About this work
CAPE CANAVERAL, Fla. – In Orbiter Processing Facility bay No. 2, technicians install auxiliary power unit 3, or APU3, in space shuttle Endeavour for the STS-126 mission. The auxiliary power unit is a hydrazine-fueled, turbine-driven power unit that generates mechanical shaft power to drive a hydraulic pump that produces pressure for the orbiter's hydraulic system. There are three separate APUs, three hydraulic pumps and three hydraulic systems, located in the aft fuselage of the orbiter.
