My idea for the Venus atmosphere problem also fixes a Mars issue. We can place orbital mini factories in orbit of Venus that would drop long vacuum hoses down. They would suck up the atmosphere, chemically separate it, freeze the CO2, expel the sulphur compounds into space or possibly use them for something else, and store the dry ice in discrete units loaded into interplanetary transports. With hundreds of relatively small devices, tons of CO2 and sulphur compounds could be removed annually, with the CO2 packaged for delivery to Mars to help bulk up its atmosphere (along with other remedial methods).
the whole asteroid bombarding thing is probably not worth the trouble, since it would require hundreds of asteroids, with ten or more kilometers, to make a diffrent. The impacts on Venus would bring even more material into its athmosphere and at the end there would be no gain from it. I think there are better purposes for them..... But the idea of "stealing" hydrogen from Jupiter sounds rly interesting. Love that idea :D
Gravity is close to earth, rocky planet, upper atmosphere is moderate temperature, and it's much closer than Mars. Extremophiles can thrive in the upper atmosphere and be distributed throughout the planet, converting sulfuric acid when encountered. Microbes would survive and breed in the upper atmosphere and work their way to the rest of the planet.
Hey Anton love you videos but you didn't mention that Venus' several Kilometers up has a temperature of about 30 degrees Celsius. Why couldn't bacteria survive there and do its job of changing Venus' atmosphere?
Indeed, a balloon filled with earth-atmosphere would float above most of the acid clouds on Venus in a part of the atmosphere that has very comparable composition to earth's atmosphere. Balloons made of a transparant material could hold cyano-bacteria. Since the atmosphere pressure is comparable to earth, you can have small holes open and shut to allow additional CO2 to enter and O2 to exit. Then we need to bioengineer bacteria to "breath" Sulfuric Acid and produce water, perhaps by using starch or sugar produced by the cyanobacteria... Anyway, I am sure some smart guy somewhere already mapped this all out and the problem is just that it costs a lot of money and time... ;-)

Its not 70 Degree up there, its 70 Kelvin. What u where talking about is a layer of chilled sulphuric acid and diffrent to water, the acid want freeze but stay reactive. Venus is basicly a lake of acid, floating on a bed of hot carbondioxide. Above the lake, quick comes nothing. And its incredible expensive to get there. No straight transfer exist, because venus is way to fast.
@@Kholdaimon If you could engineer an airborne organism that can photosynthesis you'd have something viable with plenty of C02 and sunlight. But then it would also need plenty of water.
We have a variety of bacteria on Earth that can metabolize sulfur. Sulfolobus for example. Purple and green sulfur bacteria groups may also be helpful. Some of these might be a good starting point to modify for terraforming purposes.
In 1000 years, Venus could be a vacation-world where It's day on one side and night on the other, and you can have party-ships ferrying people back and forth over the terminator. Wild parties on the islands.
The best way to use those bacterium to convert the CO2 into O2 is to build platforms in the upper atmosphere that float like blimps above the acidic layers of the atmosphere (You could also use tree farms as well). As the CO2 levels drop, so will temperatures and you would be able to lower the platforms to lower and lower altitudes until you reach the surface. As this is happening, you introduce chemicals that will clean the acid from the atmosphere making the planet more habitable by the time you reach the surface, or at least the higher plateaus.
I remember watching a Manga movie called Venus Wars. (1989) There was this huge Ice asteroid colliding with the planet, essentially making it liveable for humans. But bacteria seems very much more likely to do. I also suggest Venus to be terraformed as well.
Venus is only super-hot at low altitudes. What seems to be needed is a really high mountain built by an AI controlled bulldozer, or perhaps some sort of high-altitude flying platform on which to grow your plants. The high-altitude area need not be extremely large - depending on your patience while you wait for your bacteria to do their job.
In one of your old terraforming Venus videos from a few years ago you bombarded the planet with organic material from the launch tools. Was that feature removed from later versions of the sim? If it's still there, how do you do that?
A terraformed Mars would have enough gravity to hang on to oxygen and nitrogen but not enough to keep hold of water vapour which would escape into space so oceans on Mars couldn't be sustained.
Uranus is too big, and there’s too much gas. Also, I’m not sure anyone would want to go to Uranus, and worse still it might be difficult to leave Uranus due to its mass. On the plus side, due to size I’m sure billions of people can see Uranus, and even fit in it, if you can design a rocket to survive entry.
