Evolution of executive branch space policy making

This paper assesses the impacts that changes in the US presidency have had on the civilian space program during the post-Apollo period. It suggests that the White House has lost influence over space issues relative to other interested sectors. The primary factors causing this are a long-term shift to lower priority for these issues, and an inevitable widening of the scope of influence over this sector of activity. Key post-Apollo decisions are discussed for their substantive content and also for what they reveal about the extent to which the president chose to be involved. These findings have implications across all science and technology issue areas as the USA, in the aftermath of the Cold War, reexamines its post-World War II social contract with science.     

Understanding strategic decision making in the context of international space activities

This paper argues that a better understanding of strategic decision making processes in different space agencies is relevant to the successful carrying out of international cooperative undertakings in space and that this kind of information should be taken into account when decisions are to be made on engaging in a new partnership. In this context, the paper provides a general framework for the study of strategic decision making in space organisations, with particular emphasis on the influence of culture. Additionally, it offers practical examples of how differences in policy priorities, decision making environments and practices amongst space organisations can affect international cooperative endeavours. A particular concern is with the role of national and corporate cultures in creating and reflecting differences between space agencies. In order to gather information on strategic decision making processes in the space sector, a series of 30 interviews was conducted with top decision makers from NASA, ESA and the space organisations of Brazil, France, Canada, Russia, The Netherlands and the UK.     

NASA and the phenomenology of discovery: Vigilance,work conditions,and a renewed space policy

As NASA works to redefine the meaning of its mission, two social scientists apply tools from phenomenology to explore how an agency, on the cusp of new thought, is tasked with discovery. Sources for the analysis include interviews, observations, case files and documents before and after a site visit to Johnson Space Center in Houston, Texas. Findings suggest that NASA should consider creating an internal office of phenomenological inquiry designed to recognize phenomenology at work as a fundamental approach for discovery. A special note of appreciation is extended to NASA for fostering and encouraging access to their organization to observe operations at the side of astronauts in training, engineers and scientists at work, and managers overseeing a Space Shuttle mission.     

UK space policy — a problem of culture

According to the UK government, the announcement in July 1987 of a freeze on the British National Space Centre's (BNSC) budget was based solely on lack of money and the belief that private industry, rather than the state, should fund space activities. In challenging the validity of this view, the author suggests that it has also been used to conceal internal bureaucratic competition and a myopic, market-driven mind-set.     

Near space as a sui generis zone: A tri-layer approach of delimitation

The lack of a legal boundary between air space and outer space has not given rise to significant difficulties in the determination of applicable law with respect to traditional flight craft – aircraft and space objects, due to their separated sphere of activities. But the advent of new flight craft that are capable of operating in the intermediate “near space”, i.e. Near Space Vehicles, would render a clarification of their applicable law and the legal status of the zone requisite. For the purpose of balancing the right of exploration and use of near space and the security interest of subjacent States, this short note proposes a tri-layer approach of delimitation by which near space is established as a sui generis zone reserved exclusively for peaceful purposes, while the space below the upper operative limit of aircraft and that above the lower operative limit of space craft are air space and outer space respectively.     

Dominance in space — a new means of exercising global power?

Sustained criticism of the strategy of nuclear deterrence and technological developments in the military uses of space suggest that nuclear weapons may soon be replaced by control of outer space as the USA and USSR's primary instrument of global power. This article traces the change in perceptions of nuclear weapons policy and assesses the potential of outer space as a means of control, and the plans of the two superpowers for its exploitation, especially in the military sphere. The consequences for Western Europe of a shift from nuclear to space-based weapons as the primary guarantor of national security are also discussed.     

The role of the European parliament in the development of a European union space policy

This paper investigates the role of the European Parliament (EP) in the development of the space policy of the EU (EUSP), an important policy area that has been neglected in the political science and EU studies literature. EUSP is the offspring of the European space policy which started as a purely intergovernmental affair, but gradually acquired a supranational dimension. Although the EP did little to initiate this process, it always supported the involvement of the EU in space, and it used both its formal and informal powers to affect and promote its development. Under the consultation procedure the EP managed to become a conditional agenda setter, and under co-decision an influential legislation maker. The changes it introduced in the European global navigation satellite and Earth observation programmes relate not only to the inter-institutional balance and its controlling powers, but to a series of substantive issues also. Consequently, the activism of the EP has played an important part in the development of the EUSP, even if it was not the main force behind its inception.     

