Gravity Probe B

Testing Einstein's Universe

WEEKLY HIGHLIGHTS FOR WEEK ENDING 04 SEPTEMBER 1998:

STANFORD HIGHLIGHT
Ms. Ming Luo has successfully completed testing the sixth science mission SQUID package. This achievement allows for "cherry picking" the best four SQUIDs as the primary flight SQUIDs while maintaining the remaining two SQUIDs as flight backups. Photo 1: Ming Luo Photo 2: SQUID

SPACE VEHICLE HIGHLIGHT
Relativity Mission spacecraft electrical power distribution has been successfully validated during the recently completed power-on phase of spacecraft testing. These tests verified that all switched and unswitched power leads (including pyro functions) functioned properly and are of the correct polarity. Power distribution testing also validated the correctness of the Power Distribution Unit command harness.
