NASA Chooses GIMLI Mission to Probe Marius Hill Pit for Lunar Cave

NASA has selected the GIMLI project to investigate whether the Marius Hill Pit on the Moon opens into a vast underground cave or lava tube. The mission will deploy radar, seismic sensors, gravity measurements, and cameras to map the subsurface and estimate the size of any hidden void. Findings could reveal new details about the Moon’s volcanic past and identify potential natural shelters that might protect future astronauts. By exploring this mysterious pit, scientists aim to deepen understanding of lunar geology and assess the feasibility of using lunar caves for human habitation.
