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:

None

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.
