I know most of us astronomy lovers know that Mars is not a moonless planet, but I just wanted to clarify for those who do not know that what Raquel meant when she said Mars doesn't have a moon is that it doesn't have a moon like the one planet Earth has. Phobos and Deimos are small and irregular in shape unlike our Moon.

GREAT video! Mars' habitability is a subject well covered on youtube, but this was so well written, presented and edited that it just made for such a fun and educational watch. Raquel Nuno also did a really great job explaining very complex things. Lesser geologists would have a hard time putting this stuff into such understandable sentences :) Thanks!
I've heard it said that a sign of true intelligence is the ability to explain complex subjects in a way that even a small child can understand. This is because it shows a deep understanding of the topic. It's also a wise thing to do.
@@AwwwThatsMintocs Yes, that has also been my experience in life. There is something to be said for pedagogical skill as well, but people who don't turoughly understand a subject don't tend to be capable of explaining it in a simple, easy to understand way no matter how good a teacher they are. And there are people who are very good at what they do and obviously have a deep understanding of the field they are working with but struggle to explain the simplest aspect of it. There are many factors involved, for sure. But as a quick and quotable generalization i think you statement rings true :) Nuno, and Dianna herself, appear to be have all of these qualities. Which is a rare thing, in my expereience.

We need more videos like this, I research Mars more than the average astronomy nerd but I still didn't know the tilt thing, all I knew was that it was less stable due to the lack of a big moon, never the Juputer thing
I think she was inferring that our moon has a much more significant role in our orbit than Mar's tiny(non-consequential) moons, I in fact, many scientist think of the our Earth-Moon system as a "dual planet" because are moon is so large (in comparison to the Earth), and has such a large stabilizing effect on the Terran rotation and orbit.
@@pastresmalin34 Definitely. I mean, it's the size of a Ganymedan moon ffs, and Earth ain't Jupiter. Besides, I really think we need a new word for captured asteroids to differentiate them from natural spherical moons like we have one for "dwarf planets". Maybe "dwarf moons", or "asteroidal satellites"? Lol there's probably much better names, but an Europa, Ganymede, Enceladus or Titan which have atmosphere (the last one even thicker than Earth's...) and may even harbour life are something completely different from Phobos or the 70-something rocks orbiting Jupiter besides the 4 Ganymedan giants...
The comment around 9:00 about the wind being "meh", even though it's fast but only a fraction as dense as we're used to makes me wonder: what would such a "fast" but extremely low pressure wind even feel like?
I was reading that Mars lacks the electromagnetism that earth has that I'm sure affects its tilt as well as the ability to repel certain amounts of radiation (which was the focus of the article I was reading). I love that they are now flying a drone on Mars, albeit only at 16 feet high.
This girl have the looks, have the talk ...she can play a scientist in a Hollywood si-fi movie. Or since having the looks she can play a monster in the TV series From
@@georgearnold841 I'm seeing many articles where the wording about the radiation levels just say something like, "the surface of Mars is exposed to much higher levels of radiation than Earth" to which I infer that the thin atmosphere does offer some protection, even in the absence of a magnetic field and then there is differentiating how much radiation is repelled by electromagnetic fields alone. I'm reading up on the Mars Odyssey mission and results. I have no background in this area and was not speaking as an authority in any sense.
@@seaninness334 the 1% as thick atmosphere doesn’t do much for radiation protection as you are thinking. Mars’ essentially gets hit with the same amount of radiation as earth, just minus the diffusing effect from orbiting a bit further out. It’s a very dangerous amount. The “higher amounts than earth” description is just a short and simple way for journalists to relate the added danger, without going into technical terms most readers would have no reference for. Also, they don’t want to get into the widely varying levels, and possibly killing peoples dreams for manned Mars exploration & later colonization. Imagine writing an article about Curiosity or Elon’s plan for a colonization, and telling people a solar storm could mean the astronauts aren’t not coming home. The Elon Fanboys especially would be arguing against scientific fact with “he’s going to make an artificial magnetosphere before we go there.” (Something I’ve seen happen on other videos about Mars)
@@cjwrench07 I agree that the hype glosses over the blunt facts and that's what I'm trying to get at. Most of the articles in the popular media that I was reading became oddly vague in their descriptions. It's like the meme, "Your chances of being murdered by a cow are extremely low, but it's never 100% unlikely". I've worked mostly in the entertainment industry and films like The Martian (or Andy Weir's novels in general) make it seem possible with only a dash of actual science related to issues of survival and travel. So I would prefer the blunt data, even if it is simplified for us outsiders. George Arnold was just a tad condescending above. Anyway, I appreciate your POV and... all hail Cthulu, hehe
Even with minor winds, tiny rough edged lung damaging dust would get inside any vehicle. I think even the lunar astronauts had some problems with that, and they didn't go back and forth mutliple times a day for months like hypothetical Martians ones would.
