Work in progress: Space Shuttle managers today completed a review of Shuttle
Discovery’s readiness for flight on mission STS-103. They maintained a
launch date of Dec. 9 for Discovery, although a further review of work
remaining to close-out Discovery for flight will be held later this week.
The launch date may be adjusted slightly pending the status of remaining
work that is reported at that time.

At the launch pad, workers completed replacement of Discovery’s mass memory
unit No. 1. Close-out work on the recently repaired orbiter/external tank
umbilical wiring harness continues as engineers conduct validation tests on
that system. Tonight, workers are slated to begin Shuttle ordnance
installation and replacement of a leaky quick disconnect on auxiliary power
unit No. 2 is planned for later this week. Routine orbiter aft compartment
close-outs continue along with wiring inspections.
