What's the best way to colonize Mars? Are you also daydreaming

Create a massive solar sheet in space next to Mars and use it to power a series of stations on the surface that convert the current atmosphere to Earth-like atmosphere.

redirect the orbit of an icy dwarf planet and collide it with mars and wait 2 million years

boom mini Earth

>>8021030

>wait 2 million years

Come on we're the masters of creating greenhouse gasses. How hard can it be to heat up the planet in a couple of hundreds or thousand years?

>>8021035
True, but what can we do about it?

wait for the sun to expand and warm it up

>>8021016
make factories producing ozone and carbon dioxide to create an atmosphere and warm up the planet

Build a big canyon and fill it with earth stuff like water, plants, animals
Isolate it from the the dead planet
Focus only on a small region that gives you the best chances
You live on the mars not with the mars

>>8021040
Retreat to Mars where they can't follow us? Or rather, somehow convince them that Mars is an even more attractive (if a bit less accessible) destination that e.g. western Europe?

>>8021086
I have an idea. Lets send you and everybody that thinks like you to Mars and never hear from you again? :)

>>8021091

:D:D:D:D good idea senpai n_n

Personally I'm more interested in how they would simply recreate a magnetosphere to even retain an atmosphere there...

>>8021091

>>8021133

New here, tumblerites?

>>8021133
Gravity has more to do with maintaining an atmosphere than the magnetic field.

Venus has a shit magnetosphere but has a super dense atmosphere because it has near Earth gravity, so carbon dioxide doesn't reach escape velocity and thus it all stays bonded to the planet.

You'd have to have a dome city. Even assuming that terraforming is possible, you can't terraform Mars to be Earth-like because the gravity isn't strong enough for an atmosphere to stick. Nor does it have a strong enough magnetic field to protect said atmosphere.

>>8021016

I thought solar wind would trip you bare of any atmosphere if you had no magnetosphere. Can someone elaborate on that matter?

>>8021270
It does buts its very slow

>>8021034
it isn't just about heat. Mars has 1% the atmosphere mass of Earth.

>>8021287
Burn up a few icy asteroids and the atmosphere would get a lot thicker very fast

>>8021291
Mars doesn't have the gravity to keep as much of an atmosphere as Earth or Venus.

>>8021270
The answer is planetary geophysics are very complicated

>>8021280

How slow? Rough subjective estimation still appreciated to feed my curiosity.

>>8021310

If you were to share a bit of it in somewhat vulgarized language, I would be very happy to read it attentively.

>>8021307
It also has no magnetic field to stop radiation from eating away from the top of the atmosphere

>>8021356
It took about 3-4 billion years to go from an atmosphere that supported large bodies of liquid water to what they have now

>>8021140
But lighter gases like Oxygen and Nitrogen, aka the shit we actually need, HAS been stripped away by solar wind long ago.

>>8021475
Nitrogen is just a non-poisonous filler to bring the pressure up, we dont need it per se

>>8021016
Live underground, have machine like in Star Trek that creates things out of nothing.

Well actually the Trek replicators do need some base matter to make something. Though they never say what that matter is. It could just be a giant block of carbon, or pulled from the ship septic tank, or maybe a hunk of rock they pulled in from space...

>>8021016
Bash the hell out of it with as many asteroids as possible, preferably ice asteroids and comets. Then wait a long long long long time.

There really is no point to being on Mars beyond science and mining.

Surplus population can be stored in Oneil cylinders in Lagrange point orbits with in the Earth Sphere.

Certianly not terraforming.

Really terraforming is something that people shouldn't even consider. I mean, if you want to have enclosed communities on Mars that have their own inefficeient, industries spewing out tons of green house gases that is just fine; but what you need to realize and make peace with is the fact that you (and your great-great-great-great-great-grand children) will never live to see the results of terraforming Mars, and even if it could be done, it wouldn't be stable.

If you want to talk seriously about colonizing Mars, look into subterranean cities, multiple interconnected modules on the surface, domed over lavatubes, geofronts and the like.

>>8021269

>>8024465
>It's impossible and always will be.

