FireSat
An advanced satellite constellation designed specifically for wildfire detection, monitoring, and response. FireSat will generate an unprecedented dataset on wildfire and its effects on the planet and our communities.
Find FireSat
Built with and for the global
wildfire community.
For decades, firefighters and scientists have relied on satellites designed for other purposes — meaning critical data that arrives too late and a scientific record that hasn’t kept pace with the scale of the challenge. Earth Fire Alliance was formed to close that gap, and together with our technical partner Muon Space, we developed FireSat differently.
Through interviews with 200+ firefighters, incident commanders, and scientists worldwide, we built what the community asked for: frequent, high-resolution data delivered in time to act. The result is a constellation unmatched by any existing or planned satellite system, and a dataset poised to transform how humanity understands, prepares for, and responds to wildfire.
FireSat by the Numbers
Six Bands. One Complete Picture.
FireSat’s 6 multispectral imaging bands work together to reveal fire characteristics at high spatial resolution — simultaneously measuring vegetation condition, surface temperature, and fire dynamics in ways no other space-based system can match.

Two MWIR Bands = Zero Blind Spots
A traditional single midwave infrared (MWIR) band can oversaturate when capturing extremely hot fires — like an overexposed photograph. FireSat has a unique second MWIR band that is tuned down to capture precise temperature measurements at the highest intensities.

1 FireSatOn-orbit flight test validates system architecture and delivers sample datasets.
Initial Operational
Capability
4 FireSats
The first three operational FireSats launched in July 2026, and by year's end will deliver data at least twice daily to Early Adopters across the world's most fire-prone geographies.
Constellation
Buildout
20+ FireSats
Global coverage will expand and data refresh will accelerate to 1 hour or less as additional satellites are deployed in stages.
Full Operational
Capability
~50 FireSats
The complete FireSat constellation will deliver persistent wildfire data with near real-time updates every 20 minutes or less, globally.

Global Wildfire Data for the Public Good
Our vision is to make transformative wildfire data accessible to every fire agency, scientist, and community that needs it—because better data protects lives, communities, and ecosystems.
Fire agencies
Seamlessly integrate FireSat data into existing operational workflows, from early detection to safe response and efficient resource allocation.
Scientists & researchers
Access a first-of-its-kind global wildfire dataset for modeling, analysis, and discovery. FireSat presents new opportunities to understand fire behavior, ecosystem impacts, and climate change.
NGOs
Partner with us to help FireSat data reach under-resourced fire agencies and communities worldwide.
