But whats the point of making it warm if you cant make the air breathable? Also its not self sustaining. At least if it were powered by vulcanism we wouldnt need to maintain it. Take away the factories or run out of energy, and the planet dies again. Doesnt seem worth the costs.
the point is you do both. you make it warmer and breathable. and those factories and energy will run a long time. by the time we are able to do this who knows what kind of energy sources we will be tapping into. Dyson Sphere?
as for being worth the cost...we might think that it is worth the cost if Earth is facing destruction or if we need the extra space or resources.
and maybe we'll do it just because we can. 0 -

Plus, it's still taking too long. With or without the released CO2. And nuclear factories, really? As much as I love NASA for its enthusiasm, building Endeavor costed $1.7 billion. Does a distant alien cousin lending us his cargo ships?
And we cry when they blow the Earth up for the new highway...0 -
Sorry it doesn't work that way. I
Mars died. One of the reasons why Earth has is able to maintain a thick atmosphere is because it has a hot circulating iron core that creates a magnetic field around it. This field deflects solar radiation that would otherwise strip the atmosphere from the surface. Long ago, Mars also had a hot core and a magnetic field. It had a thick CO2 atmosphere which made it warm enough for liquid water to exist. But because its much smaller, its core cooled off a lot quicker and its magnetic field disappeared. This left no protection from the sun. Slowly over time, the atmosphere and surface water was stripped from the surface by solar radiation, leaving behind the cold desolate desert and barely any atmosphere (about 1% of Earth)
So, you cant "add air" to Mars. Its core is dead. Even if you could, adding oxygen might make it breathable but not warmer. Its not a greenhouse gas. Mars needs a thick greenhouse gas environment of CO2 to be warm because of its distance from the sun.
Yeah, geeky.
I am not a planetary scientist. lol
actually that is the way terraforming works...
grabbed one of the first searches i found and there are countless others discussing how to make Mars livable. nobody is suggesting oxygen alone will do the trick.

"That depends," says Marinova, "on how fast we make the gases." According to rough calculations, "if you had 100 factories, each having the energy of a nuclear reactor, working for 100 years, you could warm Mars six to eight degrees." At that rate, to increase the average Martian temperature to the melting point of water -- it's about minus 55 degrees Celsius now -- would take about eight centuries. Actually, it wouldn't take quite that long, Marinova points out, because her calculation doesn't include the feedback effect of the CO2 that would be released as Mars got steadily warmer. "Devising more efficient artificial super-greenhouse gases will also make it faster," Marinova adds
The planet Venus, for instance, has a chokingly thick atmosphere, but no magnetic field to protect it against the wind from the nearby Sun. Every planetary atmosphere is a balance between "sources and sinks." If some process (like volcanism) pumps gas into the atmosphere at a rate that substantially exceeds solar wind loses, the atmosphere will persist. The equilibrium on Venus happens to favor a thick atmosphere."

I'm jumping late on this and haven't read the whole thing but if you're wondering if its worth the cost with what they are doing with space it really is. Economist agree that we get more from the space program then what we put in it, its an investment, by how much they disagree but all agree it does help the US's economy because of the technology that comes from NASA which then private businesses can pick up on and create a business with. If this wasn't at all what you were referring to then my apologies.0 -

I would think that if we have the energy and capablity to fix Mars that we should be able to fix the Earth first. IMO Mars may be a good stepping stone for learning how to live in and explore alien environments, but its no replacement for Earth. Our homeworld is are best most precious resource. Seems like a waste to put our efforts into a place like Mars without fixing our issues here first.
I fully support our space exploration programs, but if NASA announced tomorrow that they were starting a terraforming operation on Mars I just couldnt support it. Priorities.0 -
Wait..
Stop...
There a meteor headed for earth? Why is this not news? WTF!
I know we get near misses all the time. Actually, it's quite scary. But, there one on its way that might destroy us?0 -
Here are just a few products and technologies created by the space program. I used to work on an aspect of the space program, and my father worked on it his whole life, so it's near and dear to my heart. My favorite discovery or invention is Velcro. But, here's the list.

