The Joint Polar Satellite System (JPSS) is the restructured civilian portion of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) that will make afternoon observations as it orbits Earth. The system includes the satellites and sensors supporting civil weather and climate measurements and a shared ground infrastructure with the Department of Defense weather satellite system. JPSS-2 successfully lifted off from Vandenberg Space Force Base on Nov. 10, 2022, at 1:49 a.m. PST and was renamed NOAA-21.
