"Your blood would instantly boil, your organs would rupture, and there would be no oxygen, so you wouldn't be able to gasp with fright"
*HAPPY STOCK MUSIC*
Option 2, building factories on Mars, although it's expensive it sounds the easiest plausible thing humans can currently do. If humans intend to live on Mars, they are going to be introducing human bacteria later on anyways.
Agreed
i agree except us greedy humans and the dumb governments would overdue it and destroy mars too. I think we need to abandon the space race and start to build underground and underwater so we can save the outer area of Earth then we use nuclear power for our benefit instead of for war.
+Grady Burkett *overdo
+Grady Burkett HAHAHA destroy mars? are you serious? Its a wasteland. Build baby build. We create value by creating stuff
Darcy Robbs lol you know what i mean. judging by what we did to earth, i think we can do things unimaginable to mars
I can see trump watching this and thinking to himself
"No One can build colonies on Mars better than me. Nobody knows Mars better than me, Martians love me they're great people. I will build the greatest colony on Mars, and Venus will pay for it"
I'm fucking done 😂😂😂😂
#MakeMarsGreatAgain
HAHAHAHAHAHAHAHA
and I can see you being a dishwasher in the kitchen in the hotel there dumbass!
Trump supporter? ^
I think biospheres would be the way to go. Creating entire cities under protective domes seems more feasible than trying to change the entire planet.
+20teamplayer I agree with you, because terraforming will take thousands of years... And biosphere probably 10-50 years if they wanna do it fast.. It will cost a lot of money tho.. Hopefully MarsOne project is still live and about to go there. Can't way for their first rover to launch..
+20teamplayer They both have their engineering difficulties. Terraforming requires changing the atmosphere's composition. Biospheres are expensive and take time to build, not to mention sending rockets there with the necessary materials and equipment for such a structure, as well as the personal to construct it.
***** Agreed, but it just seems a bit more feasible. Even if you changed Mars's atmosphere, what's to stop the solar wind from once again stripping it away. How would we restart the planets magnetic field to protect it? Reheating a planets core is a tall order.
We could hit it with something big.
***** To do anything to the core that impact would be so big the planet would still be uninhabitable for 100/1000 of years. It would be like the big piece that hit earth and created the moon. It still think biospheres are just a more feasible option.

Whats the point of Teraforming Mars if it has a weak Magnetic field? You would loose the atmosphere.
This. I feel like this is an extremely large problem that is heavily overlooked. How tf is anything supposed to live there if it is constantly being barraged by radiation? Not to mention the atmosphere will be constantly decreasing as it is stripped away. Maybe huge biodomes? Large dome-like areas where earth plants can convert the thin CO2 atmostphere into usable oxygen? Really expensive, not entirely practical. Will that stop us from trying? PFFFFT no! I'm an undergraduate aerospace engineer with a big dream of helping to put people on mars.

would it some how be possible to increase the planets rotation to start back up the magnetic field around the planet that would also help with the gravity
Trace, why are you worried about "contaminating" Mars with human bacteria? If people do eventually live on Mars without spacesuits its going to be contaminated anyways, right?
Lucas Johnson Yea I'm not seeing what people have about "contaminating" Mars. First off, it's dead as far as we know. Second, just like earth, evolution will take place regardless and adjust things accordingly. Only issue is what happens when we drag Mars-evolved bacteria back to earth?
Space rocks amenable to carrying bacterial life have been travelling from Earth to Mars and vice-versa since the end of the Late Heavy Bombardment. Planetary Protection is pointless.
@@aaronibarra400 What if it isn't though?
Wait.. what? You don't want to bring bacteria from humans to mars, but you want to bring plants to mars, so you can enjoy life on mars without spacesuits? What?
So the problem with contaminating Mars too early with bacteria is that it can undo all the hard work. When you terraform a planet, you have to be very careful about the bacteria and the plants that you introduce, and when you introduce them.
Imagine if you contaminated Mars with a bacteria that out competes another bacteria you would use to create oxygen. You'd have to deal with the first bacteria on a planetary scale. It would be very difficult.
Lutranereis
Ah. Of course. Thanks for explaining it.
RaDnWave No problem, I'm quite a buff about terraformation. It's been an interest of mine for a long time.
This is the most civil conversation I have ever seen on the internet...
AFR0PR1NC3 You know it's pretty bad when you see two people being respectful in a discussion and are *surprised* by that.
If Mars were to be successfully terraformed, with its water and new Earthlike atmosphere, the dust storms (4:13 - 4:16) that happen now likely wouldn't happen then.
Unless it's Darude Sandstorm
vertexercy
You will be eaten by Venusian honey bees.
it is happing now there is water and clouds on Mars
True the presence of liquid water and possibly an ocean would pretty much eliminate global dust storms.
