In the Orbiter Processing Facility, workers on the floor prepare to attach a crane to the body flap for the orbiter Atlantis. The crane will lift the body flap for installation on the orbiter. The body flap is an aluminum structure consisting of ribs, spars, skin panels and a trailing edge assembly. It thermally shields the three Space Shuttle Main Engines during entry and provides the orbiter with pitch control trim during its atmospheric flight after entry. Atlantis is being processed for its mission, designated STS-121, this summer to the International Space Station. The launch planning window is July 12 - August 3.
