Reisman will launch to the International Space Station on the STS-123 mission of Endeavour in March 2008, joining Expedition 16 in progress and will provide Expedition 17 with an experienced flight engineer for the first part of its increment. Volkov and Kononenko are scheduled to launch to the complex in the Soyuz TMA-12 spacecraft from the Baikonur Cosmodrome in Kazakhstan in April for a six-month mission. Reisman is scheduled to be replaced in June by NASA astronaut Greg Chamitoff.