We just need to bring a lot of potatoes and poop.
ironcityblue lol
No bring Tom and jerry tehy can survive
At least a Martian space suit would not be as complex as an Apollo moon suit. Mars does have some atmosphere, so the suit would have to keep the user warm and pressurized, as well as supplying air. I can't imagine an astronaut needing a heavy heat radiator like they would on the moon. Especially since it can get up to 85 F, nice. Mars could have been another Earth.
+twistedyogert it would be colder but yeah it could have been
+twistedyogert The Apollo lunar suits did not use "heat radiators", they used porous plate sublimators in their PLSS backpacks. The outer layer of the lunar suits were made of Beta cloth, Teflon coated microfibers, and were white in order to reflect most of the solar heat radiation. They were able to reflect away up to 90% of the solar radiation. Despite the fact that all the Apollo missions were scheduled at lunar dawn, to complete their missions before the lunar surface had a chance to heat up to its maximum temperature, the only heat that was an issue was dissipating the astronauts' own body heat inside the suits. This was accomplished by circulating cool water through an undergarment that contained several meters of small plastic tubing running throughout the garment next to their skin, and pumping the coolant through the sublimator in the backpack. The water removed the heat by seeping through pores in the sublimator plates, which turned to ice when exposed to the vacuum of space on the moon, and then instantly turned to a gas and dissipated into space. Quite an ingenious device that was developed specifically for the Apollo program.
i agere
We need to drill deep into the planets core and place our nuclear arsenal in many strategic locations to go off and reheat the core kick-starting a magnetic field. Then we need to bombard it with a lot of asteroids, especially around the poles. Then we need to start up fossil fuel power plants, the people on Mars will this far live inside air tight quarters and all vegetation be in large bio domes/greenhouses. When vegetation can start growing outside we will start to get the oxygen we need in the atmosphere!
Oh god .-.
Irradiated volcanism?
Kyle Drewry Earth's core is still hot because of radioactive decay, so that should not be a problem! Besides volcanoes never release anything non lethal anyway...
Drill deep into the panet's core, a few thousand miles deep? We can't even drill deeper than a 10 miles on Earth!
Thermospecialist Might be able to do so if we don't have an active magma core to worry about.
I´m no scientist, but why can´t we just find a way to grow plants in the martian summer? If we can mutate things we sure can mutate a plant. Plants take in CO2 which is most of Mars, they make photosynthesis (They also have night and day) and BOOM! Oxygen. This may not be possible, but it would be worth thinking.
The problem with that is that Mars' atmosphere is thin. Plants can't add atmosphere to a planet, so even if we could breathe on the surface, it's meaningless unless we can also have a similar atmospheric pressure to Earth's.
Lutranereis very true was about to say something similar before reading ur comment
Oh, okay.
Plants require Nitrogen to grow
Because plants filter the atmosphere but there is no atmosphere on mars or at lest not enough to matter.
It's going to take a lot of effort to terraform Mars.
THEY WILL RAISE YOUR TAXES. -- - -WHY NOT GET NASA TO FAKE TERRAFORMING MARS LIKE THEY DID WITH APOLLO ? ? ? ?
Actually it could be easier than we think.
Cesare Vesdani it’s alright bro I will be king
Archangel Michael more like “Money/War” if he US government wasn’t such a over compensating shit storm we could have been put half the money from the US army into nasa and could of been to mars by 1990.
LOUIS STEFFEN well there is no evidence of NASA faking Apollo so
have they found the traveler yet?
Nicholas Eisenhower i get this joke because i play destiny
No bungie stole it :(
Nicholas Eisenhower Gotta open a loot crate to find it
Is that Darude - Sandstorm in the background?
Yeah, I played spore. I can understand this!
Lol
Mee 2
im so happy im not the only one.
SPORE IS REAL :D
love your channel! thanks for all the hard work!
Plan to live on Mars:
*Throw an asteroid at it*
Bacteria screw up the planet? Isn't Mars screwed already, no life, almost no pressure and atmosphere. So what would the factories and bacteria exactly do to Mars to screw it up?
+Unlimited Crew He means that we may screw up the chance of developing life on Mars with a healthy environment.
+Xinbiel so if we will terraform mars to an "healthy" plant, earth will become our wasteland?
+BlackLight7 I reckon most Atheists would flee earth, so it would be a religious war zone lol
***** Lmao, I like you version of events better, but lets be honest, if Mars was completely terraformed and the Americans were the first ones to arrive, they would just nuke Earth and wipe out all their enemy's while they have the chance, inadvertently killing all their allies at the same exact time.
