Thursday, November 9, 2006
Lunar Roll Maneuver (-13.28 deg roll)
2006/313 16:58:14 ATC MOD_OA03_FR_NIGHT_RATE (03:23 early)
2006/313 17:35:31-17:42:17 ATC MOD_OA08_ROLL_MAN
2006/313 17:54:16 ATC MOD_OA03_FR_DAY_RATE (03:23 late)

Maneuvers:

The next Terra MODIS Lunar Calibration Roll will be on DOY 2006/313 (November 9, 2006). [Previous reports stated 2006/315, which was incorrect.] The roll angle will be -13.2814 degrees. Data collect will be from 17:35:39-17:42:09.

The next two Terra Inclination Adjustment Maneuvers (IAMs) will occur on November 14 and 21 - DOY 2006/318 and 2006/325, respectively. [NOTE: the date of the second maneuver changed since the last weekly report.] If needed, a back-up IAM would be performed on 2006/334. The times of the maneuvers and the MODIS contingency activities are tentatively scheduled as follows:

Tuesday, November 14, 2006
2006/318 15:46-16:21 Terra Inclination Adjustment Maneuver #16
(planned - not yet scheduled) 2006/318 16:21:38-16:23:19 ATC MOD_CLOSE_NAD_SVD.1
IAM Contingency: Closes the NAD and SVD 100 seconds prior to S/C Day
Note: This activity will not execute if the IAM is successful.

Tuesday, November 21, 2006
2006/325 15:52-16:28 Terra Inclination Adjustment Maneuver #17
(planned - not yet scheduled) 2006/325 16:28:19-16:30:00 ATC MOD_CLOSE_NAD_SVD.1
IAM Contingency: Closes the NAD and SVD 100 seconds prior to S/C Day
Note: This activity will not execute if the IAM is successful.

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.
