This Week's Scheduled MODIS Activities Not Completed:
---
Lunar Roll Maneuver (-18.9184 degrees)
This month's Terra lunar roll did not occur as planned. Due to an error with Terra's ATC command scheduling, the S/C did not perform the requested roll maneuver. The MODIS commands still took place as scheduled, however the moon was not visible through the Space View Port.
This Month's Upcoming MODIS Events:
---
April's routine activities include a SDSM_Closed on 2018/107 and a Lunar Roll on 2018/095.
Non-routine activities include a Lunar Roll on 2018/095.
Maneuvers:
---
Terra Lunar Roll will take place on 2018/124.
Terra DMU #105 took place on 2018/026.
Terra IAM #51 took place on 2018/053.
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.
