The crew scheduled for launch aboard the Space Shuttle Columbia participates in the Terminal Countdown Demonstration Test.

The crew of the STS-87 mission, scheduled for launch Nov. 19 aboard the Space Shuttle Columbia from Pad 39B at Kennedy Space Center (KSC), participates in the Terminal Countdown Demonstration Test (TCDT) at KSC. Getting a look at the Space Shuttle Columbia are, from left, Commander Kevin Kregel; Pilot Steven Lindsey; Mission Specialist Kalpana Chawla, Ph.D.; Payload Specialist Leonid Kadenyuk of the National Space Agency of Ukraine (NSAU); Mission Specialist Takao Doi, Ph.D., of the National Space Development Agency of Japan; Kadenyuk’s back-up, Yaroslav Pustovyi, Ph.D., also of NSAU; and Mission Specialist Winston Scott. The TCDT is held at KSC prior to each Space Shuttle flight providing the crew of each mission opportunities to participate in simulated countdown activities. The TCDT ends with a mock launch countdown culminating in a simulated main engine cut-off. The crew also spends time undergoing emergency egress training exercises at the pad and has an opportunity to view and inspect the payloads in the orbiter's payload bay
