ATHENS, Greece (AP) — In the searing Mediterranean summer, wildfires turn dangerous in minutes.Greece has learned that at a terrible cost. In 2018, a blaze east of Athens moved with ferocious speed, killing more than 100 people. Five years later, a massive fire tore through a remote nature reserve; it was the largest wildfire ever recorded in the European Union.Greece is looking to the heavens for help, with a dedicated satellite constellation that monitors for fires. It’s a model for the continent as Europe races toward broader independence in space technology.AdvertisementAdvertisementFour satellites, each smaller than a piece of carry-on luggage, were launched into low orbit in May. That made Greece the first nation in the world to integrate a dedicated satellite array into its national firefighting system.Built by German company OroraTech, the satellites carry thermal sensors designed to flag new blazes as small as four meters (13 feet) wide, beating traditional satellites that can only spot fires the size of a cruise ship.Satellites help manage multiple wildfiresAs Europe struggles with its latest blistering heatwave, the high temperatures foreshadow the wildfire season. Fires pose a unique challenge in Greece with its tinder-dry mountainous mainland and over 100 inhabited islands.If a fire ignites, AI-processed satellite data is sent as an alert to commanders with the location, size and intensity already calculated. If multiple fires are burning at once, real-time data is crucial to determining response.AdvertisementAdvertisement“For example, if you have 10 fires all over Greece and the fire radiative power is lower in some cases, you will not give priority to those ignitions; you will give priority to other ones,” Fire Service Col. Zisoula Ntasiou, vice president of the International Association of Fire and Rescue Services, told The Associated Press in an interview.Thermal sensors also pick up solar panels, hot factory roofs and sunbaked rock faces, but AI models are built to filter out those false alarms before alerts reach emergency services, according to officials involved in the program.Hotter summers require better AI modelsGreece recorded its hottest summer on record in 2024 and its third-hottest last year.“The global temperature is going up. That causes fires to change in intensity and ferocity,” Ioannis Lantouris, head of OroraTech’s Greek operations, told the AP. “Our models have to change and adjust to that. They have to be faster. They have to be more precise.”AdvertisementAdvertisementLantouris spoke in his office in Athens, while engineers worked on fire behavior models. Near their desks, they keep a life-sized replica of the satellite.Thermal satellites add a layer of detection to drones and ground sensors, and Greece has expanded both since the 2018 disaster forced an overhaul of wildfire response. The constellation helps fill coverage gaps from internat …
