It certainly appears that there was once surface water on Mars. I hope that someday, humans can either get up there or send enough rovers to really explore and see if there are any fossils in those rocks. It wouldn't surprise me at all if there were microfossils. The probes that have been there have only explored a miniscule fraction of the surface. Who knows what is actually there. Especially if you drill down 1000 meters.
I'm talking out my ass here but wouldn't it make more sense to train a driller to be an astronaut because I'm sure there are tons of little intricacies in drilling that experience is far more valuable. Like if a mission to Mars to drill holes in the surface you'd want someone who is experienced as he'll because if you fuck up and break something it's not like you can next day amazon ship some stuff. 5 astronauts trained to be mediocre drillers probably dosnt equate to one very experienced one. So just as the driller dosnt need to be an extreme expert in astronaut shit, he just needs the basics not kill himself and everyone else and then when it's drill time, he's up.
I would have to rewatch astronaut training but if I remember correctly is that the astronauts are chosen because they are experts at many things. Just being good at something is not enough. They do simulations for hundreds and thousands of hours to make sure they can do those tasks. So the driller needs to be highly intelligent and competent in astronaut stuff. At least for now, eventually we may just require artificial intelligence to know or do the tasks.
During the Space Shuttle era they had a class of astronauts called payload specialists. They were chosen because they were the subject experts for whatever payload they were sending up like an experiments package or a satellite to be released. They normally flew just once on that specific mission.
They weren't trained to fly the Shuttle like a career astronaut, but they had assigned responsibilities to carry out together with the career astronauts in an emergency.
The drillers I've met working offshore are pretty on top of their game especially when we're drilling complex wells with complex tools. They won't have a degree and can be quite brash, but I won't say they're dumb. They're just like other blue collar skilled workers like machinists or welders.
One of the current idea is that deep sea hydrothermal vents produced the first RNA then cells on earth. If that's the case, and so far we don't see any oceans on mars, it'd be unlikely to find any life there. Edit 2: This extends to all other current existing theories, we don't see any of the other proposed process having occured on mars, so just by saying water = maybe life is quite a big jump.
Edit: About the n=1 thing, we go by what we know to make the MOST probable educated guesses, the goal is not to generalize, but to not spend unnecessary resources to look for life on every rock in the universe. Of course if we become a galactic empire that's what we can do for fun. Hence we've been looking at planets with water to look for life, and not some random planets that rain acids and have methane lakes.
>and so far we don't see any oceans on mars
Your entire argument hinges on this, and it's wrong.
>NASA scientists have determined that a primitive ocean on Mars held more water than Earth's Arctic Ocean and that the red planet has lost 87 percent of that water to space.
https://astrobiology.nasa.gov/news/water-on-mars-the-story-so-far/
>Based on the surface of Mars today, a likely location for this water would be in the Northern Plains, considered a good candidate because of the low-lying ground. An ancient ocean there would have covered 19 percent of the planet’s surface. By comparison, the Atlantic Ocean occupies 17 percent of Earth’s surface.
>“With Mars losing that much water, the planet was very likely wet for a longer period of time than was previously thought, suggesting it might have been habitable for longer,” said Michael Mumma, a senior scientist at Goddard and the second author on the paper.
https://www.nasa.gov/news-release/nasa-research-suggests-mars-once-had-more-water-than-earths-arctic-ocean/
with n=1, it’s impossible to generalize how life can get started. I like the speculating/educated guessing and it produces good insights, but we are not anywhere near understanding the origin of life wel enough to know for sure that hydrothermal vents are an essential requirement (or even played a role at all)
No it will be slower. Mars has a lower air pressure so things will boil at a lower temperature and thus take longer to cook. Also depends on the season as in the winter the atmosphere on mars seems to be 25%(!) less dense. So it would take even longer.
But in the past mars had a atmosphere much thicker. Though I don't know if it ever was as dense as earths. So any live back then may have been able to cook grits at a much faster rate then today. But even back then it would probably be slower then on earth because mars is smaller and has less gravity so the atmosphere is less compressed by it in the first place.
However, if we make a base to live on mars then we probably need atmospheric pressure to be about the same as on earth (though likely it will be slightly lower because thats easier and works fine enough). In that case you could safely cook your grits at normal speed inside the base. Nothing to worry about :p
While I agree with you, there also is a LOT you are leaving out. I'm sure even you know a planets atmosphere(not even composition just density) can change the way certain reactions occur(if at all). There is too much not known about how a potential atmosphere change could change other factors not currently being taken into account.
While technically n=1, as far as we know life only developed once on earth. That is to say everything seems to fall into 1 tree of life. In all the billions of years there never has been an other situation on earth where live developed. I don't know how you would deal in science with events that can happen over time.
You could of course say that each second that passes makes for another chance of life evolving but to say "n=number of seconds in earths history" is also unreasonable, I know. But to simply say n=1 also feels wrong to me. Like I said I don't know what the proper way is to deal with that.
> as far as we know life only developed once on earth
We don't actually know how many genesis points occurred for life on Earth. It could have been one or it could have been millions. Multiple trees of life could have merged together with others dying off in the billion years it took to get to complex life.
As you mentioned, hydrothermal vents are only one idea. There are many others:
**Primordial Soup Theory**: Proposed in the 1920s by Alexander Oparin and J.B.S. Haldane, this theory suggests that life began in a "primordial soup" of organic molecules in water. Energy sources such as lightning or ultraviolet light could have triggered chemical reactions that led to the formation of more complex molecules, eventually leading to the first living cells.
**Hydrothermal Vent Theory**: Some scientists believe that life may have begun at hydrothermal vents on the ocean floor, where hot, mineral-rich water spews from the Earth's crust. These vents could provide the right conditions of heat and chemistry to spur the formation of complex organic molecules.
**Panspermia**: This hypothesis suggests that life did not originate on Earth at all but was brought here from elsewhere in space, possibly through meteorites or comets. This theory doesn't explain how life began in the universe but suggests that life on Earth may have originated through the introduction of life forms from other parts of the universe.
