I-site Namba, Osaka Prefecture University), Osaka, Japan, We had observed rapid increase of spacecraft contamination on HAYABUSA spacecraft at the time when lack of neutralization on its ion thrusters had occurred. It is considered that spacecraft charging at that time had attracted the charged particles and had enhanced the surface contamination. A numerical code for charging analysis has been developing to estimate the return currents as a function of the spacecraft potential in ion thruster operation for HAYABUSA. The estimation will clarify the contributions of charged and neutral particles to the contamination data obtained by the spacecraft. In this paper, we introduce the present status of the development of the code and preliminary charging analysis for HAYABUSA with ion beam emission by using the code., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530019022, レポート番号: JAXA-SP-14-012}, pages = {149--153}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {小惑星探査機はやぶさにおけるイオンエンジン中和不良時の宇宙機帯電解析}, volume = {JAXA-SP-14-012}, year = {2015} }
