Expedition 27
Expedition 27 was the 27th long-duration expedition to the International Space Station , starting on 16 March 2011. Expedition 27 saw numerous notable events, including the undocking of the Progress M-09M and Kounotori 2 spacecraft, the arrival of the Soyuz TMA-21 and Progress M-10M spacecraft, and...



Progress M-10M lifted off from launch pad number 1 of the Baikonur cosmodrome at 13:05 UTC on 27 April 2011. Progress M-10M achieved the preliminary planned orbit after nine minutes of the launch. Onboard commands were issued to unfurl the spacecraft's communications and navigation antennas and extend two power-generating solar arrays. A series of engine firings over the next two days guided the spacecraft toward a linkup with the International Space Station (ISS).


Progress M-10M autonomously flew for two days after the launch and arrived at the ISS on 29 April 2011, successfully docking to the nadir port of the Pirs at 14:19 UTC. The docking occurred as the two spacecraft were traveling 220 miles (354 kilometers) over western Mongolia. The linkup happened just over five hours before NASA's first launch attempt of the Space Shuttle Endeavour

Undocking and decay

Progress M-10M undocked nominally at 9:04 GMT on 29 October 2011 from the Nadir port of the Pirs Docking Compartment after hooks open command at 9:01 GMT. An automated 15 seconds separation burn followed at 9:07 GMT. The cargo ship, loaded with trash, performed its 3 minute deorbit burn at 12:10:30 GMT. It entered the Earth's atmosphere at 12:48 PM GMT and burned up at 12:54 PM GMT. Surviving debris impacted in the Pacific Ocean
