Flight preview
About this launch
The JPSS constellation of satellites collects global multi-spectral radiometry and other specialized meteorologic, oceanographic, and solar-geophysical data via remote sensing of land, sea, and atmospheric properties. These data support NOAA’s mission for continuous observation of Earth’s environment to understand and predict changes in weather, climate, oceans, and coasts to support the nation’s economy and protect lives and property. NASA uses the instruments aboard the JPSS satellites to continue decades of Earth science research for the betterment of humanity. JPSS-4 carries the NASA Earth Venture mission Libera, an instrument to improve our understanding of trends in Earth’s energy imbalance and our changing climate.
