Mission Specialist Hans Schlegel dons his helmet for launch of space shuttle Atlantis on the STS-122 mission. Schlegel represents the European Space Agency. The launch, scheduled for 2:45 p.m. EST, 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