Is it possible to block all light (eclipse the sun) by placing a body in the Venus' L1 Lagrange point? I know there is a simulation for the Trojan asteroids but could you show us Venus- L1 position and if it would cool the planet and thus it's atmosphere too?
Could work, we just need something about the size of Venus placed within her orbit. Another planet maybe? Hmm, I know of one candidate. Hey, are you using this Earth, or...?
A group of micron-thin mirrors to relfect light away from venus is a seriously considered way to cool venus. The CO2 would slowly condense and freeze, then it could be insulated and shipped away using mass drivers.
Couple things I would recommend, solar shielding the planet which is less work than trying to pull thousands of asteroids from the belt into the planet, then growing the enzyme en mass on the surface to break down the so2. The solar shield would act as a solar power source to run a planetary electrolysis system. No need to get rid of anything, just reform the materials.
Great vid. Always wondered why Mars when you have to add so much to make it habitable when you have Venus that needs stuff taken away. Any person can tell you its easier to remove stuff than it is to put stuff back. Actually.... if you bombarded Venus with hydrogen and a catalyst it would make hydrocarbons ( fuel ) for rocket missions back and forth to earth or beyond. The bacteria theme. Why not use balloons with a coating like a scrubby sponge for the bacteria to live in in the cooler upper Venus atmosphere. As the bacterial colony grows the balloon slowly sinks giving the bacteria time to adapt to the nastier environment until it reaches the surface and the adapted bacteria could then quickly colonize the land and reduce the Venus atmosphere to habitable conditions. Thought..... would the first Venus explorers want to trudge through the thick layer of bacterial slime after the atmospheric terraforming.... ewww snot planet need a tissue?
Getting the temperature down seems like the biggest priority.If we just upped the albedo by 50% it would start to cool on it's own. Make the bacteria white, and have them produce a fine mist to help reflect sunlight.
People often forget or don't know that Venus' oceans evaporated long ago. Its one of the main reasons why Venus has a runaway greenhouse effect. As the oceans evaporated there was nothing to absorb the CO2 that was being naturally released. Water vapor aka H2O is a very effective greenhouse gas, something that is often overlooked. Anyway, the real point that I wanted to make was that adding hydrogen and oxygen to Venus isn't enough to do much of anything. The reason is Venus' weak magnetic field allows solar wind to carry away lighter particles such as hydrogen, helium, and oxygen. It's why despite having the whole planets ocean in the atmosphere there is so little hydrogen and oxygen. If we had a way to add more it would literally get blown away. We would need to address the problem of the magnetic field first.
We could use the same approach that NASA has envisioned for Mars. The plan is rather simple, just set up an artificial magnetosphere in the L1 spot between Venus and the sun. This will deflect the solar wind and protect Venus atmosphere. This artificial magnetosphere could be be projected from a captured asteroid and this could also be used as the raw material for a sun shade that would help lower the temperature on Venus. One problem however is that this would in essence become a huge solar sail and risk blowing away..
would there be a way to just launch rockets full of hydrogen and a dentonation system. then in those ares we can also release bacteria because we made a zone with far less acidity. just like the run away green house effect there has to be a method of to make a runaway nutrilizing effect, right?
It's completely wrong to say Mars cannot be terraformed because of its gravity... yes i heard you say PERMANENTLY, but obvious we do not need it to be habitable forever, we could just replenish the atmosphere over time, as long as it supports some millions of years of stable atmosphere, which IS the case of Mars, i don't see the point of only wanting a PERMANENTLY stable atmosphere, if you had all the problem of terraforming it, it would be a small issue to just maintain it over time. Probably even the Moon could be terraformed as long as you replenish the gases often enough, which will prob. be an easy task for our civilization thousands or millions of years in the future (when we would actually need to replenish it and stay replenishing it).
We could get lots of oxygen by breaking of the carbon dioxide in the atmosphere (e. g. by photosynthesis with heat resistant bacteria) That could also work if you would terraform Mars.
Sure. Plants are part of the food chain. So there would be food, and they make oxygen during the daylight hours. ... If you can eventually make them take hold on Venus, over time, the atmosphere will reach an equalibrium that will make it breathable for animals and humans too.
I think it's more about atmospheric pressure and magnetosphere in terms of holding onto oxygen than it is a bout gravity. Mars is perfectly terraformable. The biggest issues I see is the effect of low gravity on humans (bones, muscles) long term (a separate sub species of human will emerge) and the fact its regolith is toxic.
