Working theory: Mars cools down inside, iron core stops moving, few million years later the iron's magnetic domains contained inside the planet get unaligned causing the magnetic field to disapear.
I know, I changed the word RoadSTER to RoadSTAR as if to imply that at some time in the future maybe Tesla will build space cars called Roadstars. Nevermind...
Loui Coleman I mean, isn’t the current theory about how earth gained it’s heat from asteroid impacts that made it up? Crashing a bunch of large asteroids into mars could have a similar effect, likely. Maybe crash Ceres into it, and Mars’ moons?
I don't think there are enough asteroids in the solar system to make even close the earth gravity, it only has a third the mass of earth; if you added enough mass to bring it up to earth's it would no longer be mars. If we want earth gravity venus is the best option. Honestly it's probably a better choice.
Mars (and it’s moons) have a surface made mostly of iron oxide. If you remove the oxygen, and place the iron as dust, in a low orbit (think Saturn’s rings) around mars, that should produce a magnetic field.
All you have to do is send lots of robots and have them build a massive coil or permanent ring magnet at both poles. A magnet strong enough to attract the flux tubes/birkeland current from the Sun which might just reach and kick start the core of Mars to start generating its own magnetic field. So its not possible to terraform Mars until next century, colonizing Mars might take place in 23rd century after 100 years of terraforming in 22nd century using robots.
Here's an idea. Figure out a way to power several of these in space, ( www.sciencenews.org/article/spinning-core ) then launch them into an array sufficient to block the solar wind at a Lagrange point between mars and the sun. We'd obviously have to develop them a bit more to make them stronger and more efficient, plus get theme there, (falcon heavy anyone...) but there's your magnetic shield. Depending on the size of field generated, and the power requirements, this would probably be the best way to protect a ship from cosmic radiation as well.
Just slam some moons of Jupiter and Saturn into it. It would increase it's mass and gravity; remelt the planet and jump start the dynamo effect for the magnetic field; and Ganymede has oceans worth of water. While you are moving moons around you might as well give Mars own too so you can stabilize it's axial tilt.
The best theory on this is that about 4.2m years ago a asteroid or comet hit mars and stopped its internal mechanism. Some scientists and geologists believe that if it got hit by another asteroid of the same size it might kick start the internal mechanism again.
Maybe a practice run of terraforming the moon?? It'd be pretty sweet to moltenize the core possibly restarting the magnetic field. With the level of tech required for this we may as well farm the solar system for terraforming elements that are lacking.
2:40 Could 8 Liquid Salt Nuclear Reactors with direct convertor to electricity (LSR/DCE) be enough power t generate a big enough magnetic shield? 3:54 How about a LSR/DCE powered laser platform above the poles. I originally was looking for information on how would it be posable to jump start the core of mars. That would provide not only power to Deep Geothermal Plant with direct convertor to electricity (DGP/DCE) but threw that could provide power to granitic systems across mars to make it 1 to 1 earth type gravity.
@@skipperofschool8325 you are speculating ! i'm presenting Fact's ! Even if mars was terraformed has is ! Any Plant life would even if it was brought by humans has seeds , would be toxic for us humans ! it's earth is full with heavy metals! Your Evolved liver would die pretty quickly !
This is the first realistic terraforming plan I've heard in a long time. Most plans ignore the reasons why Mars died in the first place. Any attempt to restore an atmosphere without first establishing a magnetic field would only see the new atmosphere blown away just like Mars' original one. Terraforming a dead planet into another earth is a very romantic idea which generates donations for sketchy nonprofits which tend to be the sole source of income for the founders, and most plans just ignore the lack of a planetary magnetic field. So great to finally see someone addressing the central problem which has to be solved before any atmosphere generating scheme could work.
William Hearn meh, achieving stable orbit is all about speed + distance vs gravity. Go find a large roundish asteroid and tow it to mars... A larger moon should kick start mars' iron core and warm things up a bit.
We found a planetary core supposedly. Tow that to Martian moon orbit. We could mine resources for Martian development. It would block the solar wind. It may jump start Mar's core. If we can tow it there, we can also keep it in orbit. Science fiction only is fiction till it becomes fact. Computers you could put in your pocket were science fiction just a few years ago.
You could do that by slowly towing a large amount of small asteroids into orbit and pouting them into orbits that will slowly merge and not have a violent sudden impact. Depending on the size and makeup of the asteroid it could be impacted into Mars at a angle to increase the temp at one point. You would want asteroids that have a large amount of radio active elements of a very high density like uranium and thorium.