+Jim Kang "worlds war 1" lmao
What if an intelligent species came to planet earth, modified it to make it warmer and more cloudy, and then introduced the first organisms like algae and bacteria? :O
That's called "directed panspermia," and is one potential hypothesis for the appearance of life on Earth. Though, it's probably not very likely.
***** Because observing animals in their natural habitat and watching what they do on their own is far more interesting than putting them into a cage and telling them what to do?
***** Well its quite possible that they didn't leave us alone, Its quite possible they came here to make it habitable and support life, and then stayed here, for some time at least. Or may be they are still here, they might have been our ancestors at some point. Its all possible. They might have had interstellar technology, and moved on, or they might have come from mars in the first place. We don't really know enough about earth's history to say anything, we can only speculate.
Maybe they died.
***** maybe they were experimenting with earth then forgot they were terraforming it after having to wage a interstellar war against another interstellar society. At some point we might eventually find a piece of they're technology and then get sucked into a Galactic universe Kinda like Mass effect's.
Trace,you are one of the cooest people on you tube. Thank you for sharing your greatness with us. we all love you bro
Question: wouldn't Mars need a moon, or two?
1:38-Mars need an ozone layer, which it does not have
Is mars had grass more running water ect it wouldnt have dust storms.
true
The dust storm's aren't as violent as media depicts and they happen every 3 earth years or 1 and a half mars years.
The atmosphere is so thin that those dust storms would only feel like a light breeze if you stepped outside in one. That was the main scientific bending of the truth they had to do in The Martian.
If it had cows, we could milk those! Another problem solved!
Apparently this Earth is doomed if they're so much interest in relocating.
That's what I conclude from all this. They know something we don't.
+Brainbuster Maybe people will be on Mars by the time Yellowstone goes up.
+dynelol If Yellowstone had a mega-eruption, all it would do is make life inconvenient for a few years. The only reason anyone cares is because we Americans like to pretend the World revolves around us, and couldn't possibly survive without our help.
+Interstellarsurfer You seem like one of those people that think "So what if the temperature of the planet drops by 15-20 degrees? I'll just wear thicker clothes and the world won't be as bright for a decade or so. I'm tough. I can handle it."
And depending on where you live and your level of perseverance, you might actually be able to handle the temperature differences. PLANTS CAN'T! When most of the world's crops are dying because of the change in climate, food will become very expensive and very scarce and A HUGE amount of the world's people will die of starvation. There will be people who make it through it but it won't be as high of a number as you like. The LUCKY people will be the Americans that are closest to it and die either instantly or almost instantly.
I didn't say everyone will survive. Those that do, will collectively shrug, and move on. Thanks for the epic-length reply, btw.
+Interstellarsurfer lol trollin' teens
very interesting episode, and one of my most favorite topics.. I had just had a conversation with two different people about this. It was in the paper about the possible life on mars through the frozen waters they have recently found..
It kinda annoys me when people say mars has no atmospheric pressure to speak of while it may not be that much mars still has a thick enough atmosphere for skies, parachutes, and even in some cases small amounts of liquid water (even if it only last for a couple of hours)
Won't we just lose the atmousphere into space?
The gravitational put keeps some of it there
Yeah in some billions of years...
***** it takes a molten metal core to initiate a magnetosphere. on earth is is kept molten by both radioactive material and pressure, slamming a bunch of metal onto the surface won't do the trick
I like waffles.
I've never tasted them, though.
Lol
Blue waffle. that is all.
I like TURTLES!!!!!
TIGUR WOODEN Ikr , so tasty!
Please return to Pewdiepie. All of you.
I'd love a follow up on re-creating a functioning magnetosphere on Mars. That topic is rarely discussed. Thanks!
Watch the movie the CORE its easy !
Trace could you do more videos about terrafroming and how the process would work for each individual planet/moon. I am fascinated with this topic and have heard of other planets/moons that could be terraformed (Europa, Venus, etc.) and would like to here a more intellectual explanation of how to do it. Also you guys (DNews) should do some videos on planet colonization and Paraterraforming (putting something around the planet, glass or metal, to keep in the atmosphere). Because like I said before it would be cool to here a scientific explanation on how we could feasibly accomplish these things, if not far-fetched.
It's much easier to simply build a space station such as Elysium or cloud cities above Venus...
rock3tcat (ⵙⴰⵔⵓⵅ) yea but for some reason everyone is focused on mars, Venus would be great if we began developing cloud cities or colonies. It would require a lot of drones to do mining however.
can you explain more or point me in the direction of a video about that?
???
