Actually bare skin is relatively safe with liquid nitrogen for a small spill. It just evaporates before even touching the skin. Wearing clothes makes it worse. I know this from a few videos discussing extreme overclocking, a kind of “sport” where people use LN2 to cool computer chips (CPU or GPU) to try to get record performance or completion time in a given computation task.
Also, I do not believe in life on Mars. I have checked, didn't find any, so I checked all the history of Mars, there was no life there, and that's all to it, I guess?
Great job! Just a couple of points of constructive criticism: As a former member of ANSMET, there aren't shift changes: only one search shift per season. Some seasons there are two teams: recon and systematic, but we don't change shifts. Also, most cosmochemists now agree that the image with the bacteria-like shape is due to over-coating the sample for electron microscopic analysis and the organic PAHs are terrestrial contamination. I teach about this in my planetary geology classes and I'm happy to be a source of information if you would like to chat. Just google me.
Maybe you could answer my question. When I saw the picture of the meteorite that the ANSMET team was collecting I wondered why the rock was just sitting there on the surface. I mean, would it not have been blazing hot from atmospheric friction, melting into the snow??
@@pattoneill2402 Hi there. Good question. When meteorites fall, they are decelerating, which means by the time they get to the surface, most of them (smaller ones) are falling with a plop. Even if they were still hot when they fell, we find them in ice that has been eroded down by 1000's of years of katabatic winds. Any evidence of melted ice is long gone. The blue ice in Antarctica (where we find them) is on average 10's of thousands of years old. The winds erode the ice much faster than the rocks, so the meteorites are just sitting there on the surface. With increasing snow fall (due to climate change), they are getting harder to find b/c they are often covered in wind-carved snow drifts called sastrugi. Does this help answer your question?

Excellent video as always Anton! You were working in a lab for a professor investigating this bacterial Martian rock in the early 2000s?! Incredivle that means you'll be in your 5th decade like myself. Interesting start to you adult work life ;-)

