Space seems like a long way to go versus just mining within the existing gravity well. What elements (other than hydrogen) do we lack?

- sokoloff 5y agoDid you mean to say helium? The Earth is 75% covered with hydrogen-rich raw material, so I’d expect it to be plentiful, with the mines for it needing energy, but otherwise be straightforward.
- Chris2048 5y agoFair enough. By mass hydrogen is rare, but by accessibility easily obtained. But prising it away from Oxygen would probably make it uneconomical, not that space mining is much better.
