The next Aqua MODIS Lunar Calibration Roll will be scheduled for 2004/062 (March 2, 2004). Data collect time is 07:24:18 to 07:30:48 GMT. The roll angle will be -14.1956 degrees.

The second Aqua Inclination Adjust Maneuver (IAM#2) will occur on 2004/075 (March 15, 2004), between 15:09:22 and 15:40:48 GMT. The maneuver will consist of a -79.2 degree yaw and a 600-second thruster burn. All of the maneuver will be completed in Spacecraft Night.

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