Maneuvers:
There was a Terra Inclination Manuever #24 on DOY 286 (10/13/09). The slew out start time was 286/14:57:41 and the slew back end time was 286/15:29:21. The maximum commanded yaw angle was -89.9082 degrees.
Loss of pointing accuracy times were 286/13:55:00 . 286/17:18:00.
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.
Non-MODIS Significant Events:
The EMOS mission status webpage (which includes instrument data loss records) can be found at the following URL. Note that a password is now required to access the EOS mission links web pages. There are directions at the URL below for how to obtain a username/password.
Following the Inclination Maneuver on DOY 286 (10/13/09), Terra experienced a Hex Bay Battery (BBAT) cell #50 failure and simultaneously (or close to same time) experienced a Battery Heater Control Electronic anomaly which prevents controlling the temperature for 5 of the 9 heater groups within BBAT. Investigation into the issue is on-going. Information will be updated as it is known.
