Earth benefits from space life sciences

Contributions of space exploration which are widely recognized are those dealing with the impact of space technology on public health and medical services in both urban and remote rural areas. Telecommunications, image enhancement, 3-dimensional image reconstructions, miniaturization, automation, and data analysis, have transformed the delivery of medical care and have brought about a new impetus to the field of biomedicine. Many areas of medical care and biological research have been affected. These include technological breakthroughs in such areas as: (1) diagnosis, treatment, and prevention of cardiovascular diseases, (2) new approaches to the understanding of osteoporosis, (3) early detection of genetic birth defects, (4) emergency medical care, and (5) treatment of chronic metabolic disorders. These are but a few examples where technology originally developed to support space medicine or space research has been applied to solving medical and health care delivery problems on Earth.     

Defining a European space research policy: The role of the European Space Science Committee

The willingness of the European Union (EU) to acquire an important position by defining a well articulated space policy for Europe requires a redefinition of the roles of the various actors of this policy. This has been demonstrated at the last ESA Ministerial Conference despite the financial difficulties encountered by all spacefaring European countries. The European Space Science Committee (ESSC), an associated Committee of the European Science Foundation (ESF), actively participated in the elaboration of such a policy by presenting the point of view of the space scientific community and making recommendations to ensure that scientific space research is appropriately accounted for in overall European space policy. The ESSC is briefly described along with its activities and contributions to the definition of a European space policy.     

Commercialization of space activities: Legal requirements constituting a basic incentive for private enterprise involvement

Commercialization of space activities requires a legal framework for private investors and entrepreneurs in order to promote and develop this sector of industry into a fully-fledged commercial enterprise. Apart from the already existing international public legal framework of space law, rules should be created to provide a level playing field for all interested parties. These rules should point to transparency of risks and liabilities and liberalization of the various space market segments. Another legal instrument will be that of dispute resolution among participants in the arena of space activities. For the more distant future the Moon Agreement should be reassessed in the light of resources exploration, management and exploitation against the background of private enterprise involvement.     

Space product development: bringing the benefits of space down to Earth

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.     

Benefits from space technology: A view from a developing country

Space technology has brought unprecedented benefits to humankind, although more for developed than developing countries. The author addresses the role of space technology for developing countries, and how they can choose and develop national space systems for their maximum benefit. International bodies can help them to learn from other countries' experiences through an exchange of information.     

Human interactions in space: results from Shuttle/Mir.

Background: Anecdotal reports from space and results from simulation studies on Earth have suggested that space crewmembers may experience decrements in their interpersonal environment over time and may displace tension and dysphoria to mission control personnel. Methods: To evaluate these issues, we studied 5 American astronauts, 8 Russian cosmonauts, and 42 American and 16 Russian mission control personnel who participated in the Shuttle/Mir space program. Subjects completed questions from subscales of the Profile of Mood States, the Group Environment Scale, and the Work Environment Scale on a weekly basis before, during, and after the missions. Results: Among the crewmembers, there was little evidence for significant time effects based on triphasic (U-shaped) or linear models for the 21 subscales tested, although the presence of an initial novelty effect that declined over time was found in three subscales for the astronauts. Compared with work groups on Earth, the crewmembers reported less dysphoria and perceived their crew environment as more constraining, cohesive, and guided by leadership. There was no change in ratings of mood and interpersonal environment before, during, and after the missions. Conclusions: There was little support for the presence of a moderate to strong time effect that influenced the space crews. Crewmembers perceived their work environment differently from people on Earth, and they demonstrated equanimity in mood and group perceptions, both in space and on the ground. Grant numbers: NAS9-19411.     

Power from space: the policy challenge

The scientific community has long embraced the concept of globalized collaboration, recognizing that scientific inquiry knows no borders and that scientific theory transcends nationality. With respect to translating scientific and technological innovation into practical application, however, national, political, and ideological barriers suddenly arise. At a time when the worlds of economics and finance are rapidly globalizing, the world of applied science lags behind — despite increasingly urgent need for global energy solutions. In the context of considering space solar power (SSP) systems, the author contends that these solutions require new ways of determining costs and benefits; that scientific experts should seek active engagement in the policy arena; and that SSP's scientific community has a critical role to play in advocating for consideration of space-based energy solutions.     

Ensuring equal access to the benefits of space technologies for all countries

There is a concern in the developing world that industrialized countries have not done all they might under Article 1 of the Outer Space Treaty to make the benefits of space technology available to all countries; some are now seeking codification of rights and responsibilities in this sphere. This article discusses recent debate on the issues by COPUOS and its Legal Subcommittee on whether an additional legal framework is necessary to ensure a fairer distribution of benefits. G77 countries were strongly in favour of some form of technology and information transfer, while industrialized countries favoured the existing practice of developing international cooperative space projects. The author believes that a new set of principles will be formulated in the next few years and that organizations like Intelsat and Inmarsat can provide valuable models for ensuring access through cooperative programmes.     

