STS-88 Mission Commander Robert D. Cabana (left) and Pilot Frederick W. “Rick” Sturckow (right) take their seats in the flight deck inside space shuttle Endeavour during Terminal Countdown Demonstration Activities, or TCDT. The TCDT includes mission familiarization activities, emergency egress training, and the simulated main engine cut-off exercise.
Mission STS-88 was the first U.S. flight for the assembly of the International Space Station and carried the Unity connecting module. Unity was mated with the already orbiting Russian-built Zarya control module. The mission included three spacewalks to connect power, data and utility lines and install exterior equipment.
