March calibrations for the FM1 MODIS instrument include an SRCA full radiometric, an SRCA full spatial, and weekly SD calibrations.
A flight software patch is planned to the Control Processor CP07 mode transition table to not turn off the instrument formatter when MODIS transitions to Safe Mode. However, this patch is still postponed until the Aqua BST patch has been implemented.
Maneuvers:
The next FM1 MODIS lunar calibration via spacecraft roll maneuver is March 14th, 2003 (2003/073) with data collection from 07:37:46 to 07:44:16 GMT and a roll angle of -13.7657 degrees.
The Deep Space Calibration pitch maneuver(s) are still postponed pending the results of the Terra Deep Space Calibration maneuvers currently planned for March 26th and April 14th, 2003.
MODIS Anomalies:
Work is still underway to fix the current BST patch as well as modify the final BST patch that was nearing final review approval. This fix will solve the problem of MODIS Ground Command transactions being disabled by MODIS Stored 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. The radiative cooler temperatures have leveled off with approximately 37mW of margin left with the SMIR focal plane heater These telemetry points will continue to be closely monitored.