Well, I am quite sure that is not possible to create ANY bacteria that can hold up to temperatures over 400°C, since the proteins would just not hold up and they still need liquid water, but I guess you mean floating bacteria high up in the atmospere where it isn't as hot.
Best way to terraform Venus is to use mirrors to reduce the solar energy + change the chemistry within the atmosphere + find a way to accelerate the rotation of the planet.
I don't have any timeframe estimate for Terraforming Venus, however I am confident that we can start with technology that isn't much more advanced than what we already have. I have read how approximately 50km above the surface, the pressure and temperature are reasonable analogs of Earth's surface if you want to drift in a FLOTILLA OF AIRSHIPS(requiring sulphuric acid resistant membranes) joined together. Sulphuric acid (H2SO4) being soluble in water in a highly exothermic reaction could create the heat to power the conventional steam turbine electrical generation tech. With the capacity to power laboratories able to split H2SO4 into oxygen, hydrogen(fuel cells) and elemental sulphur. Drawing carbon dioxide into freezers that convert it into dry ice cubes, measuring 10m to a side, which can be dropped onto the mountain peaks and the heat that sublimes the dry ice into rivers flowing into the valleys (dense cold air sinks). Retaining some CO2 for the greenhouse airships.
Bringing hydrogen from Jupiter to Venus and turning the CO2 into water and graphite via a Bosch reaction in floating stations in the atmosphere sounds like the most practical/realistic way. It would probably be faster than bacteria. And I don't think impacting comets or asteroids on Venus would really change much about the atmosphere, since even the little amount of atmosphere that gets ejected will mostly just fall back to Venus. I wonder if we could build giant blimp-like gas storage spaceships that have a long pipe that can either suck off gases from Venus' atmosphere and bring them somewhere else, or collect hydrogen from Jupiter and bring it to Venus. We could also use electrolysis reactions to turn some of the created water into hydrogen and oxygen, so we already have oxygen in the atmosphere, and the hydrogen could be used to remove more of the CO2. This would also have the advantage of reducing the ocean area on the surface, since we would want to have less than 80 % covered so we have more land mass.
But couldn't you terraform Mars and have something generate enough gas, so that even a loss of atmosphere would equalize with the amount that's being created?
If you create a chain of robot ships that can travel in an eccentric orbit to fly between Venus to Mars that will skim each planet’s atmospheres one that scoops up and fills large tanks with the Venus atmosphere and along the way process into useful gasses for Mars. Also this technique could be used scooping hydrogen from Jupiter to both planets, with each run during processing filter gasses to create fuel for ion thruster powered by solar panels that can also be a type of solar sail.
Perhaps you could talk about the difference in cost between between custom rotating habitat and terraforming a planet. If its cheaper to build some kind of second planet like structure rather than fixing a huge planet, then that may better strategy to get off earth and explore/ colonize universe
Ya but it’s not super hot higher in the atmosphere is it? Could the bacteria stay or survive there? Couldn’t it work it’s way down from higher altitudes over time thinning out the co2?
Probably not an authoritative source, but a "book of the planets" I read at our small-town library as a child described using algae as an essential oxygen generator on Venus. Presumably after the extremophiles got done. I wonder if anybody is still writing about algae for Venus.
9:56 you need again Mars sized object with mostly Hydrogen smack to Venus to make it clear Atmosphere and it Axis Rotation Make it flip over again to faster rotate and spin same as earth
Can bacteria be made to float like a microscopic balloon in the upper atmosphere where the temperature is not to hot and not too cold? Then it can munch on the co2 below and eject oxygen as a waste product that floats up. The co2 atmosphere is slowly consumed and stored in the bodies of the bacteria once it dies and falls to the ground.
Could you build a massive solar shade at the Venus L1 (combined with an artificial magnetosphere) to reduce the temperature enough to allow the bacteria to survive and start converting the atmosphere?
Dropping asteroids of any sort on Venus sadly would only make it HOTTER ;) The solar shade ideas have merits, plus it could power various terraforming processes. There is still the lack of a magnetosphere to protect the atmosphere from the solar wind. One possibility would be to make the solar shade translucent to allow less light through(maybe a variable solar shade?). Developping hardy extremophile archaea to float in the cooler upper atmosphere of Venus to break down CO2 and SO2 might be tried as well. Another problem for which we lack the technology would be to stabilize Venus' crust...currently it has no plate tectonics so no CO2 recycling, SO2 recycling, or heat venting other than massive planet wide eruptions. And of course as was mentioned, no magnetosphere, unless a artificial one would be put in orbit of Venus(we do not know how to kick start Venus' outer liquid core to spin up again).
