May calibrations for the FM1 MODIS instrument include bimonthly SRCA Spatial, monthly SRCA Radiometric, a Lunar Calibration Roll, and weekly SD/SDSM calibrations.
Maneuvers:
The next FM1 MODIS Lunar Calibration via Spacecraft Roll Maneuver is May 12, 2003 (DOY 2003/132) with data collection from 05:55:36 to 06:02:06 GMT and a roll angle of -6.7176 degrees.
The Deep Space Calibration pitch maneuver(s) are still postponed pending the results of the Terra Deep Space Calibration maneuvers which took place on March 26 and April 14, 2003.
MODIS Anomalies:
Recent SRCA calibrations have shown that SRCA lamp #2 is not producing the same output characteristics as the other SRCA 10 Watt lamps. Upcoming SRCA Full Radiometric and Full Spatial calibrations will use the backup lamp (#4) in lieu of lamp #2. The SRCA Cross Talk Calibration has also made use of this backup lamp configuration. After the data are analyzed, a decision will be made regarding which 10W lamps to use for the nominal schedule of SRCA calibrations.
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 and the radiative cooler temperatures have stabilized.
