This Week’s Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Additional calibrations planned for November:

  • Biweekly SD/SDSM Calibrations
  • Monthly SRCA Full Radiometric
  • Bimonthly SRCA Full Spatial

Maneuvers:

The next MODIS lunar calibration maneuver is planned for November 24, 2002 (2002/328). Data collection will be from 19:52:41 to 19:59:11 GMT and the roll angle will be -10.1320 degrees.
