The Joint Polar Satellite System-1 (JPSS-1), the first in a new series of four highly advanced National Oceanic and Atmospheric Administration (NOAA) polar-orbiting satellites, which will help increase weather forecast accuracy from three to seven days out, is scheduled to launch on Friday, Nov. 10 from Vandenberg Air Force Base, California.
Liftoff aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2W is targeted for 1:47 a.m. PST (4:47 a.m. EST) at the opening of a 65-second launch window. JPSS, a collaborative effort between NOAA and NASA, represents significant technological and scientific advancements in observations used for severe weather prediction and environmental monitoring.
JPSS satellites circle Earth from pole-to-pole and cross the equator 14 times daily providing full global coverage twice a day. Polar satellites are considered the backbone of the global observing system.
NOAA’s National Weather Service uses JPSS data as critical input for numerical forecast models, providing the basis for mid-range forecasts. These forecasts enable emergency managers to make timely decisions to protect American lives and property, including early warnings and evacuations.
