STS-39/DoD - DISCOVERY (OV 103) - OPF BAY 1
LAUNCH - MARCH 1991
WORK IN PROGRESS:
- Preparations to replace three thrusters on orbital maneuvering
system pods.
- Main propulsion system gaseous oxygen system leak checks.
- Cleaning of the payload bay.
- Closeouts of the aft compartment.
- External tank door functional test.
WORK COMPLETED:
- Leak tests of two orbital maneuvering system thrusters and weld
checks of a third thruster.
- Water spray boiler steam vent nozzle replaced.
- Check out of the flipper doors.
WORK SCHEDULED:
- Installation of three OMS thrusters on Thursday.
- Structural leak checks of the orbiter in the next few days.
- Final payload bay door closure tomorrow.
- Closeouts to prepare for rollover to the Vehicle Assembly
Building next week.
CONCERNS:
- Two thrusters on the left pod will be replaced because of out
of specification leakage. One thruster on the right pod will be
replaced because of suspect nozzle to body welds. New thrusters
are being checked today at the Hypergolic Maintenance Facility.
Rollover to the VAB is now targeted for Feb. 7.

- Auxiliary power unit functional tests.
- Preparations to install the forward reaction control system.
- Flutter buffet instrumentation installation.
- Potable water servicing.
- Functional test of the waste containment system.
- Ku-band antenna testing.
WORK COMPLETED:
- Main engine flight readiness test on main engines 1 and 3. En-
gine 2's controller backup channel halted during power up. Test
could not be run on engine 2 and controller replacement is re-
quired.
WORK SCHEDULED:
- Replacement of the main engine 2 controller and subsequent
flight readiness test of that engine.

- Modification to beef up the lithium hydroxide canister door in
the middeck.
- Thermal protection system operations.
WORK SCHEDULED:
- Closeouts to ready the vehicle for transfer to the Orbiter
Processing Facility following Discovery's move to the VAB.
STS-37 SOLID ROCKET BOOSTERS/EXTERNAL TANK - VAB
WORK IN PROGRESS:
- Closeouts of all booster field joints and cable routing.
WORK SCHEDULED:
- Alignment of the boosters.
- Mate of the external tank to the boosters as early as this
weekend.
WORK COMPLETED:
