Maneuvers:

The next Drag Make-Up (DMU) maneuver is planned for DOY 2003/253 (September 10, 2003). The time of the maneuver is 17:55:00 GMT. The burn duration is scheduled for 30 seconds.

The next Lunar Roll Calibration is planned for DOY 2003/258 (September 15, 2003). Data collect between 13:13:22-13:19:52 GMT. The requested roll angle is -8.9233 degrees.

The next Terra inclination maneuvers are expected in October of 2004.

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.
