WEEKLY HIGHLIGHTS FOR WEEK ENDING 12 June 1998:
STANFORD HIGHLIGHT
Dr. Doron Bardas has completed the fabrication and testing of
the main
vacuum valves for the GP-B Science Mission. Three probe
valves (2 flight
and one spare) and 4 exhaust valves (spare to
be delivered in 3 weeks) have
been delivered to Stanford. This
represents a complete flight set of valves.
SPACE VEHICLE HIGHLIGHT
Relativity Mission Electrical Product Development Team members
attended the
successful Final Data Review for the spacecraft
magnetic torquer bars at
Ithaco Space, Inc., Ithaca, New York
on Tuesday, June 2. Magnetic moment
scale factor, residual
moment, impedance, inductance and mechanical
measurements
data was reviewed and trended to ensure consistent performance
between baseline function, post vibration functional, and post
thermal
functional testing. All three torquer bars
successfully performed within
their specification requirements.
The torquer bars are being packaged and
shipped to LMMS for
installation onto the space vehicle.
