Shuttle Processing Note: Preparations are on schedule to launch Shuttle Atlantis at about 4:15 p.m. on Monday. Today, the seven-member flight crew arrived at KSC’s Shuttle Landing Facility (SLF) at 3:30 p.m. Over the next few days, the crew will review flight procedures and take opportunities to fly in training jets from the SLF.

At the launch pad, external tank purge activities are complete and orbiter aft compartment close-outs conclude this afternoon. Launch controllers will begin the countdown at the T-43 hour mark at 7 p.m. today.

Weather forecasters indicate a 70 percent chance of favorable weather on launch day. The forecast calls for scattered clouds at 4,000 – 7,000 feet and broken clouds at 25,000 – 31,000 feet; visibility at 7 miles; winds out of the east at 10 gusting to 15 knots; temperature at 77 degrees F and relative humidity at 45 percent. The primary concern is the potential for thunderstorm anvil clouds.
