KSC SHUTTLE STATUS REPORT - FRIDAY, FEB. 1, 1991 STS-39/DoD - DISCOVERY (OV 103) - OPF BAY 1 LAUNCH - MARCH 1991 WORK IN PROGRESS: - Replacement of a third thruster on the right orbital maneuver- ing system pod. The bay is opened for limited access today and will be reopened for normal work tomorrow. - Pressurization of the main landing gear struts. - Thermal protection system operations. - As part of the troubleshooting of the waste water dump system problem experienced on STS-35, technicians removed and replaced the filter package on Discovery. The three polyurethane filters in the package removed from Discovery were found to be in various states of degradation. The degradation appears to be natural deterioration due to age. The filter package currently installed in Discovery is new and there are no concerns about its perfor- mance. WORK COMPLETED: - Replacement of two thrusters on the left orbital maneuvering system pod. WORK SCHEDULED: - Structural leak checks of the orbital maneuvering system pods this weekend. - Structural leak checks of the orbiter next week. - Weight and center of gravity checks.
