WEEKLY HIGHLIGHTS FOR WEEK ENDING 28 JANUARY 2000:
The gyroscope test team has successfully completed room temperature test of the
4 gyroscopes installed in Probe C. The gyroscopes performed flawlessly in all tests as listed below:
- Gyro levitation
- Rotor spin down rate with the rotor in the center location
- Rotor spin down rate with the rotor in the spin up location
- Rotor cavity exploration
- Caging touch test
- UV system checkout
This excellent room temperature result shows that the integration and test of the payload has left the gyroscopes clean. This result also shows that
the anomalous spin down rates seen in Payload Test I were due to cryo-contamination. This gyroscope contamination source will be eliminated
prior to Payload Test II. The team members involved in this work include R. Brumley, B. Clarke, C. Gray, D. Hipkins, and R. Leese.
