Update #9: All instruments have been offline since Friday, July 29, 2022. Instrument heater activation activities started today, Aug 3, 2022, and will continue throughout the week. The instrument activation sequence is tentatively planned to start next week (August 8-12) and the data product evaluation process is tentatively planned to start during the week of August 15-19. The High Rate Data (HRD) transmitter is powered off. Users who have any questions may directly contact OSPO’s JPSS Data Operations Manager at james.mcnitt@noaa.gov and include the ESPC Help Desk on the cc line (ESPCOperations@noaa.gov).
Update #8: S-NPP transitioned to Mission Point mode on Friday, July 29, 2022. The S-NPP HRD transmitter was powered off on July 29, 2022 at 16:04 UTC. Engineering continues to troubleshoot.
Update #7: As of 17:00 UTC (Aug 01, 2022) there have been no changes in status since the last update as engineering continues to troubleshoot.
Update #6: As of 1730 UTC (Jul 28, 2022), efforts are underway to investigate the S-NPP anomaly and prepare a plan to return the S-NPP spacecraft back to nominal status. These efforts are expected to continue into next week. S-NPP is in sun point (sun-safe) mode and all instruments are in a safe state. Although the HRD transmitter remains on, Direct Broadcast (DB) users are advised that science data is not available. All missed data will not be recoverable. No data is available starting at 16:09 UTC, July 26, 2022.
The NOAA-20 spacecraft (the primary satellite) will continue to provide all the primary JPSS science data needs. Users are advised that when instruments are recovered, products will not be available from PDA until the products are checked out by the instrument and calibration and validation teams.
Users who have any questions may directly contact OSPO’s JPSS Data Operations Manager at james.mcnitt@noaa.gov and include the ESPC Help Desk on the cc line (ESPCOperations@noaa.gov).
Update #5: There have been no changes in status since the last update as engineering continues to troubleshoot. An update to this notice will be posted as new information becomes available.
Update #4: After further investigation, the SNPP spacecraft entered a non-nominal state at ~16:24:49 UTC on Jul 26, 2022, after which all SMD and telemetry data was inaccessible. While the root cause continues to be investigated, subsequent contacts have confirmed the spacecraft and all instruments are currently in a safe mode state. Engineering will continue to restore all instruments and science data to an operational state once a plan forward has been determined. All missed data will not be recoverable. The NOAA-20 spacecraft will continue to provide all the primary JPSS science data needs. An update to this notice will be posted by 15:00 UTC on Jul 27, 2022.
Update #3: IDPS is still not receiving NPP SMD data. The problem is still being investigated.
Update #2: IDPS is still not receiving NPP SMD data. The problem is still being investigated.
Update #1: IDPS is still not receiving NPP SMD data due to a possible antenna issue. The problem is being investigated.
