Update #1: As of 22:00 UTC (Aug 3, 2021), efforts are underway to return the S-NPP spacecraft back to the nominal mission pointing status. All instruments are in a safe state and science data is not available to users since 12:46 UTC. Tentatively, the instrument recovery back to nominal operations is expected to occur no earlier than 12:00 UTC on Aug 4, 2021 - specifics will follow in another notice update after the 12:00 UTC time frame. All science data during this event will be unrecoverable while the instrument payload is in safe mode and will remain unavailable until the full recovery effort is complete.
