Enough water on Mars to cover the entire planet!!

It would be interesting to live with .3Gs....

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

And how would you do this? With Water of course! SOme good old Earth pollutants can also help out a bit! ie. The greenhouse gas type.

What most people don't know if that Mars was very similar to Earth at one point in time. Life is also a possibility. Europa also may harbor life. I suspect Mars will be studied even more closely now.

I read somewhere about the moons potential as a retirement community. 1/6th gravity means 1/6th the physical effort to move around and 1/6th the load on the heart.

Not somewhere one could expect to get a lot of visitors though...

So atmospheric erosion would effect pressure rather than composition?

No, solar winds do not effect pressure directly.
Mars has a atmosphere much thinner than Earths, so there is less pressure. The atmosphere above us on Earth exerts a surprising 10.2 tonnes per meter squared at sea level. On mars the atmosphere gives less than 0.1 tonne per meter squared, as a result we (humans and animals) would "inflate" under the relative vacuum.

Solar winds do, however sweep the outer layers of atmosphere out into space. This isn't a issue for earth as our molten core provides a magnetic field which deflects the solar winds, but mars has a smaller, solid core (or semi-liquid) which only provides a weak magnetic field. As a result it has lost at least 1/3 of it's atmosphere; therefore reducing atmospheric pressure indirectly.

To create a sustainable atmosphere we would first need a strong magnetic field for mars, this isn't a huge problem if you can create enough power, however it would need far more power than every power plant together have ever created so far.

We go from planet to planet, conquering and destroying everything in a trail of annihilation we leave behind.

Earth got pwnd, now its time to find a new victim.

To be honest it would be hard to actually make mars worse than it is already.....

Good point. Hostile doesn't even begin to cover it. Could be worse though - The moon.

Actually, wouldn't it affect both?

Because there is no magnetic field, would the solar winds just erode the upper layers of the atmosphere, decreasing the amount of atmosphere on the planet. Hence, less atmosphere would mean less pressure, right?

Also, what is Mars' core made from?

Yes, thats what I said! t just does not effect pressure directly - it does it throught the errosion of atmostphere.

We can not know with any degree of certainty without conducting seismic tests on mars. However it is thought that mars will have the same materials in it's core as earth, but in different amounts. Like Earth it will have a nickel/iron core. Either a large solid one or a small semi-liquid core. It is likely that mars contains less radioactive materials than Earth (uranium, radon, carbon etc). I don't know any more than that.

Maybe we should go to the moon first since we could glean every last resource on the thing - the Space Hoover is active and functional. Don't beleive me?
