NOAA-21 is now fully operational in NOAA’s fleet of polar-orbiting satellites that provide critical data to improve the accuracy of 3-to-7 day weather forecasts – including extreme weather events – and monitor climate change.
The newest satellite in the Joint Polar Satellite System (JPSS) constellation, NOAA-21 launched on November 10, 2022, from Vandenberg Space Force Base in California, joining NOAA-20 and Suomi NPP in orbit. NOAA-21 is flying half an orbit, or 50 minutes, ahead of NOAA-20, with Suomi NPP between them. Each orbit the Earth from the North to the South Pole 14 times a day, providing complete global data coverage twice daily. These satellites take measurements and images that help monitor hurricanes, snowstorms, floods, wildfires, and also the ozone layer.