@@TheCimbrianBull It has loads of perchlorates. In very tiny doses it can blow out the thyroid and eventually damage the lungs. So it's a real danger that needs to be addressed before any manned mission takes place.
What I love most about this video? In the background there are books, and books, and books, and books, aaaaaaaaaaannnnnddddd BOOM! OREOS! Well played Raquel, well played.
I'm shocked that the prevalence of perchlorates in the Martian soil wasn't one of the first points made. These are kinds of salts that interfere with normal human thyroid operation, and which would make you very sick, very quickly. It would be almost impossible to avoid perchlorates in the blowing dust, which would surely get lodged in every environmental seal - like, on spacesuits, and on spacecraft & building entrances. Instead she characterizes Martian dust storms as being like a gentle breeze... sheesh.
@@lordfraybin Ha! There are no dangers too gruesome to discourage _some_ (many!) would-be Mars colonizers. Their zeal is apostolic. After all, they intend to supply humankind with a backup plan, for when we've f#@%ed up our own planet so badly we decide to abandon ship. Try convincing them that Mars comes _pre_ f#@%ed up - conditions much worse than humans could _ever_ recreate on Earth.
No potatoes would not grow on Mars as it is as the soil lacks all the elements and nutrients that plants need to grow Even the atmosphere doesn't contain enough co2 although the thin atmosphere on mars is mostly co2 with some methane and even a small amount of oxygen This thin atmosphere doesn't hold onto any liquid water either If man tried to settle there then only a green house would possibly work and adding the nutrients and elements needed for plants to grow to the soil
Mars actually has a blue sky and the ground is not red all over. The ground is a set of different colors. Plants and ancient structures have also been found on Mars.
@Kaegri Yepp, she's adorable but that image was not of crashed Mars probe. But to be fair, we don't have really good images of any of the crashed ones so I guess the heat shield was the closest approximation.
Awesome summary. Thanks Physics girl. When I studied physics in the 70s there were no physics girls, only physics bros, and very few geology girls either. You did a great job making the environment on Mars understandable for the youtube audience. Keep up the great work.
This girl have the looks, have the talk ...she can play a scientist in a Hollywood si-fi movie. Or since having the looks she can play a monster in the TV series From
There are solutions for that. See futurist Isaac Arthur's YT channel. He is awesome. One of the easiest solutions we could do with today's technology is an array of magnetic satellites, made to sit in the Lagrange point between Mars and the sun. These could also function as solar concentrators, with the ability to direct concentrated light, or microwaves for power. But we will be there under domes centuries before we have the ability to thicken Mars' atmosphere enough for comfortable breathing, plus there's the fact that the dust on Mars is like some.of our volcanoe's plumes: essentially, tiny shards of glass, with a huge amount of it being salts. It will take a very long time to get that to become anything close to terrestrial soil.
Only in Long Term, yes, if we made an atmosphere on Mars in the next 100 years, it would slowly drain over the next 10.000 to 100.000 years. So it's not at all a permanent solution. - But you got time to solve it.
@@Asfaril ... If it only takes a few hundred years to create a suitable atmosphere which then leaks out over 10000+ years then there would be no problem just topping up the atmosphere a little every 500 years or so. Or just continuously trickle charge it.
What about the 1/3rd gravity? It's my understanding that astronauts start losing muscle mass as soon as they reach the space station. Does the reduced gravity on Mars cause a similar harm? Theoretically, you may be able to build an atmosphere for the planet, but you can't adjust the gravity...
I'd love to visit other celestial objects, but haven't learned of any where I'd like to live. Earth is a "goldilocks" planet in so many ways, so I think will remain the preferred place to live long term, even if we colonize elsewhere. Terraforming another planet would great work, though, and would definitely motivate me to live there.
20 years ago I watched a show with my grandmother re: possibilities of colonizing Mars. Her only comment was, "Why would anyone want to live THERE?" lol, good point.
Diana, thank you for not only your programs but also, and more importantly for myself, for inspiring girls and young women to enter the sciences. It's so sad to me that girls haven't been hugely encouraged to do so. Young women need to be shown that they shouldn't listen to others' negative influences and go "reach for the stars". We all should be our best us! Thank you.
She is also an inspiration for boys. Inspiring people are inspiring people. Waaaaay more inspiring that monotone humorless white haired old men in labcoats which is the stereotype.
Tis a pity more women do not see 'the best them' as being at home raising their family anymore! The 'best them' is about ego....and not about the future!
I love how you talked about the magnetic field (or lack thereof). I have always wondered if attempts to terraform Mars would fail because the solar radiation would just wipe any significant atmosphere away without such a magnetic field protecting the planet.
Yes it would. In addition Mars doesn’t have a liquid metal core, so it doesn’t have plate tectonics, so it can’t have a carbon cycle to consume excess carbon in the way that it occurs here.
In "The Martian" Matt Damon doesn´t talk about it, I think.... But, maybe wouldn´t be so difficult to remove or transform those compunds into something merryer.

