Shuttle Processing Note: Over the weekend, mission managers determined that one of the two valves in the Auxiliary Power Unit’s coolant system (water spray boiler No. 3) could be replaced at the Pad without impacting the scheduled launch of Endeavour on May 30. Although this work had never been attempted before with a Shuttle at the Pad, technicians from vendor Hamilton Sundstrand were successful in replacing the valve. Functional tests of the new valve were completed Sunday, followed by 24-hour leak checks. Closeouts of the aft engine compartment were completed as the launch countdown picked up on schedule last night.

The STS-111 crew arrived at the Shuttle Landing Facility yesterday in preparation for their scheduled launch to the International Space Station this Thursday.

The weather forecast shows a 60 percent chance of weather prohibiting launch on Thursday due to possible thunderstorms in the vicinity. The forecast for a 24-hour and 48-hour scrub turnaround both indicate a 70 percent chance of weather prohibiting launch.
