Why does it have to remain so? It is not a virgin environment, it is a sterile enivornment.

When Mankind can prove it can live in equilibrium oni Earth, then it can spread elsewhere.

How do we know what "equilibrium" is? We are just as likely now to be living in "equilibrium" as we are to not be living in "equilibrium". Every creature (and plant) on this planet has an impact on the environment. Some more so than others and everytime one creature or plant becomes dominant or has a larger effect that others a new steady-state is eventually reached.

It's been speculated for many years to reproduce gas emissions on Mars as we do on this planet. The atmosphere was thicker on Mars then it is now; yet you have to go back to the problem that caused the atmosphere to thin in the first place. As it turns out, the core of the planet slowed down or event stop spinning causing the magnetic field to disappear.

Unless the core spins to shield the planet from the solar winds then anything done will only be temporary. The sun will simply blow off any thick atmosphere. Alas a pipe dream to teraform the whole planet unless you take some ideas from the movie Space Balls.

Global warming the key to life on Mars

Tim Radford, science editor
Monday February 7, 2005
The Guardian

US scientists have thought up a new way to create a second home - by warming up the atmosphere of Mars.

Mars - which used to be warm and wet - has an atmosphere rich in carbon dioxide. But because the red planet's atmosphere is so thin, the planet is now freezing cold.

But Margarita Marinova, of Nasa Ames research centre in California, and colleagues report in the Journal of Geophysical Research-Planets that artificially created greenhouse gases could set the Martian climate simmering. "Bringing life to Mars and studying its growth would contribute to our understanding of evolution, and the ability of life to adapts and proliferate on other worlds," Dr Marinova said.

"Since warming Mars effectively reverts it to its past, more habitable state, this would give any possibly dormant life on Mars the chance to be revived."

She and her colleagues created a computer model of the Martian atmosphere, and tested it with a series of fluorine-based gases. They found that a gas called octafluoropropane could begin a process of global warming on Mars.

This would take hundreds or even thousands of years. But since the raw materials already exist there, some future space mission could start to turn up the heat in a world frozen for at least 2bn years.

Saven Marek (739395) | more than 9 years ago | (#11598017)

It's still debatable whether or not global warming can even happen with the amount of gas we are putting into the air.

And so how would you expect that to make any difference on mars? You would be have to be sure of the results to start. Until we know we are global warming here I say we hold off and not try experiments over a whole planet.

Anonymous Coward | more than 9 years ago | (#11598102)

You're right about "pop science". There's little debate anymore about the effects of CO2 on global temperatures, except among non scientists (i.e. Pop science). The only debate is, "Does it matter?" You can believe what you hear on from Pop science places like FoxNews, but there is a dramatic change going on and CO2 is the only explanation that's been found to fit.

Multiple methods (2, Interesting)

soab (55718) | more than 9 years ago | (#11598088)

Nasa is actually considering multiple methods for heating Mars. These include: nuclear dust over the south pole (dark dust attracts sun energy which melts south pole), Methanogens (can survive Mars and produce methane), Space mirror (heating the southpole to melt), Drilling into Mars to use it's geothermal energy, and a few other even crazier ideas.

There is a lot of theories out there and some are experimental. We can't expect success on the first try so sending multiple attempts at once will most likely be NASA's approach.

They got a mule they call Sal
Bulldozing up canal walls
They're gonna tap that icecap too
When they do they're gonna make that green map blue
The weather is finally getting warm
And the weather is really getting warm
Don't know how this whole thing started
There was a cloud and then it parted
Don't know if I'll ever go back
That's how I felt when I left that tarmac

I sure hope Khan doesn't find out about this plan. Although, maybe if he does, we can send the dead scripts from Enterprise to the budding planet and resurrect a franchise ...

