This Week’s Scheduled MODIS Activities Not Completed:


Upcoming MODIS Events:

Calibrations for September include biweekly SDSM, monthly SRCA Full Radiometric, and bimonthly SRCA Full Spatial.


There will be no Aqua MODIS Lunar Calibration Roll in September 2004. The necessary roll angle is greater than –25 degrees (exceeding the -20.0 degree limit).

The Aqua satellite will be executing a series of five additional (there have already been 2 for Aqua) Inclination Adjust Maneuvers (IAM) between DOY 2004/258 and 2004/317 (September 14, 2004 and November 12, 2004, respectively). The planned dates for each maneuver (exact time and duration for each to be updated as the events draw near):

2004/258 (September 14, 2004) IAM #3
2004/265 (September 21, 2004) IAM #4
2004/272 (September 28, 2004) IAM #5
2004/279 (October 5, 2004) IAM #6
2004/286 (October 12, 2004) IAM #7

No official date has yet been scheduled for the Aqua Deep Space Calibration pitch maneuver(s).

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.
