AI helps find missed meteorites

Antarctica is famously good at preserving meteorites, burying the rocks in snow and ice until they resurface. They often become concentrated in regions of compacted “blue” ice that make up about 1% of the Antarctic surface. But finding the meteorites within those tracts has been an ad hoc affair. Now, researchers have a new tool for the hunt: an artificial intelligence algorithm that predicts their location. A team of Belgian researchers announced last week that it employed the machine-learning software to help discover five meteorites, including a massive, 7-kilogram specimen, in . . .
