During a simulated pad emergency on Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-133 Mission Specialists Tim Kopra, left, and Alvin Drew hop in a slidewire basket that would take them to a safe bunker below the pad in an unlikely emergency situation. The emergency training while aboard space shuttle Discovery is 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