This is totally irresponsible work by NASA. Climate scientists should know better than anyone the lesson of our imminent climate change crisis. Human meddling with astoundingly complex systems like planetary climate is arrogant well beyond our competence, and predictable only by the law of unintended consequences. Screwing with Mars' atmosphere when we're just beginning to admit that we've already screwed up ours will nearly certainly make that planet harder to "manage" as it becomes more necessary to our human evolution. Humans thrive only in a very narrow band of climate parameters, out of a vast range of possible climates. When they spend a century shifting Mars unexpectedly into a less mutable climate stasis, that is just as inhospitable to human life as it is now, but a different configuration, it will take even more centuries to undo the damage, if even possible. We're just not ready for this kind of work, if we ever will be in the foreseeable future - and the stakes are too high to fool with.

I don't really understand where this so called "scientists" get their mad ideas from... Moral issues aside, just in case you'd like to try, do you realize how much gas would you need? Well a lot. That means:
1) collecting, transporting, releasing the gas into martian atmosphere would take an incredible amount of energy. It should be debated if such energy is at our own disposal in the first place. Keep in mind: taking the gas from one planet (as we don't have nebuale in here ;) ) means defeating the planet own gravity field, then there's the trip and there's the release... mmmh... But let's go to number two
2) One of the reasons mars has lost most of its atmosphere is that it hasn't got enough gravity pull to withstand solar wind. Atmosphere gets (slowly that's for sure) drained away every minute. So you don't want all of your work to go wasted in space do you?
3) last but not least. Where to take the "gas"... I really hope you're not talking earth right? We already did a lot of bad things to this planet, taking away it's atmosphere is just the worst of many bad ideas. And to those thinking "hey we'll just take pollution away" let me remind you that we're talking about phisical matter. transporting mass to one object to the other.. What would that do to our planet? less gravity pull?
Anyway, why am I talking about this? it's pure nonsense. Not even science fiction.

That is impossible.

Global warming is nothing more than a fantasy cooked up by left wing kooks..

Why would it work this time? (2, Interesting)

This post is definitely meant as more of a question than a statement, as I am pretty ignorant of geophysics and the like.

But could someone explain to me why scientists even consider the idea of trying to artificially create a new atmosphere around another planet, and why they think it could work?

The thing I am not understanding is that if Mars is thought/known to have had an atmosphere in the past, and doesn't anymore, clearly there are factors beyond our control that would just cause a new atmosphere to eventually disppear too, right?

The original atmosphere on Mars must have disappeared due to factors such as boiling away, not enough mass to create a strong enough gravitation field to retain it, or perhaps being blown away by solar wind because Mars does have a magnetic field like we do here to deflect it, etc. (By the way, I don't even know if these are real situations that could occur, I am just making them up as examples of things beyond our control that seem to me that logically could maybe have caused the previous atmosphere to disappear.)

So again, this is not a statement but an honest question from someone who doesn't get it- what is different about mars now than a hundred million years ago that makes scientists think it would work now?

Ah, it seems that while I was writing my original post, someone was addressing that very issue above in the thread....

Don't you know? The US is evil now. It happened when GW got re-elected. So fuck our environment, fuck Mars, fuck Europa, and Titan....well, its being renamed Haliburton. Deal.

There's a huge difference between NASA proposing warming Mars and a NASA scientist making the same proposal. While I'm on the topic of this stupid title, it's "NASA", not "Nasa".

A Kim Stanley Robinson (SF writer) short story which he later expanded into 3 novels (Red/Green/Blue Mars).

Covers this is a believeable and seemingly plausible way...

One of my all-time favorite SF series, right next to the Gap Cycle by Stephen R. Donaldson and the original Foundation Trilogy by Isaac Asimov.

This was reported in the movie Total Recall years ago! We just need to get Arnold there to turn on the alien machinery under the surface to melt the ice and produce breathable air in minutes!

so.. we start global warming on Mars.. next thing we know, the Martians attack!

I bet yeh they haven't thought about that yet..

So whens the global vote on this gonna be? There _is_ going to be a global vote on this right? Ya know democracy and stuff?
