2004/271 21:52:04-22:06:02 MCL MOD_OA15_SDSM_OPEN.1 OA-15: SD/SDSM Open - B-Side

For Aqua Inclination Adjust Maneuver (#5)
2004/272 16:00:40-16:01:40 MCL MOD_NAD_AND_SVD_TO_CLOSED.1
Scheduled 90 seconds prior to S/C Day (16:02:10)

Maneuvers:

The next Aqua MODIS Lunar Calibration Roll will be on DOY 2004/297 (October 23, 2004). The roll angle will be -16.6865 degrees for a nominal 6:30 (390 second) collection.

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 Executed: 15:23:36-15:54:56 slewed off nominal pointing 550 second thruster burn
2004/272 (September 28, 2004) IAM #5 Planned: 15:28:59-16:00:19 slewed off nominal pointing 550 second thruster burn
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:
