Soyuz program

The Soyuz programme (/ˈsɔɪjuːz/ or /ˈsɔːjuːz/; Russian: Союз [sɐˈjus], meaning "Union") is a human spaceflight programme that was initiated by the Soviet Union in the early 1960s, originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon. It was the third Soviet human spaceflight programme after the Vostok and Voskhod programme.

The programme consists of the Soyuz spacecraft and the Soyuz rocket and is now the responsibility of the Russian Federal Space Agency. Since the retirement of the Space Shuttle in 2011, all human spaceflights to and from the International Space Station have been carried out using Soyuz.

The launch vehicles used in the Soyuz expendable launch system are manufactured at the Progress State Research and Production Rocket Space Center (TsSKB-Progress) in Samara, Russia. As well as being used in the Soyuz programme as the launcher for the manned Soyuz spacecraft, Soyuz launch vehicles are now also used to launch unmanned Progress supply spacecraft to the International Space Station and commercial launches marketed and operated by TsSKB-Progress and the Starsem company. There were 11 Soyuz launches in 2001 and 9 in 2002. Currently Soyuz vehicles are launched from the Baikonur Cosmodrome in Kazakhstan and the Plesetsk Cosmodrome in northwest Russia and, starting in 2011, Soyuz launch vehicles can now also be launched from the Guiana Space Centre in French Guiana. The Spaceport’s new Soyuz launch site has been handling Soyuz launches since 21 October 2011, the date of the first launch. As of July 2014, 8 Soyuz launches had been made from French Guiana, all successful.
