KENNEDY SPACE CENTER, FLA. -- During emergency egress from Launch Pad 39A, STS-120 Mission Specialists Stephanie Wilson (foreground) and Doug Wheelock settle in the slidewire basket. Wilson reaches for the release lever. The basket can carry them to a safe landing site below, if needed. The activity is part of the prelaunch terminal countdown demonstration test, or TCDT. The TCDT at NASA's Kennedy Space Center provides astronauts and ground crews an opportunity to participate in various launch preparation activities, including equipment familiarization and emergency training. The STS-120 mission will deliver the U.S. Node 2 module, named Harmony, aboard space shuttle Discovery to the International Space Station. Discovery is targeted to launch on its 14-day mission at 11:38 a.m. EDT on Oct. 23. Photo credit: NASA/Kim Shiflett KSC-07pd2801

KENNEDY SPACE CENTER, FLA. -- The STS-120 crew is at NASA's Kennedy Space Center for the pre-launch terminal countdown demonstration test, or TCDT. Here, during emergency egress training, crew members practice climbing into the slidewire baskets that can carry them safely to a landing site away from the shuttle. In the basket are, from left, Mission Specialists Doug Wheelock and Scott Parazynski and Pilot George Zamka. Watching them are, from left, Commander Pamela Melroy and Mission Specialists Stephanie Wilson and Daniel Tani, with camera. After the mission, Tani will remain aboard the International Space Station and return with the STS-122 crew, targeted to launch Dec. 6. The TCDT provides astronauts and ground crews an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. The STS-120 mission will deliver the U.S. Node 2 module, named Harmony, aboard space shuttle Discovery to the International Space Station.

KENNEDY SPACE CENTER, FLA. - Members of the crew for mission STS-121 look at the trailing umbilical system reel assembly that will be installed on the International Space Station during the mission. Seen here are Mission Specialists Stephanie Wilson and Lisa Nowak (background) and Michael Fossum (center front). The crew is taking part in a Crew Equipment Interface Test (CEIT) inside the Space Station Processing Facility at NASA's Kennedy Space Center. A CEIT provides hands-on experiences with equipment used on-orbit. Mission STS-121 is the second in the Return to Flight sequence and will carry on improvements that debuted during last year's STS-114 mission and build upon those tests. Launch is scheduled in July.

From left are Mission Specialists Stephanie Wilson and Scott Parazynski, Commander Pamela Melroy, Pilot George Zamka, and Mission Specialists Daniel Tani, Doug Wheelock and Paolo Nespoli, who represents the European Space Agency. After the mission, Tani will remain aboard the International Space Station and return with the STS-122 crew, targeted to launch Dec. 6. The TCDT provides astronauts and ground crews an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. The STS-120 mission will deliver the U.S. Node 2 module, named Harmony, aboard space shuttle Discovery to the International Space Station. Launch of Discovery on mission STS-120 is targeted for Oct. 23 at 11:38 a.m. EDT on a 14-day mission. Photo credit: NASA/Kim Shiflett KSC-07pd2737

CAPE CANAVERAL, Fla. - In Orbiter Processing Facility 3 at NASA's Kennedy Space Center in Florida, members of space shuttle Discovery's STS-131 crew participate in training activities during the Crew Equipment Interface Test, or CEIT, for their mission. Here, Mission Specialists Stephanie Wilson, left, and Clay Anderson get a close look at the exterior of Discovery. The CEIT provides the crew with hands-on training and observation of shuttle and flight hardware. The seven-member crew will deliver the multi-purpose logistics module Leonardo, filled with resupply stowage platforms and racks to be transferred to locations around the International Space Station. Three spacewalks will include work to attach a spare ammonia tank assembly to the station's exterior and return a European experiment from outside the station's Columbus module. Discovery's launch is targeted for March 18. For information on the STS-131 mission and crew, visit http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts131/index.html.
