Space shuttle Atlantis passes the fixed service structure as it races toward the sky on mission STS-122.

Trailing fire from its engines and solid rocket boosters, space shuttle Atlantis passes the fixed service structure as it races toward the sky on mission STS-122. Liftoff was on time at 2:45 p.m. EST. This is the third launch 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.
