Three satellites in the Google-backed FireSat constellation launched on July 7, 2026, marking a step toward faster wildfire detection from space Source: arstechnica. As smoke from hundreds of fires blankets North America, this launch represents the first purpose-built satellite constellation for wildfire detection, capable of spotting fires as small as 5x5 meters. Meanwhile, other efforts are underway globally.
Greece has deployed four thermal-imaging satellites, built by OroraTech, to predict and monitor fires, with access to about 20 more OroraTech satellites Source: aljazeera. The Hellenic Space Center uses these to see through smoke and plan overnight firefighting. OroraTech itself, a Munich startup, operates numerous thermal infrared satellites to fill the 'afternoon gap' when conventional NASA and ESA satellites are not imaging Source: dwnews.
FireSat will initially cover the United States, Australia, and Europe, with hourly global coverage targeted by 2029 and 20-minute revisit times by the early 2030s Source: arstechnica. Greece plans to launch seven additional multispectral satellites this year Source: aljazeera. These systems aim to complement existing free data from NASA's FIRMS and the European EFFIS, but with higher resolution and faster revisit rates Source: dwnews.
“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 managed by the nonprofit Earth Fire Alliance.”
“'The systems of NASA and the European Space Agency (ESA) usually only take images at a specific time of day,' explains Thomas Grübler, chief strategy office at OroraTech. For example, only in the morning or at noon.”
“These satellites are Greece’s first with thermal imaging technology and are set to revolutionise fire response in the country at a time when climate change is causing drought and frequent wildfires.”
“FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss.”
“'The satellites can tell us where the fire fronts are at night, which is extremely useful for the fire service when it’s planning the first morning water-bombing flights,' Tryfon Farmakakis, a space systems scientist at the HSC, told Al Jazeera.”
