The Bezos Earth Fund has committed $26m to support Earth Fire Alliance’s FireSat programme, marking the largest philanthropic investment ever made in wildfire detection technology.
The funding will help deploy the first three operational FireSat satellites, which are scheduled to launch this summer and begin delivering enhanced wildfire monitoring capabilities across some of the world’s most vulnerable regions.
The investment comes as wildfires continue to intensify globally, causing widespread environmental damage, threatening communities, and contributing significantly to annual tree cover loss.
The new funding is expected to accelerate the deployment of a satellite constellation specifically designed to improve wildfire detection and provide earlier warnings to emergency responders.
Once operational, the initial FireSat satellites will monitor key fire-prone areas at least twice each day, including the Amazon Basin. The long-term goal is to create a global monitoring system capable of identifying emerging fires before they develop into large-scale disasters, helping reduce environmental and economic losses.
Bezos Earth Fund president and chief executive officer, Tom Taylor explained: “At the Bezos Earth Fund, we’re focused on supporting innovation that helps solve some of the hardest challenges in climate and nature, and breakthrough technology that addresses the challenges with uncontrolled wildfires is an important area that our funding can help move forward, faster.
“Advancing detection and prevention technologies such as FireSat have incredible potential to better protect homes and communities, preserve forests and biodiversity, and reduce emissions, and we’re excited to be working together on these areas.”
Wildfires are becoming more severe as climate change creates hotter and drier conditions across many regions. While fire plays a natural role in maintaining the health of certain ecosystems, changing weather patterns are increasing the likelihood that manageable fires escalate into destructive events.
Beyond the immediate threat to homes and infrastructure, large wildfires release substantial amounts of carbon dioxide and generate smoke that can travel hundreds or even thousands of miles, affecting air quality far from the source.
These impacts have heightened demand for faster and more reliable wildfire detection systems. Developed by Earth Fire Alliance in partnership with space systems company Muon Space, FireSat is the first satellite constellation built exclusively for wildfire detection.
The system uses advanced infrared sensing technology to identify small fires shortly after ignition and provide near realtime information to fire agencies and researchers. The satellites are designed to detect fires as small as a beach bonfire, enabling authorities to respond before flames spread uncontrollably.
High-resolution data collected by the constellation will support firefighting operations while also improving scientific understanding of fire behaviour and ecosystem impacts. Global coverage planned by 2029 The FireSat network is expected to expand rapidly over the coming years.
By 2029, the constellation is projected to detect fires measuring as little as 15 feet by 15 feet anywhere on Earth within one hour of ignition.