You dont know that. But no its not a realistic possibility for anytime in the predictable future

>>8024470
Yes I do.

>>8021171
Mars' gravity is high enough to not be a problem for terraforming purposes. Its magnetosphere is only a problem in the insanely long term because while a magnetosphere indeed wards off solar wind, it billions of thousands or millions of years for said blowoff to have a noticeable effect.

The only reason Mars has a thin atmosphere today is because its gasses have been gradually blown off over the course of billions of years and nothing has been replacing what was getting blown away.

Assuming a future where martian terraforming has been successfully achieved, a large industrial civilization's exhaust would probably replace what was lost without too much trouble.

>>8024521

I think we should rather be concerned about how we can protect ourselves from the radiation.
Is an atmosphere that's probably thinner than earth's enough? What can we do to protect ourselves from solar winds?

>>8024643
Domed colonies will need sufficient shielding built into them. Hundreds of years down the line, the atmosphere will have become thick enough to shield the brunt of it, especially if the targeted goal atmospheric pressure is that of Earth, because in order for that to happen the martian atmosphere would need to be much thicker than Earth's.

To some extent. People tend to get depressed without sunlight, and I doubt that a crew that had just been in a tin can for 3-6 months is going to be keen on living exclusively in caves afterwards. Subterranean colonies with glass-domed top floors could work though.

>Is there anything at all in this?
That's long been thought of as part of the terraforming process, taking place alongside domed/underground colonization. Colony scientists equipped with proper equipment could speed up the process dramatically by being able to test and iterate their modified organisms in a real martian environment.

It's funny how you colonize Mars and Venus exactly oppositely.
For Mars you need to start with underground colonies, for Venus with floating colonies.
For Mars you need to increase atmopsheric pressure for Venus decrease
You need to heat up Mars and cool down Venus

Whichever direction we finally decide to take, we've really got to get past this "but colonization is hard" shit. Yes, it's ridiculously hard. This fact has been established since before even the moon landings. We've long known that space and the non-Earth bodies in it are extremely unfriendly to Earth beings.

There's no point in reiterating it though; not only because it's been common knowledge for decades now, but also because *it's a shit reason to not try colonizing*. Humanity has been making leaps because crazy fuckers periodically do shit that the rest of us consider crazy. If we stop trying crazy shit, we stop progression. It's as simple as that and getting hung up on, "but it's hard" is defeatism at its worst. If we continue the current inchworm-like approach we'll all have blown each other up before any notable progress is made.

The atmosphere on Venus is being stripped away, bu the solar wind
Venus has a comet-like tail, from this stripping
Earth regularly passes through part of this tail

>>8021027
Mars has .01% the atmosphere of Earth at it's equivalent "sea level", so no atmosphere to convert
To create these power stations ans massive solar sheets is beyond mankind's current and foreseeable future

>>8024521

Gravity is a problem on Mars, for humans
Mars has almost the same land surface area as Earth
But, it has only half the diameter
15% of Earth’s Volume
11% of Earth's Mass
Mars gravity is 62% lower than Earth's Gravity

>>8025459
Atmosphere and temperature are, along with no magnetosphere, big problems
Nearly 900 degree's Fahrenheit at the surface
93 Earth atmosphere's at the surface
Surface atmosphere so thick it would be like walking 100 feet under water on Earth

>>8026172
Nobody will know for sure until experimentation is underway, but I think it's a fairly good bet that human physiology would deal with partial gravity a lot better than it does zero gravity. 38% of Earth's gravity is a lot more than nothing.

Negative effects can probably mostly be counteracted by rigorous exercise and/or weightsuits. I also believe that martian humans, over the course of several generations, would become physically adapted to the lower gravity.

>What's the best way to colonize Mars?
First you double the gravity of the planet. Not sure how unless you add vast amounts of Uranium to the core, see below.

Then you restart the planetary dynamo to recreate the martian magnetic field. I am not sure how but vast amounts of Uranium in the core is expected to relate to this by basically being a self moderating liquid huge reactor.

Next you dump hideous amounts of cometary mass onto the surface to get some bodies of water going and something resembling an atmosphere. Perhaps you can take one of the Jovian moons or Ceres to do this. This adding of mass will also improve gravity.

