This Week's Scheduled MODIS Activities Not Completed:


This Month's Upcoming MODIS Events:

Calibrations for March will include a Black Body Cycle (DOY 064-066), an SDSM Screened (DOY 073), a Lunar Roll (DOY 074), and an SRCA Radiometric (DOY 087).


There will be an Aqua Inclination Adjustment Maneuver (IAM) #28 on DOY 081 (03/22/2011). The maneuver start time is set for 081/15:44:17 and the maneuver end time is set for 081/16:15:37. The preliminary loss of pointing accuracy times are 081/15:44:17 - 081/16:30:37. MODIS SVD and NAD doors are scheduled closed on 081/16:16:37-16:18:07 in case there is an issue completing the maneuver. This scheduling is only a precaution and we do not expect MODIS doors to close.

MODIS Anomalies:


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.
