KENNEDY SPACE CENTER, FLA. -- European Space Agency astronaut Frank De Winne takes time out from driving practice of the M-113 armored personnel carrier to pose for a photo. De Winne is the backup for STS-122 Mission Specialist Leopold Eyharts will remain on the International Space Station as a flight engineer for Expedition 16 following the STS-122 mission. The practice near Launch Pad 39B is part of training on emergency egress procedures. An M-113 will be available to transport the crew to safety in the event of a contingency on the pad before their launch. 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

CAPE CANAVERAL, Fla. - STS-134 Pilot Greg H. Johnson takes time out from driving practice of the M113 armored personnel carrier to pose for a photo at NASA's Kennedy Space Center in Florida. An M113 is kept at the foot of the launch pad in case an emergency exit from the pad is needed and every shuttle crew is trained on driving the vehicle before launch. Space shuttle Endeavour's six crew members are at Kennedy for the launch countdown dress rehearsal called the Terminal Countdown Demonstration Test (TCDT) and related training. Targeted to launch April 19 at 7:48 p.m. EDT, they will deliver the Express Logistics Carrier-3, Alpha Magnetic Spectrometer-2 (AMS), a high-pressure gas tank, additional spare parts for the Dextre robotic helper and micrometeoroid debris shields to the space station. This will be the final spaceflight for Endeavour. For more information visit, www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Kim Shiflett
