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), participate in the Terminal Countdown Demonstration Test (TCDT) at KSC. Posing for a group shot by Pad 39B are, from left to right, Mission Specialist Kalpana Chawla, Ph.D.; Mission Specialist Winston Scott; Mission Specialist Takao Doi, Ph.D., of the National Space Development Agency of Japan; Commander Kevin Kregel; Payload Specialist Leonid Kadenyuk of the National Space Agency of Ukraine (NSAU); Pilot Steven Lindsey; and Kadenyuk’s back-up, Yaroslav Pustovyi, Ph.D., also of NSAU. 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 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 KSC-97PC1620

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
