GOES-U mission insignia

GOES-19 (designated GOES-U prior to reaching geostationary orbit) is a weather satellite, the fourth and last of the GOES-R series of satellites operated by the National Oceanic and Atmospheric Administration (NOAA). The GOES-R series will extend the availability of the Geostationary Operational Environmental Satellite (GOES) system until 2036. The satellite is built by Lockheed Martin, based on the A2100 platform.[5][6] The satellite was placed into service as the GOES-East position and GOES-16 was stored as backup on April 7, 2025.[7]

Launch

The satellite was successfully launched into space atop a SpaceX Falcon Heavy rocket on 25 June 2024 at 21:26 UTC (5:26 pm EDT local time at the launch site),[2] from the Kennedy Space Center in Florida, United States. The redesign of the loop heat pipe to prevent an anomaly, as seen in GOES-17, was not expected to delay the launch as with GOES-T.[8]

GOES-19 also carries a copy of the Naval Research Laboratory's Compact CORonagraph (CCOR) instrument which, along with the CCOR planned for Space Weather Follow On-Lagrange 1 (SWFO-L1), will allow continued monitoring of solar wind after the retirement of the NASA-ESA SOHO satellite in 2025.[9][10]

GOES-19 has a dry mass of 2,925 kg (6,449 lb) and a fueled mass of 5,000 kg (11,023 lb).[11]
