In the Orbiter Processing Facility, STS-117 Pilot Lee Archambault (left) and Mission Specialist James Reilly (right) look over 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
