DOS-2

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:
Whilst Salyut 1 has been visited by two three-man 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 been manned by two crews of two. Following the loss of the station, the crews were transferred to the DOS-3 programme.
Space station
A space station is a spacecraft capable of supporting a crew which is designed to remain in space for an extended period of time, and to which other spacecraft can dock. A space station is distinguished from other spacecraft used for human spaceflight by its lack of major propulsion or landing...

Proton-K
The Proton-K, also designated Proton 8K82K after its GRAU index, 8K82K, is a Russian, previously Soviet, carrier rocket derived from the earlier Proton. It was built by Khrunichev, and is launched from sites 81 and 200 at the Baikonur Cosmodrome in Kazakhstan...

Salyut 1
Salyut 1 was the first space station of any kind, launched by the USSR on April 19, 1971. It was launched unmanned using a Proton-K rocket. Its first crew came later in Soyuz 10, but was unable to dock completely; its second crew launched in Soyuz 11 and remained on board for 23 days...
