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.

This is Soyuz's 68th flight, and 49th crewed flight.

The Soyuz is a Soviet crewed spaceship, developed to made crewed lunar missions. This version called 7K will fly 4 times on the giant launcher N1, and several tens of times on Proton to fly over the Moon, which will be successful during the mission Zond 4. Soyuz will become the first spacecraft to transport living beings to the Moon during the flight of Zond 5, with two turtles. Subsequently, it is adapted to low orbit and will fly on the Soyuz launcher to serve the Salyut and Mir stations and the ISS.