ImmortalNature777 I was researching this a few days ago too, and I found this video today :D Maybe they did it because of SpaceX launching the Tesla Roadster to Mars, and they knew people had questions of SpaceX colonizing Mars.
One of my more (admittedly impractical) ideas is to use nukes to kick-start the core of the planet. Basically hoping the beat of the explosions to remake a magma core..
Nuclear-powered engines, Fusion if we're far enough in the future. I think orbit could be achieved with the tech we have now, we just don't have the funding for a mission there.
that's why we haven't been focused on colonize Mars. the amount of work and resources to build a habitable environment there are not worth it! we are talking about a dying planet and humans that don't and probably will not have the tech to do terraforming in weeks or months to make this goal reachable. if we had a more friendly planet or moon we should focus on that. but we don't have in our solar system.
Maybe the earth will need the technology soon? What if there were a cosmic natural catastrophe that turned mars like it is now and Mars used to be like earth. What if the earth is about to lose a lot of it's atmosphere maybe or otherwise experience a strong solar caused disaster and then we'll have a friendlr planet withya moon (ours) that we should focus on NOW?
What boggles me, is if you put something in space and you want it to be fixed between the planet and the sun, you want it to orbit the sun and not the planet. This means that that object will have a smaller orbit than the planet it supposed to shield/act upon, which means it will orbit the sun more quickly. So you'd want to always slow it down in order to keep it fixed, which is rather impractical, be it efficiency, fuel its own shielding etc. So any solution of that direction is impractical. Or am I missing something?
I think we should do an atmosphere transplant from Venus to Mars when the red planet can actually sustain one. Just the Co2 to heat up the planet (it could even be the extra Greenhouse gasses from earth). Then we can introduce oxygen producing bacteria and then slowly more and more things beneficial for people. All the while people could live in domed cities documenting the changes, doing experiments, growing food, adapting to the martian environment. Slowly but surely finding answers to questions we still have.
I was thinking the same thing but just imagine the entire earth being clotheslined by a tube going incredibly fast, lol. I think it would actually be best to condense the gasses and ship them to a large space station in the planet's orbit, then down to the planet for necessary applications.
Too expensive and time consuming. You'd have to wait months for the optimal orbit path, and atm, rocket technology can't transport huge payloads cheaply.
Youd need to freeze the c02 solid and reheat it on mars for easy transportation, even then youd have trillions of tons of c02 to ship. On top of that venus surface temp is extremely high, you'd need to design ships to be able to get there and withstand acid rain, extreme temps, and hardcore conditions. Then you need to weigh the resource differences between 1 trips fuel vs how much atmosphere you are transfering, with todays tech that would be unimaginable amounts of fuel
I'm kind of disappointed Caitlin, by the comments about science fiction. A huge chunk of things we call science now, were first envisioned as science fiction. You have to imagine it before you can invent it and that's what the better science fiction writers do. They imagine it and then scientists invent it.
Robert Ohm I think the two influence each other. And everything’s is science “fiction” until it’s real, y’know. And some things may stay fictional forever, like lightsabers from Star Wars, cus you can’t really make light act like traditional steal swords.
Like zbrown02 mentioned, some of the best scifi writers were also scientists. They are able to use the current science of their time to envision what might be possible in the future, even if it is impossible when written. While Star Wars is science fiction, it was written by non scientists who chose to use things that were just cool, not things that were scientifically possible. A light saber could never do what it's portrayed as doing. But if you go back and look at the science fiction of the early 20th century, especially the space travel stuff, we can now do the things that the scifi writers of the time predicted, even though their critics derided what they wrote as impossible fantasy. That's just one of the reasons I don't consider Star Wars "science fiction". It's really fantasy that is set in space. I think the difference between science fiction and fantasy is that science fiction tries to use actual science as the basis for it's high tech and fantasy just does whatever it wants to and ignores the laws of nature. That's part of what I was bringing up in my original comment, the science fiction Caitlin was referring to does have a basis in science fact, even if we're not to that level yet.
I don't think she was bashing sci-fi or downplaying the importance of an open mind. I think you're reading too much into what was essentially an innocent comment. She was simply saying most of the other terraforming ideas are things that would require technologies that we can't currently conceive. She didn't say they would never be possible.
She said "And as weird and impossible as that sounds, it's not totally science fiction." I don't know how to more clearly say that science fiction is impossible. While I doubt that she believes that science fiction is impossible, based on the fact that science fiction from many years ago has become science fact today, what was written in her script, was poorly written because that is exactly what it says.
