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

NOTE: Launch of Space Shuttle Discovery remains set for about 12:48 a.m. Thursday, Feb. 2. The countdown will target launch for 12:45 a.m., the earliest possible launch opportunity based on the Mir orbit. The exact launch time will be adjusted at the T-9 minute hold.

VEHICLE: Discovery/OV-103
LOCATION: Pad 39B
LAUNCH DATE/APPROX. TIME: Feb. 2, 1995 at 12:48 a.m. EST
LAUNCH WINDOW: 5 minutes
KSC LANDING DATE/TIME: Feb. 10 at 6:13 a.m.
MISSION DURATION: 8 days, 5 hours, 25 minutes
ORBITAL ALTITUDE and INCLINATION: 196-245 statute miles/51.60 degrees

The countdown for mission STS-63 and the launch of Discovery Thursday morning continues as planned today. The countdown began Sunday at 4:30 p.m. at the T-43 hour mark.
The pad was cleared yesterday for loading the onboard cryogenic tanks with the liquid hydrogen and liquid oxygen reactants.
Reactant loading was concluded yesterday evening. The reactants will provide electricity for the orbiter and crew while in space and drinking water as a by-product during their 8-day mission.
After the cryogenics were loaded, the orbiter's mid-body umbilical unit was demated and retracted into the fixed service structure. Final vehicle and facility close-outs are now underway and the orbiter's communications systems and inertial measurement units are being activated today. Final Spacehab stowage will be completed later today.
Tomorrow, preparations will be made to retract the rotating service structure to launch position at about 8 a.m. Loading of the external tank with cryogenic propellants is scheduled to begin at about 3:55 p.m. Wednesday.
Air Force weather forecasters are currently indicating a zero percent probability of weather prohibiting launch on Thursday. During Thursday's five minute launch window, the winds at Pad B are expected to be from the west at 10-15 knots; temperature 48 degrees F; visibility 7 miles; and clouds scattered at 25,000- 28,000 feet. The 24-hour-delay forecast reveals similar conditions with forecasters again listing a zero percent chance of violation.
The six-member astronaut crew arrived at KSC's Shuttle Landing Facility at about 11:40 p.m. Sunday. Today they will be involved with checking out their mission plans, fit checks of their equipment and flights in the Shuttle Training Aircraft.
