Increasing global awareness of space activities: World Space Week 2001

This report describes the background to and rationale for World Space Week, now an annual event aiming to increase public awareness of the benefits of peaceful space use and to act as an educational tool for the young. Examples of typical activities in a variety of countries are presented. The report concludes with recommendations—such as rescheduling existing events to the period of World Space Week—to make the event even more successful.     

Recent and future activities of the UN Office for Outer Space Affairs

This article discusses the development, and the current and future work, of the UN Office for Outer Space Affairs. The Office is active both as a source of information, education and training on space and as a secretariat to COPUOS and its Subcommittees; it also performs a role in the monitoring and implementation of various space-related legal treaties. Presently—and as part of the drive to use space to improve life on Earth—the bulk of its work is guided by the Vienna Declaration produced at UNISPACE III.     

Space law conference 2001 : Legal challenges and commercial opportunities for Asia

Many eminent space lawyers gathered in Singapore to attend the first space law conference to be held in South East Asia. Topics for discussion—which included commercialization of space activities and its effect on the needs of developing countries, and the legal issues of expanding communications and navigation satellite services—were of particular interest to the region. This report summarizes the presentations in each session and presents the conclusions and recommendations—such as the need for a legal instrument to regulate remote sensing—produced.     

Space commercialization and the law

This article examines the current legal status of commercial activities in space and describes the legislation — both national and international — existing for their regulation. The question of who is responsible for the action of non-governmental entities is thoroughly discussed, as is the notion of freedom of enterprise. Finally the author looks at the most commercialized areas of space activities — telecommunications and Earth observations — before drawing some conclusions on likely future trends in the privitization and regulation of space activities.     

SPS — time for a pilot plant

Scientists have expended much energy researching SPS but their theories have never yet been realistically tested. It is time for this to change and SPS 2000 — a Japanese-sponsored project to construct and operate a pilot plant to supply electricity to residents of equatorial zones — could provide the means. The project and its benefits are described and the political—economic imperatives for undertaking it presented. The author argues that there are cogent — and practical — reasons for funding a pilot plant, especially given the vast sums spent on other space activities, and on nuclear power, although the latter has never lived up to expectations.     

Possibilities of remote sensing to determine parameters needed for climate change studies

The second objective of GARP—climate research—comes more and more into the focus of the scientific community, and the use of satellites and spacelabs to acquire the necessary data is discussed widely. From an inspection of the results of current climate model computations it is attempted in this paper to deduce the criticality of atmospheric parameters with respect to climate and to deduce the required measuring accuracy to get useful data for further climate studies. It emerges that some quantities as the solar flux and albedo have to be determined to better than 1%, and that much improved global information about particles, clouds and gas distribution is necessary. The impact of these requirements on future satellite systems is discussed. One result is the need for comparative and calibrating spacelab missions as well as for adequate ground truth or in situ operations.     

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.     

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.     

Legal consequences of a SETI detection

If a detection of ETI takes place, this will in all probability be the result of either: (a) detecting and recognising a signal or other emission of ETI; or (b) the finding of an alien artifact (for instance on the Moon or other Celestial Body of our Solar System); or (c) the highly improbable event of an actual encounter. First and foremost, legal consequences regarding any of these contingencies will result from immediate consultations between nations on Earth. Understandings, memoranda and even agreements might be proposed and/or concluded. Such results within the field of terrestrial law will surely be a new branch of International Law, and particularly of International Space Law. At the same time, terrestrial nations will have to realize that any ETI will be self-determined intelligent individualities or organizations who might have their own understanding of “rules of behaviour” and thus, be legal subjects. Whether one calls such rules “law” or not: if two intelligent races—both of which have specific rules of behaviour—come into contact with each other, the basic understanding of such mutual rules will lead to a kind of “code of conduct”. This might be the starting point for a kind of Law—Metalaw—between different races in the Universe.     

RLV economics: fiscal evaluation of NASA''s reusable launch vehicle effort

The US RLV program aims to stimulate commercial development of a next-generation heavy-lift launcher and lower launch costs by one order of magnitude from the Space Shuttle. This paper discusses the incentives needed to encourage private investment — income tax relief, investment mitigation, financing assistance — in the venture and uses a specifically developed case study model to evaluate their effectiveness. It finds that an R&D tax credit would be the most practical incentive. Directions for future work are provided.     

The extraterrestrial Earth: Antarctica as analogue for space exploration

The polar regions have often been suggested as surrogates for the exploration and colonization of space. In particular, Antarctica's greater isolation makes it a useful analogue. Its features—abiotic, acultural, alien to human habitation—all echo the regions of interest to contemporary exploration, notably the solar system and the deep oceans. But more than a century of Antarctic experience also suggests that exploration will likely resemble the Renaissance's Great Voyages and their outposts rather than become portals for wholesale colonization. These sites will traffic mostly in information—the spices and luxury goods of interest to their sustaining societies.     

