CAPE CANAVERAL, Fla. -- Bathed in xenon lights, space shuttle Endeavour moves along the crawlerway from the Vehicle Assembly Building to Launch Pad 39A, illuminated in the background, at NASA's Kennedy Space Center in Florida. Riding atop a crawler-transporter attached to its external fuel tank and solid rocket boosters, Endeavour's 3.4-mile trek, known as "rollout," began at 7:56 p.m. EST and will take about seven hours to complete. This is the final scheduled rollout for Endeavour. Endeavour and its six-member crew will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank, additional spare parts for the Dextre robotic helper and micrometeoroid debris shields to the International Space Station on the shuttle's final spaceflight, STS-134. Launch is targeted for 7:48 p.m. EDT April 19. For more information, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Frankie Martin
