Human boots are preparing to return to the lunar south pole under active Artemis architecture, where understanding interior seismic hazards directly dictates astronaut survival and habitat engineering. By applying advanced digital signal processing to analog magnetic tapes recorded during four later Apollo missions, researchers extracted deep seismic signals once thought lost to background static. Paired with independent 2023 laser ranging measurements led by French teams and recent material analyses from Chinese lunar samples, the evidence confirms the Moon possesses a solid metallic inner core enveloped by a fluid outer layer and a partially molten mantle boundary. These findings rewrite older assumptions about how our nearest neighbor cooled over billions of years. Yet planetary geophysicists still cannot fully explain the exact compositional gradient within that deep boundary zone or how long a lunar dynamo could have generated an ancient global magnetic field.
