With space shuttle Endeavour as the backdrop on Launch Pad 39 at NASA's Kennedy Space Center in Florida, the STS-126 crew members pose for a final photo after answering questions from the media. From left are Commander Chris Ferguson, Pilot Eric Boe and Mission Specialists Steve Bowen, Sandra Magnus, Shane Kimbrough, Donald Pettit and Heidemarie Stefanyshyn-Piper. The crew is at Kennedy to take part in the Terminal Countdown Demonstration Test, which includes equipment familiarization, emergency exit procedures and a simulated launch countdown. On the STS-126 mission, space shuttle Endeavour's crew will deliver equipment and supplies to the International Space Station in preparation for expansion from a three- to six-person resident crew aboard the complex. The mission also will include four spacewalks to service the station’s Solar Alpha Rotary Joints. Endeavour is targeted to launch Nov. 14. Photo credit: NASA/Kim Shiflett
