For generations, humanity has gazed at the Moon and sent instruments to listen — accumulating a vast but largely inaccessible archive of lunar knowledge. Now, IBM and NASA have released an open-source AI foundation model trained on decades of multi-mission lunar data, offering scientists a shared language for translating raw observation into actionable understanding. The model improves detection of lunar ice deposits, craters, and volcanic features with measurable precision gains, and its open release invites researchers worldwide to build upon a common scientific infrastructure. It is a quiet
