CAPE CANAVERAL, Fla. -- In the first light of day, space shuttle Endeavour stands ready for processing at Launch Pad 39A 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 the Vehicle Assembly Building at 7:56 p.m. EST March 10 and ended at 3:49 a.m. EST, nearly eight hours later. This is Endeavour's final scheduled rollout. 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/Jack Pfaller