They had to solve so many problems, that they created all these things in the process.
On to the very expensive toilet that NASA had to defend. I love how our VP described it in a meeting once when the controversey over a $50,000 toilet was published in the papers. He said, and I quote in an angry tone, he looks around the room during a silence after a question about a $50,000 toilet comes up, and he says, "has anyone here ever taken a *kitten* in outer space?" first there was silence, then laughter. Of course not, so you can't possibly understand the complexity of the situation. That's one very basic situation that I was involved with. When there's no gravity, the *kitten* doesn't fall down. You have to create vacuum and then we had a problem with it lumping in one spot so we had to create a spreader arm to spread it evenly in the potty holer. I mean, it's amazing the problems you encounter.0 -
As far the OPs question, I would not go to Mars unless my children came with me. If I didn't have children, I be the first in line. I love a good adventure.0

i couldnt support it right now either. but i do support manned missions to Mars right now.0 -
Efffin a right I would! Why not? Dude its Mars!0

Humans will have to go to other planets, and probably soon, to survive as a species. This one will be giving out soon and won't be able to support us for much longer. We have maybe 10 more generations left, out the outside.
Having said that, no I would not go to Mars. I'm too old and uneducated. We need young folks who can have lots babies to emigrate.
i agree with you in the long term but there is nothing to indicate that we only have 10 generations left on Earth.
why do you say that?
I agree with the former. The human species will reach a carry capacity in the future, and space colonization done the right way may help us.
Btw, I think there is an another object in our solar system that already has life. Titan's colorful cracks in its frozen surface could be microbes.0 -
There's always a meteor headed for Earth that *might* hit us. For some reason it's always 20-30 years off. And then when that 20-30 years is up, "Oh, it missed us by about 120,000 miles" or something similar.There a meteor headed for earth? Why is this not news? WTF!
I know we get near misses all the time. Actually, it's quite scary. But, there one on its way that might destroy us?
But yeah, I was actually checking that out after the mention (mostly because someone then dismissed it as a conspiracy theory ... sigh) and there is one that is slated for just around 28 years and scientists are talking about how to potentially deflect it. There is a 1 in 500 chance that it will hit Earth on February 5, 2040.
... Of course, that could just mean it may instead happen on February 6th! Or not at all.
e; Oh, it's called 2011 AG50 -
There IS life on mars...in the form of extremophiles.
Has anyone read the book First Contact: Scientific Breakthroughs in the Hunt for Life Beyond Earth by Marc Kaufman?
it's just sad that while we've found extremophiles, people went ahead and changed the meaning of "life" ... we want "life" as we know it and can utilize, but I say, let's exploit that bacteria. who knows what we might end up with!!
anyway it was a good read. I doubt we'll live up there or transplant oxygen. we're looking at it all wrong.0 -

I was talking about Europa. I hope that nobody holds this against me.0 -
work out in centrifuge producing a gravity effectI wouldn't, there are long term effects of lower gravity. For you and me, after growing up here we'd be fine. But our kids and kids' kids would be much weaker in terms of muscle mass and bone density, and they would also be taller.
Relative to each other it would feel like comparing between two people on earth, but comparing someone who grew up on mars to someone from earth, the person from mars would be fragile and weak.
unless they workout
Working out won't matter, they'll still be fragile and weak compared to us. Same way if life lived on a larger planet, they'd be shorter and stronger.
Hamster wheel on its side.0 -
Hahaha
It's great to be interested in space exploration, but I can guarantee that most of the people who read this thread already support funding those kinds of endeavors. We need some kind of viral campaign that will reach the general (and sometimes uneducated) public before there would ever be the kind of funding necessary to successfully research a way to colonize another planet in or out of our solar system.
And to the girl who said we should worry about earth before we invade another planet.. Face. Palm.
Part of the problems with the general consumption of human beings on earth is that it disturbs the natural ecosystem. Since Mars is basically a dead planet.. there's not very much to destroy. It is actually kind of an ideal situation - but currently, it doesn't matter either way because that kind of advancement is out of our grasp.0 -
Maybe they should be working on curing cancer or idiotism. Something useful.
May some mineral on Mars holds the cure for cancer...0 -

Actually colonization on mars isn't beyond our grasp, it is something that's definitely planned... except the whole thing is funded by a private corporation and it's a one-way trip.

Agreed, that way i can have a dog that breathes fire. lol0 -
I thought this quote from A Clockwork Orange was appropriate... haha
"It's a stinking world because there's no law and order anymore! It's a stinking world because it lets the young get on to the old, like you done. Oh, it's no world for an old man any longer. What sort of a world is it at all? Men on the moon, and men spinning around the earth, and there's not no attention paid to earthly law and order no more. "0
