Rakesh Sharma, Yury Malyshev and Gennadi Strekalov. Soyuz programme (Crewed missions)

Soyuz T-11 was the 6th expedition to Salyut 7, and carried the first Indian cosmonaut to the Salyut 7 station.

Salyut 7 was uncrewed after the undocking of Soyuz T-11 in October 1984 until Soyuz T-13 docked with the station in June 1985. Salyut 7 developed problems during the uncrewed time, which meant that the crew of Soyuz T-13 had to perform a manual docking and do repairs to the station.
