(03/09/2002) -- In the Orbiter Processing Facility, STS-111 Pilot Paul Lockhart inspects the window of Endeavour's cockpit. He and other crew members are taking part in a Crew Equipment Interface Test in preparation for launch. Mission STS-111 will carry to the International Space Station the Multipurpose Logistics Module (MPLM), filled with experiment racks and three stowage and resupply racks, and the Mobile Base System (MBS), which will attach to the Mobile Transporter and complete the Canadian Mobile Servicing System, or MSS. The Station's mechanical arm will then have the capability to 'inchworm' from the U.S. Lab to the MSS and travel along the truss to work sites on the Station. Launch of Endeavour on mission STS-111 is scheduled for May 30, 2002
