CAPE CANAVERAL, Fla. -- Space shuttle Endeavour's six STS-134 astronauts, dressed in their orange launch-and-entry suits, wave to news media and other spectators as they walk toward the Astrovan parked in front of the Operations and Checkout Building at NASA's Kennedy Space Center in Florida. The modified Airstream recreational vehicle has transported astronauts to their spacecraft since 1984. Leading the way are Commander Mark Kelly, right, and Pilot Greg H. Johnson. Behind Kelly are crewmates Michael Fincke and Andrew Feustel. Behind Johnson are crewmates Roberto Vittori with the European Space Agency and Greg Chamitoff. STS-134 will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank and additional spare parts for the Dextre robotic helper to the space station. Endeavour was scheduled to launch at 3:47 p.m. on April 29, but that attempt was scrubbed for at least 72 hours while engineers assess an issue associated with the shuttle's Auxiliary Power Unit 1. STS-134 will be the final spaceflight for Endeavour. For more information visit, www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Kim Shiflett
