KENNEDY SPACE CENTER, FLA. -- Space shuttle Atlantis is revealed on Launch Pad 39A at NASA's Kennedy Space Center after the rotating service structure, or RSS, at left of the pad, has been rolled back. Movement of the RSS began at 7:27 p.m. EST. The RSS provides protected access to the orbiter for crew entry and servicing of payloads at the pad. Rollback of the pad's RSS is one of the milestones in preparation for the launch of mission STS-122, scheduled for 2:45 p.m. EST on Feb. 7. This will be the third launch attempt for Atlantis since December 2007 to carry the Columbus Laboratory to the International Space Station. Beneath the shuttle is the mobile launcher platform which supports the shuttle until liftoff. Photo credit: NASA/Kim Shiflett
