Space ecoliteracy- five informal education models for community empowerment  

NASA Astrophysics Data System (ADS)

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

Dedicated Space Science Education Centres Provide the Model for Effective Outreach  

NASA Astrophysics Data System (ADS)

Planetaria and science centres are traditionally successful players in engaging all levels and ages of society. They have long played a supportive role to and within education. Their value in teacher circles has always been recognised as an effective resource. Given the decline in career choices in traditional Science Technology Engineering and Mathematics (STEM) and astronomy and planetary sciences, they are now more important than ever. Since their inception the role and function of Planetaria has been required to evolve to meet the changing demands of society. They are now faced with the challenge of meeting new requirements and the need for new and different resources, techniques, support and funding models to meet and effectively deliver to new target groups. To face these challenges these pivotal centres require new methodology in their development of programs to be effective in their support to education. New directions specifically tailored for teacher professional development and for student studies. The changing requirements have resulted in a new kind of science centre one dedicated and specially designed using space science and dedicated to formal education across stem activities. The space scientist forms an integral and key role in this type of centre by providing the science, the passion of discovery and the relevance of the science to the community. These programs need to be carefully aligned to flexible course requirements and objectives to ensure relevancy to the education and outreach sector. They need access to and the support and input from the scientist and research institutions. They need real and appropriate material and resources. Scientists need effective channels through which to inform and share their work. Here is the potential for enormously effective symbiosis. This paper describes how new multi million dollar state-of-the-art space science centres are working with cutting edge science, research institutes, universities, government education departments, all education stakeholders and deliverers in formal, informal and non-specialist education support. The dedicated space education centres provide realistic prototypes for the restructuring of existing planetaria and science centres to meet needs of education in 21st Century.

Space physics educational outreach  

NASA Technical Reports Server (NTRS)

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.

Using sunshine for elementary space science education: A model for IHY scientist teacher partnerships  

NASA Astrophysics Data System (ADS)

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

Using the Earth as an Effective Model for Integrating Space Science Into Education Outreach Programs  

NASA Astrophysics Data System (ADS)

Our methods of teaching Earth and space science as two disciplines do not represent the spirit of earlier scientists such as Aristotle, da Vinci, and Galileo. We need to re-evaluate these methods and take advantage of the excitement created in the general public over the recent space science exploration programs. The information that we are obtaining from both the Mars missions and Cassini-Huygens focuses on interpreting geomorphology, mineral compositions and gas identification based on Earth as a baseline for data evaluation. This type of evaluation is an extension of Hutton's 18th century principle of Uniformitarianism, the present is the key to the past, or Earth is the key for understanding extraterrestrial bodies. Geomorphological examples are volcanic activity, meteoritic impacts, and evidence of water altering surface features. The Hawaiian, or shield, type volcanoes are analogues for Olympus Mons and the other volcanoes on Mars. Other examples include comparing sand dunes on Earth with possible Martian dunes, known stream patterns on Earth with potential stream patterns on Mars, and even comparing meteoritic impact features on Mars, the Earth, Moon and Mercury. All of these comparisons have been developed into inquiry-based activities and are available through NASA publications. Each of these activities is easily adapted to emphasize either Earth science or space science or both. Beyond geomorphology, solar storms are an excellent topic for integrating Earth and space science. Solar storms are traditionally part of space science studies, but most students do not understand their effect on Earth or the intense effects they could have on humans, whether traveling through space or exploring the surfaces of the Moon or Mars. Effects are not only limited to space travel and other planetary surfaces but also include Earth's magnetosphere, which in turn, affect radio transmission and potentially climate. Like geomorphology courses, there are extensive NASA programs available via either the Internet or CD (e.g., those distributed by P. Reiff, Rice University) that provide inquiry-based activities for students. There is great potential to share the connections of Earth and space science by using NASA developed education materials. The materials can be adapted for the classroom, after school programs, family outreach events, and summer science enrichment programs.

Space Science and Interdisciplinary Education  

NASA Astrophysics Data System (ADS)

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

Operational Space Weather in USAF Education  

NASA Astrophysics Data System (ADS)

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.

Four educational programs in space life sciences  

NASA Astrophysics Data System (ADS)

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

The program combines innovative and flexible new approaches with time-tested methods to give participants the skills required for future missions and new business, while allowing participants to meet their work commitments at the same time as they study for their master's degree. The SpaceTech program is conducted in separate sessions, generally each of 2-week duration, separated by periods of some 6-8 weeks, during which time participants may return to their normal jobs. 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.

Educational space probe model system of lander (Hunveyor), rover (Husar) and test-terrain for planetary science education and analog studies in universities and colleges of Hungary.  

NASA Astrophysics Data System (ADS)

In 1997 we began a complex modelling program in planetary geology unifying field work robotics, electronics and complex environmental analysis by constructing an experimental space probe model system. It consists of an experimental lander HUNVEYOR (Hungarian UNiversity surVEYOR), a rover named HUSAR (Hungarian University Surface Analyser Rover) and a test terrain. For Hunveyor the idea and example was the historical Surveyor program of NASA in the 1960-ies, for the Husar the idea and example was the Pathfinder's rover Sojouner rover. The main goals of this program are: 1) to teach the complex work of planetary science according to the main operations of the procedure of the large scientific and technology system, 2) to build the lander structure and basic electronics from cheap everyday PC compatible elements, 3) to construct basic experiments and their instruments, 4) to use the system as a space activity simulator, 5) to form the electronics of this simulator system which contains lander (with on board computer) for works on a test planetary surface, and a "terrestrial control" computer, "talking" with each other, 6) to harmonize the assemblage of the electronic system and instruments in various levels of autonomy from the power and communication circuits, 7) to use the complex system in education for in situ understanding of the complex planetary environmental problems, 8) to build various planetary environments on the test terrain in order to apply the instrument assemblages in various testing conditions, 9) to use the model system with special internet connections capable of communicating in the web in field trip conditions for users, and 10) to use the model system in real planetary analog field trip simulations, first in Hungary and later in some planetary analog site in the world. We report some of these visits in Hungary and Utah, USA. REFERENCES: [1] Bérczi Sz., Cech V., Hegyi S., Borbola T., Diósy T., Köll? Z., o 1 Tóth Sz.

Radiation Storm vs. The Magnetic Shield: Superheroes of Magnetism & Space Weather Education - A Model for Teacher Professional Development Workshops  

NASA Astrophysics Data System (ADS)

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

Challenges of Space Education in the Philippines  

NASA Astrophysics Data System (ADS)

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

Space technology education programs in Narvik  

NASA Astrophysics Data System (ADS)

In 1996 the space technology education at Bachelor level was established at Narvik University College (HIN) and in the year 1999 the Master programme opened. Both these programmes are the first and only in Norway of their kind. The programmes, while having a strong space flavour are designed to be broad and generally qualify students for a wide range of opportunities for professional careers. Basically these are educations within electronics with emphasis on communication, basic space technology, space physics and spacecraft dynamics. HIN will conduct an evaluation workshop in June 2005 where representatives from industry in space technology will give feedback on the education. Laboratory resources have been complemented with space related equipment so that theory can be related to practical work in a qualified way wherever relevant. HIN students have been engaged in a number of interesting space technology diploma projects that have been given by national companies and institutions. Currently different groups are engaged in international space technology student projects. HIN has filled a research fellow position associated to research on attitude and orbit control of spacecraft formations. Recently HIN also engaged a visiting professor in space technology.

Space industrialization - Education. [via communication satellites  

NASA Technical Reports Server (NTRS)

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.

Space Education and Public awareness in Nepal  

NASA Astrophysics Data System (ADS)

Nepalese students are curious with space missions of China and India. The possibility of space mission is not imminent to Nepal for the next few decades. To develop space activities and to industrialize astronomy, base of space education in the high schools must be very effective. This paper highlights the present scenario of space education and discusses the syllabus of astronomy in the different education level of Nepal. Astronomy is included in the syllabus of science book of middle school and high school which contains very few contents of solar system, constellations, galaxy, black holes and formation of stars. There is no any degree for higher studies in astronomy as a separate department in any university of Nepal. This paper also highlights the space activities and national level programs conducting in Nepal. With the rise of many astronomical clubs and societies in the different regions of Nepal, astronomy outreach has been more effective in the recent time. Methods of astronomy outreach and public awareness that are being used in Nepal will be discussed in brief and how these programs have affected to create interest of students and public in astronomy will be mentioned in brief.

Space shuttle simulation model  

NASA Technical Reports Server (NTRS)

The effects of atmospheric turbulence in both horizontal and near horizontal flight, during the return of the space shuttle, are important for determining design, control, and 'pilot-in-the-loop' effects. A nonrecursive model (based on von Karman spectra) for atmospheric turbulence along the flight path of the shuttle orbiter was developed which provides for simulation of instantaneous vertical and horizontal gusts at the vehicle center-of-gravity, and also for simulation of instantaneous gust gradients. Based on this model, the time series for both gusts and gust gradients were generated and stored on a series of magnetic tapes which are entitled shuttle simulation turbulence tapes (SSTT). The time series are designed to represent atmospheric turbulence from ground level to an altitude of 10,000 meters. The turbulence generation procedure is described as well as the results of validating the simulated turbulence. Conclusions and recommendations are presented and references cited. The tabulated one dimensional von Karman spectra and the results of spectral and statistical analyses of the SSTT are contained in the appendix.

Educational Outreach: The Space Science Road Show  

NASA Astrophysics Data System (ADS)

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.

