Venus is probably unterraformable. I wouldn't try, at least.

We just need to get a shitton of hydrogen back into Venus somehow. Collect it from Jupiter or Saturn or something. Then we setup some artificial magneosphere or some other way to protect the atmosphere from the sun.

>>2351

You could try living in the upper atmosphere if you could construct such a monstrosity that wouldn't corrode or melt.

>>2381

In the high altitudes in Venus, it's actually rather cool, I hear. But Venus is fucked man, we won't be able to fix it, not in out life times anyways. Mars is our best bet, but how the hell would we bring back its magnetosphere? It still has traces of it left, but even so, it's more or less gone…

We can move ceres into mars orbit and try and position it into becoming a Moon, this can cause a Dynamo effect and causing Tidal forces hopefully helping to warm up the core and maybe restore the magnetosphere, we could also export all that damn Ice on Ceres to mars if mars has too little. Though I'm not sure if Ceres has enough mass…

However if we have a system of "dump all the waste from mining asteroids here" then it should gain mass pretty fast.

>terraforming

Won't happen in our lifetimes. Probably won't happen until English is a dead language at least, and that's assuming all Earth governments unite and work on it with Apollo program-tier devotion for centuries. Which they won't.

And that's feasibility. If you consider the "okay, we can terraform Mars, but it still cheaper and easier to just build closed-system bases and space stations" angle, you realize that you're better off waiting for time machines to be invented than terraforming to happen.

>>2468

It's called Bio engineering and using efficient means to warm the planet, bacteria/plants will do most of the work for us and it may be a long time before it's fully terraformed but it may not be as long as we think, about 450 years before Humans can breath on the surface, and It's going to be motivated by Pilgrim like motherfuckers trying to build their own countries and the like, and most of the "terraforming" will be Just warming the planet to an acceptable level then throwing some fucking bacteria out there and as time progresses just add more shit, so if you think about the resources necessary to Build all those space habitats, throwing asteroids, building some huge mirrors, and releasing some Hydro-fluro carbons from the martian soil would be easier than whats needed to keep fueling the space stations and too keep out radiation and how vulnerable they are for long term civilization, don't get me wrong I believe we should have space habitats but for a new branch of Humanity Planets are the way to go.

>>2472

>about 450 years before Humans can breath on the surface

Hilarious.

Just convincing someone to start this project alone would take that long. Good fucking luck. Keep dreaming spacefag, I'm sure you'll get to explore the universe any day now.

>>2485

Your not convincing anyone do to anything, the scientists/colonists on mars are going to be the ones doing it.

>hurr no ones gonna want do it

Yeah people also said that the Continental Congress would never build any nation wide roads, and That the Egyptians said no one could build the Pyramids. If any large infrastructure were to be built on mars it would only be a matter of time before the Governments would start terraforming, the only problem if there are Mars Conservationists, pretty much anti-terraforming because they want to preserve the surface of Mars.

And Like I said only about 40 of Human intervention is needed to start terraforming the rest is up to bacteria and fungi.

>>2494

What a ridiculous attitude. Just because someone once said one thing wouldn't happen and it did, doesn't mean every inane dream you have is now guaranteed to be reality.

>building a bunch of roads

>on the same level as completely changing the climate and ecology of a planet

>we can barely even send tiny rovers to that planet let alone humans or bulk cargo

>the last vestiges of the space race are dying

Hey, maybe Mars One would do it, right? They once said flight was impossible, that totally means Mars One will succeed!

>>2501

No but I'm saying that such things can be done, and if such things are a commodity, such as the Suez, Panama, and Erie Canal once thought to be impossible when fueled by the though of prophet will be completed in an instant.

With the rate technology is advancing In about 60 years or when asteroid mining becomes feasible is when you'll see people walking on mars, and about 130 years after is when terraforming will more or less start

>"lol we can hardly send rovers there xD"

>implying technology isn't rapidly progressing

>"lol you can't change the ecology of a planet"

Except we are doing that now

>inb4 /pol/ says we aren't

though I do agree Mars One is retarded in the fact they want untrained retards who can't fix a flat tire to go to Mars

>>2502

I doubt people seriously believed that the Suez canal would never be built. It's a question of when and how much effort it will take. Note also the direct economic benefit of something like the Suez canal relative to its cost.

You will note I am also not saying terraforming will never happen. But it won't happen in your lifetime, and not in the near future - the point at which it becomes feasible is so far into the future that it's pointless to even talk about it, since it's clearly a future far beyond our comprehension.

>With the rate technology is advancing In about 60 years or when asteroid mining becomes feasible

I'm curious, how do you arrive at this figure? Why not 50? Why not 70? Why not 120? I mean, 60 is pretty precise. How do you calculate this? Can you show your work? Is it just because you are 20 and your expected lifespan is 80, so that leaves 60 if you're gonna be around when it happens?