Sure they do. You can never know how your face looks like if mirrors weren't invented, neither you can know how your planet looks like if right tools weren't invented.
Raquel forgot to mention perchlorate salts in the soil. That fact might make for an interesting episode all by it self. Sorry "The Martian", no potatoes for you!

@@phs125 It was a facetious remark (if not obvious); however, I wouldn't mind to see it get traction or anyone willing to help TH-cam out in that area. Still and to the main point, I like her videos and really would like her to do a title on Venus. Perhaps you, as her spokesperson, could make it happen? :)
If I recall correctly oddly enough Venus due to having a fairly stable climate it might be able to support life on upper atmosphere. Or sth like that. There is no water there but the temperature and pressure is stable so yeah I.might remember totally wrong though so don't quote me look it up.
Paradoxically, Venus is both one of the most hostile places and the least hostile place after Earth. The surface of Venus is a death trap with 92 bars of atmospheric pressure and temperatures that would make an oven look like a freezer! 840 degree weather, anyone? Even machines can't handle Venus's surface conditions! By contrast, the layer just above Venus clouds, roughly 50km up, gets close to being habitable. You'd need an oxygen mask and heat suit at that altitude, but temperatures and pressures at 50km above the Venusian surface aren't that different from Earth. In fact, cloud colonies could be hung from giant blimps or balloons and people could live just above the Venusian clouds.
I was asking myself the same question. Is it a picture of her boyfriend or other relatives? Probably not: the blurred image shape&color look very luch like the Hogwarts picture.
I really like this because you touched on things I knew that would be a major issue (the EM field is the huge thing for me because without that, its just not feasible especially if you want to terraform it) but I didn't know about the extreme wobble of it, that was really cool and would absolutely make problems for it, and I didn't even think about how unviable solar would be for Mars.
This girl have the looks, have the talk ...she can play a scientist in a Hollywood si-fi movie. Or since having the looks she can play a monster in the TV series From
So, to 'terraform' Mars, we'd first need to bring a wobble-stabilising moon into its orbit, insert a hot (mostly) iron core surrounded by a molten shell, increase its current atmosphere by at least a 100 times, making sure it has an ozone layer and a composition of about 78% nitrogen and 21% oxygen. Then we'd wait to see whether the water amounts will increase on their own, how the climate develops and perhaps even martian life starts to form. That guy who could do all that in six days is never around when you need him, is he?
Well, an artificial magnetosphere is almost possible. It's just a big solar powered electromagnet stationed at the Sun-Mars L1 point. Doing this would keep the solar wind from stripping the atmosphere away from Mars and internal outgassing would improve the situation. Exactly how _much_ it would improve is up for debate.
I ahve always wondered why scientists believe the core is made of iron nickle alloy other metals as well. When we know for fact gravity( what ever it may be Higgs, muons, all that other boring quantum stuff (jk)) is partial and it prefers to "pull harder on metals such as lead gold. Tell me why It is theorized as it currently is please and thanks. I do.not believe we know even a tiny fraction of what we "call fact or treat as fact in majority cases. Dna on a quantum level as a quick example. Science believed majority of dna was junk. We just recently proved muons exist but Still don't understand gravity a fundamental of life since creation. Yet we understand the repercussions good or bad of altering the building blocks of people...I'm not buying it.
@@cavelvlan25 i think i can answer your question actually but a couple of notes: first, gravity pulls on everything equally and secondly, higgs bosons and muons are particles derived from ideas in quantum theory not relativity, which are **very** different fields of study. you cant say anything about the effects of gravity on things so small. to answer your original question. as far as i know, astronomers figure out the composition of planets by a using a combination of observation and some educated guessing. tracking the movement of something they put in orbit of the planet gives ideas of the densities of each layer (even the core). another way is tracking the earthquakes on the surface, we give similar indicators. i learned in my physics class (i'm a high school senior btw) that some scientists do something called spectroscopy, which uses light to decipher the chemical composition of planets and stars, which i think is cool. so yeah that's how they know
@@pola_behr Your answer shows they/you actually don't have the answer . Particle physicist do claim that gravity effects some particles differently than others. It either doesnt pull on everything equally or some things are immune to gravity. Relativity and quantum mechanics are as different as they are similiar as everything is relevant. Speculation no matter how informed is just thay Speculation. A for effort yet none of this is fact.

