In 2009 President Obama proposed a budget for the National Aeronautics and Space Administration (NASA) that canceled the Constellation program and included the development of commercial crew transportation systems into low Earth orbit. This significant move to shift human spaceflight into the private sector sparked political debate, but much of the discourse has focused on impacts to “safety.” Although no one disputes the importance of keeping astronauts safe, strategies for defining safety reveal contrasting visions for the space program and opposing values regarding the privatization of U.S. space exploration. In other words, the debate over commercial control has largely become encoded in arguments over safety. Specifically, proponents of using commercial options for transporting astronauts to the International Space Station (ISS) argue that commercial vehicles would be safe for astronauts, while proponents of NASA control argue that commercial vehicles would be unsafe, or at least not as safe as NASA vehicles. The cost of the spaceflight program, the technical requirements for designing a vehicle, the track record of the launch vehicle, and the experience of the launch provider are all incorporated into what defines safety in human spaceflight. This paper analyzes these contested criteria through conceptual lenses provided by fields of science and technology policy (STP) and science, technology, and society (STS). We ultimately contend that these differences in definition result not merely from ambiguous understandings of safety, but from intentional and strategic choices guided by normative positions on the commercialization of human spaceflight. The debate over safety is better considered a proxy debate for the partisan preferences embedded within the dispute over public or private spaceflight.  相似文献

On 12–14 June 2011, a conference was convened in Prague entitled ”Space Security through the Transatlantic Partnership“, co-sponsored by the European Space Policy Institute (ESPI) and the Prague Security Studies Institute (PSSI). It was the first non-governmental transatlantic conference of its kind dedicated to this topic, attended by over 100 senior space policy officials and high-level representatives of multilateral institutions, NGOs, academia, and industry from Europe, the USA, and Japan. The overarching goal of the conference was to solicit and assess both converging and diverging views on the multifaceted subject of space security and to seek to establish an on-going “Track II” non-governmental process designed to assist with the crafting of a future architecture for the management of this key dimension of space policy on a trilateral, and eventually global, basis. This report summarizes the proceedings.  相似文献

Space Phoenix     
《Space Policy》1988,4(2):143-150
The US federal government is collaborating with a non-profit university consortium and its commercial project managers to develop the Space Shuttle fleet's expended external fuel tanks for scientific and commercial uses in space. Nearly a half dozen years in evolution, the Space Phoenix Program is a private-sector civil space programme with the long-term goal of opening the Earth's space to as many people, organizations and activities as possible, as soon as possible, and at the lowest cost to them as possible. In time it is expected to be a major focus for private-sector activities in space. This report describes how it will work.  相似文献

The International Space Station (ISS) is the result of collaboration between 15 countries [Inter-Governmental Agreement (IGA) between the Governments of Canada, the United States of America, Japan, Russia and ESA member States, concerning co-operation on the civil International Space Station, 1998]. Originally planned as a scientific facility, a shift in policy of the partners has recently occurred towards commercialisation of the Station. This article is a response to this policy shift. Based on a report prepared by a Master of Space Studies class at ISU, it set outs to identify the major constraints in which the potential commercial user must operate and proposes solutions for both commercial user and the partner space agencies to facilitate this commercialisation process. At a time when spacefaring nations face reduced fiscal resources and increasing pressure from their constituencies to justify the huge costs of the ISS, commercialising utilisation seems a logical solution. Clearly, successful commercialisation can help recover some of the development and operating costs of the ISS. The structure of the article is divided into two main parts. The first part proposes new solutions to existing constraint to ISS commercialisation in areas of policy, law, technology and business. Its conclusions are integrated and unified into A New Approach towards ISS commercialisation. This approach is then applied in part two to two case studies: the International Space Satellite Servicing Station (I4S) and protein crystallisation. The article then concludes with a recommended approach to the future of ISS commercialisation.  相似文献

