The ion engines onboard ETS-8 and Hayabusa explorer open the era of electric propulsion. Especially the microwave discharge ion engines mu-10 achieved 26,000-hour space operation and succeeded to rendezvous with an asteroid. These technologies will be expanded to the Deep Space Transportation System and various kinds of satellites. In order to realize such a vast expansion of the ion engines in space the numerical analysis on lifetime of the electro-static grid system, that is JIEDI (JAXA Ion Engine Development Initiatives) tool, has a top priority to develop. This paper reports the development scheme, proposed schedule and application scenario., JAXA Special Publication, 宇宙航空研究開発機構特別資料
