Will Martian colonists need to be bioengineered?

Until we get our shit together on this planet, it totally is. At the rate we’re going right now, we’re more likely to ‘self destruct’ first.

And of course, no matter how badly we fuck up the earth, it will always have a super nice magnetosphere, and be on the edge of the perfect zone around the sun for habitability.

Aside from the very possible existence of naive optimism about oncology from people who have never tried it and wonder why a problem that could totally just be solved by using machine learning (and possibly blockchain) to ensure the integrity of cellular source code; and why does your field need a journal anyway?; I suspect that the problem with basic Cold War solutions to radiation risks aren’t that they are too complex(a trifle tedious; but if your construction robots can’t bodge together a bunker that works in slightly under .4G your colonization attempt is going to need better robots or more shovels(for construction if you get really lucky, otherwise for mortuary purposes); but precisely that they are too banal:

If “OMG Mars colony!” actually boils down to living in a down-market Cheyenne Mountain and hoping that the life support systems are reliable enough that you get to live long enough to enjoy massive bone embrittlement; that would be a real downer(and unpleasant reminder of the “Y’know, basically anywhere on Earth would be a nicer place to live if you want to test some extreme environment gear” thing that buzzkills were always going on about).

I don’t think that even the optimists expect terraforming to shirtsleeves conditions within a generation, and cute green alien chicks(who will mysteriously find the annihilation of their ecosystem to not be a problem worth getting worked up about); but some definitely are hoping that team biotech can deliver them from colonization scenarios so unpleasant as to not be worth the trouble.
