(11/15/1999) --- STS-103 Mission Specialist Jean-François Clervoy of France, who is with the European Space Agency, practices driving a small armored personnel carrier that is part of emergency egress training during Terminal Countdown Demonstration Test (TCDT) activities. Riding on the front is Capt. George Hoggard, trainer with the KSC Fire Department. Behind him is Pilot Scott J. Kelly; at right (with earphones) is Mission Specialist Claude Nicollier of Switzerland, who is with the European Space Agency, and at the rear Mission Specialist Steven L. Smith. The tracked vehicle could be used by the crew in the event of an emergency at the pad during which the crew must make a quick exit from the area. The TCDT also provides simulated countdown exercises and opportunities to inspect the mission payloads in the orbiter's payload bay. STS-103 is a 'call-up' mission due to the need to replace and repair portions of the Hubble Space Telescope. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The other STS-103 crew members are Commander Curtis L. Brown Jr. and Mission Specialists C. Michael Foale (Ph.D.) and John M. Grunsfeld (Ph.D.). The mission is targeted for launch Dec. 6 at 2:37 a.m. EST
