Episode notes
Space Resources Trump Earthly Costs
- Space offers resource abundance without Earth's environmental and social extraction costs.
- Asteroids and lunar regolith contain metals and volatiles untouched for billions of years.
Moon For Bulk, Asteroids For Rich Veins
- The Moon is best for bulk materials and proximity while asteroids concentrate precious metals.
- Asteroids often retain mixed metals, making them richer targets for PGMs than lunar regolith.
1‑km Asteroid Could Outmine Earth
- A 1 km nickel-iron asteroid could hold roughly 250,000 tons of gold, exceeding all gold ever mined on Earth.
- Lunar regolith contains gold at parts-per-billion levels, far too diffuse to match such asteroids.
