This time, the objective was driven by the question: \"How to maximize the relevance of a rendezvous mission to a given NEA by visiting the largest set of intermediate asteroids?\" For the competition, the spacecraft had to be launched from Earth with a hyperbolic excess velocity of up to 4 km/s. Then, using electric propulsion, the spacecraft had to flyby a maximum number of asteroids from a given list and rendezvous with a last one within 10 years. The mission was constrained to have a launch window between 2015 and 2025, and the spacecraft wet mass was assumed to be 1000 kg, with a spacecraft specific impulse of 3000 s and a thrust level constrained to 0.135 N. Finally, each asteroid could only be visited once. The performance index to be maximized was the number of asteroids and the final mass of the spacecraft. In this paper, we go over the methods used, results obtained and lessons learned.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064734032","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)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11567475","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"宇宙航空研究開発機構月・惑星探査プログラムグループ"},{"subitem_text_value":"宇宙航空研究開発機構月惑星探査推進グループ"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"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":"Delft University of Technology"},{"subitem_text_language":"en","subitem_text_value":"Delft University of Technology"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"JAXA Space Exploration Center, Japan Aerospace Exploration Agency (JAXA)(JASEC)"},{"subitem_text_language":"en","subitem_text_value":"JAXA Space Exploration Center, Japan Aerospace Exploration Agency (JAXA)(JSPEC)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"}]},"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":"山口, 智宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中宮, 賢樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"尾川, 順子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平林, 正稔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三桝, 裕也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oldenhuis, Rody P.S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Boere, Mirjam","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Tomohiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamiya, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Bellerose, Julie","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ogawa, Naoko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirabayashi, Masatoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mimasu, Yuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"CHOPIN: Methods and Results of the Fourth Global Trajectory Optimization Competition","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CHOPIN: Methods and Results of the Fourth Global Trajectory Optimization Competition","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1554","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7337","relation_version_is_last":true,"title":["CHOPIN: Methods and Results of the Fourth Global Trajectory Optimization Competition"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:41:05.338807+00:00"}