Blair Monkman
I was thinking more in how in the case of a space station or Venus colony we wouldn't need to worry about the long term effects of reduced gravity on the human body.
rock3tcat (ⵙⴰⵔⵓⵅ) Whatever happens now anyway everyone seems to be wanting to go to Mars and all the plans and ships people are making is catered towards travelling to Mars, the main problem with living in a Venus atmosphere is maintaining a city in the sky eg. how the heck will it float and what kind of power source will be used? However there would be benefits like there would be 0 deaths by nature or natural disasters
I like the mirror idea but I have another way to dramatically lower the cost. Build a gigantic island of solar panels on one of our oceans and use it to power a super strong laser shot at the surface of Mars. The laser would heat the area it hits so hot that the iron oxide starts to melt. Once a lake of molten iron oxide forms, send a spacecraft with a factory setup to plant itself near the molten iron oxide. The factory uses a gigantic array of heat energy based thermocouples to create gigantic electricity. This electricity is used to perform electrolysis on the molten iron oxide. This releases a TON of oxygen into Mars's atmosphere. As an atmosphere begins to form, the planet becomes warmer and the ice caps melt, releasing even more atmospheric gasses. The atmosphere would be about 70% oxygen, 20% water, and 8% CO2. The rest would be trace gasses. Carbon is pretty rare in the universe but some asteroids might have methane in them. Tie some nukes to the asteroids and propel them into Mars. Nitrogen is even harder to get but certain nuclear explosions can artificially convert elements to carbon.
I like you knowledge but do you think NASA will listen to us? They say that mars is lifeless and inhabitable planet and we believe in their words blindly. Who knows? Mars might be just like earth and they have even send some VIP over there. and the photos which they shown us of mars curiosity migh be edited. You can even make earths pjotos to look like mars by editing.
Mark Muncher They probably won't listen unless we had a had a ton of money and/or had a long resume of astounding successes. There is a small chance they might without though if you can make a case for it. Show them/ the data and cross your fingers you know?
Not good, that sort of laser might punch a hole in our ozone layer.
Jans Losn Lasers actually help with rebuilding the ozone layer:
events.nytimes.com/learning/students/scienceqa/archive/20001102.html
As long as the laser is not made of UV, it would be fine.
McGuyver Workshop interesting, but won't it super heat the atmosphere and cause rapid climate changes.
This gave me hope
Thanks for the info. Interesting
Melting the icecaps would be a terrible and short sighted idea.
But no discussion of Terra-forming should even be considered until we can go there easily and determine the actual state of the planet as far as possible deep subterranean or other life past or present might be concerned.
If we were to melt the icecaps that would be a very short term solution and once gone there would be nothing left to replace them.
This guy ends up purposely introducing the very same organisms he said would be bad.
Hey Kate F, don't you have an opinion on any of these things?
Certainly a cool video, and terraforming Mars is something to get kids thinking about now, as it's their generation that will do it.
Your favorite is option #3 - smash it with comets. I agree that it's a pretty cool idea. However, option #2 is, I think, much better.
With option #2, as you mentioned, we have the technology now. Further, your reasoning to object to this one - that we'll end up contaminating the planet with bacteria - seems moot for a few reasons.
First, by the time we have technology developed to steer a comet into Mars, which can be far in the future, I would hope we'd already have colonized the planet, and thus, our bacteria would already be there. Like the illusion of control Jurassic Park taught us, we might like to think efforts to keep bacterial from colonizing too once we get there could be fail safe, but just like the T-Rex, they'll get out of the park.
Second, isn't the goal of terraforming so that we could, one day in the future, be able to walk around Mars with a breathable atmosphere, nice temperatures, and enough pressure to survive? If that's the case, wouldn't the end goal be to not need a space suit and walk around freely, and thus, getting our microbial bugs everywhere anyway?
Third, another goal would be to eventually be able to grow plants (specifically food crops) on the surface. First, it would be with atmosphere controlled greenhouses and biospheres, but eventually, a long term goal would be to have an atmosphere the plants could live in, with soil they could grow in. Can't make that soil part happen without active bacteria.
Fourth, our solution to getting oxygen in the atmosphere won't be just one solution, but a portfolio of solutions to speed up the process. One of the best producers of oxygen, and what's responsible for our oxygen rich atmosphere here on earth is, you guessed it, bacteria. Many bacteria produce O2 as a waste gas. If we could get stable colonies of these oxygen producing microbes on the planet, they would greatly help terraform the planet sooner.
Many who look seriously at the question of how to realistically terraform Mars have realized that before we can make the planet suitable for humans, we'd first have to make the planet suitable for bacteria.
