/M in 1981. It was converted to run on the IBM PC XT/AT in 1986. SOFTCOST is a copyrighted work with all copyright vested in NASA.

  20. Space Weather Priorities for Kinetic-Global Modeling (Invited)

    NASA Astrophysics Data System (ADS)

    Onsager, T. G.

    2010-12-01

    Space weather is undergoing a major transformation whereby the demand for decision-capable information is beginning to far exceed our ability to produce the needed information. The limitations in our space weather capabilities are due to a number of factors, including a sparsity of data, limitations in our ability to assimilate data into our models, and the difficulties in modeling the diversity of scales and processes that control the solar-terrestrial environment. The increasing demand for space weather information creates the imperative to focus our research not only on improving our understanding of basic physical processes, but also on achieving specific outcomes that yield near-term progress in areas of high demand. Whereas, for example, full-physics, kinetic-global codes of particle acceleration and magnetic reconnection are important long-term goals, efforts to parameterize the sub-grid-scale physics or to implement intermediate solutions could lead to important near-term improvements in mitigating space weather impacts, as well as improve our understanding of the physical processes. This presentation will summarize the major areas where space weather information is needed, and discuss areas where advances in kinetic-global model development could have the most immediate impact on space weather services.

    2015-01-01

    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 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.

    Since 1990, the United Nations in cooperation with the European Space Agency is holding annually a workshop on basic space science for the benefit of the worldwide development of astronomy. These workshops have been held in countries of Asia and the Pacific (India, Sri Lanka), Latin America and the Caribbean (Costa Rica, Colombia, Honduras), Africa (Nigeria), Western Asia (Egypt, Jordan), and Europe (Germany, France). Additional to the scientific benefits of the workshops and the strengthening of international cooperation, the workshops lead to the establishment of astronomical telescope facilities in Colombia, Egypt, Honduras, Jordan, Morocco, Paraguay, Peru, Philippines, Sri Lanka, and Uruguay. The annual UN/ESA Workshops continue to pursue an agenda to network these astronomical telescope facilities through similar research and education programmes. Teaching material and hands-on astrophysics material has been developed for the operation of such astronomical telescope facilities in an university environment.

    During each school semester, students face an onslaught of material to be learned. Students work hard to achieve initial mastery of the material, but when they move on, the newly learned facts, concepts, and skills degrade in memory. Although both students and educators appreciate that review can help stabilize learning, time constraints result in a trade-off between acquiring new knowledge and preserving old knowledge. To use time efficiently, when should review take place? Experimental studies have shown benefits to long-term retention with spaced study, but little practical advice is available to students and educators about the optimal spacing of study. The dearth of advice is due to the challenge of conducting experimental studies of learning in educational settings, especially where material is introduced in blocks over the time frame of a semester. In this study, we turn to two established models of memory-ACT-R and MCM-to conduct simulation studies exploring the impact of study schedule on long-term retention. Based on the premise of a fixed time each week to review, converging evidence from the two models suggests that an optimal review schedule obtains significant benefits over haphazard (suboptimal) review schedules. Furthermore, we identify two scheduling heuristics that obtain near optimal review performance: (a) review the material from ?-weeks back, and (b) review material whose predicted memory strength is closest to a particular threshold. The former has implications for classroom instruction and the latter for the design of digital tutors. PMID:24482341

    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.

  7. Space Station Freedom solar dynamic modules structural modelling and analysis

    Lawrence, C.; Morris, R.

    1991-12-01

    In support of the Space Station Freedom (SSF) Solar Dynamic Power Module effort, structural design studies were performed to investigate issues related to the design of the power module, its pointing capabilities, and the integration of the module into the SSF infrastructure. Of particular concern from a structural viewpoint are the dynamics of the power module, the impact of the power module on the Space Station dynamics and controls, and the required control effort for obtaining the specified Solar Dynamic Power Module pointing accuracy. Structural analyses were performed to determine the structural dynamics attributes of both the existing and the proposed structural dynamics module designs. The objectives of these analyses were to generate validated Solar Dynamic Power Module NASTRAN finite element models, combine Space Station and power module models into integrated system models, perform finite element modal analyses to assess the effect of the relocations of the power module center of mass, and provide modal data to controls designers for control systems design.

