dos2とは 意味・読み方・使い方

DOS-2 designation given to a space station, launched as part of the Salyut programme, which was lost in a launch failure on 29 July 1972, when the failure of the second stage of its Proton-K launch vehicle prevented the station from achieving orbit, it instead fell into the Pacific Ocean. The station, which would have been given the designation Salyut 2 had it reached orbit, was structurally identical to Salyut 1, as it had been assembled as a backup unit for that station. Four teams of cosmonauts were formed to crew the station, of which two would have flown:

• Alexey Leonov and Valeri Kubasov
• Vasily Lazarev and Oleg Makarov
• Aleksei Gubarev and Georgi Grechko
• Pyotr Klimuk and Vitaly Sevastyanov
