How a New Satellite Constellation Is Rewriting the Rules of Early Wildfire Detection
The Earth Fire Alliance has launched the first three satellites of its FireSat constellation, designed to detect wildfires in near real-time. The project aims to deploy 50 satellites to provide continuous global monitoring and early intervention capabilities.
Why it matters
This technology could significantly reduce the scale of wildfire disasters by enabling firefighters to respond to ignitions before they escalate.
Earth Fire Alliance is a winner of the 2026 Gizmodo Science Fair for developing a satellite constellation dedicated to the early detection of potentially dangerous wildfires.
For years, firefighters and scientists have watched wildfires from space using satellites built to do many things—but not specifically to find fires. By the time those satellites detect a fire and send the data back to Earth, a tiny blaze can already have become a fast-moving wildfire. The FireSat constellation is designed to change that: a network of satellites built specifically to spot fires early, providing near real-time data that could give firefighters a crucial window to act before a small flame turns into a major disaster.
Can a satellite constellation be used to detect small, cool ignitions from space before they escalate and, in turn, generate a global dataset that can help scientists better understand the behavior of fire?
