Wednesday, December 7, 2005Terra inclination adjust contingency activity
2005/341 15:20:41-15:22:22 ATC MOD_CLOSE_NAD_SVD.1
(100 seconds prior to S/C day, orbit 31765)
Maneuvers:
The next Terra MODIS Lunar Calibration Roll will be on DOY 2005/354 (December 20, 2005). The roll angle will be –3.4356 degrees. Data collect will be from 12:58:44-13:05:14.
The Terra spacecraft will be performing an inclination adjust maneuver on December 7, 2005 (doy 341). Expect abnormal science data. Details below:
-90.7 deg. Yaw start: 341 / 14:45:42
Maneuver (burn) start: 341 / 14:58:13
+90.7 deg. Yaw start: 341 / 15:09:53
+90.7 deg. Yaw complete: 341/ 15:20:24
Loss of Pointing Accuracy 12:45:42z
Regain of Pointing Accuracy 17:50:24z
There will also be inclination adjust maneuvers on days 347 and 349.
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 and the Solar Diffuser Door at the Screened position.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
