Mission

The Geostationary Operational Environmental Satellite-U (GOES-U) is the fourth of the next generation of geostationary weather satellites, known as the GOES-R series. The four satellites of the series provide advanced imaging with increased spatial resolution and faster coverage for more accurate forecasts, real-time mapping of lightning activity, and improved monitoring of solar activity. Once GOES-U reaches orbit, it will be renamed GOES-19.