Another point to consider about these CO2 eating bacteriums: they'd have to be engineered to withstand a fairly wide range of temperature and C02 levels, but drop dead when CO2 gets close to Earth-like levels. Because if they were still alive they'd keep on eating and reproducing until the CO2 got too low, and Venus would begin to freeze! (Or at least the side facing away from the Sun would freeze, and the side facing the Sun would get too hot.) Imagine how hard it would be to sterilize the entire planet if the bacteria didn't go extinct when we wanted them to.
Another idea is to create all sizes of robotic insects that eat the comets,asteroids,etc untill their gone and bring it to where ever its needed this way we will use the most of the elements without it vaorizing or bouncing back to space
Its effect reflects 90% of sunlight and the planet heats up itself though. So if we cant remove that dangerous atmposhere we are probably pushing venus in mars / jupiters orbit.
Let's get one thing straight: not only can Mars hold onto an atmosphere for a long enough period, but it's also going to be the first to get colonized and terraformed bc it's the easiest to do. Basically this is what's gonna happen: humans are gonna colonize Mars mostly with the help of robots, they're gonna start terraforming it with GM organisms and they're also gonna create a system of replenishing the atmosphere that'll get constantly stripped away by the solar wind. The reality is that Mars is orders of magnitude easier to terraform than Venus and that's the main reason it's gonna be done first. Hell, even Mercury might be terraformed before Venus. Venus is also eventually gonna be done but it will take much longer and it will require more advanced tech.
Carl Sagan later recanted that bacteria wouldn't work because once the CO2 turned into graphite and fell to the surface the incredible heat would vaporize it again and it would combine to the oxygen rich atmosphere, and his plan changed the atmosphere pressure 65 bars from 90.
bacteria don’t need to be on the surface to start converting the atmosphere. microorganisms could float on air currents in a habitable zone of the atmosphere. As the CO2 level drops, the habitable zone would expand until it reaches the surface
We just need floating cities with a bubble over them. I’m sure if you had enough surface area you could float on the top of the co2 and live in the water layer.
We know how to reduce carbon dioxide on Earth. We just need the political will to make it happen. What concerns me about bacteria is, what if it removes too much carbon dioxide?
You could seed the atmosphere with bacteria and plants - like a type of plankton as the atmosphere is that dense. They would consume CO2 and possibly SO2 into more useful products.
Dear Anton : from my prespective (my opinion) the bigger problem is to get rid/transform sulfiric acid or sulfur dioxide to other non harmful but life genereting elements and next carbon dioxide (CO2) to carbon (C) and oxygen (O2).
Bombarding it with asteroids seems like the best option. Google project orion. we already have the technology to move even the biggest of asteroids if we wanted to
I have always thought there has to be a way to transform the atmosphere of Venus. Plants turn carbon dioxide into oxygen everyday. I would think reversing the greenhouse effect would be useful knowledge for our planet in the future.
Now that I have finished the video I have to disagree with you. We should never genetically modify living creatures. Plant life is one thing but bacteria is another entirely. The curiosity of mankind doing something like that while having the best of intentions is what is going to kill off our species. Mother Nature doesn’t like competition and adjusting her creation to fit our needs will be about her wrath. I was thinking we could chemically alter Venus. Quite a bit of Potassium superoxide could be sent there or perhaps even building a big Pressure Swing Adsorption machine and deliver it to Venus in sections. I am sure switching the main filter from nitrogen to CO2 wouldn’t be too difficult. I am sure it would take quite awhile for such a machine to filter Venus but by doing that and reducing the pressure and temperature by half would open up so many doors for additional ways to taraform.
The problem with mars is not the low gravity. It’s the fact that it doesn’t have a magnetic field. It currently has very little atmosphere because gravity is doing all the work and there is no protection from the sun blowing away most of it. If it had a magnetic field mars could have a thicker atmosphere. It would be thinner than earth as seal level but it would be akin to the atmosphere that earth has at on the peaks of some of the highest mountains. The magnetic field problem is what keeps Mars from ever being terraformed. If it did have a magnetic field and it can have a thicker atmosphere than it currently has humans can live there with minimal PPE. Maybe they’d have to use O2 bottles to stave off hypoxia but that would be it. Indoor spaces would be pressurised but the outside could be as lush as an alpine tundra biome could ever be.