The impact of launch vehicle type and size on development cost

The technical development trend of future launch vehicle systems is towards fully reusable systems, in order to reduce space transportation cost. However, different types of launch vehicles are feasible, as there are

• —winged two-stage systems (WTS)

• —ballistic single-stage vehicles (BSS)

• —ballistic two-stage vehicles (BTS)

The performance of those systems is compared according to the present state of the art as well as the development cost, based on the “TRANSCOST-Model”. The development costs are shown versus launch mass (GLOW) and pay-load for the three types of reusable systems mentioned above.It is shown that performance optimization and cost minimization lead to different results. It is more economic to increase the vehicle size for achieving higher performance, instead of increasing technical complexity.Finally it is described that due to the essentially lower launch cost of reusable vehicles it will be feasible to recover the development cost by an amortization charge on the launch cost. This possibility, however, would allow commercial funding of future launch vehicle developments.     

Effects of variable transport properties on thermal Marangoni flows

The effects of temperature dependence of the diffusion coefficients on the solution fields of Thermal Marangoni Flows in micro-gravity is analyzed by using an unsteady—variable mesh—two dimensional—finite difference numerical code to solve the full Navier-Stokes equations.A typical cylindrical floating zone geometry is analyzed and the estimation of the deviations caused by considering a temperature-dependent variable viscosity is verified with respect to the most important field parameters (streamlines, isotherms, isobars, Nusselt heating curves, velocity and temperature profiles).Comparison with TEXUS experiment is finally performed.     

When will we see a Golden Age of Spaceflight?

The supposed parallels between the development of aviation and of spaceflight are not as great as believed. The most significant differences are the public expectation that spaceflight, unlike aviation, is a matter for governments and the notion that, because it is so technically challenging, it must always be expensive. Early aviation was massively spurred on by the offer of lucrative prizes for the achievement of certain feats and by the activities of private barnstormers. The successfully attained X Prize has been the first attempt to do the same for spaceflight. The creation of further prizes could be the best way of promoting greater public involvement in space and commercially developing the sector.     

Europe's space plans and opportunities for cooperation

This is a slightly abridged and edited version of the welcoming speech made by European Commission Vice-President Günter Verheugen at the ‘Winning through co-operation: sharing the benefits of space’ conference held in Brussels on 17–18 February 2005 as part of European Space Week. The importance of space for Europe across many areas—now explicitly acknowledged by the European Commission—is highlighted. Future initiatives are discussed and the Union's approach to international cooperation is outlined. It was hoped that the conference would provide an opportunity for participants to identify the best opportunities for partnership in space.     

The biosphere 2 project and its potential role in assisting space exploration

Space Biospheres Ventures is developing technologies for its Biosphere 2 project — a 3 acre materially closed ecological system with human habitat, intensive agriculture and five wilderness biomes — and other life-support testbeds for space habitats in microgravity and the Moon and Mars, as well as for ecological research pertinent to the biosphere of Earth. These include soil bed reactors for air purification and biomass production; aquatic waste processing systems; real-time analytic systems; and computer systems of control and management. A space policy pursuing joint Earth and ‘space biospheres’ objectives and implications is discussed.     

A code of ethics for conducting business in outer space

The aim to increase commercial economic activity in space will be facilitated by the introduction of a code of ethics for the businesses involved, something that is now commonplace on Earth. A proposed such code—comprising 12 principles—is presented below. It covers areas such as environmental stewardship of space, the promotion of honest dealings, making safety an important concern, ensuring a free-market economy and disclosure of conflicts of interest or political contributions.     

Forecasting of the Total Electron Content at a Single Location

The autocovariance prediction method previously used for the forecast of VI derived ionospheric characteristics has been used for forecast of one of the most important ionospheric—the total electron content (TEC)—at single locations. Quiet and disturbed conditions at different European stations were studied in regard to clarify the forecasting capabilities of the method for determination of the TEC. The accuracies of the method achieved in dependence on the time range of the forecast are demonstrated.     

The emerging China–EU space partnership: A geotechnological balancer

Through a techno-nationalist lens, this paper will assess the growing China–European Union (EU) space partnership, and its implications for international space cooperation and competition. Techno-nationalism (jishu minzuzhuyi), the idea that technological strength is an effective determinant of national power in a harshly competitive world,³ informs both Chinese and US perceptions of China's space development. Using this lens elevates all space activities—manned, unmanned, military and scientific—to the strategic level. It is our contention that because of the increasing China–EU space partnership, the USA must re-evaluate its approach to China—away from the containment approach, which has thus far predominated, toward an approach which would offer the USA the opportunity to influence and, thereby, decrease the importance of the emerging partnership.     

Military uses of space-ballistic missile defence

Air Vice-Marshal Menaul argues that the creation of a ballistic missile defence (BMD) system — now within the state of the art — would add immeasurably to the concept of deterrence to war at any level. The reality is that space is already an arena for military operations. Through a review of the technological components and capabilities of a layered defence system as envisaged by the US Fletcher Commission, Air Vice-Marshal Menaul argues for Western support to be given to President Reagan's Strategic Defence Initiative (SDI) and for Europe to begin researching the requirements for a European-based system.
