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 time it was uncrewed, which meant that the crew of Soyuz T-13 had to perform a manual docking and do repairs to the station.
Rakesh Sharma, aboard Salyut 7 for 7 days, 21 hours, and 40 minutes, conducted an Earth observation program concentrating on India. He also did life sciences and materials processing experiments, including silicium fusing tests. He is also reported to have experimented with practicing yoga to deal with the effects of prolonged orbital spaceflight.[1]
The Soyuz T-11 launch crew Malyshev, Strekalov, and Sharma returned from space in the Soyuz T-10 spacecraft on 11 April 1984.
