A new firefighter launches into space

Published:

The world’s first FireSat satellite blasted off Saturday from Vandenberg Space Force Base in California, ushering in a new era of faster wildfire detection and response. Using advanced thermal imaging, FireSat can spot fires early — even in remote areas — and help firefighters prevent small blazes from becoming catastrophic disasters.

Developed in collaboration with firefighters, disaster response specialists, scientists and others — and built by satellite maker Muon Space — this innovative technology gives firefighters the critical data they need to respond faster and more strategically to blazes. By overcoming challenges like poor visibility and unpredictable fire spread, FireSat can help save lives, protect communities and reduce wildfire devastation in an era of rising global temperatures. 

The satellite is equipped with cutting-edge instruments that can detect fires as small as 5x5 meters, about the size of a classroom. Once the first phase of the system is operational, in 2026, FireSat will scan the entire planet at least twice a day, with even more frequent passes over wildfire-prone areas such as the western United States. By 2030, a constellation of more than 50 FireSat satellites will enable fire monitoring anywhere on the planet every 20 minutes — and as often as every nine minutes in high-risk zones.  

These near real-time observations will allow officials to spot fires quickly and deploy crews to outbreaks early, potentially stopping small fires before they become uncontrollable. During active fires, satellite imagery can help firefighters track and predict spread, so they can focus efforts where they will be most effective.

FireSat’s data is also expected to drive new wildfire prevention and response strategies by increasing scientists’ understanding of fire dynamics — protecting lives, homes and forests while preventing the release of harmful air pollution and millions of tons of climate-warming carbon dioxide from burning forests. Reducing greenhouse gases can help to break the cycle in which rising temperatures and dry conditions fuel more intense wildfires, which in turn release even more emissions. 

Satellite observations will also aid forest managers in conducting prescribed burns — controlled fires that reduce fuel buildup and promote healthier, more resilient forests.  

"FireSat can be a game-changer for managing wildfires, which are an increasing threat to communities and ecosystems around the world," says Steven Hamburg, chief scientist at Environmental Defense Fund. “We will use the data FireSAT provides to better define wildfire climate impacts and maximize the scientific and management benefits of the information we will have access to.”

EDF conceived of the satellite-based fire detecting system and led its early development beginning in 2021. Hamburg and his team are now developing a support structure to ensure that the FireSat data is accurately and effectively used. 

Saturday's launch is a critical step toward better wildfire management. As greenhouse gas emissions continue to warm the atmosphere, drying out forests and creating longer fire seasons, scientists warn that wildfires will become more frequent and intense, making advanced detection systems more urgent than ever.  

The expected benefits are substantial: According to Earth Fire Alliance, the nonprofit coalition that operates FireSat, measures enabled by FireSat could annually save $1-2 billion in U.S. fire suppression costs, protect 9,000 to 18,000 homes and businesses, reduce burned areas by up to 4.5 million acres and cut carbon emissions by 60 to 113 million tons.   

FireSat’s launch marks the beginning of a new approach to wildfire management — one driven by data, speed and precision. As wildfires grow more frequent and severe in a warming world, FireSat offers a powerful new tool to protect lives, communities and ecosystems while reshaping how we respond to one of the most pressing challenges of climate change. 

Hope for a warming planet
