Expedition 22 is the 22nd long duration crew flight to the International Space Station (ISS). This expedition began in November 2009 when the Expedition 21 crew departed. For a period of 3 weeks, there were only 2 crew members; it was the first time that had happened since STS-114 had delivered a third person to restore the ISS crew to 3. Commander Jeff Williams and flight engineer Maksim Surayev were joined by the rest of their crew on 22 December 2009, making the Expedition 22 a crew of five.^[1]
The expedition will end when Soyuz TMA-16 undocks in March 2010, and will be immediately followed by Expedition 23.
