| PACE_SPEXONE | SEU Command Processor and Formatter Reset | No Data | Mar 12 2026 | Mar 12 2026 | SPEXOne experienced a Fail Counter aggregation anomaly. The SPEXOne team reported it was potentially due to an SEU-induced ICU-FPGA problem over the SAA that corrupted the connection to the DEM SpaceWire. The instrument was recovered after an ICU power cycle and DEM comms connection restored, which supported the SPEXOne team's initial assessments. The last full science product was taken at 2026-03-12T04:31:45, and after recovery, data collection resumed at 2026-03-12T13:37:11. |

| PACE | Anomaly | Reduced Quality | Mar 1 2026 | Mar 2 2026 | A scheduling error caused duplicate subsolar tilt changes at 00:00 Monday during the weekly ATS load transition. A 3-second orbit timing shift moved the subsolar point across the day boundary, triggering both negative (old load) and positive (new load) staggers. The toggling command resulted in aft tilt for half an orbit, causing excessive glint. The following eclipse tilt change corrected the phase. |
| PACE | Safe Mode | No Data | Mar 2 2026 | Mar 2 2026 | PACE experience a processor reset (MBE) and entered safemode around 2026-061-05:18:23 and returned to nominal operations at 26-061-23:16:03 UTC. Science data collection resumed just after 2026-03-03T00:10:49. OCI and SPEXone lost roughly 18 hours of data, and HARP2 lost roughly 21 hours of data. |