The bacteria mutating, by the way, is no more a concern on Mars than it already is on Earth, which isn't that high of a concern. Bacteria strains mutate constantly here on Earth, and while I wouldn't say it never causes problems, it wouldn't be a reason to scrap a terraforming plan. While there's more UV reaching the Martian surface, and thus, mutations would likely happen more often, that doesn't necessarily mean a super bug will develop on Mars and stop us in our tracks.
Good video, and great topic!
+MrLundScience but there is still problems like mars being small planet so most of terraforming would just fly away as the gravity cant hold em, unless we go with heavyer gasses but we cant breath those... the the lack of magnetic field so even the slightest of solar winds will fry all electronics and somewhat life forms so that is not good. option 3 would be nessesary to make mars livable make it bigger and heavyer first maybe get core melting with some bigger asteroids then start dreaming of habitable atmosphere.
MrLundScience I
MrLundScience
We will be lucky if we can still afford airliners in a few decades let alone this sci fi nonsense.
Very good presentation by a very good presenter.
How was the air pressure situation fixed? wouldn't like your organs and stuff still rupture?
What about a magnetic field? Mars doesn't have one and it seems to be pretty important here on earth. Could we get by with out one on Mars?
We haven't done many studies on that yet, but preliminary results would suggest the risk of cancer would significantly increased over the course of a lifetime. However, if we develop a cure for cancer, or even genetically modify humans to be resistant to cancer, or resistant to radiation (a proposed plan for colonizing Mars), then we'd be fine.
Lutranereis
well the magnetic sphere is requred to hold an atmosphere.... otherwise the solar winds would just blow it off
RustedCrown11 Think of it this way: It took about 2 billion years for Mars to go from potentially habitable with a thick atmosphere, to the red planet we see today. So if we could increase the density of Mars' atmosphere, we'd have a while to figure out how to keep it.
Lutranereis cool point.
i wonder if warming up mars will somehow re-ignite its core?
Lutranereis there in now proof a human can live on mars. It still misses the fact if a human gives birth to child
In less than 5% gravity that the child will be a weak human. Due to the lack of gravitational force. Also the earth has a magnetical force that protects it from many space rocks, and the solar winds. There will never be a physical way for a human to live on mars without the aid of a dome house that provides air and keep our bodies from freezing to a cold brick. There is a list of things that makes living naturally on mar impossible. Most plants that are on earth would have a hard time growing from the lack off energy from the sun.
Humans are still trying to kill the cannibus plant that provide oxygen. No way we can populate mars when we have homeless ppl on earth, why would you spend millions of currency to attempt something that is naturally impossible. Also the temperature on mars is way to extreme for a human. Mabye in a trillion+ years when mars gets closer to the sun, then we would be able to live on mars, if its still in our galaxy
Terraforming mars would be a total waste of time because mars has no magnetosphere to protect from solar wind and cosmic radiation meaning even with a breathable atmosphere you would still not be able to walk outside without a spacesuit to protect from radiation (assuming a spacesuit would even protect against that) and even more importantly without a magnetic field around the planet all the remade atmosphere would simply erode back into space eventually making the whole process a waste of time !
He said that in the video........
+anno636
1. No, with a thick atmosphere is excellent protection against radiation. No magnetic field required.
2. Yes, but it will only happen on the timescale of millions of years, so it's irrelevant to us.
Quantum Space It would take millions of years for the atmosphere to be stripped away, so who cares
Thank you! You understand what they really should do. Any ideas on how todo that??
Learn how to use punctuation.
Cool!!! I have a few days off between X-mas and New Year so if they can speed things up a little maybe I can visit Mars, too?
HI!
why to mantion about speed rotation change after comet hit?
and no need to to asteroid belt, comets get close every 2-3 years.
also we ca use a jupiter moons, one of them or few. It will look like a space billiards.
(noo need big engins to change orbit, it is dum(but can work)) more likely small space craft hiting a asteroid who will hit bigger asteriod who will hit a moon, who will hit a mars or venus.
what to you think abuot it?

because this video came out alittle while a ago so just let it set up
"If you were able to stand on Mars as you're dressed right now..." ... the one time I'm not wearing pants XD *facepalm*
How would we be able to restart the magneto-sphere? I know that it's something to do with the core so we have to melt it (because it's probably solid) But anyway how?
Mars is a lot like a cold desert. In the summer the temperatures can range from -40 to 80 degrees Fahrenheit, so theoretically you could walk outside with an oxygen mask on and nothing else.
Then when we get there, the real Martians show up from their century long vacation, and are like "wtf?"