can they let ice comets crash in to the planet? need a lot of them but could it be feasible ? question is answered at end video lol. are there plans for venus or is mars the only focus? it takes time to terraformation the planet
I think Venus is a better bet than mars, I mean, if we thinned the atmosphere or cleared the clouds I think the tempature could at the very least become doable, and at most habitable, and we wouldn’t even need to make the atmosphere thicker cause there’s enough pressure for water to exist in a liquid state, all we’d need to do is lower the temperature and add oxygen and nitrogen
More and more studies suggest that Mars had a more dense atmosphere and liquid water once. It is likely to be able to hold on to breathable atmosphere for a few million years (the whole human civ is what, 10000 years?). Especially if erosion is prevented. Yes, Mars is loosing most of it`s atmosphere to erosion due to lack of magnetic field rather then low gravity. Proposals to create artificial magnetic field with today`s technology exist. That said, I would prefer Venus for terraforming too. As for removal of atmosphere, I think there is no golden egg, combining different methods and introducing them in the right order seems to be the most feasible. Starting from the top, where conditions are less harsh, so equipment has to be less durable meaning cheaper. Since both N2 and O2 are lighter then CO2, an air filled habitat floating on the dense CO2 atmosphere is quite possible. If autonomous, could be filled with He2. Once surface pressure and temperature would drop to a more acceptable level for machinery, autonomous plants would start the removal of CO2 from the bottom as well. Alkali Earth elements can bond CO2 to create stable molecules (rocks basically). In the meantime floating bacteria can brake down CO2 as well. Finally, with the introduction of H2, CO2 amount could be reduced further, creating water, which could stay in a liquid state if temperatures are reduced far enough. Even with all CO2 removed we would still have a roughly 3 atm surface pressure N2 atmosphere. Some N2 would eventually dissolve into the new ocean, the rest could be turned into nitrates by surface plants. This all done still leaves a few questions. Would settling on surface possible due to intense volcanic activity? Would the planet be cold enough for human life? Even with greenhouse effect removed, Venus still gets more sunlight then Earth? How would the temperature fluctuate between day and night?
I wonder how much water is in the Venusian atmosphere? If we could point a few large comets at the planet, without risking a collision with the Earth, maybe we could start cooling the planet.
Thankfully someone is actually doing something with Venus. It's so underrated
It isn't, it will be engulfed by the sun earlier than earth.

It's completely wrong to say Mars cannot be terraformed because of its gravity... yes i heard you say PERMANENTLY, but obvious we do not need it to be habitable forever, we could just replenish the atmosphere over time, as long as it supports some millions of years of stable atmosphere, which IS the case of Mars, i don't see the point of only wanting a PERMANENTLY stable atmosphere, if you had all the problem of terraforming it, it would be a small issue to just maintain it over time.
Probably even the Moon could be terraformed as long as you replenish the gases often enough, which will prob. be an easy task for our civilization thousands or millions of years in the future (when we would actually need to replenish it and stay replenishing it).
We could get lots of oxygen by breaking of the carbon dioxide in the atmosphere (e. g. by photosynthesis with heat resistant bacteria)
That could also work if you would terraform Mars.
How about a video like this but more focused towards Titania?
What about plant life on mars ?? It is a really great idea
Sure. Plants are part of the food chain. So there would be food, and they make oxygen during the daylight hours. ... If you can eventually make them take hold on Venus, over time, the atmosphere will reach an equalibrium that will make it breathable for animals and humans too.
Venus was my favorite location in Destiny glad to see the best planet get some attention
I think it's more about atmospheric pressure and magnetosphere in terms of holding onto oxygen than it is a bout gravity. Mars is perfectly terraformable. The biggest issues I see is the effect of low gravity on humans (bones, muscles) long term (a separate sub species of human will emerge) and the fact its regolith is toxic.
Well, I am quite sure that is not possible to create ANY bacteria that can hold up to temperatures over 400°C, since the proteins would just not hold up and they still need liquid water, but I guess you mean floating bacteria high up in the atmospere where it isn't as hot.
Best way to terraform Venus is to use mirrors to reduce the solar energy + change the chemistry within the atmosphere + find a way to accelerate the rotation of the planet.
Simpsons did it!
I don't have any timeframe estimate for Terraforming Venus, however I am confident that we can start with technology that isn't much more advanced than what we already have.
I have read how approximately 50km above the surface, the pressure and temperature are reasonable analogs of Earth's surface if you want to drift in a FLOTILLA OF AIRSHIPS(requiring sulphuric acid resistant membranes) joined together.
