The ISMA proposal — time for a reappraisal?

The proposal for an International Satellite Monitoring Agency (ISMA) was made by France in 1978. This article looks at the arguments raised against developing an ISMA and reassesses the proposal in the light of current and anticipated developments in the field of verification, and new national space programmes.     

Options for space — proposal for a programme

Because of the physical scale of human operations at present, we need to extend them into the Solar System for sustainability and into interstellar space for knowledge. Stabilizing the population on Earth, as well as reducing poverty, is vital, as is a more environmentally appropriate demographic transition than the historical one. Space assets can contribute most to strategic threats in areas like power and minerals and can also assist global education. Such public interest is important as education, but it is vital to remember that a certain level of precision in materials and engineering is needed before ideas become realizable. The crucial step is to turn the space environment to an open market and override the present government monopoly constraint. As a start, a Center for International Space Industrialization Research (CSIR) is to be set up as a model for the better understanding of the issues involved, thus making a case for strategic investment for space assets.     

Space education policy — a global imperative

The discoveries and knowledge gained from space exploration and technology development are valuable scientific education tools which are not being adequately used in the classroom. Moreover, the increasing application of space technology to everyday life and industry requires a work force educated to be able to work productively in this field and to take advantage of all it has to offer. This article provides a survey of what is presently being done in the field of space education in Europe and the USA. Although encouraging, it is not nearly enough to meet the needs of 21st century society, principally because current efforts lack government or industry support. The author argues that this state of affairs must change, and proposed an international symposium as a first step towards this goal.     

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.     

Sputnik fever — again?

The author offers some comments on the drawbacks of another US-Soviet space race. She compares the relative positions of the USA and the USSR in various areas of space science and technology, and concludes that the USSR does not lead in all areas. More importantly, she argues that it is distressing still to be portraying the superpowers as in a race in space. ‘Sputnik fever’ the first time round showed that a space race does not lead to a strong, long-term US space programme. She argues that cooperation in some areas — perhaps a trip to Mars — could b an alternative.     

Flexbus — an attractive technical solution for small missions

Responding to the demand for a ‘faster, cheaper, better’ implementation of space related services, Domier Satellitensysteme GmbH has established and exercised an approach for the development and production of satellites and the corresponding ground equipment for small missions, referred to as Flexbus. It allows to support space service customers starting from mission engineering via design, development and manufacturing of the necessary hardware, the launch service and ending with the hand-over of the operational system. Flexbus harmonises a modular component concept with a sound design and development approach, as a whole providing the means to offer high quality products in a fairly short time and for competitive pricing. This paper will outline the major features of the Flexbus approach and describe application examples.     

LISA — a study of the ESA cornerstone mission for observing gravitational waves

The primary objective of the Laser Interferometer Space Antenna (LISA) mission is to detect and observe gravitational waves from massive black holes and galactic binaries in the frequency range 10⁻⁴ to 10⁻¹ Hz. This low-frequency range is inaccessible to ground-based interferometers because of the unshieldable background of local gravitational noise and because ground-based interferometers are limited in length to a few km. LISA is an ESA cornerstone mission and recently had a system study (Ref. 1) carried out by a consortium led by Astrium, which confirmed the basic configuration for the payload with only minor changes, and provided detailed concepts for the spacecraft and mission design. The study confirmed the need for a drag-free technology demonstration mission to develop the inertial sensors for LISA, before embarking on the build of the flight sensors. With a technology demonstration flight in 2005, it would be possible to carry out LISA as a joint ESA-NASA mission with a launch by 2010 subject to the funding programmatics. The baseline for LISA is three disc-like spacecraft each of which consist of a science module which carries the laser interferometer payload (two in each science module) and a propulsion module containing an ion drive and the hydrazine thrusters of the AOCS. The propulsion module is used for the transfer from earth escape trajectory provided by the Delta II launch to the operational orbit. Once there the propulsion module is jettisoned to reduce disturbances on the payload. Detailed analysis of thermal and gravitational disturbances, a model of the drag-free control and of the interferometer operation confirm that the strain sensitivity of the interferometer will be achieved.     

