Maneuvers:

The January Lunar Calibration Roll will be on day 2005/030 (January 30, 2005). Data collect will be from 09:43:03-09:49:33 GMT with a roll angle of –4.6573 degrees.

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:

Terra Solid State Recorder Anomaly

Overview:

The SSR Anomaly is still under investigation. MODIS currently is operating with 34 Supersets allotted for its buffer. The FOT is currently planning on power cycling the SSR in an attempt to regain functionality of the “bad” PWA’s. This activity was being planned for the final week of January 2005, but has been put on hold until further notice.
