Atlas V to Launch Game-Changing ‘GOES-S’ Today for Unprecedented Meteorology Across Western U.S.

A United Launch Alliance Atlas V rocket on Space Launch Complex 41 at Cape Canaveral Air Force Station. The launch vehicle will send the National Oceanic and Atmospheric Administration’s, or NOAA’s, Geostationary Operational Environmental Satellite, or GOES-S, into orbit. The GOES series is designed to significantly improve the detection and observation of environmental phenomena […]
