Snow and ice projectiles were launched into the snow target sintered at - 10 C for 15 minutes and at - 7 C for 45 minutes. The projectile and target porosity were about 32 and 36 percent respectively. The crater morphology depends on the projectile type and the degree of sintering of the target. The typical crater shape made by snow projectile is bowl shape with the depth to diameter ratio of about 0.5. The power law index of the impact velocity in the relationship between the projectile kinetic energy and the crater volume is about 1.5, which is rather smaller than 2.4 theoretically proposed by the scaling law in the strength regime.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047898007","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":"北海道大学低温科学研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido University"}]},"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":"荒川, 政彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arakawa, Masahiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"雪標的","subitem_subject_scheme":"Other"},{"subitem_subject":"クレーター","subitem_subject_scheme":"Other"},{"subitem_subject":"彗星","subitem_subject_scheme":"Other"},{"subitem_subject":"実験","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃速度","subitem_subject_scheme":"Other"},{"subitem_subject":"形態学","subitem_subject_scheme":"Other"},{"subitem_subject":"運動エネルギー","subitem_subject_scheme":"Other"},{"subitem_subject":"スケーリング法則","subitem_subject_scheme":"Other"},{"subitem_subject":"snow target","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"crater","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"comet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"experimentation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"impact velocity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"morphology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"kinetic energy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"scaling law","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":"Impact crater formed on sintered snow: Implication for the crater on comets","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Impact crater formed on sintered snow: Implication for the crater on comets","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1792","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20585","relation_version_is_last":true,"title":["Impact crater formed on sintered snow: Implication for the crater on comets"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:48:11.423814+00:00"}
