STS-134 Commander Mark Kelly and his five crewmates are set to arrive at Kennedy for prelaunch preparations on Thursday, May 12, at approximately 11 a.m. They also are completing retests of other systems powered by the switchbox and are closing out Endeavour’s aft compartment. Since Friday, Kennedy technicians installed and tested new wiring that bypasses the suspect electrical wiring and confirmed the heater system is working properly. The heater circuits prevent freezing of the fuel lines providing hydraulic power to steer the vehicle during ascent and entry. Technicians determined the most likely failure was inside a switchbox in the shuttle’s aft compartment and associated electrical wiring connecting the switchbox to the heaters. They also discussed the progress of repairs since Endeavour’s launch postponement on April 29.Ī short in the heater circuit associated with Endeavour’s hydraulic system resulted in the launch postponement. Space Shuttle Program Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach announced the date at a news briefing Monday from NASA’s Kennedy Space Center in Florida. The STS-134 mission to the International Space Station is the penultimate shuttle flight and the final one for Endeavour. Launch attempts are available through May 26, except for May 21. NASA managers have set the liftoff of space shuttle Endeavour for 8:56 a.m.
