Steve Lindsey and Pilot Eric Boe return their Shuttle Training Aircraft STA to the Shuttle Landing Facility runway.

STS-133 Commander Steve Lindsey and Pilot Eric Boe return their Shuttle Training Aircraft (STA) to the Shuttle Landing Facility runway at NASA's Kennedy Space Center in Florida. They flew the modified Gulfstream II business jets to mimic the shuttle's handling during the final phase of landing. Practice landings are part of the Terminal Countdown Demonstration Test (TCDT), which provides each shuttle crew and launch team an opportunity to participate in various simulated activities, including equipment familiarization and emergency training at the launch pad.

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/Jack Pfaller