Education of a model student  

PubMed Central

A dilemma faced by teachers, and increasingly by designers of educational software, is the trade-off between teaching new material and reviewing what has already been taught. Complicating matters, review is useful only if it is neither too soon nor too late. Moreover, different students need to review at different rates. We present a mathematical model that captures these issues in idealized form. The student’s needs are modeled as constraints on the schedule according to which educational material and review are spaced over time. Our results include algorithms to construct schedules that adhere to various spacing constraints, and bounds on the rate at which new material can be introduced under these schedules. PMID:22308334

The FRT quantum Euclidean spaces $O_q^N$ are formulated in terms of Cartesian generators. The quantum analogs of N-dimensional Cayley-Klein spaces are obtained by contractions and analytical continuations. Noncommutative constant curvature spaces are introduced as a spheres in the quantum Cayley-Klein spaces. For N=5 part of them are interpreted as the noncommutative analogs of (1+3) space-time models. As a result the quantum (anti) de Sitter, Newton, Galilei kinematics with the fundamental length and the fundamental time are suggested.

Space science education and training in Brazil  

NASA Astrophysics Data System (ADS)

With the beginning of space research in Brazil in the early 60's a national commission for space activities was created. This commission took important steps, in parallel, to create a program of education and training activities that was forseen as of critical importance for the maintenance of a desirable to ambitious degree of space activity in the country. Early efforts were, as a first step, in favour of training of Brazilian students in foreign centers of excellence (mostly in the US and Europe), as a means for achieving the potential human resource necessary for eventual development of a national program. Today a large percentage of the needs in the area is met by programs developed inside the country at different institutions, the most notable being the ``Instituto Nacional de Pesquisas Espaciais'' - INPE (National Institute for Space Research) at Sa~o José dos Campos, where post graduate courses and training programs are well established. Under-graduate courses in selected areas are provided at some Universities, notably at the University of Sa~o Paulo. A brief description of the existing programs and an evaluation of the results being achieved are presented in this paper.

Modeling Chandra Space Environment  

NASA Technical Reports Server (NTRS)

This paper describes the development of an environmental risk-mitigation tool for the Chandra X-ray Observatory's Advanced CCD Imaging Spectrometer (ACIS). Because exposure to 100-200 keV protons appears to have degraded the front-illuminated CCD's charge transfer inefficiency (CTI), an accurate tool for predicting encounters with magnetospheric regions rich in these particles is required. We implement standard models to predict bow-shock, magnetopause, and plasma-sheet boundaries. Using these models and solar-wind databases compiled from IMP-8 and ACE measurements, we then calculate the probability that Chandra is located in one of these regions, along with predicted particle flux, to arrive at appropriate safing times for the ACIS detector. Finally, we validate this tool by comparing the model's boundary-crossing and proton flux predictions with measurements from Chandra's on-board particle detector and with data from other spacecraft operating in the Earth's magnetosphere.

Uptake of Space Technologies - An Educational Programme  

NASA Astrophysics Data System (ADS)

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

A river model of space  

E-print Network

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.

Understanding Models in Earth and Space Science  

NSDL National Science Digital Library

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.

Ejs Phase Space Plotter Model  

NSDL National Science Digital Library

The Ejs Phase Space Plotter model displays the dynamics of an ensemble of pendula or simple harmonic oscillators in phase space (velocity versus position). Friction is initially set to zero but can be changed via a textbox as can the number of elements in the ensemble. For the pendulum ensemble, the Cylinder checkbox keeps the angular position between âpi and pi for large initial angular velocities. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting âOpen Ejs Modelâ from the pop-up menu item. Ejs Phase Space Plotter model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_ehu_analytical_mechanics_phase_space.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for Newtonian mechanics are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.

Space education and outreach symposium (E1.). Structures for space education (2.)  

NASA Astrophysics Data System (ADS)

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.

Outreach Education Modules on Space Sciences in Taiwan  

NASA Astrophysics Data System (ADS)

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 Space Laser Business Model  

NASA Technical Reports Server (NTRS)

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.

International Space Station: National Laboratory Education Concept Development Report  

NASA Technical Reports Server (NTRS)

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

Driven Pendulum with Phase Space Model  

NSDL National Science Digital Library

The Driven Pendulum with Phase Space Model computes and displays the dynamics of a damped and driven pendulum, its phase space, and its Poincare section.  The model displays pendulum motion in the main window and the phase space in a second window. Because a phase space trajectory can be very complicated, the motion is easier to analyze by plotting a point in phase space after every cycle (period T) of the external force. Such a phase space plot is called a Poincare map. The Driven Pendulum with Phase Space Model was developed using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the model's jar file will run the simulation if Java is installed.

Advanced Space Shuttle simulation model  

NASA Technical Reports Server (NTRS)

The effects of atmospheric turbulence in horizontal and near-horizontal flight during the return of the Space Shuttle are important for determining design, control, and pilot-in-the-loop effects. A nonrecursive model (based on vonKarman spectra) for atmospheric turbulence along the flight path of the Shuttle Orbiter has been developed which provides for simulation of instantaneous vertical and horizontal gusts at the vehicle center-of-gravity and also for simulation of instantaneous gust gradients. Based on this model the time series for gusts and gust gradients have been generated and stored on a series of magnetic tapes which are 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, and conclusions and recommendations are presented. Appendices provide tabulated one-dimensional vonKarman spectra, a discussion of the minimum frequency simulated, and the results of spectral and statistical analyses of the SSTT.

Space Sciences Education and Outreach Project of Moscow State University  

NASA Astrophysics Data System (ADS)

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.

Transitioning Models and Model Output to Space Weather Operations: Challenges and Opportunities  

NASA Technical Reports Server (NTRS)

The transition of space weather models or of information derived from space weather models to space weather forecasting is the last step of the chain from model development to model deployment in forecasting operations. As such, it is an extremely important element of the quest to increase our national capability to forecast and mitigate space weather hazards. It involves establishing customer requirements, and analyses of available models, which are, in principle, capable of delivering the required product. Models will have to be verified and validated prior to a selection of the best performing model. Further considerations include operational hardware, and the availability of data streams to drive the model. The final steps include the education of forecasters, and the implementation on gateway hardware prior to operational use. This presentation will provide a discussion of opportunities for rapid progress from the viewpoint of the Community Coordinated Modeling Center.

Space Plasma Science as a Motivator for Education & Outreach  

NASA Astrophysics Data System (ADS)

Education and public outreach (EPO) continue to play an important role in how science is funded by the federal government. The plasma science community has a responsibility to share their exciting science with the American public. Bruce Alberts, president of the National Academy of Sciences, and Neal Lane, former head of NSF, are on record as strong advocates of scientists becoming more actively and effectively engaged in K-12 science education reform. In addition, research directorates of funding agencies like NASA and NSF are increasingly encouraging (and in some cases requiring) the integration of science and education and greater scientist involvement in EPO. How does plasma science and scientists fit into this broader political and social landscape? How well does the public understand our science and technology? Are there ways to effectively engage the public that provide good visibility for plasma science? These questions and more will be addressed in this talk. The Space Science Institute (SSI), a nonprofit organization in Colorado, provides national leadership in developing innovative ways to translate the activities and resources of space and earth science research into exciting and effective K-12 and museum education programs. SSI’s mission is to link its space science research enterprise with its education programs. SSI has active programs in curriculum and exhibit development and professional development for both scientists about education and for educators about science. I will share with you one exhibit project and one curriculum project whose goals are to raise public understanding of space plasmas and by extension all of plasma science.

The use of urban space as an educational space for work on astronomy  

NASA Astrophysics Data System (ADS)

For several years we have been using urban space, with its squares, monuments, astronomical observatories and ancient ruins, as “educational space” in order to take school into large open-air spaces renowned for their history and cultural importance outside the premises of the school itself. So that this practice, whose validity and effectiveness for teaching will be demonstrated in what follows, may be more frequently experienced with students, we hold that it is necessary to put it forward to trainee and practising teachers in order that they are able to employ it with their students.

Space science education-an interdisciplinary and international programme  

NASA Astrophysics Data System (ADS)

The ISU's Master of Space Studies (MSS) programme is a new, unique and interdisciplinary postgraduate course of eleven months duration. It is designed for those who will lead and work in the international space programmes of the next century. It considers not only many aspects of the space sciences and their applications, but also most engineering, business, management, policy and law issues relevant to the activities of both space agencies and space industries. In the first term, fundamental issues are covered, and MSS participants from many countries around the world select some topics of their choice; within the sciences, attention is focused on basic physics, the space environment and life sciences. In the second and third terms, advanced subjects ranging from astronomy to planetary sciences, microgravity sciences, telecommunications and remote sensing of the Earth's surface and atmosphere are available. For two months in the second term, each participant carries out a project at an affiliate campus or an associated institution, and prepares a written report on this. Throughout the year, all participants play an active part in a team design project on a chosen theme; a substantial written report is prepared, and the results are also presented orally. Thus the aim of the MSS programme is to educate space generalists, yet generalists who are knowledgeable in all the relevant disciplines, including science.

Transforming Community Access to Space Science Models  

NASA Technical Reports Server (NTRS)

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

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

NASA Astrophysics Data System (ADS)

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.

Advanced Space Shuttle simulation model  

NASA Technical Reports Server (NTRS)

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.