China's opaque politics present particular difficulties for US space policy. Heavily invested in and reliant on space, the US will closely monitor China's burgeoning space program. New space powers, and the increasing use of space generally will further create significant challenges, most particularly to the reliance of states on space for national security. In order to maintain its space capabilities, the US will have to decide between securing this via multilateral and co-operative uses of space, or through trying to maintain a level of dominance over other space actors. While very gradually shifting away from the latter position, Washington's policy choices are complicated by the lack of a clear Chinese space strategy. While the Chinese space program, and its wider intentions, are opaque, tenure of a more cooperative approach course might prove fragile.  相似文献

Private and commercial activity in outer space still poses challenges to space law and policy. Within ‘Project 2001’—a legal research project by the University of Cologne's Institute of Air and Space Law and the German Aerospace Center (DLR)—six international expert working groups examined international and national laws, in order to identify gaps and, where necessary, propose improvements to the present legal framework for private space activities. The results were presented and discussed at an international colloquium in May 2001 in Cologne, Germany, where final conclusions have been drawn. This report presents a summary of the project's work and main conclusions, which are documented in full in a comprehensive book to be published in May 2002.  相似文献

Excellent essays have been recently published on the profitability and the future of space tourism. This paper is intended to supplement the considerations in this field and emphasizes the further potential evolution of commercial personal spaceflights. Indeed, based upon work done at the International Space University (ISU) the oligopolistic character of suborbital space tourism has been linked to marketing and product life cycle (PLC) considerations and has led to the thesis that space tourism as a profitable sector will require a follow-on strategy. Orbital space tourism, on one hand, could become an extension of the PLC but, on the other hand, it is assumed that point-to-point (P2P) commercial space transport will become the long term sustainable market. Without ignoring technical challenges, this paper will mainly concentrate on marketing and commercial aspects of personal spaceflight.  相似文献

Space is now a global business, yet the cost of getting to space is still high. Developing new launch vehicles that are cheaper, safer, and more reliable is the key to both rapid commercial growth and to more and better government uses of space. However, the R&D process leading to new launch vehicles is expensive and technically challenging; the past 50 years have seen many government development programs, but no major technological breakthroughs. Perhaps, it is therefore time to think about other ways of developing new launch vehicles. The best expertise in this field resides primarily with private companies and is spread across many actors and nations. A consortium led by space firms might be a better approach to opening up space in the 21st century. Governments will have to develop new policies treating space as though it were a commercial industry, in particular, relaxing export trade restrictions wherever possible. Issues of dual-use may be outweighed by the rapidly growing widespread availability of launch capabilities. Since new launch vehicles will require large up-front R&D expenditures, government support will continue to be needed to supplement private capital funds. Contributions to this effort should be international. However, difficult it might be in today's security conscious environment to reorient government policy, doing so may offer the most efficient and successful way to break the technological and economic barriers to more reliable access to space.  相似文献

This paper argues the urgent need for a Brazilian National Centre on Space Policy and Law Studies, by laying down the basis for such a centre as a natural step in Brazilian space development. In doing so, it looks at the numbers of specialists in this field working in Brazil space entities—both public and private—and at the basic requirements for such specialists. It also discusses the way the main Brazilian space institutions currently deal with legal and policy challenges in space, and whether their methods are effective. Founding a national centre could provide lessons not only for other countries in Latin America but also for other developing countries.  相似文献

Space weather affects global technological systems and societies. Space weather, or the dynamic conditions on the Sun and in the space environment and their impacts on technological systems, can produce coronal mass ejections, solar energetic particles, and geomagnetic disturbances. These space weather events can cause extreme currents in the electric grid, widespread blackouts, and phone and internet communication failures both in space and within the Earth's atmosphere. Severe space weather can damage satellites used for global positioning, communications, and weather forecasting. It also creates a risk of radiation exposure to astronauts and commercial airline crews and passengers. Accurate forecast knowledge of the space weather threat and timing of events is critical to planning and preparation to minimize socioeconomic impacts. This paper reviews the scope of the space weather threat on the global community today. It describes current international and US public policy initiatives to mitigate risk to infrastructure, public safety, and human life. It examines recent international reports and US federal disaster reduction plans to meet these challenges and provides recommendations to increase public awareness and implement public policies to prepare, prevent, and recover from possible catastrophic failures of commercial and government infrastructures caused by a major space weather event.  相似文献

