Space Shuttle Endeavour On Its Way

1 The space shuttle Endeavour STS-134 sits on launch pad 39A after the rollback of the Rotating
Service Structure at the Kennedy Space Center in Cape Canaveral, Florida May 15, 2011. Endeavour
and its six-man crew will deliver a unique astronomical and particle physics experiment to the
International Space Station. The $2 billion Alpha Magnetic Spectrometer is designed to illuminate
dark matter and other exotic forms of nature that so far have eluded scientists' grasp.
