With the beginning of space era, a new branch of medicine has arisen and has been developing along with human exploration of outer space. And even though space medicine mainly faces the same problems as traditional medicine--cosmonauts health care and their high efficiency--this branch, has its own features, associated with the unusual factors of space flight, of which weightlessness is the major one. During the development of manned cosmonautics (duration of a human stay in space has reached already 438 days), methods of cosmonauts medical support and monitoring of their condition have been developed, knowledge of human possibilities and methods of process of organism adaptation to various and frequently severe conditions of external environment have increased. All this led to the fact that nowadays space medicine can become useful for improvement of human health care not only in space but also on the Earth. Moreover, the problem of implementation of cosmonautics achievements, and in particular of space medicine, in practice of public health care presents one of the most important issues concerning human health care. It is also connected with public opinion which is more and more concerned about the efficiency of significant expenses on space activities, especially lately. People often are set by the questions: what has space given, what fruits has space research provided to mankind, which results of this research can be used on the Earth already today for improvement of their life, for discussion of many difficult earthly problems? In terms of using cosmonautics possibilities, its achievements for health care and treatment, it is possible to define a few branches, in which purposeful studies are carried out.  相似文献

The system architecture of the Mobile Service System (MSS) forms an integral part of the architecture of the International Space Station (ISS) in which elements interact through data components controlled by their respective element software. Tne element developers produce software components which, subsequent to being validated on their respective elements, are integrated and verified in test environments which are representative of the integrated MSS/ISS system. This is the classical method for integration and verification. If program software requirements are, for various reasons, slow to finalize, the software development process starts later than anticipated, and following the classical development/verification processes, could put the scheduled software deliveries at risk. A new approach to development and verification is needed which must encompass the entire software program from component unit software to fully integrated system software. This paper describes the approach which was taken to perform system hardware/software integration and verification with software components which were essentially incomplete, but were developed in a phased fashion, having mutually compatible functionality. The paper describes the MSS and ISS system architecture, the various software components and an overview of the original integration and verification plan. The paper will then describe the new integration approach which was developed, and discuss the evolution of the various software components in terms of functionality and their phased integration into a system. The paper will conclude by providing a summary of the results of the integration and verification activities, and demonstrate how delivery schedules for the integrated system software were met.  相似文献

"Mount Everest" is a vague name. That is (on the account here defended) there are many portions of reality all of which have equal claims to serve as its referent. We propose a new account of such vagueness in terms of a theory of what we shall call granular partitions. We distinguish different kinds of crisp and non-crisp granular partitions and we describe the relations between them, concentrating especially on spatial examples. In addition, we describe the practice whereby subjects use systems of reference grids as a means for tempering the vagueness of their judgments for example when they say that Libya straddles the Equator or that the meeting will take place between 2 and 3pm. We then demonstrate how the theory of reference partitions can yield a natural account of this practice, which is referred to in the literature as 'approximation'.  相似文献

France and Germany have long been partners in space. However, new attitudes and directions in their respective space programmes are affecting the nature of traditional Franco-German space relations in an evolving European space context. The long-standing partnership is at a juncture and there is a need for a new dialogue to define what future directions the partnership should take. With this in mind, a joint memorandum was initiated by the European Space Policy Institute (ESPI), who prepared it together with the Paris-based Fondation pour la Recherche Stratégique (FRS) and the Institut Français des Relations Internationales (IFRI), as well as the Berlin-based German Stiftung Wissenschaft und Politik (SWP). It reflects on the state of current Franco-German space relations and lays out the issues to be considered by decision makers in both countries to provide a new impetus to the Franco-German partnership.  相似文献

Within the space program of the Federal Republic of Germany the microgravity program in connection with the utilization of SPACELAB constitutes a central task which determines the long-term program concepts and also their relation to German participation in future ESA programs.The scientific preparatory programs under way for some years now have made further progress. Extensive flight experience and valuable scientific results were obtained on the basis of successful rocket pre-programs. The present paper describes the process in which scientific and organisational priorities are being defined for the planning and execution of the experimental programs.In order to obtain a sufficient number of flight opportunities, payloads for SPACE SHUTTLE missions, in particular under the NASA GAS Program, as well as experimental equipment such as the materials laboratory (MSDR) for FSLP are being developed. The German program focuses on preparing a German SPACELAB mission D1 planned for 1985, which is intended to verify the applicability and efficiency of manned research laboratories for industry and the scientific community. A second emphasis is on preparing the use of SHUTTLE-supported re-usable space platforms.  相似文献

