If the risk is not acceptable, a debris shield is added to the component. An aluminum alloy plate has high reliability since it has been used as a shield of the ISS. For an unmanned spacecraft, however, the effect on the total weight is not ignorable. A lot of light-weight bumpers have been developed before now. Almost all new bumpers have not finished assessments of protective abilities against space environment. This study investigated shielding effects of MLI blankets. The MLI blanket captured projectiles of 0.lmm in diameter when its areal density was increased by using thick reflectors. If an outer film was covered with ITO (Indium-Tin Oxide), the projectile fractured more. An outer film is considered to influence with fragmentation of debris. Moreover, embossed reflector films seemed to improve shielding effects of a MLI blanket.","subitem_description_type":"Other"}]},"item_4_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_4_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_4_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1630052027","subitem_description_type":"Other"}]},"item_4_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-16-011","subitem_description_type":"Other"}]},"item_4_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_4_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_4_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"東出, 真澄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平井, 隆之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒崎, 裕久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長谷川, 直"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本, 晴久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Higashide, Masumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirai, Takayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurosaki, Hirohisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hasegawa, Sunao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsumoto, Haruhisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1630052027.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1630052027.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3335/files/AA1630052027.pdf"},"version_id":"4967e87b-4202-426b-9bb1-7c4030fad395"}]},"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 object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Shielding effect of MLI against submillimeter debris","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Shielding effect of MLI against submillimeter debris","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["821","1503","1829","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-08"},"publish_date":"2017-05-08","publish_status":"0","recid":"3335","relation_version_is_last":true,"title":["Shielding effect of MLI against submillimeter debris"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:04:44.751726+00:00"}
