HOUSTON — Three International Space Station crew members safely returned to Earth on Monday, wrapping up nearly six months in space during which NASA and its international partners celebrated the 11th anniversary of continuous residence and work aboard the station.

Expedition 29 Commander Mike Fossum, Flight Engineers Satoshi Furukawa of the Japan Aerospace Exploration Agency and Sergei Volkov of the Russian Federal Space Agency landed their Soyuz spacecraft in frigid conditions on the central steppe of Kazakhstan at 8:26 p.m. CST Nov. 21 (8:26 a.m. Kazakhstan time, Nov. 22). The trio arrived at the station on June 9. They spent 167 days in space and 165 days on the complex. Volkov, a two-time station crew member, now has accumulated 366 days in space.

Before leaving the station, Fossum handed over command to NASA’s Dan Burbank, who leads Expedition 30. Burbank and Flight Engineers Anatoly Ivanishin and Anton Shkaplerov of Russia will continue research and maintenance aboard the station.

The remaining Expedition 30 crew members, NASA astronaut Don Pettit, European Space Agency astronaut Andre Kuipers, and cosmonaut Oleg Kononenko, are scheduled to launch Dec. 21 from the Baikonur Cosmodrome and dock with the station on Dec. 23.
