In the mid-1980s, Japan decided not only to invest in a totally domestic rocket, “H-II,” to acquire its independent access to space, but also to participate in the U.S. Space Station program to promote international space cooperation. Not until then did Japan try to achieve simultaneously both autonomy and international cooperation. This paper reexamines how Japan achieved a balance between autonomy and international cooperation in its space activities during the 1980s, from the perspective of Japan–U.S. diplomatic history. Against the background of the Japan–U.S. relations of those days, the similarities and differences between the two big space programs made it possible for Japan to decide them at the same time of the mid-1980s. 相似文献

An overview of a sounding rocket, S-520-25th, project on space tether technology experiment is presented. The project is prepared by an international research group consisting of Japanese, European, American, and Australian researchers. The sounding rocket will be assembled by the ISAS/JAXA and will be launched in the summer of 2009. The sounding rocket mission includes two engineering experiments and two scientific experiments. These experiments consist of the deployment of bare electrodynamic tape tether in space, a quick ignition test of hollow cathode system in space, the demonstration of bare electrodynamic tether system in space, and the test of the OML (orbital-motion-limit) current collection theory. 相似文献
