KENNEDY SPACE CENTER, FLA. -- STS-120 Mission Specialist Scott Parazynski arrives on Launch Pad 39A to start a simulated launch countdown, culmination of the prelaunch terminal countdown demonstration test, or TCDT. His name patch reflects the nicknames the crew gave each other for the event. 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/George Shelton
