KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT
WEDNESDAY, SEPTEMBER 27, 1995 (11:49 AM EDT)

LAUNCH - 1 DAY

MISSION: STS-73 -- U.S. MICROGRAVITY LABORATORY-2
VEHICLE: Columbia/OV-102
LOCATION: Pad 39B
LAUNCH DATE/TIME: Sept. 28 at 9:35 a.m. EDT
LAUNCH WINDOW: 2 hours, 30 minutes
KSC LANDING DATE/TIME: Oct. 14 at 7:30 a.m.
MISSION DURATION: 15 days, 21 hours, 55 minutes
ORBITAL ALTITUDE and INCLINATION: 172 statute miles/39 degrees

NOTE: The countdown for launch of Columbia continues on schedule with no technical issues being worked or problems reported from the pad. Liftoff remains set for 9:35 a.m. Thursday, Sept. 28, at the opening of the 2 1/2 hour window. Columbia is scheduled to land at KSC’s Shuttle Landing Facility at 7:30 a.m. Oct. 14.

Onboard cryogenics were loaded aboard Columbia yesterday and the orbiter’s mid-body umbilical unit was demated and retracted into the fixed service structure. Also, final spacelab experiment stowage operations were completed last night and the airlock was closed for flight.

Today, workers are 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 threatens the area. Loading of the external tank with cryogenic propellants is scheduled to begin at about 1:15 a.m. tomorrow but could begin earlier if the vehicle is ready.

A weak frontal boundary is stationary over north-central Florida and may produce scattered to broken clouds with a chance for offshore early morning showers. Forecasters are expected this system to remain north of KSC through tomorrow. Air Force weather forecasters are currently indicating a 30 percent probability of weather prohibiting launch on Thursday.

During Thursday’s launch window, the winds at Pad B are expected to be from the east at 5 -10 knots; temperature 81 degrees F; visibility 7 miles; humidity 79 percent; and clouds scattered at 2,500 and 10,000 feet and broken at 25,000 feet. The 24-hour-delay forecast reveals similar conditions and a 40 percent chance of violation.