Hmm since the magnetic satellite wouldn't be orbiting Mars, I'm guessing it would be orbiting the sun. Having said that, the satellite would need to have the same period of revolution as Mars. Would that be possible given the different orbit sizes?
Yeah, only L4 and L5 are stable. In the real world they don't usually put craft at L1 because that means the sun is always directly behind, which makes communication impossible...so they'll put them in orbits around L1 instead, which also happen to be nominally unstable so again they wind up needing periodic station-keeping anyway. In this application though it looks like having the sun always directly behind is kinda the whole point?
In addition to the artificial magentic field, start harvesting and herding ice asteroids to impact the poles of Mars. This would melt both the ice in the asteroids as well as the ice underneath the dry ice. Kim Stanley Robinson used this idea in his Mars Trilogy books.
Why not both? And science - no matter what it's for (Generally), can complment the other sciences, and help push breakthroughs that otherwise, would've taken longer to find.
I agree however we must do both. It is imperative for the long term survival of the human race to become a multi plantet species. That’s a step to becoming a multi star system species and that is the best way to ensure the survival of the species from natural catastrophes. There are events that can destroy planets. There are events that can destroy whole star systems. It is very hard to find an event that can destroy multiple star systems at the same time. Just my 2 cents.
As much as it's tempting to do both the problem is that we don't have enough resources (in our hands) to make the earth a better place which is free of pollution and blood for all these things we are fighting about besides colonizing other planets we have enough resources not in our hands but in the hands of greedy governments' rulers who probably just don't care -_-
by the way regardless of what I believe about colonizing other planets I think Elon Musk is doing a great job for the good of humanity and the only reason I wish he is driving that mental and economic power to serve other things here on earth is because he is rare .i.e. there are not enough people like him who have the vision and the money to make things better on our planet
We would either have to increase its gravity from about .07 if I remember correctly,to 1.0 somehow. Or we humans would actually just have to slowly acclimate ourselves to its lower gravity over time.
Lack of pressure due to the relatively small size of Mars, caused its core to solidify. As the metals inside the core are "frozen" solid, there is no longer any motion to generate electromagnetism. Solution would be to either teleport or hyperspace-jump a sizable asteroid containing heavy metals into mars' core, this would increase the pressure and cause the core to heat up again. The rotation of the planet should slow a little bit, but this shouldn't have too much of a negative effect.
I love this channel. Short, fun, and informative as always. Now for some criticism: I've noticed the speaker in these videos always have exaggerated hand gesturing and I find it very distracting. I realize a little bit of gesturing is necessary since there's not much to see but maybe tune it down a bit? I always see a lot of up and down hand movements in these videos.
I massive impactor in Mars' northern hemisphere sent a shock through Mars and into the molten core and knocked out the flow of the core, reducing its magnetic field. Redirect Ceres into Mars in such a way in such a way that it not only knocks the flow back into its original state, but that the remnants of Ceres, becomes the natural satellite of Mars.
What if we live underground Mars? We could definitely set up a colony there on the side of a mountain. Doesn’t Metal & large amounts of dirt completely block radiation?
E Stolee A quick google search tells me that Lead, Concrete & Steel blocks Gamma Radiation. If we make our living homes on Mars IN the inflatable homes (do research on it, real cool stuff), then we could cover it with a later of rock or sand. Since there’s water on Mars, we can also make Igloos to put these homes in.
I'm glad someone somewhere is thinking straight for ideas. we need to start thinking about htf we gon keep the atmosphere instead of using up the remainder of liquids to warm it up...only to be lost again anyway. I say keep everything how it is nice and steady(ish) and figure out this first before doing anything too drastic.
Forgive me if this is a stupid question, but I have to ask. How would you keep the magnetic field generator between Mars and the sun? It doesn't sound like a stable orbit. I know solid bodies can become tidally locked, but I do not see how that helps here. Can someone explain: please.
In addition to the large magnetic generator positioned at the L1 Lagrange Point, maybe also have a hundred or so satellites with slightly weaker magnetic fields orbit the planet and different inclinations and altitudes to both give more rounded protection (like from cosmic rays and even radiation from Jupiter's wide-stretching magnetic storms) as well as an emergency back up system if something on the main generator goes wrong and needs to be repaired or replaced.
I know its a stretch, but let me give it a shot. Terraforming Mars would be simple. The solar shield can, and will work, however, what if that shield would fail? One would need a back up some how. I would suggest building an Electromagnetic generator on the planet. Underneath the surface would be a power system, running from the North to the South, generating an artificial electromagnetic field from the planet's core. Another generator would run across the planet surface from the north pole, to the south pole, acting as an exoskeletal power system, stabilizing the power generation coming from the core.