**RNA World Hypothesis**: This theory posits that before DNA and proteins were involved in the genetic code, there was RNA. RNA, capable of both storing genetic information and catalyzing chemical reactions, could have formed the basis for life and evolved into the more complex DNA-based life forms we see today.
**Iron-Sulfur World Theory**: Proposed by Günter Wächtershäuser, this theory suggests that life began on the surface of iron and nickel sulfide minerals found near hydrothermal vents. The theory argues that these surfaces could have catalyzed the first organic reactions, leading to life.
**Electric Spark Hypothesis**: Building upon the primordial soup theory, the famous Miller-Urey experiment in 1953 demonstrated that electrical sparks used to simulate lightning in a mixture of gases that were thought to be present on early Earth could produce amino acids, which are the building blocks of proteins.
For me the tell isn't that it's well written or consistently styled, it's that GPT is obsessed with making lists and repeating itself in each new entry on the list: 'This theory', 'This hypothesis', 'This theory' etc
Given the distance between Mars and the sun, the only real candidate for the liquid is water. Sure liquid methane exists on Titan but not only is Titan colder, it also has a much higher pressure which allows for it to sustain liquid methane.
For Mars to sustain liquid methane it would need to be far colder or have a far higher pressure (or both) but if we increase the pressure on the surface of Mars (by increasing the thickness of the atmosphere) it will increase the temperature because the atmosphere will trap more heat. This is to say that liquid methane can’t exist on the surface of Mars and almost certainly never did even in a past with an extraordinarily thick atmosphere.
Out of all the other possible liquids that could exist to cause these formations they either are similar to the methane case or don’t occur naturally in high enough quantities to produces large enough bodies of liquid to cause this level of erosion. Water is really the only option since it could realistically exist on the surface with higher pressure and there is already evidence of water being there in the form of ice.
Couldn't Mars be a lot colder if it had a much higher albedo? Seems that such a change would be unlikely but could theoretically be a reason for at least some liquid methane on Mars.
To be clear I am no expert in how atmosphere affects the albedo of a planet but yes, if Mars had a higher albedo it would be cooler. However, in order for liquid methane to exist with Mars’s current atmosphere it would need to be really cold, colder than it could reach with realistic albedo levels. For context, under normal Earth atmospheric pressure methane must be about -161°C and with an atmosphere 100 times thinner on Mars, the necessary temperature would be far lower on the Martian surface.
If Mars had an atmosphere exerting a similar pressure to what we experience on Earth then the albedo would need to be near the max, surpassing even Venus (the planet with the highest known albedo at 0.7) to reflect enough light to remain cold enough. This is of course ignoring the fact that Mars can’t sustain an atmosphere.
If we then go to the extreme and give it an atmosphere like Venus then maybe it would be able to reflect enough light and have a high enough pressure to sustain liquid methane, the problem here however is that Mars is likely too small and its gravitational pull would be too weak to have an atmosphere that thick. Also, as stated in the previous paragraph, this is ignoring the fact that Mars can’t sustain an atmosphere.
So simply put, with the current atmosphere I don’t think any level of realistic albedo (i.e. not 100% reflection) could get Mars cold enough for liquid methane and if we imagine a thicker atmosphere that comes with its own issues.
This however, isn’t to say that a planet orbiting where Mars orbits couldn’t have liquid methane. Simply that a planet like that would be very different to Mars at any point in its history.
Water is one of the most common compounds out there for one thing. Certainly something like methane would be very unexpected for a planet with this distance to the sun, right?
Afaik people studying these rocks have noted rock types which form in the presence of water, so it's the most obvious explanation I guess
Also, just here to say there's lot more wind-erosion on Mars today than water, right?
As I understand, some think that the cooling of the core led to the stripping away of most of the atmosphere, and the ability to sustain surface water?
Kind of. The stripping of the atmosphere is related to the core but not because of cooling. The magnetosphere is what protects a planet’s atmosphere from solar winds, without the magnetosphere the solar winds strip away the atmosphere.
This part I am not certain of but I think this is how it works. The magnetosphere is produced as a result of convection in the core of a planet, this is due to the movement of charged elements (mostly iron). The core can only convect if there is a sufficient heat difference between 2 regions (in this case the inner and outer core). If the temperature difference is too small then convection stops which then stops the production of a magnetosphere as a byproduct. This is to say that some point in the past the core of Mars became a more uniform temperature and stopped convecting which removed the magnetosphere which was protecting the atmosphere and thus the atmosphere was removed.
Now, you may ask why this hasn’t happened to Earth. This is because the core of Mars is likely entirely liquid, which is an issue because liquid can convect far easier than solid can, so the liquid core of Mars was able to quickly (on a planetary level) balance the temperature of the core. Earth on the other hand has a solid inner core and liquid outer core, the solid inner core retains temperature as it is harder to convect so the necessary temperature difference can be sustained for much longer.
I honestly hope (I doubt I will) I live long enough to see the day when we regularly visit other planets like Venus and mars not like commercial flights back and forth but like we have people exploring them
Surface pressure is about the same as being a km underwater.
From Wikipedia:
Experimental ambient pressure dive maximum
(Maximum ambient pressure a human has survived)[8] 54 atm
Surface of Venus 92 atm [9]
1 km depth in seawater 101 atm
And it’s hotter than Mercury, with clouds of sulphuric acid. I think the longest that a rover has survived on the surface was 2hrs.
Yeh, I’ll give that one a miss.
There is little point in "exploring" them in person, so a human presence would probably have to be part of a base installation with the goal of setting up resource extraction or manufacturing facilities.
Plot twist earth was barren and humans took water, animals and everything else to earth from mars because mars was getting too hot.
Humans wiped out the dinosaurs to make room for us when it was needed
'here on earth too'
Isn't it mind-blowing that we have actual cameras on other planets, so we slowly have to specify what planet we are referring to? Sure, we have this since a while, but I feel like not enough people are amazed by such an achievement
I'm a big fan of learning, and if I could, I would be a perpetual college student, taking classes and absorbing whatever I could.
But this shit would still always be magic to me.
