GOES-17 (formerly GOES-S) is the second of the current generation of weather satellites operated by the National Oceanic and Atmospheric Administration (NOAA). The four satellites of the series (GOES-16, -17, -T, and -U) will extend the availability of the GOES (Geostationary Operational Environmental Satellite system) until 2036 for weather forecast and meteorology research. The satellite was built by Lockheed Martin, was based on the A2100A platform, and will have an expected useful life of 15 years (10 years operational after five years of standby as an on-orbit replacement). The satellite was launched on 1 March 2018 and reached geostationary orbit on 12 March 2018. In May 2018, during the satellite's testing phase after launch, a problem was discovered with its primary instrument, the Advanced Baseline Imager. GOES-17 became operational as GOES-West on 12 February 2019. GOES-17 is currently operating alongside GOES-15 but will replace it in July 2019.
