Institute of Space and Astronautical Science (ISAS), Japan Aerospace Exploration Agency (JAXA)), Sagamihara, Kanagawa Japan, Enormous research and development efforts have been devoted to the electric propulsion, which aims higher exhaust velocity and higher specific impulse than the chemical propulsion. As the results the microwave discharge ion engines made the Hayabusa spacecraft rendezvous with the asteroid. In the contrast to high specific impulse, there is another policy to promote inert propellant, such as solid and powder, without warming power and propellant charging procedure. They will contribute to thrusters on the sounding probes ejected from a mother ship in deep space. This paper outlines R&D status on the microwave discharge Hall thruster, the microwave discharge ion engines and the power thruster as up-dated topics in ISAS/JAXA., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064958010, レポート番号: JAXA-SP-06-016}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {電気推進の研究・開発・宇宙利用の方向性について}, volume = {JAXA-SP-06-016}, year = {2007} }
