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

In the past, space life sciences has focused on gaining an understanding of physiological tolerance to spaceflight, but, for the last 10 years, the focus has evolved to include issues relevant to extended duration missions. In the 21st century, NASA's long-term strategy for the exploration of the solar system will combine the assurance of human health and performance for long periods in space with investigations aimed at searching for traces of life on other planets and acquiring fundamental scientific knowledge of life processes. Implementation of this strategy will involve a variety of disciplines including radiation health, life support, human factors, space physiology and countermeasures, medical care, environmental health, and exobiology. It will use both ground-based and flight research opportunities such as those found in current on-going programs, on Spacelab and unmanned biosatellite flights, and during Space Station Freedom missions. 相似文献

New roles in space for the 21st century: a Uruguayan view 总被引:1,自引:0,他引:1
In the economic and social circumstances of the 21st century globalized world, there is a need to rethink the traditional roles and positions in space of international intergovernmental organizations, states, both developed and developing, and humankind itself. Uruguay provides an example of a non-typical country that has managed to carve an important niche for itself in the field of space law. Although globalization is an irreversible phenomenon, which has had a devastating effect on the weakest countries, following the attacks of 11 September 2001 insecurity has become globalized for everyone. From the point of view of a state such as Uruguay, this crisis must be looked upon as an opportunity to renew and inspire intelligence, education and culture. In this way—and by continuing to argue for a global space organization—it can contribute to making the Space Age an era of global and planetary solidarity for the benefit of humankind. 相似文献

This paper addresses, with examples, the essential need to devise important scientific research questions in order to set the objectives of space missions. However, the crucial objective of the human race is to survive the numerous hazards, both natural and anthropogenic, which may be expected to occur on Earth during the 21st century. With some experts believing that human civilisation may not survive to the end of the century, the main goals for space exploration should first be the preservation of planet Earth as a human habitat and, second, for human beings to settle in another haven, e.g. to colonise Mars. Treating this as an insurance policy, the annual premium for which could be around $16 billion, a globally cooperative plan should now be prepared and agreed. The fundamental message of this article echoes Zubrin's belief that, in order to survive, humanity must become a spacefaring species. 相似文献

Europe has at last started to integrate the assets of its broad set of actors into a comprehensive European Space Strategy. But will this first approach be ambitious enough to strengthen Europe as a global actor? In this contribution, the individuals responsible for strategy in the French and German space agencies seek an answer to this question. They do so by reviewing the historical background to European space efforts, and its role in shaping present-day activities; setting forth a vision of how Europe should proceed in space, and measuring current progress in drafting a European space strategy against this vision. 相似文献

Commercial activities from outer space have largely consisted of satellite communications. Whilst the maritime and land-mobile services can now be regarded as mature, the next growth area is anticipated in the provision of non-safety aeronautical mobile-satellite services, a service which is now poised to expand significantly in an era marked by competition and convergence of communications technologies. This article highlights and analyses pertinent institutional, legal and regulatory issues, describing what the law is, while making recommendations relating to what the current law should become if the rules were changed to accord with good policy. 相似文献

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. 相似文献

Mindful of the growing need for and interest in the law of outer space, the European Centre for Space Law (ECSL) has started a summer school on the subject, where European students receive instruction in the basics of space law from internationally renowned professors and legal experts. In this report the ECSL's Secretary, Valérie Kayser describes the aims and content of the first two courses and assesses its impact. Student expectations have been met but there is scope for improving the academic level, especially in the area of teamwork. 相似文献

The context within which the major government space programmes of the world are planned and obtain political approval has changed dramatically with the end of the Cold War. International economic competition has become a central issue in international affairs. Economic and political constraints require that space agencies adapt the ambitious plans they put forward in the 1980s to the realities of this decade and beyond. This paper argues that in this changed context, enhanced international space cooperation can make important contributions to advancing the core interests of nations and firms, and that in some situations, increased and more intimate cooperation may be the only way to achieve ambitious space goals. The paper contains a series of policy-oriented findings and recommendations that together comprise a ‘new cooperative strategy’ for space. 相似文献

