One of four rudder speed brake actuators is lifted for transfer to a pallet where it will be X-rayed. The actuators, to be installed on the orbiter Discovery, are being X-rayed at the Radiographic High-Energy X-ray Facility at Cape Canaveral Air Force Station to determine if the gears were installed correctly. Discovery has been assigned to the first Return to Flight mission, STS-114, a logistics flight to the International Space Station.
