INTERNATIONAL SPACE STATION -- The Expedition 16 crew officially turned over control of the International Space Station to the Expedition 17 crew, which recently arrived to the station on board a Soyuz rocket.
It's been quite a mission for Expedition 16 commander Peggy Whitson.
Whitson was the station's first female commander and is now the record holder for the most time in space by a U.S. astronaut.
The old crew is set to land back on Earth on Saturday in Kazakhstan.
