GOES-19 (designatedGOES-U prior to reaching geostationary orbit) is aweather satellite, the fourth and last of theGOES-R series of satellites operated by theNational Oceanic and Atmospheric Administration (NOAA). The GOES-R series will extend the availability of theGeostationary Operational Environmental Satellite (GOES) system until 2036. The satellite is built byLockheed Martin, based on theA2100 platform.[5][6] The satellite was placed into service as the GOES-East position andGOES-16 was stored as backup on April 7, 2025.[7]
The satellite was successfully launched into space atop aSpaceXFalcon Heavy rocket on 25 June 2024 at 21:26 UTC (5:26 pm EDT local time at the launch site),[2] from theKennedy Space Center inFlorida, United States. The redesign of theloop heat pipe to prevent ananomaly, as seen inGOES-17, was not expected to delay the launch as withGOES-T.[8]
GOES-19 also carries a copy of theNaval Research Laboratory's CompactCORonagraph (CCOR) instrument which, along with the CCOR planned forSpace Weather Follow On-Lagrange 1 (SWFO-L1), will allow continued monitoring ofsolar wind after the retirement of theNASA-ESASOHO 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]
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 comet3I/ATLAS is observable from 18–24 October 2025 with GOES-19 as the satellite can see objects down tomagnitude 12.[13]
