Shuttle Endeavour Launch Status

April 19, 2001 2:41 p.m. EDT. Launch occured ontime at the opening of a 4.5 minute launch window. SSME cutoff ontime at T+8 minutes 39 seconds. Shuttle liftoff weight 4,521,931 lbs.

On Tuesday, April 17, 2001, engineers completed troubleshooting a faulty lighting dimmer switch on the flight deck of the crew module. The electrical box was successfully replaced overnight following cryogenic loading. Loading of the orbiter's onboard cryogenic storage tanks is now complete, and technicians are working no further problems at the pad at this time. (Reference KSC Shuttle Status 4/18/2001)
On Monday, April 16, 2001, the launch countdown for mission STS-100 began at 6 p.m. as scheduled. Preparation continues toward a launch of Space Shuttle Endeavour and the seven-member flight crew at 2:41 p.m. Thursday. The orbiter's onboard cryogenic storage tanks were then loaded for flight and the orbiter midbody umbilical unit demated. Loading operations began about one hour late, allowing engineers to troubleshoot a lighting dimmer switch in the crew module before clearing the pad. (Reference KSC Shuttle Status 4/17/2001)

Space Shuttle Endeavour rolled out of the Vehicle Assembly Building today at about 9:50 a.m. Solid rocket booster closeout inspections slightly delayed first motion, and Endeavour is now expected to arrive at the pad before 4 p.m. Once at the pad, routine launch pad validations commence, verifying all vehicle and facility interfaces.
