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.
Dnews: Breaking boundaries by still not actually reporting on news.
still better than FOX news
Just about anything is better than MSNBC
milodudeful a school newspaper is better than FOX news
they do report on science news...doesnt mean thats ALL they can do on the channel.
Fox new's usually lies about things.
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? ^
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.
@AARON IBARRA What if it isn't though?
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
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
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.
Is that Darude - Sandstorm in the background?
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
Question: wouldn't Mars need a moon, or two?
1:38-Mars need an ozone layer, which it does not have
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.
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.
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
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
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.
love your channel! thanks for all the hard work!
"If you were able to stand on Mars as you're dressed right now..." ... the one time I'm not wearing pants XD *facepalm*
Why 360p?

We have cookies
ok for the cookies
because this video came out alittle while a ago so just let it set up
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.
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?
DNews I would like to see more videos on Terraforming, Titan, Luna (our moon) or Venus perhaps.
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 !
in 500 years living on Mars will be normal
Two issues with terraforming that I've not seen a single person address:
Once you've melted all of the polar ice caps...
1) how do you hang on to the atmosphere in the presence of solar wind and no magnetosphere?
2) how much livable landmass would be left with water filling all the dings and dents of the planet?
Water was discovered on Mars in 2015. That's one obstacle out of the way! ☺
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.
I personally hope we terrafrom Venus first and terrafrom mare as we go along. One thing we may have to do to live on Venuses surface is build items that shield the sunlight, alot of the green house gases that make it so hot will freeze and we can then transport the frozen gases to Mars where it is needed to heat it up
Kim Stanley Robinson deals at length with these issues in his series "Red Mars," "Green Mars," and "Blue Mars."
No Thank You Earth Is My Life💙💚
may we meet again
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.
Regards-
Viewer
If they can get some kind of plant to grow on mars, when the atmosphere is able to support it they will be able to have less impact from dust storms
a cup full of nano robots could do it.
Very good presentation by a very good presenter.
Number 2 can be helpfull to contain matirials from mars and make our own space ships there, and then you go to plan 3 which then ur closer to those comets, attach some marsion ships into it, drive them into a place far alway from the factorys and then wait a little, send plants close to the impact, and ta ta ra raaa! We have a new home
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'.
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...
Humans:(silently) Hey kid wanna some icy asteroids?
When would we start doing this? How much more exploring the planet as is before we deiced to make it our own?
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.
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 :)
was there not a scientist a few years ago that published an article on how to terraform mars by introducing a chemical formula other than the ones mentioned in this broadcast. i want to say it was in either the mars underground documentary or the mars documentary with william shatner narrating.
I think it is possible if scientists make a smaller version of mars on earth creating mars like conditions and test for life forms, modifications etc.
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.
They should use Comets, the mirrors, and factories. This will speed up the process. When vegetation is introduced in the right way the dust storm will slowly go away. With this drastic change in climate it will create even higher winds.
Mars does not have any Active Volcanoes left which could ruin any plans we have for Mars. Nutrients can not be returned to the soil by volcanic ash so what ever soil is left on mars, which is actually great for farming believe it or not, could loose all of its nutrients so farming would also be impossible along with planting trees to keep the atmosphere stable. Volcanoes, as destructive as they may seem, are what makes soil possible
By the time Mar's will be terraformed, we will have created Warp drives that take us to other "Earth Like" planets in other solar systems.
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?
Could you explain the physics that would cause our blood to boil if we were on Mars w/o a suit? I don't understand why we would boil?
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 ??
The thick atmosphere and water would prevent violent dust storms.
You would need to seed it with green plants and trees. Sent by drones and planted around the areas thats most likely holds water.....
What this made me think of is how a drastic change of Mars's mass like this would change its orbital path. Terraforming Mars would probably be considered a failure if it collaterally wipes out other planets in our solar system.
Does Nuclear missiles works instead of using a frozen comet which is merely impossible to gather or obtain?
we are going to be living on mars with in my life time, maybe not an earth-like mars but there will be human colonies. that's fucking amazing. im living in a crazy time period and i love it. we'd have to make sure that, the chemical contents of the asteroid is suited for us if it works right?