Homogeneous spaces and Faddeev-Skyrme models  

NASA Astrophysics Data System (ADS)

We study geometric variational problems for a class of models in quantum field theory known as Faddeev-Skyrme models. Mathematically one considers minimizing an energy functional on homotopy classes of maps from closed 3-manifolds into homogeneous spaces of compact Lie groups. The energy minimizers known as Hopfions describe stable configurations of subatomic particles such as protons and their strong interactions. The Hopfions exhibit distinct localized knot-like structure and received a lot of attention lately in both mathematical and physical literature. High non-linearity of the energy functional presents both analytical and algebraic difficulties for studying it. In particular we introduce novel Sobolev spaces suitable for our variational problem and develop the notion of homotopy type for maps in such spaces that generalizes homotopy for smooth and continuous maps. As the spaces in question are neither linear nor even convex we take advantage of the algebraic structure on homogeneous spaces to represent maps by gauge potentials that form a linear space and reformulate the problem in terms of these potentials. However this representation of maps introduces some gauge ambiguity into the picture and we work out 'gauge calculus' for the principal bundles involved to apply the gauge-fixing techniques that eliminate the ambiguity. These bundles arise as pullbacks of the structure bundles H ? G ? G/H of homogeneous spaces and we study their topology and geometry that are of independent interest. Our main results include proving existence of Hopfions as finite energy Sobolev maps in each (generalized) homotopy class when the target space is a symmetric space. For more general spaces we obtain a weaker result on existence of minimizers only in each 2-homotopy class.

Innovative Space Sciences Education Programs for Young People  

NASA Astrophysics Data System (ADS)

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.

Rejoinder: sifting through model space  

USGS Publications Warehouse

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.

Understanding Models in Earth and Space Science (e-book)  

NSDL National Science Digital Library

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.

Louisiana, A Leader in Earth and Space Science Education  

NASA Astrophysics Data System (ADS)

Earth and Space Science is too often viewed as a peripheral science compared to chemistry, biology, and physics. It is typically found integrated with geography, ecology, and general science in various stages of the curriculum, and is rarely considered holistically or as a discrete discipline. The status of earth and space science is also commonly reflected in the inadequate preparation of teachers and in the lack of government recognition of the value of earth science education. Louisiana is a state that does not follow the typical trend. It is a leader in earth and space science education with its cadre of programs that impact teacher preparation, state testing programs, curriculum development and technology initiatives. The state science framework introduces earth science in middle school. Grades 5-7 have an integrated science curriculum that includes an earth science component. Grade 8 has either an earth science or an integrated science course depending upon the availability of certified teachers in the district. Earth science is also included in Louisiana's high school science curriculum. It satisfies one science credit required for graduation. The Louisiana Educational Assessment Program (LEAP 21) and the Graduation Exit Exam (GEE 21) compose Louisiana's new criterion-referenced testing program. The content standards measured by the LEAP 21/GEE 21science tests include earth and space science. The LEAP 21 is administered at grades 4 and 8, and the GEE 21 at grades 10 and 11. Students have to pass the GEE 21 to graduate from high school. Therefore, all students graduating from a Louisiana high school will have been exposed to earth science concepts multiple times throughout their K-12 schooling. Louisiana also has an array of programs that provide statewide curriculum and student resources and professional development that impact earth and space science education. The Making Connections Project provides web-site resources and lesson plans that have been aligned with the Louisiana Content Standards, which include the earth and space science benchmarks. This web-based resource is available to students, teachers, administrators, and parents. Another Louisiana program is the GIS K-12 Initiative- Where in the World? It introduces K-12 students and teachers to GIS systems. It helps students develop a spatial understanding of the earth's surface, use maps, create maps, and make connections between man and his environment. ThinkQuest Camp is another program that impacts earth and space science in Louisiana. It is a camp designed for students and teachers to build content-rich websites to share with their peers around the world. All of the above mentioned programs are structured around the state science benchmarks, which include earth and space science. Louisiana has incorporated a strong earth and space component into its science curriculum and continues to be a leader in the nation's effort towards science education reform.

Cognitive engineering models in space systems  

NASA Technical Reports Server (NTRS)

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.

The Space Weather Living History: Connecting Scientists with Students, Educators and the Public  

NASA Astrophysics Data System (ADS)

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.

Developing a STEM Education Pipeline Using Astronomy and Space Science  

NASA Astrophysics Data System (ADS)

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

Model analysis of Space Shuttle dosimetry data  

NASA Technical Reports Server (NTRS)

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

Ejs Liouvilleâs Theorem Phase Space Plotter Model  

NSDL National Science Digital Library

The Ejs Liouvilleâs Theorem Phase Space Plotter model displays the dynamics of an ensemble of pendula or simple harmonic oscillators in phase space (velocity versus position). Friction is initially set to zero but can be changed via a textbox as can the number of elements in the ensemble. The initial starting point of each element in the ensemble forms a particular shape (square, hollow square, disk, or circle). Therefore at the beginning of the simulation, each starting point is near the others and the red center point in phase space. For the pendulum ensemble, the Cylinder checkbox keeps the angular position between âpi and pi for large initial angular velocities. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting âOpen Ejs Modelâ from the pop-up menu item. Ejs Liouvilleâs Theorem Phase Space Plotter model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_ehu_analytical_mechanics_Liouville.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for Newtonian mechanics are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.

Mouse infection models for space flight immunology  

NASA Technical Reports Server (NTRS)

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.

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

Thermodynamics of space quanta models quantum gravity  

E-print Network

Canonically quantized 3+1 general relativity with the global one dimensionality (1D) conjecture defines the model, which dimensionally reduced and secondary quantized yields the 1D quantum field theory wherein generic one-point correlations create physical scales. This simple quantum gravity model, however, can be developed in a wider sense. In this paper we propose to consider ab initio thermodynamics of space quanta as the quantum gravity phenomenology. The thermodynamics is constructed in the entropic formalism.

Meeting Classroom Needs: Designing Space Physics Educational Outreach for Science Education Standards  

NASA Astrophysics Data System (ADS)

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

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

United States Changing Demographics - English/Spanish Space Education  

NASA Astrophysics Data System (ADS)

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.

The optical modeling of laser beam propagation between two points on the earth's surface is discussed with reference to a space relay experiment using relay mirrors on one or more satellites. A two-dimensional laser beam propagation code is applied, and several novel modules are developed to realistically model the environment of the experiment. These are the Kolmogorov atmosphere, a deformable mirror, a segmented aperture, and wind shear. The model allows the calculation of the beam-Strehl ratio and efficiency of the energy transfer for an arbitrary input beam distribution.

A geometric delay model for Space VLBI  

E-print Network

A relativistic delay model for space very long baseline interferometry (hereafter SVLBI) observation of sources at infinite distance is derived. In SVLBI, where one station is on a spacecraft, the orbiting station's maximum speed in an elliptical Earth orbit is much bigger than the ground VLBI (here after GVLBI), leading to a higher delay rate . The delay models inside the VLBI correlators are usually expressed as fifth-order polynomials in time that good for a limited time interval, which are evaluated by the correlator firmware and track the interferometer delays over a limited time interval. The higher SVLBI delay rate requires more accurate polynomial fitting and evalution, more frequent model updates.

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.

Adaptive Numerical Algorithms in Space Weather Modeling  

NASA Technical Reports Server (NTRS)

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.

Joint spacing criterion for equivalent continuum model  

SciTech Connect

Currently, the Yucca Mountain Site Characterization Project is investigating the feasibility of the disposal of high-level radioactive waste in the unsaturated Topopah Spring formation. The Topopah Spring formation is a heavily fractured, predominantly vertically jointed, welded tuff, and the potential disposal area is cut by the Ghost Dance fault and bounded by several other faults structures. The joints in the tuff and the faults may have an impact on the emplacement drift or borehole stability, as well as on the movement of fluids through the rock mass. The design of the repository drifts and layout, the waste emplacement scheme, and the thermomechanical performance of the rock mass will be analyzed using various numerical models. These models may be based on different assumptions regarding the representation of the fracture behavior under given applied stresses, and will range from discrete models where individual mechanically active fractures are treated distinctly, to continuum models where the joint behavior is smeared over a representative volume. There is always the question of applicability of a model with respect to a given material domain to be analyzed. For the mechanical analysis of the rock mass response around a repository drift, the applicability of an equivalent continuum model is dependent on the joint spacing in the rock mass. Considering the joint spacings that may be encountered at the potential repository site, a ratio of joint spacing to the planned drift diameter may be adopted as a criterion for evaluating the applicability of the Compliant Joint Model (CJM) in the Yucca Mountain Site Characterization Project. In this paper, this criterion is established by reviewing basic continuum concepts and numerical approximation implications used to build the CJM and by examining rock mass conditions that may be encountered at the potential Yucca Mountain repository site.

Modelling early failures in Space Station Freedom  

NASA Technical Reports Server (NTRS)

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

We 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.

A survey of space cost models  

NASA Astrophysics Data System (ADS)

How do cost models help in making economic decisions about space transportation vehicles? To what extent do cost models illuminate the cost impact of decisions due to management, technical, engineering and manufacturing, and cultural factors? What types of cost explanatory variables are used and what are their impacts? We shall first identify cost drivers across several space cost models: PRICE-H, SEER-H, TRANSCOST, and NAFCOM, and then classify them by using a management cost reduction matrix. Second, we shall review cost explanatory variables for vehicle structure, engine system, and process and technical parameters. Third, we will present a simple baseline, consisting of a launch vehicle structure and engine and discuss methodology to develop the inter-model comparison of cost drivers. Fourth, we will present the economic properties of the cost models which include economies of size, schedule, learning curve and process improvement, and economic externalities. The concluding section lists the most important cost drivers and comments on each cost model's strengths.

