Report Number: R16E0080 Responsible Representative: Koji Yamanaka(Research and Development Directorate, Research Unit I) Contact Information: Aki Goto(goto.aki@jaxa.jp) Members: Aki Goto, Kazunori Shimazaki Subject Category: Space(Space utilization) Abstract Our goal is to obtain the technology and knowledge to protect spacecraft and astronauts from harsh space environment for expanding future space activities. Long-term-stay under safer environment is especially required in the future manned-mission. We, therefore, address the radiation shielding technology in terms of materials forsupporting the safe and long-period manned space activity.・・・<<read more>>
Report Number: R16E0079 Responsible Representative: Koichi Okita(Research and Development Directorate, Unit IV) Contact Information: Masatoshi Kodera(kodera.masatoshi@jaxa.jp) Members: Masahiro Takahashi, Masatoshi Kodera, Shuichi Ueda, Masaaki Fukui, Toshihiko Munakata, Masaharu Takahashi Subject Category: Space(Space transportation) Abstract In order to reduce the cost of space transportation systems significantly, reusable rockets are considered. However, in order to extend the structural lifetime, it is necessary to operate with relatively low engine power, leading to a decrease in launch capability. Therefore, a combined cycle of a・・・<<read more>>
