KENNEDY SPACE CENTER, FLA. -- 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. Second from left is Mission Specialist Tracy Caldwell; at right are Mission Specialists Richard Mastracchio (pointing) and Clayton Anderson, who will be flying on STS-118 to join the Expedition 15 crew as flight engineer on the International Space Station. 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 KSC-07pd0230

STS117-S-014 (8 June 2007) --- Through the large windows in the Launch Control Center, NASA officials watch the launch of Space Shuttle Atlantis on mission STS-117. Atlantis and its seven-member crew head toward Earth-orbit and a scheduled link-up with the International Space Station. Liftoff from Kennedy Space Center's launch pad 39A occurred at 7:38 p.m. (EDT) on June 8, 2007. Onboard are astronauts Rick Sturckow, commander; Lee Archambault, pilot; Jim Reilly, Patrick Forrester, John "Danny" Olivas, Steven Swanson and Clayton Anderson, all mission specialists. Anderson will join Expedition 15 in progress to serve as a flight engineer aboard the station. Atlantis will dock with the orbital outpost on Sunday, June 10, to begin a joint mission that will increase the complex's power generation capability. Using the shuttle and station robotic arms and conducting three scheduled spacewalks, the astronauts will install another set of giant solar array wings on the station and retract another array, preparing it for a future move.