Gravity seems to be the biggest problem, and our understanding of the theory is so abstract it would be far beyond our reach to adjust the planet's gravity to fit our needs. We would have to augment ourselves someway to be able to withstand the low gravity over a long period of time.
To successfully terraform Mars, one would need to import a moon in order to reactivate the planet's magnetic field. Jupiter's Moon Io might be ideal for Mars as it would allow the terraforming of Mars to be successful. It will take a long time for the technology to develop a magnetic field that can move a moon from one planet to another. It might even be possible to make the planet Mercury as Venus Moon once again.
How do we make Mars spin faster?
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?
I don't get the thing about bacteria contamination, isn't the whole point to be able to live there without a spacesuit and be able to contaminate?
Is Mars's atmosphere even thick enough to hold the greenhouse gasses in?
i don't think so, its about 1% as strong as earths
I love space...Again!
Haven't watched yet but, I am 11 and I, know what terraforming is come one ! :D
Your blood would not boil instantly. While your heart is beating, your blood pressure would keep your blood liquid. Also, your skin is quite strong, and atmospheric pressure on mars is NOT 0. In some places, it is above the triple point of water (although nearly five-and-a-half times below Armstrong's limit.
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?
Venus has better gravity for us than does Mars. It might be easier to begin terraforming Mars, but when the project is finished it still won't be good for our health because we evolved for a specific gravity.
When the color of the photos are corrected to match the color charts, the sky is blue and the ground looks like here on Earth... why is that?
How about huge Fresnel Lenses instead of mirrors? I think that would be cheaper.
What about Mars's core? many scientists believe thats why we have a magnetic field. Mars's core has apparently solidified and thus doesn't have a magnetic field capable of deflecting solar winds, hence why Mars looks the way it does.
what would we use to fuel the green house factories if we were to do so
Even if we put air and such onto Mars, the core of mars is either too cold or not strong enough to support a magnetic field, meaning that all the effort would be for nothing because the air would just be scraped off of mars
I hate how people complain about how it would be too expensive, for something like this it shouldn't matter
Honestly, I hope we don't terraform Mars. It won't be the "red planet" anymore, which I think is more unique if we keep it the way it is. I want people to live on *Mars*, not Earth 2.
Their theory was Mars once had thick atmosphere just like Earth. But due to smaller size with weaker gravity some atmosphere leaks into space but any air lost was replaced by volcanoes emitting gas but when eruption ceased Mars was in trouble. If their theory was correct then any attempt to thicken the Martian atmosphere will end up leaking into space again so it's not possible.
i hope something crazy happens in space in my life time i love this kind of stuff my goal is to become a deep space explorer when we all have flying cars or space ships lol
you could use moss to supply oxygen and send roaches to mars (which would have to adapt to survive the cold temperatures and space radiation). roaches are dark which means they could absorb more sun light, heating up the planet.
You forgot about the biggest problem of Mars: no magnetic field at all! Terraforming itself, making an atmosphere, an breatheable air - this kinds of problem we can solve with our current technology, but making an electromagnetic field to hold the atmosphere and keep the sollar wind out of our bodies is an unreachable problem for us these days.
P.S. sorry for my english;)
What if somehow a catastrophic event happens to both planets, after they're terraformed, and one finally rediscovers space technology, and finds life on mars?
I thought this was going to be one of those none funny short jokes. Like, how do you survive a pool full of crocs? you don't get in the pool. DUR !!!!!
Yeah, Yeah it was done in the movie Total Recall.
2:25 "haha NO" IM DYING HAHA
I think terraforming is amazing!
