In the Space Station Processing Facility, members of the STS-118 crew look over the control moment gyro (CMG) that is part of the payload on their mission. At left is Commander Scott Kelly; at right is Mission Specialist Tracy Caldwell. The CMG will replace a faulty one on the International Space Station. The payload also includes the SPACEHAB single cargo module, the third starboard truss segment (ITS S5) and the external stowage platform 3 (ESP3). STS-118 is targeted to launch June 28 from Launch Pad 39A. Photo credit: NASA/Kim Shiflett