Ok, stop - stop... Evidence is mounting that Mars was warm and wet some time back, but Mars has (I forget) either a weaker magnetic field or no magnetic field, and solar wind basically blew all the atmosphere away. Before we start working out how to ship a Brazilian tons of nitrogen to Mars, wouldn't it be a good idea to figure out how we're going to keep it there this time? Your water bottle is empty because it has a hole in it. Before you figure out how to add water to it, figure out how to patch the hole.
so, we cant plant plants? i mean, i know water evaporates on mars, but lets just say we already have rooms and water and we've soil. so, we plant the seeds in the room, they start turning co2 into o2, and then opening a door into the martian world, there could be o2 on mars, right?
Is it possible to increase the temperature of atmosphere by heat of mars core itself or terraforming mars by machine like world engine seen in man of steel movie?

It would probably be easier (and more ethical) to augment ourselves to various environments in space
Alright. You augment yourself and go live in a vacuum. I'll stay as I am...
How would it be unethical to alter Mars?
The ethical rights of barren planets to remain barren. Don't make me laugh.
you have try creating a human that does not need to breath(or be able to breath a small amounts of Co², doesnt get greaty weakend by the gravity survive over 100 bellow 0 degrees survive the global dust storms/ meteor showers doesnt have to eat, and a whole lot more, it will be a bit harder then you expect, so which do you think will be easier?
Its not unethical , if we are going to live there we would need to alter Mars to certain degree.
Does Nuclear missiles works instead of using a frozen comet which is merely impossible to gather or obtain?
A magnetically shielded dome with a pressurized atmosphere would be a very great idea. That is assuming we can create Magnetic shielding. I have not even brought maintenance and potential hazards that would be a active threat in this equation. Though if we can create a domed habitat, we can have a colony actively living on mars while the terraformation process goes on for the next century or two.
That quick theoretical explanation of how to form a magnetosphere didn't sell me at all. No magnetosphere, no breathable atmosphere; period.
What if aliens did this with earth billions of years ago
Technically we are aliens, as life most possibly came from an asteroisd, and evolved into many different creatures.
ArchGamer Its just that out of most hypotheses, this one is one of the most likely and most sensible
ArchGamer What I was just trying to say is that life on Earth most likely came from space any way and yes, I do have evidence. Just look through Scishow and Vsauces older vids. Idk why you insist on trying to egg me on or something.
How does the Melting the polar ice work? water instantly boils off because of low pressure. So, Do you mean than the eventually, after enough water vapor has formed, there will be enough ice remaining in the poles to form liquid ocean on Mars. Is that how this process works.
As far as i know you cant do any of these options as mars dose not have a powerful enough electromagnetic field and the atmosphere would be lost to rays bombarded by the sun, correct me if I am wrong ??
i keep on getting playback error
Yeah me too
in 500 years living on Mars will be normal
Could we not alter the trajectory of a comet coming out of the oort cloud to air bust through mars atmosphere both creating a massive heat increase and adding more water to the planet?
love your vids
No matter what you do , you can't make mars a livable planet.
Thank you! It's such a terrible candidate for habitation.
Name a better option other than Earth
Connor The Moon.....JK Mars would probably be the second Earth....scientists just need to figure out how TO make it like earth
Literally every planet in our solar system other than the Earth is a terrible candidate for habitation, we just have to pick the least terrible, and I think Mars is among those.
The moon has a minute atmosphere, can it too be terraformed? DNews
Yes, it could be, but it would be extremely difficult. First of all, there's the moral and ethical implications of slamming asteroids into something so vital to our planet's workings, but assuming we could safely do that, it's just the start of the problems.
The Moon has such little gravity, and is so close to a planet with much greater gravitational pull, that we would have to have some kind of system to replenish the atmosphere. If we expect people to live on the Moon, then we can't slam asteroids into it on a regular basis, so we're going to have to come up with a better way.
One way would be to created a moon-wide dome that would keep the atmosphere in. It would have the added benefit of being able to squeeze down, adding pressure to the surface of Luna and allowing us to live comfortably on it. The engineering for designing such a structure isn't far off, but the logistics of creating a dome, and the material science needed to make it light and strong enough, is well out of our grasp.
Additionally, Luna doesn't have a magnetic field, so we'd also need to build protection against solar radiation, which again could be addressed by some kind of massive dome.
Luna would be a beautiful place if terraformed, though. Most of the dray land would be on the far side of the moon, so you would have spectacular views of the sky at night. By the way, nights would last for two weeks, and days would as well, so that would take some getting used to. Also, the Moon would become more reflective, so we'd see a much brighter Moon from Earth.
Lutranereis Perhaps dumping heavy gases (industry?) could help to form an atmosphere as suggested in the video, nonetheless whether solar winds would tear it apart and make it impossible to maintain/regulate is hard to answer... anyways interesting read
Kingsley Hall I still think the dome idea is best, but some have proposed that we use the heavier noble gasses, which would stick better to the surface of Luna, to thicken the atmosphere. However, we could only create those using nuclear fusion.
