Thoughts on Europe's future in space

Fearing that mistaken decisions may be made, the author offers his comments to clarify the future possibilities for Ariane, Hermes and Columbus. The decisions soon to be taken on the manned spaceflight programme will affect the future of the entire European space programme. The possibilities for air-breathing propulsion are also reviewed.     

Japan's future in space

Japan's Consultative Committee on Long Term Policy was established within the Space Activities Commission to consider how the country's space activities should proceed. The Committee was asked to take a long-term viewpoint, considering the rapid changes in both domestic and overseas space activities. This report is an edited version (and unofficial translation) of the Committee's report, published in May 1987. It outlines the significance of space activities for Japan, considers how they have developed during this century, forecasts development after the year 2000, and presents proposals for the execution of Japan's space development.     

Norway's future in space

Norway has recently published its national long-term plan for space activities (1993–1996) and the main points of this are reproduced here. While telecommunications, positioning and navigation and Earth observation are understandably given a high priority, there is also an emphasis on space transportation and space science, and a belief that Norwegian industry and research institutes are capable of gaining contracts beyond the agreed scope of the country's participation in ESA.

The UK''s future in space

The UK government's recent announcement that the British National Space Centre could not expect a budget increase has prompted much reaction in the press. The Chief Executive of British Aerospace, a leading company in the UK space industry, here offers his views on the country's future role in space.     

The future of space medicine.

In November 2000, the National Aeronautics and Space Administration (NASA) and its partners in the International Space Station (ISS) ushered in a new era of space flight: permanent human presence in low-Earth orbit. As the culmination of the last four decades of human space flight activities. the ISS focuses our attention on what we have learned to date. and what still must be learned before we can embark on future exploration endeavors. Space medicine has been a primary part of our past success in human space flight, and will continue to play a critical role in future ventures. To prepare for the day when crews may leave low-Earth orbit for long-duration exploratory missions, space medicine practitioners must develop a thorough understanding of the effects of microgravity on the human body, as well as ways to limit or prevent them. In order to gain a complete understanding and create the tools and technologies needed to enable successful exploration. space medicine will become even more of a highly collaborative discipline. Future missions will require the partnership of physicians, biomedical scientists, engineers, and mission planners. This paper will examine the future of space medicine as it relates to human space exploration: what is necessary to keep a crew alive in space, how we do it today, how we will accomplish this in the future, and how the National Aeronautics and Space Administration (NASA) plans to achieve future goals.     

Human roles in future space operations.

Mankind has evolved in the biosphere from essentially another animal to the level that his industries and societies are powerful components of the life-cycles of Earth. Terrestrial industrial experience can be extended to the use of matter from the Moon and other non-terrestrial sources to create permanent habitats and industry in space. Space stations in low Earth orbit and small bases on the Moon can be the foci of early space industries for learning how to grow in space with local resources. Several near term and long range research topics appropriate to permanent human occupancy of space are reviewed.
