SMOV Status & Planning Meeting Notes
6/24/09
Notes provided by Burley (richard.j.burley@nasa.gov), Biagetti (biagetti@stsci.edu, and others as
indicated.
- Summary:
The meeting included an ops briefing for the upcoming Vehicle Disturbance
Test and associated gyro reconfigurations. The SI C&DH anomaly investigation continues;
the ARB reports out tomorrow, possibly with recommendations for upcoming SMOV
operations. Pending these recommendations, COS NUV and STIS MAMA operations remain
temporarily halted. The ACS suspended mid-day, yesterday, apparently due to a loss of
communication between the CS and the ASIC. A tiger-team investigation is underway.
WFC3 has been returned to normal Operate mode and is performing internals. Its first
external observation is scheduled for late today. The COS recovery from yesterday’s
Suspend was successfully completed in time for the scheduled resumption of the FUV highvoltage ramp-up. STIS CCD internals are continuing.
