VANDENBERG AIR FORCE BASE, Calif. — An advanced U.S. weather satellite designed to improve the accuracy of extended forecasts launched early Saturday into polar orbit from California.
The Joint Polar Satellite System-1 lifted off from Vandenberg Air Force Base at 3:47 a.m. Central time atop a United Launch Alliance Delta 2 rocket.
The satellite is the first of four next-generation spacecraft for NASA and the National Oceanic and Atmospheric Administration.
Circling the Earth from pole to pole 14 times a day, the so-called JPSS-1 carries a suite of five instruments intended to make global observations that will improve forecasts of severe weather events three to seven days beforehand.
The satellite also will contribute to near-term weather forecasts, climate and ocean dynamics research, among many other uses.
