Perhaps, but if I have a schizoid embolism, it won't matter anyway.

Not unless you turn on the reactor and give these people ayah.

Are they saying we couldn't put CO2 on Mars?  Because we're the farking experts and CO2-ing up an atmosphere.

Guess I won't be getting my ass to Mars anytime soon.

Well, subby, you can forget about terraforming it to look like anything EXCEPT earth, because that's what terraforming means.....

You want to keep an atmosphere?  You gotta start with a magnetosphere.  That means you somehow gotta restart the core and get it molten again.  That's juuust a tad further that current technology reaches.

UberDave: Are they saying we couldn't put CO2 on Mars?  Because we're the farking experts and CO2-ing up an atmosphere.


Mars doesn't have enough gravity to hold much of an atmosphere.  It is currently in the process of losing what little atmosphere it does have.  In order to terraform Mars, they'd have to find some way to increase its mass and thus its gravity in order to hold onto more air.  Otherwise it would be like trying to fill up a spaghetti strainer with water.  Also there is very little magnetic field on mars because the core is for the most part solid, thus not much electromagnetic effect generating a field to bend solar radiation and cosmic rays around the planet.  Mars does have magnetosphere, just not enough of one to be effective.  As it is, Mars could be colonized but not terraformed, at least not with current technology.  Thus colonists would all be living underground or on the surface in reinforced and radiation proof domes or other sealed structures.

Terraforming? Hah. Just build some shopping malls, liquor stores, sports stadia and ugly truck/SUV dealerships and it'll be just like 'murica.

I heard a suggestion to actually place a device at a Lagrange point between the sun and Mars that generates a magnetic field. Supposedly could provide the shielding needed but without needing to have a magnetic field which was the size of a planet.

The TV show Defiance.

It was all about aliens fleeing to Earth and screwing it up via accidental terraforming, and then all of the species having to live together.

That's the lovely Stahma Tarr.

Well that makes sense, besides we're to busy terraforming Earth into Mars at the moment.

Are they looking at having a near pure CO2 atmosphere?

UberDave: Are they saying we couldn't put CO2 on Mars?  Because we're the farking experts and CO2-ing up an atmosphere.


That CO2 (or its components) was already here, we aren't creating it, just moving it. And not even close enough to fill mars's atmosphere.

Maybe there will be abiogenic oil and we could extract the oxygen tied up in surface minerals with solar to burn the oil.

As NDGT put it...

"Whatever the cost is to terraform Mars and transport a billion people there... Use that technology and funding to make Earth more like Earth again. Whatever it takes, we can save this planet."
 
2017-04-18 12:26:17 PM  
Landing humans on mars would be an amazing achievement and zI hope we do it.

That said, living there or dreaming of a colony or terraforming is a colossal waste of anything that can be wasted.

Let's get on with the real future - getting some heavy industry infrastructure in low earth orbit so we can do to some asteroids what we did to West Virginia. Space industry and factories and mining will happen. A colony on Mars is dumb. It's too farking far away. Too inhospitable. Oh, and there's nothing there we want or need. So... what's the point of it again?

It has gravity. As it turns out that's pretty important to your physiology for human life anywhere off of earth for extended periods of time.

IMHO we should start with a moon base before we bugger off to Mars though.

Let's just take all the extra CO2 we have and move it to Mars!  Easy Peasy!
 
2017-04-18 12:39:09 PM  
Terraforming Mars as a short term practical goal is unworkable.

Maybe in 600 years deep sources of carbon could be found and exploited or lots of comets could be crashed into the surface. Then again at that time it may be that living on the surface of a planet is regarded as silly and economically stupid.

Gravity can be simulated with spin. The main point being there's no real compelling reason to BE on Mars for a long time and getting there and establishing a semi-permanent base would be prohibitively expensive. There's no reason to be there except to be there. There's nothing wrong with a purely scientific endeavor but at the end of the day the capital needed to do this shiat for the long haul will follow some purpose beyond pure science. Like building heavy industry in orbit. The only reason to go to Mars is to go to Mars - very cool but not sustainable. Unless you build a bunch of shiat in earth orbit first.

You'd need some kind of bacteria that not only thrives in Mars's harsh conditions, it releases CO2 as a byproduct. Pretty tall order.

CNichols: Was I being lied to about the ease of making Mars more Earthlike?

[img.fark.net image 225x225]


I'm gonna go with yes?  The reason Mars isn't earthlike already is because it has no magnetic field.  Even if we did terraform it, any atmosphere we create would just be ripped off the planet eventually.  The solution to this problem involves magical technologies that don't exist.

1. Suck out a shiat ton of C02 from Venus
2. Transport it to Mars
3. Both Mars & Venus are now terraformed

I don't really care about the details, I just want mining colonies on Venus like Cloud City in Empire Strikes Back.

Yet another reason why it's dumb to be thinking about being there for more than a short stay. Getting to Mars would be a colossal achievement. Staying there for any length of time would be a waste of time and resources. Spend the money and attention on the asteroid belt where there is a potential future and shiat we can use to make more shiat. Generations from now, after we figure out how to do shiat and make stuff in space and stay there for a long time perhaps knowledge will have progressed to the point there is some potential reason for being on Mars. Right now it's just a somewhat pointless distraction that's attracting dollars and attention from the less sexy but far more practical goal of putting some industry in low earth orbit. Also a farking nearly impossible dream... yet far more realistic than a mars colony or terraforming. We can't terraform shiat and it's pointless to even imagine it until we develop some infrastructure outside of the gravity well.
 
2017-04-18 01:16:30 PM  
Well, I'm convinced.   I mean, it's not like we could take oxygen and carbon trapped in the geology of mars and make new CO2...  oxygen and carbon are only among the most abundant elements in the universe.   And, if by some miracle all the carbon is gone from Mars, well... it'd be impossible for us to launch rockets to Mars filled with carbon-rich materials since we're clearly not looking into ways to dispose of our excess atmospheric carbon.

If we can get a magnetic field in place on Mars (internal or external), and kick start some greenhouse events... we could easily have people, plants, and animals in domes within a few decades.   It'd be 200 years or more before the surface was habitable, but radiation domes are a start.

KingRamze: it'd be impossible for us to launch rockets to Mars filled with carbon-rich materials since we're clearly not looking into ways to dispose of our excess atmospheric carbon.


Wow. Let's say we decided to commit suicide on behalf of the entire species and undertake this absurdly stupid idea. Ten farking thousand rockets wouldn't begin to make a farking difference. This is dumb in more ways than I can count and you should stop thinking it.

If we can get a magnetic field in place on Mars (internal or external), and kick start some greenhouse events...

You should throw in world peace and a unicorn cavalry while you are wishing for impossible shiat we won't be able to do a thousand years from now.

Not *NECESSARILY*.  As long as you can replace it as it's being lost, you're OK.  I can't recall the actual calculation, but I seem to remember that it would take several hundred years for natural solar wind erosion to cause Mars to lose a thick atmosphere.

JohnBigBootay: You should throw in world peace and a unicorn cavalry while you are wishing for impossible shiat we won't be able to do a thousand years from now.


Actually, if we really wanted to, we could probably breed unicorns after a concerted effort through DNA manipulation of horses.  Once you've got the horns, well, cavalry is just training.
 
2017-04-18 02:00:02 PM  
I don't know the rate of atmospheric loss, but if it isn't too significant it wouldn't matter. We could replenish the atmosphere as it escapes for a while until we come up with a better solution. If half the atmosphere would escape in a millennia, that's bad geologically but alright on a human timescale.
