This Week’s Scheduled MODIS Activities Not Completed:
None
Upcoming MODIS Events:
The next MODIS Lunar calibration will be scheduled for January 22, 2003 (doy 022).
Quarterly SRCA spectral and black body, bi-monthly SRCA spatial, monthly SRCA radiometric, and bi-weekly SDSM calibrations.
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 MODIS Lunar calibration will be scheduled for January 22, 2003 (doy 022), from 15:56:36 to
16:03:06. Roll angle will be –1.0332 degrees.
An additional set of 2 days of six yaw maneuvers each day to facilitate SD/SDSM “Screened” calibrations is
being scheduled for January 15-16, 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:
