Maneuvers:
There will be a Terra MODIS Lunar Calibration Roll maneuver on DOY 2007/156 with a -19.30° roll slew at 20:07:33 - 20:30:15. Data collection will occur from 20:15:43-20:22:29.
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 SSR-DMU Swap activity (fix for PWA failure on DOY 2007/109) has been scheduled for June 7, 2007 (DOY 158). For the activity science recording will be disabled from approx. 158/10:30:00 until 158/16:30:00 GMT. MODIS Direct Broadcast will not be affected during this time frame. After the swap has been completed the Terra FOT will perform HK playbacks to recover all S/C Engineering and Attitude data via the HK recorder.
