Vladimir Aleksandrovich Dzhanibekov ((ロシア語:Владимир Александрович Джанибеков), born 13 May 1942) is a former cosmonaut who made five flights. == Biography == Dzhanibekov was born Vladimir Aleksandrovich Krysin ((ロシア語:Владимир Александрович Крысин)) in the remote area of in what was then Bostanliq District, South Kazakhstan Region, Kazakh SSR (since 1956 – Tashkent Region, Uzbekistan) on 13 May 1942. His family moved to Tashkent soon after his birth. In 1964 he married Liliya Munirovna Dzhanibekova, who was a descendant of Janibeg, medieval ruler of the Golden Horde. As her father had no sons, Dzhanibekov took his wife's family name in order to honour her ancestry and continue her line of descent, an unusual step for a husband in the Soviet Union. In 1960 he entered Leningrad University to study physics, where he became involved in flying, something that he had always been interested in. In 1961 he decided to enroll in the V. M. Komarov Higher Military Flying School at Yeisk and simultaneously studied at the Taganrog State University of Radioengineering. Four years later he graduated and became a flying instructor in the Soviet Air force serving at military training unit number 99735 in Taganrog in 1968–1970. In 1970 during the visit of Gherman Titov to the Taganrog-based training unit, he was selected into the team of cosmonauts.〔(Vladimir Dzhanibekov – Сайт школы №50 г.Ташкента ). school50.uz〕 This was the same year that he joined the Communist Party. Dzhanibekov made five flights: Soyuz 27, Soyuz 39, Soyuz T-6, Soyuz T-12 and Soyuz T-13. In all he had spent 145 days, 15 hours and 56 minutes in space over these five missions. He had also performed two EVAs with a total time of 8 hours and 35 minutes. In 1985 he demonstrated the tennis racket theorem, subsequently also called the ''Dzhanibekov effect'', by showing the that in free-fall rotation about an object's second principal axis is unstable. After leaving the cosmonaut program in 1986, he became involved in politics. He was the Deputy to the Supreme Soviet of Uzbek SSR from 1985 until 1990. He is also interested in photography and painting and his works, predominantly about space, are owned by museums and private collectors. He also became interested in ballooning, and flying around the world. He made only one flight though, which lasted only 30 minutes. He, Larry Newman and Don Moses lifted off in Earthwinds on 13 January 1993 but could not penetrate a strong inversion layer and tore the ballast balloon on a mountain peak. The minor planet 3170 Dzhanibekov, discovered by Soviet astronomer Nikolai Stepanovich Chernykh in 1979, is named after him. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vladimir Dzhanibekov」の詳細全文を読む スポンサード リンク
