or does a planet need active volcanoes, molten core, a moon perhaps for tides (etc) in order to make it "work"?
As far as I know the only reason the earth's moon was vital for life is because it slowed down rotation.
Mars may have a molten core, I wasn't sure...
I believe the heart of Mars is a cold one.

So we would have to keep pumping the gas in forever then? They never mention that part...

When I said eventually I was pretty lax on the details. It took Mars a couple billion years to get the way it is now.

Hi Jinxed, Josh,
I watched a good show on terraforming Mars a few months ago. It seems there's at least a few scientists who think this is possible relatively quickly because of all the CO2 locked in the ice caps. Here's a web site that covers alot of the stuff I saw.http://www.geocities.com/marsterraforming/terraforming.html
It's pretty interesting but I'm still a little unsure of how well it would maintain itself. I thought a magnetic field was critical, but I can't reference that just now.

But how did the carbon dioxide get in the icecaps in the first place? One can only assume that Marse was so cold with the COČ in the atmosphere that the gas froze. Wouldn't you agree?

That would be a catch-22, eh. This subject isn't my strong suit, but it's real interesting. I'm reading through this website now. http://www.windows.ucar.edu/tour/link=/mar...te_history.html
I like the way it's put together with alot of tangent links. I'll keep digging and trade insights with you.

That's a damn good question!
What would freeze the very thing that would make it un-freeze?
I wonder if there are any computer simulations that could figure out what Mars' average temperature would be given an Earth-like (or close to it) atmosphere. It might be just too far away from the Sun to maintain an above-freezing climate regardless of the atmosphere...
Or... I might be really wrong.