Build a small magnetic deflector unit (powered by PV's panels). Build lots of them and align them to deflect charged particles away from Mars in incremental amounts by shaping them into a cone (with the point toward the sun). Have them maintain their positions relative to each other based on the primary unit positioning itself between Mars and the Sun. (I've had this idea in mind for quite a while :-)
What's the difference between the strength and the size of a magnetic field? The distance until it drops to nearly zero? And since magnetic fields are theoretically infinite, isn't that the same as saying it's a strong field or a weak one?
I think there is another way to rebuild Mars' magnetic field that would be easier to do and be localized on the planet, that is to convert it's iron core into an electromagnet. This could be done by drilling a series of holes all the way around the equator a mile or so apart and down to the core and filling them with iron rebar (like they use in cement structures). Next install solar and wind powered generators over each rebar site and cycle electricity to the core at a rate of 60 hertz. The hardest part about this plan of course would be drilling the holes. Mars has alot of iron on it's surface so making enough rebar could mostly be done on planet. Another obsticle would be creating electricity on the night side of the planet if there is no wind, but eventually the magnetism would still build up over time.
Building a greenhouse gas factory on Mars would have to be done even with a giant magnet in space. Just increase greenhouse gas production and no magnet is needed.
We're going to build a magnetosphere and Earth is going to pay for it
I can imagine this is what planetary politics will sound like

Colonizing Venus seems far more convenient. Also, living in city-sized airships seems pretty cool.
but not the acid rains 😰
We should just like... crash a bunch of asteroids into it. It’d heat it up and make it closer to earth mass.
Some One whilst what you’ve said is technically true, the effect would be negligible.
Loui Coleman I mean, isn’t the current theory about how earth gained it’s heat from asteroid impacts that made it up? Crashing a bunch of large asteroids into mars could have a similar effect, likely. Maybe crash Ceres into it, and Mars’ moons?
Sure but Mars would be a molten slag a 1B years after.
I don't think there are enough asteroids in the solar system to make even close the earth gravity, it only has a third the mass of earth; if you added enough mass to bring it up to earth's it would no longer be mars. If we want earth gravity venus is the best option. Honestly it's probably a better choice.
Comets would be a better option - build up the water on Mars.
Mars (and it’s moons) have a surface made mostly of iron oxide. If you remove the oxygen, and place the iron as dust, in a low orbit (think Saturn’s rings) around mars, that should produce a magnetic field.
Sci show fix! Day enhanced. Cheers Sci show. 🤘😄🤘
All you have to do is send lots of robots and have them build a massive coil or permanent ring magnet at both poles. A magnet strong enough to attract the flux tubes/birkeland current from the Sun which might just reach and kick start the core of Mars to start generating its own magnetic field. So its not possible to terraform Mars until next century, colonizing Mars might take place in 23rd century after 100 years of terraforming in 22nd century using robots.
Who else wants to live on Mars?
me id love to colonise it
Very soon my friend!
Dude, I rather have cloud city on Venus.
Why would anyone want to? It's a desolate s--thole, there's nothing there. You'd be stuck inside a tiny tin can and space suits your whole life.
Ketsueki Kumori, same! But I'll settle for mars right now.
Less gravity makes you weak. Venus is closest one.
Here's an idea. Figure out a way to power several of these in space, ( www.sciencenews.org/article/spinning-core ) then launch them into an array sufficient to block the solar wind at a Lagrange point between mars and the sun. We'd obviously have to develop them a bit more to make them stronger and more efficient, plus get theme there, (falcon heavy anyone...) but there's your magnetic shield.
Depending on the size of field generated, and the power requirements, this would probably be the best way to protect a ship from cosmic radiation as well.
Throw some asteroids into mars snd boom you have a atmosphere lol
Just slam some moons of Jupiter and Saturn into it. It would increase it's mass and gravity; remelt the planet and jump start the dynamo effect for the magnetic field; and Ganymede has oceans worth of water. While you are moving moons around you might as well give Mars own too so you can stabilize it's axial tilt.
Good idea. If only we had a teleportation device large enough for celestial bodies....
Even if we could do that, the time it takes for the surface to stabalize would be in hundreds of thousands of years making this not an ideal option
How
We would need a lot of gravity to be similar to earth
Huh. Wouldn't that create a whole lot of dangerous asteroids...at least dangerous to where I live. Earth.