    We report the derivation and implementation of orbital optimization algorithms for the active space decomposition (ASD) model, which are extensions of complete active space self-consistent field (CASSCF) and its occupation-restricted variants in the conventional multiconfiguration electronic-structure theory. Orbital rotations between active subspaces are included in the optimization, which allows us to unambiguously partition the active space into subspaces, enabling application of ASD to electron and exciton dynamics in covalently linked chromophores. One- and two-particle reduced density matrices, which are required for evaluation of orbital gradient and approximate Hessian elements, are computed from the intermediate tensors in the ASD energy evaluation. Numerical results on 4-(2-naphthylmethyl)-benzaldehyde and [3$_6$]cyclophane and model Hamiltonian analyses of triplet energy transfer processes in the Closs systems are presented. Furthermore model Hamiltonians for hole and electron transfer processes in...

    This work describes the innovative activities performed in the field of space education at the Technical University of Madrid (UPM), in collaboration with the center engaged by the European Space Agency (ESA) in Spain to support the operations for scientific experiments on board the International Space Station (E-USOC). These activities have been integrated along the last academic year of the Aerospatiale Engineering degree. A laboratory has been created, where the students have to validate and integrate the subsystems of a microsatellite by using demonstrator satellites. With the acquired skills, the students participate in a training process centered on Project Based Learning, where the students work in groups to perform the conceptual design of a space mission, being each student responsible for the design of a subsystem of the satellite and another one responsible of the mission design. In parallel, the students perform a training using a ground station, installed at the E-USOC building, which allow them to learn how to communicate with satellites, how to download telemetry and how to process the data. This also allows students to learn how the E-USOC works. Two surveys have been conducted to evaluate the impact of these techniques in the student engineering skills and to know the degree of satisfaction of students with respect to the use of these learning methodologies.

    Just like decent classical difference-difference systems define symplectic maps on suitable phase spaces, their counterparts with properly ordered noncommutative entries come as Heisenberg equations of motion for corresponding quantum discrete-discrete models. We observe how this idea applies to a difference-difference counterpart of the Liouville equation. We produce explicit forms of of its evolution operator for the two natural space-time coordinate systems. We discover that discrete-discrete models inherit crucial features of their continuous-time parents like locality and integrability while the new-found algebraic transparency promises a useful progress in some branches of Quantum Inverse Scattering Method.

An analytical understanding of foam mechanics is required to design against structural failure. The Space Shuttle External Tank is covered primarily with closed cell foam to: Prevent ice, Protect structure from ascent aerodynamic and engine plume heating, and Delay break-up during re-entry. It is important that the foam does not shed unacceptable debris during ascent environment. Therefore a modeling of the foam insulation was undertaken.

    This paper aims to enlarge the usual scope of disease mapping by means of dynamic mixtures (DMDM) in case a time component is involved in the data. A special mixture model is suggested which looks for space-time components (clusters) simultaneously. The idea is illustrated using data on female lung cancer from the East German cancer registry for 1960-1989. The conventional mixed Poisson regression model is used as a third model for comparison. The models are discussed in terms of their benefits, difficulties and ease in interpretation, as well as their statistical meaning. Some ideas on evaluation of these models are also included.

    The distorting effect of peculiar velocities on the power speturm and correlation function of IRAS and optical galaxies is studied. The observed redshift space power spectra and correlation functions of IRAS and optical the galaxies over the entire range of scales are directly compared with the corresponding redshift space distributions using large-scale computer simulations of cold dark matter (CDM) models in order to study the distortion effect of peculiar velocities on the power spectrum and correlation function of the galaxies. It is found that the observed power spectrum of IRAS and optical galaxies is consistent with the spectrum of an Omega = 1 CDM model. The problems that such a model currently faces may be related more to the high value of Omega in the model than to the shape of the spectrum. A low-density CDM model is also investigated and found to be consistent with the data.

  19. A virtual manipulator model for space robotic systems

    Dubowsky, S.; Vafa, Z.