An economic assessment of space solar power as a source of electricity for space-based activities

Those in the space community interested in deploying space solar power (SSP) need to know whether it would make economic sense. This article aims to develop a conceptual model of the economic value of SSP as a source of power to in-space activities, such as spacecraft and space stations. We offer several estimates of the value based on interviews and published data, discuss technological innovations that may compete with or be complementary to SSP, and consider alternative institutional arrangements for government and the private sector to provide SSP.     

From initial ideas to a European plan: GMES as an exemplar of European space strategy

Global Monitoring for Environment and Security (GMES) is an idea which originated during a meeting in Baveno, Italy, in May 1998, which generated a call for Europe to get its act together in the field of environmental monitoring from space, to define a well articulated strategy in this area and to build upon its excellent scientific research community, its proven technical prowess in Earth observation from space and its nascent political will to express its objectives in international fora related to climate change and other global environment topics. While Europe was already active in the most advanced areas of global monitoring, its rather uncoordinated efforts (even within the European Commission) lacked visibility and did not appear to fit into a clearly established strategy. The ‘Baveno initiative’ was an attempt to remedy this situation and find a place within a developing ‘European Strategy for Space’, which requires ESA and the European Union to work more closely together. GMES was extended to include the ‘security’ (in its wider sense) aspects of global monitoring, a move that produced a number of questions and misunderstandings, but which allowed many in Europe to realize that monitoring the activities of the Earth’ land masses, oceans and atmosphere do include a security dimension. GMES will eventually incorporate an implementation plan which will call upon various monitoring techniques, ambitious modelling projects and connections with society's more urgent requirements with respect to environmental protection and prevention or reduction of risks related to natural hazards. This will entail significant efforts to inform the user communities and to convince them of the relevance and usefulness of this initiative. It will also provide a sound basis for the European contribution to the new initiative for improved coordination of strategies and systems for Earth observations called for by the July 2003 Earth Observation Summit.     

An exploration of the effectiveness of artificial mini-magnetospheres as a potential solar storm shelter for long term human space missions

If mankind is to explore the solar system beyond the confines of our Earth and Moon the problem of radiation protection must be addressed. Galactic cosmic rays and highly variable energetic solar particles are an ever-present hazard in interplanetary space.     

Net electric power of concentrating solar mirror systems for application in space as a function of the distance to the sun

The use of solar radiation by means of concentrating solar mirror systems, such as parabolic and spheric configurations, mainly is an engineering problem. A decisive characteristic for the optimisation of a complete system with turboelectric power conversion is the thermal cycle applied. Besides the Carnot process, here taken up into the study as an ideal comparative process, suitable processes for the technological realisation are the Brayton process and the Rankine process. The Brayton process is a typical gas turbine process using only the gaseous phase. The Rankine process is a steam engine process using liquid and gaseous phase.The work in hand shows how such solar systems with turboelectric conversion are optimised with respect to their specific weight (kg/kW_e) and how the distance to the sun as well as technological data enter into the analysis.As expected, the Carnot cycle as an ideal comparative process for both types of systems shows the best results for the optimum specific mass of the system. Regarding the real processes, the Rankine cycle shows more favourable characteristics than the Brayton cycle. The difference of the specific masses of the real processes mainly results from the different thermal conditions at the radiator.The influence of the distance to the sun is as expected. The nearer to the sun the solar power system operates, the better is the optimum specific mass of the system. For distances to the sun between 0.3 and 1.0 AU the spheric system shows a better behaviour than the parabolic system. For distances to the sun greater than 2.0 AU the parabolic system shows better behaviour of the specific weight. In the region between 1 and 2 AU the better optimum specific mass of the system belongs to the technological data used in the analysis.     

Ethological analysis of a polar team in the French Antarctic station Dumont d'Urville as simulation of space teams for future interplanetary missions

This new ethological study focuses on the co-adaptation of the crew's spatial behavior to social isolation in a polar base thus simulating long-term living and working of a space team. The method consisted in drawing the subjects' position (n=13) on an observation map at the midday and evening meals at the Dumont d'Urville French station in Antarctica, daily during the summer campaigns and weekly during the winter-over of the TA46 mission. Quantitative data are presented in geocentric (positions), allocentric (distances) and egocentric (orientations) analyses with an emphasis on three adaptative periods (first 3 months, intermediary 2 months and last 3 months of isolation). Results show a large space occupancy during the first week after arrival and the last week before departure from the polar base, and a team-members' grouping during the winter-over. On the over-all time, the inter-individual distances increase. The social orientations are higher at the beginning than at the end of the mission. Discussion underlies the pertinent use of such ethological indicators collected from polar stations as predictors of well-being and optimal-working of the future orbital and planetary stations users.
