Mission highlights

Soyuz TMA-22 departure

Expedition 31 formally began on 27 April 2012, with the departure from the ISS of the Soyuz TMA-22 spacecraft. Soyuz TMA-22 successfully returned Expedition 30 astronauts Dan Burbank, Anton Shkaplerov and Anatoli Ivanishin to Earth.[1] The ISS was left under the command of astronauts Kononenko, Kuipers and Pettit, who had arrived at the station aboard Soyuz TMA-03M on 23 December 2011.

Soyuz TMA-04M arrival

The final three members of Expedition 31 – Acaba, Padalka and Revin – arrived at the ISS aboard Soyuz TMA-04M, which launched on 15 May 2012,[7] and docked to the ISS on 17 May at 4:36 UTC.[8]

SpaceX Dragon test mission

SpaceX's unmanned Dragon spacecraft conducted a test rendezvous with the ISS during Expedition 31, as part of NASA's Commercial Orbital Transportation Services program; it was the first commercial spacecraft to rendezvous with the ISS. Following a series of delays,[9] Dragon launched on 22 May 2012, and berthed successfully with the ISS on 25 May, after conducting a series of orbital test manoeuvres.[10][11] Dragon carried around 544 kilograms (1,199 lb) of cargo to the ISS, including food, clothing, a laptop computer and 15 student experiments.[10][12] After being loaded with 660 kilograms (1,460 lb) of downmass cargo, including completed experiments and redundant equipment, it undocked from the station and returned to Earth on 31 May 2012.[13][14] Dragon landed intact in the Pacific Ocean and was successfully recovered, allowing SpaceX to begin regular cargo flights to the ISS.[15] The first such logistics mission, CRS SpX-1, launched successfully in October 2012.[16][17]

Soyuz TMA-03M departure

Soyuz TMA-03M departed from the ISS on 1 July 2012, successfully returning Kononenko, Kuipers and Pettit to Earth. Their departure marked the formal end of Expedition 31, and the beginning of Expedition 32.[2]

In popular culture

In the 2012 The Big Bang Theory episode "The Friendship Contraction", character Howard Wolowitz revealed that he would be a member of a fictionalized Expedition 31.[18]
