Total meme.

It'll be easier and faster to just change ourselves to the environment than the other way around.

>>9018968
What's that got to do with what I just said? Anyway you should really specify the population. It's just poor form not to. E.g, Negroes, Arabs, Jews.

>>9018900

The atmosphere of Mars consists primarily of carbon dioxide so it's totally possible to convert it into a breathable atmosphere through photosynthesis. Only question is how we get ammonia on Mars to sustain heavy plant growth as is depicted in the pic.

>>9018963
>implying the gas will just stay there despite low gravity and lack of magnetic field

>>9018976
>Magnetic field has anything to do with an atmosphere.
>The carbon atmosphere it already has is an illusion.

>>9018979
are you being serious right now

>>9018963
By the time we terraformed Mars to have a livable climate cyborgs will be a thing.

The advantage of cyborgs is that we can easily swap out the brain for a body more suited for that specific environment. you can literally live wherever. Mars, Europa, Titan, Space stations, Earth's oceans, ect...

>>9018997
Well first we need engineers to stop being such niggers and work towards integrating biological systems.

>>9019000
It's not easy anon. But even if it takes 100 years it's still faster and more flexible than terraforming.

>>9018974
>>9018979
The pressure at the surface of Mars due to the atmosphere is 0.00628 atm
Good luck if you think that's enough to just slap some plants on and wait

>>9019005
What is a pressurize greenhouse?

>>9018974
The problem with Mars's atmosphere is that it is too thin to do anything useful, at 0.6% of Earth's pressure. Even if you could produce enough oxygen to be at level that are breathable, you would also need remove the excess CO2 to levels where breathing is safe. To do this, almost all of the CO2 needs to be converted, but doing this would result in an atmosphere that would kill everyone through oxygen toxicity in much less than a year, ignoring the dangers fires present in that type of environment.
Regardless of what happens, a significant quantity of filler gas (like nitrogen) would be required to make the atmosphere breathable and safe.
Once you create this atmosphere, you then have the issue of retaining it. Mars has evidence of liquid water existing at one point, which requires a sufficient atmosphere to maintain. This, however, would have been lost to solar wind, which affects Mars in a much greater way than Earth due to Mars's lack of a sufficient magnetosphere. The solar wind isn't redirected around the planet, and so erodes at the atmosphere, slowly tearing it away into space.

>>9019059
You may as well make a colony on the moon with that type of logic.

>>9018900

I don't know if you really can

>Lower gravity means that the atmosphere will just simply fade away
>No magnetosphere will mean that the sun... will make the atmosphere disappear
>Low pressure means that you will have to introduce gases on planetary scales to increase them to up to 1 atmosphere.

All the solutions to these problems means that you need the ability to harvest the energy of the sun.

Fully a meme.

I don't get why people assume that colonizing Mars = terraforming. It would be much easier to just build some underground tunnels and put Oxygen on them only where there are humans, like isolated cities or some shit.

>>9018900
Mars doesn't have a liquid core so you'll have to find some other way to deal with the intense radiation.

>Bring a really thin drillbit with me to mars

>>9019283
You'd need to bring your own nitrogen to make the gas breathable and safe. You'd also have to create a perfect seal along the entire city, since any leaked nitrogen can only be regained from extra-planetary sources.

>>9018900
Why not just terraform areas of the earth

>>9018900
I hope not.
Escaping to space and hopefully to another planet (Mars in this case) is humanities only hope for existential longevity as a safeguard against catastrophic environmental failure or an impact event.

>>9020233
once we know how to do that we can do it anywhere

>>9018900
No, and you will live to see it.

>>9020233
Drop in the right mix of plants and you can do it. Ecological engineering is a thing, and when we commit to it, we do it better than nature does.

>>9018963
?
Do you not understand how massive amount of shit you need to do to terraform anything?

Instead you can just adapt humanity for living in vacuum, we have not seen anything close to what a spacesuit could actually be yet.

It´s impossible. Mars has 10% of earths mass and no strong enough magnetic field. Even if you achieve to create an earth-like athmosphere the reduced gravity and unfiltered solar storms will just blow it away.

>>9021168
>and unfiltered solar storms will just blow it away.

The question is how much time it would take.

1 million years for the universe is nothing.

If we manage to get out of our own gravity well in any significant capacity, the last thing we want to do is drop down another one.

We need to understand how Mars lost its atmosphere. Did ijt take millions of years or did happen over a few hundred years after Mars's internal magnetic dynamo shut down?

Second major issue to figure out, how quickly would Martian regolith sequester free O2? If it happens quickly then any photosynthetic life we introduce will just as quickly rarify the atmosphere. But at least this has a costly workaround. Giant moholes into the crust deep enough to get down where it's still hot will release CO2 into the atmosphere. Or we just remove the CO2 from the Martian crust ourselves by melting Martian rock in huge forges (very energy intensive) or maybe use a solar mirror to focus into a death ray that can turn whatever Martian rocks we point it at into lava.

Does time dilation play any role in the speed at which Terraforming can be completed?

>>9021393
>very energy intensive
we have nuclear power anon

>>9021443
Fissile material is practically finite and the energy we would waste simply burning rocks all day in huge nuclear furnaces could have been used for virtually anything else.

The death ray idea is less wasteful though because simply focussing a mirror that would otherwise still be in orbit reflecting more sunlight onto Mars is in effect killing two birds with one stone.

