Claim summary · not a verbatim quotation
NASA studies indicate that a minimum of 160 to 500 individuals of breeding age are required to colonize an isolated landmass to ensure viability.
The finding
What the evidence shows
A minimum population estimate around 160 people for a multigenerational space voyage is real, but it comes from anthropologist John Moore's independent research, not a NASA study. Other researchers who ran the same kind of math, like Cameron Smith, landed on estimates in the tens of thousands, so there's no single NASA backed figure of 160 to 500.