Lutranereis Even with the dome we'd have the problem of humans having elongated spines and other bones also muscle's Being much weaker and The heart would be Significantly Weaker so if they wanted to travel they'd have to go to a similar place Maybe one of mar's moons?(I think it has 3)
Firnen Oftheages Mars has two moons, Phobos and Deimos, and the lighter gravity would be problematic, yes.
If you gradually reduce the gravity instead of all at once you could get people acclimated to Mars gravity. Created sectional rotating space station at mars. With 12 sections you could do it in a year first month at 1g then each section slows down 0.05g.
The small step G reduction would help and centrifugal force can be used to simulate gravity inside the station.
ive got a question, would it be possible to give mars an artificial moon or something so that it could afect mars's molten core to bring back the magnetosphere? as far as i know, our moon plays quite a big role in earth's volcanic activity
I think it's easier to terraform Venus
+Yang Junhai So u know nth about Venus.
Venus has huge global warming problems. In day it's wayyy to hot and at night wayy to cold
+Helena Travis Actual Venus is just as hot on the night side. The planet has a Jetstream in the upper atmosphere that blows at about 350km/h. This is because as soon as the night side starts to cool the difference in temperature between the two sides of the planet causes massive winds which equalize the temperatures. We don't see these super winds on Earth because our atmosphere is only 1/92 that of Venus'.
Hopefully we won't screw up a blue Mars.
+안나리 we will screw up mars we destroying earth so we do any planet we land on sad an true. Stay on earth an just lets us go extinct an let the universe live on .
+Bootleheadian Gaming Sounds like the best way to go with things.
+Bootleheadian Gaming or instead Of sacrificing possibly the only living intelligent life we could send people who don't twerk, scream YOLO and so stupid shit. Like Noah's ark. But way cooler
+안나리 oops we already screwed it up
+Evan Sines It wouldn't surprise me.
Going to mars today natjezzy lol 😘this is a good video
i can't speak for the magnetosphere but as we develop plant life on mars wouldn't the roots of said plants hold the soil in place and eventually stop the dust storms?
It's much cheaper to preserver Earth.
We can stay on earth forever 😐
@@justanotherbigfootwithinte4364
To transfer the earth inhabitants to Mars would not be more feasible than the terraforming
@@alainrobillard4300 agree but this is not solution..We are not here to born and die on earth...as this civilization. Get. Advanced maybe you will wake up one day and read your own comments in 40th century
Seriously? Barely 5 minutes and you call this a big episode???
+YiFan Tey 😎😎
"Big" isn't based on its size, but on its importance, in this context - obviously...
um question with the comets/asteroids if u don't want to introduce new bacteria how would u know what bacteria would be in the asteroids/comets that wouldn't burn up when it hits the planet?
Do human bodies actually have problems in low gravity or do they just have problems in high gravity after theyve been in low gravity for an extended time?
a cup full of nano robots could do it.
No Thank You Earth Is My Life💙💚
may we meet again
To control Mars we would need to introduce a moon the size and density of Ceres to stablize its tilt. So, how do you move Ceres to the correct distance?
Many of these issues were covered in Kim Stanley Robinson's very good series of novels, Red Mars, Green Mars, and Blue Mars.
Fastest way to colonize Mars is to drop a custom atomic bomb instead nuke to warm up the planet faster
Only to later find out that we killed the extraterrestrial life that existed on Mars lol
Gonna sux being a Martian exo-mite. lol
It would be better to crash some asteroids to create heat than to make the planet radioactive with some bomb.
And made the planet hostile to live due to radiation. Thank you...
Or just mutate us so that we can breathe Martian air (what ever that is) Much easier. Much less cheap. Evolution babe!
I'm not a scientist but this sounds like a bad idea already
Also more impossible
It would take a lot of mutations for us to breathe with CO2. O2 is super important in cellular respiration, which is how we make energy. We would have to turn into plants to survive. Mutating someone isn't easy or reliable. Throwing someone into Mar's atmosphere will kill pretty much any animal right away. Evolution isn't going to occur or even natural selection since everything would die.
You need O2 to oxidize food substances.. CO2 isn't an oxidant.
what I'm wondering is why there hasn't been any large animal that hasn't evolved photosynthesis.
Because comeon, it would be hella useful for an organism to be able to get energy from other organisms AND the sun.
I think this video is awesome
Hey, DNews! How is it likely to shoot a comet to Mars right from the space? If YES, what are the suitable locations and how will astronauts find it. Even if they do that, how will they shoot this comet? Maybe, carrying such a huge comet from earth to space or, diverge an existing comet path.
