Upcoming MODIS Events:
Monday, November 4, 2002
2002/308 13:14:17-13:28:15 MCL OA16: SD/SDSM Screened - B Side (MOD_OA16_SDSM_SCREEN.2)
2002/308 14:53:09-15:07:07 MCL OA15: SD/SDSM Open - B Side (MOD_OA15_SDSM_OPEN.1)
Additional calibrations planned for November:
- Weekly SD/SDSM Calibrations
- Monthly SRCA Full Radiometric
- Bimonthly SRCA Full Spatial
A PV ECAL has been requested for around DOY 2002/325. It was not originally planned as part of the Bimonthly schedule, but will be performed.
Maneuvers:
The next Aqua MODIS lunar calibration is planned for November 15, 2002, with data collection from 04:38:56 to 04:45:26 GMT and a roll angle of -9.8076 degrees.
The Deep Space Calibration pitch maneuver(s) have been indefinitely suspended pending mission review.
MODIS Anomalies:
The MODIS commanding anomaly is still being investigated. A patch was loaded to the Aqua spacecraft on Tuesday, October 11, 2002 (DOY 2002/284). This patch switched the MODIS ground-command timing slots with the MODIS stored-command timing slots. This transfers the risk associated with dropping commands from stored commands to real-time ground commands.
No problems have been reported since the patch was loaded and the last command drop occurred on September 2, 2002 (DOY 2002/245). The results of the patch will be evaluated for some time before the next configuration change is made. A final patch to the Aqua Bus Scheduler Task (BST) is being considered which would eliminate the timing issues to MODIS for both ground commands and 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 most recent radiative cooler telemetry analysis indicates significant temperature margin for the cold focal planes.