Sulphuric acid (H2SO4) being soluble in water in a highly exothermic reaction could create the heat to power the conventional steam turbine electrical generation tech.
With the capacity to power laboratories able to split H2SO4 into oxygen, hydrogen(fuel cells) and elemental sulphur.
Drawing carbon dioxide into freezers that convert it into dry ice cubes, measuring 10m to a side, which can be dropped onto the mountain peaks and the heat that sublimes the dry ice into rivers flowing into the valleys (dense cold air sinks).
Retaining some CO2 for the greenhouse airships.
Bringing hydrogen from Jupiter to Venus and turning the CO2 into water and graphite via a Bosch reaction in floating stations in the atmosphere sounds like the most practical/realistic way. It would probably be faster than bacteria. And I don't think impacting comets or asteroids on Venus would really change much about the atmosphere, since even the little amount of atmosphere that gets ejected will mostly just fall back to Venus.
I wonder if we could build giant blimp-like gas storage spaceships that have a long pipe that can either suck off gases from Venus' atmosphere and bring them somewhere else, or collect hydrogen from Jupiter and bring it to Venus.
We could also use electrolysis reactions to turn some of the created water into hydrogen and oxygen, so we already have oxygen in the atmosphere, and the hydrogen could be used to remove more of the CO2. This would also have the advantage of reducing the ocean area on the surface, since we would want to have less than 80 % covered so we have more land mass.
But couldn't you terraform Mars and have something generate enough gas, so that even a loss of atmosphere would equalize with the amount that's being created?
Is Venus inside the Goldilocks zone?
Mars needs a magnetic field too
Need Giant Magnet Magnetic field ON South and North pole
If you create a chain of robot ships that can travel in an eccentric orbit to fly between Venus to Mars that will skim each planet’s atmospheres one that scoops up and fills large tanks with the Venus atmosphere and along the way process into useful gasses for Mars. Also this technique could be used scooping hydrogen from Jupiter to both planets, with each run during processing filter gasses to create fuel for ion thruster powered by solar panels that can also be a type of solar sail.
Perhaps you could talk about the difference in cost between between custom rotating habitat and terraforming a planet. If its cheaper to build some kind of second planet like structure rather than fixing a huge planet, then that may better strategy to get off earth and explore/ colonize universe
If I find a stargate portal buried in my backyard in Cameroon, Africa. Do local or world govts have the jurisdictions to come and seize it ?
what about a catalyst that creates an endothermic reaction that captures sulfuric acid and releases H2O?
Ya but it’s not super hot higher in the atmosphere is it? Could the bacteria stay or survive there? Couldn’t it work it’s way down from higher altitudes over time thinning out the co2?
Probably not an authoritative source, but a "book of the planets" I read at our small-town library as a child described using algae as an essential oxygen generator on Venus. Presumably after the extremophiles got done.
I wonder if anybody is still writing about algae for Venus.
Excelent vídeo as aways man, thanks!
How do u give another planet an atmosphere like venus
9:56 you need again Mars sized object with mostly Hydrogen smack to Venus to make it clear Atmosphere and it Axis Rotation
Make it flip over again to faster rotate and spin same as earth
Put a massive shade in front of Venus to reduce the temperature
Can you discuss crashing Ceres into Venus. It has is a water rich body.
What version is this?
Genetically modified bacteria is how you start a zombie apocalypse
Can bacteria be made to float like a microscopic balloon in the upper atmosphere where the temperature is not to hot and not too cold?
Then it can munch on the co2 below and eject oxygen as a waste product that floats up. The co2 atmosphere is slowly consumed and stored in the bodies of the bacteria once it dies and falls to the ground.
increase mass first with asteroid bombardment ... can it fix rotation and mass size and remove c02?
Could you build a massive solar shade at the Venus L1 (combined with an artificial magnetosphere) to reduce the temperature enough to allow the bacteria to survive and start converting the atmosphere?
Oh, should have watched part 2 before commenting...
Dropping asteroids of any sort on Venus sadly would only make it HOTTER ;)
The solar shade ideas have merits, plus it could power various terraforming processes. There is still the lack of a magnetosphere to protect the atmosphere from the solar wind. One possibility would be to make the solar shade translucent to allow less light through(maybe a variable solar shade?). Developping hardy extremophile archaea to float in the cooler upper atmosphere of Venus to break down CO2 and SO2 might be tried as well.
