Kelly and Kornienko will spend a year in space and return to Earth on Soyuz TMA-18M in March 2016. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. This knowledge is critical as NASA looks toward human journeys deeper into the solar system, including to and from Mars, which could last 500 days or longer.
The Soyuz is set to lift off at 3:42 p.m. EDT, Friday, March 27 on a six-hour, four-orbit flight to the station.
