The STS-122 crew members greet onlookers as they head for the Astrovan and their ride to Launch Pad 39A for the launch of space shuttle Atlantis on the STS-122 mission. From left are Mission Specialists Leland Melvin, Stanley Love and Leopold Eyharts, Pilot Alan Poindexter, Mission Specialists Hans Schlegel and Rex Walheim, and Commander Steve Frick. The launch will be the third attempt for Atlantis since December 2007 to carry the European Space Agency's Columbus laboratory to the International Space Station. During the 11-day mission, the crew's prime objective is to attach the laboratory to the Harmony module, adding to the station's size and capabilities. Photo credit: NASA/Kim Shiflett
