Tuesday, April 15, 2003
The Aqua patch to the Bus Scheduler Task will be loaded to the spacecraft. This will correct the MODIS dropped / delayed command anomaly. If this patch is successful, the Aqua MODIS SRCA crosstalk calibration will be rescheduled and a patch to the MODIS control processor mode transition table will be performed in the near future.
April calibrations for the FM1 MODIS instrument include an SRCA full radiometric, an SRCA spectral, a PV Ecal, a Lunar Calibration Roll, and weekly SD calibrations.
Maneuvers:
The next FM1 MODIS Lunar Calibration via Spacecraft Roll Maneuver is April 12, 2003 (DOY 2003/102) with data collection from 20:23:18 to 20:29:58 GMT and a roll angle of -10.4528 degrees.
The next Aqua Drag Make-up maneuver is scheduled for April 24th, 2003 at approximately 16:49 GMT.
The Deep Space Calibration pitch maneuver(s) are still postponed pending the results of the Terra Deep Space Calibration maneuvers currently planned for 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. After the data are analyzed, a decision will be made regarding which 10W lamps to use for the nominal schedule of SRCA calibrations.
The test review for the second Aqua Bus Scheduler Task (BST) patch was conducted on Wednesday, April 9th, 2003. The Command Authorization Meeting (CAM) for this patch is planned for Monday, April 14th and if approved, the patch will be loaded on Tuesday, April 15th.
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.
