Gravity Probe B

Testing Einstein's Universe

WEEKLY HIGHLIGHTS FOR WEEK ENDING 9 July 1999:

STANFORD HIGHLIGHT

The gyroscope payload test team has successfully completed the room temperature testing of flight gyroscopes 3 and 4. The testing included a trial caging, levitations of the gyroscopes, a 0.3 Hz spin of each gyroscope, and an offset of each spinning gyroscope to its spinup location. After completing the testing of gyroscope 3 and 4, the probe was rotated and reconfigured to allow similar testing on gyroscopes 1 and 2. The team members involved in this work include Rob Brumley, Bruce Clarke, Russ Lesse, Chris Gray, and Dorenne Ross.
