STS-96 -- 2nd U.S. INTERNATIONAL SPACE STATION FLIGHTNOTE: Following Discovery's recent orbital maneuvering system thruster replacements, workers completed manifold draining and backfilling efforts over the weekend. Troubleshooting of a minor leak on APU No. 2 is under way. Installation of the androgynous peripheral docking system (APDS) begins today. This week, technicians will resume efforts to install the integrated vehicle health monitoring system on the orbiter's main propulsion system.
STS-96 SCHEDULED OPERATIONAL MILESTONES (dates are target only):
STS-93 -- Chandra X-ray Observatory (formerly AXAF)
NOTE: Technicians have completed Columbia's processing efforts to date and are preparing to transport the orbiter to the Vehicle Assembly Building on Wednesday. Columbia will reside in VAB high bay 2 in temporary storage until mid-April, when Shuttle Discovery rolls out of OPF bay 1. Columbia will then be transferred to OPF bay 1 to complete STS-93 orbiter preparations.
STS-99 -- SHUTTLE RADAR TOPOGRAPHY MISSION (SRTM)NOTE: Removal of Endeavour's tunnel adapter forward extension is complete. Water spray boiler No. 3 installation is also complete. Workers are servicing freon coolant loop No. 1 today and efforts are under way to upgrade the main propulsion system's 17-inch disconnect valve actuator. Tunnel adapter removal is also scheduled this week.
STS-101 -- 3rd INTERNATIONAL SPACE STATION FLIGHTNOTE: Atlantis is being moved to the VAB transfer aisle today to allow room for Shuttle Columbia's shift into VAB high bay 2. Atlantis will remain in the transfer aisle while preparations are made for its arrival in OPF bay 3 on Feb. 17. A majority of the orbiter's tactical air and navigation system (TACAN) modification is complete. Only 2 weeks of TACAN work remains. Workers also completed about half of the required orbiter leak checks while in the VAB.
