Gravity Probe B

Testing Einstein's Universe

WEEKLY HIGHLIGHTS FOR WEEK ENDING 29 OCTOBER 1999:

STANFORD HIGHLIGHT
The first Mission Operations Center Simulation was successfully completed using ITF engineering units commanded from and sending data to the MOC. The simulation included power on, loading and running the MSS, loading formats and SPCs, formatting switches, fairing separation, and memory dumps. The team members involved in this work include Karl Allmendinger, Mark Anderson, Emily Biss, Jim Burns, Ric Campo, Marvin Candee, Alan Duval, Bill Given, Flora Helin, Sheila Johnson, Tom Langenstein, Frank Mendoza, Dave Meriwether, Phill Ritmuller, Dorrene Ross, Marcie Smith, Kate Trevisan, and Jeff Wade.
The Phase A testing of the payload this past week focused on a set of thermal measurements in which gas was inserted into the probe. Measurements of the resulting temperatures are helping to locate the source of the observed thermal anomalies. Phase A testing is now complete and Phase B work is underway to tilt the dewar and probe. The team members involved in this work include Jim Maddocks, Dave Murray, Mike Taber, and Tom Welsh.
