KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT

LAUNCH - 1 DAY
MISSION: STS-73 -- U.S. MICROGRAVITY LABORATORY-2
LOCATION: Pad 39B
TARGET LAUNCH DATE/TIME: Oct. 15 at 9:46 a.m. EDT
LAUNCH WINDOW: 2 hours, 30 minutes
TARGET KSC LANDING DATE/TIME: Oct. 31 at 6:41 a.m. (EST)
MISSION DURATION: 15 days, 21 hours, 55 minutes
CREW SIZE: 7
ORBITAL ALTITUDE and INCLINATION: 172 statute miles/39 degrees
NOTE: The countdown for launch of Columbia continues on schedule today following yesterday’s 24-hour postponement for additional checks required on Columbia’s three Space Shuttle main engines. Launch is set for Sunday, Oct. 15 at 9:46 a.m.
Technicians have completed the ultrasound checks on the three engine’s high pressure oxidizer turbo pump discharge ducts and engineers have cleared the engines for launch. Also, the no. 1 general purpose computer on Columbia’s flight deck that exhibited signs of problems during normal prelaunch testing has been replaced and successfully tested.
At this time, final vehicle and facility close-outs are continuing. Final mid-deck payload loading operations are also underway.
The rotating service structure will be retracted to launch position at about 4 p.m. today, pending weather. Loading of the external tank with cryogenic propellants is scheduled to begin at about 1:26 a.m. Sunday.
Air Force weather forecasters are currently indicating an 80 percent probability of weather prohibiting launch on Sunday. An upper level disturbance, centered south of the Florida Keys, may produce extensive cloudiness and showers. Also, a cold front is moving westward and will likely influence KSC’s weather during the launch window on Sunday. There is a 20 percent chance of weather violating tanking constraints during tanking operations overnight.
During Sunday’s launch window, the winds at Pad 39B are expected to be from the west (gradually shifting to come from the north) at 12-18 knots; temperature 83 degrees F; visibility 7 miles; humidity 68 percent; and clouds scattered to broken at 2,500 feet and broken at 4,000 feet and 10,000 feet.
NOTE: For additional details regarding STS-73 countdown milestones, please refer to KSC Release No. 99-95.
