Salyut 6

Salyut 6 was a Soviet space station, which was launched on September 29, 1977 with a Proton rocket. Based on the design of the previous types of DOS / OPS ranks they had some revolutionary innovations, such as the second docking port at the rear. This allowed for the first time Progress supply spacecraft to dock with the station and provide them with fuel and other freight. With Salyut 6 long-term missions were so first time.

Between 1977 and 1982 the station was visited by six long-term and eleven visiting teams, including in the framework of the Intercosmos program for the first time by astronauts from other countries. Already the first long-duration crew of Salyut 6 broke with a stay of 96 days, the former, in 1973/74 laid down on board the U.S. station Skylab record. The longest stay on board lasted 185 days. The fourth long-term crew installed a 10 - meter radio telescope antenna. In 1981, coupled with a Cosmos 1267 TKS spacecraft of the military Alma's program for testing purposes at the station. This gave Salyut 6, the basis for the construction of a modular space station. However, the use of the complex by a crew could not be performed because the last crew Salyut 6 had already left before coupling of Cosmos 1267. Salyut 6 was launched on 29 July 1982 controlled crash over the South Pacific.

Salyut -6 expeditions

The first planned long-term crew launched on Soyuz 25 to Salyut 6 reached after two days Vladimir Kovalyonok and Valeri Rjumin the station, but could not link up because of a failure of the automatic system approach to their spaceship.

Salyut 6 had then a total of six long-term crews. On December 10, 1977, the first resident crew reached Salyut 6 EO - 1, consisting of Yuri Romanenko and Georgi Grechko, Soyuz 26, the station and stayed 96 days. The second long-term crew Salyut 6 EO -2 ( Vladimir and Alexander Kovalyonok Ivanchenkov in Soyuz 29) docked on June 15, 1978 addressed to the station and lived and worked there 140 days. Vladimir Liakhov and Valeri Rjumin came with Soyuz 32 on 25 February 1979 and formed the crew station Salyut 6 EO - third They stayed 175 days. The fourth long-term crew Salyut 6 EO -4 on Soyuz reached 35, 9 April 1980 Salyut 6 crew conducted with 185 days the longest stay in space by and consisted of Leonid Popov and Valery Rjumin. The next mission Salyut 6 EO -5 was a repair mission and lasted only twelve days. Leonid Kizim, Oleg Makarov and Gennadi Strekalow came with Soyuz T -3 on 27 November 1980 on the station. On March 12, 1981 attended the last regular team Salyut 6 EO -6, consisting of Vladimir Kovalyonok and Viktor Savinykh, the space station and stayed 75 days.

Besides visited a total of ten crews for short -term missions ( Salyut 6 EP- 1 to Salyut 6 EP-10 ) the Salyut 6 space station and brought supplies and partly spaceman with other nations as part of the Intercosmos program.
