Key Impact Points:
- FireSat will detect wildfires as small as 5×5 meters every 20 minutes globally.
- AI-driven high-resolution satellite imagery aims to significantly reduce wildfire damages.
- Google.org contributed $13 million towards the initiative through AI Collaboratives: Wildfires.
Groundbreaking Early Detection
The first satellite of the pioneering FireSat constellation successfully made contact with Earth following its launch from Vandenberg Space Force Base aboard SpaceX’s Transporter-13 mission.
This constellation, which will eventually include more than 50 satellites, aims to revolutionize wildfire detection and tracking by using AI technology to identify fires as small as a classroom.
Currently, wildfire authorities often rely on low-resolution satellite images updated infrequently. FireSat addresses this gap with high-resolution imagery refreshed every 20 minutes, significantly improving early wildfire detection and emergency response effectiveness.
Collaboration for Climate Resilience
FireSat emerged from a collaborative effort among Google Research, Muon Space, Earth Fire Alliance, the Moore Foundation, and wildfire authorities globally.

Juliet Rothenberg, Product Director of Climate AI at Google Research, was motivated by personal experience with wildfire evacuations. She recalls:
“After we evacuated, we constantly stared at satellite imagery to see whether the fire had crossed the road because if it had, we knew our community would burn.”
Recognizing current limitations, Juliet emphasized:
“All we received was updated satellite imagery every 12 hours, while throughout the Bay Area, the sky was red and full of smoke.”
Leveraging AI for Precision
FireSat harnesses AI to rapidly compare new imagery against historical data, considering infrastructure and local weather conditions to accurately detect fires.
Chris Van Arsdale, a FireSat co-founder involved in Google’s climate initiatives, highlighted the urgency of addressing wildfire-induced CO2 emissions:
“We knew we really needed to get a handle on CO2 mitigation for wildfires.”
To validate their AI models, the FireSat team conducted rigorous tests, including aerial sensor trials:
“The first time we used the plane, one of our team members lit a barbeque and a firepit in his backyard so we could fly the plane over and test it,” explained Erica Brand, FireSat project manager. “And the sensors were able to pick it up.”
Future Potential
Beyond immediate emergency response, FireSat contributes significantly to wildfire science and climate action. Juliet Rothenberg notes the broader environmental benefit:
“FireSat is more than just an emergency response tool. It’s also an incredible tool for reducing greenhouse gas emissions. It’s actually really beautiful that the constellation contributes to reducing climate change — while also responding to it.”
FireSat will establish a critical historical record, enhancing our understanding and ability to predict wildfire behavior globally.
