Soyuz TMA-22 was a manned spaceflight to the International Space Station (ISS). TMA-22 was the 111th flight of a Soyuz spacecraft, and transported three members of the Expedition 29 crew to the ISS. The spacecraft docked to the ISS on 16 November 2011, and remained docked to serve as an emergency escape vehicle until its undocking on 27 April 2012. Soyuz TMA-22 successfully landed in Kazakhstan on 27 April 2012 11:45 GMT.
TMA-22 was the final flight of a Soyuz-TMA vehicle, following the design's replacement by the modernized TMA-M series. The launch of Soyuz TMA-22 was originally scheduled for 30 September 2011, but was delayed until 14 November following the launch failure of the Progress M-12M resupply vehicle on 24 August 2011. Soyuz TMA-22 was the first manned mission to dock with the ISS since the retirement of the American Space Shuttle fleet at the end of the STS-135 mission in July 2011.
Soyuz TMA-22's launch was rescheduled from late September 2011 to 14 November, due to the failed launch of the unmanned Progress M-12M cargo spacecraft on 24 August 2011. The incident was caused by a blocked fuel line leading to the gas generator of the third-stage RD-0110 engine of the spacecraft's Soyuz-U booster. After the loss of Progress M-12M, all Russian crewed spaceflights were temporarily suspended, due to the similarities between the failed engine and the third-stage engine in use on the crewed Soyuz-FG booster. A Russian commission blamed the Progress M-12M failure on a single human error, and put additional procedures in place to prevent the problem from recurring. On 30 October 2011, Russia successfully launched the unmanned Progress M-13M cargo spacecraft atop a Soyuz-U booster, clearing the way for the Soyuz TMA-22 launch.
