A worker acts as spotter for space shuttle Atlantis as it is backed out from under the work platforms in Orbiter Processing Facility-2 on its move to the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida.

Atlantis will be stored temporarily in the VAB while transition and retirement processing resumes on shuttle Endeavour in the processing hangar. Endeavour is being prepared for public display at the California Science Center in Los Angeles. A groundbreaking was held Jan. 18 for Atlantis' future home -- a 65,000-square-foot exhibit in Shuttle Plaza at the Kennedy Space Center Visitor Complex.
