“Space is more accessible than ever thanks to the proliferation of small satellites and more affordable launch prices, which opened the door to bespoke applications like global pollution monitoring, crop observations, and new ways of collecting weather and climate data.

Now you can add wildfire detection to the list. Satellites have observed wildfires from space for decades, but a new initiative partially funded by Google’s philanthropic arm aims to deploy more than 50 small satellites in low-Earth orbit to pinpoint flare-ups as small as a classroom anywhere in the world.

The FireSat constellation, managed by a nonprofit called Earth Fire Alliance (EFA), will be the first satellite fleet dedicated to detecting and tracking wildfires. Google announced a fresh investment of $13 million in the FireSat constellation Monday, building on the tech giant’s previous contributions to support the development of custom infrared sensors for the FireSat satellites.”
