MISSION: STS-103 -- 3rd HUBBLE SPACE TELESCOPE SERVICING MISSION

VEHICLE: Discovery/OV-103
LOCATION: Pad 39B
TARGET KSC LAUNCH DATE/TIME: no earlier than December 16 at 9:18 p.m. EST
TARGET KSC 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 ½-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.
