BRACE FOR IMPACT Artificial intelligence paints a portrait of the moon that’s even more pockmarked than previously thought.

Artificial intelligence is helping draw a more detailed map of the moon.

An AI that studied lunar images to learn what craters look like has discovered thousands of new pockmarks on the moon’s surface. This program could also be used to catalog impact scars on other moons or planets, which might improve scientists’ understanding of how various objects roamed our solar system in the past.

The new algorithm is an artificial neural network that attempts to mimic the way the brain processes information. After training on Lunar Reconnaissance Orbiter images covering about one-third of the moon’s surface, the program was shown another third of the lunar landscape. The AI identified 92 percent of known craters in that region and found about 6,000 new ones.

Previous computer algorithms designed to count craters faster and more accurately than humans weren’t as good at spotting craters in regions
