[QUOTE=wonkadonk;22911837]why would you hope for most of earth's oceans and atmosphere to be blasted away[/QUOTE]
Not really hope, just know.

if you're gonna freak out about earth turning into a wasteland then use Venus as an example of what it most likely would be like
[QUOTE=BCell;22901437]This makes me think Mars can be turned into Earth in the future[/QUOTE]
Nein.
Unless we can find a way to return Mars' core to its molten state and start it spinning again (or through some other means) to generate a magnetosphere any terraforming attempts would be very temporary.
The solar wind would tear Mars' atmosphere from it once more leaving it as it was prior to our meddling with it: a lifeless, cold rock.

What if you have a bunch of satellites orbiting mars with strong electromagnets providing an artificial magnetosphere?

You'd probably end up blocking out the sun with them because you'd need so many of them.
You'd have better luck building a spherical 'shell' around Mars' atmosphere that would let light through, but not the charged particles ejected from the sun (which are the problem).
And even that would be a monumental task that would be completely absurd and fraught with problems. You couldn't just let it 'orbit' Mars because it wouldn't be a perfectly stable equilibrium. Eventually it would come out of place and it and Mars would collide. You'd have to hold it in place with probably HUNDREDS of space-elevator like structures or something like that.
What about those scientist working on creating a miniature sun? Could we chuck ones of those inside the core to try and heat it up again?(over-simplified:Not my field of expertise.)

Hmm, never thought of that. What about towers build around cities that provide a mini magnetic field around them?

Hmm, I think you're thinking of nuclear fusion, which the media frequently refers to having a "micro-sun". It wouldn't really be of any help to the core.
[QUOTE=wonkadonk;22913613]Hmm, never thought of that. What about towers build around cities that provide a mini magnetic field around them?[/QUOTE]
In that case it'd just be simpler to build physical domes around the cities that hold in the atmosphere and give protection from the harsh solar wind and the cold Martian environment outside. Generating a city sized magnetic shield would be incredibly inefficient and it would mess with the electronics city wide.
Not to mention, if the power source decides to conk out for your city sized magnetic shield then you're in a little bit of trouble to say the very least.

Hmm, so it seems that terraforming mars is a really impossible idea

Just double checking...
God...I wish life was like Spore sometimes...then we would just have to spam atmosphere blowers, trees and some other stuff!

Not necessarily impossible, just absurdly difficult and not within humanities reach at the moment.
But something like building smallish (maybe hundreds of metres to a few kilometres wide) domes on the surface, growing plants in them and then putting settlements in them should be entirely possible. If you dotted the entire surface with them then linked them up via some railway system or something you could probably get a fair few people living on Mars.

Well...first we need to get up from being a Tier Zero civilization to a Tier One or Two.
[QUOTE=Swilly;22913987]Well...first we need to get up from being a Tier Zero civilization to a Tier One or Two.[/QUOTE]
Well we are getting close to a Tier One civilization I think. We are testing public space travel so far with these companies launching rockets and making plans for space. We are working on changing our power source from a limited one to a almost unlimited one through Nuclear Fusion. New technologies such as nanotechnology, the effort to expand the human race, and of course the upcoming opportunities for space colonization, I'd say we will be Tier One by 2100 - 2200, give or take.
Now Swilly, correct me if I am wrong.
The dude's name is john carter? LOL. John Carter of Mars ftw.
