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.

[4][5] 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),[1] from the Kennedy Space Center in Florida, United States.

Using Falcon Heavy saves propellant on the spacecraft, allowing longer life.

The redesign of the loop heat pipe to prevent an anomaly, as seen in GOES-17, is not expected to delay the launch as it did with GOES-T.[6] GOES-U 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.