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

NASA Astrophysics Data System (ADS)

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.

Space station architectural elements model study  

NASA Technical Reports Server (NTRS)

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

Modeling utilization distributions in space and time.  

PubMed

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. PMID:19694144

The international space station: An opportunity for industry-sponsored global education  

NASA Astrophysics Data System (ADS)

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

AIAA Educator Academy: The Space Weather Balloon Module  

NASA Astrophysics Data System (ADS)

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

Cognitive engineering models in space systems  

NASA Technical Reports Server (NTRS)

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

Project trades model for complex space missions  

NASA Technical Reports Server (NTRS)

A Project Trades Model (PTM) is a collection of tools/simulations linked together to rapidly perform integrated system trade studies of performance, cost, risk, and mission effectiveness. An operating PTM captures the interactions between various targeted systems and subsystems through an exchange of computed variables of the constituent models. Selection and implementation of the order, method of interaction, model type, and envisioned operation of the ensemble of tools rpresents the key system engineering challenge of the approach. This paper describes an approach to building a PTM and using it to perform top-level system trades for a complex space mission. In particular, the PTM discussed here is for a future Mars mission involving a large rover.

Space Weather Models at the CCMC And Their Capabilities  

NASA Technical Reports Server (NTRS)

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

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

NASA Astrophysics Data System (ADS)

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

Multiobject segmentation using coupled shape space models  

NASA Astrophysics Data System (ADS)

Due to noise and artifacts often encountered in medical images, segmenting objects in these is one of the most challenging tasks in medical image analysis. Model-based approaches like statistical shape models (SSMs) incorporate prior knowledge that supports object detection in case of in-complete evidence from image data. In this paper, we present a method to increase information of the object's shape in problematic image areas by incorporating mutual shape information from other entities in the image. This is done by using a common shape space of multiple objects as additional restriction. Two different approaches to implement mutual shape information are presented. Evaluation was performed on nine cardiac images by simultaneous segmentation of the epi- and endocardium of the left heart ventricle using the proposed methods. The results show that the segmentation quality is improved with both methods. For the better one, the average surface distance error is approx. 40% lower.

Model space truncation in shell-model fits  

E-print Network

We carry out an interacting shell-model study of binding energies and spectra in the $sd$-shell nuclei to examine the effect of truncation of the shell-model spaces. Starting with a Hamiltonian defined in a larger space and truncating to the $sd$ shell, the binding energies are strongly affected by the truncation, but the effect on the excitation energies is an order of magnitude smaller. We then refit the matrix elements of the two-particle interaction to compensate for the space truncation, and find that it is easy to capture 90% of the binding energy shifts by refitting a few parameters. With the full parameter space of the two-particle Hamiltonian, we find that both the binding energies and the excitation energy can be fitted with remaining residual error about 5% of the average error from the truncation. Numerically, the rms initial error associated with our Hamiltonian is 3.4 MeV and the remaining residual error is 0.16 MeV. This is comparable to the empirical error found in $sd$-shell interacting shell model fits to experimental data\\cite{br06}.

A space radiation test model study  

NASA Astrophysics Data System (ADS)

Dynamic models of the energetic populations in the outer radiation belts are being developed to better understand the extreme variations of particle flux in response to magnetospheric and solar activity. The study utilizes the SCATHA SC3 high energy electron data, covering energies from 47 keV to 5 MeV with fine pitch angle measurements (3 deg field of view) over the L-shell range of 5.3 to 8.7. Butter-fly distributions in the dusk sector signify particle losses due to L shell splitting of the particle drift orbits and the subsequent scattering of the particles from the orbits by the magnetopause. To model the temporal variations and diffusion procsses of the particle populations, the data have been organized into phase space distributions, binned according to altitude (L shell), energy, pitch angle, and time. These distributions can then be mapped to the equator and plotted for fixed first and second adiabatic invariants of the inherent particle motion. A new and efficient method for calculating the third adiabatic invariant using a line integral of the relevant magnetic potential a t the particle mirror points has been developed and is undergoing testing. This method will provide a useful means of displaying the radial diffusion signatures of the outer radiation belts during the more active periods when the L shell parameter is not a good concept due to severe drift-shell splitting. The first phase of fitting the energetic electron phase-space distributions with a combined radial and pitch-angle diffusion formulation is underway.

These are considered useful not only for scientists and engineers but also for the educators and students as a “real textbook”. In space education, we can use several methods to facilitate students' interest. Here we describe some of our examples to promote space education. One is the event accompanying with the major conferences, and second is the video program describing the Hayabusa mission with very unique viewpoint, and the third is the website carefully designed for children. However, the application of mission results to the space education has some points which should be specific to these missions. This paper describes our current attempt of these application and future prospects for the promotion of space education.

A regional model of interprofessional education  

PubMed Central

This paper describes the innovative features of the first regional model of interprofessional education (IPE) in the US, developed by The Commonwealth Medical College, Scranton, PA, USA, as a new, independent, community-based medical school in northeastern Pennsylvania. Essential educational components include collaborative care seminars, interprofessional sessions, simulations, live web-based seminars and newly innovative virtual environment interactive exercises. All of these elements are being integrated into the curricula of 14 undergraduate and allied professional schools, and three graduate medical education programs located in the region. Activities incorporate simulation, standardized patients, student leadership, and faculty and student facilitation. As this new regional model of interprofessional education is fully implemented, its impact will be assessed using both quantitative and qualitative outcomes measurements. Appropriate ongoing modifications to the model will be made to ensure improvement and further applicability to collaborative learning. PMID:23745072

E-print Network

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.

Process modelling for Space Station experiments  

NASA Technical Reports Server (NTRS)

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.

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.

Extracting Space Weather Information from Research Models: Opportunities and Challenges  

NASA Technical Reports Server (NTRS)

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.

National Space Science Data Center Information Model  

NASA Astrophysics Data System (ADS)

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.

The Strategies of Modeling in Biology Education  

NASA Astrophysics Data System (ADS)

Modeling, like inquiry more generally, is not a single method, but rather a complex suite of strategies. Philosophers of biology, citing the diverse aims, interests, and disciplinary cultures of biologists, argue that modeling is best understood in the context of its epistemic aims and cognitive payoffs. In the science education literature, modeling has been discussed in a variety of ways, but often without explicit reference to the diversity of roles models play in scientific practice. We aim to expand and bring clarity to the myriad uses of models in science by presenting a framework from philosopher of biology Jay Odenbaugh that describes five pragmatic strategies of model use in the biological sciences. We then present illustrative examples of each of these roles from an empirical study of an undergraduate biological modeling curriculum, which highlight how students used models to help them frame their research question, explore ideas, and refine their conceptual understanding in an educational setting. Our aim is to begin to explicate the definition of modeling in science in a way that will allow educators and curriculum developers to make informed choices about how and for what purpose modeling enters science classrooms.

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.

Global Model Analysis by Parameter Space Partitioning  

ERIC Educational Resources Information Center

To model behavior, scientists need to know how models behave. This means learning what other behaviors a model can produce besides the one generated by participants in an experiment. This is a difficult problem because of the complexity of psychological models (e.g., their many parameters) and because the behavioral precision of models (e.g.,…

A Space Operations Network Alternative: Using the Globally Connected Research and Education Networks for Space-based Science Operations  

NASA Technical Reports Server (NTRS)

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

Fundamental State Space Time Series Models for JEPX Electricity Prices  

NASA Astrophysics Data System (ADS)

Time series models are popular in attempts to model and forecast price dynamics in various markets. In this paper, we have formulated two state space models and tested them for its applicability to power price modeling and forecasting using JEPX (Japan Electric Power eXchange) data. The state space models generally have a high degree of flexibility with its time-dependent state transition matrix and system equation configurations. Based on empirical data analysis and past literatures, we used calculation assumptions to a) extract stochastic trend component to capture non-stationarity, and b) detect structural changes underlying in the market. The stepwise calculation algorithm followed that of Kalman Filter. We then evaluated the two models' forecasting capabilities, in comparison with ordinary AR (autoregressive) and ARCH (autoregressive conditional heteroskedasticity) models. By choosing proper explanatory variables, the latter state space model yielded as good a forecasting capability as that of the AR and the ARCH models for a short forecasting horizon.

Space weather circulation model of plasma clouds as background radiation medium of space environment.  

NASA Astrophysics Data System (ADS)

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

Development, validation and application of numerical space environment models  

NASA Astrophysics Data System (ADS)

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.

The Community Coordinated Modeling Center (CCMC, http://ccmc.gsfc.nasa.gov) was established at the dawn of the new millennium as a long-term flexible solution to the problem of transition of progress in space environment modeling to operational space weather forecasting. CCMC hosts an expanding collection of state-of-the-art space weather models developed by the international space science community. Over the years the CCMC acquired the unique experience in preparing complex models and model chains for operational environment and developing and maintaining custom displays and powerful web-based systems and tools ready to be used by researchers, space weather service providers and decision makers. In support of space weather needs of NASA users CCMC is developing highly-tailored applications and services that target specific orbits or locations in space and partnering with NASA mission specialists on linking CCMC space environment modeling with impacts on biological and technological systems in space. Confidence assessment of model predictions is an essential element of space environment modeling. CCMC facilitates interaction between model owners and users in defining physical parameters and metrics formats relevant to specific applications and leads community efforts to quantify models ability to simulate and predict space environment events. Interactive on-line model validation systems developed at CCMC make validation a seamless part of model development circle. The talk will showcase innovative solutions for space weather research, validation, anomaly analysis and forecasting and review on-going community-wide model validation initiatives enabled by CCMC applications.

