This Week’s Scheduled MODIS Activities Not Completed:
None
Upcoming MODIS Events:
Calibrations for June will include biweekly SDSM, monthly SRCA Full and 10W Radiometric, and bimonthly PV Ecal.
Maneuvers:
The next Terra MODIS Lunar Calibration Roll will be on DOY 2005/177 (June 26, 2005). The roll angle will be –15.6638 degrees. Data collect will be from 01:51:21-01:57:51.
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.
