Terraforming Mars would be irrelevant anyway when we discover the protomolecule.

We should do Venus before Mars. We could more easily Terraform Venus than Mars. Venus has a thick atmosphere with CO2 and Water Vapor, 90% of Earth gravity and is already habitable at an altitude of 50 Kilometers. We just need to reduce the CO2 so that the pressure and temperatures decrease and do something about the sulfuric acid. 1:28 Venus 3:09 Venus

I wonder how many flat earthers will be in the comments trying to say the moon and Mars are just lights in the firmament.

As always - interesting content 👌 Thank you Koranos! 💜

Turns out we we're the aliens we were searching for all along.

Great video. Love the beautiful graphics and the soothing background music. Much appreciated.

some say that an atomsphere created would last long enough in human years vs planet, but wouldn't nuke radiation last long enough too

The lack of a magnetic field means all of the hard work you put into developing an atmosphere is for nothing. Like another user said, better to just hollow out the planet and live underground.

Never understand why we don't ever see the idea of directing comet's towards planets for things like gas and ice.you have a whole planet to let them crash into and we are getting to a point we can almost land on asteroids. Seems just as feasible to do that with not so distant tech as it would to build a 100km mirror to divert the sun's rays to the poles. Again as many have pointed out a lack of magnetic field is an issue. But theoretically you can top up lost GHG with more comets.

Terraforming Mars? That’s sound interesting. Mind-blowing video. Join the journey to a new world!

Good stuff keep up the great work

Nice video! love your work!

Amazingly Nice 🚀

Yeah... I don't think that'll ever happen. Instead, I'd suggest hollowing out Mars' mountains and building gigantic, layered cave societies within them. This would completely circumvent the need for protection, as the outside of the mountain would shield from radiation, and you could just fill the cave system with oxygen so you don't need to wear suits.

What if you add a giant Magnifying glass on Mars? aimed at Mars equator.

There is one other issue that isn't mentioned as often - Mars lacks any suitable buffer gas (or compounds thereof). In Earth's atmosphere, that role is filled by nitrogen. While CO2 is sufficiently nonreactive to be useful in that role from purely chemical standpoint, "air" consisting of 21% oxygen (same as on Earth) and 78% CO2 at 1 atm pressure would very quickly lead to CO2 poisoning - in other words, it wouldn't be breathable. This also is resolvable, however, it would be quite daunting to perform. The atmosphere of Venus contains, if my math is right, roughly three times as much nitrogen as Earth's does (by mass - Venus has WAY much more atmosphere than Earth does, so fraction of nitrogen in Venus' atmosphere is actually quite small). I suspect there are other options for a buffer gas (I suspect argon could hypotheticaly be used? It is sufficiently inert, we are used to breathing it, as it is the third most common gas in Earth's atmosphere, but I am not certain if it wouldn't also function as an asphyxant if it comprised 78% of air at 1 atm pressure). There would be another restriction on what the buffer gas could be - if it would be helium (plenty of that in the solar system, although all of it in deep gravity wells), it would likely escape Mars eventually even with the magnetic field issue fixed. Either way, terraforming Mars won't likely be possible to result in a surface breathable air without massive import of external material. (just to note, while a 99% O2 and 1% CO2 atmosphere would probably aleviate the CO2 poisoning issue, it would be unpleasant to breathe, not to mention, I am not certain if such atmosphere at 1 atm pressure would be able to retain enough heat, and then there's the elephant in the room - near pure oxygen atmosphere at 1 atm pressure causes a LOT of every day materials to self-combust).

Welcome to the Martian Fyre Festival, you'll love the habitats and the cheese sandwiches

Ganamede is the only moon in the solar system with a global magnetic field. The magnetic field on Saturns moon Titan comes from Saturn itself.

0.6℅ atmospheric pressure. It's a dead end.

Why not instead people on mars works on a mega project that is basically a tunnel that wraps around the planet and connects to both sides? You would technically make the planet habitable before terraforming it and you can build from this Straight tunnel.

