Expedition 20

Expedition 20 was the twentieth long-term mission to the International Space Station and the first to house six crew members at once. Two separate Soyuz launches were needed because each spacecraft could carry only three people. Gennady Padalka became the first commander of a six-person station crew and the first to lead two back-to-back expeditions. Nicole Stott was the last expedition astronaut to ride a shuttle into orbit.
