{description}   United Space Alliance technicians (left to right) Tod Biddle, Bob
                Wright and Mark Noel (hidden) remove the coverings from a site
                near the tail of Space Shuttle Atlantis to reveal the power drive
                unit (PDU) inside. The PDU controls the rudder/speed brake on the
                orbiter. Shuttle managers decided to replace the faulty PDU,
                about the size of an office copy machine, at the launch pad. If
                successful, launch preparations will continue as planned, with
                liftoff targeted for April 24 at 4:15 p.m. on mission STS-101.
                The mission is the third assembly flight for the International
                Space Station, carrying logistics and supplies to the Space
                Station, plus the crew will be preparing the Station for the
                arrival of the Zvezda Service Module, expected to be launched by
                Russia in July 2000. The crew will conduct one space walk to
                perform maintenance on the Space Station.
