Crew members inspect the orbital docking mechanism in the payload bay of Orbiter Endeavour during the Crew Equipment Interface Test.

STS-88 crew members inspect the orbital docking mechanism in the payload bay of Orbiter Endeavour during the Crew Equipment Interface Test (CEIT), held in the Orbiter Processing Facility Bay 1 at KSC. The CEIT gives astronauts an opportunity for a hands-on look at the payloads on which they will be working on orbit. STS-88 will be the first Space Shuttle launch for the International Space Station. Scheduled to lift off on Dec. 3, 1998, the seven-day mission will be highlighted by the mating of the U.S.-built Unity connecting module to the Zarya control module, which will already be in orbit, and two space walks to connect power and data transmission cables between the two modules