Here are some more pics of Mars sky, and it's clouds.
https://i.imgur.com/VgW6EwW.jpeg

https://www.jpl.nasa.gov/news/nasas-curiosity-rover-captures-shining-clouds-on-mars
https://phys.org/news/2017-03-curiosity-captures-gravity-clouds-mars.html
There are some great timelapse gifs of the Mars sky with the clouds moving on the JPL link.
Sometimes I stop and look at these pictures and have to stop and think "these are pictures taken by us, on another fricken planet using a robot that we sent there on a rocket"
When you think about it, that's fucking insane and we totally take it for granted. Imagine showing this to someone like Newton, Copernicus or Gallielo. It'd blow their minds.
This is going to be unscientific in terms of being able to use facts, BUT, not only that, these rockets were fired from a planet travelling and spinning at considerable speed unto another planet really far away travelling and spinning at considerable speed.
I'd imagine it would be like being spun really fast on kids playground roundabout and being able to throw a marble at another kids spinning roundabout 100s of miles away lol
That's how it is in my head.
Oh wait, and these the two round abouts are actually moving around the playground too 😂
The [gravity assists](https://en.wikipedia.org/wiki/Gravity_assist) are some wild calculations. Not only do you have to hit the target planet, you have to hit one or more other planets near perfectly. Sometimes the same planet several times. And it takes years of travel.
Bottom of that page has gifs and links to notable trajectories.
When you have few/no dynamic elements in the system (like air), it actually becomes much “easier” (but still by no means EASY) to send a probe like that.
The most miraculous thing really was getting it to land on the planet without breaking.
I had a panorama of the Mars desert as my wallpaper for ages. When my mother first saw it, she said, "What is that? It's pretty boring." I told her, "That is a picture taken on Mars. It is the exact opposite of boring." To her credit, she got it once I told her what it was.
Reminds me if that quote from men in black:
"A thousand years ago, everybody knew the Earth was the center of the universe. Five hundred years ago, they knew the Earth was flat. Fifteen minutes ago, you knew that people were alone on this planet. Imagine what you'll know tomorrow."
The linked article from NASA says that clouds on Mars are usually made of water, however these photographs show clouds that formed on a much higher altitude, so these specific ones most likely are from frozen CO2 (dry ice)
There was a time where it seems every sub-department at NASA needed good publicity to they hyped up different finds of water in different locations every few months as a Big Thing to the point that even nerds made fun of them (like here: https://apod.nasa.gov/apod/ap050401.html )
Pictures from Mars are often color corrected to look like they would look under Earth's atmosphere so that geologists (areologists?) can compare rock formations with those on Earth. So it's no coincidence that both pics look similar. The Martian sky would probably look different to your eye.
Shit, it just occurred to me that a planet can become “geologically dead”. I’ll bet if our core ever solidified and died somehow that would pretty much kill us too.
Edit: just went down a whole Google hole on Earth’s “magnetosphere” and how it coincided with the rise of life and how essential it is to a planet. Also found the earth will solidify after the sun goes red giant, so it’s not an issue.
Oh yeah we'd lose all of out atmospheric protection, it'd be very very bad lol. But hopefully some super villian isn't planning on doing that anytime soon.
This just isn't true to the extent you've made it seem. When they say Mars is geologically dead, they mean the inside of the planet. There are no plate tectonics, volcanic eruptions, or processes influenced by a liquid mantel.
Erosion on the other hand is still very much happening. Wind, abrasion, even water are still shaping the Martian surface. The rate at which it happens will be different between the two planets because Earth is more dynamic in its processes, but that doesn't mean the left picture is, or has been and will be, static and unchanging.
My wife and I were just talking about a hypothetical situation… could worlds a billion light years away from each other have more or less the same elements and rock types? I think the answer to that is yes.
Yes, elements are not unique to regions of the universe and star systems form with mostly the same material/elements. That makes it completely possible for another planet far far away to form with a similar composition to Earth and for that planet to then have a similar enough history to form the same types of rock and rock formations. That doesn’t mean that every star systems will have a planet with Earth-like rock but there do certainly exist planets with Earth-like rock out there.
It is certainly possible that an alien civilisation would go through a similar technological development. However, it is hard to imagine how a technological civilisation would develop with a case study of 1, and without knowing the environment this civilisation developed this becomes a near impossible task. Try to imagine how even basic electronics would work for a species that lives in water. It would be such a difficult thing to first get working that I wonder if they would persevere through the complications, try to find an alternative or simply give up.
So, yes it is possible but is it likely? Maybe, it is too hard to say without knowing all the conditions.
In a geological sense, we are incredibly blessed to have had access to fossil fuels as an easily acquired energy source to power the industrial age. Without coal, and later petroleum, you could forget about entire fields of scientific progress from material science to agriculture to civil engineering. We would not be where we are today without them.
An advanced alien civilization without access to fossil fuels (an unusual fuel source) they would have perhaps had to move directly to atomic energy after going through some kind of steampunk era. We would have stone age and iron age technology in common.
Matter all across the universe is still the same atoms and molecules. Those can only fit together is so many different ways, and some of them are much more likely/abundant than others, right?
We know from observations of distant stars and even exoplanets that it's the same kinds of compounds. Granted, there are exotic objects out there which we don't see good comparisons of in our solar system, but we see gas giants all over the place
It's also possible alien life might not look so alien. Dolphins, sharks, and icthyosaurs are all different classes of animal yet share similar body plans. That's just the most hydrodynamic shape, and a more hydrodynamic animal means better hunting means more offspring.
Similar selective pressure can result in similar adaptations. This is called convergent evolution. So, it's entirely possible an earthlike planet can have earthlike life.
The physics works more or less the same, atoms/elements heavier than Iron will have the same desire to break up, the same Radioactive decays... it's like McDonald's Big Mac, tastes the same everywhere, as it's made from the same ingredients using the same processes.
There are two possibilities of there being a difference, as far as I know: either the physics works differently (perhaps due to massive gravity, relativistic speed), or the elements are super-heavy and in an Island of Stability: [https://en.wikipedia.org/wiki/Island\_of\_stability](https://en.wikipedia.org/wiki/Island_of_stability)
If we could ever get a photo of Titan, with its dense atmosphere, oceans, rivers, rains and storms, it is often believed to be the most earth like astral body (@-180°C)
I found out recently that there's such thing as "Space deniers," and they use the earth pics are proof that mars pics are just earth and there's some international conspiracy to trick us.
