MISSION: STS-93 -- Chandra X-ray Observatory

VEHICLE: Columbia/OV-102
LOCATION: Launch Pad 39B
TARGET KSC LAUNCH DATE/TIME: July 20, 1999 at 12:36 a.m. EDT
TARGET KSC LANDING DATE/TIME: July 24, 1999 at 11:32 p.m. EDT

MISSION DURATION: 4 days, 23 hours
CREW: Collins, Ashby, Hawley, Coleman, Tognini
ORBITAL ALTITUDE and INCLINATION: 153 nautical miles/28.45 degrees
NOTE: The countdown for Space Shuttle Columbia's launch on mission STS-93 continues on schedule. Late stowage of the flight crew equipment into the orbiter's crew compartment concluded at about 12:30 a.m. today. Engineers completed payload inertial upper stage system checks at about 3 a.m. today and the Rotating Service Structure moved to the park position at about 7 a.m. At about 3:16 p.m. this afternoon, chilldown of the liquid propellant lines begins just prior to external tank loading. Columbia's external tank will be loaded with about 500,000 gallons of cryogenic propellant by about 6:46 p.m.

Weather forecasters indicate a 30 percent probability that weather could prohibit Tuesday's launch attempt. The primary concern is the chance of coastal showers. The launch time forecast calls for clouds to be scattered at 3,000 feet and 25,000 feet; visibility at 7 miles; winds out of the Southeast at 8 knots peaking to 12 knots; temperature at 80 degrees F and a chance of coastal showers. The 24-hour and 48-hour delay forecasts improve to 20 percent chance of weather violation.
