Terra Solid State Recorder Reset - Update

Sep 21, 2021

A reset of the Terra Solid State Recorder (SSR) to recover the on-board memory lost from Printed Wire Assembly (PWA) anomalies during the mission period is scheduled to start DOY 265 (9/22/21) at 11:00z and is expected to go into early DOY 266 (9/23/21). During the activity the SSR Science Data Record will be disabled and instrument science data will not be captured. The Science Data Record will be will re-enabled once all requisite activities are completed. Direct broadcast transmissions are not impacted by this event.

Update - The MODIS instrument continued to be in science mode and nominal operations through and after this reset activity. Initial assessment suggests that all the PWAs are now operational, but will await further confirmation before adjusting the data collection schedule.
