The big picture: Greece is turning to space-based hardware to help firefighters detect wildfires earlier and see them more clearly as blazes burn across Attica and popular island resorts. A new thermal satellite network, called the Hellenic Fire System, is now feeding data to authorities while crews learn how to use it ahead of its planned full deployment in September. Its ultimate impact will depend on how smoothly the technology fits into daily firefighting operations and how reliably it can support decision-making during the next severe fire season.
The system is built around four small satellites that fly in low Earth orbit and repeatedly pass over the same areas. Developed by German firm OroraTech in partnership with the Hellenic Space Centre, the constellation is designed specifically to detect fires and hotspots rather than serve as a general Earth observation platform.
Ioannis Lantouris, OroraTech's head of operations in Greece, said the satellites can detect heat sources as small as 4 by 4 meters. "It doesn't just take pictures," Lantouris told the Financial Times. "We process the pictures on the satellite and then send them down to Earth." That processing happens onboard, with software running on the spacecraft to analyze each image, screen out likely false alarms, and package only relevant fire data for teams on the ground.
