Made possible by public-private-philanthropic partnerships, this milestone launch advances FireSat toward a near real-time, global view of wildfire
LOMPOC, CALIF., USA — July 7, 2026 — Earth Fire Alliance (EFA), the global nonprofit illuminating the world’s fires, today announced the launch of its first three operational FireSat satellites, marking a transformative milestone in how the world will detect, respond to, and recover from wildfire. The satellites, designed and built by EFA founding technical partner Muon Space, launched from Vandenberg Space Force Base in California as part of SpaceX’s Transporter-17 rideshare mission. The launch marks Initial Operational Capability for the FireSat constellation, an advanced, multispectral satellite system purpose-built to address the global wildfire challenge.
This milestone is the shared achievement of EFA’s growing, global coalition of mission-aligned funders, partners, and Early Adopters united around common goals: to build the technological infrastructure necessary to identify, monitor, and understand Earth’s wildfires; and to deliver critical data to the firefighters and scientists who need it most.
Realizing these goals is made possible by EFA’s philanthropic supporters, including the Fonds pour la Terre de Bezos, Google.org, le 29. Fondation Gordon et Betty Moore, and additional funders. FireSat’s advanced design was shaped in collaboration with hundreds of firefighters and fire scientists to ensure its capabilities meet their real-world needs.
Built on Radical Collaboration
EFA operates on a public-private-philanthropic partnership, or “P4,” model that unites commercial innovation, end-user co-development, and philanthropic and government investment to maximize resources, innovate rapidly, and ensure sustainable growth.
“This milestone is a direct result of the P4 philosophy at the heart of everything we do,” said Brian Collins, Executive Director of Earth Fire Alliance. “No single government, sector, or organization can solve the wildfire crisis alone. FireSat is the result of radical collaboration: visionary philanthropists who invested early; Muon Space, which designed and built these spacecraft and their instruments; and the fire agencies and scientists whose early input helped tailor the system specifically for firefighting. These three satellites prove that when public and private sectors unite, we can deliver breakthrough technology to protect our planet.”
Today’s launch builds on the FireSat protoflight, which launched in March 2025 and has already validated the system’s breakthrough capabilities. The protoflight has detected fires invisible to existing satellites, including small, low-intensity blazes in their earliest stages. These three satellites carry that proven architecture forward into operational service.
“FireSat has already proven that a satellite built specifically for wildfire can detect fires earlier and smaller than was previously possible. With these satellites, we turn that proof into an operational service–the start of dedicated coverage that fire managers can count on day after day,” said Jonny Dyer, CEO of Muon Space. “This is the foundation of the constellation we set out to build in partnership with Earth Fire Alliance, and every satellite we add brings us closer to giving the people who fight and study fires a clear, near real-time picture of every fire on Earth.”
What’s Next for FireSat
Following today’s launch, the three satellites will undergo approximately three months of testing and checkout ahead of nominal operations:
- Q4 2026: Operational FireSat data will reach EFA’s Early Adopters—fire agencies and scientists across the world’s most fire-prone geographies—at least twice daily.
- 2027-2028: Data availability will expand throughout 2027 to support fire science and wildfire resilience activities as well as emerging commercial applications, with global access anticipated by 2028.
- 2029+: As additional satellites join the constellation, EFA’s next impact target is a global revisit rate of one hour or less by 2029, followed by an ultimate goal of 20 minutes or less in the early 2030s.
- Beyond FireSat: EFA is also building two emerging programs: FireImpact, which will translate FireSat’s global dataset into actionable scientific knowledge; and FireConnect, which will connect that data to local action and resilience-building in communities worldwide.
Together, FireSat, FireImpact, and FireConnect will form a through line from space to communities on the ground—generating the world’s most complete wildfire dataset and putting it to work where it’s needed most.
À propos de l'Alliance Terre Feu
Earth Fire Alliance (EFA) is a global nonprofit coalition building the technological infrastructure the world needs to detect, monitor, and understand fire—and delivering critical data to the firefighters, scientists, and communities who need it most. Le programme phare de l'EFA, FireSat, est la première constellation de satellites conçue spécifiquement pour relever le défi des incendies de forêt : générer un ensemble de données sans précédent sur le feu et ses effets sur les personnes et la planète. L'EFA collabore avec des agences opérationnelles, des scientifiques et des technologues à travers les continents pour rendre les données sur le feu accessibles, exploitables et disponibles pour le bien public.