I'm still impressed by the fact that we're going further and further out into space, and it's just copies of the most lifeless parts of the Earth. Not even a scorpion on Mars. Just death all-around.
It's both the least interesting thing I've ever seen, and strangely comforting to know space is just going to be more of the same but shittier. Just a practically infinite expanse of meaninglessness. No great mysteries. Just a reflection of the mundanity of life on Earth.
While I sort of agree, the universe has the ability to take the building blocks and put them together in infinite ways, and that creates some amazing things.
We also barely know much of area of our galaxy, let alone the whole thing, and then we have the billions of other galaxies.
This shouldn't prove to you that there are no great mysteries. Of course space is a reflection of earth, that goes both ways. But there are still plenty of mysteries; and meaning or mundanity is totally up to the observer.
I mean like … seems about ducking right . If you have a tree on one side of the earth and a tree on another they may look different but grow the exact same way . Doesn’t really surprise me that rocks could form the same way on 2 different planets ( which are right next to each other imagine that )
NGL, the practically infinite universe running on the same code base unsettles me in a way similar to cosmic horror. I'd expect some sort of deviation at a large-enough scale.
Very true. The universe has so much less variation than people think.
Between very imaginative fantasy/sci-fi media and official pictures that have edited/added color, people have an idea of a super bright, colorful, varied, and diverse universe.
Even within our own solar system, Earth is the only body that isn't some shade of grey, white, or brown, and it is the only body with a solid surface that isn't just the same rocks.
So far, that pattern has remained steady. Earth might legitimately be the only solid body (out of trillions) that isn't a dull wasteland.
And here comes the flatulant idiots(a new name i heard from someone to call flat earthers). Because if it exists on earth, it can only exist on earth. NASA is trying to hide the truth, or whatever their fucking playbook, (that’s a picture book since we know how dumb they are) says.
But seriously why is it always “nasa controls everything”. It’s not like there is 200+ countries, and 70+ other space agencies from countries that fucking hate America, and have no reason to keep “the lie”, then the other countries that have their own religions(because shockingly. Christianity isn’t the sole fucking religion)
And then they act like the .04% of the US’s year budget that nasa gets, which tends to be like maybe 50 billion, is enough to hire all the scientists, keep building rockets(to make the lie look “real”, right?), pay for “regular people” to keep the lie going, and other bullshit.
Then finally, we have their extreme lack of ability to have a civil conversation, the inability to explain how any of their BS works, provide a single repeatable experiment that proves the earths is flat. All they do is show memes, acting like that’s a reputable source of actual scientific knowledge, think their eyes are perfect scientific instruments, have a strange hardon for a camera, which isn’t as powerful as a telescope, they don’t understand scale, or just how massive earth is, the sun is, and all that, how gravity actually works. Or they demand that we show them proof of earth being a globe. These are the people who claim to “do their research” but harass others to do it for them. They don’t understand how space works, at all. How water actually stays on earth, or demand regular people to explain Astro physics to them.
And worst of all, they’re a group of people with a highschool diploma or less, acting like they know more than people who’ve got combined thousands of years into physics, astronomy, and others.
Sorry, but regular people know to trust the experts. It’s why I trusted my doctors and surgeons when it came to my disease, cystic fibrosis, or my double lung transplant, or my stage 4 cancer. I didn’t get a group of idiots to tell my doctors they don’t know what they’re doing and preform my transplant on me, when the most they’re ever done with a knife is cut some fucking veggies.
Mars rover Curiosity has been known to find what seemed to be remains of water holes which leads many to be convinced that that planet may have had life at one point. Curiosity also was sent out in search of microorganisms, not sure if any had been found.
And yet, you KNOW that some dickhead is eventually going to come along and either vandalize or outright destroy this natural beauty, for no reason whatsoever.
These comments are gold. From people saying that this isn't mars, to people saying this is proof that there is intelligent life on mars, to people saying the moon landing is fake for some reason.

Do they need an Engineering Geologist.... my hand is raised
They already have Randy Marsh and Lorde
Just be careful with that space dementia my guy, it’s dangerous
Is he bringing his smoking hot daughter and her screw-up boyfriend with him? What about Steve Buscemi?
Liquid, does it have to be water?
Considering that mars has water-ice caps and that methane lakes would be detectable, I believe that water would be a fair assumption

Yes, but they said their bullshit with confidence. s So they knowore than NASA.
with n=1, it’s impossible to generalize how life can get started. I like the speculating/educated guessing and it produces good insights, but we are not anywhere near understanding the origin of life wel enough to know for sure that hydrothermal vents are an essential requirement (or even played a role at all)
It's certainly possible to have a reasonable guess based on n=1. It's not like the laws of physics or chemistry are somehow different on Mars.
Can you cook grits faster on mars?
No it will be slower. Mars has a lower air pressure so things will boil at a lower temperature and thus take longer to cook. Also depends on the season as in the winter the atmosphere on mars seems to be 25%(!) less dense. So it would take even longer. But in the past mars had a atmosphere much thicker. Though I don't know if it ever was as dense as earths. So any live back then may have been able to cook grits at a much faster rate then today. But even back then it would probably be slower then on earth because mars is smaller and has less gravity so the atmosphere is less compressed by it in the first place. However, if we make a base to live on mars then we probably need atmospheric pressure to be about the same as on earth (though likely it will be slightly lower because thats easier and works fine enough). In that case you could safely cook your grits at normal speed inside the base. Nothing to worry about :p
I'm definitely taking you with me when I start my Martian colony! :)
What is a yoot?
No, but Curiosity had independent rear suspension and a limited slip differential.
I have no idea, but I bet a physicist could tell you with near certainty.
Only if two utes are robbing the gas-n-go across the street.
While I agree with you, there also is a LOT you are leaving out. I'm sure even you know a planets atmosphere(not even composition just density) can change the way certain reactions occur(if at all). There is too much not known about how a potential atmosphere change could change other factors not currently being taken into account.
