On Launch Pad 39A at NASA's Kennedy Space Center in Florida, space shuttle Endeavour rises past the fixed service structure as it races toward space.

Endeavour began its final flight, the STS-134 mission to the International Space Station, at 8:56 a.m. EDT on May 16. Endeavour and its six-member crew will 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.
