NASA selects GIMLI to investigate a possible lava tube beneath Marius Hills pit

Posts say NASA selected GIMLI to investigate whether the Moon’s Marius Hills pit connects to a larger lava tube. One post describes plans to use radar, seismic measurements and a gravimeter to probe underground, while cameras document the pit’s exposed walls. If a substantial cave is there, it could offer future crews protection from radiation and micrometeorites and smaller temperature swings.
