The launch of the Soyuz TMA-22 spacecraft was postponed from the end of September to November 14, 2011 due to the unsuccessful launch of the Progress M-12M unmanned cargo spacecraft on August 24, 2011. The cause of the incident was a clogged fuel line leading to the engine gas generator of the third stages RD-0110 of the upper stage of the Soyuz-U spacecraft. After the loss of the Progress M-12M, all Russian manned space flights were temporarily suspended due to the similarity between the failed engine and the third stage engine used on the Soyuz-FG manned launch vehicle. On October 30, 2011, Russia successfully launched the Progress M-13M cargo spacecraft on a Soyuz-U launch vehicle, thus clearing the way for the launch of the Soyuz TMA-22 spacecraft.
