MODIS Anomalies:
None.
General Instrument Comments:
MODIS is in Science Mode on the A-side with the SVD and NAD open.
MODIS Telemetry Trends:
Telemetry is nominal.
Non-MODIS Significant Events:
NASA conducted a “Security Scan” on the ops center on Thursday, Day 097. This brought everything except commanding capabilities to its knees. The planning and scheduling system is having a hard time recovering. Everyone associated with Terra Ops was affected. This caused many workarounds to be implemented for Thursday and Friday operations. The MODIS instrument was not in any danger during this event, although it has certainly kept us on our toes!
