In the Space Station Processing Facility, members of the STS-118 crew learn important information from technicians about the control moment gyro (CMG) in front of them 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