At this point you have a lot of water and CO2 so heat is building up but you need to get some oxygen in there. You need to get some heavy duty photosynthesis going, something that works in low light and cool climate.

Next you need to upgrade your moons. Deimos and Phobos, cool as they might be, simply do not cut the mustard. Our moon kneads the crust to get the carboniferous cycle going and you need that on Mars too. Perhaps the remaining hulk of the Jovian Moon could do. If not, get another moon. Jupiter will not mind. I think.

Then you have the problem with heat, as in not enough of it. Even if you up the atmospheric pressure beyond 1 atm. and fill the atmosphere with huge amounts of green house gases you need more oomph. Here at Magrathea planetary services we propose 2 options: either place a whopper of a mirror at the nightside Lagrangian position to add heat and also dispose of the night. Alternatively we can tow Mars into L4 or L5 relatively to Earth and secure a balmy climate.

The problem with students is that they think that what works on paper = what works in real life

These ideas are comical, sure they make sense in theory but it's utterly infeasible.

>>8021016
There was an interesting documentary about terraforming mars on CuriosityStream. Basically about how we do have the technology to in theory terraform mars over the next 100 years or so, given enough resources.

The basic idea was to use some gas the name of which I don't remember, which is some 10 000 times more effective than CO2. It could be manufactured from the materials easily available on mars, so it's just about putting up a factory there to do it. It would take a couple of decades to raise the temperature just enough to melt the dry ice on the polar caps, further boosting the thickening and warming of the atmosphere, which in turn would enable the release of other gasses, eventually melting the water all over the surface.

They'd thought of the suitable plants and microbes from earth that are capable of enduring under extremely different pressure, temperature, lack of oxygen and irradiated conditions too.

It's a good service, I recommend it for any scifags who are interested.

>>8027136
SF6 and C3F8 would be pretty gud.

Also terraforming mars gets lot easier when you have self replicating robots to help do the hard work. Mars has all the resources needed to manufacture robots and power them up. Uranium and solar for energy.

Why send couple primates in a can when you can send robots first to build homes for basic infrastructure? Nasa could have done the robot factory shit back in the 80's if they'd had the money.

They don't provide much radiation shielding.
If you want Martian cities they should probably be underground.

It makes more sense just to fix the problem and depose the people running earth...

At 50 km, using the buoyancy properties of the Venusian atmosphere along with the idea behind the bilayer, where air pressure is about 1 atm and temperatures range along pic related.

Most plastics wont be affected by the sulfuric-acid haze, subsequently relatively easily circumvented until it can be removed from the atmosphere.

>>8027448
I suggest it for the colonization of Venus. Earth air is buoyant in its atmosphere. Lift increases cubicly along with volume,so the net weight of each node can be engineered to be zero.

The next problem is the materials needed. Sending it up from earth would be impractical. Asteroid mining comes as the default answer as the surface of Venus would be a bitch for mining.

So, step one: select asteroids with best proximity and mineral characteristics for corrosion resistant alloys or best alternatives.
step two: draw in a few asteroids to orbit Venus.

.. extract minerals in orbit, construct in orbit, lower earth air filled pieces with parachutes until they float, construct.

Of course you could redefine the problem and instead go for a re-engineered human species that is able to live on a bone dry planet with hardly any oxygen and at a pressure that is pretty close to vacuum. Even such a homo futuris would be hard to imagine how to do.

But if it isn't the magnetosphere, or gravity preventing the atmosphere to be stripped away, what's the reason then that the atmosphere on Earth isn't being stripped away?

>>8027783
It is the magneto sphere and by extension the fact the Earth is geologically active.

Why can't we create an artificial magnetosphere?

Basically we build on mars a nuclear powered city. The base gradually introduces plant life and oxygen or whatever sort of atmospheric gasses that are conducive to human life.

Also, for it to be a true colony we would need to kill all of the mars Indians and steal their land and women.

>>8027800
Probably not. A magnetosphere is a magnetosphere, accept no substitute.

You might however generate an artificial magnetic field to set up this magnetosphere, by, say, placing a gigantic superconducting magnet along the rotational axis squarely through the centre of the planet.

