This Week’s Scheduled MODIS Activities Not Completed:

None

Upcoming MODIS Events:

Calibrations for August will include biweekly SDSM and quarterly SRCA Full Spatial.

Maneuvers:

The next Terra MODIS Lunar Calibration Roll will be on DOY 2005/265 (September 22, 2005). The roll angle will be -12.4733 degrees. Data collect will be from 06:28:28 – 06:34:58.

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:

On DOY 2005/238, SSR PWA containing supersets 54 and 55, was lost. These supersets belonged to the MODIS science buffer. Those supersets were moved to the Bad List, and because of this, a data loss between 23:09:46 and 23:23:57 should be expected. Science data that was contained within those supersets was also lost. This PWA loss is similar to the ones that have occurred in the past. The FOT is currently discussing plans to recycle the SSR in the hopes that it will bring back some of the lost PWA’s.