Another problem for which we lack the technology would be to stabilize Venus' crust...currently it has no plate tectonics so no CO2 recycling, SO2 recycling, or heat venting other than massive planet wide eruptions. And of course as was mentioned, no magnetosphere, unless a artificial one would be put in orbit of Venus(we do not know how to kick start Venus' outer liquid core to spin up again).
What about Aerial based Carbon Capture machines?
Another point to consider about these CO2 eating bacteriums: they'd have to be engineered to withstand a fairly wide range of temperature and C02 levels, but drop dead when CO2 gets close to Earth-like levels. Because if they were still alive they'd keep on eating and reproducing until the CO2 got too low, and Venus would begin to freeze! (Or at least the side facing away from the Sun would freeze, and the side facing the Sun would get too hot.) Imagine how hard it would be to sterilize the entire planet if the bacteria didn't go extinct when we wanted them to.
Wouldn't giving venus a moon, solve the problem. Venus needs faster rotation (to cool) , and the gravity of a moon to stir things up.
Mercury.
Another idea is to create all sizes of robotic insects that eat the comets,asteroids,etc untill their gone and bring it to where ever its needed this way we will use the most of the elements without it vaorizing or bouncing back to space
great video! when is part 2?
how bout this one,(fully or partially) block out the sun and let venus cool down a bit let bacteria loose or just shove off the now frozen co2 :D
i think its better if you use your thumb to block the sun, just be careful or it might get too cold around the earth, that would suck :3.
Increase its rotation
A set of thin mirrors is a seriously considered way to do it.
What about somekind of shield / umbrella strategically hoovering between Venus and the sun to block the sunshine and cool down the atmosphere ?
Its effect reflects 90% of sunlight
and the planet heats up itself though.
So if we cant remove that dangerous atmposhere we are probably pushing venus in mars / jupiters orbit.
Plus, there you will become very sick and also a lot of heat stays there
That is a seriously considered way to do it.
Let's get one thing straight: not only can Mars hold onto an atmosphere for a long enough period, but it's also going to be the first to get colonized and terraformed bc it's the easiest to do. Basically this is what's gonna happen: humans are gonna colonize Mars mostly with the help of robots, they're gonna start terraforming it with GM organisms and they're also gonna create a system of replenishing the atmosphere that'll get constantly stripped away by the solar wind. The reality is that Mars is orders of magnitude easier to terraform than Venus and that's the main reason it's gonna be done first. Hell, even Mercury might be terraformed before Venus. Venus is also eventually gonna be done but it will take much longer and it will require more advanced tech.
How much hydrogen do we need?
Loved it!
We terraform mars when the sun is too hot and we can add mass to mars with asteroids from the asteroid belt
Carl Sagan later recanted that bacteria wouldn't work because once the CO2 turned into graphite and fell to the surface the incredible heat would vaporize it again and it would combine to the oxygen rich atmosphere, and his plan changed the atmosphere pressure 65 bars from 90.
bacteria don’t need to be on the surface to start converting the atmosphere. microorganisms could float on air currents in a habitable zone of the atmosphere. As the CO2 level drops, the habitable zone would expand until it reaches the surface
Carbon nano sail in front of the sun..a small hole in the middle to create a camera obscura effect.
Mars actually does have enough gravity to hold an atmosphere. The Moon doesn't, but we could build worldhouses around it.
We just need floating cities with a bubble over them. I’m sure if you had enough surface area you could float on the top of the co2 and live in the water layer.
hey, with getting hydrogen from jupiter, we could just use exermely powerful magnetic feilds to basicly create a laser of hydrogeon from the sun
"... even though I'm kind of showing it to you right now" , hahaha
great vid
We know how to reduce carbon dioxide on Earth. We just need the political will to make it happen. What concerns me about bacteria is, what if it removes too much carbon dioxide?
for humanity is easy create lots of carbon dioxide, so that is not a problem
Snowball Earth was not a very nice place to live.
You could seed the atmosphere with bacteria and plants - like a type of plankton as the atmosphere is that dense. They would consume CO2 and possibly SO2 into more useful products.
Dear Anton : from my prespective (my opinion) the bigger problem is to get rid/transform sulfiric acid or sulfur dioxide to other non harmful but life genereting elements and next carbon dioxide (CO2) to carbon (C) and oxygen (O2).
We can Terraform Mars! In the Future we have the technology to increase pessure!
Why dot develop bacteria that is floating in the atmosphere converting the CO2 then once the temperature drops we could work on the surface.
