During a pause in their prelaunch activities at the pad, the STS-121 crew talk to the media. They are standing in the landing area of the slidewire baskets. With the microphone is Mission Specialist Stephanie Wilson. The crew is at Kennedy 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 July 1 on mission STS-121. It will carry supplies to the International Space Station. Photo credit: NASA/Kim Shiflett
