NOAA-20, designated JPSS-1 prior to launch, is the first of the United States National Oceanic and Atmospheric Administration's latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites called the Joint Polar Satellite System. NOAA-20 was launched on November 18, 2017 and joined the Suomi National Polar-orbiting Partnership satellite in the same orbit. NOAA-20 operates about 50 minutes ahead of Suomi NPP, allowing important overlap in observational coverage. Circling the Earth from pole-to-pole, it crosses the equator about 14 times daily, providing full global coverage twice a day. This will give meteorologists information on "atmospheric temperature and moisture, clouds, sea-surface temperature, ocean color, sea ice cover, volcanic ash, and fire detection" so as to enhance weather forecasting including hurricane tracking, post-hurricane recovery by detailing storm damage and mapping of power outages. The project incorporates five instruments, and these are substantially upgraded since previous satellite equipment. The project's greater-detailed observations will provide better predictions and emphasize climate behavior in cases like El Niño and La Nina. The project's satellite bus and Ozone Mapping and Profiler equipment, was designed by Ball Aerospace. The Visible Infrared Imaging Radiometer Suite and the Common Ground System were built by Raytheon, and the Cross-track Infrared Sounder was by Harris. The Advanced Technology Microwave Sounder and the Clouds and the Earth’s Radiant Energy System instrument were built by Northrop Grumman Aerospace Systems.
