Launch – 1 day: Launch countdown activities continue on schedule with no
problems begin reported. Operations to load the Power Reactant and Storage
Distribution system tanks with cryogenic reactants occurred on schedule
overnight and the orbiter mid-body umbilical unit has been demated and
retracted into the launch stricture.

At 9:30 p.m. tonight, the rotating service structure will be moved to the
launch position in preparation for tanking operations tomorrow. On Thursday
beginning at about 8:45 a.m., the external tank will be loaded with its
complement of 500,000 gallons of liquid cryogenic propellants. Tanking
efforts will last for about three hours.

The crew will be awakened for launch at 7:30 a.m. and be seated for
breakfast at 8 a.m. At 12 noon they will have lunch and at 1 p.m. they will
be given a final update on the launch time weather forecast. Following the
weather briefing they will don their launch suits and depart for the pad at
1:47 p.m. The hatch will be closed for flight at about 3:30 p.m.

Weather forecasters are currently indicating a 40 percent chance that
weather could prevent launch on Thursday. The primary concerns are for
showers and thunderstorms in the vicinity of the launch pad. At launch time
on Thursday, clouds will be scattered at 4000 feet, 10,000 feet and 25,000
feet. Winds will be from the southeast at 8 – 12 knots. Temperature will be
82 degrees, F. and humidity 74 percent. Forecasters call for a 70 percent
chance of violation for a 24-hour and 48-hour delay.
