WEEKLY HIGHLIGHTS FOR WEEK ENDING 17 SEPTEMBER 1999:
All four of the flight gyroscopes were levitated and slowly spun. Each gyroscope levitated cleanly on every levitation attempt. The measured spin down rate for each gyroscope met requirement. These excellent results indicate that the gyroscopes are physically clean and of high quality, and that the gyroscopes are consistent with the flight need. The gyroscope team members involved in this work include Rob Brumely, Paul Bayer, Bill Bencze, Bruce Clarke, Chris Gray, and, David Hipkins.
