CAPE CANAVERAL, Fla. -- During a simulated launch countdown on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-133 Mission Specialists Nicole Stott, left, and Michael Barratt are strapped into their seats on space shuttle Discovery. Next, they will practice escaping the shuttle, in preparation for an unlikely emergency at the pad on launch day. The simulated launch countdown and emergency exit training are part of a week-long Terminal Countdown Demonstration Test (TCDT). Discovery and its STS-133 crew will deliver the Permanent Multipurpose Module, packed with supplies and critical spare parts, as well as Robonaut 2, the dexterous humanoid astronaut helper, to the International Space Station. Launch is targeted for Nov. 1 at 4:40 p.m. For more information on the STS-133 mission, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts133/. Photo credit: NASA/Kim Shiflett
