Contingency for Terra Inclination Maneuver; the commands in this activity are inhibited
2003/189 16:16:23 - 16:18:04 ATC MOD_CLOSE_NAD_SVD.1 Closes MODIS Nadir and Space View doors

Wednesday, July 9, 2003

2003/190 20:18:31 - 20:27:19 ATC MOD_OA16_SDSM_SCRN_NO_DOOR_A.4 OA16: SD/SDSM screened side A, no door movement

Maneuvers:

The next MODIS lunar calibration will be on July 18, 2003 (203/199). The roll angle will be -10.3692 degrees, and data collection will be from 03:14:57 - 03:21:27 GMT.

Three Terra inclination maneuvers are currently being planned for July 8th, August 5th, and August 7th, 2003. For each inclination maneuver, a contingency activity will be scheduled in the stored command load to close the MODIS Space View and Nadir doors prior to entering daylight following the maneuver, but the commands will be inhibited after the spacecraft successfully returns to a nominal attitude.

MODIS Anomalies:

During the May 6, 2003 (doy 2003/126) Terra Solar Diffuser calibration with the Solar Diffuser Door in the full open position, the telemetry mnemonic, MOD_CR_DR_SDS_OPEN, did not change from NOT_OPEN to OPEN as was expected. A recovery plan was implemented on July 2nd, 2003. The Solar Diffuser Door was opened but the screen was left closed. The Solar Diffuser Door will remain in this screened position for the remainder of the mission. The Solar Diffuser Stability Monitor will be powered and run through a calibration sequence once per week when the solar diffuser is illuminated by the sun.

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 and the Solar Diffuser Door at the Screened position.

MODIS Telemetry Trends:

Nominal telemetry trending is ongoing.
