California has taken a giant leap in wildfire detection with the launch of the first three FireSat satellites from Vandenberg Space Force Base in Santa Barbara County. This purpose-built system, announced by Governor Gavin Newsom on July 7, will provide near real-time monitoring of wildfires across the state and eventually the globe. The satellites promise to give firefighters critical extra minutes to respond to blazes before they escalate into megafires. This is the first time a satellite system has been designed with the explicit intention of detecting wildfires. The satellites were carried into orbit aboard a SpaceX Falcon 9 rocket as part of the company’s Transporter-17 Mission.
Governor Newsom emphasized the importance of the launch, stating: "FireSat is about more than satellites in the sky; it’s about protecting families, firefighters, and communities that live with the fear of wildfire every summer. While the Trump administration walks away from its responsibility to keep people safe, California is choosing leadership, innovation, and action. We are proving that when we invest in science, in technology, and in one another, we can turn the tide on these fires and build a safer, more resilient future."
The FireSat satellites, built by Mountain View-based Muon Space, use advanced multi-spectral infrared sensors to detect heat signatures. They can spot fires as small as a schoolyard (5x5 meters) and differentiate between intense flames and cooler, smoldering combustion—a key capability for understanding fire behavior and air quality impacts. According to Michael Falkowski, lead scientist at Earth Fire Alliance, the satellites can detect a fire the size of a shipping container and distinguish between hot, fast-burning fires and cooler ones that produce more harmful smoke. Falkowski noted that fires burning at low temperature produce more harmful gases than hot fires, similar to a campfire: when burning hot with bright flames, there is relatively little smoke, but when smoldering, it produces lots of thick, white or gray smoke. Wildfires work the same way—a hot, fast-burning fire has enough oxygen and heat to burn with more complete combustion, producing less smoke for every pound of wood burned.
This next phase builds directly on the momentum established last year when FireSat’s pilot satellite reached orbit. That mission successfully demonstrated the potential of the underlying sensor technology designed to detect early-stage wildfires as small as 5x5 meters. The pilot has already spotted small, low-intensity blazes invisible to existing satellites, and these three new orbiters carry that proven architecture directly into the growing network. For example, the protoflight satellite delivered images of a small roadside fire in Oregon that was undetected by existing satellites.
Google and its partners use AI to compare each new image against thousands of previous observations, factoring in local weather and other conditions to reliably determine whether a fire is present. This AI-driven approach enhances the system's accuracy and reduces false alarms.
The three satellites are the first of a planned constellation of over 50 satellites by 2030. Once fully deployed, the network will cover the entire planet every 20 minutes, providing continuous high-resolution imagery. This marks a major upgrade from existing NOAA satellites, which can only detect fires within a 1,230-foot square, while FireSat can identify fires just 16 feet across. By 2029, the constellation will have more satellites delivering data at an hourly rate globally, according to Earth Fire Alliance. With the current three satellites, every fire-prone region will be imaged a minimum of twice every 24 hours, and the entire state of California falls within FireSat’s coverage, spanning the Sierra Nevada to Southern California, coastal areas and everywhere in between.
Each satellite is about the size of a dishwasher or washing machine, weighing approximately 250 pounds, and they unfold in orbit, according to Muon Space CEO Jonny Dyer.
Following liftoff, the satellites will undergo a three‑month commissioning and calibration period before beginning operational data delivery.
California has been at the forefront of wildfire technology, and FireSat builds on existing efforts like the ALERTCalifornia camera network (over 1,200 cameras) and AI-powered detection systems. In 2025, ALERTCalifornia detected fires before any 911 calls 51% of the time, according to CAL FIRE’s Phillip SeLegue. FireSat will complement these ground-based tools by providing overhead visibility through smoke and during nighttime hours. CAL FIRE played a foundational role in developing the FireSat concept, conducting early testing and evaluation. Earth Fire Alliance will provide data from these first three satellites in the next few months to CAL FIRE and fire agencies in Oregon, Texas, Australia and Portugal. CAL FIRE will share it with Southern California fire agencies, including the Los Angeles and Los Angeles County fire departments. The network will also turn its sensors on in the Amazon Basin for the Brazilian nonprofit Amazon Environmental Research Institute. Other early adopters include firefighting and fire prevention agencies in Colorado, Australia and Portugal.
Travis Medema, chief deputy for the Oregon State Fire Marshall, said his office will use FireSat to plan escape routes and monitor fires. “If we can fight these when they are small, we feel we will be more efficient and can protect Oregonians,” he said.
Keith Masback of Earth Fire Alliance described the system as "absolutely game-changing," noting that during recent destructive wildfires, firefighters were "fighting blind at times" due to smoke limiting visibility. FireSat can see through smoke to provide critical information on where the fire is hot, cold, moving, or already burned. Craig Clements of the Wildfire Research Center in San Jose added that the higher resolution will allow researchers to see the firefront shape and how it evolves through forests and communities.
