International space programmes and policies : N. Jasentuliyana and Ralph Chipman, eds North Holland, Amsterdam and New York, 1984, 552 pp, $65.00

The Second United Nations Conference on the Exploration and Peaceful Uses of Outer Space ( 82) identified crucial problems and made recommendations on strategies for developing countries to bridge the gap with advanced nations in the area of space technology. This article addresses some issues which, although implicit in the Report, are not discussed in detail therein. The role of space science and related scientific research is particularly emphasized. Close attention is paid to the role of human factors, such as the motivation to conduct research, the motivation to engage in international cooperation, and the motivation to utilize and exploit space. Possible opportunities for space research for developing countries, as well as relevant issues concerning management of space, are briefly discussed.     

The participation of developing countries in space research

The Second United Nations Conference on the Exploration and Peaceful Uses of Outer Space (Unispace 82) identified crucial problems and made recommendations on strategies for developing countries to bridge the gap with advanced nations in the area of space technology. This article addresses some issues which, although implicit in the Unispace Report, are not discussed in detail therein. The role of space science and related scientific research is particularly emphasized. Close attention is paid to the role of human factors, such as the motivation to conduct research, the motivation to engage in international cooperation, and the motivation to utilize and exploit space. Possible opportunities for space research for developing countries, as well as relevant issues concerning management of space, are briefly discussed.     

Space policy for late comer countries: A case study of South Korea

Korea’s space development program was created almost 40 years behind those of the advanced countries but it has nevertheless made remarkable progress. Korean space development has been focused on technology catch-up, where commercialization and growth of industrial competitiveness are important rationales. However, the program has several problems, including: lack of a space equipment manufacturing industry, total system companies in the space manufacturing industry and communication between industry and researchers, and much concentration of projects and initiatives in the Korean Aerospace Research Institute (KARI). This study analyzes the problem by comparing space agencies and programs in Korea and other countries, particularly Japan and the USA. It is shown that the role of a national laboratory is critical in space industry development and argued that KARI should make greater efforts to promote the Korean space industry by encouraging technology transfer, sharing equipment and communication between companies. For successful space development, the main organization – usually the national research institute – should change its role from a research-only laboratory to manager and supporter of space development and industry. Such a move would invigorate Korea’s space industry and allow it to catch up with countries with a similar environment.

International space exploration: Cooperative or competitive?

France and the USA have in the past enjoyed a close and fruitful cooperative relationship in space but there is now a growing divergence between apparent US priorities for future activity and those of other countries, for whom human spaceflight is not so important. While accepting that it cannot match the USA technologically, Europe is increasingly sceptical of the wisdom of pursuing space cooperation with its given difficulties caused by the ITAR regime, greater suspicion of anything foreign in the USA and the unwillingness of NASA ever to cede a critical path to a partner. Nor are any of the non-space ventures currently being suggested as cooperation models attractive from a European point of view. A better way forward would be to have conglomerates of nations cooperating on an equal footing and avoiding recourse to US State Department-regulated technology.     

A framework for evaluating national space activity

Space technology and resources are used around the world to address societal challenges. Space provides valuable satellite services, unique scientific discoveries, surprising technology applications and new economic opportunities. Many developing countries formally recognize the advantages of space resources and pursue national level activity to harness them. There is limited data or documentation on the space activities of developing countries. Meanwhile, traditional approaches to summarize national space activity do not necessarily capture the types of activity that developing countries pursue in space. This is especially true if they do not have a formal national space program or office. Developing countries pursue national space activity through activities of many types—from national satellite programs to commercial use of satellite services to involvement with international space institutions. This research aims to understand and analyze these trends. This paper introduces two analytical frameworks for evaluating space activity at the national level. The frameworks are specifically designed to capture the activity of countries that have traditionally been less involved in space. They take a broad view of space related activity across multiple societal sectors and disciplines. The discussion explains the approach for using the frameworks as well as illustrative examples of how they can be applied as part of a research process. The first framework is called the Mission and Management Ladders. This framework considers specific space projects within countries and ranks them on “Ladders” that measure technical challenge and managerial autonomy. This first method is at a micro level of analysis. The second framework is called the Space Participation Metric (SPM). The SPM can be used to assign a Space Participation score to countries based on their involvement in various space related activities. This second method uses a macro level of analysis. The authors developed both frameworks as part of a long term research program about the space activities of developing countries. This aspect of the research focuses on harnessing multiple techniques to summarize complex, multi-disciplinary information about global space activity.     

Strategies and determinants for successful space technology transfer

The following paper reports the results of a research work carried from 2008 on the topic of strategies and determinants of space technology Transfer (TT). In particular, the aim of this study is to present: 1. The policies and strategies the major space agencies adopt for TT, 2. The operational mechanisms and determinants involved in the transfer of space technologies to other industrial sectors. To this extent we have conducted in the last five years: six case studies of large space agencies, four TT case studies concerning the construction of scientific satellites, two case studies focused on space to earth TT programs undertaken by the Japanese aerospace agency, and two TT case studies examining Italian space companies.The comparative and comprehensive analyses of these studies indicate that the space agencies of the more industrialized countries aim primarily at consolidating and developing the industrial systems in their own countries, which include the use of technology transfer programs, and that the transfer of space technologies follows the route “Earth–Space–Earth”. With regard to the determinants of the TT process, the most important of these correlate with the type of technology in transfer, whereas organizational, economic and financial determinants have less significance.
