(04/10/1998) --- STS-91 crew members participate in the Crew Equipment Interface Test, or CEIT, in KSC's Orbiter Processing Facility Bay 2. Laying down inspecting a foot restraint for an extravehicular activity (EVA) spacewalk is STS-91 Mission Specialist Franklin Chang-Diaz, Ph.D. Looking over his shoulder is Kieth Johnson, an EVA trainer and flight controller from Johnson Space Center. STS-91 Mission Specialist Janet Kavandi, Ph.D., stands next to Johnson. During CEIT, the crew have an opportunity to get a hands-on look at the payloads with which they'll be working on-orbit. The STS-91 crew are scheduled to launch aboard the Shuttle Discovery for the ninth and final docking with the Russian Space Station Mir from KSC's Launch Pad 39A on May 28 at 8:05 EDT