If we could terraform another planet we could also fix our planet

We should Terraform both Mars and Venus, Sol system with 3 habitable worlds would be cosy.

Because no one said it so far. The video looks great and i lobe this voice. Good job ❤

What if we terraformed Uranus?

If we can terraform a planet, Venus would be a better choice, due to the size and ability to hold onto the atmosphere. If you manage to make a breathable atmosphere on Mars, it will be gone in as little as 1,000 years. In order to retain the atmosphere you would have to block solar winds, and in doing so would reduce it's day time temperatures, making it even colder in the long run. In order to gain mass on Mars, so it can retain an atmosphere, we needs to take all the asteroids in the asteroid belt, including Ceres, and all the asteroids in front of and behind Saturn, and maybe even Jupiter, and make them crash into Mars, which will increase the internal pressures, and increase it's temperatures as the existing core reheats and then begins to slip as it spins at a variable speed much like Earth's (it could effectively restart the dynamo as a result). Crashing meteors into Mars really is the best course of action in order to make Mars livable, with each impact, it delivers minerals that get super heated and thusly increase the pressures of the atmosphere, at the same time as increasing Mars' mass to better hold onto that atmosphere. Impact of Ceres on Mars would in theory add a large amount of water vapor, as Ceres is reported to be an Icey Dwarf planet. Getting it to move would require setting up dual rockets at the poles, that stick out the sides, like the Naucells of the Starship Enterprise, but instead of a ship, it's the planet. And yes, it will require larger rockets than anything we have built currently (making it not feasible at this time). The Dart mission shows that we can effect asteroid trajectories, but can we do it without the loss of so much material?

We might be able to do this quicker than most expect since we are at the cusp of achieving agi or even asi ,it will accelerate our technology rapidly and with the increasing number of humanoid robots building such megastructures will be much quicker , we maybe able to achieve fusion in the near future enabling us to create huge amounts of heat energy to melt those ice caps , with advancements in quantum computing, managing such mega projects will be a breeze , material science will lead to new kinds of alloys and materials with some chance of discovering properties which might shift whole paradigm of whats possible like room temperature super conductors , carbon nano tubes etc

Ultimately, even with Terraforming, Mars will return to a barren wasteland because it doesn't have a spinning metallic core to generate a magnetic shield that keeps the atmosphere from ONCE AGAIN being stripped off from the sun. That magnetic shield is what REALLY prevents Terraforming and what really separates Earth from Mars.

Wow I had no idea that Mars had similar Seasons to Earth and was a tilt as well

Unless your able to say drag a mass like titan or Mimas into Mars' orbit, you won't get the sort of ecology that's earth-like.

Copying Kurzgesagt thumbnails down to the font 💀

Make one about the history of the magnetic field on earth and the influence of star link on erath magnetic fields!!!

Which software do you use making this video please learn me

wouldnt we need to inject molten metals into the core of the planet to get its magnetic shield up and going like earth has

Ooh your voice I'm addicted ❤

Kurzgesagt takes payoff money from billgates. This channel is the new kurzgesagt

New Kurzge- oh... cool!

Gotta start spinning mars faster to melt the core to generate a new magnetosphere which would protect an atmosphere from ilthe ionic particles being flung by the sun.

Better of knocking Mercury off it’s orbit in a calculated manner to send it at a collision course with Mars much the same as our moon was created but the habitable planet will be what’s left of Mercury as now a moon of Mars.

Even if (a big "if") we did everything else necessary to make Mars habitable one elephant in the room that we cannot get past is that the gravity is too low. Its about 38 percent Earth meaning a person who weighs 100 pounds on Earth would weigh 38 pounds on Mars. Prolonged gravity deprivation is terrible for the human body that has evolved for Earth gravity and lower gravity does not hold an atmosphere as well.

I seen this before

Nice video. Reminds me of In a Nutshell channel. :)

Space lasers!

