Accumulation on the Lunar Surface

The Moon's surface, or lunar regolith, has been bombarded by solar wind, embedding helium-3 within its soil. Periodic impacts by meteorites mix the regolith, bringing helium-3 closer to the surface over time. Estimates suggest that millions of tons of helium-3 are spread across the Moon's surface, presenting a tantalizing opportunity for energy developers, as noted by Interesting Engineering.

DID YOU KNOW: The Moon's regolith contains an estimated 1.1 million metric tons of helium-3, enough to power the Earth for thousands of years.
