In the Orbiter Processing Facility, STS-117 Pilot Lee Archambault (left) and Mission Specialist James Reilly (second from right) look at a part of the external airlock in the payload bay of Atlantis. 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
