KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
TUESDAY, JANUARY 10, 1995 (12:10 PM EST)

MISSION: STS-63 -- MIR RENDEZVOUS, SPARTAN and SPACEHAB-3

VEHICLE: Discovery/OV-103
LOCATION: Vehicle Assembly Building
TARGET LAUNCH DATE/TIME: Feb. 2, 1995 at 12:51 a.m. EST
LAUNCH WINDOW: 5 minutes
TARGET KSC LANDING DATE/TIME: Feb. 10 at 7:05 a.m.
MISSION DURATION: 8 days, 6 hours, 13 minutes
CREW SIZE: 6
ORBITAL ALTITUDE and INCLINATION: 196-245 statute miles/51.60 
degrees

NOTE: Managers decided last night to roll out the Shuttle 
Discovery to pad 39 B a day early. First motion is scheduled for
11:30 a.m. today. The decision to roll early was made when the pressure
in a right hand orbital maneuvering system pod oxidizer manifold dropped
from 150 psi to about 15 psi. The manifold serves 4 of the orbital
maneuvering system thrusters on the right hand pod. One of these thrusters 
(R3A) has a documented very minor leak which was managed and 
controlled during the past two flights. However, from the time 
the orbiter left the Orbiter Processing Facility (Jan. 5) to the 
time it was first powered up in the Vehicle Assembly Building, 
the manifold pressure dropped significantly. Engineers think this 
radical drop was caused by cold weather effects on the thruster's 
seal this past weekend. Last night, the manifold pressure was 
brought up to about 65 psi in the Vehicle Assembly Building, the 
maximum available with equipment in the Vehicle Assembly 
Building. Once at the pad, the manifold pressure can be returned 
to the standard 150 psi. Low pressure in the manifold over a 
period of time may cause other thruster seals to dry-out and 
leak. Later this week, engineers will decide if thruster R3A must be
replaced.

IN WORK TODAY:
  Rollout to pad 39B scheduled for 11:30 a.m. today

WORK COMPLETED:
  Shuttle interface verification tests

WORK SCHEDULED:
  Launch pad validations
  Main engine preparations and frequency response test

KEY OPERATIONAL MILESTONES SCHEDULED FOR JANUARY (dates are targeted only):
  Terminal Countdown Demonstration Test (Jan. 17-19)
  Flight Readiness Review (Jan. 18)
  Hot fire auxiliary power unit no. 2 (Jan. 22)

LOCATION: OPF bay 1
TARGET LAUNCH PERIOD: early March
APPROX. LAUNCH TIME: very early morning
LAUNCH WINDOW: 2 hours, 3 minutes
KSC LANDING DATE/TIME: TBD
MISSION DURATION: 15 days, 13 hours
CREW SIZE: 7
ORBITAL ALTITUDE and INCLINATION: 218 statute miles/28.45 degrees

IN WORK TODAY:
