WEEKLY HIGHLIGHTS FOR WEEK ENDING 12 JANUARY 2001:
PAYLOAD IN FINAL PREPARATION FOR SHIPMENT TO ACOUSTIC TEST
The payload test team has continued in the past week to prepare the payload for shipment to Lockheed Martin for acoustic test. At the conclusion of gyro testing CM-14, 100 % of the payload's science functions had been successfully demonstrated. Two caging anomalies however, had prevented caging 3 of the 4 flight gyroscopes. As a result of these anomalies and our prior promising uncaged gyro test results we are planning within the next one to two months (tests are already underway) to conclusively demonstrate that we do not need the caging function. With this in mind, the fourth gyroscope was intentionally uncaged during the past week. GSE external to the probe and dewar has been reconfigured for shipment.

SPACE VEHICLE HIGHLIGHT
ACOUSTIC TEST HANDLING DRY RUNS COMPLETE
The Space Vehicle Tilt Dolly, and its associated hardware arrived from Vandenberg Air Force Base. The tilt dolly stand was then fit checked in the LM B/159 Acoustic Cell. The dolly was first placed in the position to be used for dewar servicing. The dolly was then lifted and placed onto the acoustic test stand pedestals that will support the dolly and Science Payload during the up coming Payload acoustic test. The dolly was then removed from the pedestals and set on the ground. This activity successfully completes dry run activities in the acoustic cell.
ECU PASSES CONDUCTED EMISSIONS TEST
The ECU has passed conducted emission, now testing for radiated emissions. EMI testing is projected to end by 2 January.
FORWARD SRE TRR SCHEDULED FOR 18 JANUARY
The Fwd SRE TRR will be held in 18 January to allow start of pyroshock and random vib testing of the two forward units. Failure analysis of the failed 12V-power supply in the SRE aft A unit is scheduled to be concluded by 21 Jan.
