Why Lunar Helium-3 Mining Still Can't Compete With Earth

When it comes to Helium-3, the biggest cost divide is between Earth and the Moon. Potential sources range from tritium decay and terrestrial helium wells on Earth to lunar regolith on the Moon. Today, Earth-based sources remain far easier and cheaper to access. This graphic, created by Visual Capitalist's Cody Good in partnership with Pulsar Helium, compares major potential sources of Helium-3 by cost, scalability, and accessibility.
