The National Oceanic and Atmospheric Administration (NOAA) is nearing the conclusion of its long-standing Polar Operational Environmental Satellites (POES) program, a constellation that has provided critical weather and environmental data for decades. As of today, the remaining satellites—NOAA-15 and NOAA-19—are on the cusp of decommissioning, marking the transition to newer, more advanced systems like the Joint Polar Satellite System (JPSS). However, recent anomalies have introduced delays, extending the operational life of these aging spacecraft just a bit longer.
Launched between 1998 and 2009, the POES satellites have been instrumental in global weather forecasting, climate monitoring, and disaster response. NOAA-15, the oldest in the trio, was launched in May 1998 and has far exceeded its expected lifespan, continuing to transmit data despite technical challenges. NOAA-18 followed in 2005, and NOAA-19 in 2009. Together, they orbited Earth in polar paths, capturing imagery and measurements used for everything from storm tracking to agricultural planning.
The decommissioning process began earlier this year. NOAA-18 was officially retired on June 6, 2025, following a significant failure in its S-band transmitter on May 31. This decision was part of NOAA’s strategy to responsibly manage on-orbit assets, especially as newer satellites take over. On June 16, 2025, NOAA ceased delivery of all POES data to users, suspending operational products to facilitate the shift to JPSS platforms like NOAA-20 and JPSS-2, which offer higher resolution and more reliable data.
Originally, NOAA-15 was slated for decommissioning on August 12, 2025, with NOAA-19 following on August 19. But in a last-minute update, NOAA operations announced a delay for NOAA-15 to the week of August 18 due to an anomaly detected on NOAA-19 yesterday. This extension allows for continued limited services, such as High Resolution Picture Transmission (HRPT), which amateur radio enthusiasts and satellite trackers have relied on. As of this morning, users were still receiving precipitation images from NOAA-15, highlighting its resilience even in its final days.
The phase-out has not been without broader implications. In April, NOAA announced the discontinuation of Space Environment Monitor-2 (SEM-2) data collection from POES satellites in preparation for decommissioning, affecting space weather monitoring. Additionally, there were initial concerns about the Defense Meteorological Satellite Program (DMSP), a related military system, being phased out by July 31, but updates confirmed a one-year delay, ensuring continued data flow for weather forecasting during hurricane season.
Social media and online communities, particularly on Reddit’s r/amateursatellites and r/RTLSDR forums, have been abuzz with reactions. Enthusiasts are sharing memories of decoding satellite signals, with posts like “Let’s remember our moments with NOAA satellites” evoking nostalgia for the era of analog APT transmissions. One user lamented, “The date is 10 August UTC, and only 2 days left till the shutdown of last legacy POES SATs begins,” while others circulated petitions to save NOAA-15 and NOAA-19, arguing for their continued utility in amateur radio and education. Discussions also clarified misconceptions, such as early fears that all NOAA satellites were ending immediately, with users confirming that transmissions persisted post-data suspension.
On X (formerly Twitter), satellite tracking accounts like @DundeeSat and @carlreinemann have provided real-time updates on the delays, underscoring the community’s close monitoring. Broader conversations tied the decommissioning to political debates on funding cuts to NOAA, though the agency emphasizes that the move is driven by technological advancement rather than budget constraints.
As POES fades into history, NOAA assures that the JPSS series will fill the void with enhanced capabilities, including better imagery for severe weather prediction. The end of POES not only closes a chapter in satellite meteorology but also highlights the evolution of space-based observation, ensuring more accurate forecasts for years to come. Enthusiasts are encouraged to capture final passes while they can, as these venerable satellites prepare for their well-earned retirement.
