MISSION: STS-103 – 3rd Hubble Space Telescope Servicing Mission

VEHICLE: Discovery/OV-103


TARGET KSC LAUNCH DATE/TIME: No earlier than December 16 at 9:18 p.m.

TARGET LANDING DATE/TIME: December 26 at about 6:40 p.m. EST

LAUNCH WINDOW: 41 minutes

MISSION DURATION: about 9 days and 21 hours

CREW: Brown, Kelly, Smith, Foale, Grunsfeld, Nicollier, Clervoy

ORBITAL ALTITUDE and INCLINATION: 317 nautical miles/28.45 degrees

Work in progress: Shuttle managers today decided to replace a dented main
propulsion system hydrogen line in Space Shuttle Discovery’s engine
compartment. Managers expect the replacement work to take about 3 days,
followed by system retests and final aft compartment close-outs. The
progress of this planned effort will be monitored throughout, but
preliminary assessments reflect a launch date of no earlier than Dec. 16.
Under the current plan, the launch countdown will begin Tuesday, Dec. 14 at
1:30 a.m.

Workers noted a dent in the line during routine aft compartment inspections
Tuesday. The dent measures 12 inches long and about 1/2-inch deep. The line
recirculates hydrogen from the Shuttle main engines back to the external
tank during prelaunch engine conditioning. The section of this manifold
line that requires replacement measures about 6 feet long.

A spare hydrogen recirculation line has already been prepared for
installation. Tomorrow morning, workers at Launch Pad 39B will begin work
to remove the damaged line. Under the current plan, installation of the
replacement line begins Saturday and orbiter aft compartment close-outs
will occur on Monday.

work to day and main propulsion system leak checks follow tomorrow. Space
Shuttle Endeavour is scheduled to roll out of VAB high bay 1 Monday at about
7 a.m. headed for Launch Pad 39A.
