如果提交给日本空间活动委员会的计划被采纳,则日本的空间活动预算将增加两倍。一项从1989年开始的15年计划需要6万亿日元,与之相比,同一时期美国和欧洲用于空间活动的经费预计分别为4万亿日元和1万3千亿日元。但是,目前日本的空间活动规模并不很大,其年预算为1300亿日元(合10亿美元)。日本雄心勃勃的新的空间投资计划的中心是在2010年之前建立一个低地轨道上的空间站。该空间站包括实验舱、一个载人共轨平台(co-orbiting platform)以及一个将平台拖 If the plan submitted to the Japan Space Activities Committee is adopted, Japan's space activities budget will tripled. A 15-year plan, starting in 1989, required 6 trillion yen, compared with 4 trillion yen and 1.30 trillion yen respectively for space activities in the United States and Europe during the same period. However, at present Japan's space activities are not large in scale with an annual budget of 130 billion yen (about 1 billion U.S. dollars). The centerpiece of Japan's ambitious new space investment plan is to establish a space station on low earth orbit by 2010. The space station includes a laboratory module, a co-orbiting platform, and a platform to tow
