US astronaut Scott Kelly (R) and Russian cosmonauts Sergei Volkov (center) and Mikhail Korniyenko, surrounded by ground personnel, rest shortly after landing near the town of Dzhezkazgan (Zhezkazgan), Kazakhstan, on

Wednesday. Kelly and Kornienko had been aboard the space station for 340 days, about twice as long as previous crews. Their flight set a record for the space station and for the longest US space mission. Throughout their nearly year-long stay in space, Kelly, 52, and Kornienko, 55, have been the subjects for dozens of medical experiments and science studies designed to learn more about how weightlessness and the high radiation environment of space affect the human body.
