Space Shuttle Atlantis and its seven-member STS-122 crew head toward the International Space Station. Liftoff from Kennedy Space Center's launch pad 39A occurred at 12:45 (EST). The launch was the third attempt for Atlantis since December 2007 to carry ESA's Columbus laboratory to the Station. During the 11-day mission, the crew's primary objective was to attach the laboratory to the Harmony module, adding to the station's size and capabilities. Onboard are astronauts Steve Frick, commander; Alan Poindexter, pilot; Leland Melvin, Rex Walheim, ESA's Hans Schlegel, Stanley Love and ESA's Leopold Eyharts, all mission specialists. Léopold joined Expedition 16 to serve as a flight engineer aboard the International Space Station.
