KSC SPACE SHUTTLE PROCESSING STATUS REPORT
-----------------------------------------------------------------
STS-39 -- Discovery (OV 103) - OPF Bay 1
Scheduled operations continue in the Orbiter Processing
Facility today. Water spray boiler servicing is complete and
hydraulic operations continue in progress. Yesterday, brake anti-
skid tests and landing gear functional tests were completed.
Discovery's twin orbital maneuvering system pods will continue to
be checked today. Sleep station installation operations are
currently in work. During helium purge operations last night,
engineers determined there may have been hydraulic fluid
introduced into the high pressure oxidizer turbopump on main
engine number three. Crews will analyze the potential problem and
make further evaluations tomorrow. Rollout of the vehicle to the
Vehicle Assembly Building remains scheduled for no earlier than
January 29.
STS-37 -- Atlantis (OV-104) - OPF Bay 2
Hydraulic fill and bleed operations were conducted
successfully last night along with checks of the nose wheel
steering mechanism. Hydraulic operations will continue throughout
the remainder of the week. Main engine installation is currently
scheduled to begin this weekend. Preparations are in work today
for this operation.
In the Vehicle Assembly Building high bay 3, build up of the
right solid rocket booster segments continue on the mobile
launcher platform. The right aft center segment will be delivered
to the VAB today.
STS-40 -- Columbia (OV 102) - VAB High Bay 2
The ground service equipment was installed in the payload
bay last night as crews today continue with plans to remove the
provisions stowage assembly (PSA) from the bay. Preparations also
continue to access the dump line nozzle for failure analysis.
Columbia is scheduled to be moved to the Orbiter Processing
Facility later this month following the rollover of Discovery to
the VAB.
