A reappraisal of the Space Shuttle programme

The conventional wisdom holds that the Space Shuttle programme has been a ‘policy failure’ because NASA compromised its original concept in the face of weak political commitment and inadequate funding. However, a detailed reappraisal of the history shows that this reasoning is ambiguous, counterfactual and contrary to experience. Congressional and presidential support for the Shuttle has consistently been generous despite flawed and shifting justifications for the programme advanced by NASA. Among the lessons to be learned are the need for more rigorous congressional oversight and the development of smaller, quicker and independent civil space programmes.     

Creating a UK human spaceflight capability: A modest proposal

Since the beginning of international manned activity in the early 1960s, UK governments have consistently avoided participation in human spaceflight, with its high cost and doubts over the resulting scientific gains generally cited as the reasons for opting out. This has resulted in the UK scientific community having no direct access to microgravity science experiments, while the education establishment has missed out on the gains to be had from scientific and technology inspiration for young people. It also makes realistic involvement in the future international manned exploration of the Moon and the solar system unlikely. A viable, low-cost programme could be implemented in the near future to allow for a modest UK manned access to the International Space Station. This need only cost around £50 million over five years, representing about a 5% increase in the current annual UK civil space budget, with funding sought from government departments, research councils and private industry. Making use of Soyuz commercial flights, the project would allow for two separate 10-day science missions. The small corps of three UK astronauts established for the project would form a modest ‘seed-corn’ for future international orbital, lunar and solar system manned exploration involvement for the UK. The benefits of this project would cover science research, education outreach, industrial employment and involvement in international cooperation in manned exploration of the cosmos, as well as in the microgravity research being undertaken by NASA and others.     

Improved space safety for astronauts

The 2003 Columbia accident demonstrated that spaceflight remains a risky and dangerous human endeavor, yet there have been few ‘unofficial’ investigations into astronaut safety. This report summarizes the findings of one such study by George Washington University's Space & Advanced Communications Research Institute—e.g. that simplicity of design may be better than complexity, that cargo missions would be better carried out robotically and that all new space transportation systems should be developed to common international standards—before examining ways that international cooperation can advance the cause of space safety. In establishing future space safety standards input from a wider range of participants (industry, universities and private research institutes, as well as space agencies, etc.) will need to be sought.     

A new paradigm for international cooperation in space exploration

In announcing a new Vision for the US space program, President George Bush committed the USA to “a long-term human and robotic program to explore the solar system”, via a return to the Moon, leading to exploration of Mars and other destinations. He also stated that other nations would be invited to join the vision. Many other nations have, or are developing, ‘exploration visions’ of their own. The potential for international cooperation therefore exists, both at the vision and program/project levels. This paper, based on Working Group discussions as part of an AIAA space cooperation workshop,¹ presents an approach for maximizing the return on all global investments in space exploration. It proposes an international coordination mechanism through which all these various national activities could be integrated into an inherently global enterprise for space exploration, a ‘virtual program of programs’. Within the context of the coordination, individual activities would utilize the full range of cooperative mechanisms for implementation. A significant benefit of this mode of conducting cooperation is that it would not require the negotiation of complex overarching international agreements as a precondition for initiating international activity.     

Space and modernity: 50 years on

As we celebrate the 50th anniversary of the start of spaceflight and of the initiation of European integration, both these symbols of modernity seem to have stalled. We have learnt that some forms of modernity bore a heavy price, such as environmental issues. The social value of ‘progress’ has changed; this affects the types of programme that publics support. Although prestige may still be important to new spacefaring nations, it is the utility of space technology in solving terrestrial problems that is most important, while economic changes, which have made government funding tighter, have opened the door to private initiatives. As we enter the 21st century, we can still be proud of our achievements in space, but we must understand that the reasons we pursue such activity has changed.     

Impact of unification on German space activities

1991 is one of the most decisive years in the history of German space activities. Not only do major policy decisions have to be taken concerning the continuation of the European programmes Hermes and Columbus — which, due to the heavy involvement of Germany in international cooperation, strongly affect its space policy — but one year after the unification of Germany the country is about to set up its new space programme. This is in fact a ‘new’ programme because for the first time it includes all space activities of the unified Germany.     

