As part of the Crew Equipment Interface Test (CEIT), Boeing Structural Engineer Karry Switzer (second from left) shows part of the Unity connecting module to STS-88 crew members Mission Specialist Jerry L. Ross and Pilot Rick W. Sturckow in the Space Station Processing Facility at KSC. The Unity connecting module, part of the International Space Station, will be mated to the Zarya control module, which will already be in orbit. The CEIT gives astronauts an opportunity for a hands-on look at the payloads on which they will be working while on orbit. STS-88 will be the first Space Shuttle launch for the International Space Station. Launch is scheduled for December 1998
