Based on the current operations plan, calibration activities for June will include an SRCA Full Radiometric, PV Ecal, PC Ecal, and weekly SD/SDSM calibrations.
Maneuvers:
The next MODIS Lunar Roll Maneuver is scheduled for June 10, 2001. The roll angle is - 20.0293 degrees with a data collection from 2001/161-23:07:25 to 2001/161-23:13:55.
MODIS Anomalies:
None
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).
MODIS Telemetry Trends:
Telemetry is trending nominally. The amount of power required by the focal plane heater to maintain 83.0K is still slowly decreasing, although the spacecraft is currently near the minimum absolute solar beta angle for the year.
Non-MODIS Significant Events:
MOPITT Anomaly:
The MOPITT team is still working to recover their instrument to science operations.
