Baikonur Cosmodrome Site 31

Site 31/6 at the Baikonur Cosmodrome is a launch site used by derivatives of the R-7 Semyorka missile. From 2011 onwards, it was supposed to be the launch site for manned Soyuz missions to the International Space Station, when launches switched from the Soyuz-FG carrier rocket to the Soyuz-2, which was unable to use the launch pad at Site 1/5. However, Site 1/5 has undergone modifications that allow the manned ISS missions to be launched from it. Soyuz TMA-06M is so far the only manned mission to the International Space Station to be launched from Site 31/6.

It was first used on 14 January 1961, for an R-7A ICBM test mission. It is currently used for commercial Soyuz-FG/Fregat missions, and Soyuz-2 launches. In the 1970s and early 1980s, several manned missions were launched from the site.

After several years a new manned spaceflight was conducted from LC31. Soyuz TMA-06M was launched on 23 October 2012.