The best theory on this is that about 4.2m years ago a asteroid or comet hit mars and stopped its internal mechanism. Some scientists and geologists believe that if it got hit by another asteroid of the same size it might kick start the internal mechanism again.
Maybe a practice run of terraforming the moon?? It'd be pretty sweet to moltenize the core possibly restarting the magnetic field. With the level of tech required for this we may as well farm the solar system for terraforming elements that are lacking.
2:40 Could 8 Liquid Salt Nuclear Reactors with direct convertor to electricity (LSR/DCE) be enough power t generate a big enough magnetic shield?
3:54 How about a LSR/DCE powered laser platform above the poles.
I originally was looking for information on how would it be posable to jump start the core of mars. That would provide not only power to Deep Geothermal Plant with direct convertor to electricity (DGP/DCE) but threw that could provide power to granitic systems across mars to make it 1 to 1 earth type gravity.
Also imagine if we do colonize Mars and u have kids in there. Ur kids would be ALIENS.
Even if all the Martian problems where Fixed, Mars does not have the Gravity Needed to support Human Civilization ...
@@serenemountain6769 It does too. Mars has less gravity than Earth but it has more than enough gravity to keep everything on the surface.

terraformed has is ! Any Plant life would even if it was brought by humans has seeds , would be toxic for us humans ! it's earth is full with heavy metals! Your Evolved liver would die pretty quickly !
This is the first realistic terraforming plan I've heard in a long time. Most plans ignore the reasons why Mars died in the first place. Any attempt to restore an atmosphere without first establishing a magnetic field would only see the new atmosphere blown away just like Mars' original one. Terraforming a dead planet into another earth is a very romantic idea which generates donations for sketchy nonprofits which tend to be the sole source of income for the founders, and most plans just ignore the lack of a planetary magnetic field. So great to finally see someone addressing the central problem which has to be solved before any atmosphere generating scheme could work.
How about just giving mars a decent sized moon....
Jack Hammer that would be hard since Mars can barely hold on to the 2 "moons"it has.
That be more like giving a large planet a new moon called Mars.
William Hearn meh, achieving stable orbit is all about speed + distance vs gravity. Go find a large roundish asteroid and tow it to mars... A larger moon should kick start mars' iron core and warm things up a bit.
We found a planetary core supposedly. Tow that to Martian moon orbit. We could mine resources for Martian development. It would block the solar wind. It may jump start Mar's core. If we can tow it there, we can also keep it in orbit. Science fiction only is fiction till it becomes fact. Computers you could put in your pocket were science fiction just a few years ago.
You could do that by slowly towing a large amount of small asteroids into orbit and pouting them into orbits that will slowly merge and not have a violent sudden impact. Depending on the size and makeup of the asteroid it could be impacted into Mars at a angle to increase the temp at one point. You would want asteroids that have a large amount of radio active elements of a very high density like uranium and thorium.
We need to figure out how to put magnetic fields around spaceships so astronauts don't fry exploring the solar system 1st
It wasn't that hard to TerrorForm this planet though.
Get out!
Couldn't you just smash a comet into the polar ice cap?
I was just recently researching this causally, DOES SCISHOW HAVE THE POWER TO READ MINDS?!?!
ImmortalNature777 I was researching this a few days ago too, and I found this video today :D Maybe they did it because of SpaceX launching the Tesla Roadster to Mars, and they knew people had questions of SpaceX colonizing Mars.
No, it's just that every moron and his brother is currently obsessed with Mars.
episodes come shortly after news stories. that's why multiple channels release similar videos around the same time, fairly consistently
Christopher Lefont: Possibly, but I was looking up what solutions NASA had for terraforming Mars and it's quite interesting! :)
One of my more (admittedly impractical) ideas is to use nukes to kick-start the core of the planet. Basically hoping the beat of the explosions to remake a magma core..
I might have another good alternative idea: Let's protect Earth so we don't have to think about relocating to a dead rock within the next 200 years.
Mars is way over rated we should be looking to venus and cloud citys
Too hot, plus that icky protomolecule thing takes ships apart...
Cheezy Dee the higher in the sky you are the cooler the temp it would be a challenge yes but do able
bear adams Except there’s no way to suspend a cloud city high up in the Venusian atmosphere.
HaiImDan yea the oxygen /nitrogen air mix we breath and fill our ships with will float on the thick CO2 atmsphere of venus
Nuclear-powered engines, Fusion if we're far enough in the future. I think orbit could be achieved with the tech we have now, we just don't have the funding for a mission there.
