During emergency egress training as part of the pre-launch terminal countdown demonstration test, or TCDT, STS-120 crew members practice getting out of the slidewire basket at the landing site. Jumping out is Mission Specialist Stephanie Wilson. Waiting his turn behind her is Mission Specialist Doug Wheelock. 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
