Bathed in xenon lights space shuttle Endeavour is on a nighttime journey from the Vehicle Assembly Building.

Bathed in xenon lights, space shuttle Endeavour, attached to its external fuel tank and solid rocket boosters, is on a nighttime journey from the Vehicle Assembly Building to Launch Pad 39A at NASA's Kennedy Space Center in Florida. The 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, which is attached to its external fuel tank and solid rocket boosters atop a crawler-transporter.

Endeavour and its six STS-134 crew members 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. Launch is targeted for April 19 at 7:48 p.m. EDT. For more information visit, www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Jim Grossmann
