KENNEDY SPACE CENTER, FLA. - Workers in the Vertical Processing Facility check the position of the Hubble Space Telescope's replacement Reaction Wheel Actuator on the Large Orbital Protective Enclosure (LOPE), which is contained in the Multi-Use Lightweight Equipment (MULE) for flight. Part of Hubble's Pointing Control System, the actuators receiving information from sensors and physically adjust Hubble's position and orientation so that Hubble can view the required celestial bodies. The reaction wheels work by rotating a large flywheel up to 3000 rpm or braking it to exchange momentum with the spacecraft which will make Hubble turn. The RWA is part of the payload on mission STS-109, the Hubble Servicing Mission, scheduled to launch Feb. 28, 2002 KSC-02pd0097

KENNEDY SPACE CENTER, FLA. -- The STS-111 crew looks at the replacement pitch roll joint for the SSRMS (Canadarm 2) they will be installing on the mission to the International Space Station. The crew comprises Commander Kenneth Cockrell, Pilot Paul Lockhart, and Mission Specialists Franklin Chang-Diaz and Phillippe Perrin, who is with the French Space Agency. Part of the payload on mission STS-111 is the Mobile Base System (MBS), which 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. STS-111 is the second utilization flight (UF-2) to the Space Station and will also carry the Expedition 5 crew to replace Expedition 4. Launch is scheduled for May 30, 2002 KSC-02pd0555

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.
