How We Can Live On Mars Without A Spacesuit

[@mr.falcon54]

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.

[@tucker8071]

Agreed

[@grady7682]

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.

Whats the point of Teraforming Mars if it has a weak Magnetic field? You would loose the atmosphere.

[@ItrimUrArmor]

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.

[@mr_byebye]

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

[@20teamplayer]

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.

[@8o8inSquares]

+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..

[@twistedyogert]

+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.

[@20teamplayer]

***** 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.

[@twistedyogert]

We could hit it with something big.

[@20teamplayer]

***** 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.

[@FalconFastest123]

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?

[@ProlificPianist]

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?

[@ReddwarfIV]

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.

[@ericgolightly8450]

​@AARON IBARRA What if it isn't though?

[@Radicus]

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?

[@Lutranereis]

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.

[@Radicus]

Lutranereis Ah. Of course. Thanks for explaining it.

[@Lutranereis]

RaDnWave No problem, I'm quite a buff about terraformation. It's been an interest of mine for a long time.

[@christiancibulka1886]

LOUIS STEFFEN well there is no evidence of NASA faking Apollo so

[@twistedyogert]

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.

[@nano_ranger]

+twistedyogert it would be colder but yeah it could have been

[@brabanthallen]

+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.

+Jim Kang "worlds war 1" lmao

[@mariaisabel-if6zf]

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.

[@Lutranereis]

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.

[@darren93808]

Lutranereis very true was about to say something similar before reading ur comment

[@mariaisabel-if6zf]

Oh, okay.

[@dragofand]

Plants require Nitrogen to grow

[@TheZarkoc]

Because plants filter the atmosphere but there is no atmosphere on mars or at lest not enough to matter.

[@MrLundScience]

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!

[@vargurlord]

+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.

[@GeneralBlackNorway]

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!

Ok, stop - stop...

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.

[@interstellarsurfer]

[@dynelol]

+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.

[@mcguyverworkshop4670]

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.

[@markmuncher3658]

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.

[@mcguyverworkshop4670]

[@janslosn3019]

[@anno636]

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 !

[@HollowEdits]

He said that in the video........

[@maximkazhenkov11]

+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.

[@TruAnRksT]

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.

[@TruAnRksT]

Hey Kate F, don't you have an opinion on any of these things?

[@alecchvirko6578]

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?

[@Lutranereis]

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.

[@RustedCrown11]

Lutranereis well the magnetic sphere is requred to hold an atmosphere.... otherwise the solar winds would just blow it off

[@Lutranereis]

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.

[@coratican]

Lutranereis cool point. i wonder if warming up mars will somehow re-ignite its core?

[@GarudaLegends]

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

"Big" isn't based on its size, but on its importance, in this context - obviously...

[@heartlessgaming2250]

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.

[@pinkponyofprey1965]

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?

[@idtyu]

I think it's easier to terraform Venus

[@qManiekp]

+Yang Junhai So u know nth about Venus.

[@helenatravis5622]

Venus has huge global warming problems. In day it's wayyy to hot and at night wayy to cold

[@biggamer500]

+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'.

[@kevikypenchel9623]

love your vids

[@ReveredDead]

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.

[@nowthatssomegood5hit]

The moon has a minute atmosphere, can it too be terraformed? DNews

[@Lutranereis]

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.

[@nowthatssomegood5hit]

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

[@Lutranereis]

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.

[@FirnenOftheages]

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)

[@Lutranereis]

Firnen Oftheages Mars has two moons, Phobos and Deimos, and the lighter gravity would be problematic, yes.

[@Batinya]

Fastest way to colonize Mars is to drop a custom atomic bomb instead nuke to warm up the planet faster

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.

[@infoharvester]

all this is moot without a magnetosphere

[@god5620]

it has one but its realy weak, to weak

[@MLDprodutions1]

DMT Exactly until we can figure out how to strengthen it any atmosphere we create would be blown away by solar winds.

[@unpopuIaropinion]

Or just mutate us so that we can breathe Martian air (what ever that is) Much easier. Much less cheap. Evolution babe!

[@mannyalt51]

I'm not a scientist but this sounds like a bad idea already

[@Fubbymaster]

Also more impossible

[@MasterSubLink]

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.

[@2fistuppercut663]

You need O2 to oxidize food substances.. CO2 isn't an oxidant.

[@Vaaaaadim]

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.

[@Ramiromasters]

Much easier to build a robotic human body.

[@SinerAthin]

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

[@atheism1019]

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.

[@flowingfireandice]

Atheism101 Not necessary, but it is a backup. Not because earth is uninhabitable. We think too far ahead and build backups.

[@atheism1019]

***** 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.

[@SinerAthin]

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 :)

[@vlad-pm2zr]

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?

[@randale9147]

Humans:(silently) Hey kid wanna some icy asteroids?

[@0011peace]

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.

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?

[@Pitazboras]

1:00 Blood would not boil on Mars, except in open wound. Blood has it's own intrinsic pressure (called blood pressure, duh) which would prevent its boiling point from dropping to much. Any "external" fluid will boil, however, including sweat, tears and the stuff that moisturizes your lungs. Similarly, organs would not rupture. Your body would swell quite a bit.

[@notirishrider7953]

+Piotr Zaborski would your spit not boil ? technically making you get drained of most of your water ?

The saliva inside your mouth would indeed boil. Why would that drain you of most of your water? Saliva is not most of anyone's water, AFAIK.

[@luke6306]

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?

[@iigoofylucyii8103]

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

1:35 - “fix the atmosphere” - What? You’re not “fix[ing]” it, you’re simply manipulating it in such a way that it serves humanity.

[@larryd6143]

Bombarding Mars with nitrogen rich asteroids/comets would be excellent, but we should do some intensive drilling on Mars first to study ice cores and sedimentary layers. The history of Mars is locked away in the ice. Then if we could merge Demos and Phobos in a stable orbit and add a few large asteroids, or put Ceres in orbit around Mars, we could restart Mars internal dynamo and restore its magnetic field while adding stability to the Martian tilt.

[@xDarkAngelxc]

Trying to live on mars seems like the exact definition of living on the edge.

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?

[@devonbarnhart7300]

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?

[@nicholasmitzel8970]

you make it sound so easy! lol

[@stevenmabee3232]

2:15 on your theory #3..could we used the moon Phobos and intentionally smash it into the surface to help heat up the planet and melt trapped water? That Moon is eventually going to be torn apart and rain down on anything we create on Mars, so I think before we send any permeant settlements there we should take care of the Phobos problem. If we don't intentionally drive it into Mars and wait for the fallout to start settling, maybe we could mine it away and use the materials to make the mirrors needed to heat up Mars from orbit..and use it to build on Mars itself by dropping large enough chunks onto Mars's surface from orbit to make it through atmospheric entry but not large enough to do a significant amount of damage.

[@elevenvolt1]

The thick atmosphere and water would prevent violent dust storms.
