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.
