Update #3: The root cause for this data outage is a Command Data Processor (CDP) reset on the S-NPP Spacecraft that occurred at 05:28 UTC on July 24, 2024. Engineering has started spacecraft recovery activities. The S-NPP spacecraft is back to nominal mission point as of 18:22 UTC on July 24, 2024. All science data remains unavailable and will not be recoverable until further notice; however, all instruments are in a safe state.
PDA OPS requests for all S-NPP Science products were disabled at 15:10 UTC on July 24, 2024. High Rate Data (HRD) is also disabled.
The NOAA-21 and NOAA-20 satellites will continue to provide JPSS science data needs as the primary and secondary satellites, respectively.
UPDATE: 2) NPP is in SAFE HOLD. No data will be attempted to be recovered. No further updates will be provided until SMD is received from the spacecraft.
UPDATE #1: SMD not received from rev 66016. GSE's are aware of the situation and are investigating.