As an increasing number of fascinating discoveries within the realm of bioastronomy appear in media headlines, participating scientists continue to pursue ways of insuring the long-term success of the scientific discipline. In an effort to foster cross-disciplinary collaboration, communication, and training for scientists involved in bioastronomy research, a team of scientists and science education professionals have developed a survey to assess (1) the degree to which scientists in bioastronomy define themselves as interdisciplinary scientists, (2) the extent to which scientists identify their needs for professional development opportunities to become more effective interdisciplinary collaborators, and (3) what services and infrastructure the bioastronomy community needs to develop for long-term productive interdisciplinary communication, collaboration, research and training. The results of a survey, distributed at the 2004 Astrobiology Science Conference (held at Moffett Field, CA), serve the bioastronomy science community by providing a sound research baseline that informs decisions and targeted efforts to increase cross-disciplinary communication, gathering information about needed professional development opportunities for scientists, and generating insights for training of the next generation of astrobiologists. Results indicate that members of the community feel that interdisciplinary communication and collaboration can best be supported by (1) increased funding opportunities, (2) scheduled time for collaboration at professional meetings, (3) reduction of concurrent sessions at professional meetings, and (4) creation of professional development opportunities for scientists.  相似文献

During the past decade new questions in science have emerged that require broad inter-disciplinary approaches. ‘Do asteroids and comets cause extinctions?’ and ‘Was there, or is there, life on Mars?’ are just two examples of questions that cut across planetary or astronomical sciences and biological sciences. The re-emergent science of ‘astrobiology’ represents a new synthesis of inter-disciplinary thinking that in many respects bears similarities to what in the 18th and 19th century would have been called ‘Natural Sciences’. But new astrobiology offers the scientific community, including the space community, two important possibilities. First, an opportunity to galvanize diverse scientific disciplines together to answer some fundamental questions on the relationship between life and the cosmic environment and, second, a chance to create a new environment conducive to interdisciplinary thinking. This is in contrast to the general trend that occurred during the 20th century towards increasing specialization in the sciences. During the 21st century astrobiology has the potential to open rich and productive seams of research.  相似文献

Recent events in the International Space Station (ISS) Program have resulted in the necessity to re-examine the research priorities and research plans for future years. Due to both technical and fiscal resource constraints expected on the International Space Station, it is imperative that research priorities be carefully reviewed and clearly articulated. In consultation with OSTP and the Office of Management and budget (OMB), NASA's Office of Biological and Physical Research (OBPR) assembled an ad-hoc external advisory committee, the Biological and Physical Research Maximization and Prioritization (REMAP) Task Force. This paper describes the outcome of the Task Force and how it is being used to define a roadmap for near and long-term Biological and Physical Research objectives that supports NASA's Vision and Mission. Additionally, the paper discusses further prioritizations that were necessitated by budget and ISS resource constraints in order to maximize utilization of the International Space Station. Finally, a process has been developed to integrate the requirements for this prioritized research with other agency requirements to develop an integrated ISS assembly and utilization plan that maximizes scientific output.  相似文献

The 2007 US National Research Council Decadal Survey for Earth Science and Applications from Space was the first consensus perspective produced by the US Earth Science community of the relative priorities among a sequence of 17 satellite missions over the course of the next decade. However, the Decadal Survey only captured the perspective of the science community, leading to questions about the inclusion of broader priorities from constituent communities and stakeholders. We present a stakeholder value network analysis for the NASA/NOAA Earth Observation Program. The analysis includes a rigorous articulation of the needs and objectives of 13 major stakeholders and a complete stakeholder value network with 190 individual “value flows” that capture the interactions between all the stakeholders. It produces a novel stakeholder map, graphically indicating the outputs most likely to create a lasting Earth Science program. The most important value loops and program outputs are used to derive a set of high-level program goals that suggest what NASA and NOAA should do, as well as how they should conduct business. The analysis concludes that international partnerships represent a strong potential partner for certain science missions with greater potential value delivery than currently-prioritized efforts with defense stakeholders and concludes that weather and land-use missions, in addition to climate missions, should be given highest priority; water, human health, and solid Earth missions should be given lower priority based on each science category's potential for delivering value to the entire stakeholder network.  相似文献

The Mars Exploration Program Analysis Group (MEPAG) maintains a standing document that articulates scientific community goals, objectives, and priorities for mission-enabled Mars science. Each of the goals articulated within the document is periodically revisited and updated. The astrobiology-related Goal One, "Determine if life ever arose on Mars," has recently undergone such revision. The finalized revision, which appears in the version of the MEPAG Goals Document posted on September 24, 2010, is presented here.  相似文献

The NASA/White House Vision for Space Exploration is primarily focused on the development of human and robotic systems that will enable ‘discovery-driven’ investigations in areas important to the scientific community: Mars, the solar system's outer moons, and planets orbiting other stars. Such a portfolio can only be realized if NASA is prepared to target investment at opportunities that are most scientifically compelling. NASA's leaders will have to make decisions in subjective and uncertain environments about the relative long-term value of different kinds of scientific discoveries seen as equally important to different groups. A management paradigm of this kind will imply assessment of heterogeneous priorities and management of interdependent and changing requirements. In order to identify the basis and implications of a ‘discovery-driven’ paradigm, this paper surveys the relationship between the Vision's principles and its programmatic content, the objectives of the Vision's scientific focus areas and their interrelationships, and the public context in which science-focused exploration will proceed.  相似文献

