THE AI ANGLE
Automating the mapping of lunar impact craters, volcanic features, and polar ice stability

NASA and IBM have released an open-source lunar foundation model pre-trained on 17 years of orbital data, including roughly two million image tiles primarily from the Lunar Reconnaissance Orbiter. By requiring only small amounts of labeled data for fine-tuning, the model accelerates planetary science tasks such as counting impact craters, identifying young volcanic structures, and estimating polar ice stability. This release demonstrates how generalizable foundation models can unlock petabytes of raw planetary remote-sensing data for reproducible research and exploration planning.

THE TEACHING ANGLE
Students can examine how pre-training a foundation model on vast unlabeled multispectral imagery enables efficient fine-tuning across diverse geological tasks compared to training specialized, task-specific algorithms from scratch.