Very interesting I had no idea that sample in the famous Mars rock was that small. I can't wait to see when one day they sample one of those craters with frozen ice in them same for the ones on the Moon.
I recall when one of the Science magazines later debunked excitement over the discovery - each page of the article having the same image of the rock with less and less forests and life painted on it until there were none.
Anton, since you seem to know a lot about rocks and minerals, would be great if you could release a couple of videos on that as well 🙂. I bought a book, it's nice, but the way you explain things is so much more digestible. Thank you!
I agree. It sounds oddly specific. I assume that area is the closest match chemically (spectroscopy), but it can't possibly be a definitive statement. Assuming that it did in fact originate there when they think it did, by what mechanism was it thrown off at > escape velocity? Automatically, they'll say ejected during an impact. But the Vales Marinaris (sp?) is quite the dramatic feature to say the least: perhaps the meteorite was ejected during the formation of V.M. itself, implying a catastrophic formation of V.M. instead of a slow geologic one. I mean, if it's a canyon, where/what was it supposed to be draining into?
@@JeremyNasmith Since Anton showed a circular crater when he was talking about the origin point, it seemed like the origin was an impact crater in the vicinity of VM, not necessarily VM itself.
@@JeremyNasmith : As I recall, the _do_ think Valles Marinaris was formed in a catastrophic event. It would be very weird for such an event to cause a rock to reach escape velocity.
@championchap also its much more common for rocks that are knocked off planets to travel inward towards the sun.. ie. more rocks from mars landing on earth over billions of years than earth rocks landing on mars
Did a research project on this meteorite in University. The studies we looked at referred to satellites orbiting Mars taking "visual" data of the rock faces themselves, and matched them to the meteorite.
my mom also really wanted to be a scientist... and then realized it was just doing the same experiment over and over, writing reports all the time about the same boring reaction. and she didn't even get far enough to have to deal with PR!! technician work is where it's at
Ur amazing - I love ur ability to make a topic (that i would have found boring once upon a time) so fascinating is testiment to the amazing person u are. Luv ur Vids.
Although "Noachian" is a reference to the flood story in Genesis, I somehow regard any expectation to find evidence of a giant wooden boat filled with animals to be a bit overly optimistic.
Thanks Anton. Nice to learn a bit about you. I was pretty excited when Clinton made his announcement. It didn't take long to get me back down to earth, so to speak.
It's scary to me to think that the reason Mars dried out was because its core cooled down. I'm starting to wonder if there is a threshold for core sizes
Two main thoughts -- #1 thanks for sharing everything from a scientific perspective -- #2 stay open to all possibilities (but also keep occam's razor in mind)
Kind of like when the "water" they found on Mars turned out to be basalt. They have never found water on Mars. What they have is a radar scan and they guess at what shows up on the scan. One guy guessed it was water and everyone freaked out. Turns out it was actually the same as when they scan basalt because it's basalt, not water.
Because they are fossils. It’s literally there and they couldn’t come up with an explanation for almost 30 years. There explanation is asinine and naive to think it could only be caused by certain chemical reactions. What about the possibility of it really being life? Why is the most simplest and most plausible explanation rejected?
@@musiclovers-rq7ll I think that's the problem with science now. They will do anything to disprove alien life, without searching why it could be life. With this mentality we will never know about extraterrestrial life.
I helped Koreamet find 16 Antarctic meteorites in 2008. You snowmobile beside a mountain range that has been scoured free of snow to look for them, but there are thousands of rocks from the mountains too on the ice. You snowmobile all day long looking for the rock that doesn't look like the other thousands of rocks - not easy.
Nice work as usual, Anton. When I first heard this report, I was immediately skeptical too. There are too many possibilities for such forms to be produced inorganically. This, of course, does not show that there is or was no life on Mars. But we might well be unique in the Solar System, at least. Or not. cheers from rainy Vienna, Scott
I also started my interest in astrobiology back then, 1997. It were very exciting times.. Even with this turning out to be a false discovery, it sparket the entire NASA Mars exploration program!
@@joemcintyre2090 well actually we have a whole bunch of rocks from Mars. What are you talking about? You realize we have had robot explorers doing science on mars for over 20 years, right? Like these robots have the ability to pick up a rock, do a bunch of experiments and tests to it, and sometimes grind it up completely for more tests, or put it back.. Like we know Mars alot better than we know the botttom of our own oceans.
@@raidermaxx2324 I was unaware that any rocks have been sent back from our missions. I know that the current rovers are gathering samples to be picked up by another mission.
12:04 Right after saying the benefit of talking about something exciting, but yet unconfirmed, shoots down as if it were wrong. If potentially exciting discoveries are not(or reluctant to be) announced, before they are fully confirmed, what will inspire those who would have taken interest? Wouldn't it actually take longer to confirm or deny if there were less people in discourse? Rather everything possible should be announced as soon as possible, open mindedly, and updated as things progress, while also fully disclosing that it's unconfirmed.
Geological and geochemical process can create all sorts of regular looking patterns. The classic is the hexagonal convection cells seen as in the "Giants Causeway". Thermal cycles can even make rocks seem to move across the landscape. Just because the human mind has a tendency to 'see' patterns and shapes it knows, that does not mean that something with a vaguely familiar shape is related. Biologists pointed out originally that these structures in the Martian rock were much smaller than the cells found on Earth, so if they were Martian cells they would be more different than a first glance suggests.
it may be abiotic but it's still a very interesting rock! when it was announced back in the day i fiddled with some speculative evolution trying to make a bacterium that small work. i was not successful but maybe a biochemist might have better technique. you can engineer something an order of magnitude smaller than earth bacteria easily enough but that's as far as i got.
@@nutzeeer the problem with this rock is that it's two orders smaller or ~1% the size of the smallest bacteria we have on earth! that's just too small to fit all the machinery you need for basic life functions as we understand them. i personally use 'order of magnitude' when talking about relative sizes of things very big or very small that are hard to explain with just numbers. if you don't work with the unit regularly, how much is 200 nanometers to you? what does that measure relate to? anton is a science communicator so it's a very useful phrase for him.
