Re: Aerogel martian habitats.
Mars' surface temperature occasionally exceeds 273K locally even under current conditions. If I recall correctly, it would reach an average of 273K well before 1 bar (500-600 mb?).

Re: Aerogel martian habitats.
More bioengineered bacteria for that, I think.

Re: Aerogel martian habitats.
I like it! A steam heated Mars.

Re: Aerogel martian habitats.
I've read that platinum catalysts could be used somehow. But I'd go with biotech too.

Re: Aerogel martian habitats.
Catalysts make a reaction that would happen anyway faster (sometimes much faster), but mostly the way you neutralize acids is by combining them with a like amount of base.

It's too early to get too excited about either an optimistic or pessimistic appraisal of terraforming prospects, or terraforming technologies. Maybe we'll discover there's more CO2 on Mars than we know about in some form or another, maybe we'll discover that Mars' gravity and mass are just too low to make it work CO2 or not. Maybe, by the time we're ready to try terraforming it, we'll have tech that looks like magic to us now. Maybe we won't. Still, I've thought for a long time that SF tends to understate the difficulty and complexity of terraforming. A rule of thumb I use to remind myself of the scale of terraforming operations: imagine if someone put out a tender for a project to move the Atlantic Ocean somewhere else. That helps put this stuff in perspective.

Re: Aerogel martian habitats.
Well, realistic timescales wind up not being very interesting. I mean, it took about two billion years for Earth to go from the initial evolution of blue-green algae to having a breathable atmosphere.

Re: Aerogel martian habitats.
That was the time needed for the oceans to rust. I kid you not. Billions of tons of dissolved Iron bound all the oxygen for a billion or so years.

Re: Aerogel martian habitats.
That was part of it, but a lot of it was just being slow.