@@Paul_Wetor on the 1 atmosphere range. Not that hot and without the problem of the different pressure. And with the possibility of having "garden airships" to lower the CO2 in the atmosphere. Those 847ºF are on the surface... with 60 atmopheres.
@ that 1 atmosphere range is also an acid bath, which makes those balloons have some problematic concerns. Add in that vulcanism isn't certain with Venus, so an acid injection into the upper atmosphere is also a possibility. I'd recommend research stations in orbit and maybe at the cloud top level for a few generations, just to be sure. Mars, just go a couple of meters below the regolith surface and you'll be OK for most radiation. We've gotten pretty good at maintaining an atmosphere in orbit, so it should be a trifle easier under the surface of Mars. Gravity would be a problem, so I'd not recommend longer than a year at most there and that'd be pushing it by double what we've tested thus far.
Trapped asteroids as I have heard from space and astronomy episodes on Mars. One of them, don't remember which, is in a colision route with the surface of the planet itself, a colision which will take time though.
@@F1aficionado Well you are not wrong, but still mars moons are probably traped asteroids and will colide much sooner than "everything in the universe"
Yes, Mars has two moons, but they are far too small relative to the planet to stabilize its axis of rotation. Phobos is only about 25 km long, and Deimos is about 15 km long. For comparison, the Moon's diameter is about 27% of Earth's diameter.
We should deorbit Deimos and Phobos into the poles of Mars and then insert Ceres into a stable orbit around the planet. That is if humans should ever attempt to geoengineer it.

However, it is not used in that context typically, but rather, to highlight the finishing of your explanation why something happens. It was often used in a scientific context wrapping up a theory of why something is the way it is.
@@eilong Probably because of the surface-to-volume ratio. Mars is much smaller, compared to the Earth, so loses heat more rapidly. Also it probably lacks certain radioactive elements that contribute to the heat inside the Earth.

Also, one reason it's easier to get a job on Mars is because there's less pressure.

@@AwwwThatsMintocs Yes, that has also been my experience in life. There is something to be said for pedagogical skill as well, but people who don't turoughly understand a subject don't tend to be capable of explaining it in a simple, easy to understand way no matter how good a teacher they are. And there are people who are very good at what they do and obviously have a deep understanding of the field they are working with but struggle to explain the simplest aspect of it. There are many factors involved, for sure. But as a quick and quotable generalization i think you statement rings true :)