Dear Anton I very much like your great presentations on various topics. Today you talked about something I am studying recently in some meteorite-like find in Sooke Basin in British Columbia. It is 13 kg, covered with fusion crust and attracts magnets - contains mostly pyroxene diopside and magnetite. I would say it can be achondrite, possibly even from Noachian period of Mars. Surprisingly it shows some sort of fossil about 2 mm in size. According to our Raman spectroscopy analysis it contains diamondized carbon in a form of lonsdaleite. Such tiny lonsdaleite crystals are being found in meteorite craters. It is believed that they form during impact shocks induced by meteoroids or asteroids. I can email to you brief summary of our Raman work to day, photographs and other data. But we still have a lot of work to have this find approved as meteorite. I would be very grateful for your comments and interest as the one of first astrobiologists. I am nuclear physicist and materials researcher. Jerzy A. Sawicki Victoria, BC, Canada
I collect, on my site locally fallen meteorites. And on one of sites I collected the splattered remains of a meteorite. These remains contained rustic magnetite. I know by experience that meteorites dont contain this mineral but this Martian meteorite changes things. I may have the powdered remains if a Martian specimen.
Well, it's not really the Olympus Mons that started that, or at least, it didn't happen on its own randomly. Diametrically, on the other side of the planet, there is Hellas Planitia, Mars' biggest and deepest crater. Chances are that whatever impacted there, disturbed the core and forced the emergence of Olympus Monss on the other side.
Whoa look at big brains @@celestus87 , seriously. i never thought about that. Clears some things up. Now i gotta do some research. Thanks you good sirS*! -jeff- I surprisingly never heard that theory.
People get to go out and ride snowmobiles for weeks at a time in Antarctica to look for rocks AND get paid for it? You just described a childhood dream job of mine I never thought would exist. Amazing 👏
Our current Mars obsession seems to be about locating water (in any form) and much research is devoted to that. What is intriguing in this presentation is the insistence of scientists that these minerals would have to have formed in the presence of H2O. Bazinga!
How can something that landed 13,000 years ago still be on the surface? Wouldn’t it’s momentum and heat from entry cause it to be buried at least a little bit…not to mention the accumulation of 13 millennia of constant snow and ice?
The interior of Antarctica gets very little snowfall; it's just too cold to snow. Some areas -- called Antarctic dry valleys -- are actually the driest places on Earth. Even outside these valleys, so little snow falls that glacier movement carries away the ice faster than it can be replenished. The continent is very slowly losing its ice cover regardless of global warming. Heating from atmospheric entry is complex. The leading edge of a meteorite may be vaporized by the heat, but stone isn't very conductive and the heating doesn't really last for very long. It's even been calculated that, had there been live microbes on Mars in the past, they could even have survived the trip to Earth!
Having the advantage of remembering the original group of scientists arguing that the second group's explanations included processes that could not have coexisted, I cannot help but wonder does the latest round of explanations include a series of events that could have all occurred to the same bit of rock?
yes, there are a few mechanisms depending on which take on physics you follow. high velocity impact can easily kick out objects as can high electric discharge
I believe Anton said it was froma region of Valles Marinaris and I don’t think there is impact crater there big enough to have sent this into orbit. Also given the relative distances where Mars and Earth are traveling and how debris from an impact would disperse it seems very improbable that it would even reach Earth except in the case of a bombardment but again there doesn’t seem to be evidence of bombardment in the region on mars where it was found. The fact that we find a lot of Martian meterorites on Earth means there had to at some point been a very large number of rocks thrown into orbit from Mars at some point for such a high number to reach Earth in the first place. It’s important to keep the scale in mind, these are huge distances and Mars and Earth are like specks of dust with respect to each other. Quite mind boggling.
Mars has half of earths escape velocity and nearly no atmosphere. So most glancing meteorites on earth will come in slower and need a much higher speed to create an earth meteorite.
Have a look at the moon. It is the result of a long-ago collision between the early Earth and a planet called Thea which was about the size of Mars. A huge amount of material was blasted into the sky. Some had exceeded escape velocity, never to return; some had insufficient velocity to escape and fell back to earth; but enough had sufficient velocity to go into orbit about 20,000 kilometres high, and initially formed a ring, which then coalesced over time into 2 moons, one much larger than the other. The second eventually collided with the first. So, long story short. massive impacts can and do blast material beyond the escape velocity of their planet. The energies involved are very destructive so a lot of that material may be pulverised or liquid. You will note that the moon is much further away now than 20,000 kilometres for complex tidal and angular momentum conservation reasons.
I was working at NASA back then at the JSC. It started by the director of NASA making a claim that NASA (Johnson Space Center) made a discovery that would shake the world by a few scientists at the JSC but they never had a peer review before making their claim. I remember one famous scientists outside of JSC after they made the claim that they discovered life on Mars from a meteorite that was supposedly from Mars that laid plain in the Antarctica for 10,000 years saying “extraordinary claims requires extraordinary proof”. It was soon after that many scientists rejected the JSC claim even saying that had seen this many times before and was not biological. Before anybody makes claims of this nature why not try and create life from scratch (from a sterile environment with all the proteins and ammo acids that you need). You find it impossible to do.
Should be interesting if the proposed Mars Sample Return project becomes reality and various samples, with known source location, can be brought directly to earth for detailed analysis. Even if the samples don't contain evidence of life, they will certainly give us a better understanding about the geological history of Mars.
I volunteer for the first taste test, think about, what if mars tastes delicious? I mean I'm still not convinced the moon isn't cheese. what if it just has a rocky rind and inside is a sea of gooey brie.
@@TheWebbNasty With all that reddish iron oxide on Mars' surface, I imagine the samples would leave a noticeably metallic aftertaste in your mouth. Unless you enjoy the taste metal, probably not particularly delicious. I have no comment on the moon cheese.

