A live stream of the launch will be available on NASA’s website.
The satellites will help improve NOAA forecasts for the three- to seven-day time frame. The data collected from the JPSS is fed into the numerical forecast models to help improve them. The satellites will also collect atmospheric measurements, ground conditions and ocean conditions like vegetation, hurricane intensity and atmospheric moisture.
The JPSS-1 will be launched from Vandenburg Air Force Base in California pending proper flight conditions. The launch was originally scheduled for Tuesday but was delayed until today.
This satellite is a polar orbiting satellite, which means it will orbit the earth from the one pole to the other passing the equator 14 times a day. Full coverage of the planet will be provided then twice a day.
