三十多年来,日本从一个没有卫星发射能力的国家迅速成长为一支新兴的太空力量。日本宇宙开发事业团(NASDA)已经成功发射了30枚运载火箭和一系列卫星,他们正在努力拓展大型的H-2运载火箭,以期待在国际卫星发射市场上占据一席之地。早在1992年,日本宇宙开发事业团就曾帮助日本宇航员毛利卫搭乘美国航天飞机,实现了日本人的第一次太空飞行。日本宇宙开发事业团还参与了国际空间站的建造,负责研制一个日本实验舱(JEM)。日本航天活动的另一个重要角色——宇宙科学研究所(ISAS)则成功开发了一系列小型固体运载火箭。宇宙科学研究所的年度预算为20亿～25亿美元,其严谨的航天科研计划为日本在国际上赢得了良好的声誉。然而在2004年,日本航天计划却遭遇
For more than three decades Japan has rapidly grown from a country without satellite launch capability to a new space force. Japan’s Space Development Agency (NASDA) has successfully launched 30 launch vehicles and a series of satellites, and they are working hard to expand the large H-2 launch vehicle to look forward to gaining a place in the international satellite launch market. As early as 1992, the Japan Space Development Agency had helped Japanese astronaut Maori Wei take the US space shuttle to achieve the first Japanese space flight. JAXA also participated in the construction of the International Space Station and was responsible for the development of a Japanese laboratory module (JEM). Another important role for Japan’s space activities, the Institute of Astronautics (ISAS), has successfully developed a series of small solid-propellant vehicles. The annual budget of the Institute of Astronautics is between 2 billion and 2.5 billion U.S. dollars. Its rigorous space science and research program has earned Japan a good reputation internationally. However, in 2004, Japan’s space program suffered
