Expedition 20

Expedition 20 was a 2009 International Space Station resident increment that marked the station's transition to routine six-person operations. The expedition brought together crew members arriving by Soyuz and Space Shuttle, including long-duration residents from Russia, the United States, Japan, Belgium, Canada, and later a Shuttle-delivered NASA crew rotation. During the increment the station supported Kibo completion work, the first HTV cargo vehicle, visiting Shuttle missions STS-127 and STS-128, Progress logistics traffic, and Russian-segment preparations for the Poisk module. Gennady Padalka commanded the expedition, with Michael Barratt, Koichi Wakata, Roman Romanenko, Robert Thirsk, Frank De Winne, Timothy Kopra, and Nicole Stott serving across the rotating flight-engineer seats.
