Topic: S-NPP CrIS End of Operational Use 

Date/Time Issued: February 11, 2026 18:00 UTC

Product(s) or Data Impacted: All S-NPP CrIS Products

Date/Time Initial Impact: December 23, 2025 07:00:24 UTC

Date/Time of Expected End: N/A

Length of Outage: Permanent - Decomissioning

Details/Specifics: 

The S-NPP CrIS instrument experienced a single event upset on December 23, 2025 at 11:36:40 UTC which rendered the Scene Selection Module (SSM) inoperable.  After repeated attempts to recover the SSM, engineers were unable to restore the S-NPP CrIS instrument to an operational state. To date, the SSM remains in an anomalous state. Given that the S-NPP CrIS instrument is operating well beyond its Design Life, and is tertiary within the JPSS Constellation and has no assigned performance or latency Requirements, the Director of the NESDIS Office of Satellite and Product Operations (OSPO) has approved the recommendation to suspend recovery efforts. This decision permanently ends the operational use of the S-NPP CrIS Instrument.