Leadership issues with multicultural crews on the international space station: lessons learned from Shuttle/Mir

In isolated and confined environments, two important leadership roles have been identified: the task/instrumental role (which focuses on work goals and operational needs), and the supportive/expressive role (which focuses on morale goals and emotional needs). On the International Space Station, the mission commander should be familiar with both of these aspects of leadership. In previous research involving a 135-day Mir space station simulation in Moscow and a series of on-orbit Mir space station missions during the Shuttle/Mir program, both these leadership roles were studied. In new analyses of the Shuttle/Mir data, we found that for crewmembers, the supportive role of the commander (but not the task role) related positively with crew cohesion. For mission control personnel on the ground, both the task and supportive roles of their leader were related positively to mission control cohesion. The implications of these findings are discussed in terms of leadership on board the International Space Station.     

EVA 2000: a European/Russian space suit concept

For the European manned space activities an EVA space suit system was being developed in the frame of the Hermes Space Vehicle Programme of the European Space Agency (ESA). The space suit was to serve the needs for all relevant extravehicular activities for the Hermes Columbus operations planned to begin in 2004. For the present Russian manned space programme the relevant EVAs are performed by the Orlan-DMA semi-rigid space suit. The origin of its development reaches back to the 1970s and has since been adapted to cover the needs for extravehicular activities on Salyut and MIR until today. The latest modification of the space suit, which guaranteed its completely self-contained operation, was made in 1988. However, Russian specialists considered it necessary to start developing an EVA space suit of a new generation, which would have improved performance and would cover the needs by the turn of the century and into the beginning of the next century. Potentially these two suit developments could have a lot in common based on similarities in present concepts. As future manned space activities become more and more an international effort, a safe and reliable interoperability of the different space suit systems is required. Based on the results of the Munich Minister Conference in 1991, the European Space Agency and the Russian Space Agency agreed to initiate a requirements analysis and conceptual design study to determine the feasibility of a joint space suit development, EVA 2000. The design philosophy for the EVA 2000 study was oriented on a space suit system design of: space suit commonality and interoperability; increased crew productivity and safety; increase in useful life and reduced maintainability; reduced development and production cost. The EVA 2000 feasibility study was performed in 1992, and with the positive conclusions for EVA 2000, this approach became the new joint European Russian EVA Suit 2000 Development Programme. This paper gives an overview of the results of the feasibility study and presents the joint requirements and the proposed design concept of a jointly developed European Russian space suit.     

The cost benefits of the Spacelab system to scientific investigations and space applications

In the past, one of the major problems in performing scientific investigations in space has been the high cost of developing, integrating, and transporting scientific experiments into space. The limited resources of unmanned spacecraft, coupled with the requirements for completely automated operations, was another factor contributing to the high costs of scientific research in space. In previous space missions after developing, integrating and transporting costly experiments into space and obtaining successful data, the experiment facility and spacecraft have been lost forever, because they could not be returned to earth. The objective of this paper is to present how the utilization of the Spacelab System will result in cost benefits to the scientific community, and significantly reduce the cost of space operations from previous space programs.The following approach was used to quantify the cost benefits of using the Spacelab System to greatly reduce the operational costs of scientific research in space. An analysis was made of the series of activities required to combine individual scientific experiments into an integrated payload that is compatible with the Space Transportation System (STS). These activities, including Shuttle and Spacelab integration, communications and data processing, launch support requirements, and flight operations were analyzed to indicate how this new space system, when compared with previous space systems, will reduce the cost of space research. It will be shown that utilization of the Spacelab modular design, standard payload interfaces, optional Mission Dependent Equipment (MDE), and standard services, such as the Experiment Computer Operating System (ECOS), allow the user many more services than previous programs, at significantly lower costs. In addition, the missions will also be analyzed to relate their cost benefit contributions to space scientific research.The analytical tools that are being developed at MSFC in the form of computer programs that can rapidly analyze experiment to Spacelab interfaces will be discussed to show how these tools allow the Spacelab integrator to economically establish the payload compatibility of a Spacelab mission.The information used in this paper has been assimilated from the actual experience gained in integrating over 50 highly complex, scientific experiments that will fly on the Spacelab first and second missions. In addition, this paper described the work being done at the Marshall Space Flight Center (MSFC) to define the analytical integration tools and techniques required to economically and efficiently integrate a wide variety of Spacelab payloads and missions. The conclusions reached in this study are based on the actual experience gained at MSFC in its roles of Spacelab integration and mission managers for the first three Spacelab missions. The results of this paper will clearly show that the cost benefits of the Spacelab system will greatly reduce the costs and increase the opportunities for scientific investigation from space.     

