KENNEDY SPACE CENTER, FLA. -- Members of the STS-122 crew receive a briefing inside an M-113 armored personnel carrier near Launch Pad 39B. An M-113 will be available to transport the crew to safety in the event of an emergency on the pad before their launch. Seated on the bench at left is European Space Agency astronaut Frank De Winne, the backup for STS-122 Mission Specialist Leopold Eyharts. Seated on the bench at right, from back to front are Commander Steve Frick; Mission Specialists Rex Walheim, Hans Schlegel of the European Space Agency, and Leland Melvin; and Pilot Alan Poindexter. The crew is participating in Terminal Countdown Demonstration Test 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
