Why go to the Oort cloud when the Kuiper belt is so much closer?Pressure domes would probably be the best way to start out. Assuming unlimited resources, it might not be a bad idea to go out to the Oort cloud and get some comets, bring them back and crash them into the surface. Give Mars more mass and more water. And yes, it would take a lot of comets to do this.
And I can spend all the money I save on hookers and blow!
Well, you do it your way, I'll do it mine.
According to Wikipedia, the mass of the Earth is 5.9736 x 10^24 kg. Some discovered asteroids in the Trojans weigh:You've got all the mass you need in the Kuiper belt. We're talking many Earth masses worth of the stuff.
Even better though would be the Trojans, just a small hop away from Mars and good ice content. Not sure about total mass though.
I dunno, the total mass of Earth's hydrosphere is 1.4 × 10^21 kg. Those other ones are probably significantly smaller. It's certainly a start but I wouldn't say that it's the be all and end all.According to Wikipedia, the mass of the Earth is 5.9736 x 10^24 kg. Some discovered asteroids in the Trojans weigh:
Greek camp:
588 Achilles - 2.6×10^18 kg
624 Hektor - 1.4×10^19 kg
3596 Meriones - (No estimated mass, but it's diameter is 175 km)
Trojan camp:
617 Patroclus - 1.36×10^18kg
And those are just the ones Wiki had articles on - there is a long, long list of asteroids in both "camps". It seems apparent that there is more than we would need for any terraforming project, assuming it's of useful materials.
Mars is a crap place to live.
-it's too cold, not enough sunlight
-the gravity is t0o low (the effects on human growth are unpredictable)
-no protection from solar radiation/wind
-planet is too small to retain an atmosphere
any settlement there would consequently be high unviolable. In fact there's no good reason for people to go there at all. Rather we should concentrate our science and resources on improving the situation on Earth IMHO.

Settlements on Mars would have to be totally enclosed of course..I wonder if people could deal with not beiong to go outside? Ther ewould have to be massive indoor parks to compensate.
