The project aims to detect a fire the size of a classroom within 20 minutes. Wildfires are becoming an increasingly common threat worldwide. Record-breaking burns from Australia to the Amazon to the United States are devastating the environment. The deadly wildfires that raged across Los Angeles in January were estimated to have caused more than 250 billion in damages. Current satellite imagery is often low resolution, infrequently updated and unable to detect small fires.

Amid an outbreak of recent wildfires in California, Google announced a commitment to spend 13 million to improve satellite imaging to help track and detect wildfires, starting as early as next year. FireSat, a constellation of more than 50 satellites, will be able to detect wildfires as small as the size of a classroom, about 16 by 16 feet, and the first satellite will launch in early 2025, the media giant announced Monday. Firefighting authorities currently rely on satellite imagery that detects wildfires but only when they reach about the size of a football field, or more than an acre. "We realized that if we can pair satellites with machine learning and artificial intelligence, it was the perfect platform to generate real-time operational intelligence on fires," Christopher Van Arsdale, who leads the Google Research Climate & Energy group and is chairman of the Earth Fire Alliance, said in a video announcement. The initiative is being led by the Earth Fire Alliance, a nonprofit that was launched in May to create FireSat and develop wildfire datasets, with funding from Google and the Gordon and Betty Moore Foundation.

As the threat of wildfire worsens in California and across the world, a growing number of federal agencies, nonprofit organizations and tech companies are racing to deploy new technology that will help combat flames from a whole new vantage point: outer space. New satellite missions backed by NASA, Google, SpaceX, the California Department of Forestry and Fire Protection and other groups were announced this week and promise to advance early wildfire detection and help reduce fire damage by monitoring Earth from above. Collectively, the roster of big names, billionaires, government groups and nongovernmental organizations reflects a considerable interest in using new technology to solve some of humanity's biggest problems. Fire weather days have increased in Western U.S. over the last 50 years, with some of the largest jumps in California, according to a new report by Climate Central, a nonprofit news outlet that reports on climate change. Among them is the Earth Fire Alliance, a global nonprofit coalition that recently unveiled its vision for a constellation of more than 50 satellites that will focus specifically on wildfires and their ecological effects.
