At Launch Pad 39B, preparations for Wednesday's launch are under way. The launch countdown began on Sunday at 8 a.m. The pressurization of the orbital maneuvering system, the reaction control system and the main propulsion system is complete. The aft confidence test is complete. This test involves power-up and testing of all aft systems, such as the main propulsion system circuits. The power reactant storage and distribution system fuel loading is complete.
Weather officials are predicting favorable conditions for Wednesday's launch attempt, with a 20 percent chance of weather prohibiting the launch. Dryer conditions are expected to arrive on Wednesday, and the early launch time should avoid the afternoon thunderstorms. The primary concerns for launch are cumulus clouds within 10 nautical miles of the launch pad, and isolated showers within 20 nautical miles of the Shuttle Landing Facility.
