Lunar Roll Maneuver (-11.6949 degree roll)
2003/043 13:00:08 - 13:46:12 MOD_OA03_FR_DAY_RATE.1
2003/043 13:46:12 - 13:58:34 MOD_OA03_FR_NIGHT_RATE.2
Formatter Night rate transition 03:23 early to compensate for extra day rate during roll maneuver
2003/043 13:58:34 - 14:05:20 MOD_OA08_ROLL_MAN.1
Lunar calibration during spacecraft roll maneuver
2003/043 14:05:20 - 14:42:24 MOD_OA03_FR_NIGHT_RATE.2
2003/043 14:42:24 - 15:28:28 MOD_OA03_FR_DAY_RATE.1
Formatter Day rate transition 03:23 later to compensate for extra day rate during roll maneuver
February calibrations: biweekly SDSM, monthly SRCA Radiometric, and bimonthly PV Ecal.
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.
Maneuvers:
The next Aqua MODIS Lunar Calibration via roll maneuver will be on February 12th, 2003 (2003/043). The roll angle will be -11.6949 degrees and the data collection period will be from 13:58:42 to 14:05:12 GMT.
The Deep Space Calibration pitch maneuver(s) have been indefinitely suspended pending mission review.
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. A slight increase in the radiative cooler intermediate stage temperature has been observed along with a decrease in the focal plane heater power usage. The radiative cooler temperatures has not leveled off as dramatically for the FM1 MODIS as they did for the PFM MODIS, but the intermediate stage temperature has only risen about 1 degree Celsius and the focal plane heater still has approximately 40mW of power margin remaining. These telemetry points will continue to be closely monitored.