We need more videos like this, I research Mars more than the average astronomy nerd but I still didn't know the tilt thing, all I knew was that it was less stable due to the lack of a big moon, never the Juputer thing
4:30 Mars does have a moon; in fact, it has two, Phobos and Deimos. It's just that Mar's moons are smaller than ours,
It's wild how important our moon is and how atypically big it is. Earth is super special.
I think she was inferring that our moon has a much more significant role in our orbit than Mar's tiny(non-consequential) moons, I in fact, many scientist think of the our Earth-Moon system as a "dual planet" because are moon is so large (in comparison to the Earth), and has such a large stabilizing effect on the Terran rotation and orbit.
@@pastresmalin34 Definitely. I mean, it's the size of a Ganymedan moon ffs, and Earth ain't Jupiter. Besides, I really think we need a new word for captured asteroids to differentiate them from natural spherical moons like we have one for "dwarf planets". Maybe "dwarf moons", or "asteroidal satellites"? Lol there's probably much better names, but an Europa, Ganymede, Enceladus or Titan which have atmosphere (the last one even thicker than Earth's...) and may even harbour life are something completely different from Phobos or the 70-something rocks orbiting Jupiter besides the 4 Ganymedan giants...

Size DOES matter
The comment around 9:00 about the wind being "meh", even though it's fast but only a fraction as dense as we're used to makes me wonder:
what would such a "fast" but extremely low pressure wind even feel like?
I was reading that Mars lacks the electromagnetism that earth has that I'm sure affects its tilt as well as the ability to repel certain amounts of radiation (which was the focus of the article I was reading). I love that they are now flying a drone on Mars, albeit only at 16 feet high.
This girl have the looks, have the talk ...she can play a scientist in a Hollywood si-fi movie.
Or since having the looks she can play a monster in the TV series From
Certain amounts of radiation? Try that it repels ZERO amounts of radiation.
@@georgearnold841 I'm seeing many articles where the wording about the radiation levels just say something like, "the surface of Mars is exposed to much higher levels of radiation than Earth" to which I infer that the thin atmosphere does offer some protection, even in the absence of a magnetic field and then there is differentiating how much radiation is repelled by electromagnetic fields alone. I'm reading up on the Mars Odyssey mission and results. I have no background in this area and was not speaking as an authority in any sense.
@@seaninness334 the 1% as thick atmosphere doesn’t do much for radiation protection as you are thinking. Mars’ essentially gets hit with the same amount of radiation as earth, just minus the diffusing effect from orbiting a bit further out. It’s a very dangerous amount.
The “higher amounts than earth” description is just a short and simple way for journalists to relate the added danger, without going into technical terms most readers would have no reference for.
Also, they don’t want to get into the widely varying levels, and possibly killing peoples dreams for manned Mars exploration & later colonization. Imagine writing an article about Curiosity or Elon’s plan for a colonization, and telling people a solar storm could mean the astronauts aren’t not coming home. The Elon Fanboys especially would be arguing against scientific fact with “he’s going to make an artificial magnetosphere before we go there.” (Something I’ve seen happen on other videos about Mars)
@@cjwrench07 I agree that the hype glosses over the blunt facts and that's what I'm trying to get at. Most of the articles in the popular media that I was reading became oddly vague in their descriptions. It's like the meme, "Your chances of being murdered by a cow are extremely low, but it's never 100% unlikely". I've worked mostly in the entertainment industry and films like The Martian (or Andy Weir's novels in general) make it seem possible with only a dash of actual science related to issues of survival and travel. So I would prefer the blunt data, even if it is simplified for us outsiders. George Arnold was just a tad condescending above. Anyway, I appreciate your POV and... all hail Cthulu, hehe
What about the poisonous salts? And the extremely fine dust?
Even with minor winds, tiny rough edged lung damaging dust would get inside any vehicle. I think even the lunar astronauts had some problems with that, and they didn't go back and forth mutliple times a day for months like hypothetical Martians ones would.
Mars is salty af?
@@TheCimbrianBull It has loads of perchlorates. In very tiny doses it can blow out the thyroid and eventually damage the lungs. So it's a real danger that needs to be addressed before any manned mission takes place.
just don't eat the salts or the dust

What I love most about this video? In the background there are books, and books, and books, and books, aaaaaaaaaaannnnnddddd BOOM! OREOS! Well played Raquel, well played.
I'm shocked that the prevalence of perchlorates in the Martian soil wasn't one of the first points made. These are kinds of salts that interfere with normal human thyroid operation, and which would make you very sick, very quickly. It would be almost impossible to avoid perchlorates in the blowing dust, which would surely get lodged in every environmental seal - like, on spacesuits, and on spacecraft & building entrances. Instead she characterizes Martian dust storms as being like a gentle breeze... sheesh.

