Meteorites offer tantalizing clues about what the early solar system was like. But finding them is far from rocket science. Often, researchers simply fan out across a landscape and walk for hours while staring at the ground. Now, some scientists are turning to drones and machine learning to help spot freshly fallen meteorites much more efficiently.
A team of six people on a meteorite-hunting expedition can search about 200,000 square meters per day, says Seamus Anderson, a planetary scientist at Curtin University in Perth, Australia. But since the area over which a cluster of meteorites falls typically can’t be pinpointed to better than a few million square meters, searching
