Maneuvers:
A drag makeup maneuver was performed by the FOT at 017/19:38:00 to 017/21:08:00.
The next MODIS Lunar Calibration Roll Maneuver is planned for 2001/043, February 12th
MODIS Anomalies:
No formatter anomalies have been detected since switching to B-side science operations. The MODIS IOT is continuing to monitor changes with the radiative cooler temperatures and focal plane power.
General Instrument Comments:
MODIS is in Science Mode on the B-side with the SVD and NAD open, operating with the Formatter Resolution Flight Software Patches (FRFSP). No new events have been witnessed by the FRFSP since the B-Side Transition on DOY 2000/304.
MODIS Telemetry Trends:
The Radiative Cooler intermediate stage temperature has slowly been increasing since approximately day 2000/240. During this time the LWIR focal plane heater margin has been decreasing. The IOT is continuing to trend these telemetry mnemonics.
Temperature trends are correlating with the solar beta angle. This includes a steadying of the intermediate stage outgas temperature. This temperature is expected to increase again when the beta angle gets smaller.
Non-MODIS Significant Events:
None.