4.2 billion years mars had a mental breakdown and everything went downhill
that's why we haven't been focused on colonize Mars. the amount of work and resources to build a habitable environment there are not worth it! we are talking about a dying planet and humans that don't and probably will not have the tech to do terraforming in weeks or months to make this goal reachable. if we had a more friendly planet or moon we should focus on that. but we don't have in our solar system.
Maybe the earth will need the technology soon? What if there were a cosmic natural catastrophe that turned mars like it is now and Mars used to be like earth. What if the earth is about to lose a lot of it's atmosphere maybe or otherwise experience a strong solar caused disaster and then we'll have a friendlr planet withya moon (ours) that we should focus on NOW?
We need to focus saving earth, mars is too far gine
Yo if the sun is the problem just get a giant blanket and cozy the sun in he needs sleep geez
How is this comments section not filled yet ?! Hello the video was uploaded 34 seconds ago where are those 600 first comments
What boggles me, is if you put something in space and you want it to be fixed between the planet and the sun, you want it to orbit the sun and not the planet. This means that that object will have a smaller orbit than the planet it supposed to shield/act upon, which means it will orbit the sun more quickly.
So you'd want to always slow it down in order to keep it fixed, which is rather impractical, be it efficiency, fuel its own shielding etc. So any solution of that direction is impractical.
Or am I missing something?
I like the LoZ reference.
But a hylian shield is too strong.

HYAAAAH!
Yet I fail to see the point 'sides catering to the nerd comm
“Should we?”
Um yes, for our own good we should definitely terraform mars
I think we should do an atmosphere transplant from Venus to Mars when the red planet can actually sustain one. Just the Co2 to heat up the planet (it could even be the extra Greenhouse gasses from earth). Then we can introduce oxygen producing bacteria and then slowly more and more things beneficial for people. All the while people could live in domed cities documenting the changes, doing experiments, growing food, adapting to the martian environment. Slowly but surely finding answers to questions we still have.
Just need that really long vacuum hose.
I was thinking the same thing but just imagine the entire earth being clotheslined by a tube going incredibly fast, lol. I think it would actually be best to condense the gasses and ship them to a large space station in the planet's orbit, then down to the planet for necessary applications.
neomew the ship from Spaceballs.
Too expensive and time consuming. You'd have to wait months for the optimal orbit path, and atm, rocket technology can't transport huge payloads cheaply.
Youd need to freeze the c02 solid and reheat it on mars for easy transportation, even then youd have trillions of tons of c02 to ship. On top of that venus surface temp is extremely high, you'd need to design ships to be able to get there and withstand acid rain, extreme temps, and hardcore conditions. Then you need to weigh the resource differences between 1 trips fuel vs how much atmosphere you are transfering, with todays tech that would be unimaginable amounts of fuel
"If there is life on mars and we terraformed it, we would basically be destroying its habitat" AS IF THAT LITERALLY EVER STOPPED ANYONE EVER LMAO
I'm kind of disappointed Caitlin, by the comments about science fiction. A huge chunk of things we call science now, were first envisioned as science fiction. You have to imagine it before you can invent it and that's what the better science fiction writers do. They imagine it and then scientists invent it.
Robert Ohm most sci fi writers are/were scientist
Robert Ohm
I think the two influence each other. And everything’s is science “fiction” until it’s real, y’know. And some things may stay fictional forever, like lightsabers from Star Wars, cus you can’t really make light act like traditional steal swords.
Like zbrown02 mentioned, some of the best scifi writers were also scientists. They are able to use the current science of their time to envision what might be possible in the future, even if it is impossible when written. While Star Wars is science fiction, it was written by non scientists who chose to use things that were just cool, not things that were scientifically possible. A light saber could never do what it's portrayed as doing. But if you go back and look at the science fiction of the early 20th century, especially the space travel stuff, we can now do the things that the scifi writers of the time predicted, even though their critics derided what they wrote as impossible fantasy. That's just one of the reasons I don't consider Star Wars "science fiction". It's really fantasy that is set in space. I think the difference between science fiction and fantasy is that science fiction tries to use actual science as the basis for it's high tech and fantasy just does whatever it wants to and ignores the laws of nature.
That's part of what I was bringing up in my original comment, the science fiction Caitlin was referring to does have a basis in science fact, even if we're not to that level yet.
I don't think she was bashing sci-fi or downplaying the importance of an open mind. I think you're reading too much into what was essentially an innocent comment. She was simply saying most of the other terraforming ideas are things that would require technologies that we can't currently conceive. She didn't say they would never be possible.
