In theory, but the biggest problem is creating a big enough atmosphere. It would require many billions of tonnes of gas. More than could ever be produced. |
Assuming the production problems could be solved wouldn't the absence of a protective magnetic field allow cosmic winds to just erode away any atmosphere one might create? |
Yep, that would happen. But you all must know this: Mars has an atmosphere (
Link). All you need to do, and I know I'm making this sound easy, is to alter the atmospheric compostion to an "Earth Composition." You would also need to find a way to raise the atmospheric pressure to a liveable level.
Mars' Atmospheric Composition:
95.72% Carbon dioxide
2.7% Nitrogen
1.6% Argon
0.2% Oxygen
0.07% Carbon Monoxide
0.03% Water vapor
0.01% Nitric Oxide
