 Planned orbital configuration of DOS-2 | |
DOS-2 was a space station, launched as part of the Salyut programme.
It 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.[3][4] 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.[1] Four teams of cosmonauts were formed to crew the station, of which two would have flown:[1]
- Alexei Leonov and Valeri Kubasov
- Vasily Lazarev and Oleg Makarov
- Aleksei Gubarev and Georgi Grechko
- Pyotr Klimuk and Vitaly Sevastyanov
Whilst Salyut 1 had been attempted to be visited by two three-person crews (Soyuz 10 and Soyuz 11), following modifications to the Soyuz 7KT-OK spacecraft (resulting in the new model Soyuz 7K-T) following the deaths of the crew of Soyuz 11, the spacecraft could only carry two cosmonauts, thus DOS-2 would have had two crews of two. Following the loss of the station, the crews were transferred to the DOS-3 programme.[1]