She said "And as weird and impossible as that sounds, it's not totally science fiction." I don't know how to more clearly say that science fiction is impossible. While I doubt that she believes that science fiction is impossible, based on the fact that science fiction from many years ago has become science fact today, what was written in her script, was poorly written because that is exactly what it says.
It would be WAY easier just to hit it with comets. Atmosphere would last a LONG time on human scales.

So we need to put sunglasses on the earth and give Mars an MRI.
Or... We could build an object, but just move it closer to the sun. Distance is key. Somebody do the math, I'm too lazy.

I was thinking if anybody thought of it, I looked it up. And they did!🔥
Hmm since the magnetic satellite wouldn't be orbiting Mars, I'm guessing it would be orbiting the sun. Having said that, the satellite would need to have the same period of revolution as Mars. Would that be possible given the different orbit sizes?
If you look carefully you'll see that it's supposed to be placed in Marses L1 Lagrange point.
en.wikipedia.org/wiki/Lagrangian_point
+Kitarae Ganymedess Lmao hope you're comfy under that tinfoil hat, mate.
Except L1 points are unstable, so you'd still need constant station-keeping and re-fueling.
+Myndale They are?
Yeah, only L4 and L5 are stable. In the real world they don't usually put craft at L1 because that means the sun is always directly behind, which makes communication impossible...so they'll put them in orbits around L1 instead, which also happen to be nominally unstable so again they wind up needing periodic station-keeping anyway. In this application though it looks like having the sun always directly behind is kinda the whole point?
How can you possibly move enough materials to Mars. We can’t even get enough truck drivers on our own planet.
I don't know, I always have a hard time believing people with facial piercings. I don't know why but that's just me

Drill into the core of Mars and explode a thermonuclear device. Voila, magnetic field!
Why don't we destroy Mars, then we can't go there so we don't have to think about how to go there. Problem solved, gib me nobel prize.
Making Mars habitable is infinitely more important than preserving whatever dead end ecosystems that might still be desperately clinging to life.
She just states the obvious in a very complicated way
In addition to the artificial magentic field, start harvesting and herding ice asteroids to impact the poles of Mars. This would melt both the ice in the asteroids as well as the ice underneath the dry ice. Kim Stanley Robinson used this idea in his Mars Trilogy books.
Humans care more about Mars than Mars ever cared about himself
Nice
HOWEVER I believe there are many things we can do here to make earth a better planet for living
Thanks for the great video
Why not both? And science - no matter what it's for (Generally), can complment the other sciences, and help push breakthroughs that otherwise, would've taken longer to find.
I agree however we must do both. It is imperative for the long term survival of the human race to become a multi plantet species. That’s a step to becoming a multi star system species and that is the best way to ensure the survival of the species from natural catastrophes. There are events that can destroy planets. There are events that can destroy whole star systems. It is very hard to find an event that can destroy multiple star systems at the same time. Just my 2 cents.
As much as it's tempting to do both the problem is that we don't have enough resources (in our hands) to make the earth a better place which is free of pollution and blood for all these things we are fighting about besides colonizing other planets
we have enough resources not in our hands but in the hands of greedy governments' rulers who probably just don't care -_-
by the way regardless of what I believe about colonizing other planets I think Elon Musk is doing a great job for the good of humanity and the only reason I wish he is driving that mental and economic power to serve other things here on earth is because he is rare .i.e. there are not enough people like him who have the vision and the money to make things better on our planet
The likelihood of any kind of event occuring which could make Earth less habitable than Mars is absolutely astronomical.
What could we do about the micro gravity? Everyone who discusses terraforming Mars to make it inhabitable seems to gloss over the gravity part.
We would either have to increase its gravity from about .07 if I remember correctly,to 1.0 somehow. Or we humans would actually just have to slowly acclimate ourselves to its lower gravity over time.
Should I have a MacDonalds burger tomorrow....? er... All the big questions... Yes, of course!
maybe we could send volunteers to build large electro-magnets at the poles to restore its field
Let the small scale experiments begin!
Terraform it! It’s dead, Jim. But we can bring it back to life!
We could totally give Mars a magnetic field. We just have to generate a planetary magnetic field.
Thanks, scishow lol -_-
Lack of pressure due to the relatively small size of Mars, caused its core to solidify. As the metals inside the core are "frozen" solid, there is no longer any motion to generate electromagnetism.
Solution would be to either teleport or hyperspace-jump a sizable asteroid containing heavy metals into mars' core, this would increase the pressure and cause the core to heat up again.
The rotation of the planet should slow a little bit, but this shouldn't have too much of a negative effect.
