As smoke from hundreds of burning wildfires spreads across Canada and the United States, three operational satellites in the Google-backed FireSat program have successfully launched into orbit. The launch marks a significant step towards providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year.
The FireSat constellation, managed by the nonprofit Earth Fire Alliance, represents the first satellite constellation purpose-built for detecting wildfires. Each satellite is equipped with multispectral imaging that can peer through smoke and clouds and detect fires as small as five by five meters—about 16 by 16 feet. The capability was proven by a FireSat Protoflight satellite that launched in March 2025 and collected more than one million images, while showing it could detect low-intensity blazes invisible to existing satellites.
The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to “initial operational capability” for the FireSat constellation. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day.
FireSat has received significant financial support from Google, with over $15 million committed to support initial deployment. Other notable supporters include the Bezos Earth Fund, which has pledged $26 million. The nonprofit Earth Fire Alliance aims to provide the latest imagery anywhere in the world on an hourly basis by 2029, and eventually every 20 minutes once the full constellation of more than 50 satellites is launched by the early 2030s.
The detection of small wildfires before they burn out of control could prove extremely helpful. The Earth Fire Alliance has projected that even an hourly revisit rate by the FireSat constellation could help save more than $1 billion in fire damage costs and prevent nearly 22 million tons of carbon emissions, along with protecting 3,500 homes and 1.3 million acres of land.
However, experts warn that climate change remains a major challenge in preventing blazes from spiraling out of control. The wildfires burning in Canada’s boreal forests this summer are just one example of the devastating impact of global warming on fire-prone regions. Traditional fire suppression has proven inadequate in these cases, and fire agencies need more resources to manage ecosystems through prescribed burns and put out unwanted fires.
Silicon Valley’s rush to deploy AI models has also come with considerable climate costs linked to a worsening wildfire problem. Larger AI data centers require massive amounts of electricity that are often being met by new natural gas projects in the United States, which could collectively emit more than 129 million tons of greenhouse gases per year.
Google Research plans to use its AI models to compare operational FireSat data with historical images in order to accurately identify very small fires and inform predictive modeling of wildfires. The company celebrated the launch of the first operational FireSat satellites by describing the event as “another tangible step forward in putting practical AI to work for climate resilience.”
