The field of space activity has now been expanded even to the rim of the outer solar system. In this context, the Japan Aerospace Exploration Agency (JAXA) has started investigating a Deep Space Port built at the L2 Lagrange point in the Sun-Earth system. For the purpose of making the deep space port practically useful, there is a need to establish a method to making spaceship depart and return from/to the port. This paper first discusses the escape maneuvers originating from the L2 point under the restricted three-body problem. Impulsive maneuvers from the L2 point are extensively studied here, and using the results, optimal low-thrust escape strategies are synthesized. The paper presents, as the major results, the optimal escape and acceleration maneuvers schemes using Electric Delta-V Earth Gravity Assist (EDVEGA) technique, in which the comprehensive delta-V evaluation method is presented. The results obtained are highly useful, ushering the future solar system exploration era.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063480007","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学 大学院工学系研究科"},{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo School of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Space and Astronautical Science"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松本, 道弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川口, 淳一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsumoto, Michihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawaguchi, Junichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ラグランジュ平衡点","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙機軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"L2点","subitem_subject_scheme":"Other"},{"subitem_subject":"脱出軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"数学的解析","subitem_subject_scheme":"Other"},{"subitem_subject":"運動方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"3体問題","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道最適化","subitem_subject_scheme":"Other"},{"subitem_subject":"低推力推進","subitem_subject_scheme":"Other"},{"subitem_subject":"地球重力","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星間遷移軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"最適化","subitem_subject_scheme":"Other"},{"subitem_subject":"DCNLP","subitem_subject_scheme":"Other"},{"subitem_subject":"EDVEGA","subitem_subject_scheme":"Other"},{"subitem_subject":"Lagrangian equilibrium point","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spacecraft trajectory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"L2 point","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"escape trajectory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mathematical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equation of motion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"three body problem","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"trajectory optimization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"low thrust propulsion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Earth gravitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"interplanetary transfer orbit","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"optimization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"DCNLP","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"EDVEGA","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Escape trajectory from the Sun-Earth L2 point","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Escape trajectory from the Sun-Earth L2 point","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1558","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7572","relation_version_is_last":true,"title":["Escape trajectory from the Sun-Earth L2 point"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:37:26.602219+00:00"}
