Salyut 7 was launched on April 19, 1982, the last of the Salyut space station program. It was the back-up vehicle for Salyut 6 and very similar in equipment and capabilities, though several more advanced features were included. It was aloft for four years and two months, during which time it was visited by 10 crews constituting 6 main expeditions and 4 secondary flights (including French and Indian cosmonauts). Aside from the many experiments and observations made on Salyut 7, the station also tested the docking and use of large modules with an orbiting space station. The modules were called "Heavy Cosmos modules." They helped engineers develop technology necessary to build Mir. Salyut 7 deorbited on February 7, 1991.
It had two docking ports, one on either end of the station, to allow docking with the Progress unmanned resupply craft, and a wider front docking port to allow safer docking with a Heavy Cosmos module. It carried three solar panels, two in lateral and one in dorsal longitudinal positions, but they now had the ability to mount secondary panels on their sides. Internally, the Salyut 7 carried electric stoves, a refrigerator, constant hot water and redesigned seats at the command console (more like bicycle seats). Two portholes were designed to allow ultraviolet light in, to help kill infections. Further, the medical, biological and exercise sections were improved, to allow long stays in the station. The BST-1M telescope used in Salyut 6 was replaced by an X-ray detection system.

Crews and missions

Following up the use of Cosmos 1267 on Salyut 6, the Soviets launched Cosmos 1443 on March 2, 1983, from a Proton SL-13. It docked with the station on March 10, and was used by the crew of Soyuz T-9. It jettisoned its recovery module on August 23, and re-entered the atmosphere on September 19. Cosmos 1686 was launched on September 27, 1985, docking with the station on October 2. It did not carry a recovery vehicle, and remained connected to the station for use by the crew of Soyuz T-14. Ten Soyuz T crews operated in Salyut 7. Only two InterCosmos "guest cosmonauts" worked in Salyut 7. Soyuz T-10 was aborted on the launch pad when a fire broke out at the base of the vehicle. The payload was ejected, and the crew was recovered safely. Salyut 7 had six resident crews. The first crew, Anatoli Berezovoy and Valentin Lebedev, arrived on May 13 1982 on Soyuz T-5 and remained for 211 days until December 10 1982. On June 27 1983 the crew of Vladimir Lyakhov and Alexander Alexandrov arrived on Soyuz T-9 and remained for 150 days, until November 23 1983. On February 8 1984 Leonid Kizim, Vladimir Solovyev, and Oleg Atkov began a 237 day stay, the longest on Salyut 7, which ended on October 2 1984. Vladimir Dzhanibekov and Viktor Savinykh (Soyuz T-13) arrived at the space station on June 6 1985. On September 17 1985 Soyuz T-14 docked with the station carrying Vladimir Vasyutin, Alexander Volkov, and Georgi Grechko. Eight days later Dzhanibekov and Grechko left the station and returned to Earth after 103-days, while Savinyikh, Vasyutin, and Volkov remained on Salyut 7 and returned to Earth on November 21 1985 after 65-days. On May 6 1986 Soyuz T-15 carrying Leonid Kizim and Vladimir Soloviyov docked with the space station. The Soyuz had come from the Mir space station and returned to Mir after a 50 days days on Salyut. There were also four visiting missions, crews which came to bring supplies and make shorter duration visits with the resident crews.
