This Week's Scheduled MODIS Activities Not Completed:
This Month's Upcoming MODIS Events:
June’s routine activities include an SDSM Closed on 2021/161, a BlackBody WUCD on 2021/167-170, an SDSM Closed on 2021/173, an SRCA Spatial on 2021/175, and a Lunar Roll on 2021/179.
Non-routine activities include a Lunar Roll on 2021/179.
Next Week's MODIS Events:
Tuesday July 06, 2021
2021/187 20:40:40-20:49:28 ATC MOD_OA16_SDSM_SCRN_NO_DOOR_A.4
OA-16: SD/SDSM screened side A, no door movement.
Terra DMU #128 took place on 2021/154.
Terra Lunar Roll took place on 2021/179.
Terra MODIS experienced a PWA failure on 2021/180 starting at 13:17 GMT.
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.
Note that a new STS File scheduling procedure will be implemented on 2021/122. The STS Files create alternating orbits allowing for coverage of the poles and lengthen Night Rate collection by varying amounts each orbit.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
