On March 20, NOAA plans to decommission NOAA-17, one of its Polar-Orbiting Operational Environmental Satellites (POES). Known as NOAA M in development, NOAA-17 was launched June 24, 2002. Since launch, NOAA-17 has orbited the Earth approximately 55,000 times. NOAA-17 was a back-up satellite to the Metop-A satellite, whose data NOAA uses operationally as part of the Joint Polar System agreement with the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). While NOAA-17's planned operational life was 3 years, it has soldiered on for over a decade, providing data critical for long-term weather forecast models, climate, and environmental observations. Degrading flight control capabilities and instruments dictated the decision to decommission the satellite this spring. These images show some of the highlights of NOAA-17's career.
