(01/09/1998) --- STS-89 Mission Specialist Salizhan Sharipov of the Russian Space Agency drives the M-113 armored personnel carrier as part of Terminal Countdown Demonstration Test (TCDT) activities while George Hoggard, a training officer with KSC Fire Services, gets a free ride. The TCDT is held at KSC prior to each Space Shuttle flight to provide crews with an opportunity to participate in simulated countdown activities. The STS-89 mission will be the eighth docking of the Space Shuttle with the Russian Space Station Mir. After docking, STS-89 Mission Specialist Andrew Thomas, Ph.D., will transfer to the space station, succeeding David Wolf, M.D., who will return to Earth aboard Endeavour. Dr. Thomas will live and work on Mir until June. STS-89 is scheduled for a Jan. 22 liftoff at 9:48 p.m