Incorporating Space Science Content Into the Undergraduate Curriculum by the NASA Education Forums' Higher Education Working Group  

NASA Astrophysics Data System (ADS)

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.

Validation of nuclear models used in space radiation shielding applications  

SciTech Connect

A program of verification and validation has been undertaken to assess the applicability of models to space radiation shielding applications and to track progress as these models are developed over time. In this work, simple validation metrics applicable to testing both model accuracy and consistency with experimental data are developed. The developed metrics treat experimental measurement uncertainty as an interval and are therefore applicable to cases in which epistemic uncertainty dominates the experimental data. To demonstrate the applicability of the metrics, nuclear physics models used by NASA for space radiation shielding applications are compared to an experimental database consisting of over 3600 experimental cross sections. A cumulative uncertainty metric is applied to the question of overall model accuracy, while a metric based on the median uncertainty is used to analyze the models from the perspective of model development by examining subsets of the model parameter space.

Space Science Cloud: a Virtual Space Science Research Platform Based on Cloud Model  

NASA Astrophysics Data System (ADS)

Through independent and co-operational science missions, Strategic Pioneer Program (SPP) on Space Science, the new initiative of space science program in China which was approved by CAS and implemented by National Space Science Center (NSSC), dedicates to seek new discoveries and new breakthroughs in space science, thus deepen the understanding of universe and planet earth. In the framework of this program, in order to support the operations of space science missions and satisfy the demand of related research activities for e-Science, NSSC is developing a virtual space science research platform based on cloud model, namely the Space Science Cloud (SSC). In order to support mission demonstration, SSC integrates interactive satellite orbit design tool, satellite structure and payloads layout design tool, payload observation coverage analysis tool, etc., to help scientists analyze and verify space science mission designs. Another important function of SSC is supporting the mission operations, which runs through the space satellite data pipelines. Mission operators can acquire and process observation data, then distribute the data products to other systems or issue the data and archives with the services of SSC. In addition, SSC provides useful data, tools and models for space researchers. Several databases in the field of space science are integrated and an efficient retrieve system is developing. Common tools for data visualization, deep processing (e.g., smoothing and filtering tools), analysis (e.g., FFT analysis tool and minimum variance analysis tool) and mining (e.g., proton event correlation analysis tool) are also integrated to help the researchers to better utilize the data. The space weather models on SSC include magnetic storm forecast model, multi-station middle and upper atmospheric climate model, solar energetic particle propagation model and so on. All the services above-mentioned are based on the e-Science infrastructures of CAS e.g. cloud storage and cloud computing. SSC provides its users with self-service storage and computing resources at the same time.At present, the prototyping of SSC is underway and the platform is expected to be put into trial operation in August 2014. We hope that as SSC develops, our vision of Digital Space may come true someday.

Shuttle Space Suit: Fabric/LCVG Model Validation. Chapter 8  

NASA Technical Reports Server (NTRS)

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

NASA Astrophysics Data System (ADS)

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. An updated schedule is available at FINESSEProgram.org

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

NSDL National Science Digital Library

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. AquariusâÂÂs pioneering efforts to deliver the âÂÂmissing pieces of the climate puzzleâ 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 EarthâÂÂs climate. Education products will appear as modules addressing the missionâÂÂs 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.

Modeling and validation of photometric characteristics of space targets oriented to space-based observation.  

PubMed

A modeling and validation method of photometric characteristics of the space target was presented in order to track and identify different satellites effectively. The background radiation characteristics models of the target were built based on blackbody radiation theory. The geometry characteristics of the target were illustrated by the surface equations based on its body coordinate system. The material characteristics of the target surface were described by a bidirectional reflectance distribution function model, which considers the character of surface Gauss statistics and microscale self-shadow and is obtained by measurement and modeling in advance. The contributing surfaces of the target to observation system were determined by coordinate transformation according to the relative position of the space-based target, the background radiation sources, and the observation platform. Then a mathematical model on photometric characteristics of the space target was built by summing reflection components of all the surfaces. Photometric characteristics simulation of the space-based target was achieved according to its given geometrical dimensions, physical parameters, and orbital parameters. Experimental validation was made based on the scale model of the satellite. The calculated results fit well with the measured results, which indicates the modeling method of photometric characteristics of the space target is correct. PMID:23142894

NASA Astrophysics Data System (ADS)

In order to show the advantages of using hydrologic models in R environment, particularly for educational purposes, we have implemented a conceptual rainfall-runoff model, originally written in Fortran language into R. This hydrologic model is used in many scientific studies and operational engineering applications in Austria. The model consisting of a snow, a soil moisture and a flow routing routine and run on a daily time step in a lumped or a semi-lumped way. The R environment allows to compile and use this model on different platforms and operating system, taking advantage of many additional routines already available in R (i.e. visualisation or optimisation tools). In this poster we present a set of examples that are used in a graduate level course on engineering hydrology at the Vienna University of Technology, which include: - Multi-objective calibration of the model; - Manual vs. automatic calibration; - Visualisation of model outputs and efficiencies; - Model application in ungauged catchments; - Operational runoff forecast. The flexibility of R is ideal for education, since students can easily play with the extensive list of existing functionalities and define new functions and extensions.

Probabilistic Modeling of Space Shuttle Debris Impact  

NASA Technical Reports Server (NTRS)

On Feb 1, 2003, the Shuttle Columbia was lost during its return to Earth. As a result of the conclusion that debris impact caused the damage to the left wing of the Columbia Space Shuttle Vehicle (SSV) during ascent, the Columbia Accident Investigation Board recommended that an assessment be performed of the debris environment experienced by the SSV during ascent. A flight rationale based on probabilistic assessment is used for the SSV return-to-flight. The assessment entails identifying all potential debris sources, their probable geometric and aerodynamic characteristics, and their potential for impacting and damaging critical Shuttle components. A probabilistic analysis tool, based on the SwRI-developed NESSUS probabilistic analysis software, predicts the probability of impact and damage to the space shuttle wing leading edge and thermal protection system components. Among other parameters, the likelihood of unacceptable damage depends on the time of release (Mach number of the orbiter) and the divot mass as well as the impact velocity and impact angle. A typical result is visualized in the figures below. Probability of impact and damage, as well as the sensitivities thereof with respect to the distribution assumptions, can be computed and visualized at each point on the orbiter or summarized per wing panel or tile zone.

Evaluation of “The Space Place,” a NASA Integrated, Multi-mission Education and Public Outreach Program  

NASA Astrophysics Data System (ADS)

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.

We reproduce the DIS measurements of the proton structure function at high energy from the dipole model in momentum space. To model the dipole-proton forward scattering amplitude, we use the knowledge of asymptotic solutions of the Balitsky-Kovchegov equation, describing high-energy QCD in the presence of saturation effects. We compare our results with the previous analysis in coordinate space and discuss possible extensions of our approach.

Is space expanding in the Friedmann universe models?  

E-print Network

The interpretation of the expanding universe as an expansion of space has recently been challenged. From the geodesic equation in Friedmann universe models and the empty Milne model, we argue that a Newtonian or special relativistic analysis is not applicable on large scales, and the general relativistic interpretation in terms of expanding space has the advantage of being globally consistent. We also show that the cosmic redshift, interpreted as an expansion effect, containts both the Doppler effect and the gravitational frequency shift.

Propagation of signals in spaces with affine connections and metrics as models of space-time  

E-print Network

The propagation of signals in space-time is considered on the basis of the notion of null (isotropic) vector field in spaces with affine connections and metrics as models of space or of space-time. The Doppler effect is generalized for these types of spaces. The notions of aberration, standard (longitudinal) Doppler effect, and transversal Doppler effect are considered. On their grounds, the Hubble effect appears as Doppler effect with explicit forms of the centrifugal (centripetal) and Coriolis velocities and accelerations. Doppler effect, Hubble effect, and aberration could be used in mechanics of continuous media and in other classical field theories in the same way as the standard Doppler effect is used in classical and relativistic mechanics.

Twelve Years of Education and Public Outreach with the Fermi Gamma-ray Space Telescope  

NASA Astrophysics Data System (ADS)

During the past twelve years, NASA's Fermi Gamma-ray Space Telescope has supported a wide range of Education and Public Outreach (E/PO) activities, targeting K-14 students and the general public. The purpose of the Fermi E/PO program is to increase student and public understanding of the science of the high-energy Universe, through inspiring, engaging and educational activities linked to the mission’s science objectives. The E/PO program has additional more general goals, including increasing the diversity of students in the Science, Technology, Engineering and Mathematics (STEM) pipeline, and increasing public awareness and understanding of Fermi science and technology. Fermi's multi-faceted E/PO program includes elements in each major outcome category: ? Higher Education: Fermi E/PO promotes STEM careers through the use of NASA data including research experiences for students and teachers (Global Telescope Network), education through STEM curriculum development projects (Cosmology curriculum) and through enrichment activities (Large Area Telescope simulator). ? Elementary and Secondary education: Fermi E/PO links the science objectives of the Fermi mission to well-tested, customer-focused and NASA-approved standards-aligned classroom materials (Black Hole Resources, Active Galaxy Education Unit and Pop-up book, TOPS guides, Supernova Education Unit). These materials have been distributed through (Educator Ambassador and on-line) teacher training workshops and through programs involving under-represented students (after-school clubs and Astro 4 Girls). ? Informal education and public outreach: Fermi E/PO engages the public in sharing the experience of exploration and discovery through high-leverage multi-media experiences (Black Holes planetarium and PBS NOVA shows), through popular websites (Gamma-ray Burst Skymap, Epo's Chronicles), social media (Facebook, MySpace), interactive web-based activities (Space Mysteries, Einstein@Home) and activities by amateur astronomers nation-wide (Supernova! Toolkit). This poster highlights various facets of the Fermi E/PO program.

