Every day and every night, satellites collecting data pass over your house, town, neighborhood, city, and state. These advanced weather satellites make up the Joint Polar Satellite System, which will monitor the Earth from 2011 into the 2030s.

JPSS-2 is scheduled to launch in 2022

JPSS also helps scientists across the world study Earth. The data helps scientists forecast severe weather events such as blizzards, hurricanes, and tornadoes. Using data from JPSS, we know when to bring an umbrella, put on sunscreen, or stay safe from a storm.
