But it is not easy to investigate them by using telescopes, because they are too small to be examined sufficiently. One way to solve this problem is to send a space probe. The more asteroids are examined, the more discoveries can be gotten. In this present study, orbital elements of the space probe were optimized to meet as many asteroids as possible in two cases. In one case, asteroids whose semi-major axes are close to 2.35 AU (1 AU equals 1.5 x 10(exp 8)) km were targeted (case 1). In the other case, all asteroids in the Main Belt were concluded in the calculation where the original function was introduced (case 2). What is more, a quantitative way to throw the space probe into a clockwise orbit was gotten.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047897037","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_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0918-8053","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"慶應義塾大学 大学院理工学研究科"},{"subitem_text_value":"東京都立科学技術大学 大学院工学研究科"},{"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":"Keio University Graduate School of Science and Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Metropolitan Institute of Technology Graduate 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":"栃本, 昌孝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本, 道弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川口, 淳一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tochimoto, Masataka","creatorNameLang":"en"}],"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":"メインベルト小惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"太陽系","subitem_subject_scheme":"Other"},{"subitem_subject":"火星","subitem_subject_scheme":"Other"},{"subitem_subject":"木星","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙プローブ","subitem_subject_scheme":"Other"},{"subitem_subject":"望遠鏡","subitem_subject_scheme":"Other"},{"subitem_subject":"シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"重力定数","subitem_subject_scheme":"Other"},{"subitem_subject":"Main-belt asteroid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solar system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mars","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Jupiter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"space probe","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"telescope","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitational constant","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":"Estimation of the number of asteroids in the Main belt for a space probe with a clockwise orbit to approach","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of the number of asteroids in the Main belt for a space probe with a clockwise orbit to approach","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1559","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7670","relation_version_is_last":true,"title":["Estimation of the number of asteroids in the Main belt for a space probe with a clockwise orbit to approach"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:35:53.880148+00:00"}
