WEEKLY HIGHLIGHTS FOR WEEK ENDING 1 JUNE 2001:
ARTIFICAL STAR PAYLOAD TEST NEARING COMPLETION
The Artificial Star III team has successfully performed a battery of Payload Verification II tests during the past week. Most test procedures have been
performed and nearly all the data have been reduced. A few unresolved issues remain on the focus of AS3 that effect the results from the tests. These
items are being investigated to confirm the scale factor and Strehl ratio of the telescope. The plan is for the team to complete the Payload Verification
Test II operations this weekend and to remove the Artificial Star this coming Monday.

SRE DELIVERED FOR PAYLOAD TEST
One forward and one aft SRE have been delivered to Stanford to support the upcoming flight electronics checkout on the payload. The second
forward unit is planned to be delivered to Stanford next week.
SUCCESSFULLY COMPLETED SPACECRAFT INTERPOINT REWORK
The GP-B team successfully completed post-Interpoint power supply rework testing of the Attitude Control Electronics (A and B side), including
interfaces to the coarse sun sensor, magnetometer, mass trim mechanisms, thruster isolation valves (TIV), remotely actuated valves (RAV), thrusters,
magnetic torque rods, sunshade shutter, CCCA (A) and 1553 cross-strapping. These activities also sucessfully completed the post acoustic testing of the
sunshade shutter including open, close and launch mode cycles.
