GOES-19
GOES-19 is a weather satellite, the fourth and last of the GOES-R series of satellites operated by the National Oceanic and Atmospheric Administration. The GOES-R series will extend the availability of the Geostationary Operational Environmental Satellite system until 2036. The satellite is built by Lockheed Martin, based on the A2100 platform. The satellite was placed into service as the GOES-East position and GOES-16 was stored as backup on April 7, 2025.
Launch
The satellite was successfully launched into space atop a SpaceX Falcon Heavy rocket on 25 June 2024 at 21:26UTC, 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.GOES-19 also carries a copy of the Naval Research Laboratory's Compact CORonagraph instrument which, along with the CCOR planned for Space Weather Follow On-Lagrange 1, will allow continued monitoring of solar wind after the retirement of the NASA-ESA SOHO satellite in 2025.
GOES-19 has a dry mass of and a fueled mass of.
Comet discoveries through CCOR
The CCOR instrument carried aboard GOES-19 has allowed for the discovery of several sungrazer comets by researchers analyzing CCOR imagery. As of 28 May 2025, GOES-19's CCOR has found 47 comets.The faint comet 3I/ATLAS was observable from 18–24 October 2025 with GOES-19 as the satellite can see objects down to magnitude 12.