>turn recycled aluminum cans into folded up solar sails
>only launch supplies bound for Martian colony into Earth orbit
>unfold FUCKHUGE solar sail
>solar sail slowly carries supplies to Mars
>supplies reach Martian colony and sail is placed into orbit around Mars
Bam, I'm being Green, saving money on rocket fuel, and terraforming Mars all at once.

>>9021457
>e death ray idea
>>>/x/

>>9018900
It's a meme. Why don't we just do it to Earth and fix climate change that way?

>>9021463
If anything we might use the solar sail as a giant energy collector to power the colony. Actually boiling rocks to give off CO2 would require several orders of magnitude more energy.

>>9021408
Time dilation is only an issue at relativistic speeds.

>>9021393
You're ignoring the fact that you would need to convert almost all CO2 into O2 to make the air breathable, and that high oxygen environments are incredibly dangerous with anything flammable and are toxic to life. A diluting gas such as N2 is needed (50% O2 is when toxic effects begin to become an issue), and there is no practical source large enough to solve this issue.

>>9018902
fpbp

At the current rate that technology is advancing, this will become rapidly feasible, and should be a desirable ambition as opposed to an automated robotic society where we give up trying to sustain organic lifeforms

>>9021562
Titan and Venus have plenty of gases to harvest
if we have the industry to be even remotely capable of terraforming mars at all, we have the industry to harvest them for such efforts

>>9018902
Why? Mars has the same ultimate time limit as earth.

the sun going red giant can be halted by stripping mass from it
you pump matter out, remove what isn't hydrogen, and dump the hydrogen back in
lots of materials to build with, and more time is bought

If we had the tech to do that we'd be colonising all over the place

>>9021542
Early on pointing the mirrors at or near colonies to increase temperatures locally, power solar collectors, and influence weather conditions would be a very good idea. However if you are seriously trying to terraform Mars then we need FUCKHUGE mirror arrays. We are talking about mirror arrays that are millions of km square, to the point of if focussed they would melt the crust. Imagine all the sunlight that hits Texas being focussed onto one city block.

>>9021562
>breathable atmosphere
Slow the fuck down. We are nowhere near discussing that point yet. You are discussing how to make turboprop planes before we've even mused on whether simply getting a combustion engine off the ground is possible.

The first goal of terraformation is temperature, the second is atmospheric mass, the third is atmospheric composition.

>>9021594
Not really. To "even remotely terraform Mars" we just need solar mirrors. Solar mirrors are much easier to produce than it is to haul a significant amount of a world's atmosphere across the solar system.

We should make a tube all the way from Earth to Mars so we can keep pumping all our CO2 there. That way we'll stop global warming, and we'll make Mars habitable at the same time.

This isn't all that difficult to do. A tube made of smaller carbon nanotubes can easily maintain its structure while the distance between earth and mars varies. The tube can be placed above the two planets so there's no risk of tangling when the planets go around the sun.

>>9022567
Do you have any idea how fucking long this tube would be ?

>It's humanity's only hope
>mfw he drank conman Musk's coolaid...
We'd be better off focusing on mining asteroids and developing infrastructure like a space elevator than terraforming Mars. Economically this makes more sense and which ever country dominates space first is literally going to be the ruler of Earth. You literally have the ultimate high ground and can prevent anyone else from having it.

>>9021743
strangely enough, it doesn't actually take super high tech, we have the tech to do it, and lots of other shit right now
it's just the lack of funding and industrial base that is preventing us from doing it

An industrial foothold in space is a necessary first step to terraforming Mars, dumb dumb.

Step 1 would be to recreate Mars' magnetosphere.

You can't even have a fucking atmosphere without a magnetosphere.

I guess my argument is why is Musk and every other Reddit-tier science enthusiast only shilling muh Mars colony?
I appreciate they have to capture the public's imagination but a more productive approach would be to shill to the political and business elite about the potential profits of mining a trillion dollar asteroid and refining those resources in space. That coupled with the potential military applications should draw billions in government and private capital into developing the technology required to begin moving humanity off earth.
But no don't talk about that, keep larping on about my unsustainable dome houses on Mars while we sit around for a couple of million years until Mars becomes as inhabitable as the Sahara desert.

>>9022853
Your link if anything proves Mars DOESN'T need an atmosphere to be terraformed.

The article says Mars looses atmosphere very slowly and only lost its atmosphere because the Sun used to be a lot more active.

>>9018979
A satellite at the sun mars l1, with a massive super conducting magnet. It couikd generate a larger enough mag field to shield mars.

Said shielding would allow the atmosphere to naturally build back up.

>>9022938
Fucking hell. You sound like you're twelve years old. I couldn't get past the first sentence. Learn to communicate like a functional adult.

First you need to pump about 100 trillion trillion kilograms of molten iron into Mars' core to create a magnetosphere

>>9023436
Actually you don't need to.

>>9021621
>sun going red giant
The the time the sun goes red giant, if we continue technologically advancing like we are now, we'll just make our own artificial planets that don't need suns or make our own suns ourselves. My old astronomy teacher would say that it doesn't matter what happens to humans because we'll be wiped out in 5 billion years anyway. I always thought to myself that in >billions of years we'd be so widespread throughout the galaxy like a fucking weed, our sun would be a fucking memory anyway.

>>9023516
that's a big if, just because we have advanced so much in the past +100 years doesn't mean it will just continue like that forever until we are some kind of gods