    1987-01-01

    Future robotic manipulators carried by a spacecraft will be required to perform complex tasks in space, like repairing satellites. Such applications of robotic manipulators will encounter a number of kinematic, dynamic and control problems due to the dynamic coupling between the manipulators and the spacecraft. A new analytical modeling method for studying the kinematics and dynamics of manipulators in space is presented. The problem is treated by introducing the concept of a Virtual Manipulator (VM). The kinematic and dynamic motions of the manipulator, vehicle and payload, can be described relatively easily in terms of the Virtual Manipulator movements, which have a fixed base in inertial space at a point called a Virtual Ground. It is anticipated that the approach described here will aid in the design and development of future space manipulator systems.

    The extravehicular activity (EVA) required to assemble the International Space Station (ISS) will take approximately 1500 hours with 400 hours of EVA per year in operations and maintenance. With the Space Station at an inclination of 51.6 deg the radiation environment is highly variable with solar activity being of great concern. Thus, it is important to study the dose gradients about the body during an EVA to help determine the cancer risk associated with the different environments the ISS will encounter. In this paper we are concerned only with the trapped radiation (electrons and protons). Two different scenarios are looked at: the first is the quiet geomagnetic periods in low Earth orbit (LEO) and the second is during a large solar particle event in the deep space environment. This study includes a description of how the space suit's computer aided design (CAD) model was developed along with a description of the human model. Also included is a brief description of the transport codes used to determine the total integrated dose at several locations within the body. Finally, the results of the transport codes when applied to the space suit and human model and a brief description of the results are presented.

    NASA Astrophysics Data System (ADS)

    Se, Stephen; Jasiobedzki, Piotr; Wildes, Richard

    2007-04-01

    Servicing satellites in space requires accurate and reliable 3D information. Such information can be used to create virtual models of space structures for inspection (geometry, surface flaws, and deployment of appendages), estimation of relative position and orientation of a target spacecraft during autonomous docking or satellite capture, replacement of serviceable modules, detection of unexpected objects and collisions. Existing space vision systems rely on assumptions to achieve the necessary performance and reliability. Future missions will require vision systems that can operate without visual targets and under less restricted operational conditions towards full autonomy. Our vision system uses stereo cameras with a pattern projector and software to obtain reliable and accurate 3D information. It can process images from cameras mounted on a robotic arm end-effector on a space structure or a spacecraft. Image sequences can be acquired during relative camera motion, during fly-around of a spacecraft or motion of the arm. The system recovers the relative camera motion from the image sequence automatically without using spacecraft or arm telemetry. The 3D data computed can then be integrated to generate a calibrated photo-realistic 3D model of the space structure. Feature-based and shape-based approaches for camera motion estimation have been developed and compared. Imaging effects on specular surfaces are introduced by space materials and illumination. With a pattern projector and redundant stereo cameras, the robustness and accuracy of stereo matching are improved as inconsistent 3D points are discarded. Experiments in our space vision facility show promising results and photo-realistic 3D models of scaled satellite replicas are created.

    1995-12-31

    A Fortran computer model, SHADOW5, was developed to predict shadows on the solar arrays of the International Space Station Alpha (ISSA) for general flight modes. This shadow model was incorporated into the EPSOP-F (Electrical Power System On-Orbit Performance) program to conduct ISSA power analyses for various operating conditions. This paper describes the mathematical methods of the model and shows the typical results predicted with the model. Vector analyses with coordinate transformations were used to trace the shadows between the potential shadowing and shadowed components of the station during the sun portion of the orbit. Including the space shuttle orbiter, 40 components were modeled. The basic shapes of the components were assumed to be either planar or cylindrical. The elemental areas obtained from the Cartesian grid lines allocated on the component surfaces were projected in the sun vector direction to reconstruct shadows on the shadowed planar surface. Comparison of predicted results with other models showed good agreement. Ease of preparing input data and relatively short CPU time make this model suitable for shadow analyses required for the many design and flight configurations of the space station.

  6. Joint space-time geostatistical model for air quality surveillance

    Russo, A.; Soares, A.; Pereira, M. J.

