Shuttle Processing Note: With Atlantis’ rudder/speed brake power drive unit now replaced, preliminary tests indicate a successful change-out. Tomorrow, engineers will confirm that Shuttle Atlantis’ entire hydraulic system is functioning normally with a frequency response test of the orbiter’s aerosurfaces and main engines. Review of the test data will conclude early next week.
Yesterday, workers completed efforts to replace the hydraulic fluid discharge hose on auxiliary power unit No.1 and the electronics box in the orbiter aft compartment. Sunday afternoon, engineers will perform a hotfire test of the APU. Managers have decided to replace a gaseous nitrogen quick disconnect on APU No. 2 next week as well. With a hypergolic pressure test already scheduled as part of standard launch preparations next week, no significant impact to the schedule is expected. Shuttle engineers continue to evaluate the two minor liquid hydrogen line dings. Preliminary analysis suggests that the lines will be acceptable for flight.
SPACEHAB early stow operations are complete and flight crew equipment stowage begins Monday. Next week, engineers begin preparations in the Launch Control Center to pickup the 43-hour launch countdown at 7 p.m. on April 21.
