STS-96 -- 2nd U.S. INTERNATIONAL SPACE STATION FLIGHTNOTE: Shuttle managers are now targeting May 20 for the launch of Shuttle Discovery on mission STS-96. That date on the Eastern Range became available after Delta FUSE managers announced a slip in their launch date. Shuttle processing managers at KSC have been protecting a May 20 launch option and are ready to support.
Discovery's Ku band system interface testing is complete. Auxiliary power unit lubrication servicing is under way today and checks of the integrated vehicle health monitoring system continue. Orbiter aft and midbody compartment close-outs proceed on schedule. External tank and solid rocket booster close-outs continue in the Vehicle Assembly Building and workers have completed thermal foam venting on the external tank.
STS-96 SCHEDULED OPERATIONAL MILESTONES (dates are target only):
STS-93 -- Chandra X-ray Observatory (formerly AXAF)
NOTE: Columbia is jacked and leveled in Vehicle Assembly Building high bay 2 undergoing system observation during a temporary storage period. Columbia will remain in the VAB until April 14, when Shuttle Discovery rolls out of Orbiter Processing Facility bay 1. Columbia will then be transferred to OPF bay 1 to complete STS-93's orbiter prelaunch preparations.
STS-99 -- SHUTTLE RADAR TOPOGRAPHY MISSION (SRTM)NOTE: Removal of Endeavour's left orbital maneuvering system (OMS) engine is complete. Fuel cells No. 1 and No. 2 have been replaced. Leak checks on freon coolant loop No. 1 revealed an alternate power converter unit leak and technicians are currently troubleshooting the issue. Preparations are now in work for next week's removal of the right hand OMS pod.
STS-101 -- 3rd INTERNATIONAL SPACE STATION FLIGHTNOTE: Atlantis' external airlock has been removed to provide workers additional access to the orbiter's midbody. Main propulsion system leak and functional tests continue. Replacement of the strut and attach bolt for the power reactant storage and distribution system oxygen tanks is ongoing.
