At NASA’s Kennedy Space Center in Florida, the STS-133 crew takes a break from a simulated launch countdown to ham it up 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 simulation was part of a week-long Terminal Countdown Demonstration Test. 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.
