Japan Aerospace Exploration Agency (JAXA) launched its own first manned experiment facility in space called the KIBO (Japanese Experiment Module, JEM) in 2008 and 2009 and started operations as part of International Space Station (ISS). To accomplish this Operation, JAXA made its own ground facility in Tsukuba, Japan, called Space Station Integration and Promotion Center (SSIPC). Ground personnel at SSIPC called the JEM Flight Control Team (JFCT) operate the KIBO and have learnt many lessons during its operation. In this presentation, some topics are chosen and explained such as (1) crew/ground personnel interaction and (2) planning lessons learned for manned space activities.  相似文献

Japan and China, as two advanced spacefaring nations in Asia-Pacific region, are often referred to as rivals in space. China's successful manned space launch program in 2003 and ASAT test in 2007 were considered as turning points which potentially introduces a “space race in Asia”. This article argues that there are three defining arenas in a space race: competition for prestige or soft power, competition over military capability or hard power, and competition of international services or public goods. It analyzes the objectives, norms and logics of space policy in Japan and China, and argues that these two countries have quite different thinking over what to do in space, explaining that they are playing different games in the first two arenas. However, Japan and China are competing for leadership and influence over the region. APRSAF and APSCO, two similar regional space organizations, are the vehicles for this competition. It concludes that there is a space race only in the third arena as a competition for leadership in Asia.  相似文献

For the European manned space activities an EVA space suit system was being developed in the frame of the Hermes Space Vehicle Programme of the European Space Agency (ESA). The space suit was to serve the needs for all relevant extravehicular activities for the Hermes Columbus operations planned to begin in 2004. For the present Russian manned space programme the relevant EVAs are performed by the Orlan-DMA semi-rigid space suit. The origin of its development reaches back to the 1970s and has since been adapted to cover the needs for extravehicular activities on Salyut and MIR until today. The latest modification of the space suit, which guaranteed its completely self-contained operation, was made in 1988. However, Russian specialists considered it necessary to start developing an EVA space suit of a new generation, which would have improved performance and would cover the needs by the turn of the century and into the beginning of the next century. Potentially these two suit developments could have a lot in common based on similarities in present concepts. As future manned space activities become more and more an international effort, a safe and reliable interoperability of the different space suit systems is required. Based on the results of the Munich Minister Conference in 1991, the European Space Agency and the Russian Space Agency agreed to initiate a requirements analysis and conceptual design study to determine the feasibility of a joint space suit development, EVA 2000. The design philosophy for the EVA 2000 study was oriented on a space suit system design of: space suit commonality and interoperability; increased crew productivity and safety; increase in useful life and reduced maintainability; reduced development and production cost. The EVA 2000 feasibility study was performed in 1992, and with the positive conclusions for EVA 2000, this approach became the new joint European Russian EVA Suit 2000 Development Programme. This paper gives an overview of the results of the feasibility study and presents the joint requirements and the proposed design concept of a jointly developed European Russian space suit.  相似文献

After the Apollo Moon program, the international space station represents a further milestone of humankind in space, International follow-on programs like a manned return to the Moon and a first manned Mars Mission can be considered as the next logical step. More and more attention is also paid to the topic of future space tourism in Earth orbit, which is currently under investigation in the USA, Japan and Europe due to its multibillion dollar market potential and high acceptance in society. The wide variety of experience, gained within the space station program, should be used in order to achieve time and cost savings for future manned programs. Different strategies and roadmaps are investigated for space tourism and human missions to the Moon and Mars, based on a comprehensive systems analysis approach. By using DLR's software tool FAST (Fast Assessment of Space Technologies), different scenarios will be defined, optimised and finally evaluated with respect to mission architecture, required technologies, total costs and program duration. This includes trajectory analysis, spacecraft design on subsystem level, operations and life cycle cost analysis. For space tourism, an expected evolutionary roadmap will be described which is initiated by short suborbital tourism and ends with visionary designs like the Space Hotel Berlin and the Space Hotel Europe concept. Furthermore the potential space tourism market, its economic meaning as well as the expected range of the costs of a space ticket (e.g. $50,000 for a suborbital flight) will be analysed and quantified. For human missions to the Moon and Mars, an international 20 year program for the first decades of the next millennium is proposed, which requires about $2.5 Billion per year for a manned return to the Moon program and about $2.6 Billion per year for the first 3 manned Mars missions. This is about the annual budget, which is currently spend by the USA only for the operations of its Space Shuttle fleet which generally proofs the affordability of such ambitious programs after the build-up of the International Space Station, when corresponding budget might become again available.  相似文献

When the requisite technology exists, the US political process will inevitably include lunar surface activities as a major space objective. This article examines a manned lunar base in terms of three distinct functions: the scientific investigation of the Moon and its environment; development of the capability to use lunar resources for beneficial purposes throughout the Earth-Moon systems; and conduct of R&D leading to a self-sufficient and self-supporting manned lunar base. Three scenarios are outlined with respect to each possible function.  相似文献

During the next eight years the United States, European countries within the European Space Agency, Canada, and Japan will engage in the design and construction of facilities included in the current conceptual design of the U.S./International Space Station. The object will be to build a manned space facility capable of supporting scientific research, technological development, and commercial operations. This paper is directed towards an overview of the essential requirements for successful scientific use of the Space Station. Because specific supporting technologies will change so drastically before heavy use can begin, it is important to discuss the most fundamental aspects of user requirements; namely, (1) What are the characteristics of a remote, manned space facility that can promote first rate scientific use? (2) What does it take to achieve such a facility, and (3) What guidelines can be given such that once the facility is in operation it attracts the best possible scientific talent?  相似文献

This article reviews the current status of the Chinese space programme, covering its military origins, launchers, applications satellites, manned spaceflight and exploration. It examines the growing commercialization of China's space activities and how far this is likely to be successful, especially in the light of MTCR constraints and other legal regulations. It is nonetheless concluded that commercialization, along with joint ventures with foreign companies, has been crucial to the development of China's space programme. However, the country still lacks the resources to become a first-rank space power.  相似文献

This Viewpoint presents an industrial perspective of the policies needed to support and advance the capabilities and competitiveness of the European space industry. It is argued that Europe needs a coordinated longterm space policy to help create the climate in which industry can invest in and exploit space. Europe must also accelerate the development of advanced technology products and services, improve its competitiveness in applications and commercial markets including launchers, and secure fair and reliable international partnerships in in-orbit infrastructure and manned space activities. To this end European governments are urged to acknowledge the increasing political, economic and military importance of space and their continuing governance of space activities, and to establish mechanisms that promote industrial competitiveness; the development of the commercial sector; autonomy in key technologies; and international partnerships which are fair and affordable.  相似文献

Despite its straightened circumstances and doubts about how much political support it receives, Russia's space programme continues — and continues to plan for new activities and applications. This edited version of the National Paper of the Russian Federation, presented at Unispace III in July 1999, details some of the country's major achievements in space in recent years and sets out the main areas it intends to pursue for the early twentieth-first century. While emphasis is placed on communications, remote sensing, navigation and space science, the commitment to manned flight remains.  相似文献

In the past few years the UK has become increasingly active as the financial conscience of the European Space Agency. This is not because the UK government has a wish to spend more on its national space effort; it is because it remains unconvinced of the benefits of certain European space activities, notably manned endeavours. In the absence of an effective UK space lobby, the government's policies have remained largely unchallenged. This article traces the growth of the Parliamentary Space Committee in the context of developments in recent European space policy and highlights the need for an active UK space lobby.  相似文献
