In the same interview, the billionaire suggested Mars’ inhabitants might live under a glass dome with an “outdoorsy, fun atmosphere,” until the planet is terraformed — artificially transforming the planet to make it more Earth-like, with a livable atmosphere.
But that plan also presents a problem: A 2018 NASA-sponsored study concluded terraforming Mars is impossible, because there is not enough carbon dioxide locked in the soil to release into the air.
Musk, however, isn’t daunted. He has suggested exploding 10,000 nuclear missiles over Mars’ surface in order to melt the planet’s ice reserves, thereby releasing the carbon dioxide locked within. His company has even produced “nuke Mars” T-shirts.
But one major problem none of these dreamers have been able to solve is human procreation: It may be extremely difficult in space. Never mind the challenges of having sex in diminished gravity. The radiation in space could “render males temporarily and females permanently sterile,” Nadis writes.
Another more serious problem is that they eyes are actually the MOST sensitive to deadly space radiation. It has been estimated that anyone flying to Mars will be blind by the time they get there, just due to the deadly space radiation that all crews will be exposed to on the 9 month journey.
Good luck with that.. Plus the fact that even if you can have kids, all of that radiation will almost guaranteed mess up the DNA of the sperm and/or eggs that do survive somehow, so you end up with genetically deformed monsters as kids..
