CAPE CANAVERAL, Fla. – Dressed in their launch-and-entry suits, the STS-126 crew members eagerly exit the Operations and Checkout Building at NASA's Kennedy Space Center in Florida. They will head to Launch Pad 39A for a simulated countdown in space shuttle Endeavour. Clockwise from left are Pilot Eric Boe, Mission Specialists Steve Bowen, Shane Kimbrough, Sandra Magnus, Heidemarie Stefanyshyn-Piper and Donald Pettit, and Commander Chris Ferguson. The crew is at Kennedy to take part in the Terminal Countdown Demonstration Test, which includes equipment familiarization, emergency exit training and the simulated 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 KSC-08pd3425