Demonstrating performance of the applications of Earth observation satellite-based science data products and services is increasingly a requirement of government research agencies. We present efforts from the NASA-funded Earth Observing System Data and Information System's Synergy Project to measure performance in the development of applications from NASA research and development projects. We summarize challenges in monitoring performance and share our experience in evolving metrics over a 5-year project life. We demonstrate how to adapt project management processes and metrics from the information technology (IT) industry to Earth observation applications research and development. A roadmap for adapting IT processes and developing metrics and examples of quantitative and qualitative metrics are provided. Our findings suggest that designing and implementing these IT metrics will enhance project success, as defined by the degree of penetration of NASA products into the user community and level of non-NASA funding secured.  相似文献

This report on the commercial benefits of space does not seek to cover in depth all user sectors, but rather to establish an overview of what can be expected by users from the use of space. The growth of applications of technology to projects in the space field has been so rapid and broad, that it has overtaken the level of awareness by many sectors of the community of the benefits that space applications can offer. There is therefore a great need to broaden and deepen the level of awareness by many in the world community of what space is all about. These opportunities apply as much to the developing countries of the world as the developed ones.  相似文献

A new experimental approach is discussed in general terms, that can be adopted in the Shuttle/Spacelab era starting in the 1980s for studies in the area of plasma flow interactions with bodies in space. The potential use of the Space Shuttle/Orbiter as a near Earth plasma laboratory for studies in the area of Space Plasma Physics and particularly in the area of Solar-System Plasmas is discussed. This new experimental approach holds great promise for studies in the Supersonic and sub-Alfvenic flow regime which has applications to the motion of natural satellites around their mother planets in the Solar-system (e.g. the satellite Io around the planet Jupiter). A well conceived experimental and theoretical program, can lead to a better physical understanding regarding the validity and range of applicability of using gas-dynamic, kinetic and fluid approaches in describing collisionless plasma flow interactions with bodies in a variety of flow regimes.In addition to the above scientific aspects of the program, significant technological advances can be achieved regarding the interaction of space probes in planetary atmospheres/ionospheres and the reliability of using various plasma diagnostic devices on board spacecraft and large space platforms.  相似文献

There is increasingly broad concern in the USA today about the quality, vibrancy and appeal of science and technical education in general and space education in particular. There needs to be a robust link between the educational community (i.e. the primary and secondary schools as well as colleges and universities) and a well-defined space research and exploration agenda that is strongly supported by the space industry, NASA and other relevant US governmental agencies. Without such a renewal of mission and new goals it will be difficult to re-invigorate and expand quality space education programs. A workshop was therefore convened in 2003 to analyze the problem, discuss new initiatives, organize a survey inviting suggestions from a range of relevant players and draw conclusions on what the USA needs to do to improve space education in the 21st century. Although the focus of this workshop was on space education in the USA the international dimensions of this problem were also addressed and the firm conclusion was reached that similar issues and concerns apply in Europe, Canada, Japan and other spacefaring nations. This article is an edited version of a White Paper subsequently produced to highlight the problem, summarize the proceedings of the workshop and present the results of the survey. Greater clarity in the definition of national space goals, the upgrading of teachers’ skills and an increase in technical scholarships are among the steps recommended.  相似文献

Many important SETI terms are either ambiguously defined or interpreted by different experts differently. Based on the author's experience with astronautical terminology (IAA multilingual space dictionary) a summary of the usual problems connected with an uniform definition of fundamental terms is attempted. In the second part several examples are quoted from the SETI literature—including the terms ETI, SETI and METI themselves, the definition of a habitable zone, of alien life, of an extraterrestrial artifact, of the Drake equation, of the Fermi-paradox, etc. In the third part of the paper a new task for the SETI social sciences community is raised, namely to collect “Lasting Universal Terms”; i.e. terms the meaning of which did not change since millennia, are independent on geographic position and also on the terrestrial environment and biology. Such terms might be preferably used in interstellar communication. All these questions are related to the manner how we might think about ETI and SETI in new ways. The paper tries to summarize the problems connected with exact SETI terminology and its potential implications for the future.  相似文献

The paper reports research into the transfer of technology typically used in the construction of scientific satellites. Four case studies are analyzed to clarify some basic mechanisms of the transfer of space technology to the industrial system. The paper finds that the technologies analyzed in the construction of satellites for the most part stem from the integration of technical processes already known in various industrial sectors; the use of these processes in space involves their substantial strengthening and upgrading in terms of performance; and this upgrading permits them to return to industrial sectors that use the technological advances acquired for coping with complex problems in the space sector. This research has helped validate some of the determinants of technology transfer already noted in the literature, while increasing the number and content of these. Useful indications emerge for policy makers and agents involved in technology transfer programs.  相似文献