My biggest one is the lack of a magnetic field. It can never have an atmosphere without one. May as well be vacuum.
There are solutions for that. See futurist Isaac Arthur's YT channel. He is awesome. One of the easiest solutions we could do with today's technology is an array of magnetic satellites, made to sit in the Lagrange point between Mars and the sun. These could also function as solar concentrators, with the ability to direct concentrated light, or microwaves for power. But we will be there under domes centuries before we have the ability to thicken Mars' atmosphere enough for comfortable breathing, plus there's the fact that the dust on Mars is like some.of our volcanoe's plumes: essentially, tiny shards of glass, with a huge amount of it being salts. It will take a very long time to get that to become anything close to terrestrial soil.
Only in Long Term, yes, if we made an atmosphere on Mars in the next 100 years, it would slowly drain over the next 10.000 to 100.000 years. So it's not at all a permanent solution. - But you got time to solve it.
yah. seems bad.
@@Asfaril ... If it only takes a few hundred years to create a suitable atmosphere which then leaks out over 10000+ years then there would be no problem just topping up the atmosphere a little every 500 years or so. Or just continuously trickle charge it.
What about the 1/3rd gravity? It's my understanding that astronauts start losing muscle mass as soon as they reach the space station. Does the reduced gravity on Mars cause a similar harm? Theoretically, you may be able to build an atmosphere for the planet, but you can't adjust the gravity...
hinc illae lacrimae: "that is what those tears were for" In case anyone was wondering
I'd love to visit other celestial objects, but haven't learned of any where I'd like to live. Earth is a "goldilocks" planet in so many ways, so I think will remain the preferred place to live long term, even if we colonize elsewhere. Terraforming another planet would great work, though, and would definitely motivate me to live there.

I love how you talked about the magnetic field (or lack thereof). I have always wondered if attempts to terraform Mars would fail because the solar radiation would just wipe any significant atmosphere away without such a magnetic field protecting the planet.
You got it right on the first try.... too many people fail to realize this super important fact in the colonization of the planet.
Magnetosphere
Yes it would. In addition Mars doesn’t have a liquid metal core, so it doesn’t have plate tectonics, so it can’t have a carbon cycle to consume excess carbon in the way that it occurs here.

At least its warm there and it has a thicc atmosphere
If I recall correctly oddly enough Venus due to having a fairly stable climate it might be able to support life on upper atmosphere. Or sth like that. There is no water there but the temperature and pressure is stable so yeah
I.might remember totally wrong though so don't quote me look it up.
Paradoxically, Venus is both one of the most hostile places and the least hostile place after Earth.
The surface of Venus is a death trap with 92 bars of atmospheric pressure and temperatures that would make an oven look like a freezer! 840 degree weather, anyone? Even machines can't handle Venus's surface conditions!
By contrast, the layer just above Venus clouds, roughly 50km up, gets close to being habitable. You'd need an oxygen mask and heat suit at that altitude, but temperatures and pressures at 50km above the Venusian surface aren't that different from Earth. In fact, cloud colonies could be hung from giant blimps or balloons and people could live just above the Venusian clouds.

soooo, why did you feel the need to blur out the Hogwarts poster in one part of the video but not in another? :p
My guess is since the blur was during a lego ad, lego didnt want any copy write issues or overlap between product lines
🤔 How do you know that the Hogwarts poster was not covering the actual image that was previously blurred out?
TH-cam have turned into Australian TV: No nudity, every logo blurred and comedy amounts to saying the word "bum" in a funny voice!
@@erikig simple, the colors and the gross shape matches with the unblurred image.
I was asking myself the same question. Is it a picture of her boyfriend or other relatives? Probably not: the blurred image shape&color look very luch like the Hogwarts picture.
Why people think it's a good idea to colonize Mars is beyond me
I really like this because you touched on things I knew that would be a major issue (the EM field is the huge thing for me because without that, its just not feasible especially if you want to terraform it) but I didn't know about the extreme wobble of it, that was really cool and would absolutely make problems for it, and I didn't even think about how unviable solar would be for Mars.
This girl have the looks, have the talk ...she can play a scientist in a Hollywood si-fi movie.

