Muon Space has achieved a significant milestone in its wildfire detection efforts. The company has released the first thermal infrared images captured by its FireSat Protoflight satellite. These images, obtained using a six-channel multispectral infrared instrument, clearly demonstrate the satellite's capacity to detect and measure thermal signatures from space.
Launched on March 14 aboard SpaceX’s Transporter-13 mission, the satellite has already produced impressive results. The images showcase a range of thermal phenomena, including urban heat islands and airport runway activity in Sydney, Australia; lava fountains at Hawaii’s Kīlauea volcano; and gas flares at Libya’s Sarir oil field complex. “These first light images confirm that our IR sensors are operating as designed and collecting high-quality data,” confirmed Dan McCleese, chief scientist of Muon Space.
Unlike visual cameras, the FireSat sensor's unique capability lies in its ability to detect heat. Each pixel in the image represents a ground temperature reading, enabling the detection of subtle temperature variations, from water temperature shifts to the intense heat of volcanoes – and, critically, the early indicators of wildfires.
The FireSat initiative is a collaborative effort, spearheaded by the Earth Fire Alliance (EFA) in partnership with Muon Space. It receives substantial financial backing from Google Research, the Gordon & Betty Moore Foundation, and other environmental organizations. The project’s ambitious plans include the launch of three additional satellites in 2026, with a target of over 50 satellites forming a constellation by 2030. This constellation aims to provide at least twice-daily global coverage, with enhanced frequency for wildfire-prone areas, eventually achieving 20-minute revisit times worldwide.
This innovative constellation addresses limitations in existing wildfire detection methods, which often depend on ground reports, aerial patrols, or general-purpose satellites with limited resolution. The FireSat constellation will serve various stakeholders, including first responders, land management agencies, and research institutions dedicated to studying fire behavior and its impact on the climate.
