Expedition 22 was 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.
