January calibrations: biweekly SDSM, monthly SRCA Radiometric, bimonthly SRCA Spatial, quarterly SRCA Spectral, and quarterly Black Body.
February calibrations: biweekly SDSM, monthly SRCA Radiometric, and bimonthly PV Ecal.
Two new SRCA calibrations will be performed on 2003/028 and 2003/029 (see above); 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 February 21, 2003 (2003/052), with data collection from 01:08:08 to 01:14:38 (GMT). The roll angle will be -10.3622 degrees.
The Terra Deep Space Calibration Maneuvers are now being planned for March 25th, 2003 (without the moon in the instruments fields of view) and April 14th, 2003 (with the moon in the spacecraft orbit plane). Details of these maneuvers will be provided closer to the event dates.
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. The intermediate stage radiative cooler temperature that had been increasing has now leveled off. The cooler temperatures and focal plane heater power will continue to be monitored with the expected solar beta angle changes.