In fulfilling the National Aeronautics and Space Administration's (NASA) responsibility to encourage the fullest commercial use of space the Space Product Development (SPD) Program, within the Microgravity Research Program Office (MRPO) located at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama, is managing an organization of Commercial Space Centers (CSC's) that have successfully employed methods for encouraging private industries to exploit the benefits of space-based research. Unique research opportunities of the space environment are being made available to private industry in an effort to develop new, competitive products; create jobs; and enhance the country's quality of life. Over 200 commercial research activities have been conducted in space by the CSC's and their industrial partners during the last several years. The success of this research is evidenced by the increasing amount of industrial participation in commercial microgravity research and the potential products nearing marketability.  相似文献

Europe is faced with several essential policy decisions with regard to the exploitation of space technology. Important issues are: the relations between civilian and military uses of outer space, employment opportunities, industrial and commercial interests, European security and international stability, regional and international cooperation. Concerted action is required for political reasons and in order to achieve the necessary scientific, technological and economic critical masses. Another major policy issue is, therefore, whether Europe should expand its space venture in the framework of a European military space community as proposed by France, through national or bilateral programmes, by participating in the US SDI research, or through NATO, the Independent European Programme Group, the Western European Union, or the European Space Agency.  相似文献

During the next two decades, we will establish the foundation for the 21st century's accomplishments in space. The Space Shuttle vehicle will become the cornerstone for that foundation by providing economical opportunities for space exploration and utilization.Reusability of the Shuttle vehicle is the key to its economy. The major developmental challenges encountered in the Shuttle program are typified by the complexities involved in designing the reusable propulsion and thermal protection subsystems. We successfully met such challenges and are nearing the launch of the first Shuttle orbital flight.Our immediate goal is to enter the Space Shuttle operational phase because only then will we fully understand the unique capabilities of the Shuttle. Concurrent with our effort to begin Shuttle operations are our initial efforts to expand Shuttle capabilities, extending them significantly beyond those of the current baseline system.Shuttle payload capacity and mission-duration capabilities are to increase considerably during the next decade. Just as present Shuttle performance specifications and development timetables were guided by the space program plans and forecasts of the 1960s, so will the development of long-range space programs be determined by our near-future achievements. We anticipate that the Space Shuttle will play a critical role in those achievements.  相似文献

With the enactment of its ‘Basic Space Law’ in 2008, a significant shift occurred in Japan's space policy away from a narrowly circumscribed interpretation of the concept of space for ‘peaceful purposes’ to a broad understanding of space for ‘security’. Viewed in a global context, Japanese space policy appears symptomatic of a broadened and more malleable understanding of space for security purposes, as already advocated by several other leading spacefaring powers, and proponents of this understanding of space for security argue that this is consistent with international standards and the expectations of a ‘normal’ space power. By attempting to redefine understandings of ‘peace’ and ‘security’, however, the Basic Space Law and subsequent direction of Japanese space policy raise complex and ongoing issues over the interpretation of Japan's ‘Peace Constitution’. This article reviews policy and academic discussions of the recent evolution of Japanese space policy in this respect, arguing that greater emphasis on ‘security’ – understood in a deliberately broad sense in policy terms – has been key to articulating and justifying the reformulation and redirection of Japanese space policy, but that this also brings with it room for ambiguity over the exact nature of Japan's space ambitions at both national and regional levels.  相似文献

Colin Hicks CB   《Acta Astronautica》2009,65(11-12):1593-1598
In all developed countries, once it emerged from the amateur era, Space (and especially rocketry) moved on the public agenda because of its potential significance for both the civil and military policies of governments (coupled with its appetite for new money). In the UK the policy treatment of Space broadly paralleled that in other countries until the post-Empire trauma, the burn-out of the White-Hot Technological revolution of Harold Wilson, and the financial crises of the 1970s exhausted the public appetite for large scale publicly funded projects in high technology. The culmination for Space of these pressures came in 1986–1987 when the UK rejected the emerging international consensus and, almost alone, stayed outside the manned space commitments which developed into the International Space Station. In this paper, Colin Hicks will review the UK political developments which led up to the 1986–1987 decision and how the politics and organisation of UK space activity have developed since then to the point where in 2008 a major government review of the UK involvement in manned space was commissioned.  相似文献

The space elevator in the context of current space exploration policy   总被引:2,自引:1,他引:1  
Mark S. Avnet 《Space Policy》2006,22(2):133-139
The space elevator is an advanced space transportation system that someday could replace chemical rockets as humanity's primary means of reaching Earth's orbit. However, before this can occur, a number of enabling technologies will need to be developed, and a variety of economic and policy questions must be addressed. The goal of this paper is to examine the feasibility of the space elevator in the context of current space exploration policy. The paper reviews the space elevator's critical enabling technologies and presents their wide variety of applications. The challenges of funding the space elevator and of building support for the program are discussed. The potential for international cooperation is considered, and the role of the space elevator in the Vision for Space Exploration is examined. The paper argues that each of the space elevator's component technologies ought to be developed independently to meet separate nearer-term objectives. The space elevator should be just one of many applications considered in making decisions to pursue research and development related to each component technology. The enabling technologies, once mature, might eventually be integrated in the construction of a full-scale space elevator from the Earth's surface to geosynchronous orbit and beyond.  相似文献

The human exploration of space is pushing the boundaries of what is technically feasible. The space industry is preparing for the New Space era, the momentum for which will emanate from the commercial human spaceflight sector, and will be buttressed by international solar system exploration endeavours. With many distinctive technical challenges to be overcome, human spaceflight requires that numerous biological and physical systems be examined under exceptional circumstances for progress to be made. To effectively tackle such an undertaking significant intra- and international coordination and collaboration is required. Space life and biomedical science research and development (R & D) will support the Global Exploration Roadmap (GER) by enabling humans to ‘endure’ the extreme activity that is long duration human spaceflight. In so doing the field will discover solutions to some of our most difficult human health issues, and as a consequence benefit society as a whole. This space-specific R&D will drive a significant amount of terrestrial biomedical research and as a result the international community will not only gain benefits in the form of improved healthcare in space and on Earth, but also through the growth of its science base and industry.  相似文献

Assuring the sustainability of space activities   总被引:1,自引:1,他引:0  
The growth of new space systems and the continued creation of orbital debris could in a few years make activities in Earth orbit unsustainable, so finding cost-effective ways to sustain space activities in Earth orbit is essential. Because outer space activities serve the needs of the military–intelligence, civil, and commercial communities, each with their own requirements, creating the necessary international agreements for reaching and maintaining a condition of sustainability will not be easy. This paper summarizes the primary issues for the international space community regarding our future ability to reap the benefit of space systems in Earth orbit. It explores several of the efforts to develop international agreements that would lead to or support the sustainability of space activities and examines the benefits and drawbacks of each approach. In particular, it reviews progress within the UN COPUOS, and examines the EU's proposal for an international Code of Conduct for Outer Space Activities. It also notes the need for states to establish or expand their own space legal infrastructure to conform to the UN treaties and guidelines for space activities.  相似文献

Since the beginning of the Space Age the public was fascinated by the great challenges that needed to be overcome, but also inspired by the potential benefits that might arise from the utilization of space systems. This lecture examines the major technological breakthroughs that were necessary for many of the key space programs to succeed, and postulates the immediate and future benefits to humanity that became evident as a result of these advances. A dozen programs ranging from Sputnik and Apollo to the Global Navigation Satellite System are reviewed in view of the technical challenges in elements such as propulsion, power, structures, computing, guidance and control, spectrum management and payloads. Challenges in the cost of space launch, large structures, debris mitigation, humans in space and commercial promise are discussed and opportunities for improvements in the future are postulated.  相似文献
