This Week’s Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Monday, December 16, 2002

2002/350 21:02:00-21:15:11 ATC MOD_OA16_SD_SCREEN_FXD_SUN_A.1 OA-16: SD/SDSM Screened - SDSM Fixed at SUN View - A Side

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.

An additional set of 2 days of six yaw maneuvers each day to facilitate SD/SDSM “Screened” calibrations is being scheduled for January 8-9, 2002.

The Terra Deep Space Calibration Maneuver is still postponed.

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:
