Update #6:  Engineering completed S-NPP spacecraft recovery efforts on Friday, July 17, 2026. The S-NPP spacecraft was returned to nominal mission point as of 19:59:31 UTC on July 15, 2026. ATMS was placed in operational mode on July 16, 2026 at 16:15:43 UTC. VIIRS was placed in operational mode on July 16, 2026 at 19:39:45 UTC.  CERES was placed in operational mode on July 17, 2026 at 14:22:00 UTC. OMPS was placed in operational mode on July 17, 2026 at 15:59:32 UTC. 


As of Monday July 20, 2026, all S-NPP ATMS and VIIRS science products are approved for operational use and PDA OPS subscriptions for these products will be enabled at 19:25 UTC, July 20, 2026. The High Rate Data (HRD) will be enabled at 20:14 UTC, July 20, 2026. Direct Broadcast (DB) users can use the equivalent S-NPP ATMS and VIIRS Community Satellite Processing Package (CSPP) LEO products for operations. 

The OMPS Nadir Mapper (NM) are expected to be approved for operations later this week while the OMPS Nadir Profiler (NP) and Limb Profiler (LP) products are expected to be approved no earlier than late next week following the ingest of additional OMPS SDR LUTs. While OMPS products are available for Direct Broadcast (DB) users, please take caution that OMPS products are not yet approved for operational use. An update notice will be posted once these OMPS products are ready for operational use.
Update#5  Engineering is continuing S-NPP spacecraft recovery efforts. All instruments remain in a safe state and science data remains unavailable.

Update #4: The S-NPP spacecraft entered a non-nominal state at ~14:50 UTC on July 10, 2026. 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 01:30 UTC on July 11, 2026. 


NOAA-21 remains the primary JPSS series spacecraft, and Key Performance Parameters from its instruments continue to be delivered. S-NPP is a Tertiary satellite with no performance and latency requirements.


Update #3: JPSS did not receive SMD Rev. 76180 as well. Data recovery will be attempted during the next successful support.

Update #2: JPSS did not receive SMD Rev. 76179 as well. Data recovery will be attempted during the next successful support.

Update #1: JPSS did not receive SMD Rev. 76178 as well. Data recovery will be attempted during the next successful support.
