(06/23/1999) - STS-93 Mission Specialists Catherine G. Coleman (Ph.D.) and Steven A. Hawley (Ph.D.), and Commander Eileen M. Collins watch and listen to Bob Parks, a Safety Egress trainer with United Space Alliance, explaining the use of the slideware basket for emergency egress from the pad. Inside the basket are Pilot Jeffrey S. Ashby and Mission Specialist Michel Tognini of France, who represents the Centre National d'Etudes Spatiales (CNES). The STS-93 crew members are at KSC to participate in a Terminal Countdown Demonstration Test, which familiarizes them with the mission, provides training in emergency exit from the orbiter and launch pad, and includes a launch-day dress rehearsal culminating with a simulated main engine cut-off. The primary mission of STS-93 is the release of the Chandra X-ray Observatory, which will allow scientists from around the world to obtain unprecedented X-ray images of exotic environments in space to help understand the structure and evolution of the universe. The targeted launch date for STS-93 is no earlier than July 20 at 12:36 a.m. EDT from Launch Pad 39B
