In the Orbiter Processing Facility, STS-117 Mission Specialists (left) Patrick Forrester, Steven Swanson and (right) James Reilly take a close look at the wheel well on orbiter Atlantis, their vehicle for the mission. They and other crew members are at KSC to take part in a Crew Equipment Interface Test that allows them opportunities to become familiar with equipment and hardware for their mission. STS-117 will deliver the S3/S4 and another pair of solar arrays to the space station. The 21st shuttle mission to the International Space Station, STS-117 is scheduled to launch no earlier than March 16. Photo credit: NASA/Kim Shiflett
