This Week's Scheduled MODIS Activities Not Completed:
This Month's Upcoming MODIS Events:
December’s routine activities include an SDSM Closed on 2020/343, PV Ecal on 2020/348, SDSM Closed on 2020/364, and Blackbody on 2020/365.
Non-routine activities include a Lunar Roll on 2020/340.
Next Week's MODIS Events:
Saturday, December 5, 2020
Lunar Roll Maneuver (-7.5766 degrees)
2020/340 03:22:54 ATC MOD_OA04_NIGHT_RATE.1 (1:53 early, in addition to 02:58 delta time due to implementation of STS scheduling, total shift of 4:51 early)
2020/340 04:00:01-04:03:47 ATC MOD_OA08_ROLL_MAN_EV.1
2020/340 04:18:54 ATC MOD_OA03_DAY_RATE.2 (1:53 late, in addition to 00:00 delta time due to implementation of STS scheduling, total shift of 1:53 late)
Tuesday, December 8, 2020
2020/343 21:08:54-21:17:42 ATC MOD_OA16_SDSM_SCRN_NO_DOOR_A.4
OA-16: SD/SDSM screened side A, no door movement.
Terra Lunar Roll will take place on 2020/340.
Terra DMU #125 will take place on 2020/351.
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 STS File scheduling was implemented on 2020/313. The STS Files create alternating orbits allowing for coverage of the poles and lengthen Night Rate collection by 00:05:56 each orbit.
MODIS Telemetry Trends:
Nominal telemetry trending is ongoing.
