WASHINGTON: The date for the launch of NASA's space shuttle Endeavour has been finalised for May 16.
NASA managers have set the lift-off for 8:56 a.m. EDT on Monday. Launch attempts are available through May 26, except for May 21. The STS-134 mission to the International Space Station is the penultimate shuttle flight and the final one for Endeavour.
Space Shuttle Program Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach also discussed the progress of repairs since Endeavour's launch postponement on April 29 at a news briefing from NASA's Kennedy Space Center in Florida.
A short in the heater circuit associated with Endeavour's hydraulic system resulted in the launch postponement. 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. The heater circuits prevent freezing of the fuel lines providing hydraulic power to steer the vehicle during ascent and entry.
The faulty box was replaced May 4. Since Friday, Kennedy technicians installed and tested new wiring that bypasses the suspect electrical wiring and confirmed the heater system is working properly. They also are completing retests of other systems powered by the switchbox and are closing out Endeavour's aft compartment.
