Salyut 7 (Russian: Салют-7; English: Salute 7) (a.k.a. DOS-6, short for Durable Orbital Station[1]) was a space station in low Earth orbit from April 1982 to February 1991.[1] It was first crewed in May 1982 with two crew via Soyuz T-5, and last visited in June 1986, by Soyuz T-15.[1] Various crew and modules were used over its lifetime, including 12 crewed and 15 uncrewed launches in total.[1] Supporting spacecraft included the Soyuz T, Progress, and TKS spacecraft.[1]
It was part of the Soviet Salyut programme, and launched on 19 April 1982 on a Proton 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.
