A new generation of satellites powered by artificial intelligence is set to transform how wildfires are detected and monitored, offering emergency responders faster and more accurate information to combat devastating blazes worldwide.
The initiative, known as FireSat, is being developed by the nonprofit Earth Fire Alliance in partnership with space technology company Muon Space, with technical support from Google Research.
Unlike existing satellite systems that often provide low-resolution images or update only a few times each day, FireSat is designed to detect fires as small as five by five metres and deliver updated imagery every 20 minutes or less once the full satellite constellation is operational.
The system combines high-resolution multispectral infrared imagery with artificial intelligence to identify emerging fires in near real time.
AI analyzes current satellite images against thousands of previous observations while factoring in local weather conditions and other environmental data to accurately determine whether a fire is present.
Developers say the technology will significantly improve situational awareness for firefighters and disaster response agencies, enabling quicker intervention before small fires grow into large-scale disasters.
The FireSat prototype, known as Protoflight, was launched aboard a SpaceX Transporter-13 mission from Vandenberg Space Force Base in California in March 2025. Since then, it has successfully detected fires of varying sizes across five continents, including small fires that existing satellite systems failed to identify.
The first three operational FireSat satellites are scheduled for launch in the summer of 2026, with additional satellites to be deployed over the coming years to establish a global monitoring network.
Beyond emergency response, researchers say FireSat data will support scientific studies on wildfire behaviour, ecosystem recovery and climate resilience. The information is also expected to strengthen AI models used to predict fire spread and assess future wildfire risks.
To support the initiative, Google.org has committed more than US$15 million in funding, alongside contributions from the Gordon and Betty Moore Foundation and the Bezos Earth Fund.
Developers believe FireSat will mark a major breakthrough in global wildfire monitoring, helping protect lives, ecosystems and communities increasingly threatened by climate-driven wildfires.
