To fully understand their nature and origin, we need further quantitative analysis. Here, we mapped and characterized in detail all rocks, above the resolution limit of the high-resolution images acquired during the Hayabusa mission. This included compiling information on ca.20,000 rock materials ranging from m-size boulders to cm-size pebbles, which cover the main body of Itokawa. Though the slope indices of the cumulative-size-frequency-distribution plots of the rock materials show a value of -3, approximately matching those of lunar craters, the value changes to -1 around 1-2 m. This trend is consistent with the putative impact origin of the boulders considering the scale effect in the strength regime of the boulders and geometric-saturation.","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"},{"subitem_description":"形態: CD-ROM1枚","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"},{"subitem_description":"Note: One CD-ROM","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064739025","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":"AA12268968","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学総合研究博物館"},{"subitem_text_value":"東京大学総合研究博物館"},{"subitem_text_value":"東京大学総合研究博物館"},{"subitem_text_value":"東京大学総合研究博物館"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Univerisity Museum, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Univerisity Museum, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Univerisity Museum, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Univerisity Museum, University of Tokyo"}]},"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":"丸山, 智志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮本, 英昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山口, 優夢"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maruyama, Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyamoto, Hideaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeuchi, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Yuumu","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":"A Statistical Study on the Putative Impact Origin of Boulders Covering S-type Asteroids","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Statistical Study on the Putative Impact Origin of Boulders Covering S-type Asteroids","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1787","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20369","relation_version_is_last":true,"title":["A Statistical Study on the Putative Impact Origin of Boulders Covering S-type Asteroids"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:51:13.246627+00:00"}
