I remember reading somewhere it was around 500-1000 for a sustainable human colony to begin. Did we get better at avoiding Hapsburg Jaws?
I was wondering the same thing before reading the article. This is for a 28 year mission, and doesn't include setting up the base, or power and water supply.
I think that number comes from long term genetic diversity issues. Some rule in biology about inbreeding depression came up with it
If it’s basic generic viability I’ve always heard 30-60 though I couldn’t name a source for that.
