Bezos-backed FireSat network to track global wildfires within 20 minutes

FireSat, a new satellite constellation purpose-built for global wildfire detection, is set to transform how emergency services respond to blazes. Backed by a $26 million investment from Jeff Bezos through the Bezos Earth Fund, the program launched in July 2026. Developed for the Earth Fire Alliance by space systems company Muon Space, the network utilizes advanced infrared satellites capable of detecting fires as small as a 15-foot by 15-foot beach bonfire. The system aims to provide near real-time data to fire agencies and scientists to prevent small flames from escalating into major disasters.

The program has already demonstrated its capabilities through a Protoflight mission. A demonstration satellite sent into orbit in March 2025 successfully detected a small roadside fire in Oregon in October that had been missed by other space-based monitoring systems. According to EFA lead scientist Michael Falkowski, the fire was started by trailer chains being dragged on a highway. Since its July launch, the satellites also collected data on the Big Grass Fire, which had consumed 290,000 acres—an area the size of Los Angeles—at the time of detection on July 28.

By 2029, the FireSat constellation is expected to include more than 20 satellites, providing hourly global revisits. The Bezos Earth Fund projects this coverage will reduce the amount of US land burned annually by 1.3 million acres, protect 3,500 homes, and prevent 21.9 million tons of carbon emissions. When fully operational in the early 2030s with approximately 50 satellites in low-Earth orbit, the system will monitor every point on the planet every 20 minutes or less. Lauren Sánchez Bezos, Vice Chair of the Bezos Earth Fund, noted that the technology aims to provide the faster response times necessary to safeguard communities.

Beyond detection, the initiative focuses on long-term climate impact and research. Tom Taylor, President and CEO of the Bezos Earth Fund, stated that the innovation helps address the challenges of uncontrolled wildfires to preserve forests and biodiversity. Early adopters of the FireSat data already include fire organizations in the United States—specifically California, Colorado, Oregon, and Texas—as well as agencies in Africa, Australia, and Portugal. The project aims to integrate satellite data directly into firefighting operations and global wildfire modeling within the next five to ten years to improve resilience strategies.

What to watch: The expansion of the satellite network to reach hourly global coverage by 2029.
