There's certainly no sciernce that demonstrates that human life is viable on the surface of mars. Outsidfe of atmosperic gases, there is the issue of no vanallen belt, and thus no protection from the solar wind. Cellular damage has been demonstrated in every astronaut that has ever stayed on teh space station. Mars willbe the same. The surface is unihabitable. I've been saying for years: anyone who wants to know what it will be like to live on Mars should bury a cargo container in their back yard, and live in it for a year. Teraforming Nevada would be much more successful. But apparently even that's not on the table, as Earth destroying human behaviour has only accelerated since the Kyoto accords.

>Cellular damage has been demonstrated in every astronaut that has ever stayed on teh space station. Yep, I really feel sorry for the poor suckers who flew up to the ISS on that p-o-s Boeing Starliner. They thought they'd only be up there for 8 days, not enough for significant physical problems to develop. Instead, it's now been 2 months, and they're now saying they might be stuck there until February!

> no sciernce that demonstrates that human life is viable on the surface of mars Nobody claimed as much. You said "if life were viable [on Mars] it would already be there." To the degree we have science around this question, it seems to support the notion that transplanted Earth life could survive on Mars [1][2]. > Cellular damage has been demonstrated in every astronaut that has ever stayed on teh space station. Mars willbe the same. The surface is unihabitable. Cellular damage has been detected in every person who has ever been tested because that's how multicellular life works. You're not wrong about space being harsh. But you're again getting ahead of the science. We don't have real data on how human bodies work in partial gravity and partially-shielded extraterrestrial radiation environments. Anyone saying conclusively that Mars (or LEO or the Moon) is long-term habitable or uninhabitable is not speaking to the science.
