NASA astronaut Scott Kelly and Russian cosmonauts Mikhael Komienko and Gennady Padalka will blast off into space  aboard a Soyuz capsule on March 27. Padalka will return after six months, but Kelly and Komienko will stay for a full year – twice as long as the longest mission to the space station so far. The goal is to gather more data about how long periods of weightlessness affect the human body, including muscle mass, strength, vision and bone density.

At another NASA news conference earlier today, space station officials shared details about the priorities and objectives of the year-long mission, including hundreds of research experiments and numerous spacewalks.