Falkowski, who joined Earth Fire Alliance last year from NASA where he was an earth science program manager running the agency’s fire science program, said the new FireSat satellites are a big improvement over existing ones because they will be able to see smaller fires with better resolution and distinguish low-intensity "cool" fires from high-intensity hot ones. "The satellites are really designed to measure fire across the entire temperature profile, so we can see cool fires all the way up to really hot fires," he said. That kind of granular information is important for emergency responders in the field and planners who make decisions about calling for extra help or ordering evacuations.
FireSat will help incident commanders get better information more quickly, and, unlike fire-spotting aircraft, the satellites can linger over a fire for days or weeks and aren’t hampered by high winds or smoke.
“FireSat represents a fundamental shift in how we detect, understand, and respond to wildfire,” said Earth Fire Alliance board member Chris Anthony in a statement. “This launch reflects years of collaboration among fire agencies, Earth Fire Alliance, philanthropy, and technology partners and marks the beginning of a new era in global wildfire intelligence.”
CAL FIRE Director and Fire Chief Joe Tyler also commented: "The FireSat launch marks a transformative step toward space‑enabled wildfire intelligence, strengthening California’s resilience and demonstrating the power of global collaboration in confronting increasingly complex fire years."
Muon Space CEO Jonny Dyer and Earth Fire Alliance Executive Director Brian Collins discussed the milestone on NBC News, highlighting how the growing constellation will help reshape the way we detect, understand, and respond to wildfires. FireSat will deliver global wildfire monitoring, providing more timely, actionable information to strengthen response efforts, improve situational awareness, and help make communities around the world safer.
Wildfires have become increasingly destructive in California, with over 3,200 wildfires and 1,880 structure fires reported so far this year. Since the start of the year, wildfires have scorched a combined 85,665 acres in California as of July 6, according to Cal Fire and the U.S. Forest Service. It’s several thousand acres more compared to a five-year average of the same period. The state has invested heavily in prevention and response, including a $2.5 billion wildfire resilience program and a fire protection budget increase from $2 billion to $3.8 billion. Previous efforts include autonomous firefighting helicopters and real-time fire modeling, but space-based detection has been a missing piece until now.
This milestone is a testament to what is possible when tech companies, nonprofits, philanthropy, and the private sector unite under a single mission. To help kickstart this work, Google.org has provided over $15 million to support the deployment of these early satellites. It’s a proud moment for the entire consortium, and another tangible step forward in putting practical AI to work for climate resilience.
Under Governor Newsom’s leadership, California has deployed AI-powered wildfire detection systems, expanded the ALERTCalifornia network of more than 1,000 high-definition cameras, invested in drones, satellite monitoring, real-time fire modeling, and advanced mapping technologies that help firefighters detect fires earlier, predict their spread, and deploy resources more effectively. These technology investments complement a historic commitment to wildfire preparedness: California has nearly doubled its fire protection budget from $2 billion to $3.8 billion and invested more than $2.5 billion in wildfire resilience and forest health projects. Together, these investments are helping California fight fires faster, smarter, and more effectively while building long-term resilience against increasingly severe wildfire seasons.
Here’s a closer look at the tools driving that progress: Eyes on the fire: UC San Diego and the State of California partnered to develop ALERTCalifornia, a statewide network of over 1,000 cameras to detect and monitor wildfires. ALERTCalifornia AI cameras have detected over 900 fires on state lands before 911 calls were made, and were named one of TIME’s Best Inventions of 2023. Real-time intel: The first-in-the-nation Fire Integrated Real-Time Intelligence System (FIRIS) provides real-time aerial intelligence, advanced fire mapping, and predictive analytics to support wildfire response for every incident.
Earth Fire Alliance (EFA) has named the mission the "Black Kite Trio (BK-3) Mission," inspired by a species of bird that has evolved alongside fire, representing adaptation and reflecting EFA’s vision of helping people, ecosystems, and communities confidently coexist with fire. The mission patch features the Black Kite Trio design.
In addition to the previously announced funding, Earth Fire Alliance received a $26 million grant from the Bezos Earth Fund in June 2026 to support the FireSat program and wildfire data adoption. The total philanthropic support from the Bezos Earth Fund, Google.org, and the Gordon and Betty Moore Foundation now stands at $69 million, with Google.org contributing over $15 million.
Earth Fire Alliance has also welcomed the Texas A&M Forest Service into its Early Adopter Program, expanding the network of agencies that will test and use FireSat data. The Oregon Department of the State Fire Marshal joined the Early Adopter Program in September 2025.
The FireSat launch represents a new era in wildfire intelligence, combining cutting-edge satellite technology with California’s existing detection network. As the constellation expands, it will provide firefighters, researchers, and communities with unprecedented data to detect fires earlier, predict their spread, and protect lives and property. The first data is expected within months, with global coverage by 2030.