Consideration of space activities by the UN general assembly

The thirty-ninth session of the United Nations General Assembly affirmed ‘that complete and general disarmament warrants that outer space should be used exclusively for peaceful purposes and that it shall not become an arena for an arms race’.This text appears in the first of two important resolutions concerning outer space adopted by the General Assembly during its last session. Also in the first resolution, entitled ‘Prevention of an Arms Race in Outer Space’ (A/39/59 of 12 December 1984), the Assembly called upon all states, particularly those with major space capabilities, to contribute actively to the objective of the peaceful uses of outer space and to take immediate measures to prevent an arms race in outer space in the interest of maintaining international peace and security and promoting international cooperation and understanding.     

What next for China in space after Shenzhou?

This article discusses China's ambitions in space now that it seems set to pursue human spaceflight. It suggests that, after sending its astronauts into space, completing orbital rendezvous-docking operations and placing a space lab in orbit, China will focus on the Moon with its Chang’e project. As an emerging space power, China will play a more active role in the international space community through collaboration in areas such as lunar exploration, science operations on the International Space Station, the Galileo Global Navigation Satellite System and the International Geosphere–Biosphere Program (IGBP). In particular, China will vigorously explore new opportunities to expand its cooperation with Russia and ESA to counteract Washington's attempt at containment. Meanwhile, Beijing will continue to follow its self-reliance principle to go its own way in space.     

A new cooperative strategy for space in the twenty-first century

The context within which the major government space programmes of the world are planned and obtain political approval has changed dramatically with the end of the Cold War. International economic competition has become a central issue in international affairs. Economic and political constraints require that space agencies adapt the ambitious plans they put forward in the 1980s to the realities of this decade and beyond. This paper argues that in this changed context, enhanced international space cooperation can make important contributions to advancing the core interests of nations and firms, and that in some situations, increased and more intimate cooperation may be the only way to achieve ambitious space goals. The paper contains a series of policy-oriented findings and recommendations that together comprise a ‘new cooperative strategy’ for space.     

An international remote sensing system: A possibility

There have been growing national capabilities in the observation of Earth from space and a corresponding increase in the global awareness of environmental problems. In response, within the past decade consensus has been reached with respect to the recommendations of Unispace-82, the Principles of Remote Sensing and Agenda 21 of the June 1992 United Nations Conference on Environment and Development (UNCED); the latter was convened ‘to lay the foundation for a global partnership between developing and more industrialized countries, based on mutual needs and common interests, to ensure the future of the planet’. Similarly, the framework for international cooperation in such programmes as the US-led Earth Observing system (EOS) and the International Geosphere-Biosphere Programme (IGBP) have been established. An international remote sensing system that is user-driven may be the next logical step.     

Estimating the life cycle cost of the space exploration initiative

The Space Exploration Initiative (SEI) will take mankind back to the Moon and then to Mars. Preliminary estimates of SEI life cycle cost (LCC) are central to assessing programme alternatives. SEI LCC should be estimated by identifying the additional cost to accomplish the initiative over and above the cost to sustain a ‘base’ of space activities. Results of a study of four SEI alternatives provided SEI LCC cost estimates ranging from $91 billion to $308 billion (constant 1989 US dollars) from 1992 through 2020, depending upon programme philosophy. SEI LCC will be driven by the philosophy and goals of the programme, and, given the goal of ‘permanence’, essentially indeterminate because of the open-ended time horizon.     

Reflections on the quest for international cooperation

Changed political objectives, straitened economic circumstances and an altered balance of capability and expertise in space endeavours have together produced more discussion of the need for international cooperation than ever before, but the meaning of the term has subtly shifted. Insisting on US ‘leadership’ is self-defeating; what is instead firmly desired by the USA's potential partners is a balanced relationship in which each nation makes an identifiable contribution and takes the lead in at least one of a package of projects. If this is going to happen, there must be an international forum or framework in which projects can be discussed and agreed. This in turn requires initiative at governmental level.     

