NASA Kennedy Space Center Technicians Complete Shuttle Leak Tests

Leak checks have been completed on space shuttle Endeavour’s external fuel tank’s ground umbilical carrier, or GUCP, plate at Launch Pad 39A.

Today technicians will focus on connecting the auxiliary power unit (APU) quick disconnects. The APU 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.

Meanwhile, the STS-134 astronauts continue training at their home base at NASA’s Johnson Space Center in Houston in preparation for Endeavour’s launch on the next mission to the International Space Station, which is targeted for April 19.
