Yeah, that's all cool and accurate, but Mars has a third of the Earths' gravity, people are not gonna be livin on Mars unless folks want everyone who grows up there to suffer bone disorders and osteoporosis

IF there's a future for humanity in space, it's gonna be in space habitats

The tech-capitalists obsession with Mars is stupid not because of the science but because of the economic, medical and social implications that they don't care about or understand