Great idea! Send a bunch of asteroids and icy comets to Mars to 1) increase it's bulk so it will have more gravity and 2) increase the temperature and increase the volume of water! Brilliant! What if it gets too hot for us to go and plant ourselves on the too hot planet? Increasing the volume/gravity is a must though so we should get going on this right away.
wouldnt i make more sense to dig, or utilize cave systems , or domed environments made from a substance utilizing the materials of mars,( mars silicates = mars glass), and "transforming" the inside of these smaller places? also consider , in regard to contamination. human cells tend to divide differently under irradiated environments and can cause issues with dna. any organism there for long enough periods to reproduce might be irreparably changed on the genetic level, human or otherwise. also could a smaller elecromagetic field produced from a large enough generator be suffecient at diflecting ionizing radiation in place of a suitable core. it wouldnt generate large enough to protect an entire planet, but can one be made to protect a base area?
If Mars had a volcano (or volcanoes) erupting for 2 billion years straight it's kinda obvious why the magnetosphere is dead, too much disruption of the core's processes shut down the magnetic dynamo. Mars essentially bled out.
Trying to live on mars seems like the exact definition of living on the edge.
Half of me is like ( I want to live on Mars ) and the other half is like ( why the fuck are we destroying the only planet we know that is livable for humans )...HUHH!!!!! -_-
What about the magnetosphere?
Mars does not have one, that is why solar winds pick up about 600g of mars atmosphere per second?
Our blood wouldn't boil and our organs wouldn't rupture (except the lungs if you try holding your breath), this wouldn't even happen in near perfect vacuum, as the natural pressure of our blood vessel let's the bo iling point of blood stay at about 43°C. Please check your facts when doing scientific shows.
Whats scary is what people on mars would think in 500 years... They may be thinking "oh hey look we discovered aliens!" if a human space ship lands there or something
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 can we give it plants and stuff?
Martian gravity is too low for human life to safely persist there for anything over 6 months or so
do a vid on mars gravity and how it relates to the human body okplzandthnks!
The question should be, "what if we could go to Mars". And whoever does should bring a video camera that actually works.
Lol but what if there is life on Mars and the comets hit them, what would they think of us?
Bro
animal + environmental change = evolution
I'm so ready to talk about the different human colonies of the future! ( human + mechanical enhancements = at what point is one less human?)
Wouldn't the greenhouse gas solution be inviable? I was under the impression that a too-high concentration of CO2 would be toxic to humans. That's aside from the fact that it still doesn't give us a sufficient source of oxygen, unless combined with one of the other two solutions.
First we create a thick co2 atmosphere to warm the planet and increase atmospheric pressure. That way humans could walk around with nothing more than an auxiliary oxygen supply. Then we would begin creating oxygen. It would be a very long and slow process. To start with, we would be able to harvest some oxygen and nitrogen from the soil. Once we had enough of that to sustain complex plants we could begin planting them. Once they covered the planet we'd wait for them to do their thing. It's predicted with current technologies it would take about 900-1000 years to get to the point where we could breathe the atmosphere. But technology is advancing very quickly and we are learning more and more so who knows how much more efficient we'll be at the process in the next century.

+Sam Nielsen Yeah but what about Mars having such low gravity? That causes people to lose bone density and muscle mass.
+dynelol I'm not sure there is any solution known YET, other than proposals for genetic modification. Basically forcing ourselves to adapt through artificial evolution. But there's not a lot of info about that. Every other solution is based off technologies that don't exist yet however they are theoretically possible. We could never change Mars' gravity unless we increased its mass (maybe by crashing hundreds of huge comets) but I'm sure you can see the inherent issues in this plan. We could however create habitats which have artificial gravity. Again, we're not quite there yet but by the time we start terraforming it's possible we'll have figured it out. And in the meantime? Well, no one actually knows how bad the gravity would be to us. We've only ever dealt with and experimented with either one g or zero g. The partial gravity on Mars would be enough to solve a lot of the issues we encounter in space but we don't know how many issues it might not fix....
+dynelol We've worked around the problem on the ISS somewhat. Results from Scott Kelly's year in space will tell us how well we did. From there the next step would be simulating partial gravity to see what effect it has. It's entirely possible with a bit of daily exercise or a few minutes in a centrifuge we'll be totally fine.
+dynelol keep in mind I'm no expert. I've done a bit of physics and astronomy at uni but that's the extent of my expertise. The rest of what I know is from the Internet haha. So who knows what the experts have cooked up around the world.
