Small spacecraft “UNISAT” launched by the “start-1” launcher

The preliminary estimations show that the contemporary level of electronic and information engineering makes it possible to create a small s/c of 150–200 kg mass capable to solve both the problems of Earth remote sensing and many other applied and scientific problems orbiting the planets at 500–1000 km. In accordance with the fundamental criterion for choosing parameters of small multipurpose spacecraft the small UNISAT s/c has been created on the basis of a unified space platform. The design provides for s/c energetic, thermal and space-saving parameters satisfying the conditions for accommodation of various-purpose payload and a possibility of using relatively inexpensive and light launchers like “Start-1” mobile launch complexes. Space platform mass is 100–120 kg; permissible payloads (PL) mass is 40–80 kg; maximal average power consumption of the payload is up to 60 W; three-axes orientation accuracy up to 0.001 deg./s; s/c lifetime is not less than 3–5 years.     

“Space superiority”: Wernher von Braun's campaign for a nuclear-armed space station, 1946–1956

The literature on the history of spaceflight has depicted the early 1950s Collier’s articles mostly as a forerunner to the peaceful and scientific exploration of space. Yet the centerpiece of Wernher von Braun's plan was a manned space station that would serve as reconnaissance platform and orbiting battle station for achieving “space superiority” over the USSR. One its roles could be the launching of nuclear missiles. When challenged as to the station's defensibility, von Braun even posited pre-emptive atomic strikes from space as a response to the development of a hostile anti-satellite capability.     

NEO scientific and policy developments, 1995–2000

Scientific and policy developments in the field of Near-Earth Objects (NEOs) since the UN NEO conference in 1995 are briefly outlined. Some areas of research and discovery have exhibited considerable progress while others have languished. In particular, facilities in the southern hemisphere for discovery and tracking of NEOs are inadequate. Suggestions are made both at the scientific and technical levels as well as at the policy level to provide coordinated and coherent progress in developing a long-term approach to NEO hazard mitigation. The next step should be the establishment of a panel of international scientific experts on the subject.     

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).     

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.     

PFI in the sky, or pie in the sky? — Privatising military space

The UK has made use of dedicated, national military satellites for communications since November 1969. The replacement of the current system, Skynet 4, which will reach the end of its design lifetime early in the next century, is currently under consideration. Possible options which have been mooted to date include a new generation of a national satellite system (Skynet 5), or one of several international collaborative projects. However, these appear to have been superseded by a new possibility — a privately, commercially funded national system under the government's Private Finance Initiative (PFI). This paper examines the historical reliance of the UK on military satellite communications, the options for the next generation of such systems, and, drawing on the UK example, raises a number of questions concerning the potential significance of reliance on commercial enterprise to provide a key element of defence capability.     

The new UK civil space strategy, 2008–2012

The UK civil space strategy for the years 2008–2012 and beyond was published in February 2008. This paper describes the key features of the strategy and highlights those areas that are new or different from the aims set out in previous strategies. In particular, the strategy lays out a new five-part high-level vision for UK civil space.     

Orbiting solar telescope on “Salyut-4” station

The orbiting solar telescope on Salyut-4 (F = 2,5 m, d = 250 mm) produces images of the Sun on the entrance slit of a stigmatic two-grating spectrograph (R₁ = 1 m, N₁ = 1200 lines/mm; R₂ = 0.5 m, N₂ = 2400 lines/mm, dispersion 16 Å/mm, spectral resolution 0,3 Å). The automatic system keeps the observed solar features on the slit of the spectrograph with an accuracy of 3–4 arc sec. The far UV-spectra (970–1400 Å) of solar flares, brightenings, flocculi and prominences were photographed and fresh coatings of mirrors were made during the flight.     

Nanosatellites and micro systems technology — capabilities, limitations and applications

In recent years Micro Systems Technology (MST) was introduced to manufacture miniaturized components for satellite subsystems, like small sensors, valves, micromotors, antennas and many more. These components can be used to build a new class of satellites weighing considerably less than 10 kg, with the capabilities comparable to present microsatellites. With the possibility of cheap mass production of such nanosatellites new applications become possible. However, the construction of very small satellites is connected with problems concerning launch, orbit control and, deorbiting. Furthermore the reduction of size creates certain limits for power consumption, data rates and optical resolutions which have to be carefully considered.     

The growing ‘securitization’ of outer space

Discussions of space security tend to recurrently return to the vexed issue of the ‘militarization’ and ‘weaponization’ of outer space. Debate over whether or not a sustainable definition can be maintained between these two concepts has been a feature of both academic and policy discourses, and has been particularly contentious with regard to new proposals for arms control in outer space. Yet, this paper argues, the militarization/weaponization debate fails to capture to vagaries of contemporary space policy with regard to understandings of ‘security’, and is in this sense an insufficient way of approaching the subject of space security in the first instance. Instead it is now more accurate to say that outer space is becoming ever more ‘securitized’: that is, access to space is now commonly framed as crucial to the military, economic and environmental security of leading states and international organizations.     

The navigational experiments on microgravitational space platform “FOTON-M2”

This paper presents the review of results of the navigating experiments which have been carried out during flight of microgravitational space platform (MSP) Foton-M2 in May–June 2005. The brief characteristic of the created MIRAGE–M equipment consisting from magnitometric system and satellite radionavigation receiver is given. The measurements have allowed to restore unguided MSP movement and to estimate a level of microaccelerations (microgravitations) onboard during flight, and have provided precision time-position binding of the research experiments. The data from the equipments transmitted on the telemetering channel have allowed testing the information technologies of virtual support of experiments in space. Flight testing of the equipment has allowed make a conclusion on usefulness of accommodation onboard the small-sized auxiliary navigating system focused for work with users of research experiments. The experiments on MSP Foton-M2 are the development of experiments with MIRAGE equipment carried out in 1999 during flight time of MSP Foton-12 [N.D. Semkin, V.V. Ivanov, V.I. Abrushkin, V.L.

Surreal estate: addressing the issue of ‘Immovable Property Rights on the Moon’

At a time when scientific and commercial interest in the Moon is being reinvigorated it is becoming fashionable for ordinary individuals to ‘buy’ plots on the lunar surface, with the ‘vendors’ arguing that an absence of specific prohibition of individual private activity in space makes such action legal. It is therefore time for the legal community to address this situation by investigating just how legal such activity is—and bringing their findings to the attention of governments. This can be done through an examination of the relationship between national law and international space law, of the provisions of international space law—especially Article 2 of the Outer Space Treaty—and by answering any claims to private ownership of immovable property. Aside from the fact that individuals appear to be being duped, the pursuit of property claims on the Moon could impede future activities aimed at benefiting society.     

Space as a frontier – the role of human motivation

Despite several false-starts, commercial space is showing signs of activity similar to those in historic frontiers. A comparative study shows a variety of aspects in common; specific environmental enablers that can be labeled technology, legislation and charisma. Charisma can be defined as the human motivation behind frontier activities. Technology and the social systems defined as legislation tend to dominate plans of those engineering frontier activity. However, national, economic and personal ideologies are what drive the frontier. Technology and legislation are the tools by which these ideologies achieve their goals.