A regressive storm model for extreme space weather  

NASA Astrophysics Data System (ADS)

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.

A space-averaged model of branched structures  

E-print Network

Many biological systems and artificial structures are ramified, and present a high geometric complexity. In this work, we propose a space-averaged model of branched systems for conservation laws. From a one-dimensional description of the system, we show that the space-averaged problem is also one-dimensional, represented by characteristic curves, defined as streamlines of the space-averaged branch directions. The geometric complexity is then captured firstly by the characteristic curves, and secondly by an additional forcing term in the equations. This model is then applied to mass balance in a pipe network and momentum balance in a tree under wind loading.

Avenues for Scientist Involvement in Earth and Space Science Education and Public Outreach (Invited)  

NASA Astrophysics Data System (ADS)

NASA's Science Mission Directorate (SMD) Science Education and Public Outreach (E/PO) Forums are charged with engaging, extending, supporting, and coordinating the community of E/PO professionals and scientists involved in Earth and space science education activities. This work is undertaken to maximize the effectiveness and efficiency of the overall national NASA science education and outreach effort made up of individual efforts run by these education professionals. This includes facilitating scientist engagement in education and outreach. A number of resources and opportunities for involvement are available for scientists involved in - or interested in being involved in - education or outreach. The Forums provide opportunities for earth and space scientists to stay informed, communicate, collaborate, leverage existing programs and partnerships, and become more skilled education practitioners. Interested scientists can receive newsletters, participate in monthly calls, interact through an online community workspace, and attend E/PO strategic meetings. The Forums also provide professional development opportunities on a myriad of topics, from common pre-conceptions in science, to program evaluation, to delivering effective workshops. Thematic approaches, such as Earth Science Week (http://www.earthsciweek.org), and the Year of the Solar System (http://solarsystem.nasa.gov/yss) are coordinated by the Forums; through these efforts resources are presented topically, in a manner that can be easily ported into diverse learning environments. Information about the needs of audiences with which scientists interact - higher education, K-12 education, informal education, and public - are provided by SMD's Audience-Based Working Groups. Their findings and recommendations are made available to inform the activities and products of E/PO providers so they are able to better serve these audiences. Also available is a 'one-stop shop' of SMD E/PO products and resources that can be used in conjunction with E/PO activities, NASA Wavelength (http://nasawavelength.org). Further supporting higher-education efforts, the Forums coordinate a network of science faculty, bringing them together at science conferences to share resources and experiences and to discuss pertinent education research. An online higher education clearinghouse, EarthSpace (http://www.lpi.usra.edu/earthspace), has been developed to provide faculty with news and funding information, the latest education research and resources for teaching undergraduates, and undergraduate course materials, including lectures, labs, and homework. This presentation will explore the Science E/PO Forums' pathways and tools available to support scientists involved in - or interested in being involved in - E/PO.

Modeling and control of flexible space stations (slew maneuvers)  

NASA Technical Reports Server (NTRS)

Large orbiting space structures are expected to experience mechanical vibrations arising from several disturbing forces such as those induced by shuttle takeoff or docking and crew movements. The problem is considered of modeling and control of large space structures subject to these and other disturbing forces. The system consists of a (rigid) massive body, which may play the role of experimental modules located at the center of the space station and flexible configurations, consisting of several beams, forming the space structure. A complete dynamic model of the system was developed using Hamilton's principle. This model consists of radial equations describing the translational motion of the central body, rotational equations describing the attitude motions of the body and several beam equations governing the vibration of the flexible members (platform) including appropriate boundary conditions. In summary, the dynamics of the space structure is governed by a complex system of interconnected partial and ordinary differential equations. Using Lyapunov's approach the asymptotic stability of the space structure is investigated. For asymptotic stability of the rest state (nominal trajectory), feedback controls are suggested. In the investigation, stability of the slewing maneuvers is also considered. Several numerical results are presented for illustration of the impact of coupling and the effectiveness of the stabilizing controls. Some insight is provided into the complexity of modeling, analysis and stabilization of actual space structures.

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

NASA Astrophysics Data System (ADS)

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.

Dynamics Simulation Model for Space Tethers  

NASA Technical Reports Server (NTRS)

This document describes the development of an accurate model for the dynamics of the Momentum Exchange Electrodynamic Reboost (MXER) system. The MXER is a rotating tether about 100-km long in elliptical Earth orbit designed to catch payloads in low Earth orbit and throw them to geosynchronous orbit or to Earth escape. To ensure successful rendezvous between the MXER tip catcher and a payload, a high-fidelity model of the system dynamics is required. The model developed here quantifies the major environmental perturbations, and can predict the MXER tip position to within meters over one orbit.

Fluid modeling for ion scale space plasmas  

NASA Astrophysics Data System (ADS)

Fluid models with first-order finite Larmor radius (FLR) corrections have been known since the early sixties. It however turns out that a correct dispersion relation for oblique Alfvén waves requires FLR corrections of at least second order in an asymptotics based on temporal and spatial scale separation. Supplementing Landau damping, that provides an essential ingredient for a realistic description of Alfvénic turbulence, is moreover delicate as, in these models, the combination of dispersive and dissipative effects can produce spurious instabilities in some parameter regimes. We thus propose a new kind of fluid model, closed at the level of the fourth-rank moments, that combines the advantages of fully-nonlinear large-scale FLR models, with a small-scale regularization where the nongyrotropic contributions of all the retained moments are evaluated consistently with the low-frequency linear kinetic physics, down to transverse scales comparable to or smaller than the ion gyroradius [see Phys. Plasmas 14, 082502 (2007), Phys. Plasmas 19, 082113 (2012)]. This model, which is based on a matching of the FLR expressions derived both from the fluid formalism and from the kinetic theory, is asymptotically valid at large scales. The small-scale "sub-grid" modeling leads to an accurate description of the linear properties of kinetic Alfvén waves and of the mirror instability, but also provides the correct (in the absence of cyclotron resonance) and sufficient dissipation for turbulent simulations, allowing for the development of power law spectra extending to the smallest resolved scale.

Radiation dosimetry and biophysical models of space radiation effects  

NASA Technical Reports Server (NTRS)

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.

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.

The ESA Virtual Space Weather Modelling Centre - Phase 1  

NASA Astrophysics Data System (ADS)

The ESA ITT project (AO/1-6738/11/NL/AT) to develop Phase 1 of a Virtual Space Weather Modelling Centre has the following objectives and scope: 1. The construction of a long term (~10 yrs) plan for the future development of a European virtual space weather modelling centre consisting of a new ‘open’ and distributed framework for the coupling of physics based models for space weather phenomena; 2. The assessment of model capabilities and the amount of work required to make them operational by integrating them in this framework and the identification of computing and networking requirements to do so. 3. The design of a system to enable models and other components to be installed locally or geographically distributed and the creation of a validation plan including a system of metrics for testing results. The consortium that took up this challenge involves: 1)the Katholieke Universiteit Leuven (Prime Contractor, coordinator: Prof. S. Poedts); 2) the Belgian Institute for Space Aeronomy (BIRA-IASB); 3) the Royal Observatory of Belgium (ROB); 4) the Von Karman Institute (VKI); 5) DH Consultancy (DHC); 6) Space Applications Services (SAS). The project started on May 14 2012, and will finish in May 2014. Thus, by the time of the meeting, both Phase 1A and Phase 1B (the development of the prototype) will be finished. The final report will be presented incl. the architecture decisions made, the framework, the current models integrated already as well as the model couplers installed. The prototype VSWMC will be demonstrated.

Prediction of magnetic substorms using a state space model  

NASA Astrophysics Data System (ADS)

Nonlinear dynamical models of the magnetosphere derived from observational time series data using phase space reconstruction techniques have yielded new advances in the understanding of its dynamics. Considering the solar wind-magnetosphere interaction to be a natural input-output system its dynamical features can be reconstructed on the storm time scale by using the method of time delay embedding. Here, fourteen magnetic storm intervals belonging to low/moderate and high solar activity periods are considered and a suitable state space model has designed by performing training and validation tests, for which dawn to dusk electric field (VBz) is chosen as the input, and the AL time series as the output. The percentage of the output variations that is reproduced by the model is termed as fit_model and a higher number of fit_model means a better model. The number of components m used in the state space model is varied from 1-9 and the best prediction is obtained when m=4. The fit_model values of time series used for validation are 67.96, 67.2, 72.44, and 70.89, with m=4. In the present study most of the storms considered are having Dstmax in between -100 and -300 nT, and they can be predicted well with this procedure. To reveal the prediction capability of the proposed state space model the 30 steps ahead outputs for the storm events are generated, which reasonably reproduce the observed values.

Preliminary Shuttle Space Suit Shielding Model. Chapter 9  

NASA Technical Reports Server (NTRS)

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

Space Experiment Module: A new low-cost capability for education payloads  

NASA Technical Reports Server (NTRS)

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.

Space Transportation Operations: Assessment of Methodologies and Models  

NASA Technical Reports Server (NTRS)

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.

