Report Number: R16E0121 Responsible Representative: Jun Gomi(Human Spaceflight Technology Directorate) Contact Information: Keiichiro Fujimoto(fujimoto.keiichiro@jaxa.jp) Members: Takayuki Ito, Keiichiro Fujimoto, Tetsufumi Ohmaru Subject Category: Space(Rocket,Space transportation) Abstract Evaluation of the heat flux induced by the RCS jet and free-stream interaction is conducted. For each RCS thrustors, wide range of heat flux CFD analysis is conducted. Goal By employing multi-disciplinary coupling analysis based on the high-fidelity numerical simulations, new quantitative safety analysis method is under the development. Objective of this study is・・・<<read more>>
Report Number: R16E0119 Responsible Representative: Shinichiro Sakai(Institute of Space and Astronautical Science Department of Spacecraft Engineering ) Contact Information: Miki Nishimoto(nishimoto.miki@jaxa.jp) Members: Hideyo Negishi, Yu Daimon, Hiroaki Amakawa, Kei Nishimura, Mayu Matsumoto, Hironori Fujiwara, Miki Nishimoto Subject Category: Space(Rocket) Abstract By acquiring the technique of pinpoint landing to the place where you want to land and demonstrating it on the moon, it enables landing the planet that is more restrictive than the moon and sample return. Goal It is the・・・<<read more>>
Report Number: R16E0118 Responsible Representative: Hironori Maejima(Research and Development Directorate, Research Unit I) Contact Information: Kazuhiko Yamada(yamada.kazuhiko@jaxa.jp) Members: Kazuhiko Yamada, Yusuke Higo Subject Category: Space(Moon Planet,Spacecraft,Space engineering,Space science) Abstract Hayabusa' is the first sample return mission from an asteroid in deep space and proved its value worldwide. The sample return mission will become one of important missions in future planetary exploration. A sample return capsule is indispensable technology to realize it. The objectives of this activity are to take over・・・<<read more>>
Report Number: R16E0117 Responsible Representative: Masaki Fujimoto(Institute of Space and Astronautical Science, Department of Solar System Sciences) Contact Information: Toshifumi Shimizu(shimizu.toshifumi@jaxa.jp) Members: Yusuke Kawabata, Yumi Bamba, Toshifumi Shimizu, Takahiro Hasegawa, Takafumi Doi Subject Category: Space(Space science) Abstract Our study focuses on understanding of the mechanism responsible for the occurrence of the solar flares. We derive 3D magnetic field structure in the corona by performing a 3D magnetohydrodynamics simulation using vector magnetic field map acquired with the Hinode spacecraft. We investigate・・・<<read more>>
Report Number: R16E0116 Responsible Representative: Masaki Fujimoto(Institute of Space and Astronautical Science, Department of Solar System Sciences) Contact Information: Masaki Fujimoto(fujimoto.masaki@jaxa.jp) Members: Masaki Fujimoto, Kenya Shimizu Subject Category: Space(Space science,Space philosophy) Abstract Magnetic reconnection, a process that explosively releases magnetic energy, is considered to be triggered when two oppositely directed field lines are strongly pushed against each other so that the distance between the two field lines become small. How small the distance has to be for magnetic reconnection to・・・<<read more>>
