On August 28, 2018, S-NPP CERES FM5 will be commanded into Diagnostic and Standby Mode to permit the upload of new FSW PROM Dump2 that Langley Research Center (LaRC) requested. This FSW patch that contains a modified instrument sequence for slot thirteen which was previously unused.
This new FSW will help LaRC verify the health of the onboard instrument PROM chips to ensure they haven't been damaged by space weather.
