A Year in Space

On Friday, astronauts Scott Kelly and Mikhail Kornienko will be launched into space, where they will spend an entire year on the International Space Station. Time is doing a documentary series on Kelly’s stay in space.

On March 27, the veteran of three previous space flights will take off for the International Space Station (ISS) and, along with cosmonaut Misha Kornienko, remain aloft for a full year. Meantime, Scott’s twin brother Mark, a veteran of four space flights, will remain on the ground. The two men with their matching backgrounds, similar health and identical genomes, will serve as the perfect controlled experiment to learn more about how the human body handles weightlessness-and what can be done to minimize the damage during long-term trips to Mars and elsewhere.

The trailer is available here. Kelly and Kornienko will be the fifth and sixth people to spend at least a year in space…cosmonaut Valeri Polyakov spent 437 straight days in space in 1994-5.
