Expedition 15 commander Fyodor Yurchikhin, flight engineer Oleg Kotov and spaceflight participant Charles Simonyi arrived at the space station in a Soyuz spacecraft Monday afternoon, two days after their launch from the Baikonur Cosmodrome in Kazakhstan.
Simonyi, flying under contract with the Russian Federal Space Agency, is to return to Earth with the Expedition 14 crew on April 20.
