This Month's MODIS Events:
June’s routine activities include an SRCA radiometric on 2022/157, an SDSM Closed on 2022/158, an SRCA spectral on 2022/166, a Lunar Roll on 2022/169, an SRCA spatial on 2022/174, and an SDSM Closed on 2022/179.
Non-routine activities include a Lunar Roll 2022/169.
Terra DMU #137 took place on 2022/153.
Terra Lunar Roll took place on 2022/169.
General Instrument Comments:
MODIS is in Science Mode, using all A-side components, but cross-strapped to Formatter B, with the blackbody nominally maintained at 290K and the Solar Diffuser Door at the Screened position.
Note that the BlackBody will be maintained at 285K.
With the recent Terra SSR reset, MODIS was allocated a full complement of PWAs and no longer needs to reduce its data rate. Starting with September 26, 2021 (2021/269) at 0000z, the MODIS formatter commanding (day rate/night rate) will be synchronized with terminator crossing, which is its nominal timing.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
