Soyuz programme
(Manned missions)

Soyuz TMA-20 was a human spaceflight to the International Space Station (ISS) and was part of the Soyuz programme. It lifted off from the Baikonur Cosmodrome in Kazakhstan on December 15, 2010, and docked with the ISS two days later. The three-person crew of Soyuz TMA-20 – Dmitri Kondratyev, Catherine Coleman and Paolo Nespoli – represented the ISS partner organizations of Roscosmos, NASA and the European Space Agency (ESA). Soyuz TMA-20's crew represented half of the members of Expedition 27; the other three members of the expedition arrived at the station on board Soyuz TMA-21 on April 6, 2011. The COSPAR ID of Soyuz TMA-20 was 2010-067A.[5] It is ISS flight 25S.

On May 24, 2011, after spending 159 days in space, the Soyuz TMA-20 descent module landed safely in Zhezkazgan, Kazakhstan, carrying Kondratyev, Coleman and Nespoli.


The Soyuz TMA-20 prime and backup crews conduct their ceremonial tour of Red Square on November 26, 2010.

The Soyuz TMA-20 crew was confirmed by NASA on November 21, 2008.[3]

Tallest-ever crew member

European astronaut Paolo Nespoli was believed to have been the tallest crew member to date ever to fly aboard a Soyuz spacecraft, with a height of 188 centimeters (6 ft 2in). According to the president of RKK Energia, Vitaly Lopota, a custom-built seat and related hardware had to be manufactured to accommodate Nespoli's height.