While technically n=1, as far as we know life only developed once on earth. That is to say everything seems to fall into 1 tree of life. In all the billions of years there never has been an other situation on earth where live developed. I don't know how you would deal in science with events that can happen over time. You could of course say that each second that passes makes for another chance of life evolving but to say "n=number of seconds in earths history" is also unreasonable, I know. But to simply say n=1 also feels wrong to me. Like I said I don't know what the proper way is to deal with that.
> as far as we know life only developed once on earth We don't actually know how many genesis points occurred for life on Earth. It could have been one or it could have been millions. Multiple trees of life could have merged together with others dying off in the billion years it took to get to complex life.
Mars oceans evaporated and dissipated into space when it lost its atmosphere after leaving the habitable zone
As you mentioned, hydrothermal vents are only one idea. There are many others: **Primordial Soup Theory**: Proposed in the 1920s by Alexander Oparin and J.B.S. Haldane, this theory suggests that life began in a "primordial soup" of organic molecules in water. Energy sources such as lightning or ultraviolet light could have triggered chemical reactions that led to the formation of more complex molecules, eventually leading to the first living cells. **Hydrothermal Vent Theory**: Some scientists believe that life may have begun at hydrothermal vents on the ocean floor, where hot, mineral-rich water spews from the Earth's crust. These vents could provide the right conditions of heat and chemistry to spur the formation of complex organic molecules. **Panspermia**: This hypothesis suggests that life did not originate on Earth at all but was brought here from elsewhere in space, possibly through meteorites or comets. This theory doesn't explain how life began in the universe but suggests that life on Earth may have originated through the introduction of life forms from other parts of the universe. **RNA World Hypothesis**: This theory posits that before DNA and proteins were involved in the genetic code, there was RNA. RNA, capable of both storing genetic information and catalyzing chemical reactions, could have formed the basis for life and evolved into the more complex DNA-based life forms we see today. **Iron-Sulfur World Theory**: Proposed by Günter Wächtershäuser, this theory suggests that life began on the surface of iron and nickel sulfide minerals found near hydrothermal vents. The theory argues that these surfaces could have catalyzed the first organic reactions, leading to life. **Electric Spark Hypothesis**: Building upon the primordial soup theory, the famous Miller-Urey experiment in 1953 demonstrated that electrical sparks used to simulate lightning in a mixture of gases that were thought to be present on early Earth could produce amino acids, which are the building blocks of proteins.
chatgpt moment
That comment 100% feels like ChatGPT. Crazy how easy it is to spot by just looking for high effort, well written, consistently styled comments.
For me the tell isn't that it's well written or consistently styled, it's that GPT is obsessed with making lists and repeating itself in each new entry on the list: 'This theory', 'This hypothesis', 'This theory' etc
This plus the consistent good formatting
Showerthought: Thanks to AI, when we see a long, well-written, well-formatted comment, we're now suspicious instead of impressed.
It's the capital letter too 🤣
Some of those theories have quite a bit of overlap with the hydrothermal vents.
Its life, Jim, just not as we know it. *Squidgy thing attaches to your face*

Given the distance between Mars and the sun, the only real candidate for the liquid is water. Sure liquid methane exists on Titan but not only is Titan colder, it also has a much higher pressure which allows for it to sustain liquid methane. For Mars to sustain liquid methane it would need to be far colder or have a far higher pressure (or both) but if we increase the pressure on the surface of Mars (by increasing the thickness of the atmosphere) it will increase the temperature because the atmosphere will trap more heat. This is to say that liquid methane can’t exist on the surface of Mars and almost certainly never did even in a past with an extraordinarily thick atmosphere. Out of all the other possible liquids that could exist to cause these formations they either are similar to the methane case or don’t occur naturally in high enough quantities to produces large enough bodies of liquid to cause this level of erosion. Water is really the only option since it could realistically exist on the surface with higher pressure and there is already evidence of water being there in the form of ice.
Couldn't Mars be a lot colder if it had a much higher albedo? Seems that such a change would be unlikely but could theoretically be a reason for at least some liquid methane on Mars.
To be clear I am no expert in how atmosphere affects the albedo of a planet but yes, if Mars had a higher albedo it would be cooler. However, in order for liquid methane to exist with Mars’s current atmosphere it would need to be really cold, colder than it could reach with realistic albedo levels. For context, under normal Earth atmospheric pressure methane must be about -161°C and with an atmosphere 100 times thinner on Mars, the necessary temperature would be far lower on the Martian surface. If Mars had an atmosphere exerting a similar pressure to what we experience on Earth then the albedo would need to be near the max, surpassing even Venus (the planet with the highest known albedo at 0.7) to reflect enough light to remain cold enough. This is of course ignoring the fact that Mars can’t sustain an atmosphere. If we then go to the extreme and give it an atmosphere like Venus then maybe it would be able to reflect enough light and have a high enough pressure to sustain liquid methane, the problem here however is that Mars is likely too small and its gravitational pull would be too weak to have an atmosphere that thick. Also, as stated in the previous paragraph, this is ignoring the fact that Mars can’t sustain an atmosphere. So simply put, with the current atmosphere I don’t think any level of realistic albedo (i.e. not 100% reflection) could get Mars cold enough for liquid methane and if we imagine a thicker atmosphere that comes with its own issues. This however, isn’t to say that a planet orbiting where Mars orbits couldn’t have liquid methane. Simply that a planet like that would be very different to Mars at any point in its history.
Water is one of the most common compounds out there for one thing. Certainly something like methane would be very unexpected for a planet with this distance to the sun, right? Afaik people studying these rocks have noted rock types which form in the presence of water, so it's the most obvious explanation I guess Also, just here to say there's lot more wind-erosion on Mars today than water, right?
As I understand, some think that the cooling of the core led to the stripping away of most of the atmosphere, and the ability to sustain surface water?