There is an enormous gap in earth’s history in which nothing really happens. Talk at least several billion years. I think this is the time it took for all the microbes to assemble and by chance make plant life, which in turn became the soil (decomposition) after millions and millions of years. Terra forming Mars to look like earth would be a huge feat

The title makes absolutely no sense. It should've been something like "Why we can't terraform Mars" or "Is it possible to terraform Mars?"

The solar wind constantly stripes away the Mars atmosphere. Whatever terraforming efforts on Mars will eventually get undone by the solar wind.

Its a very intriguing concept but lets face it maybe our grand-grand-grand... children will see this happen...

Humans wrecked at least one planet. Why wreck another?

great❤

Why don't we first Terraform our earth back to what it was before we started pumping Carbon into the atmosphere?

Venus is more habitable than mars (at 50km up)

Give me the soundtrack pls

5:33 Why would it be ethically challenging, when mars has 0 population and no organic life.

It's easier to genetically engineer humans for living on Mars.

U r better than the channel kurzgestan i would say 😅

Geoengineering then Solar Engineering

It would be relativly easy just take a lot of money we will be on mars in 10 years

Seems like a possibility by 2100

How about restoring the earth first?

Video idea what if we created ftl technology

My understanding is that it legitimately may be easier to terraform Venus. Would you be able to do a video on that?

Why not just wait it out🤷🏾‍♂️..imean time and chance made our planet habitable..so why cant it happen on mars?

with no magnetic core to protect it from the sun's solar radiation ....... terraforming is futile to put it nicely .

Mars atmosphere is 0.6% the size of Earths😮

Its too small to hold down a thick atmosphere for very long, so the mass of the planet would have to be increased to the size of earth. Just put domes all over the surface

It would still be cheaper than housingvin new york

why not make earth more habitable? why not turn deserts into forests? clean up oceans ?

If we use trillions to terraform mars we are dumber then i thought. All that money could go to saving the planet we live on today

So, when we terraform Mars, can we rename it 'Muskmelon' in honor of our favorite space pioneer? Elon's face on the new currency, anyone?

Barsoom

Koranos always have this depressing 'all-is-lost' music.

The cockroaches and the secrets of the Rahab can stay on Mars (watch Terra Formars, it's better than the reviews)

The title: What if we terraform mars? The video: it's not viable So why make the video? 🤔

Lol there are more comments than views. Chase that early comment upvote

This channel is very similar to another science channel😂

We

one simple reason all of that won't happens : 3.71 m/s enjoy osteoporosis.

Terraforming a whole planet, to suit current human biological limits, is thinking backwards. It's easier to adjust ourselves to the planet. We will very soon have conscious beings (AI and cyborgs) that don't need Mars to be earth-like to live in it, and they are the ones that will inhabit it first. Granted this isn't incompatible with a long-term terraforming goal, for the sake of having a new unique biosphere in our solar system, with its own diversity. But the idea that we need to terraform planets to accommodate to current homo sapiens, is unrealistic and short-sighted reasoning. As we spread across the stars, it will mainly be as uploaded brains that can enter any kind of of android body, suited to explore the conditions of those planets. Brain uploads and AI's are less than a century away, while terraforming is 2-3 centuries away. So the order of events will be as such.

who cares, I don't live that long enough

Kurzeverse

There's optimism, and there's this. This is so far beyond our capabilities and understandings even ten thousand years from now. It requires a perfect civilization and we will never become one. Throwing this concept around like it's child play and getting average people to obsess over it is just wrong.

What if we copied Kurzgesagt?

venus is better candidate for terraformin. its very similar to earth

SECOND

We'd strip the planet of all it's resources so that an equivalent to Elon Musk could be a quadrillionare.

Hi, thanks for the awesome video upload. I personally believe/think we should invent chemicals to change the mars thin atmosphere from CO2 to mostly O2 ( oxygen ) by emitting gases into it's atmosphere from space. Also; in the near future we should consider/evaluate to implement artificial magnetic field to planet Mars to prevent radiation from sun or space from reaching Mars. 🚀🌺

We should redirect icey astroids to Mars and replenish the resources
