The Salyut programme was the first space station programme, undertaken by the Soviet Union. It involved a series of four crewed scientific research space stations and two crewed military reconnaissance space stations over a period of 15 years, from 1971 to 1986. Two other Salyut launches failed. In one respect, Salyut had the task of carrying out long-term research into the problems of living in space and a variety of astronomical, biological and Earth-resources experiments, and on the other hand the USSR used this civilian programme as a cover for the highly secretive military Almaz stations, which flew under the Salyut designation. Salyut 1, the first station in the programme, became the world's first crewed space station.
Soyuz 18 was a 1975 Soviet crewed mission to Salyut 4, the second and final crew to man the space station. Pyotr Klimuk and Vitaly Sevastyanov set a new Soviet space endurance record of 63 days and the mark for most people in space simultaneously (seven) was tied during the mission.
Salyut 6, DOS-5, was a Soviet orbital space station, the eighth station of the Salyut programme. It was launched on 29 September 1977 by a Proton rocket. Salyut 6 was the first space station to receive large numbers of crewed and uncrewed spacecraft for human habitation, crew transfer, international participation and resupply, establishing precedents for station life and operations which were enhanced on Mir and the International Space Station.
Salyut 7 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.
Soyuz 29 was a 1978 crewed Soviet space mission to the Salyut 6 space station. It was the fifth mission, the fourth successful docking, and the second long-duration crew for the orbiting station. Commander Vladimir Kovalyonok and flight engineer Aleksandr Ivanchenkov established a new space-endurance record of 139 days.
Soyuz 16 was a December, 1974, crewed test flight for a joint Soviet-United States space flight which culminated in the Apollo–Soyuz mission in July 1975. The two-man Soviet crew, Anatoly Filipchenko and Nikolai Rukavishnikov, tested a docking ring and other systems to be used in the joint flight.
Soyuz 28 was a March 1978 Soviet crewed mission to the orbiting Salyut 6 space station. It was the fourth mission to the station, the third successful docking, and the second visit to the resident crew launched in Soyuz 26.
Soyuz 32 was a 1979 Soviet crewed space flight to the Salyut 6 space station. It was the eighth mission to and seventh successful docking at the orbiting facility. The Soyuz 32 crew was the third long-duration crew to man the space station.
Soyuz 34 was a 1979 Soviet uncrewed space flight to the Salyut 6 space station. It was sent to supply the resident crew a reliable return vehicle after the previous flight, Soyuz 33, suffered an engine failure.
Soyuz 35 was a 1980 Soviet crewed space flight to the Salyut 6 space station. It was the 10th mission to and eighth successful docking at the orbiting facility. The Soyuz 35 crew were the fourth long-duration crew to man the space station.
Soyuz T-4 was a Soviet space mission which launched the crew of Salyut 6 EO-6, the sixth and final long-duration crew of the Salyut 6 space station. It was launched on 12 March 1981 and docked with the station the next day. During their stay, the EO-6 crew was visited by Soyuz 39 and Soyuz 40. Soyuz T-4 returned to Earth on 26 May 1981; its crew were the last to have inhabited Salyut 6.
Soyuz T-5 was a human spaceflight into Earth orbit to the then new Salyut 7 space station in 1982. While the Soyuz-T was docked it received visits from the uncrewed Progress 13 resupply spacecraft, and the crewed Soyuz T-6 and Soyuz T-7.
Soyuz T-6 was a human spaceflight to Earth orbit to the Salyut 7 space station in 1982. Along with two Soviet cosmonauts, the crew included a Frenchman, Jean-Loup Chrétien.
Soyuz T-9 was the 4th expedition to Salyut 7 following the failed docking of Soyuz T-8. It returned lab experiments to Earth. The next mission, Soyuz 7K-ST No.16L, had exploded and thus failed to launch.
Soyuz T-12 was the seventh crewed spaceflight to the Soviet space station Salyut 7. The name "Soyuz T-12" is also the name of the spacecraft used to launch and land the mission's three-person crew. The mission occurred in July 1984, during the long-duration expedition Salyut 7 EO-3. During the mission, crew member Svetlana Savitskaya became the first woman to ever perform a spacewalk, and the potential Buran space shuttle pilot, Igor Volk, was given spaceflight experience. Unlike many Soyuz visiting missions, the Soyuz lifeboats were not swapped, and the crew returned to Earth in the same spacecraft in which they launched.
Soyuz T-15 was a crewed mission to the Mir and Salyut 7 space stations and was part of the Soyuz programme. It marked the final flight of the Soyuz-T spacecraft, the third generation Soyuz spacecraft, which had been in service for seven years from 1979 to 1986. This mission marked the first time that a spacecraft visited, and docked with, two space stations in the same mission.
Soyuz 7K-OK was the first generation of Soyuz spacecraft and was flown between 1967 and 1971. The 7K-OK was used for the first ferry flights to the Salyut space station program, beginning a long history of space station service that continues today with the International Space Station (ISS).
Progress 2 was an unmanned Progress cargo spacecraft launched by the Soviet Union in 1978 to resupply the Salyut 6 space station. It used the Progress 7K-TG configuration, and was the second Progress mission to Salyut 6. It carried supplies for the EO-2 crew aboard Salyut 6, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres.
Mir EO-2 was the second long duration expedition to the Soviet space station Mir, and it lasted from February to December 1987. The mission was divided into two parts, the division occurring when one of the two crew members, Aleksandr Laveykin, was replaced part way through the mission by Aleksandr Aleksandrov. Laveykin was replaced because ground-based doctors had diagnosed him with minor heart problems.
Progress 19 was a Soviet uncrewed Progress cargo spacecraft, which was launched in February 1984 to resupply the Salyut 7 space station.
