Submitted by dolink on Wed, 03/23/2022 - 20:00

On February 22, 2022 (2022/053), Aqua FOT reported data losses occuring at regular intervals from MODIS and AIRS science data. The data errors were determined to be due to the solid-state recorder (SSR) where a particular area of memory had failed. The recovery of operations involved marking the area in memory as unusable and resetting the SSR and Formatter/Multiplexer Unit (FMU). The reset was performed on March 23, 2022 and MODIS returned to nominal operation later that day (2022/082 19:47:31).
