This Week’s Scheduled MODIS Activities Not Completed:

The second day of yaw maneuver SD calibrations was cancelled, however, the formatter day/night transitions were still scheduled taking into account these calibrations.

Upcoming MODIS Events:

December calibrations will include bi-weekly SD/SDSM events, an SRCA Full Radiometric, and a PV Electronics Calibration.

Two new SRCA calibrations will be performed in the near future; one of these new activities will use the “backup” lamps in the SRCA Spherical Integrating Source (SIS) for the first time on orbit.

Maneuvers:

The next Terra MODIS Lunar Calibration via roll maneuver will be on December 24th, 2002 (2002/358). The roll angle will be -3.3484 degrees and the data collection period will be from 06:50:16 to 06:56:46 GMT.

The next Terra drag make-up maneuver is being planned for December 18th, 2002.

The Terra Deep Space Calibration Maneuver is still postponed.

Twenty-four small-angle yaw maneuvers are in the process of being worked to characterize the MODIS Solar Diffuser. See activity notes above.

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.

MODIS Telemetry Trends:

Nominal telemetry tracking is taking place. A slight increase in the radiative cooler intermediate stage temperature has been observed along with a decrease in the focal plane heater power usage. These telemetry points will be closely monitored for additional changes over the next several weeks.

Non-MODIS Significant Events:

Limited Life Item Status:

Note: The lamp hours and door uses have been recomputed based on a detailed review of early on-orbit activities. Some values have changed slightly.
