This Week's Scheduled MODIS Activities Not Completed:

At successful completion of the Aqua IAM, the following activity was inhibited and did not execute (this was the planned result).

Wednesday, March 31, 2004

In support of Aqua Inclination Adjust
2003/091 15:43:16-15:44:16 MCL MOD_NAD_AND_SVD_TO_CLOSED.1 Scheduled 90 seconds prior to S/C Day (15:44:46)

Upcoming MODIS Events:

Calibrations for April will include biweekly SDSM, monthly SRCA Full Radiometric, bimonthly PV Ecal, and quarterly SRCA Full Spectral and Black Body calibrations.


The next Aqua MODIS Lunar Calibration Roll will be scheduled for 2004/121 (April 30, 2004). Data collect time is 17:12:38 to 17:19:08 GMT. The roll angle will be -6.9795 degrees.

The second Aqua Inclination Adjust Maneuver (IAM#2) was successfully completed on DOY 2004/091 (March 31, 2004), between 15:10:59 and 15:42:20 GMT. The maneuver consisted of a -79.2 degree yaw and a 600- second thruster burn. The entire maneuver was completed in Spacecraft Night. Initial results reported less than a 2% deviation from the planned event (well within expected margins).

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.
