LAUNCH - 1 DAY

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

VEHICLE: Columbia/OV-102
LOCATION: Pad 39B
TARGET LAUNCH DATE/TIME: Oct. 6 at 9:40 a.m. EDT
LAUNCH WINDOW: 2 hours, 30 minutes
TARGET KSC LANDING DATE/TIME: Oct. 22 at 7:35 a.m.
MISSION DURATION: 15 days, 21 hours, 55 minutes
CREW SIZE: 7
ORBITAL ALTITUDE and INCLINATION: 172 statute miles/39 degrees

NOTE: Following yesterday’s 24-hour launch delay, Columbia is now back on schedule for launch of mission STS-73 set for 9:40 a.m. on Friday, Oct. 6. Given an on time launch, Columbia is scheduled to land at KSC’s Shuttle Landing Facility at 7:35 a.m. Oct. 22.

Yesterday’s management decision to delay Columbia’s launch was due to expected high winds associated with Hurricane Opal affecting operations at KSC during the hours prior to tanking and through the launch window on Thursday.

At this time, the orbiter’s onboard cryogenic tanks are fully loaded with liquid hydrogen and liquid oxygen reactants and the mid-body umbilical unit has been retracted into the fixed service structure. Final mid-deck payload loading operations and spacelab experiment stowage operations are also complete.

Workers are now in the process of activating the orbiter’s inertial measurement units and making preparations to retract the rotating service structure from the vehicle at about 2 p.m. This move could be delayed by several hours without impacting the overall schedule if weather continues to threaten the area. Loading of the external tank with cryogenic propellants is scheduled to begin at about 1:20 a.m. tomorrow but could begin earlier if the vehicle is ready.

Air Force weather forecasters are indicating a 70 percent probability of weather prohibiting launch on Friday. This is due to the potential for gusting winds, rain and clouds associated with anticipated remnants of Hurricane Opal. There is a 10 percent probability of tanking criteria violation for a launch attempt on Friday.

During Friday’s launch window, the winds at Pad B are expected to be from the southwest at 15 - 20 knots; temperature 81 degrees F; visibility 7 miles; humidity 79 percent; and clouds broken at 2,500 feet, 10,000 feet and 25,000 feet. The 24-hour delay forecast reveals somewhat improved conditions and a 40 percent chance of violation.

The primary objective of mission STS-73 is to successfully perform the planned operations of the second U.S. Microgravity Laboratory. USML-2 experiments cover a variety of scientific disciplines including fluid physics, materials science, biotechnology and combustion science.