Taking stock of Europe's developing space policy: from the European space policy workshops to the European space policy forum

A series of workshops designed to make up for the lack of high-level, informal discussion of European space policy has been running—with a gap during formulation of the EC Green/White Paper on this subject—since September 2002. In view of the progress made in establishing a coherent European strategy, and of various other recent events, such as China's entry into the human spaceflight field, the organizers intend not only to continue the series but also to establish a more permanent, research-oriented European Space Policy Foundation (ESPF). Following a report on the proceedings of the third workshop, held in September 2003, which covered developing an overall European policy, new applications (Galileo and GMES) and human spaceflight, the authors set out a proposal for an ESPF and present the six major research themes it would aim to investigate.     

EVA Suit 2000: a joint European/Russian space suit design

A feasibility study in 1992 showed the benefits of a common European Russian space suit development, EVA Suit 2000, replacing the Russian space suit Orlan-DMA and the planned European Hermes EVA space suit at the turn of the century. This EVA Suit 2000 is a joint development initiated by the European Space Agency (ESA) and the Russian Space Agency (RKA). The main objectives of this development program are: first utilization aboard the Russian Space Station MIR-2; performance improvement with respect to current operational suits; development cost reduction. Russian experience gained with the present extravehicular activity (EVA) suit on the MIR Space Station and extensive application of European Technologies will be needed to achieve these ambitious goals. This paper presents the current status of the development activities, the space suit system design and concentrates in more detail on life support aspects. Specific subjects addressed will include the overall life support conceptual architecture, design features, crew comfort and operational considerations.     

Protecting safe access to space: Lessons from the first 50 years of space security

Despite predictions to the contrary at various times from 1957 to 2007, the first 50 years of space security have ended without an arms race or military combat. Arguably, the three riskiest years were 1962, 1983, and 2001. Looking for lessons from these cases, we can identify four primary trends that helped states avoid arms races and direct conflicts in orbit: (1) risks of collective “bads”; (2) fear of action–reaction dynamics; (3) the high cost of space weapons; and (4) the asset of transparency. As we look ahead, trends toward a continued focus on these factors in space security seem strong. But successful prevention of future space warfare will require strengthened forms of individual and collective restraint by all actors in space.     

Some comments on the ESA/EU space strategy

Not only have the European Space Agency (ESA) and the European Union Commission succeeded in producing a joint space strategy within the time set for it, they have created a substantial and worthwhile document which recognises the importance of space for Europe and acknowledges that ESA—not national agencies—is the right body for the conduct of Europe's space efforts. Nevertheless, the strategy's lack of any government financial commitment is a worry— Public–Private Partnerships will never be enough—as is its failure to include any thought for the long term, and in particular manned flight. This critique of the strategy argues for more government spending on space and for greater long-term vision.     

CNES—the way forward: A new strategic plan

This article is based on the French space centre's (CNES) new strategic plan, which marks a shift in strategy. Guided in particular by changed political circumstances and the growing maturity of the space industry, the agency plans to renegotiate its relationships in all major sectors. While the inevitability of European integration and hence cooperation is acknowledged, there is a firm commitment to ensuring that French national and foreign policy is well served.     

Spending without results: lessons from the space station program

The US spent all of the funds originally estimated for the initial development of its orbital space station without producing any significant amount of flight hardware. This article shows how a project with large design costs and significant “non-prime” outlays can quickly deplete program funds. The authors recount the way in which budgetary politics, congressional micro-management, and technological risk conspired to produce this result.     

Forecasting the future in space: Highlights from the TechCast Project

Space technology and activities have changed markedly from the early days of the space era and are continuing to develop rapidly. The TechCast Project—set up to pool the knowledge of experts in the scientific fields—includes space in its predictions. Here its president reports on its space forecasts for the 21st century. The importance of the shift towards the privatization of space is noted and the near-to-medium-term impossibility of interstellar travel conceded. Contact with ETI is deemed much more likely, however.     

Microgravity research results and experiences from the NASA/MIR space station program

The Microgravity Research Program (MRP) participated aggressively in Phase 1 of the International Space Station Program using the Russian Mir Space Station. The Mir Station offered an otherwise unavailable opportunity to explore the advantages and challenges of long duration microgravity space research. Payloads with both National Aeronautics and Space Agency (NASA) and commercial backing were included as well as cooperative research with the Canadian Space Agency (CSA). From this experience, much was learned about long-duration on-orbit science utilization and developing new working relationships with our Russian partner to promote efficient planning, operations, and integration to solve complexities associated with a multiple partner program.

This paper focuses on the microgravity research conducted onboard the Mir space station. It includes the Program preparation and planning necessary to support this type of cross increment research experience; the payloads which were flown; and summaries of significant microgravity science findings.