Cooperation is a major theme of international space law but the law and history also recognize the existence of competition and conflict. What are the trend lines in terms of promoting collective goods, commercialization and new military uses of space? An overview of selected major laws and policies, as they relate to cooperation, competition and conflict, combined with a theoretical examination of game theory (zero-sum and non-zero sum games), will enable us to obtain an overall understanding of the space age and the choices that space lawyers and policy makers face in the future. 相似文献

Over the past 40 years, the Lunar Laser Ranging Program (LLRP) to the Apollo Cube Corner (CCR) Retroreflector Arrays (ALLRRA) [1] has supplied almost all of the significant tests of General Relativity. The LLRP has evaluated the PPN parameters, addressed the possible changes in the gravitational constant and the properties of the self-energy of the gravitational field. In addition, the LLRP has provided significant information on the composition and origin of the moon. This is the only Apollo experiment that is still in operation. Initially the ALLRRAs contributed a negligible fraction of the ranging error budget. Over the decades, the ranging capabilities of the ground stations have improved by more than two orders of magnitude. Now, because of the lunar librations, the existing Apollo retroreflector arrays contribute a significant fraction of the limiting errors in the range measurements.The University of Maryland, as the Principal Investigator for the original Apollo arrays, is now proposing a new approach to the Lunar Laser Array technology [2]. The investigation of this new technology, with Professor Currie as Principal Investigator, is currently being supported by two NASA programs and by the INFN-LNF in Frascati, Italy. Thus after the proposed installation during the next lunar landing, the new arrays will support ranging observations that are a factor 100 more accurate than the current ALLRRAs.The new fundamental cosmological physics and the lunar physics [3] that this new Lunar Laser Ranging Retroreflector Array for the 21st Century (LLRRA-21) can provide will be described. In the design of the new array, there are three major challenges: (1) validate the ability to fabricate a CCR of the required specifications, which is significantly beyond the properties of current CCRs, (2) address the thermal and optical effects of the absorption of solar radiation within the CCR, reduce the transfer of heat from the CCR housing and (3) validate an accurate emplacement technique to install the CCR package on the lunar surface. The latter requires a long-term stable relation between the optical center of the array and the deep regolith, that is, below the thermally driven expansion and contraction of the regolith during the lunar day/night cycle. 相似文献

Many eminent space lawyers gathered in Singapore to attend the first space law conference to be held in South East Asia. Topics for discussion—which included commercialization of space activities and its effect on the needs of developing countries, and the legal issues of expanding communications and navigation satellite services—were of particular interest to the region. This report summarizes the presentations in each session and presents the conclusions and recommendations—such as the need for a legal instrument to regulate remote sensing—produced. 相似文献

The policy process of international cooperation in space exploration. including optimistic and pessimistic scenarios for the twenty-first century, is modeled and examined in this study. In the optimistic scenario, international cooperation involves a balanced and interdependent distribution of capabilities between states, their respective national space agencies and communities of space scientists and space engineers. Cooperation is characterized by interstate participation in critical path components and joint research and development. In the pessimistic scenario, international cooperation is structured and dominated politically and economically by powerful states vis-a-vis weaker states. Cooperation is limited to coordination of separate nationally approved projects and augmentation of capabilities in noncritical path components. On the basis of these two scenarios, policy predictions and implications relevant to exploration missions in the twenty-first century, such as a human-tended lunar base and human missions to Mars, are presented and discussed. 相似文献

ISU Summer Session Students 《Space Policy》2001,17(2)
The era of public space travel is approaching faster than most people think, driven by the human desire for adventure, travel and fun, and by the economic motivation for creating a space industry. Before this will happen, advances in engineering, law and policy, and medicine must be made, as well as considering the issues involved in business and management. Public awareness of the possibility must be increased and world-wide excitement about space generated in order to make space tourism a reality. This is a slightly edited version of the executive summary of the design project produced by ISU students at their 2000 Summer Session Programme in Valparaiso, Chile. 相似文献
