WEEKLY HIGHLIGHTS FOR WEEK ENDING 8 OCTOBER 1999:
The magnetometer team has successfully completed functional test of the 4 payload magnetometers and has held the acceptance review for this flight hardware. Team members involved in this work included Sei Chun, Ernie Iufer, Russ Leese, Jim Lockhart, and Dorrene Ross.
The cryogenics team has completed the first set of thermal measurements on the GP-B payload. The configuration for these measurements was as follows: the main liquid helium tank was at a temperature of 4.2 K, there was liquid helium in the gaurd tank, and the well and probe were evacuated. The purpose of these measurements was to help provide a better understanding of unexpected temperatures found in the neck region of probe C. Team members involved in this work included Jim Maddocks, Dave Murray, Mike Taber, and Tom Welsh.
