| PACE_HARP2 | Science Operations | No Impact | Feb 21 2026 | Feb 21 2026 | Solar Calibration |
| PACE | Safe Mode | No Data | Feb 9 2026 | Feb 11 2026 | PACE entered safehold Monday February 9, 2026, at 040/19:10:42 UTC (02:10:42 PM EDT), which was the end of the scheduled Earth limb view activity. The safehold was triggered by a detection of excessive momentum. The origin was a human error during the ground testing of the activity that was done before the command load was uplinked. By Wednesday Feb 11th at 042/21:25 UTC (4:25 PM EDT) all three instruments were recovered to nominal mission science operations. Each instrument lost about 2 days worth of science data. |

| PACE_OCI | Anomaly | No Data | Feb 1 2026 | Feb 1 2026 | PACE OCI encountered a memory scrub-induced processor reset and entered safemode at approximately 2026/032 04:24 UTC. OCI science data collection stopped at 04:24:36 UTC and resumed at 22:02:46 UTC. As a result, the lunar Calibration at -7 degree phase scheduled for 2026-032-09:52:23 was not completed. |
