Before dawn, at the Shuttle Landing Facility, or SLF, at NASA's Kennedy Space Center in Florida, space shuttle Endeavour is lowered toward the ground by the sling in the mate/demate device. Visible on Endeavour is the tail cone that covers and protects the main engines during the ferry flight. After Endeavour is on the ground, it will be towed via the two-mile tow-way from the SLF by a diesel-powered tractor to the Orbiter Processing Facility where it will begin preparations for its next mission, STS-127, targeted for May 2009.
