KENNEDY SPACE CENTER, FLA. -- The STS-118 crew arrives at Kennedy Space Center's Shuttle Landing Facility to prepare for launch on Aug. 8 aboard Space Shuttle Endeavour. Seen here is Mission Specialist Dave Williams, with the Canadian Space Agency. Endeavour's STS-118 mission is the 22nd shuttle flight to the International Space Station. It will continue space station construction by delivering a third starboard truss segment, S5. Other payloads include the SPACEHAB module, making its last voyage, and the external stowage platform 3 with a control moment gyroscope on it. The flight will include at least three spacewalks. The crew will also debut a new system that enables docked shuttles to draw electrical power from the station to extend visits to the outpost. Photo credit: NASA/Kim Shiflett
