NASA Astronaut Scott Kelly is seen inside a Soyuz simulator at the Gagarin Cosmonaut Training Center (GCTC), in Star City, Russia, March 4, 2105.

NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko returned to Earth on Wednesday after nearly a year on the International Space Station.

A Soyuz capsule carrying Kelly, Kornienko and Sergey Volkov, another Russian cosmonaut, made a parachute landing on the steppe near the Kazakh city of Zhezkazgan.

Kelly and Kornienko have been aboard the space station for 340 days, about twice as long as previous crews. Their flight sets a record for the space station and for the longest U.S. space mission.
