Maneuvers:
None
MODIS Anomalies:
None
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody maintained at 290K and the Solar Diffuser Door at the Screened position.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
Non-MODIS Significant Events:

Following the Inclination Maneuver on DOY 286 (10/13/09), Terra experienced a Hex Bay Battery (BBAT) cell #50 failure and simultaneously (or close to same time) experienced a Battery Heater Control Electronic anomaly which prevents controlling the temperature for 5 of the 9 heater groups within BBAT. Cell #50 has failed and is non-recoverable. Battery temperatures have stabilized and battery cell temperatures are within an acceptable range. Terra has a robust power system with two 54 cell batteries that feed a power control system that maintains a stable 120V spacecraft power bus even if multiple cells fail. Terra is capable of continuing nominal operations with multiple cell failures. Science data acquisition has remained nominal throughout the anomaly and troubleshooting timeframe. Information will be updated periodically.
