from there, a runaway greenhouse effect builds an atmosphere and oceans. we start washing out perchlorate, seed the biome with plant life, and start building colonies.

This is a way more optimistic assessment of the ease of terraforming Mars than any of the literature I've read suggests. Curious to see your sources on this.

Thank you, I'll check out both. Curious if the lack of magnetic shielding is addressed - energy requirements for an artificial one are vast, and it seems the biggest impediment to maintaining an atmosphere and protection from radiation.

this was something that worried me too, so i interviewed mckay about it directly. turns out an atmosphere on Mars would last like 100 million years. interview here:https://itunes.apple.com/us/podcast/new-world-5-lets-build-an-ocean/id1123461944?i=1000413536765&mt=2 …

so to be clear: 1) you're right, atmosphere isn't protected from solar wind, and it will slowly erode, but only on a scale of millions of years (which of course doesn't account for human technological progress in that time) 2) an atmosphere will protect humans from radiation

Even assuming no tech progress, amortization of the cost of replenishment over millions of years should drive even substantial cost towards negligible territory.

About to hit the gym and was looking for something to listen to - great timing, I'll check it out and report back. :)

Whoops, just binged several episodes (5-7, and the Hyneman episode). Now I'm chill with no magnetosphere, but very angry at nitrogen.

nitrogen is the worst!
