Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)), Sagamihara, Kanagawa Japan, Recent Space Exploration sometimes assume an apparent gravity capture around the Moon, using the solar tidal force effect accumulated while flying in the far boundary region of the Earth gravity field. One of the such trajectories we may plan is that S/C which departs from LEO changes the orbit by lunar swing-by and then re-approaches the moon. In this case whether S/C will be captured by the moon or not, however, depends on when S/C departs from LLO, when it swings by the moon and how it approaches the moon. Therefore, such spontaneous capture is hardly applicable to the flexible and practical transportation systems to the moon. This paper focuses on the trajectory from lunar swing-by to the re-approach the moon, and presents how the lunar swing-by conditions is relaxed taking the advantage of the artificial acceleration, electric propulsion means., 資料番号: AA0064733024}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {低DeltaVでの地球月遷移軌道計画と電気推進を用いた出発ウインドウの拡大について}, volume = {2008}, year = {2009} }
