CAPE CANAVERAL, Fla. - On Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-126 Mission Specialist Heidemarie Stefanyshyn-Piper (far right) answers a question from the media. The other crew members with her are (from left) Commander Chris Ferguson, Pilot Eric Boe and Mission Specialists Steve Bowen, Sandra Magnus, Shane Kimbrough and Donald Pettit. 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
