KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
 
 
THURSDAY, OCTOBER 19, 1995 (10:23 AM EDT)

LAUNCH - 1 DAY

MISSION: STS-73 -- U.S. MICROGRAVITY LABORATORY-2

VEHICLE: Columbia/OV-102
LOCATION: Pad 39B
LAUNCH DATE/TIME: Oct. 20 at 9:50 a.m. (EDT)
LAUNCH WINDOW: 2 hours, 30 minutes
TARGET KSC LANDING DATE/TIME: Nov. 5 at 6:45 a.m. (EST)
MISSION DURATION: 15 days, 21 hours, 55 minutes
CREW SIZE: 7
ORBITAL ALTITUDE and INCLINATION: 172 statute miles/39 degrees

NOTE: Launch of Columbia on mission STS-73 remains on schedule for Friday, Oct. 20. The clock will begin counting at the T-11 hour mark at 7:30 p.m. today, for a scheduled T-0 at 9:50 a.m. on Friday. The launch window extends for 2 1/2 hours. (The available launch period extends until 1:30 p.m. Friday and could be utilized if a decision is made to delay crew entry into the orbiter.)

No technical issues or concerns are being discussed by the mission management team or by NASA engineers at pad 39B. Mission managers will hold a standard launch minus one day meeting at 11:30 a.m. today at KSC to formalize tomorrow’s launch attempt.

At this time, final mid-deck payload loading operations are underway. The rotating service structure will be retracted to launch position at about 2 p.m. today, pending weather. Loading of the external tank with cryogenic propellants is scheduled to begin at about 1:30 a.m. Friday.

Air Force weather forecasters are currently indicating an 60 percent probability of weather prohibiting launch on Friday. A stationary front and upper level low pressure system over Florida are showing signs of weakening. An approaching cold front is expected to move through the KSC area early Saturday. There is less than a 10 percent chance of weather violating tanking constraints during tanking operations early Friday morning.

On Friday, the primary concern is for low clouds and, to a lesser degree, possible crosswind violations at the Shuttle Landing Facility. During Friday’s launch window, the winds at Pad 39B are expected to be from the east at 15-20 knots; temperature 78 degrees F; visibility 7 miles; humidity 91 percent; and clouds broken at 2,500 feet, 10,000 feet and 25,000 feet. The 24-hour-delay forecast reveals slightly better conditions and a 40 percent chance of violation.

The STS-73 crew have remained at KSC since Sunday’s launch attempt. Today they are reviewing their flight plans.

NOTE: For additional details regarding STS-73 countdown milestones, please refer to KSC Release No. 99-95.