Strategic, technological and ethical aspects of establishing colonies on Moon and Mars

With the vast experience gained by Aerospace Community in the last five decades, the natural future course of action will be to expand Space Exploration. Our understanding of Moon is relatively better with a number of unmanned satellite missions carried out by the leading Space Agencies and manned missions to Moon by USA. Also a number of unmanned satellite missions and surface rover missions were carried out to Mars by those Space agencies generating many new details about Mars. While the future exploration efforts by global community will also be centered obviously on Moon and Mars, it is noteworthy that already NASA had declared its plans for establishing a Surface Base on Moon and developing the technical infrastructure required. Surface Bases on Moon and Mars give rise to a number of strategic, technical and ethical issues both in the process of development, and in the process of establishing the bases. The strategic issues related to Moon and Mars Surface Bases will be centered around development of enabling technologies, cost of the missions, and international cooperation. The obvious path for tackling both the technological development and cost issues will be through innovative and new means of international cooperation. International cooperation can take many forms like—all capable players joining a leader, or sharing of tasks at system level, or all players having their independent programmes with agreed common interfaces of the items being taken to and left on the surface of Moon/Mars. Each model has its own unique features. Among the technical issues, the first one is that of the Mission Objectives—why Surface Bases have to be developed and what will be the activity of crew on Surface Bases? Surface Bases have to meet mainly the issues on long term survivability of humans on the Mars/Moon with their specific atmosphere, gravity and surface characteristics. Moon offers excellent advantages for astronomy while posing difficulties with respect to solar power utilization and extreme temperature variations. Hence the technical challenges depend on a number of factors starting from mission requirements. Obviously the most important technical challenge to be addressed will be in the areas of crew safety, crew survivability, adequate provision to overcome contingencies, and in-situ resource utilization. Towards this, new innovations will be developed in areas such as specialized space suits, rovers, power and communication systems, and ascent and descent modules. The biggest ethical issue is whether humankind from Earth is targeting ‘habitation’ or ‘colonization’ of Moon/Mars. The next question will be whether the in-situ resource exploitation will be only for carrying out further missions to other planets from Moon/Mars or for utilization on Earth. The third ethical issue will be the long term impact of pollution on Moon/Mars due to technologies employed for power generation and other logistics on Surfaces. The paper elaborates the views of the authors on the strategic, technical and ethical aspects of establishing Surface Bases and colonies on Moon and Mars. The underlying assumptions and gray areas under each aspect will be explained with the resulting long-term implications.     

Creating a productive international partnership in the Vision for Space Exploration

When US President George W. Bush on 14 January 2004 announced a new US “Vision for Space Exploration”, he called for international participation in “a journey, not a race”, a call received with skepticism and concern elsewhere. But, after a slow start in implementing this directive, during 2006 NASA has increased the forward momentum of action on the program and of discussions on international cooperation in exploring “the Moon, Mars, and beyond”. There are nevertheless a number of significant top-level issues that must be addressed if a cooperative approach to human space exploration is to be pursued. These include the relationship between utilization of the ISS and the lunar exploration plans, integration of potential partners’ current and future capabilities into the exploration plans, and the evolving space-related intentions of other countries.     

The next giant leap in space

Over the past year, the United Nations Association of the USA (UNA) has conducted a massive programme aimed at involving US citizens directly in shaping US space policy. From early January to mid-May of 1986, thousands of people joined forces in some 90 cities and towns across the USA to examine the prospects for international cooperation and the impact of existing and potential military space activities on civilian cooperation.     

Outer space exploitability: International law and developing nations

This article outlines the principles upon which international space law is based. Space law has been successful so far in benefiting the developing countries without hampering the spacefaring nations. The principal treaty provisions that are of special interest to developing nations are discussed, and issues associated with remote sensing, communications and environmental harms are examined in detail. Since 1967 there has been a sharp change in the focus of legal concern towards ‘taking into account the particular needs of developing countries’, a principle that will be central to arrangements for the equitable sharing of the benefits of exploiting the space environment and its natural resources.     

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.     

Space in Poland—a promising future

Poland has been involved in space activities for some years, specialising in the manufacturing of space instrumentation. Projects are carried out within the framework of international cooperation, with ESA being the main partner. The country's experience and existing potential currently encourage consideration of an expansion of the scope and character of the programmes undertaken, including activities aimed at the commercial market. Early steps have been taken towards establishment of a coordinated and consolidated space programme. Poland also has well-defined interests with regard to the space policy of the European Union.     

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.     

Space development: social and political implications

Far-reaching social and political issues are implicit in any discussion of large-scale space development. This Viewpoint argues that the evolution of appropriate political institutions to deal with these issues is likely to be at least as important as the development of new technology. If large-scale space development is to take place, global international cooperation will be essential and such cooperation will have to be underpinned by enhanced institutional and legal structures. In the shorter term, an appropriate institutional response may be the creation of a World Space Agency. However, in the longer term, we should probably view a world space programme as falling within that class of global concerns that would be most appropriately managed by a federal world government.
