NASA Astronaut And Russian Cosmonaut Prepare For Year Long Mission To International Space Station

On March 28th, US astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko will launch aboard the Soyuz TMA-16M spacecraft on a historic mission - a year long visit to the International Space Station. The trip, the first of many that will be undertaken before a manned mission to Mars, is a test to gather information about the psychological and physical effects of extended space travel on the human body.