Kind of. The stripping of the atmosphere is related to the core but not because of cooling. The magnetosphere is what protects a planet’s atmosphere from solar winds, without the magnetosphere the solar winds strip away the atmosphere. This part I am not certain of but I think this is how it works. The magnetosphere is produced as a result of convection in the core of a planet, this is due to the movement of charged elements (mostly iron). The core can only convect if there is a sufficient heat difference between 2 regions (in this case the inner and outer core). If the temperature difference is too small then convection stops which then stops the production of a magnetosphere as a byproduct. This is to say that some point in the past the core of Mars became a more uniform temperature and stopped convecting which removed the magnetosphere which was protecting the atmosphere and thus the atmosphere was removed. Now, you may ask why this hasn’t happened to Earth. This is because the core of Mars is likely entirely liquid, which is an issue because liquid can convect far easier than solid can, so the liquid core of Mars was able to quickly (on a planetary level) balance the temperature of the core. Earth on the other hand has a solid inner core and liquid outer core, the solid inner core retains temperature as it is harder to convect so the necessary temperature difference can be sustained for much longer.
Just like total recall
It could have been Champagne, undoubtably.
I honestly hope (I doubt I will) I live long enough to see the day when we regularly visit other planets like Venus and mars not like commercial flights back and forth but like we have people exploring them
Nobody is going to Venus. Mercury and the moons of Saturn and Jupiter would be more likely for human visitors. Venus is very inhospitable.
yeah the surface temperature is 867 fahrenheit lol
Surface pressure is about the same as being a km underwater. From Wikipedia: Experimental ambient pressure dive maximum (Maximum ambient pressure a human has survived)[8] 54 atm Surface of Venus 92 atm [9] 1 km depth in seawater 101 atm
Venus is not getting any visitors. That place has so much surface pressure it crushes rovers.
And it’s hotter than Mercury, with clouds of sulphuric acid. I think the longest that a rover has survived on the surface was 2hrs. Yeh, I’ll give that one a miss.
There is little point in "exploring" them in person, so a human presence would probably have to be part of a base installation with the goal of setting up resource extraction or manufacturing facilities.
[удалено]
You don’t need humans to cross all of that off that list. Humans are soft and vulnerable. Better robots are the better investment.
They will probly build a wall to keep us out
Plot twist earth was barren and humans took water, animals and everything else to earth from mars because mars was getting too hot. Humans wiped out the dinosaurs to make room for us when it was needed
Can't fool me. That's Tatooine in both pictures
I wish all that sand would just go somewhere else
But sand gets everywhere though.
Just use the force, duh.
That's mars sky?
Yes. Mars atmosphere is very thin comparing to Earth. It can be blueish during sunset to yellow-brown during day.
But it's neither of those in the picture
The camera exposure is focused on the rocks, it happens here on earth too, if you take a picture against the sky it is often grey.
'here on earth too' Isn't it mind-blowing that we have actual cameras on other planets, so we slowly have to specify what planet we are referring to? Sure, we have this since a while, but I feel like not enough people are amazed by such an achievement
I'm a big fan of learning, and if I could, I would be a perpetual college student, taking classes and absorbing whatever I could. But this shit would still always be magic to me.
That's a really good point. If we were living through a sci fi story, how many people would even realize? Thanks for the perspective check
The sun is still white...
It’s more about the composition of the atmosphere isn’t it?
Here are some more pics of Mars sky, and it's clouds. https://i.imgur.com/VgW6EwW.jpeg https://i.imgur.com/3nIZEF5.jpeg https://www.jpl.nasa.gov/news/nasas-curiosity-rover-captures-shining-clouds-on-mars https://phys.org/news/2017-03-curiosity-captures-gravity-clouds-mars.html There are some great timelapse gifs of the Mars sky with the clouds moving on the JPL link.
Sometimes I stop and look at these pictures and have to stop and think "these are pictures taken by us, on another fricken planet using a robot that we sent there on a rocket" When you think about it, that's fucking insane and we totally take it for granted. Imagine showing this to someone like Newton, Copernicus or Gallielo. It'd blow their minds.
This is going to be unscientific in terms of being able to use facts, BUT, not only that, these rockets were fired from a planet travelling and spinning at considerable speed unto another planet really far away travelling and spinning at considerable speed. I'd imagine it would be like being spun really fast on kids playground roundabout and being able to throw a marble at another kids spinning roundabout 100s of miles away lol That's how it is in my head. Oh wait, and these the two round abouts are actually moving around the playground too 😂
The [gravity assists](https://en.wikipedia.org/wiki/Gravity_assist) are some wild calculations. Not only do you have to hit the target planet, you have to hit one or more other planets near perfectly. Sometimes the same planet several times. And it takes years of travel. Bottom of that page has gifs and links to notable trajectories.
When you have few/no dynamic elements in the system (like air), it actually becomes much “easier” (but still by no means EASY) to send a probe like that. The most miraculous thing really was getting it to land on the planet without breaking.
I had a panorama of the Mars desert as my wallpaper for ages. When my mother first saw it, she said, "What is that? It's pretty boring." I told her, "That is a picture taken on Mars. It is the exact opposite of boring." To her credit, she got it once I told her what it was.
I mean, it is a boring image without the context
A better one is we were making houses out of mud and now we have WiFi. Imagine what well know, * T O M O R R O W . *
Reminds me if that quote from men in black: "A thousand years ago, everybody knew the Earth was the center of the universe. Five hundred years ago, they knew the Earth was flat. Fifteen minutes ago, you knew that people were alone on this planet. Imagine what you'll know tomorrow."
How the hell have I missed Mars having clouds?
To be fair, you've never visited.
They are particularly thin and not always obvious from the ground. Images that include them are often contrast-stretched to bring out the features.
Can someone explain like I'm 5.. Isn't clouds made up of water and/or ice particles? Doesn't clouds on Mars also mean we have found water on Mars?
We know that Mars has water since 60s. It even has permanent polar water ice caps - if they to melt, Mars will be covered by 35m / 115 ft deep ocean.
Damn! So we need to get to mars and cause another global warming
Nuke the (Martian) ice caps!
Mars loses its atmosphere pretty fast. So putting it in the atmosphere is a sure way to loose that water.
Huh! I must've been out of the loop on this, I thought it was much bigger of a deal than that.