Please try to answer some of these questions in a separate video, or as this is a very old video. Hence if you could refer to any of the videos answering some or all questions above.

Viewer
all this is moot without a magnetosphere
it has one but its realy weak, to weak
DMT Exactly until we can figure out how to strengthen it any atmosphere we create would be blown away by solar winds.
Why don't evolve ourselves instead of changing Mars? We are what we are now because be evolve and adapt to planet Earth. So Planet Mars belongs to another species.
I don't think dust storms are any trouble, since the water and the Plants may keep the dirt on the ground.
On earth, we only see dust storms in dry areas.
When would we start doing this? How much more exploring the planet as is before we deiced to make it our own?
we can get huge rock in earth and hit it into mars xDDD
+Unique NeXon nope
why??
+knex track fan no but are you?
knex track fan ur reported >=(
If he's real that is.
Much easier to build a robotic human body.
Mankind has always specialized in shaping his surroundings to suit his needs, as opposed to the opposite.
Any adaptations have mostly been temporary, just to survive long enough to shape your surroundings.
I'd rather walk on Mars with lush forests and beautiful beaches, than simply trod around in a red hellscape and desert.
Plus, terraforming planets would make them much more 'ours' :P
SinerAthin Terraforming is cute but not especially practical or necessary. If the intent is to terraform Mars because of the climate problem on Earth, then it would be considerably easier to just "terraform" Earth and keep it habitable. If you can turn an uninhabitable planet into a habitable one, then you can turn a marginally habitable planet into a paradise -- especially if you already live there.
The other problem with terraforming Mars is plain ol' gravity. Mars doesn't have much so it can't hold on to as much atmosphere as Earth. You would need a mix of much denser greenhouse gases to warm the planet sufficiently -- but you can't breathe methane or ethane. The gases you can breathe aren't dense enough to work and the gases that are dense enough are toxic. You can get around a lot of problems with terraforming but you can't get around gravity.
Plus Mars doesn't have a magnetic field... the sun's solar wind would pick apart any atmosphere you placed on the planet, just as it has in the past.
Atheism101 Not necessary, but it is a backup. Not because earth is uninhabitable. We think too far ahead and build backups.
***** Terraforming mars is simply not feasible. It's Too COLD!
Now, if we really think that the future holds dyer consequences for the earth then I'd suggest we start building MASSIVE, city sized spacecraft (the size of those depicted in the movie "independence day". Something we can live on for generations upon generations until we find a suitable habitat.
The closest planet outside our solar system is 4.5 light years distance and it's probably not inhabitable. That planet would take us 20,000 years to reach.
Atheism101
I think the main reason to terraform Mars is to expand our race's living space.
It's better to have mankind spread over multiple planets, so that if something disastrous happens to one of them, mankind will still survive.
Not to mention that we grow by challenging ourselves.
Perhaps Terraforming Mars is impossible, but even still, we are going to learn a lot about planets from merely trying. And if we're lucky, maybe it is possible, and we'll have earned a new green planet.
And knowledge is invaluable and everlasting :)
Kim Stanley Robinson explains how to do it in his book 'Red Mars'. And you don't crash the ice asteroids on mars, you aerobrake them. This generates heat, releases the water, and you don't fuck up the landscape.
so if the atmosphere slowly erodes away then does that mean we would have to keep shooting more ice comets at mars or what?
Under 301 club
Are you new to TH-cam?
***** lmgtfy.com/?q=TH-cam
congratulations are in order
wouldnt venus be easier, some carbon fixing bacteria and that place will cool rather quickly
That is a good idea,but the term "easy" doesnt really apply to what scientists want to do,if we can conquer mars and live on it, it would basically be martians,but alot of racial slurs will come
Venus is like 900 Celsius all the time and has the same pressure of the bottem of the ocean and the air is extremely poisiness.
***** You forgot it often rains acid... Lets make a home there sure!
the sulfuric acid never reaches the ground due to the heat. And apparently is produced in its high quantities because of a reaction beginning with CO2, remove the CO2 and reduce, more importantly, the overall pressure and scary acid rain
Joshua Pittman Someone mentioned hydrogen bombs.
i just love science
you make it sound so easy! lol
Implement sharia law and name mars a satan, throw big stones (comets) on mars!!, boom u have an atmosphere!! congrats.
I think that in some past video you made a video about sending a gigant magnet betwen sun and mars in order to stop the solar winds. You should have included that on the list...
Is there any way to strengthen the Magnetic field?
Would it be possible to create your own ice comets especially since water will freeze in space couldn't we just bring water up and create our own ice comets with whatever elements/minerals we needed to add to get job done
