Today, three new FireSat satellites successfully launched from Vandenberg Space Force Base in California. This expands the FireSat program, a global initiative led by the nonprofit Earth Fire Alliance (EFA) to create an unprecedented wildfire dataset. Google Research has teamed up with leaders in the fire community, including EFA and satellite manufacturer Muon Space, to create this purpose-built constellation designed to provide the continuous coverage fire agencies need to detect wildfires before they spread.
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 5×5 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.
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.

Three newly launched FireSat satellites reached low Earth orbit on July 7, 2026, marking a major milestone in global, near-real-time wildfire detection.

The satellites are the result of a collaboration known as the Earth Fire Alliance (EFA). This global nonprofit coalition brings together spacecraft manufacturer
Muon Space, technology partner Google, and state agencies like CAL FIRE. Backed by more than $15 million in funding from Google.org alongside major philanthropic contributions, this initiative leverages custom-built infrastructure and artificial intelligence to completely change how blazes are spotted.
[1, 3, 5, 6, 7, 8] Why the New FireSat Satellites are a Game-Changer
Traditional weather satellites typically only capture an area every 12 to 24 hours and focus on massive footprints. In contrast, the purpose-built FireSat constellation relies on a highly advanced, mission-specific design: [1, 8, 9, 10]
- Unprecedented Resolution: Equipped with specialized multispectral infrared sensors, these satellites can detect early-stage brush and roadside fires as small as 5×5 meters (the size of a shipping container). [1, 11, 12]
- Extreme Penetration: The sensors are uniquely calibrated to track heat signatures through thick smoke and clouds. [3, 11, 13, 14, 15]
- Intelligent Mapping: Built-in AI elements analyze heat intensity to separate dangerous, rapid-spreading wildfires from cooler, smoldering blazes. [12, 13]
- Persistent Tracking: Unlike manned fire-spotting aircraft, the orbiters can consistently log data over remote, hard-to-reach zones without interference from heavy winds. [12, 13]
The Roadmap to Full Global Coverage
The newly deployed trio will undergo a three-month commissioning and calibration window. Critical situational data is expected to start flowing directly to emergency responders and incident commanders by late 2026. [7, 11, 16]
The three orbiters join a highly successful pilot “Protoflight” satellite launched in early 2025, which spent over a year capturing more than one million images to prove the technology’s effectiveness. The long-term plan aims to scale this system into a massive network of more than 50 satellites by the early 2030s. Once fully built out, the constellation will scan the entire planet, delivering critical wildfire updates to frontline emergency teams every 20 minutes or less. [6, 11, 17]
