Expedition 46 Commander Scott Kelly of NASA and cosmonauts Sergey Volkov and Mikhail Kornienko of Roscosmos landed safely in Kazakhstan on March 2. The landing wrapped up a 340 day mission aboard the International Space Station for Kelly and Kornienko, during which they gathered valuable biomedical data on the long duration effects of weightlessness on the human body that will be used to formulate a human mission to Mars.
