NASA astronaut Chris Ferguson, STS-135 commander, takes a photo of himself with astronaut Mike Fossum before the crew of the final shuttle mission trains March 10, 2011 in the Neutral Buoyancy Laboratory near the Johnson Space Center in Houston. Fossum will fly to the International Space Station aboard a Russian Soyuz spacecraft scheduled for launch in May and will serve as flight engineer for Expedition 28 and as commander for Expedition 29. Since the crew of the final shuttle mission will consist of only four astronauts, the ISS crew will perform the mission's single scheduled spacewalk, and the crew of STS-135 will function in support of the EVA, with Rex Walheim serving as the internally-based 'quarterback' for the spacewalk.