Bipartite Finsler Spaces and the Bumblebee Model  

NASA Astrophysics Data System (ADS)

We present a proposal to include Lorentz-violating effects in a gravitational field by means of Finsler geometry. In the Finsler setup, the length of an event depends both on the point and the direction in the spacetime. We briefly review the bumblebee model, where the Lorentz violation is induced by a spontaneous symmetry breaking due to the bumblebee vector field. The main geometrical concepts of Finsler geometry are outlined. Using a finslerian Einstein-Hilbert action we derive the bumblebee action from the bipartite Finsler function with a correction to the gravitational constant.

SOFTCOST - DEEP SPACE NETWORK SOFTWARE COST MODEL  

NASA Technical Reports Server (NTRS)

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.

Modeling of Radiation Risks for Human Space Missions  

NASA Technical Reports Server (NTRS)

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.

Space Weather Around the World: Using Educational Technology to Engage Teachers and Students in Science Research  

NASA Astrophysics Data System (ADS)

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.

Opportunities for Space Science Education Using Current and Future Solar System Missions  

NASA Astrophysics Data System (ADS)

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.

Process modelling for space station experiments  

NASA Technical Reports Server (NTRS)

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.

Development and testing of a mouse simulated space flight model  

NASA Technical Reports Server (NTRS)

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

AIAA Educator Academy - Mars Rover Curriculum: A 6 week multidisciplinary space science based curriculum  

NASA Astrophysics Data System (ADS)

The Curiosity mission has captured the imagination of children, as NASA missions have done for decades. The AIAA and the University of Houston have developed a flexible curriculum program that offers children in-depth science and language arts learning culminating in the design and construction of their own model rover. The program is called the Mars Rover Model Celebration. It focuses on students, teachers and parents in grades 3-8. Students learn to research Mars in order to pick a science question about Mars that is of interest to them. They learn principles of spacecraft design in order to build a model of a Mars rover to carry out their mission on the surface of Mars. The model is a mock-up, constructed at a minimal cost from art supplies. This project may be used either informally as an after school club or youth group activity or formally as part of a class studying general science, earth science, solar system astronomy or robotics, or as a multi-disciplinary unit for a gifted and talented program. The project's unique strength lies in engaging students in the process of spacecraft design and interesting them in aerospace engineering careers. The project is aimed at elementary and secondary education. Not only will these students learn about scientific fields relevant to the mission (space science, physics, geology, robotics, and more), they will gain an appreciation for how this knowledge is used to tackle complex problems. The low cost of the event makes it an ideal enrichment vehicle for low income schools. It provides activities that provide professional development to educators, curricular support resources using NASA Science Mission Directorate (SMD) content, and provides family opportunities for involvement in K-12 student learning. This paper will describe the structure and organization of the 6 week curriculum. A set of 30 new 5E lesson plans have been written to support this project as a classroom activity. The challenge of developing interactive learning activities for planetary science will be explored. These lesson plans incorporate state of the art interactive pedagogy and current NASA Planetary Science materials.

Multifractal models for space-time rainfall downscaling  

NASA Astrophysics Data System (ADS)

It is well know that rainfall fields display fluctuations in space and time that increase as the scale of observation decreases. Multifractal theory represents a solid base to characterize scale-invariance properties observed in rainfall fields as well as to develop downscaling models able to reproduce observed statistics. The availability of such downscaling tools allows forecasting of floods in small basins by coupling meteorological and hydrological models working on different space-time grid resolution. In this talk multifractal theory will be reviewed highlighting the most relevant aspects for rainfall downscaling (e.g., the concept of scale-invariance in rainfall fields displaying space-time self-similarity or self-affinity, the role of orography). The main results of the scale-invariance analysis of rainfall retrieved by remote sensors will be discussed. Finally the application of multifractal models for rainfall downscaling will be presented and some new ideas for ensemble verification will be argued.

Amateur Radio on the International Space Station (ARISS) - the First Educational Outreach Program on ISS  

NASA Astrophysics Data System (ADS)

More than 40 missions over five years will be required to assemble the International Space Station in orbit. The astronauts and cosmonauts will work hard on these missions, but they plan to take some time off for educational activities with schools. Amateur Radio on the International Space Station represents the first Educational Outreach program that is flying on ISS. NASA's Division of Education is a major supporter and sponsor of this student outreach activity on the International Space Station. This meets NASA's educational mission objective: "To inspire the next generation of explorers...as only NASA can." As the International Space Station takes its place in the heavens, the amateur radio community is doing its part by helping to enrich the experience of those visiting and living on the station as well as the students on Earth. Through ARISS (Amateur Radio on the International Space Station), students on Earth have a once in a lifetime opportunity--to talk to the crew on-board ISS. Using amateur radio equipment set up in their classroom, students get a first-hand feel of what it is like to live and work in space. Each school gets a 10 minute question and answer interview with the on-orbit crew using a ground station located in their classroom or through a remote ground station. The ARISS opportunity has proven itself as a tremendous educational boon to teachers and students. Through ARISS, students learn about orbit dynamics, Doppler shift, radio communications, and working with the press. Since its first flight in 1983, amateur radio has flown on more than two-dozen space shuttle missions. Dozens of astronauts have used the predecessor program called SAREX (The Space Shuttle Amateur Radio Experiment) to talk to thousands of kids in school and to their families on Earth while they were in orbit. The primary goals of the ARISS program are fourfold: 1) educational outreach through crew contacts with schools, 2) random contacts with the amateur radio public, 3) scheduled contacts with the astronauts' friends and families and 4) ISS-based communications experimentation. By June 2002 over 65 schools have been selected from 10 countries for scheduled contacts with the orbiting ISS crews. Ten or more students at each school ask the astronauts questions. The nature of these contacts embodies the primary goal of the ARISS program -- to excite students' interest in science, technology and amateur radio. This paper will discuss the educational outreach capabilities of ARISS, some of the challenges that the ARISS-international team of volunteers overcame to bring this first educational activity on ISS into operation, and its plans for the future. It will also summarize the networking opportunities which expand each school contact, including local school media events, WorldCom support, MSNBC coverage, and internet access. In addition, educational outreach is extended through joint projects with IMAX-3D, Space Center Houston teacher training, and NASA internet activities.

Weight and the Future of Space Flight Hardware Cost Modeling  

NASA Technical Reports Server (NTRS)

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

I Love My Sun: An Educational Space Weather Outreach Tool for Children and Senior People  

NASA Astrophysics Data System (ADS)

In the present day society, there is a vital need for setting up education and outreach activities in the Space Weather field for creating a healthy environment for the proper development of Space Weather markets along with the fundamental and applied research activities. It is important to educate children about the important role that the Sun has in their lives. This presentation gives an educational outreach tool entitled "I Love My Sun" that has been developed for school children in the approximate age group 7 through 11 years. Its main objective is to make children aware of space weather, the Sun, Sun-Earth relations and how they, the children, are part of this global picture. Children are given a lecture about the Sun; this is preceded and followed by the children drawing a picture of the Sun. The activity was initiated by Y. Tulunay in Ankara, Turkey as national project in the context of the 50th anniversary of Space Age and IHY activities. Since then it has been extended into a spatial (Europe) and temporal dimensions. A metric has been developed to facilitate an objective evaluation of the outcomes of the Events. In this presentation, the background behind the "I Love My Sun" initiative is given and it is described how to perform an "I Love My Sun" event. Impressions and main results from the case studies are given. As a new extension, preliminary examples are also given concerning senior people.

Regional centres for space science and technology education affiliated to the United Nations  

NASA Astrophysics Data System (ADS)

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.

SpaceWire model development technology for satellite architecture.  

SciTech Connect

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

A new analysis of Poincaré dodecahedral space model  

E-print Network

The full three-year WMAP results (WMAP3) reinforce the absence of large-angle correlations at scales greater than 60 degrees. The Poincare dodecahedral space (PDS) model model, which may naturally explain such features, thus remains a plausible cosmological model, despite recent controversy about whether matched circle searches would or would not push the topology beyond the horizon. Here, we have used new eigenmode calculations of the dodecahedral space to predict the cosmic microwave background (CMB) temperature fluctuations in such models, with an improved angular resolution. We have simulated CMB maps and confirmed the expected presence of matching circles. For a set of plausible cosmological parameters, we have derived the angular power spectrum of the CMB up to large wavenumbers. Comparison with the WMAP3 observations confirms a remarkable fit with a PDS model, for a value $\\Omega_0 = 1.018$ of the average total energy density.

Redshift space clustering of galaxies and cold dark matter model  

NASA Technical Reports Server (NTRS)

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.

A virtual manipulator model for space robotic systems  

NASA Technical Reports Server (NTRS)

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.

Nonlinear regime-switching state-space (RSSS) models.  

PubMed

Nonlinear dynamic factor analysis models extend standard linear dynamic factor analysis models by allowing time series processes to be nonlinear at the latent level (e.g., involving interaction between two latent processes). In practice, it is often of interest to identify the phases--namely, latent "regimes" or classes--during which a system is characterized by distinctly different dynamics. We propose a new class of models, termed nonlinear regime-switching state-space (RSSS) models, which subsumes regime-switching nonlinear dynamic factor analysis models as a special case. In nonlinear RSSS models, the change processes within regimes, represented using a state-space model, are allowed to be nonlinear. An estimation procedure obtained by combining the extended Kalman filter and the Kim filter is proposed as a way to estimate nonlinear RSSS models. We illustrate the utility of nonlinear RSSS models by fitting a nonlinear dynamic factor analysis model with regime-specific cross-regression parameters to a set of experience sampling affect data. The parallels between nonlinear RSSS models and other well-known discrete change models in the literature are discussed briefly. PMID:24092487

Analysis of a Radiation Model of the Shuttle Space Suit  

NASA Technical Reports Server (NTRS)

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.

