History
Mackinac Island was the third of three iron meteorites encountered by the rover on Meridiani Planum within a few hundred meters, the others being Shelter Island and Block Island.[2]
Mackinac Island may have fallen on Mars in the late Noachian period and is extensively weathered.[2][5]
gollark: And/or somehow more direct citizen involvement, although that could EASILY go horribly wrong.
gollark: The issues I think are most problematic are just companies being able to influence governance, and I'm not really sure what to do about that. Perhaps just have strong norms about having the government not do much.
gollark: You'd need a way to somehow be able to have some of the profit from new fundamental stuff go back to its original investors.
gollark: Probably some kind of long-term research investment things?
gollark: I think with better coordinating/financial structures in place we could probably have better encouragement to do fundamental stuff.