Love this. Great job.
I love this channel. Short, fun, and informative as always.
Now for some criticism: I've noticed the speaker in these videos always have exaggerated hand gesturing and I find it very distracting. I realize a little bit of gesturing is necessary since there's not much to see but maybe tune it down a bit? I always see a lot of up and down hand movements in these videos.
What mars needs is a deflector screen. My people can help engineer an equitorial deflector screen for Mars.
Hold on, if I remember correctly, the Earth is about 4 billions years old, so Mars lost its magnetic field when the earth was just formed??
Wonderful sci-fi for the time being
I massive impactor in Mars' northern hemisphere sent a shock through Mars and into the molten core and knocked out the flow of the core, reducing its magnetic field. Redirect Ceres into Mars in such a way in such a way that it not only knocks the flow back into its original state, but that the remnants of Ceres, becomes the natural satellite of Mars.
What if we live underground Mars? We could definitely set up a colony there on the side of a mountain. Doesn’t Metal & large amounts of dirt completely block radiation?
E Stolee
A quick google search tells me that Lead, Concrete & Steel blocks Gamma Radiation.
If we make our living homes on Mars IN the inflatable homes (do research on it, real cool stuff), then we could cover it with a later of rock or sand. Since there’s water on Mars, we can also make Igloos to put these homes in.
I'm glad someone somewhere is thinking straight for ideas. we need to start thinking about htf we gon keep the atmosphere instead of using up the remainder of liquids to warm it up...only to be lost again anyway. I say keep everything how it is nice and steady(ish) and figure out this first before doing anything too drastic.
Forgive me if this is a stupid question, but I have to ask. How would you keep the magnetic field generator between Mars and the sun? It doesn't sound like a stable orbit. I know solid bodies can become tidally locked, but I do not see how that helps here. Can someone explain: please.
Patrick star: WE SHOULD TAKE MARS AND PUSH IT SOMEWHERE ELSE
Why would we give mars a magnetic field, when earthlings are still chopping trees down for heat, and living in mud huts.
Lol
In addition to the large magnetic generator positioned at the L1 Lagrange Point, maybe also have a hundred or so satellites with slightly weaker magnetic fields orbit the planet and different inclinations and altitudes to both give more rounded protection (like from cosmic rays and even radiation from Jupiter's wide-stretching magnetic storms) as well as an emergency back up system if something on the main generator goes wrong and needs to be repaired or replaced.
Soooo what you're saying is we need to build a Death Star? Cool!
I know its a stretch, but let me give it a shot. Terraforming Mars would be simple. The solar shield can, and will work, however, what if that shield would fail? One would need a back up some how. I would suggest building an Electromagnetic generator on the planet. Underneath the surface would be a power system, running from the North to the South, generating an artificial electromagnetic field from the planet's core. Another generator would run across the planet surface from the north pole, to the south pole, acting as an exoskeletal power system, stabilizing the power generation coming from the core.
Build a small magnetic deflector unit (powered by PV's panels). Build lots of them and align them to deflect charged particles away from Mars in incremental amounts by shaping them into a cone (with the point toward the sun). Have them maintain their positions relative to each other based on the primary unit positioning itself between Mars and the Sun. (I've had this idea in mind for quite a while :-)
What's the difference between the strength and the size of a magnetic field? The distance until it drops to nearly zero? And since magnetic fields are theoretically infinite, isn't that the same as saying it's a strong field or a weak one?
engineer at NASA: LOL what if we like put an oversized MRI machine in front of mars, to like, you know block the suns harmful rays? could work right?
Whenever people talk about colonizing Mars, that's usually the major hurdle I bring up. Until we solve that, any terraforming would only be temporary.
In addition to this, I would bombard Mars with asteroids from the asteroid belt
Good subject and well presented.
I think there is another way to rebuild Mars' magnetic field that would be easier to do and be localized on the planet, that is to convert it's iron core into an electromagnet. This could be done by drilling a series of holes all the way around the equator a mile or so apart and down to the core and filling them with iron rebar (like they use in cement structures). Next install solar and wind powered generators over each rebar site and cycle electricity to the core at a rate of 60 hertz. The hardest part about this plan of course would be drilling the holes. Mars has alot of iron on it's surface so making enough rebar could mostly be done on planet. Another obsticle would be creating electricity on the night side of the planet if there is no wind, but eventually the magnetism would still build up over time.
Building a greenhouse gas factory on Mars would have to be done even with a giant magnet in space. Just increase greenhouse gas production and no magnet is needed.
