Salyut 7 (Russian: Салют-7, lit. 'Salute 7'), also known as DOS-6 (Durable Orbital Station 6) was a space station in low Earth orbit from April 1982 to February 1991. It was first crewed in May 1982 with two crew via Soyuz T-5, and last visited in June 1986, by Soyuz T-15. Various crew and modules were used over its lifetime, including 12 crewed and 15 uncrewed launches in total. Supporting spacecraft included the Soyuz T, Progress, and TKS spacecraft.
It was part of the Soviet Salyut programme, and launched on 19 April 1982 on a Proton-K rocket from Site 200/40 at the Baikonur Cosmodrome in the Soviet Union. Salyut 7 was part of the transition from monolithic to modular space stations, acting as a testbed for docking of additional modules and expanded station operations. It was the eighth space station of any kind launched. Salyut 7 was the last of both the second generation of DOS-series space stations and of the monolithic Salyut Program overall, to be replaced by Mir, the modular, expandable, third generation.
