Update 8/1/2025: NOAA has completed End of Life (EOL) testing activities for NOAA-15 and NOAA-19 and will commence the decommission process shortly. These two remaining satellites in the NOAA Polar Operational Environmental Satellites (POES) Constellation are far beyond their primary mission design life. All have incurred subsystem and instrument degradation or failures and have entered a "twilight phase" where failure modes are increasingly likely. As a reminder, NOAA-18 was decommissioned on June 6, 2025 at 1740 UTC due to an unrecoverable failure to the S-Band transmitter. The remaining satellites in the legacy POES constellation will be decommissioned as follows: NOAA-15 on August 12, 2025 and NOAA-19 on August 19, 2025.
Update 8/20/2025: Please be advised that NOAA-15 and NOAA-19 have been decommissioned. NOAA-15 was decommissioned on August 19, 2025 at 20:37 UTC and NOAA-19 was decommissioned on August 13, 2025 at 16:55 UTC.
