This Week’s Scheduled MODIS Activities Not Completed:
None.
Upcoming MODIS Events:
A period of day rate data collection over groundtrack night is being planned for the near future, but a specific date/time have not yet been determined.
March calibrations for the PFM MODIS instrument will include an SRCA full radiometric, an SRCA full spatial, and bi-weekly SD calibrations.
Maneuvers:
The next Terra MODIS lunar calibration is being planned for March 22, 2003 with a roll angle of -20.0000 degrees and data collection from 07:09:50 to 07:16:20 GMT. The optimal roll angle is actually -20.6 degrees, but the moon will still be in the space view port field of view using the maximum allowed roll of -20 degrees.
The next Terra Drag Make-up Maneuver is being planned for March 6th, 2003 at approximately 19:17 GMT.
The Terra Deep Space Calibration Maneuvers are now being planned for March 26th, 2003 (without the moon in the instruments fields of view) and April 14th, 2003 (with the moon in the spacecraft orbit plane). The maneuver will start at 2003/085-14:53:40 GMT and will be completed at 15:29:33.
For approximately 36 minutes prior to the maneuver, the MODIS instrument will be configured to collect data at the formatter Night rate. During the maneuver, data collection will be at the formatter Day rate. Following the maneuver, the high-rate instrument data feeds (including MODIS’) to the Terra solid state recorder will be disabled until the maneuver data are successfully captured on the ground through two different downlink opportunities.
MODIS Anomalies:
None.
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody maintained at 290K.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
