This would alter the initial assumptions of the satellite design (which was to be launched uncrewed to equatorial orbit at 1100 km altitude), and so would lead to a different optimum design. In particular the satellite would be assembled in a lower orbit, and would use solar-electric power to change its orbit after assembly. Potential advantages of the proposal are that crewed intervention in the deployment process could reduce the risk of failure of an entirely automatic deployment system, and such cooperation could widen political support for the project. It might also be an economically useful activity for NASA to plan for after the assembly of the International Space Station. Potential disadvantages of the proposal are that the project could become entangled in NASA's political struggle to survive as a monopoly space agency, and the cost would be likely to rise many times higher than the original cost target. In order to make progress towards deciding whether this is a good direction for the SPS team to aim in, there is a need for some work to be done to design a system for astronaut-assisted deployment in low orbit and subsequent orbit-raising. If the Japanese team wish him to do so, Dr Rogers has offered to promote the idea at the political level in the USA.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0200089000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"麻布大学"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Azabu University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"コリンズ, パトリック"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Collins, Patric Q.","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0200089.pdf","filesize":[{"value":"247.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0200089.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33316/files/SA0200089.pdf"},"version_id":"f12d8801-5072-4d7d-8b8a-1b2eaabc3c9b"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"日米協力でSPS2000を実現しようという提案について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日米協力でSPS2000を実現しようという提案について"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33316","relation_version_is_last":true,"title":["日米協力でSPS2000を実現しようという提案について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:10:21.322073+00:00"}
