WEEKLY HIGHLIGHTS FOR WEEK ENDING 15 JUNE 2001:
FLIGHT ELECTRONICS IN-TEST ON THE PAYLOAD
The forward and aft ECU and the forward SREs (A and B) and aft SRE have been installed on the GP-B payload. Both systems have been powered up. The ECU has successfully measured payload temperatures. The SRE has successfully flux locked each of the four flight SQUIDs. The tests on the two systems will continue concurrently. Some external cable issues have been uncovered. These issues are currently in-work and should be straightforward to resolve.

MISSION OPERATIONS CENTER PHASE 1 VERIFICATION COMPLETE
The MOC team successfully completed phase 1 of their verification program for the MOC ground system. 17 requirements were tested, verifying the basic real-time and data processing functions of the MOC. The team was led by Bill Given, with lots of support from Ric Campo, Jennifer Mullins, Mark Castanon and many others. The real-time run was made on May 25, when a mini-launch day sequence was commanded from the MOC using the ITF electrical mock-up. Pre-launch loads were loaded into EEPROM; the launch sequence was initiated; Ground Network and Space Network tracks confirmed operations at all command and telemetry rates; data from the SSR was returned and verified operations in all flight formats. Post-processing was performed by both LM's Engr Data Reduction tool and the Stanford TCAD system.
PAYLOAD ELECTRONICS DELIVERY
The GP-B team successfully delivered the flight Forward SRE B box to Stanford University. The box has been integrated with the GP-B Payload and initially powered up prior to supporting Payload Phase B testing at Stanford.
