Astronaut and veteran Scott Kelly, 51, is preparing to live a full year in the international space station in order to study the impact a year in space could have physically, mentally, and emotionally. The objectives of this mission are to study the potential biological, as well as psychological, impacts of prolonged time in space on a human being. This mission could have broader implications as NASA looks to the future in creating space stations for human beings, as well as possible hubs on the moon where individuals would live and work.
