The U.S. wildfire season got off to a roaring start this year. By the end of June, more than 3 million acres had burned across the country, which is 157% of the previous 10-year average. Fortunately, wildfire responders are about to have a wealth of new data at their disposal. California-based Muon Space has launched the first three operational satellites for Earth Fire Alliance’s (EFA) FireSat constellation. EFA bills FireSat as the first constellation designed specifically for wildfire detection, monitoring, and response. The three satellites launched from Vandenberg Space Force Base aboard SpaceX’s Transporter-17 mission on Tuesday. About two hours after deployment, Muon Space confirmed the satellites were healthy and had established contact with ground operators. This launch was made possible by the success of the Protoflight mission, which sent a demonstration FireSat to orbit in March 2025. In October, the satellite identified a small roadside fire in Oregon that went undetected by existing space-based monitoring systems, validating its performance. The newly launched operational satellites will lay the foundation for the 50-FireSat constellation EFA and Muon Space hope to deploy by 2030.
