NOTE: Retests of Discovery's replaced master event controller and multiplexer/demultiplexer were successfully completed yesterday. Aft compartment close-outs continue in preparation for testing of the first super lightweight external tank. Liquid hydrogen loading is slated to begin Monday at about 7 a.m. and liquid oxygen loading follows at 10:20 a.m. SPACEHAB interface verification testing is complete and the AMS IVT is scheduled to begin this afternoon. Following the AMS IVT, Discovery's payload bay doors will be closed. The Rotating Service Structure will be retracted on Sunday in preparation for the tanking test. STS-91 SCHEDULED OPERATIONAL MILESTONES (dates are target only):  STS-88 -- FIRST FLIGHT INTERNATIONAL SPACE STATIONNODE-1 (Unity) NOTE: Endeavour's radiators are stowed in the orbiter's midbody and the payload bay doors have been closed to support inspections. Hydraulic leak checks of the main landing gear struts are in work.  STS-93 -- Advanced X-ray Astrophysics Facility (AXAF)
NOTE: Preparations for Columbia's hypergolic deservicing are complete. Removal of the Spacelab tunnel forward extension is also complete. Draining of the orbiter maneuvering system propellant tanks is under way.
