This Week’s Scheduled MODIS Activities Not Completed:
None
Upcoming MODIS Events:
SRCA activities are being developed to measure detector cross talk and will be performed in the near future.
Maneuvers:
The next Aqua MODIS Lunar Calibration via roll maneuver will be on January 13th, 2002 (2003/013). The roll
angle will be -5.3215 degrees and the data collection period will be from 18:45:25 to 18:51:55 GMT.
The Deep Space Calibration pitch maneuver(s) have been indefinitely suspended pending mission review.
MODIS Anomalies:
On November 7, 2002 (DOY 2002/311), a final patch to the BST was outlined. The two MODIS command slots
in the BST that are currently switched will be returned to their original locations. At the same time, the
command slots will be given a one sub-minor cycle delay. This will result in the command slots having the
desired delay period between themselves, and the bus signals that are believed to have caused the occasional
problems with MODIS receiving commands.
General Instrument Comments:
FM1 MODIS is in Science Mode. The SVD and NAD are Open, the survival heaters are enabled, and the Black Body is heated to 285 K.
MODIS Telemetry Trends:
The FM1 MODIS instrument telemetry is trending nominally. 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.
