In order to transport the balloon at the appropriate altitude, a small capsule and its direct entry to the Venusian atmosphere has been proposed here. The high-speed entry to the Venusian atmosphere at about 11.5 km/s exerts severe aerodynamic heating on the capsule. The release of the balloon with 50 cm in diameter by 20 m long requires lots on the release scenario and the aerodynamic mechanisms. The entry flight and the release of the long balloon at the altitude of 45 km is focused on and described in this paper.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0045497031","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Institute of Space and Astronautical Science (ISAS)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0918-8053","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"アイ・エイチ・アイ・エアロスペース"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"IHI Aerospace Co.
