2002/269 15:29:34 ATC FR to DAY Rate 3 minutes, 23 seconds LATE. Done in to compensate for extra day rate at night in roll activity.

Maneuvers:

The next MODIS lunar calibration maneuver is planned for October 26th, 2002 (2002/299). Data collection will be from 07:11:11 to 07:17:41 GMT and the roll angle will be -12.4510 degrees.

The sixth Terra inclination adjust maneuver has been postponed. No date has been announced for the expected execution time.

The Terra Deep Space Calibration Maneuver is still postponed. The next possible maneuver date is currently being planned for December of 2002.

MODIS Anomalies:

Formatter Error Events:

With this week's successful transition to the B-Side Formatter, there are no more Formatter Errors occurring. Formatter B has been loaded with the Error Statistics Tracking patches that were used in the initial investigation of the A-Side Formatter Error Event Anomaly. Should the same errors ever begin appearing on Formatter B that were occurring on Formatter A, telemetry limits would immediately indicate their occurrences. The currently loaded Error Statistics Tracking patches and the upcoming EEPROM load protect the Formatter B from entering the continuously resetting state that was first detected on Formatter A in August, 2000.

General Instrument Comments:

MODIS is in Science Mode, using all A-side components except Formatter B, with the blackbody maintained at 290K.

MODIS Telemetry Trends:

Nominal telemetry tracking is taking place.