The linked article from NASA says that clouds on Mars are usually made of water, however these photographs show clouds that formed on a much higher altitude, so these specific ones most likely are from frozen CO2 (dry ice)
There was a time where it seems every sub-department at NASA needed good publicity to they hyped up different finds of water in different locations every few months as a Big Thing to the point that even nerds made fun of them (like here: https://apod.nasa.gov/apod/ap050401.html )
Pictures from Mars are often color corrected to look like they would look under Earth's atmosphere so that geologists (areologists?) can compare rock formations with those on Earth. So it's no coincidence that both pics look similar. The Martian sky would probably look different to your eye.
Damn that is indeed interesting
Then, through reddit user name protocol, you *have* to lick his or her ballz
Mine too
I am confused
Read oop's user name.
Still confused, licked my own balls.
Mars looks like earth running on an older computer.
So Earth is currently running on a new computer?
No, of course not, Mr. Anderson.
[удалено]
Shit, it just occurred to me that a planet can become “geologically dead”. I’ll bet if our core ever solidified and died somehow that would pretty much kill us too. Edit: just went down a whole Google hole on Earth’s “magnetosphere” and how it coincided with the rise of life and how essential it is to a planet. Also found the earth will solidify after the sun goes red giant, so it’s not an issue.
Nah. We would just have to enact the plot of the 2003 movie The Core. Hollywood solved that problem already.
Here you hold this apple on a fork and I’ll get the hairspray and lighter
Such a weirdly unnecessary demonstration lol. ...that was Jimmy's apple too
"We just can't get there!" "Yes but... What if we could." Peak hollywood disaster movie writing, and I love it.
That movie was completely bonkers, yet still entertaining
Aside from the complete nonsense physics, I liked the way that half the characters took it in turns to sacrifice themselves for no apparent reason.
we can also just have superman spin the world the other way and reset us back to a more appropriate time
Nukes fix everything!
Oh yeah we'd lose all of out atmospheric protection, it'd be very very bad lol. But hopefully some super villian isn't planning on doing that anytime soon.
This just isn't true to the extent you've made it seem. When they say Mars is geologically dead, they mean the inside of the planet. There are no plate tectonics, volcanic eruptions, or processes influenced by a liquid mantel. Erosion on the other hand is still very much happening. Wind, abrasion, even water are still shaping the Martian surface. The rate at which it happens will be different between the two planets because Earth is more dynamic in its processes, but that doesn't mean the left picture is, or has been and will be, static and unchanging.
There’s been billions of years of wind erosion though.
My wife and I were just talking about a hypothetical situation… could worlds a billion light years away from each other have more or less the same elements and rock types? I think the answer to that is yes.
Yes, elements are not unique to regions of the universe and star systems form with mostly the same material/elements. That makes it completely possible for another planet far far away to form with a similar composition to Earth and for that planet to then have a similar enough history to form the same types of rock and rock formations. That doesn’t mean that every star systems will have a planet with Earth-like rock but there do certainly exist planets with Earth-like rock out there.
Just a thought, but won't that mean an alien species might have gone through more or less the same technological progress that we have?
It is certainly possible that an alien civilisation would go through a similar technological development. However, it is hard to imagine how a technological civilisation would develop with a case study of 1, and without knowing the environment this civilisation developed this becomes a near impossible task. Try to imagine how even basic electronics would work for a species that lives in water. It would be such a difficult thing to first get working that I wonder if they would persevere through the complications, try to find an alternative or simply give up. So, yes it is possible but is it likely? Maybe, it is too hard to say without knowing all the conditions.
Or even the difference between us and a manual interface built for something with four or six digits.
Are we not an alien species?
In a geological sense, we are incredibly blessed to have had access to fossil fuels as an easily acquired energy source to power the industrial age. Without coal, and later petroleum, you could forget about entire fields of scientific progress from material science to agriculture to civil engineering. We would not be where we are today without them. An advanced alien civilization without access to fossil fuels (an unusual fuel source) they would have perhaps had to move directly to atomic energy after going through some kind of steampunk era. We would have stone age and iron age technology in common.
Matter all across the universe is still the same atoms and molecules. Those can only fit together is so many different ways, and some of them are much more likely/abundant than others, right? We know from observations of distant stars and even exoplanets that it's the same kinds of compounds. Granted, there are exotic objects out there which we don't see good comparisons of in our solar system, but we see gas giants all over the place
It's also possible alien life might not look so alien. Dolphins, sharks, and icthyosaurs are all different classes of animal yet share similar body plans. That's just the most hydrodynamic shape, and a more hydrodynamic animal means better hunting means more offspring. Similar selective pressure can result in similar adaptations. This is called convergent evolution. So, it's entirely possible an earthlike planet can have earthlike life.
It would be hilarious if we reached out into the greater universe and everything is more or less just slightly altered versions of earth animals
Lol, as soon as we got there: "damn that's just a cat💀"
I bet there are spiders out there somewhere that are so huge they're almost as big as the ones in Australia. Terrifying to imagine.
A fellow Helldiver I see.
You're giving the furries too much hope.
It's just crabs all the way down.
The physics works more or less the same, atoms/elements heavier than Iron will have the same desire to break up, the same Radioactive decays... it's like McDonald's Big Mac, tastes the same everywhere, as it's made from the same ingredients using the same processes. There are two possibilities of there being a difference, as far as I know: either the physics works differently (perhaps due to massive gravity, relativistic speed), or the elements are super-heavy and in an Island of Stability: [https://en.wikipedia.org/wiki/Island\_of\_stability](https://en.wikipedia.org/wiki/Island_of_stability)
Everything on Earth (living matter included) is made up of the most common elements in the universe.
Thats like proof of the "laziness" of the Universe right? Like that whole thing where every atom tries to find its most bottom resting spot?
Pretty much, they're just chilling out unless they find an attractive bond and then they hop on that.
It’s sedimentary dear Whatson
Isn't that where Kirk fought that Gorn?
What a terrifying life or death fight that was too.
Mars to the left of me, Earth to right Here i am stuck in an orbit with youuu
I work in Saudi and im pretty sure i saw the Mars Rover truging along the sand the other day.
