The crew comprising ship's commander V A Dzhanibekov, flight engineer S E Savitskaya and cosmonaut-research I P Volk, docked to the Salyut-7 orbital station to conduct scientific and technical studies and experiments.

Narrative (adapted from D S F Portree's Mir Hardware Heritage, NASA RP-1357, 1995)

The crew included veteran cosmonaut Vladimir Dzhanibekov, Buran shuttle program cosmonaut Igor Volk, and Svetlana Savitskaya. On July 25 Dzhanibekov and Savitskaya performed a 3 hr, 30 min EVA, during which they tested the URI multipurpose tool. They cut, welded, soldered, and coated metal samples. During the Pamirs' stay, the six cosmonauts aboard Salyut 7 also conducted Rezonans tests and collected station air samples.

AKA: Pamir (Pamir mountains); Soyuz T-12.

  • Salyut 7 Due to cancellation of the Almaz military station, and delays in the Mir project, the decision was taken in the late 1970's to fly the back-up to DOS-5 / Salyut 6. This was launched as Salyut 7 in 1982. The opportunity was still taken to fly 'guest cosmonauts' from friendly countries on short visits to the stations, although emphasis was placed on military experiments. Salyut 7 was able to conduct significant military experiments thanks to the greatly increased volume and payload of the TKS modules diverted from the Almaz programme that docked with the station.
