Four superpowers would be far more stable.

You know, mars is a dead rock, much like the moon. It can't support live. There's nothing we can do about that.

 

There are lots of stuff we can do about that, it's not viable to try terraforming at the moment though. Until then it's always possible to create pressurized greenhouses and just build any structures so that the air doesn't get out. Mars has plenty of raw materials, and supplies from earth could sustain a small population.

Mars can never become a earth-like planet. It's core is dead, and it has no stabilising moon - let alone a schield against the suns' radiation. It has huge duststorms, and very little water.

To build something on Mars, you need a reason to spend huge, and huge, amounts of money. There really isn't one, that's why we never build a base on the moon. Hugely expensive for so, so little gain.

 

We don't really know if the core is completely dead, only that a huge meteorite impact stopped it from spinning and generating a magnetic field that could keep the solar wind away, and thus the planet's water was blown away by the solar wind.

If it turns out that Mars has a liquid core, perhaps in some way altering the course of one of its moons and making it collide with the other to combine into one big moon that could have the same effect as the earth's moon on the earth's core. Or maybe some fancy large-scale magnetic field generators will be invented in the future. And then, the solar wind problem would be gone.

And, Mars would only need to be able to sustain itself for colonization to be a good idea, dead rock or not. Since humand are experts at altering the enviroment we live in, a self sustaining society on mars isn't an impossible idea, the amount of energy from the sun that reaches mars' surface is close to the amount on earth, so solar power is a viable option for energy, and ther is still frozen water on the planet.. A small self-sustaining society could grow, and maybe one day, Mars could have a big population. Starting such a colony is maybe too expensive today, but as tech becomes cheaper...

Sorry for the long response, it's just that I have given this subject a lot of thought before :P

They scanned the field and found only small pockets left. Mere remnants. And I don't remember reading about any  record of tectonic activity on mars. The core seems dead... or dying.

About creating a moon for mars, that could work. I didn't think about it like that. Lot's of work though.  

In order too generated an artificial field like you say, they would have to make cold fusion in a huge way - If it's possible and practical. What else can generate that kind of power?  That would be expensive.

I like to think about space and stuff too. But i'm more cynical about it. IMO manned space-exploration is useless. Robots are the future astronauts. Go robot.

In the long run man can't leave earth. He needs earth's ecosystem and that can't be replicated - or at least not in good enough terms. Not in a ship, and certainly not on a planet. It's a fun idea, but it doesn't work. It's sad.