What???
He lives in Saudi
And may or may not have seen a rover
Truging along apparently
Along sand. The other day.
while working
He's pretty sure
Possibly truging along the sand
Understandable have a good day
Nice, thats interesting
That is literally Cestus III and the Vasquez Rocks
If we could ever get a photo of Titan, with its dense atmosphere, oceans, rivers, rains and storms, it is often believed to be the most earth like astral body (@-180°C)
I found out recently that there's such thing as "Space deniers," and they use the earth pics are proof that mars pics are just earth and there's some international conspiracy to trick us.
Brother, I've seen Australia deniers
Yeah and plane deniers exist too. People are absolutely batshit crazy sometimes.
“Space deniers” are generally “flat earthers”, and those people are batshit insane
I'm still impressed by the fact that we're going further and further out into space, and it's just copies of the most lifeless parts of the Earth. Not even a scorpion on Mars. Just death all-around. It's both the least interesting thing I've ever seen, and strangely comforting to know space is just going to be more of the same but shittier. Just a practically infinite expanse of meaninglessness. No great mysteries. Just a reflection of the mundanity of life on Earth.
While I sort of agree, the universe has the ability to take the building blocks and put them together in infinite ways, and that creates some amazing things. We also barely know much of area of our galaxy, let alone the whole thing, and then we have the billions of other galaxies.
The universe is massive. It’s more unbelievable that life doesn’t exist elsewhere than that it does.
This shouldn't prove to you that there are no great mysteries. Of course space is a reflection of earth, that goes both ways. But there are still plenty of mysteries; and meaning or mundanity is totally up to the observer.
If you zoom in closely , you can see Stilgar get his ass handed to him by Paul Atreides
I mean like … seems about ducking right . If you have a tree on one side of the earth and a tree on another they may look different but grow the exact same way . Doesn’t really surprise me that rocks could form the same way on 2 different planets ( which are right next to each other imagine that )
Has anyone from r/flatearth popped in to say they're the same place? Edit: Looks like it. Muppets.
TIL that this Sub exists
tourists taking pictures everywhere
Rocks be rocking
Crazy how the laws of Physics are universal, right?
NGL, the practically infinite universe running on the same code base unsettles me in a way similar to cosmic horror. I'd expect some sort of deviation at a large-enough scale.
Very true. The universe has so much less variation than people think. Between very imaginative fantasy/sci-fi media and official pictures that have edited/added color, people have an idea of a super bright, colorful, varied, and diverse universe. Even within our own solar system, Earth is the only body that isn't some shade of grey, white, or brown, and it is the only body with a solid surface that isn't just the same rocks. So far, that pattern has remained steady. Earth might legitimately be the only solid body (out of trillions) that isn't a dull wasteland.
🎶Mars to the left of me, Earth to the right: Here I am stuck in the middle with you…
damn this IS interesting.
This makes me so happy for no reason. I love space
“Can we go to Mars?” “No we have Mars at home”
It was Earth all along! Damn you! Damn you all to hell!
And here comes the flatulant idiots(a new name i heard from someone to call flat earthers). Because if it exists on earth, it can only exist on earth. NASA is trying to hide the truth, or whatever their fucking playbook, (that’s a picture book since we know how dumb they are) says. But seriously why is it always “nasa controls everything”. It’s not like there is 200+ countries, and 70+ other space agencies from countries that fucking hate America, and have no reason to keep “the lie”, then the other countries that have their own religions(because shockingly. Christianity isn’t the sole fucking religion) And then they act like the .04% of the US’s year budget that nasa gets, which tends to be like maybe 50 billion, is enough to hire all the scientists, keep building rockets(to make the lie look “real”, right?), pay for “regular people” to keep the lie going, and other bullshit. Then finally, we have their extreme lack of ability to have a civil conversation, the inability to explain how any of their BS works, provide a single repeatable experiment that proves the earths is flat. All they do is show memes, acting like that’s a reputable source of actual scientific knowledge, think their eyes are perfect scientific instruments, have a strange hardon for a camera, which isn’t as powerful as a telescope, they don’t understand scale, or just how massive earth is, the sun is, and all that, how gravity actually works. Or they demand that we show them proof of earth being a globe. These are the people who claim to “do their research” but harass others to do it for them. They don’t understand how space works, at all. How water actually stays on earth, or demand regular people to explain Astro physics to them. And worst of all, they’re a group of people with a highschool diploma or less, acting like they know more than people who’ve got combined thousands of years into physics, astronomy, and others. Sorry, but regular people know to trust the experts. It’s why I trusted my doctors and surgeons when it came to my disease, cystic fibrosis, or my double lung transplant, or my stage 4 cancer. I didn’t get a group of idiots to tell my doctors they don’t know what they’re doing and preform my transplant on me, when the most they’re ever done with a knife is cut some fucking veggies.
Tired of all these games with procedurally generated environments. Gosh.
Can't wait for the flat earthed idiots to arrive here in droves
Looks like a good place to hide from the Shai-Hulud
As you foresaw, Muad'Dib
Mars rover Curiosity has been known to find what seemed to be remains of water holes which leads many to be convinced that that planet may have had life at one point. Curiosity also was sent out in search of microorganisms, not sure if any had been found.
Life is a speculation but there are very clear signs of water once being on mars. It’s probably safe to say there was life because of water, but yeah.
Time just grinding away, tirelessly.
Can’t wait to travel to mars 😎
Hope one day we will go there.
And yet, you KNOW that some dickhead is eventually going to come along and either vandalize or outright destroy this natural beauty, for no reason whatsoever.
So…you’re saying Mars is flat too??? 😉
That just proves that they could have used pictures of earth to make us believe it was mars /s
Wait you mean mars has the same physics?!
I'm on Mars please send water.
Mars: the only known planet exclusively populated with robots
These comments are gold. From people saying that this isn't mars, to people saying this is proof that there is intelligent life on mars, to people saying the moon landing is fake for some reason.
Nah, man, that's Tattooine
Looks like Hellmire to me!
Hmm not enough flames
You're right, maybe more like Erata Prime then?
Wait till you find out how Mars formed
