Researchers in the United States are using autonomous drones to photograph and then analyze little-known meteorite impact sites, looking for small, well-hidden pieces of space rock

While locating craters left on the Earth's surface by large meteorites is relatively simple, it's often more difficult to find smaller impact sites, even if, scientifically, these can be just as interesting to study. American researchers therefore decided to develop an original system to search for them, using autonomous drones.