@@mauricegold9377 And God took the clay of the earth and breathed life into it. So much that science finds comes close to the poetry and inspiration of many sacred old writings. I originally thought is was because most life on earth was made of pretty much the same minerals, though poss arranged in different ways to that of the earth itself.

Excellent video as always Anton! You were working in a lab for a professor investigating this bacterial Martian rock in the early 2000s?! Incredivle that means you'll be in your 5th decade like myself. Interesting start to you adult work life ;-)
Anton, your videos are golden.. to the point, no dumb intro, good information, no BS... Love it.. keep up the great work
"spilling on my feet and burning my toes." LOL, um no, so sorry, ouch, LOL... um, nope, that had to hurt. .but.... lol.... dang it that still was too funny! Anton, you are hilarious, can't help laughing at your misadventures! Love your videos, learn so much.
Anton needs a PODCAST!
Yess
I second this opinion but I think would be too much. I am assuming Anton records a week worth of episodes in a day and uploads 22:00 GMT every day but to add a monthy podcast of an hour or so would be great... but also a lot more effort.
If he has a team of people he works with for these videos, it would be PRETTY COOL.
Also.. We need to see this handsome man too..tho..😬😌
Ah, yes, 84 double aught 1, the famous - er, infamous "alien life - whoops, not alien life" meteorite! One I won't ever forget, LOL!
Glad they delved this deep into the how & why of that little bugger that ruined our hopes back then. 😄 Thanks, Anton, for bringing this to us. And thanks for what you do for us, every day. You bring a bright spot to my dismal world, and I can't thank you enough for that. ❤❤🖖🏼😌
Thanks for the update but I kinda already figured that… it’s literally NEVER aliens. Ever.
Finally a thorough explanation of this topic! Thank you very much!
Very interesting I had no idea that sample in the famous Mars rock was that small. I can't wait to see when one day they sample one of those craters with frozen ice in them same for the ones on the Moon.
Wow its been a couple years. Its so good to see this channel grow
I love your channel Anton. You have great videos.
I recall when one of the Science magazines later debunked excitement over the discovery - each page of the article having the same image of the rock with less and less forests and life painted on it until there were none.
Sounds like a task for slow flying drone planes and some clever software analyzing the imagery
Thank you Anton. You are indeed a wonderful person and I enjoy your videos very much.
Anton, since you seem to know a lot about rocks and minerals, would be great if you could release a couple of videos on that as well 🙂. I bought a book, it's nice, but the way you explain things is so much more digestible. Thank you!
Yes, I've always wondered how those beautiful crystals form ... but frankly have been too lazy to find out. One vid by Anton would be nice.
I've been waiting for this since it came out!
What so, WHAT DO YOU DO, ANTON?? lol really skated over the finer details in that part, I was so excited to hear more.
Anton is an astrobiologist, teacher, youtuber, inspiration and of course a wonderful person
Wait, they figured out Where on Mars it came from, when it was ejected and also when it landed on earth? I’d like to know how they figured that out!
I agree. It sounds oddly specific. I assume that area is the closest match chemically (spectroscopy), but it can't possibly be a definitive statement.
Assuming that it did in fact originate there when they think it did, by what mechanism was it thrown off at > escape velocity? Automatically, they'll say ejected during an impact. But the Vales Marinaris (sp?) is quite the dramatic feature to say the least: perhaps the meteorite was ejected during the formation of V.M. itself, implying a catastrophic formation of V.M. instead of a slow geologic one. I mean, if it's a canyon, where/what was it supposed to be draining into?
@@JeremyNasmith Since Anton showed a circular crater when he was talking about the origin point, it seemed like the origin was an impact crater in the vicinity of VM, not necessarily VM itself.
@@JeremyNasmith : As I recall, the _do_ think Valles Marinaris was formed in a catastrophic event. It would be very weird for such an event to cause a rock to reach escape velocity.
@championchap also its much more common for rocks that are knocked off planets to travel inward towards the sun.. ie. more rocks from mars landing on earth over billions of years than earth rocks landing on mars
Did a research project on this meteorite in University. The studies we looked at referred to satellites orbiting Mars taking "visual" data of the rock faces themselves, and matched them to the meteorite.
my mom also really wanted to be a scientist... and then realized it was just doing the same experiment over and over, writing reports all the time about the same boring reaction. and she didn't even get far enough to have to deal with PR!!
technician work is where it's at

