The author discusses the history and current state of space transportation planning, and considers the key issues which will confront the new administration.     

Space activities in Korea—History, current programs and future plans

Korea has participated in space development only since the 1990s. Despite its short history, Korea has been increasing its technological capabilities with the successful experience of several national projects. The Korean government established a long-term space development plan in 1996, which suggests a clear way forward for space development up to 2015. Space activities in Korea will grow continuously. The direction of future space activities will be decided by the national space development plan. This paper discusses Korea's past and present space activities and future development projects.

Exploration for the masses? Or joyrides for the ultra-rich? Prospects for space tourism

A space tourism industry appears to be about to take off. Businesses have announced plans to launch people into suborbital space for $200,000/person, with flights beginning as early as 2008. A brief review of the history of the idea of space tourism over the past four decades—and an awareness that many ventures have quietly shelved their grandiose plans—might aid thinking about the prospects for development of a safe and thriving space tourism industry. Today's space tourism model emphases the concept of luxury, and the lifestyle of hyper-consumption. It may be worth considering whether and how this conception of space tourism might affect the future of space exploration.

Korea''s space development programme: Policy and law

Korea now has a rapidly expanding space programme with exploration aspirations. The government is giving priority to the aerospace industry and, to put it on a better footing, recently enacted a New Space Exploitation Promotion Act. The early history and current and future development of Korea's space activities are briefly described in advance of a comprehensive presentation of the contents of the Act, including launch licensing, liability, registration of space objects, use of satellite information, astronaut rescue, third party liability insurance and establishment of institutions and plans to assist the Korean space effort. A call is made for Asian countries to unite and further their space development through a regional space agency.

Game theory and the law and policy of outer space

Cooperation is a major theme of international space law but the law and history also recognize the existence of competition and conflict. What are the trend lines in terms of promoting collective goods, commercialization and new military uses of space? An overview of selected major laws and policies, as they relate to cooperation, competition and conflict, combined with a theoretical examination of game theory (zero-sum and non-zero sum games), will enable us to obtain an overall understanding of the space age and the choices that space lawyers and policy makers face in the future.

Italian industry's approach to space

European space activities began in the 1960's. The development of what was initially scientific research and which later spread to the enthusiastic involvement of Europe's most advanced industry is by now familiar history. The organization of ELDO and ESRO, which eventually gave way to today's ESA, occured in a span of less than a decade. Many major European countries also commenced their national space programmes during this period. This report examines the space initiatives taken by Italian industry.

Space technology in the third world : Commercialization and the spread of ballistic missiles

The recent enthusiastic initiatives in the USA to commercialize space activities are also likely to facilitate and accelerate Third World ventures in space. This article outlines the history of Third World space activities and points to the danger that these nations will use satellite launch technology for military applications. Competitive economic and political pressures are aiding the migration of older missile technology to Third World Nations. The author argues for the establishment of an International Missile Technology Regime, which would limit the transfer of space launch technology to nations which are in full compliance with the 1968 Nuclear Non-Proliferation Treaty.     

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.

Space policy and the size of the space shuttle fleet

During the space shuttle era, policy makers have repeatedly wrestled with the issue of fleet size. The number of shuttles had both practical and symbolic significance, reflecting the robustness of the space transportation system and US preeminence in space. In debating how many shuttles were needed, NASA and other government entities weighed various arguments to determine the optimum number of vehicles for human spaceflight. Deliberations and decisions about shuttle fleet size reflected changing policy priorities and attitudes about the role of the shuttle. That history frames issues that may arise again in planning for new space transportation vehicles beyond the shuttle.

The European Defence Agency and EU military space policy: Whose space odyssey?

This paper analyses the growing involvement of the European Defence Agency (EA) in the field of space, suggesting that this is symptomatic of the greater importance now being placed on military space by the European Union. It charts the history of the agency in general and its role in space in particular, delineating the many synergetic relations it has with other space-related institutions at EU level. It argues that EDA is as much a response to socioeconomic as strategic considerations, and that it acts to protect European competitiveness in the arms field, thereby highlighting the rising significance of EU military space policy for European security and military institutions.
