Update #2: The investigation of the Ka-Transmitter anomaly is still ongoing. X-Band High Rate Data (HRD) received over Svalbard are being used to backfill SMD on a best-case basis.


Update #1: After soft and hard reset, there are still anomalous errors with the Ka-Transmitter with NOAA-21 (JPSS-2). All Stored Mission Data (SMD) Playback attempts are on hold. Anomaly response is ongoing to identify and resolve the root cause of the Ka-Transmitter anomaly.  Please note that NOAA-21 (JPSS-2) remains in Post Launch Testing (PLT) by the Mission Operations Support Team (MOST) and is not in operational service during this early checkout phase. ATMS data outage notifications will be limited to business hours only until Handover occurs in February 2023.
