Scott KellyHaving traveled to the International Space Station as part of the Expedition 43 crew, astronaut Scott Kelly and cosmonaut Mikhail Korniyenko return to Earth after their heavily-publicized “One-Year Mission”, along with cosmonaut Sergey Volkov. Though the duration of the “One-Year Mission” is closer to 11 months, Kelly has broken the American record for continuous time spent in space. NASA hopes medical data gathered during his stay will help to keep future astronauts healthy, both physically and mentally, on long-term flights to such future destinations as Mars.
