The focus was made on the removal of respectively ENVISAT satellite, ADEOS 2 satellite, and 18 pieces of SL-16 rocket upper stage from the initial population of year 2009, and the results were compared to the Baseline (scenario without removal). The analysis let underline noticeable differences between the scenarios: removing ENVISAT or ADEOS 2 reveals not to have significant impact on the future population; butremoving 18 pieces of SL-16 rocket conducts to a decrease of the debris population at same epoch, which demonstrates the importance of the number of objects to be removed in order to strengthen the impact of a remediation activity. The altitude of removed objects also appeared as a significant criterion. In addition, aprogram has been implemented in order to track the origins at initial year of all fragments present in a given year in order to determine the most impactful objects in terms of debris generation. This process lets expect to better understand the conditions for an effective removal procedure","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: AA1530025010","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-14-013","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(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_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_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"九州大学"},{"subitem_text_value":"九州大学"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"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":"ゼムラ, メリッサ"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"花田, 俊也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河本, 聡美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zemoura, Melissa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hanada, Toshiya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawamoto, Satomi","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":"AA1530025010.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1530025010.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3740/files/AA1530025010.pdf"},"version_id":"b7f96923-0c3e-493a-a2e0-8dc5ec7a963c"}]},"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":"Evaluation of the impacts of near-Earth-orbit debris removal & track of impactful events' origins","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation of the impacts of near-Earth-orbit debris removal & track of impactful events' origins","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["856","1504","1830","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-18"},"publish_date":"2015-05-18","publish_status":"0","recid":"3740","relation_version_is_last":true,"title":["Evaluation of the impacts of near-Earth-orbit debris removal & track of impactful events' origins"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:55:55.538324+00:00"}
