This Week's Scheduled MODIS Activities Not Completed:

For Aqua Inclination Adjust Maneuver (#3)
2004/258 15:50:08-15:50:11 MCL MOD_NAD_AND_SVD_TO_CLOSED.1
Scheduled 90 seconds prior to S/C Day (15:51:38)

Upcoming MODIS Events:

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

For Aqua Inclination Adjust Maneuver (#4)
2004/265 15:55:25-15:56:25 MCL MOD_NAD_AND_SVD_TO_CLOSED.1
Scheduled 90 seconds prior to S/C Day (15:56:55)

Maneuvers:

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 Executed: 15:18:11-15:49:31 slewed off nominal pointing 550 second thruster burn
2004/265 (September 21, 2004) IAM #4 Planned: 15:23:36-15:54:56 slewed off nominal pointing 550 second thruster burn
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:

None

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.
