Just wondering if we could nudge millions of asteroids from the asteroid belt; to smash into Mars and thus add to its total mass, would we not achieve a thicker atmosphere? blink.gif

No. There is not enough mass out there. Besides the corre might not be radioactive enough. Moving Mars closer to the sun via super cat would screw up the orbit of the Earth by its gravity.

Even if you could add to the mass of Mars, you would still have to supply gases to give it more atmosphere. If you could take the water ice from Ceres (it has more fresh water than Earth does) and drop it on Mars, then separate out the oxygen, that would help some. Future colonies on Mars will probably be underground.

Probably Ceres itself will be a future colony for spacemen.

Over a few centuries we could terraform Venus to give it a breathable atmosphere but it is still too near the Sun so would be too hot for us.

Atmosphere is secondary to a moagnetic core.