And the 130 years, where do you get that?

>>2505

No, its about when at the current rate technology is progressing when people are going to do more on mars than just walk around, And I do not expect it to be completed in my lifetime of course, but it will Start in my lifetim (hopefully, unless moral faggots try and pull the "ur just gonna destroy murs tuo")

But what we could expect is asteroid miners hurling the unwanted junk from asteroids at Mars, and perhaps even a few redirected comets thrown at mars to get some fucking heat and water on that thing.

The 130 years is about when the releasing of greenhouse gases and the Bacteria start making it where there is enough oxygen in the atmosphere that with a co2 filter you can breath and won't need a pressurized suit or heating system (for the most part).

>>2507

You still haven't explained where you pulled 60 years from.

>>2516

It's an estimate from the heat made by humans artificially producing Co2 and putting into the atmosphere multiplied by the far more potent Fluro-Carbons. By then in the equatorial zone should be able to harbor extremeophile bacteria, they may be engineered to be black so more of the suns rays stays on Mars.

>>2518

Can you please show the calculations?

>>2519

Nigger I said it was an estimate, it may be 50 or so years off at most but because the world temperature rose around 7 degrees in the past 150 years, multiply that by 30 or so and you get 50-60 years with A rise in about 70 degrees, which added to the Martian atmosphere would warm it up melting the CO2 ice and thickening and warming the atmosphere enough that most extremophile life forms can survive, infact if such conditions were to occur even complex plant forms could survive on the surface, moss, algae, lichen. And if chucking asteroids were to be made accurately then chucking a decent size one at the poles would do all this in a matter of decades.

>>2520

If it's an estimate then show your approximate calculations. What's your input data? What's your equation? What's your 95% confidence interval?

You said 60 years, not me. Now explain yourself.

>>2545

Forgive me a '''Rough"' estimate that does sound really autistic but I got it through basic multiplication and addition [spoiler] Still no reason for you to be butthurt though [/spoiler

>>2553

I'd worry more about your rectal discomfort. My hole isn't the one that just had 60 fucking years pulled out of it, you know.

>>2554

Why so salty?

>>2554

>nu uh, your the one thats butthurt

Come on man.

Would it be possible to Paraterraform The moons of Jupiter or Saturn?

Also one guy said something about having nuclear reactors down in the subsurface ocean of Europa and supply power to UV lamps that way while also using native water to cool the reactors, perhaps letting some of the areas be warm enough and with UV lighting be able to harbor algae and later algae eaters.

>>2581

i think it would take more energy than we could generate using nuclear reactors alone, given the finite amount of uranium/plutonium and tritium/deuterium for fusion versus the surface area and altitude gradients we'd need in order to sustain a proper magnetosphere ion trap.

>>2584

Forgive me, I only meant a small art of the ocean would have the UV lighting, just enough that some ocean flora and algae could survive. If of course there are no native lifeforms.

Well, I suppose this counts as terraforming, or at least world hacking:

What are some steps that could be taken to cool the earth and/or change things wrong with it, I think something along the lines of manufacturing billions of bio-degradable white plastic floating bobbers, constantly create them and all the color white reflects more light and with that light comes heat, or in more advanced terms more protons reflect off the surface, with billions of these in a group after years the earth will get cooler and the north pole will grow back its glaciers and then stop producing that shit because the polar ice reflects enough at that point that anymore does more damage then good,.

And yes I know the the UN that shit would never happen but I'm just saying on hypothosis and reguarding already known data it could make somewhat of a dent.

Bump

>How the fuck would Venus be able to be terraformed?

Shitloads of water and calcium. The whole thing would also have to be catalysed because making limestone that way would probably take a lot of time.

>>2749

easier just to have automated Robots create a sun shield from Aluminum, maybe if space elevators become a thing we can pump all that fucking CO2 into space.

>>2817

>maybe if space elevators become a thing

They won't.

>>2862

>maybe if space elevators become a thing

have fun dealing with a situation comparable to balancing a pencil on a soccer ball hurtling through the air.

>>2862

>>2863

samefag please

if done with precise mathematics they're…. Possible, but in 100-1000 years with the need for them they might be able to create something similar, some think a Laser cable would be better (don't fucking ask me how that works), but anyways I think Fusion powered Rail guns that launch space shuttles would be better.

how would getting a Mar's thats warmed up to have a proper Biosphere without shit fucking up?

>>2626

>or in more advanced terms more protons reflect off the surface

>protons

Protons??

>>2865

>fusion powered rail guns

Why not just a massive series of electromagnets that launch you to space. Way cheaper and doesn't sound like a huge disaster waiting to happen.

>>2900

>Why not just a massive series of electromagnets that launch you to space.

That's what a railgun is. And nuclear fusion could be a viable form of power generation.