Bombarding it with asteroids seems like the best option. Google project orion. we already have the technology to move even the biggest of asteroids if we wanted to
I have always thought there has to be a way to transform the atmosphere of Venus. Plants turn carbon dioxide into oxygen everyday. I would think reversing the greenhouse effect would be useful knowledge for our planet in the future.
Now that I have finished the video I have to disagree with you. We should never genetically modify living creatures. Plant life is one thing but bacteria is another entirely. The curiosity of mankind doing something like that while having the best of intentions is what is going to kill off our species. Mother Nature doesn’t like competition and adjusting her creation to fit our needs will be about her wrath.
I was thinking we could chemically alter Venus. Quite a bit of Potassium superoxide could be sent there or perhaps even building a big Pressure Swing Adsorption machine and deliver it to Venus in sections. I am sure switching the main filter from nitrogen to CO2 wouldn’t be too difficult. I am sure it would take quite awhile for such a machine to filter Venus but by doing that and reducing the pressure and temperature by half would open up so many doors for additional ways to taraform.
Colonizing THE SUN :v
I did that in universe sandbox lol
How much CO2 in the air here before we suffocate?
The problem with mars is not the low gravity. It’s the fact that it doesn’t have a magnetic field. It currently has very little atmosphere because gravity is doing all the work and there is no protection from the sun blowing away most of it. If it had a magnetic field mars could have a thicker atmosphere. It would be thinner than earth as seal level but it would be akin to the atmosphere that earth has at on the peaks of some of the highest mountains. The magnetic field problem is what keeps Mars from ever being terraformed. If it did have a magnetic field and it can have a thicker atmosphere than it currently has humans can live there with minimal PPE. Maybe they’d have to use O2 bottles to stave off hypoxia but that would be it. Indoor spaces would be pressurised but the outside could be as lush as an alpine tundra biome could ever be.
can they let ice comets crash in to the planet? need a lot of them but could it be feasible ? question is answered at end video lol. are there plans for venus or is mars the only focus?
it takes time to terraformation the planet
I think Venus is a better bet than mars, I mean, if we thinned the atmosphere or cleared the clouds I think the tempature could at the very least become doable, and at most habitable, and we wouldn’t even need to make the atmosphere thicker cause there’s enough pressure for water to exist in a liquid state, all we’d need to do is lower the temperature and add oxygen and nitrogen
is it a scientific fact in the opening about oxygen?
Where is the nitrogen going to come from?
Solar shade for venus is best option for fixing atmosphere
More and more studies suggest that Mars had a more dense atmosphere and liquid water once. It is likely to be able to hold on to breathable atmosphere for a few million years (the whole human civ is what, 10000 years?). Especially if erosion is prevented. Yes, Mars is loosing most of it`s atmosphere to erosion due to lack of magnetic field rather then low gravity. Proposals to create artificial magnetic field with today`s technology exist.
That said, I would prefer Venus for terraforming too. As for removal of atmosphere, I think there is no golden egg, combining different methods and introducing them in the right order seems to be the most feasible. Starting from the top, where conditions are less harsh, so equipment has to be less durable meaning cheaper. Since both N2 and O2 are lighter then CO2, an air filled habitat floating on the dense CO2 atmosphere is quite possible. If autonomous, could be filled with He2. Once surface pressure and temperature would drop to a more acceptable level for machinery, autonomous plants would start the removal of CO2 from the bottom as well. Alkali Earth elements can bond CO2 to create stable molecules (rocks basically). In the meantime floating bacteria can brake down CO2 as well. Finally, with the introduction of H2, CO2 amount could be reduced further, creating water, which could stay in a liquid state if temperatures are reduced far enough. Even with all CO2 removed we would still have a roughly 3 atm surface pressure N2 atmosphere. Some N2 would eventually dissolve into the new ocean, the rest could be turned into nitrates by surface plants. This all done still leaves a few questions. Would settling on surface possible due to intense volcanic activity? Would the planet be cold enough for human life? Even with greenhouse effect removed, Venus still gets more sunlight then Earth? How would the temperature fluctuate between day and night?
Why venus? Why mars? we should try colonize moons like callisto, titan or maybe dwarf planets like ceres
Because the gravity sucks there.
To make Venus habitable and full of water there is no other option than option 2 (bombarding with hydrogen).
I wonder how much water is in the Venusian atmosphere? If we could point a few large comets at the planet, without risking a collision with the Earth, maybe we could start cooling the planet.
AWESOME
