The crew of mission STS-115 stop to talk to the media after arriving at NASA Kennedy Space Center's Shuttle Landing Facility to prepare for launch on Aug. 27 to the International Space Station. Seen here, left to right, are Mission Specialists Steven MacLean and Daniel Burbank, Pilot Christopher Ferguson, Commander Brent Jett, and Mission Specialists Heidemarie Stefanyshyn-Piper and Joseph Tanner. The mission will deliver and install the 17-and-a-half-ton P3/P4 truss segment to the port side of the integrated truss system on the orbital outpost. The truss includes a new set of photovoltaic solar arrays. When unfurled to their full length of 240 feet, the arrays will provide additional power for the station in preparation for the delivery of international science modules over the next two years. STS-115 is expected to last 11 days and includes three scheduled spacewalks. Photo credit: NASA/Kim Shiflett
