Should Mars be terraformed?

ya, here was where it was said... i actually dont know if this statement is true or not, i just made my account and dont know anyone.

and before you bash me on how it says most likely a couple hundred of years... i know it says that

The idea of terraforming Mars is just plain bonkers. It's one of those ideas that comes from people who have been overexposed to scifi and have lost their grip on reality. It's only one step down from travelling through wormholes in space or making people immortal. Forget it!

But if you can't forget it, produce a cost estimate.

I never said we were going to... It would cost trillions of dollars and we couldnt ever get the money to afford it. What im basically saying is that it would be nice if we could do it.
What i was saying earlier was only to show my view on saying that if we could afford it, and could in fact do it perfectly, then it should be first priority.

No, because to live in a 100 years from now you have to survive first.

We'll talk about that when it's possible

Of course it can be done in theory. And I don't mean make it like earth, but just habitable enough to grow plants on the surface for example, while we live in domes or underground.

 

I saw a few programs on Discover or NGC in which scientists estimated that it could one day be done in a couple of hundred years, maybe in a shorter timespan.
Of course this was in theory, not a practical estimation.

 

But if you know that your not going to live at the end of the 100 years, wouldnt it make it just as important, and therefore just as important of priority as survival?

Look at my later comment... your just repeating what i already said

 

I thought that we were only talking in theory??? Im not saying as fact, i know its just theorized

My comments may have been confusing before because i may have worded them wrong, my bad... But ya, i know its all theorized currently

 

Ok

Draqon isn't talking theory..

I don't remember the details though, sorry.

 

the details from the Discovery show?

 

I don't remember how they theorized it should be done. So yea from the Discovery show, although it could have been on NGC.
It was some time ago..

Ya, im sure someone will talk about it eventually on here (im not saying your a lier by the way, i believe you

Thanks.
I'm admitting that I don't know the details so people can choose to ignore it.
It's just something I remember, not an argument.

 

ya, i know what you mean

 

Wouldn't the first step need to be increasing the gravity to the point that a thicker atmosphere will remain? How would we do this? Green moss or lichens planted on the polar ice cap 'could' release oxygen and nitrogen but once that bleeds of into space/
Personally I like the idea of terraforming, assuming that we learn enough to not make the mistakes we have on earth and that the technology to do so becomes possible.

 

We need to pump massive amounts of greenhouse gases into Mars's atmosphere.
Mars once had a thicker atmosphere and it stuck for quite a while..
We may have to replenish it every few decades, or maybe only every couple of thousand years..

Then we need to release blue green algae into it, again in massive amounts.
If there's not enough water we'll need to add that to the planet's surface as well.
Probably, after I couple a hundred years the atmosphere will be habitable for some plantlife.

 

The problem is that you run into the problem of controlling gravity, which is so far out of our league that i doubt if people are even working on controlling it

 

For what purpose ?

 

i was replying to this part, forgot to quote

 

mars also once had a molton core ( or so I've read) and a magntosphere. I agree that global warming is the answer for mars (and I suspect it always will be). Question, where are we going to get the massive amounts of greenhouse gases needed and how will we transport it there?