Carbon turnover in pore spaces - CIPS model approach  

NASA Astrophysics Data System (ADS)

The CIPS (Carbon turnover In Pore Spaces) model has been developed to overcome the constraints of conceptual pools and to get a better insight into the nature of carbon stabilization in soil (KUKA, 2007). This pure carbon turnover model was implemented in CANDY (CArbon and Nitrogen Dynamics) model system (Franko, 1995). The CIPS model did overcome the empirical pools taking into account soil structure effects. It is based on quality driven primary stabilisation mechanism (recalcitrance of SOM) and process driven secondary stabilisation mechanism (place of turnover) of SOM in soil. In addition to the division of SOM in the qualitative pools on the basis of chemical measurability, a dependence of the turnover conditions from the location of SOM in pore space is implemented taking into account different turnover conditions in the particular pore space and the accessibility for microbial biomass. The main assumption of the CIPS model is that the biological activity is not evenly distributed through the whole pore space. The pore space classes - micro, meso and macro pores - used in the model are marked by wilting point, field capacity and pore volume as a first approach. Because of the poor aeration in the micro pores they show very low biological activity leading to a strong protection of the carbon localized in this pore space. The biological active time (BAT) concept of the CANDY model was adapted to the CIPS model in order to calculate the distribution of biological activity for each pore space class. The reduction functions of the turnover active time concept of CANDY model, related to soil temperature, soil moisture, soil texture, relative air volume and distance to the soil surface are multiplied by the step width of calendar time producing the transformed time step as total BAT (BATtot). The calculated BATtot corresponds to the time that would be required under optimal conditions in the laboratory to perform the same turnover result as under the given suboptimal conditions. The qualitative pools in CIPS model are fresh organic matter (FOM), microbial biomass (AOM), dissolved organic matter (DOM) and residue organic matter (ROM) which are measurable. FOM pool is split in a soluble (S), labile (L) and resistant (R) part. The FOML and FOMR are only available for the AOM pool in meso or macro pores, because it is assumed that micro pores are too small for these organic matter particles. The FOMS directly feeds the DOM pool, that itself is available to all pore space classes providing a vehicle for matter exchange between them Beside a validation of the CIPS model for long term experiments representing a wide range of soils and site conditions shows that the conceptual pool of inert SOM was an empirical representation of to the amount of carbon situated in micro pores.

Effective Space Quantization in Friedman-Robertson-Walker Models  

E-print Network

Quantum--mechanical operators corresponding to canonical momentum and position of a point--like particle, which follow from the quantum field theory in the general Riemannian space-time, satisfy generally to a deformation of the canonical commutation relations with $c^{-2}$ as the parameter of deformation. For operators of the quasi-Cartesian coordinates in the closed and open Friedman--Robertson--Walker models, the deformation reproduces the spatial part of the well--known Snyder formula for quantization of the Minkowsky space-time. The spatially-flat models are distinguished apart by that the deformation is reduced exactly to the standard canonical commutation relations, which correlates remarkably with the fact of the observed flatness of the Universe. Conditions are briefly discussed for which the deformation could have cosmological manifestations. Key words: quantum mechanics, cosmology, quantized space.

Education  

NASA Astrophysics Data System (ADS)

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.

Radiation Belt Environment Model: Application to Space Weather and Beyond  

NASA Technical Reports Server (NTRS)

Understanding the dynamics and variability of the radiation belts are of great scientific and space weather significance. A physics-based Radiation Belt Environment (RBE) model has been developed to simulate and predict the radiation particle intensities. The RBE model considers the influences from the solar wind, ring current and plasmasphere. It takes into account the particle drift in realistic, time-varying magnetic and electric field, and includes diffusive effects of wave-particle interactions with various wave modes in the magnetosphere. The RBE model has been used to perform event studies and real-time prediction of energetic electron fluxes. In this talk, we will describe the RBE model equation, inputs and capabilities. Recent advancement in space weather application and artificial radiation belt study will be discussed as well.

The National Space Biomedical Research Institute's education and public outreach program: Working toward a global 21st century space exploration society  

NASA Astrophysics Data System (ADS)

Space Exploration educators worldwide are confronting challenges and embracing opportunities to prepare students for the global 21st century workforce. The National Space Biomedical Research Institute (NSBRI), established in 1997 through a NASA competition, is a 12-university consortium dedicated to space life science research and education. NSBRI's Education and Public Outreach Program (EPOP) is advancing the Institute's mission by responding to global educational challenges through activities that: provide teacher professional development; develop curricula that teach students to communicate with their peers across the globe; provide women and minority US populations with greater access to, and awareness of science careers; and promote international science education partnerships. A recent National Research Council (NRC) Space Studies Board Report, America's Future in Space: Aligning the Civil Program with National Needs, acknowledges that "a capable workforce for the 21st century is a key strategic objective for the US space program… (and that) US problems requiring best efforts to understand and resolve…are global in nature and must be addressed through mutual worldwide action". [1] This sentiment has gained new momentum through a recent National Aeronautics and Space Administration (NASA) report, which recommends that the life of the International Space Station be extended beyond the planned 2016 termination. [2] The two principles of globalization and ISS utility have elevated NSBRI EPOP efforts to design and disseminate science, technology, engineering and mathematics (STEM) educational materials that prepare students for full participation in a globalized, high technology society; promote and provide teacher professional development; create research opportunities for women and underserved populations; and build international educational partnerships. This paper describes select EPOP projects and makes the case for using innovative, emerging information technologies to transfer space exploration knowledge to students, engage educators from across the globe in discourse about science curricula, and foster multimedia collaborations that inform citizens about the benefits of space exploration for life on Earth. Special references are made to educational activities conducted at professional meetings in Austria, Canada, France, China, Greece, Italy, Russia, Scotland and Spain.

Nuclear and Neutron Matter Calculations with Different Model Spaces  

E-print Network

In this work we investigate the so-called model-space Brueckner-Hartree-Fock (MBHF) approach for nuclear matter as well as for neutron matter and the extension of this which includes the particle-particle and hole-hole (PPHH) diagrams. A central ingredient in the model-space approach for nuclear matter is the boundary momentum $k_M$ beyond which the single-particle potential energy is set equal to zero. This is also the boundary of the model space within which the PPHH diagrams are calculated. It has been rather uncertain which value should be used for $k_M$. We have carried out model-space nuclear matter and neutron matter calculations with and without PPHH diagrams for various choices of $k_M$ and using several modern nucleon-nucleon potentials. Our results exhibit a saturation region where the nuclear and neutron matter matter energies are quite stable as $k_M$ varies. The location of this region may serve to determine an "optimum" choice for $k_M$. However, we find that the strength of the tensor force has a significant influence on binding energy variation with $k_M$. The implications for nuclear and neutron matter calculations are discussed.

Monte Carlo simulation of the shape space model of immunology  

NASA Astrophysics Data System (ADS)

The shape space model of de Boer, Segel and Perelson for the immune system is studied with a probabilistic updating rule by Monte Carlo simulation. A suitable mathematical form is chosen for the probability of increase of B-cell concentration depending on the concentration around the mirror image site. The results obtained agree reasonably with the results obtained by deterministic cellular automata.

A new rat model simulating some aspects of space flight  

NASA Technical Reports Server (NTRS)

A rat suspension model to simulate the effects of weightlessness was developed by U.S. researchers coincident with U.S. involvement in Cosmos-satellite studies. This paper presents some preliminary data dealing with weight gain, food consumption, and bone formation in the rat model as compared with data from the Cosmos 782 and 936 experiments. It is shown that significant changes in bone formation rates may occur during a space flight lasting only five days.

In science education, students should come to understand the nature and significance of models. In the case of chemistry education it is argued that the present use of models is often not meaningful from the students' perspective. A strategy to overcome this problem is to use an authentic chemical modelling practice as a context for a curriculum unit. The theoretical

Ice Sheet System Model as Educational Entertainment  

NASA Astrophysics Data System (ADS)

Understanding the importance of polar ice sheets and their role in the evolution of Sea Level Rise (SLR), as well as Climate Change, is of paramount importance for policy makers as well as the public and schools at large. For example, polar ice sheets and glaciers currently account for 1/3 of the SLR signal, a ratio that will increase in the near to long-term future, which has tremendous societal ramifications. Consequently, it is important to increase awareness about our changing planet. In our increasingly digital society, mobile and web applications are burgeoning venues for such outreach. The Ice Sheet System Model (ISSM) is a software that was developed at the Jet Propulsion Laboratory/CalTech/NASA, in collaboration with University of California Irvine (UCI), with the goal of better understanding the evolution of polar ice sheets. It is a state-of-the-art framework, which relies on higher-end cluster-computing to address some of the aforementioned challenges. In addition, it is a flexible framework that can be deployed on any hardware; in particular, on mobile platforms such as Android or iOS smart phones. Here, we look at how the ISSM development team managed to port their model to these platforms, what the implications are for improving how scientists disseminate their results, and how a broader audience may familiarize themselves with running complex climate models in simplified scenarios which are highly educational and entertaining in content. We also look at the future plans toward a web portal fully integrated with mobile technologies to deliver the best content to the public, and to provide educational plans/lessons that can be used in grades K-12 as well as collegiate under-graduate and graduate programs.
