At NASA's Kennedy Space Center in Florida, the STS-133 crew takes a break from a simulated launch countdown and simulated pad emergency to take a group photo on the 195-foot level of Launch Pad 39A. From left are, Pilot Eric Boe, Mission Specialist Michael Barratt, Commander Steve Lindsey, and Mission Specialists Tim Kopra, Nicole Stott, and Alvin Drew. The simulations 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