This may sound hard but so are all the other proposals so far here.

>a ton of antimatter
Detonate it slowly under the poles. CO2 and water vapor all around.

You know what's an actual issue? How will Mars economy work. Imagine you have a cluster of cities, with total population of 1 million. Asides from making food, what the fuck will they do? Recreating industry from scratch is ridiculously expensive and time consuming and we take so much for granted. Want steel tools? You need steel mill, with tools made from steel, coal mined with steel machines, steel all around. Not to mention iron ore and coal. Want to transport any of that? Good luck moving hundreds of thousands of tons just for basic industry. Want to recreate it on Mars? Good luck going literally middle ages blacksmithing inside a (likely) plastic city.

I mean, shit, from zero to microprocessor manufacturing (or whatever will be modern in 50 years) would take half a fucking century. Decades to make a self sustaining society that doesn't have to depend on handouts from earth just to stay alive. That's the biggest issue with Mars colonisation. Only exportable thing they have is scientific papers on Mars.

Japan, starting out from a bombed out country required less time back then. Why would it take longer time with modern tech?

Only the Greeks have succeeded spending more time using modern tech than ancient tech. Building Parthenon took 11 years, 2500 years ago. And they have spent the entire post war era rebuilding it, using kinda modern stuff. Unless you ship Greeks to Mars I cannot see this being a problem.

Also Japan again showed that you need little native resources to succeed.

Annihilate it, whatever. Small amounts at the time, hundred meter deep. Seriously though, I suggest something involving a metric fucking TON of antimatter and you nitpick about the correct term for releasing energy and launching shit into space.

>>from zero to microprocessor manufacturing
>Japan, starting out from a bombed out country required less time back then. Why would it take longer time with modern tech?
>Only the Greeks have succeeded spending more time using modern tech than ancient tech. Building Parthenon took 11 years, 2500 years ago. And they have spent the entire post war era rebuilding it, using kinda modern stuff. Unless you ship Greeks to Mars I cannot see this being a problem.
>Also Japan again showed that you need little native resources to succeed.
It's like you haven't even read what I wrote. Japan had industry, however shitty, and transporting shit to it didn't cost on the order of $1k/kg. You can't just stick hundreds of factories into a rocket, can you now.

>>Recreating industry from scratch is ridiculously expensive and time consuming
>thats really not true at all and you can just jump to the end point of having a smallish mostly autonomous factory
Producing what from what? Built from what? Repaired with what? You'd need to ship all that from earth in the first place,which brings us to my initial argument, that it's fucking expensive and time consuming. It's not like you can overnight a part from Earth.
>Most everything else can be 3d printed
Now that's just bullshit.
>And you don't particularly need steel for anything, even then you will likely see most of these basic industries going on in space.
US uses 100 million tonnes of steel a year. That's a lot for something you don't need for anything.

>And that requires energy, and quite a lot of it too.

I don't think anyone is delusional enough to think terraforming Mars doesn't require incredible amounts of energy.
We need to discover nuclear fusion as a clean and cheap energy source before we can terraform Mars

Visiting other planets for the foreseeable future is just a nice idea. It's never going to happen until governments or big businesses see a motivation to start throwing money at it, like the discovery of some kind of huge deposit of some sort of super valuable material they'd want to harvest. Colonization isn't even in the picture unless someone invents a moderately cheap method of creating a really large life sustaining environment.

All it will take is for the Chinese to express a real interest in colonizing the moon and america will be there tomorrow.
We wont let some gook motherfuckers get ahead of us in space.
Geopolitical reasons are what drive human spaceflight, it has 1% to do with scientific exploration.

>wahhh we won't go to space b-because evil corporations and goverments won't let us

How do you think America was colonized?
If want to build a ship, don't gather workers and make them collect wood, make them long for the vast distance beyond the sea

>We need to discover nuclear fusion as a clean and cheap energy source before we can terraform Mars
Nuclear fusion is not enough, you need to put a lot of other factors right and these do not rely on fusion, unless you have some surprises in for us.

You can make them all right with infinite energy
