LAUNCH MINUS 2 DAYS

MISSION: STS-70 -- TDRS-G

VEHICLE: Discovery/OV-103
LOCATION: Pad 39-B
LAUNCH DATE/TIME: July 13 at 9:41 a.m.
LAUNCH WINDOW: 2 hours, 30 minutes
KSC LANDING DATE/TIME: July 21 at 7:51 a.m.
MISSION DURATION: 7 days, 22 hours
CREW SIZE: 5
ORBITAL ALTITUDE and INCLINATION: 184 statute miles/28.45 degrees

NOTE: The countdown for launch of Discovery began at 10 a.m. yesterday for a 2 1/2 hour launch window opening at 9:41 a.m. on Thursday, July 13. TDRS deployment is scheduled to occur at about 3:53 p.m. Thursday. Discovery is scheduled to land at KSC’s Shuttle Landing Facility at 7:51 a.m. July 21.

At this time, Pad 39-B has been cleared for loading the onboard cryogenic tanks with the liquid hydrogen and liquid oxygen reactants. Reactant loading is expected to be finished at about 1 p.m. The reactants will provide electricity for the orbiter and crew while in space and drinking water as a by-product during their 8-day mission.

After the cryogenics are loaded, the orbiter’s mid-body umbilical unit will be demated and retracted into the fixed service structure. Final vehicle and facility close-outs will also resume. Final mid-deck payload loading operations will finish tomorrow.

On Wednesday, preparations will be made to retract the rotating service structure to launch position at about 5:30 p.m. Loading of the external tank with cryogenic propellants is scheduled to begin at about 1:21 a.m. Thursday.

Air Force weather forecasters are currently indicating a 40 percent probability of weather prohibiting launch on Thursday. The primary concerns are for thick layered clouds associated with showers and thunderstorms. During Thursday’s launch window, the winds at Pad B are expected to be from the east at 7-12 knots; temperature 83 degrees F; visibility 7 miles; humidity 72 percent; and clouds scattered at 3,000 and 10,000 feet, and broken at 30,000 feet. The 24-hour-delay forecast reveals similar conditions and a 40 percent chance of violation.

The five-member astronaut crew was scheduled to arrive at KSC’s Shuttle Landing Facility late last night but were diverted to Orlando International Airport at about 6:30 p.m. due to heavy rains and lightning at KSC. The crew was driven from Orlando to their KSC crew quarters, arriving about 8 p.m. yesterday. Today they will be involved with checking out their mission plans and fit checks of their equipment.
