This mysterious hole on the Moon may open into a giant cave

NASA has chosen a proposal led by the Planetary Science Institute to determine whether a potentially large cave stretches underground from the opening of a pit on the Moon. If such a cavern exists, it could eventually offer astronauts natural protection from radiation and the dramatic temperature changes experienced on the lunar surface.

The project will receive funding through NASA's Payloads and Research Investigations on the Surface of the Moon (PRISM) program. PRISM sends scientific instruments to the lunar surface aboard spacecraft supplied by providers participating in the Commercial Lunar Payloads Services (CLPS) initiative.

The results suggest fasting may influence health in ways that go beyond weight loss and could eventually inspire treatments that mimic its effects.
