Kelly launched to the space station March 27, 2015, from the Baikonur Cosmodrome in Kazakhstan and is set to return on Tuesday, March 1. He will land in Kazakhstan at 11:27 p.m. (10:27 a.m. Kazakhstan time on March 2) with his one-year crewmate, cosmonaut Mikhail Kornienko of the Russian space agency Roscosmos, and cosmonaut Sergey Volkov, also of Roscosmos. Kelly will return to Houston’s Ellington Field on Wednesday, March 2.

After landing, Kelly will hold the record among U.S. astronauts for cumulative time in space, with 520 days. During their record-setting mission, Kelly and Kornienko participated in a number of studies to provide new insights into how the human body adjusts to weightlessness, isolation, radiation and the stress of long-duration spaceflight, which will include the Journey to Mars. Kelly’s twin brother, former NASA astronaut Mark Kelly, participated in parallel twin studies on Earth to help scientists compare the effects on the body and mind in space.
