Expedition 20

Expedition 20 is the 20th long duration flight to the International Space Station. This expedition started May 27 2009, 10:34 GMT. Because, for the first time, six crew members will be at the station, there will be two separate Soyuz TMA flights launched at two different times (each Soyuz TMA can hold only three people) : Soyuz TMA-14 in March 2009 and Soyuz TMA-15 in May 2009.

Gennady Padalka will be the first commander of a six-crew ISS and the first commander of two consecutive expeditions (Expedition 19 and 20). Nicole Stott will be the final expedition astronaut to be launched on the Shuttle.
