This Week's Scheduled MODIS Activities Not Completed:
Tuesday, October 16, 2007
2007/289 16:19:31-16:21:12 ATC MOD_CLOSE_NAD_SVD.1
IAM Contingency was inhibited because of successful Inclination Adjustment Maneuver
Upcoming MODIS Events:
Calibrations for October will include three biweekly SDSM, one monthly SRCA Full Radiometric, and one monthly Lunar Calibration Roll.
Maneuvers:
Terra successfully performed Inclination Adjustment Maneuver #19 on October 16th (DOY 2007/289). Loss of pointing accuracy for DOY 2007/289 was from 14:37:00-17:49:55.
MODIS Anomalies:
None
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody maintained at 290K and the Solar Diffuser Door at the Screened position.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
