This Week's Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

September calibrations will include weekly SDSM, monthly SRCA Full Radiometric, monthly SRCA 10-Watt Radiometric, bimonthly SRCA Full Spatial, and a Lunar Roll Calibration.

Tuesday, September 2, 2003

2003/245 20:28:34-20:37:22 ATC MOD_OA16_SDSM_SCRN_NO_DOOR_A.4 OA16: SD/SDSM screened side A, no door movement.

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.