Whoops! You forgot to blur out Hogwarts @ 10:30 like you did at 10:08 :)
Probably blurred because it was during a sponsor soot... or maybe they just missed it. Who knows
Glad the TH-cam Algorithm showed me your video! Great stuff
So, to 'terraform' Mars, we'd first need to bring a wobble-stabilising moon into its orbit, insert a hot (mostly) iron core surrounded by a molten shell, increase its current atmosphere by at least a 100 times, making sure it has an ozone layer and a composition of about 78% nitrogen and 21% oxygen.
Then we'd wait to see whether the water amounts will increase on their own, how the climate develops and perhaps even martian life starts to form.
That guy who could do all that in six days is never around when you need him, is he?
Well, an artificial magnetosphere is almost possible. It's just a big solar powered electromagnet stationed at the Sun-Mars L1 point. Doing this would keep the solar wind from stripping the atmosphere away from Mars and internal outgassing would improve the situation. Exactly how _much_ it would improve is up for debate.
I ahve always wondered why scientists believe the core is made of iron nickle alloy other metals as well. When we know for fact gravity( what ever it may be Higgs, muons, all that other boring quantum stuff (jk)) is partial and it prefers to "pull harder on metals such as lead gold. Tell me why It is theorized as it currently is please and thanks. I do.not believe we know even a tiny fraction of what we "call fact or treat as fact in majority cases. Dna on a quantum level as a quick example. Science believed majority of dna was junk. We just recently proved muons exist but Still don't understand gravity a fundamental of life since creation. Yet we understand the repercussions good or bad of altering the building blocks of people...I'm not buying it.
@@cavelvlan25 i think i can answer your question actually
but a couple of notes:
first, gravity pulls on everything equally
and secondly, higgs bosons and muons are particles derived from ideas in quantum theory not relativity, which are **very** different fields of study. you cant say anything about the effects of gravity on things so small.
to answer your original question. as far as i know, astronomers figure out the composition of planets by a using a combination of observation and some educated guessing.
tracking the movement of something they put in orbit of the planet gives ideas of the densities of each layer (even the core). another way is tracking the earthquakes on the surface, we give similar indicators.
i learned in my physics class (i'm a high school senior btw) that some scientists do something called spectroscopy, which uses light to decipher the chemical composition of planets and stars, which i think is cool.
so yeah that's how they know
@@pola_behr Your answer shows they/you actually don't have the answer . Particle physicist do claim that gravity effects some particles differently than others. It either doesnt pull on everything equally or some things are immune to gravity. Relativity and quantum mechanics are as different as they are similiar as everything is relevant. Speculation no matter how informed is just thay Speculation. A for effort yet none of this is fact.
@@pola_behr does it not make sense to you that the most dense materials the heavies would make up the inner core of earth

I heard of the possibility of living on the clout tops of Venus. Similar size to earth, similar gravity. A much slower rotation and no satellite, but Venus doesn’t seem to be getting more attention than it should in this regard. Could you do a video on that?
Your right about that, but Mars only has all that clout because it has an editor.
Maybe we could edit Venus?
The average surface temperature of Venus is 847 degrees Fahrenheit. Cloud tops? You might as well be living in space.
@@Paul_Wetor on the 1 atmosphere range. Not that hot and without the problem of the different pressure. And with the possibility of having "garden airships" to lower the CO2 in the atmosphere.
Those 847ºF are on the surface... with 60 atmopheres.
@ that 1 atmosphere range is also an acid bath, which makes those balloons have some problematic concerns.
Add in that vulcanism isn't certain with Venus, so an acid injection into the upper atmosphere is also a possibility. I'd recommend research stations in orbit and maybe at the cloud top level for a few generations, just to be sure.
Mars, just go a couple of meters below the regolith surface and you'll be OK for most radiation. We've gotten pretty good at maintaining an atmosphere in orbit, so it should be a trifle easier under the surface of Mars. Gravity would be a problem, so I'd not recommend longer than a year at most there and that'd be pushing it by double what we've tested thus far.
@@Paul_Wetor and the pressure is crazy it'll be easier to live in a oven
Two brilliant & gorgeous minds. Great content!

