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), [1] 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]

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 20 March 2025, GOES-19's CCOR has found 27 comets. [12]

The faint comet 3I/ATLAS is observable from 18–24 October 2025 with GOES-19 as the satellite can see objects down to magnitude 12. [13]
