“Well, this is a thing unheard of. An Elf would go underground, where a Dwarf dare not. Oh, I’d never hear the end of it.” –Gimli, Lord of the Rings
When you think about the different elements present here on Earth, I hope you think about the different ways they bind together, combine, and add value to all we do. Extracting them is a great difficulty, as Uncle Tupelo will sing to you in their song,

For each pure element, there’s an abundance in our Solar System that’s relatively consistent across where we look, with only the gravitational gradient in our Solar System’s formation responsible for the differences.
However, our Earth is huge and differentiated, and even our richest mines pale in comparison to another location: just beneath the surface of asteroids.

Could asteroid mining pave the way to riches from space in our future? Enjoy thinking about this for our weekend diversion!
