CAPE CANAVERAL, Fla. -- At Launch Pad 39A at NASA's Kennedy Space Center in Florida, members of the STS-133 crew receive instruction in the pad's bunker as part of the Terminal Countdown Demonstration Test (TCDT) emergency exit training. From left are Commander Steve Lindsey, Mission Specialists Nicole Stott, Michael Barratt and Alvin Drew, Pilot Eric Boe, and Mission Specialist Tim Kopra. TCDT provides each shuttle crew and launch team an opportunity to participate in various simulated activities, including equipment familiarization and a launch countdown. Space shuttle 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
