Message from the Director General September 2017 Saku Tsuneta Director General
Message from the Director General September 2017 Saku Tsuneta Director General Institute of Space and Astronautical Science Japan Aerospace Exploration Agency On April 28, 2016, the Japan former ISAS project managers, and levels, the satellite was declared to Aerospace Exploration Agency an Action Plan for Reforming ISAS have entered into its scheduled orbit (JAXA) made the difficult decision Based on the Anomaly Experienced in March 2017. The successful start to terminate attempts to restore by Hitomi was developed. In of the ARASE mission is a testament communication with the X-ray addition, “town hall meetings” were to the dedication and skills across Astronomy Satellite ASTRO-H (also held to share the spirit and practice JAXA. known as HITOMI), which was of the action plan with all ISAS ISAS is currently operating six launched on February 17, 2016, due employees. The plan, which was satellites and space probes: ARASE, to the communication anomalies applied to launch preparations of Hayabusa2, HISAKI, AKATSUKI, that occurred on March 26, 2016. the geospace exploration satellite HINODE, and GEOTAIL. Asteroid Since that time, in consultation with ARASE, contributed to the successful Explorer Hayabusa2, which is experts inside as well as outside and stable operation of that satellite, currently on its planned trajectory JAXA, the Institute of Space and and will be applied to other projects towards the 162173 Ryugu asteroid Astronautical Science (ISAS) has such as the Smart Lander for under ion engine power, is equipped been making every possible effort Investigating Moon (SLIM). The plan- with new technologies for solar to determine what went wrong, and do-check-act (PDCA) cycle should system exploration such as long- what can be done to prevent this work to further refine both current distance communication using Ka- from happening again in the future. -

MIT Japan Program Working Paper 01.10 THE GLOBAL COMMERCIAL SPACE LAUNCH INDUSTRY: JAPAN IN COMPARATIVE PERSPECTIVE Saadia M. Pekkanen Assistant Professor Department of Political Science Middlebury College Middlebury, VT 05753 [email protected] I am grateful to Marco Caceres, Senior Analyst and Director of Space Studies, Teal Group Corporation; Mark Coleman, Chemical Propulsion Information Agency (CPIA), Johns Hopkins University; and Takashi Ishii, General Manager, Space Division, The Society of Japanese Aerospace Companies (SJAC), Tokyo, for providing basic information concerning launch vehicles. I also thank Richard Samuels and Robert Pekkanen for their encouragement and comments. Finally, I thank Kartik Raj for his excellent research assistance. Financial suppport for the Japan portion of this project was provided graciously through a Postdoctoral Fellowship at the Harvard Academy of International and Area Studies. MIT Japan Program Working Paper Series 01.10 Center for International Studies Massachusetts Institute of Technology Room E38-7th Floor Cambridge, MA 02139 Phone: 617-252-1483 Fax: 617-258-7432 Date of Publication: July 16, 2001 © MIT Japan Program Introduction Japan has been seriously attempting to break into the commercial space launch vehicles industry since at least the mid 1970s. Yet very little is known about this story, and about the politics and perceptions that are continuing to drive Japanese efforts despite many outright failures in the indigenization of the industry. This story, therefore, is important not just because of the widespread economic and technological merits of the space launch vehicles sector which are considerable. It is also important because it speaks directly to the ongoing debates about the Japanese developmental state and, contrary to the new wisdom in light of Japan's recession, the continuation of its high technology policy as a whole. -
