Joe Dowdy, special operations manager at NASA's Kennedy Space Center, talks to a crowd of spectators gathered at the Banana Creek Viewing Site near the Saturn V Center at NASA's Kennedy Space Center in Florida to watch the launch of space shuttle Endeavour. The shuttle lifted off on its STS-134 mission to the International Space Station on time at 8:56 a.m. EDT on May 16.

The shuttle and its six-member crew are embarking on a mission to deliver the Alpha Magnetic Spectrometer-2 (AMS), Express Logistics Carrier-3, a high-pressure gas tank and additional spare parts for the Dextre robotic helper to the space station. Endeavour's first launch attempt on April 29 was scrubbed because of an issue associated with a faulty power distribution box called the aft load control assembly-2 (ALCA-2).
