These points are also thought as a gateway for the interplanetary transfer in the near future. This paper investigates the escape trajectories from the Earth's gravity leaving the Sun-Earth L2 point in the restricted three-body problem. Firstly, we discussed the one-impulse escape strategy assuming velocity correction only at L2 point, and the two-impulse escape strategy assuming the first velocity correction at L2 point and the second velocity correction at the subsequent perigee point. By keeping the hyperbolic excess velocity constant, the required total velocity correction amount and the flight path geometry are analyzed both analytically using Jacobi integral. Finally, optimal escape trajectories of these strategies are calculated by SQP (Sequential Quadratic Programming method), optimal multi-impulse escape strategy is also investigated.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063481008","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":"総合研究大学院大学"},{"subitem_text_value":"宇宙航空研究開発機構"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Graduate University for Advanced Studies"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency"}]},"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":"中宮, 賢樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山川, 宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamiya, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamakawa, Hiroshi","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":"L2点","subitem_subject_scheme":"Other"},{"subitem_subject":"脱出軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"脱出速度","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道計算","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道力学","subitem_subject_scheme":"Other"},{"subitem_subject":"運動方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"逐次2次計画法","subitem_subject_scheme":"Other"},{"subitem_subject":"SQP法","subitem_subject_scheme":"Other"},{"subitem_subject":"地球重力","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道変換","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙機軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"速度","subitem_subject_scheme":"Other"},{"subitem_subject":"3体問題","subitem_subject_scheme":"Other"},{"subitem_subject":"Lagrangian equilibrium point","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":"escape velocity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orbit calculation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orbital mechanics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equation of motion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sequential quadratic programming method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"SQP method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Earth gravitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orbital maneuver","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spacecraft trajectory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"velocity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"three body problem","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":"Earth escape trajectories starting from L2 point","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Earth escape trajectories starting from L2 point","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1557","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7509","relation_version_is_last":true,"title":["Earth escape trajectories starting from L2 point"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:38:25.401331+00:00"}
