(05/30/2002) -- After rollback of the Rotating Service Structure in the early morning hours, Space Shuttle Endeavour sits bathed in light on its Mobile Launcher Platform on Launch Pad 39A. Seen extending to the cockpit area of Endeavour is the orbiter access arm. At the end of the arm is the White Room, an environmental chamber. Below, on either side of Endeavour's tail, are the tail service masts that support fluid, gas and electrical requirements of the orbiter's liquid oxygen and liquid hydrogen aft T-0 umbilicals. 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 for 7:44 p.m. EDT, May 30, 2002
