KENNEDY SPACE CENTER, FLA. -- The space shuttle Atlantis STS-122 crew poses for a group portrait at Launch Pad 39A as Atlantis undergoes final preparations for launch behind them. From left are Mission Specialists Hans Schlegel, Rex Walheim and Leland Melvin; Pilot Alan Poindexter; Commander Steve Frick; and Mission Specialists Stanley Love and Leopold Eyharts. Schlegel and Eyharts are with the European Space Agency. Eyharts will remain on the International Space Station as a flight engineer for Expedition 16 following the STS-122 mission. The STS-122 crew is at NASA's Kennedy Space Center to take part in terminal countdown demonstration test, or TCDT, activities, a standard part of launch preparations. The TCDT provides astronauts and ground crews with equipment familiarization, emergency egress training and a simulated launch countdown. On mission STS-122, Atlantis will deliver the European Space Agency's Columbus module to the International Space Station. Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, called Harmony, and will expand the research facilities aboard the station. Launch is targeted for Dec. 6. Photo credit: NASA/Kim Shiflett