At 4:35, she says Mars doesn't have a moon to help stabilize it. But...Mars has TWO moons! What about them? Are they not big enough to matter?
Mars doesn't have moon? What are Deimos and Phobos then?
Two pieces of rubble.
Moons but so small as to have little effect on Mars.
Bite-sized moon-ettes.
Trapped asteroids as I have heard from space and astronomy episodes on Mars. One of them, don't remember which, is in a colision route with the surface of the planet itself, a colision which will take time though.
@@F1aficionado Well you are not wrong, but still mars moons are probably traped asteroids and will colide much sooner than "everything in the universe"
4:30 That tattoo on her arm means "that is what those tears were for"
I think it says, "hinc illae lacrimae" [Latin for: hence these tears]
She might be crying cause she does not have someone to hold at night but I do not know...
@@johnhernandez9338 - She's married to Derek Muller aka Veritasium.
@@beteljooz6180 Then I guess she has no reason to cry except for the fact that now she is trapped in her relationship...
@@johnhernandez9338 - That's a very sad and cynical way to look at things.
So... Moons of mars Deimos and Phobos. No discussion of perchlorate salts, which makes soil toxic to plant life.
Yes, Mars has two moons, but they are far too small relative to the planet to stabilize its axis of rotation. Phobos is only about 25 km long, and Deimos is about 15 km long. For comparison, the Moon's diameter is about 27% of Earth's diameter.
We should deorbit Deimos and Phobos into the poles of Mars and then insert Ceres into a stable orbit around the planet. That is if humans should ever attempt to geoengineer it.
@@briand8090 And in the process destabilise all the asteroids in the area (inevitable when you shift so much mass) that will then rain havoc on mars and earth...
@@KimonFrousios The asteroid belt is sparce and a lot less dense than imagined. It should be fine. Not to mention that if this option was doable, those calculations could be done to determine actual risk and not perceived.
Columbus did not fall off the edge.
@@briand8090 If we had the technical prowess and resources it would take shift planetoids around the solar system like you're describing (simply scaling up conventional propulsion technologies is not going to cut it), surely we could just develop a solution that would stabilize Mars's rotation directly?
There's a prominent, light-blue, starlike image you can see in the morning sky on Mars. Life forms *actually live* on that bluish dot.
04:27 Hinc illae lacrimae
Probably a common case of heartbroken planetary geologist... :/
I learned a new latin phrase today. Nunc Ille est magicus
Hinc illae lacrimae, idiom used to indicated that the actual cause for an action or an event has been detected. Since she’s a scientist that’s an adequate motivational quote!
@@bertinii Well, detected especially if a lower motive for action can be identified instead of an initially assumed higher motive.
The idiom does not contain tears casually, and she probably had a psychological reason when selecting it.
I'm in love
'Therefore, the tears' is an idiom. Literally referring to wrapping up the explanation of why you are heartbroken. However, it is not used in that context typically, but rather, to highlight the finishing of your explanation why something happens. It was often used in a scientific context wrapping up a theory of why something is the way it is.
Mars has two moons, Phobos and Deimos...guess they're too small to stabilize the planet?
the are useless . more like astoroids , will hit back mars in few million years .
also is mars having no substantial moon the reason for its more rapid cooling? you know... no tidal forces to keep the mantle liquid
@@eilong Probably because of the surface-to-volume ratio. Mars is much smaller, compared to the Earth, so loses heat more rapidly. Also it probably lacks certain radioactive elements that contribute to the heat inside the Earth.
@@eilong Easy to see how the larger moon would disrupt the crust, keeping it unstable...and this also creates internal heat? Interesting.
Richard Alexander yeah in fantasy land CGI Island. the Earth is flat!!
On Mars there's no pressure? Okay that clinches it, I need to go there.
It's a one way trip. No pressure, dude.
Landing craft crashes on Mars....head designer in the control room when this is found out...oopsie. my bad. See. What happened was...ok..I'll clear out my desk.
Diana: “You’re probably on planet earth watching Physics Girl” Me: “Omg! How’d she know??”
My hypothesis is Mars is *an ENRAGED videogamer*
When it loses it just starts to tilt.
My prediction is huge quantities of salt are hiding under the surface as well.
Finally, a theory i can get behind.
@@RomaineChutckhan why the salty comment?
Geologist: mars is inhabitable
Engineer: hold my beer and video game
Mars' biggest problem is that its small and lacks the mass to retain an atmosphere.
Even if you fix all the other stuff, making it heavier would be a challenge.
I'm sure it's large enough where it would take millions of years to lose its atmosphere or at the least thousands of years. Why not just replenish it?
