NOAA is planning a two-satellite operational GeoXO constellation, plus two replacement satellites. Each spacecraft will carry an imager and a sounder.
The first GeoXO satellite, scheduled for launch in 2032, is planned to carry the GOES-R-era Advanced Baseline Imager (ABI) and a new GeoXO Sounder instrument.
The remaining GeoXO satellites, planned for launch in 2034, 2039 and 2043, will carry the new GeoXO Imager and GeoXO Sounder.
GeoXO Spacecraft Status
On June 18, 2024, NASA selected Lockheed Martin to develop NOAA’s GeoXO spacecraft. The contract scope includes the tasks necessary to design, analyze, develop, fabricate, integrate, test, evaluate, and support launch of the GeoXO satellites; provide engineering development units; supply and maintain the ground support equipment and simulators; and support mission operations.
The GeoXO spacecraft completed its Preliminary Design Review in December 2025. The spacecraft team is proceeding with detailed design.
GeoXO Instruments
GeoXO includes a visible/infrared imager and a hyperspectral infrared sounder to meet the observational needs of NOAA’s weather mission and the satellite data user community.
Industry Collaboration
NOAA and NASA are working with industry partners to develop the instruments and spacecraft that will deliver GeoXO's observations.
