About this work
Kennedy Space Center, Fla. — 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.
