The STS-121 crew, including ESA astronaut Thomas Reiter, are instructed in the use of the slidewire basket at Launch Pad 39B. The crew is at NASA's Kennedy Space Center, in Florida, for Terminal Countdown Demonstration Test activities. Over several days, the crew will practice emergency egress from the pad and suit up in their orange flight suits for the simulated countdown to launch. Space Shuttle Discovery is designated to launch on the STS-121 mission to the ISS in July.
