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 to continuously observe Earth’s environment to understand and predict changes in weather, climate, oceans, and coasts, 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. When launched, JPSS-4 will carry the NASA Earth Venture mission Libera, an instrument that will improve our understanding of trends in Earth’s energy imbalance and our changing climate.

NASA and NOAA's contract with SpaceX for this launch is a firm-fixed-price contract with a value of approximately $112.7 million, which includes launch services and other mission-related costs.
