NASA managers have set the liftoff of space shuttle Endeavour for 8:56 a.m. EDT on Monday, May 16. 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 announced the date at a news briefing Monday from NASA's Kennedy Space Center in Florida. They also discussed the progress of repairs since Endeavour's launch postponement on April 29.
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. NASA Television will broadcast the crew's arrival live. The crew will deliver the Alpha Magnetic Spectrometer-2 (AMS) and critical supplies to the space station, including two communications antennas, a high-pressure gas tank and additional parts for the Dextre robot. AMS is a particle physics detector designed to search for various types of unusual matter. The crew also will transfer Endeavour's orbiter boom sensor system to the station, where it could assist spacewalkers as an extension for the station's robotic arm.
