KENNEDY SPACE CENTER, FLA. -- Space shuttle Atlantis STS-122 Mission Specialist Stanley Love takes part in a press conference at the slidewire basket landing on Launch Pad 39A. 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