Although "Noachian" is a reference to the flood story in Genesis, I somehow regard any expectation to find evidence of a giant wooden boat filled with animals to be a bit overly optimistic.
Wonderful video explaining the whole field.
Thanks Anton. Nice to learn a bit about you.
I was pretty excited when Clinton made his announcement. It didn't take long to get me back down to earth, so to speak.
It's scary to me to think that the reason Mars dried out was because its core cooled down. I'm starting to wonder if there is a threshold for core sizes
There is. Mars also has no large moon to pull and stretch it to heat, like earth does. Such a world is doomed from the beginning
Two main thoughts -- #1 thanks for sharing everything from a scientific perspective -- #2 stay open to all possibilities (but also keep occam's razor in mind)
Thank you Anton (even though that info blew away my initial excitement from years ago) 😀

I remember this rock. Wow! What a job! Running around on snowmobiles looking for meteorites just laying there. Lov'in it!
Nice. Looking forward to those future vids.
Kind of like when the "water" they found on Mars turned out to be basalt. They have never found water on Mars. What they have is a radar scan and they guess at what shows up on the scan. One guy guessed it was water and everyone freaked out. Turns out it was actually the same as when they scan basalt because it's basalt, not water.
Have they ever found a rock with that structure on Earth? (like a real Earth rock, not one from space)
That rod shape in the Mars rock? Yeah, it's apparently pretty common.
Because they are fossils. It’s literally there and they couldn’t come up with an explanation for almost 30 years. There explanation is asinine and naive to think it could only be caused by certain chemical reactions. What about the possibility of it really being life? Why is the most simplest and most plausible explanation rejected?
@@musiclovers-rq7ll did you listen to the video ? Size too small, chemical process creating similar results much easier ?
@@musiclovers-rq7ll I think that's the problem with science now. They will do anything to disprove alien life, without searching why it could be life. With this mentality we will never know about extraterrestrial life.
@@duudsuufd no. That is how science works. You don't go around trying to prove what you want to be. That's religion.
I helped Koreamet find 16 Antarctic meteorites in 2008. You snowmobile beside a mountain range that has been scoured free of snow to look for them, but there are thousands of rocks from the mountains too on the ice. You snowmobile all day long looking for the rock that doesn't look like the other thousands of rocks - not easy.

Awesome thanks anton
Nice work as usual, Anton. When I first heard this report, I was immediately skeptical too. There are too many possibilities for such forms to be produced inorganically.
This, of course, does not show that there is or was no life on Mars. But we might well be unique in the Solar System, at least. Or not.

I've been wondering about those Mars Rocks for decades, Thanks.
I also started my interest in astrobiology back then, 1997. It were very exciting times.. Even with this turning out to be a false discovery, it sparket the entire NASA Mars exploration program!

Because they're made of the same stuff as Mars
@@oxcart4172 I don't believe we have any rock samples from Mars to verify this claim.
@@joemcintyre2090 well actually we have a whole bunch of rocks from Mars. What are you talking about? You realize we have had robot explorers doing science on mars for over 20 years, right?

