Welcome Back to Earth.

Expedition 46 Commander Scott Kelly of NASA and cosmonauts Sergey Volkov and Mikhail Kornienko of Roscosmos were greeted during a traditional ceremony in Kazakhstan on Mar. 2, a few hours after landing in their Soyuz TMA-18M spacecraft. Kelly and Kornienko spent 340 days in space, aboard the International Space Station conducting research on the long duration effects of weightlessness on the human body that will be used to formulate a human mission to Mars.
