KENNEDY SPACE CENTER, FLA. - After rollback of the Rotating Service Structure, Space Shuttle Endeavour is bathed in light. Seen above the orange external tank behind Endeavour is the "beanie cap," or vent hood assembly at the end of the gaseous oxygen vent arm. The orbiter access arm extends to the cockpit area of Endeavour. At the end of the arm is the White Room, , an environmental chamber that provides crew access into the orbiter. STS-111 is the second Utilization Flight to the International Space Station, carrying the Multi-Purpose Logistics Module Leonardo, the Mobile Base System (MBS), and a replacement wrist/roll joint for the Canadarm 2. Also onboard Space Shuttle Endeavour is the Expedition 5 crew who will replace Expedition 4 on board the Station. The MBS will be installed on the Mobile Transporter to complete the Canadian Mobile Servicing System, or MSS. The mechanical arm will then have the capability to "inchworm" from the U.S. Lab Destiny to the MSS and travel along the truss to work sites. Expedition 4 crew members will return to Earth with the STS-111 crew on Endeavour. Launch is scheduled at 7:44 p.m. EDT, May 30, 2002