Wait...Anton was a lab assistant for a professor in 1997? How old is Anton? All this time I thought he's in his 20s.
Great story! Thanks for sharing.
12:04 Right after saying the benefit of talking about something exciting, but yet unconfirmed, shoots down as if it were wrong.
If potentially exciting discoveries are not(or reluctant to be) announced, before they are fully confirmed, what will inspire those who would have taken interest?
Wouldn't it actually take longer to confirm or deny if there were less people in discourse?
Rather everything possible should be announced as soon as possible, open mindedly, and updated as things progress, while also fully disclosing that it's unconfirmed.
Excellent Reporting 👍
Fascinating, thank you 👍🏻👍🏻
Another fantastic video!
Geological and geochemical process can create all sorts of regular looking patterns. The classic is the hexagonal convection cells seen as in the "Giants Causeway". Thermal cycles can even make rocks seem to move across the landscape. Just because the human mind has a tendency to 'see' patterns and shapes it knows, that does not mean that something with a vaguely familiar shape is related. Biologists pointed out originally that these structures in the Martian rock were much smaller than the cells found on Earth, so if they were Martian cells they would be more different than a first glance suggests.
it may be abiotic but it's still a very interesting rock! when it was announced back in the day i fiddled with some speculative evolution trying to make a bacterium that small work. i was not successful but maybe a biochemist might have better technique. you can engineer something an order of magnitude smaller than earth bacteria easily enough but that's as far as i got.
Earth bacteria vary in size by orders of magnitude.
What is order of magnitude anyway. Why dont we say by decimals?
@@nutzeeer the problem with this rock is that it's two orders smaller or ~1% the size of the smallest bacteria we have on earth! that's just too small to fit all the machinery you need for basic life functions as we understand them. i personally use 'order of magnitude' when talking about relative sizes of things very big or very small that are hard to explain with just numbers. if you don't work with the unit regularly, how much is 200 nanometers to you? what does that measure relate to? anton is a science communicator so it's a very useful phrase for him.

Hello wonderful Anton this is person
Nice bushes the scooters drive by. Didn't know they have this in Antarctica...
Dear Anton
I very much like your great presentations on various topics.
Today you talked about something I am studying recently in some meteorite-like find in Sooke Basin in British Columbia.
It is 13 kg, covered with fusion crust and attracts magnets - contains mostly pyroxene diopside and magnetite.
I would say it can be achondrite, possibly even from Noachian period of Mars.
Surprisingly it shows some sort of fossil about 2 mm in size.
According to our Raman spectroscopy analysis it contains diamondized carbon in a form of lonsdaleite.
Such tiny lonsdaleite crystals are being found in meteorite craters.
It is believed that they form during impact shocks induced by meteoroids or asteroids.
I can email to you brief summary of our Raman work to day, photographs and other data.
But we still have a lot of work to have this find approved as meteorite.
I would be very grateful for your comments and interest as the one of first astrobiologists.
I am nuclear physicist and materials researcher.

I collect, on my site locally fallen meteorites. And on one of sites I collected the splattered remains of a meteorite. These remains contained rustic magnetite. I know by experience that meteorites dont contain this mineral but this Martian meteorite changes things. I may have the powdered remains if a Martian specimen.
I've often wondered what would have happened to Mars if Olympus Mons hadn't happened and Mars hadn't lost its magnetic field.
...what do you mean?
Well, it's not really the Olympus Mons that started that, or at least, it didn't happen on its own randomly. Diametrically, on the other side of the planet, there is Hellas Planitia, Mars' biggest and deepest crater. Chances are that whatever impacted there, disturbed the core and forced the emergence of Olympus Monss on the other side.
Whoa look at big brains @@celestus87 , seriously. i never thought about that. Clears some things up. Now i gotta do some research. Thanks you good sirS*! -jeff-

That must have been one hell of a wallop for rocks to escape mars’ gravity.
a lot more than "one wallop" over the years lol
The gravity on Mars is 0.375 x gravity on Earth and the atmosphere on Mars is 100 times less dense than on Earth, one hell of a whack is subjective.