Space industry — 10-year survey

Space Policy reprints here the Executive Summary of a report by Euroconsult: World Space Industry Survey: Ten-Year Outlook. It summarizes worldwide trends in space activity as they appeared at the beginning of 1988 and analyses them in terms of their economic, financial and industrial aspects. The analyses are centred on the development of space applications and growth prospects in the corresponding markets for the upcoming 10-year period.     

Space station — the new frontier

The exciting challenge of building a permanent space station has been taken up by the USA, and participation in its development has been offered to the USA's allies. European countries are faced with the dilemma of whether to cooperate or to try to develop an autonomous approach. This article discusses the opportunities for Europe in participating closely in the US project — particularly in providing pressurized modules based on the Columbus programme — and argues that it is an opportunity not to be missed.     

Military computing — the last generation

This article examines the computing requirements of the Strategic Defense Initiative. Dr Din points to the massive software problems inherent in SDI programming requirements, and raises the crucial issue of the potential bypassing of human control in any actual outbreak of hostilities.     

The UN and space — 1989 review

In 1989, the two sub-committees of the UN Committee on the Peaceful Uses of Outer Space (COPUOS) - the Scientific and Technical Sub-Committee and the Legal Sub-Committee - held their 26th and 28th sessions, respectively, at UN Headquarters in New York. They subsequently produced reports which were discussed at the 33rd session of COPUOS in New York from 5 to 15 June 1989. N. Jasentuliyana, Director of the Outer Space Affairs Division at the UN, discusses their work.     

The UN and space — 1990 review

In its 44th session the United Nations passed resolutions endorsing International Space Year and the United Nations Conference on Environment and Development, both scheduled for 1992. Together they provide for global efforts to understand and protect the Earth and its environment. N. Jasentuliyana, Director of the Outer Space Affairs Division at the UN, outlines their significance.     

Commercialization of space — the investment opportunities

This report by Ray Williamson of the US Office of Technology Assessment, looks at the prospects for commercialization of space into the 21st century and discusses the relative benefits of private v government investment. The report is taken from a revised version of an article originally appearing in the October 1982 issue of Futures. A fully updated paper will appear in Michiel Schwarz and Paul Stares (eds), ‘The Exploitation of Space: Policy Trends in the Military and Commercial Uses of Space’ (Butterworths, Guildford, UK, 1985).     

Buying Russian technology — pros and cons for the US programme

A marriage between Russian space technology and US space ambitions was unthinkable only a short time ago, but that potential union is now the talk of the town. With the dizzying pace of changes in US-Russian relationships, what is written here in July 1992 may well have changed by the time this article is published. Nevertheless, a glance at what the Russians are selling, what the USA may want to buy and the major policy issues involved is worth a look. Traditional cooperative ventures remain an important part of US-Russian space relations, but are not the focus of this article.     

CEOS — an example of fruitful international cooperation

This paper reviews the evolution of CEOS (Committee on Earth Observations Satellites) from the early days, where participating agencies were primarily concerned with compatibility issues and space programs were chiefly technology-driven, up to the present, where complementarity of satellite programs and fulfillment of final user needs are the main goals being pursued.It also analyzes the favorable conditions that allowed continuity and evolution of the efforts carried by the Committee, in both the technical and the administrative areas, and granted the results achieved so far.Finally, it addresses the expectations of the Committee about the cooperation and interaction with other international bodies, with national governments and with the private sector, with the final aim of maximizing the benefits that Earth Observations can provide for Science and for the well-being of humanity, in particular the people of less-favored regions of the earth.     

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.     

A US dilemma — satellite remote sensing privatization

NASA's and EOSAT's efforts to keep the USA in the technological forefront of remote sensing have been hampered by budgetary constraints and bickering. This article is a plea for a continued and explicit commitment by the US government to the promotion of the necessary technology and cooperative programmes. Unless the issues are tackled with a sense of urgency, the author argues, the French or Japanese may take over the lead.     

Ukrainian space policy — contributing to national economic development

Following Ukraine's 1991 declaration of independence and the disintegration of the USSR, Ukraine inherited a third of the Soviet Union's space industry. This paper presents an overview of the main features of Ukraine's current policy on the exploitation of this capability as a factor in the transformation of its economy. It illustrates how the policy is being realized in the areas of launch systems, Earth observation, satellite communications and international relations, and concludes that Ukraine's strengths in the space field are counterbalanced by obstacles which must be faced, both within the country and externally.
