Debris over 10 cm already reached to 20 thousand. It is estimated that 1 cm debris has exceeded half a million. If the space debris continues to increase as it is, it is difficult for all parties to stably perform space activities. There are also concerns about acts of destroying satellites intentionally, and acts of obstructing satellites in orbits. While the number of countries, companies and individuals who wish to utilize outer space are also increasing, space debris and satellite destruction / disturbance activities are not related to some specific state parties, but related to any stakeholders interested in space activities. In this presentation activities to detect space debris and intentional destruction / disturbing activities to avoid such troubles (space situation awareness: SSA) are considered. This presentation will try to show that SSA activities have common benefit for all related parties, and also have a character as an international common good.","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: AA1830034019","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-18-011","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_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"防衛省防衛研究所"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"The National Institute for Defense Studies, Ministry of Defence, Japan"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"橋本, 靖明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hashimoto, Yasuaki","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":"AA1830034019.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830034019.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2823/files/AA1830034019.pdf"},"version_id":"59ae365f-2427-4ec0-83bb-bcf2d135357f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"宇宙状況認識とその意味","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"宇宙状況認識とその意味"}]},"item_type_id":"4","owner":"1","path":["795","1502","1828","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-15"},"publish_date":"2019-03-15","publish_status":"0","recid":"2823","relation_version_is_last":true,"title":["宇宙状況認識とその意味"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:15:31.876599+00:00"}