Our current Mars obsession seems to be about locating water (in any form) and much research is devoted to that. What is intriguing in this presentation is the insistence of scientists that these minerals would have to have formed in the presence of H2O. Bazinga!
Thank you, kind Sir!
A somewhat rocky path for Anton, but it turned out great ;)
How can something that landed 13,000 years ago still be on the surface? Wouldn’t it’s momentum and heat from entry cause it to be buried at least a little bit…not to mention the accumulation of 13 millennia of constant snow and ice?
The interior of Antarctica gets very little snowfall; it's just too cold to snow. Some areas -- called Antarctic dry valleys -- are actually the driest places on Earth. Even outside these valleys, so little snow falls that glacier movement carries away the ice faster than it can be replenished. The continent is very slowly losing its ice cover regardless of global warming.
Heating from atmospheric entry is complex. The leading edge of a meteorite may be vaporized by the heat, but stone isn't very conductive and the heating doesn't really last for very long. It's even been calculated that, had there been live microbes on Mars in the past, they could even have survived the trip to Earth!
Seeing the title - clickbait! Seeing the channel - no it‘s serious! Interesting vid!
Like the bit of humour❣️
Love this show!!!!🤓
Having the advantage of remembering the original group of scientists arguing that the second group's explanations included processes that could not have coexisted, I cannot help but wonder does the latest round of explanations include a series of events that could have all occurred to the same bit of rock?
I see you couldn't find any stock footage of snow mobiles in Antarctica ?
There's not exactly a lot of plant life (trees and shrubs) there ! LOL
I love hearing the "inciting incident" that gets folks into science! Not CZcams algo friendly on its own, but awesome to hear weaved in 👌💚
I'm curious how rocks on Mars (or any planet for that matter) can reach escape velocity. Do terrestrial rocks do this and how?
yes, there are a few mechanisms depending on which take on physics you follow. high velocity impact can easily kick out objects as can high electric discharge
I believe Anton said it was froma region of Valles Marinaris and I don’t think there is impact crater there big enough to have sent this into orbit. Also given the relative distances where Mars and Earth are traveling and how debris from an impact would disperse it seems very improbable that it would even reach Earth except in the case of a bombardment but again there doesn’t seem to be evidence of bombardment in the region on mars where it was found.
The fact that we find a lot of Martian meterorites on Earth means there had to at some point been a very large number of rocks thrown into orbit from Mars at some point for such a high number to reach Earth in the first place. It’s important to keep the scale in mind, these are huge distances and Mars and Earth are like specks of dust with respect to each other. Quite mind boggling.
volcanic eruptions
Mars has half of earths escape velocity and nearly no atmosphere. So most glancing meteorites on earth will come in slower and need a much higher speed to create an earth meteorite.
Have a look at the moon. It is the result of a long-ago collision between the early Earth and a planet called Thea which was about the size of Mars. A huge amount of material was blasted into the sky. Some had exceeded escape velocity, never to return; some had insufficient velocity to escape and fell back to earth; but enough had sufficient velocity to go into orbit about 20,000 kilometres high, and initially formed a ring, which then coalesced over time into 2 moons, one much larger than the other. The second eventually collided with the first. So, long story short. massive impacts can and do blast material beyond the escape velocity of their planet. The energies involved are very destructive so a lot of that material may be pulverised or liquid. You will note that the moon is much further away now than 20,000 kilometres for complex tidal and angular momentum conservation reasons.
I was working at NASA back then at the JSC. It started by the director of NASA making a claim that NASA (Johnson Space Center) made a discovery that would shake the world by a few scientists at the JSC but they never had a peer review before making their claim. I remember one famous scientists outside of JSC after they made the claim that they discovered life on Mars from a meteorite that was supposedly from Mars that laid plain in the Antarctica for 10,000 years saying “extraordinary claims requires extraordinary proof”. It was soon after that many scientists rejected the JSC claim even saying that had seen this many times before and was not biological. Before anybody makes claims of this nature why not try and create life from scratch (from a sterile environment with all the proteins and ammo acids that you need). You find it impossible to do.
Should be interesting if the proposed Mars Sample Return project becomes reality and various samples, with known source location, can be brought directly to earth for detailed analysis. Even if the samples don't contain evidence of life, they will certainly give us a better understanding about the geological history of Mars.
I volunteer for the first taste test, think about, what if mars tastes delicious? I mean I'm still not convinced the moon isn't cheese. what if it just has a rocky rind and inside is a sea of gooey brie.
@@TheWebbNasty With all that reddish iron oxide on Mars' surface, I imagine the samples would leave a noticeably metallic aftertaste in your mouth. Unless you enjoy the taste metal, probably not particularly delicious. I have no comment on the moon cheese.
Thanks Anton! 🇸🇪👍
