LAUNCH WINDOW: 2 hours, 30 minutes
KSC LANDING DATE/TIME: Sept. 18 at 7:38 a.m.

The countdown for launch of Endeavour continues on schedule today. The 2 1/2 hour launch window opens at 11:09 a.m. Thursday, Sept. 7. Completing an 11-day mission, Endeavour is scheduled to land at 7:38 a.m. Sept. 18 at KSC.

Fuel cell no. 2 that was replaced over the weekend has been retested and is working properly. No further technical issues are being worked by the Shuttle Mission Management Team and no problems are being reported from the pad. Overnight, discussions were held to possibly delay the deployment of the solid rocket booster recovery ships due to high sea states. At today’s mission management team meeting, it was decided the ships should be deployed on schedule. They departed Hangar AF at about 11 a.m. today. 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 later this afternoon. 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 2:49 a.m. tomorrow but could begin up to a half hour earlier if the vehicle is ready.

Air Force weather forecasters are now indicating a 60 percent probability of weather prohibiting launch on Thursday. The primary concerns are for showers and thunderstorms. During Thursday’s launch window, the winds at Pad A are expected to be from the northeast at 7 -10 knots; temperature 83 degrees F; visibility 7 miles; humidity 77 percent; and clouds scattered at 2,500 and 10,000 and broken at 25,000 feet. The 24-hour-delay forecast reveals slightly better conditions and a 40 percent chance of violation. Also, there is a 10 percent chance of lightning violating tanking constraints early Thursday morning.

Today, the five-member astronaut crew will be briefed on tomorrow’s launch weather outlook at KSC and the TAL sites in Spain and Africa. Also today, the crew will receive a final mission briefing and make last minute adjustments to their flight plans while completing their review of launch day activities.
