What lurks within the Moon’s underground lava tubes? Entrances or “skylights” to lava tubes might allow future explorers access to subsurface ice.

The drum beat of back to the Moon with humans “this time to stay,” is fueled by harvesting available lunar resources. Many see plunging into the floors of permanently shadowed polar craters. Water ice found resident in these everlastingly shaded “cold traps” is thought to be stable and exploitable.

But there may be other spots on the Moon that could yield a scientific motherlode of data – as well as survive and thrive resources to sustain human occupation of Earth’s celestial next door neighbor.