    2009-04-01

    Air pollution and peoples' generalized concern about air quality are, nowadays, considered to be a global problem. Although the introduction of rigid air pollution regulations has reduced pollution from industry and power stations, the growing number of cars on the road poses a new pollution problem. Considering the characteristics of the atmospheric circulation and also the residence times of certain pollutants in the atmosphere, a generalized and growing interest on air quality issues led to research intensification and publication of several articles with quite different levels of scientific depth. As most natural phenomena, air quality can be seen as a space-time process, where space-time relationships have usually quite different characteristics and levels of uncertainty. As a result, the simultaneous integration of space and time is not an easy task to perform. This problem is overcome by a variety of methodologies. The use of stochastic models and neural networks to characterize space-time dispersion of air quality is becoming a common practice. The main objective of this work is to produce an air quality model which allows forecasting critical concentration episodes of a certain pollutant by means of a hybrid approach, based on the combined use of neural network models and stochastic simulations. A stochastic simulation of the spatial component with a space-time trend model is proposed to characterize critical situations, taking into account data from the past and a space-time trend from the recent past. To identify near future critical episodes, predicted values from neural networks are used at each monitoring station. In this paper, we describe the design of a hybrid forecasting tool for ambient NO2 concentrations in Lisbon, Portugal.

This paper reviews the methodology used to develop space telescope cost models; summarizes recently published single variable models; and presents preliminary results for two and three variable cost models. Some of the findings are that increasing mass reduces cost; it costs less per square meter of collecting aperture to build a large telescope than a small telescope; and technology development as a function of time reduces cost at the rate of 50% per 17 years.

    The Aerospace Corporation (Aerospace) and Lockheed Martin Space Systems (LMSS) participated with Jet Propulsion Laboratory (JPL) in the implementation of a magnetic cleanliness program of the NASA/JPL JUNO mission. The magnetic cleanliness program was applied from early flight system development up through system level environmental testing. The JUNO magnetic cleanliness program required setting-up a specialized magnetic test facility at Lockheed Martin Space Systems for testing the flight system and a testing program with facility for testing system parts and subsystems at JPL. The magnetic modeling, simulation and analysis capability was set up and performed by Aerospace to provide qualitative and quantitative magnetic assessments of the magnetic parts, components, and subsystems prior to or in lieu of magnetic tests. Because of the sensitive nature of the fields and particles scientific measurements being conducted by the JUNO space mission to Jupiter, the imposition of stringent magnetic control specifications required a magnetic control program to ensure that the spacecraft's science magnetometers and plasma wave search coil were not magnetically contaminated by flight system magnetic interferences. With Aerospace's magnetic modeling, simulation and analysis and JPL's system modeling and testing approach, and LMSS's test support, the project achieved a cost effective approach to achieving a magnetically clean spacecraft. This paper presents lessons learned from the JUNO magnetic testing approach and Aerospace's modeling, simulation and analysis activities used to solve problems such as remnant magnetization, performance of hard and soft magnetic materials within the targeted space system in applied external magnetic fields.

    System engineering practices for complex systems and networks now require that requirement, architecture, and concept of operations product development teams, simultaneously harmonize their activities to provide timely, useful and cost-effective products. When dealing with complex systems of systems, traditional systems engineering methodology quickly falls short of achieving project objectives. This approach is encumbered by the use of a number of disparate hardware and software tools, spreadsheets and documents to grasp the concept of the network design and operation. In case of NASA's space communication networks, since the networks are geographically distributed, and so are its subject matter experts, the team is challenged to create a common language and tools to produce its products. Using Model Based Systems Engineering methods and tools allows for a unified representation of the system in a model that enables a highly related level of detail. To date, Program System Engineering (PSE) team has been able to model each network from their top-level operational activities and system functions down to the atomic level through relational modeling decomposition. These models allow for a better understanding of the relationships between NASA's stakeholders, internal organizations, and impacts to all related entities due to integration and sustainment of existing systems. Understanding the existing systems is essential to accurate and detailed study of integration options being considered. In this paper, we identify the challenges the PSE team faced in its quest to unify complex legacy space communications networks and their operational processes. We describe the initial approaches undertaken and the evolution toward model based system engineering applied to produce Space Communication and Navigation (SCaN) PSE products. We will demonstrate the practice of Model Based System Engineering applied to integrating space communication networks and the summary of its results and impact. We will highlight the insights gained by applying the Model Based System Engineering and provide recommendations for its applications and improvements.
