MODIS IOT Aqua Weekly Report
Mission Operations Days: 2002/201 to 2002/207
July 21, 2002 00:00:00 GMT to July 27, 2002 00:00:00 GMT
Note: Although this report only officially covers up through 00:00 GMT on July 27th. On Monday July 29th at 20:23 GMT, the Aqua spacecraft entered Safe Mode. This also put MODIS into Safe Mode and closed the Space View and Nadir doors.

None
This Week's Scheduled MODIS Activities Not Completed:
None
Upcoming MODIS Events:
After recovery from Safe mode (see note at top of report), weekly SDSM calibrations, a Blackbody calibration, and an SRCA Full Radiometric calibration will be performed.
Maneuvers:
There will not be a lunar calibration roll maneuver on Aqua in August. The required roll angle would have exceeded the limit of -20 degrees.
The Deep Space Calibration pitch maneuver(s) have been indefinitely suspended pending mission review.
MODIS Anomalies:
None.
General Instrument Comments:
FM1 MODIS is in Science Mode. The SVD and NAD are Open. The Black Body is powered and set at 285K. The Cold Focal Planes are controlling to 83K.
MODIS Telemetry Trends:
MODIS FM1 temperatures have returned to their nominal Science Mode profile trends after the return to Science Mode on DOY 2002/183.
Non-MODIS Significant Events:
None.
