How Scientists Proved These Rocks Came From Mars. 

Yeah. As a kid I use to think like "I bet they know because they are red just like mars" lol.

@@MegaBanne I mean, at the very least that's a reasonable guess.

Ditto. I wasn't sure that such claims weren't myth but thanks for clearing it up nicely Scott. Totally puzzled by the fact that there are down-votes against the article. Perhaps by people that remain unconvinced.

@@nickhewett8815 Particularly since Scott was rather clear that we cannot confirm this until completion of a sample/return mission.

@@nickhewett8815 Downvote rates of less than 1% are pretty good. There will always be a few downvotes because RU-vid recommended the video to someone that wasn't interested, etc.

With how hard, and often the Earth was pummeled in its early life, I wouldn't be surprised of parts of it made it to other planets, or are even zooming around waiting for a curious species to study it.

Absolutely. My understanding is it's more likely for Mars rocks to hit Earth than the other way around (Mara is "uphill" from Earth), but it's definitely a possibility.

I don't think there's much question about this. I mean regardless of what orbits where(other than the obvious impacts shearing off chunks and flinging into space)...it makes more sense that there would be pieces of earth injected into other heavenly bodies...except for the sun due to vaporizing. If the moon was really created in the way that is commonly accepted...then the earth and the moon are made(formed) from the same material. If that event happened...then I can't see how some mass couldn't have been flung out in all directions and impacting or at least aimed to impact every other major body in the solar system...except jupiter or maybe Saturn. But then again if jupiter has played such a vital role in allowing life to be formed here on earth due to gravity protection...maybe that prevented this from happening. Good question and great mind exercise! Very interesting stuff!

@@jeremygalloway1348 I'm not sure what amount of intact meteorites the Theia impact would have produced since the newer models indicate the impact was likely much more direct resulting in the proto Earth's crust and much of it's mantle were likely vaporized as the Earth Theia impact remnant body would have been a disk of rock vapor rotating too quickly to coalesce into a single oblate spheroid body labeled a synestia. Of course it also seems that possibly at least 1 to 3 major chunks to Theia may have survived one of which likely seeded the precipitation of the Moon and if they are Theia remnants the other two could potentially be the origin of all or most of the low shear velocity anomalies found at Earth's core mantle boundary. The latter idea is still controversial with the other theory for their origin suggesting they are instead seafloor slab graveyards however both models have some evidence in favor of them the argument for Theia is supported by the amount of material matching the amount of material from Theia that had been unaccounted for and there is evidence for downwelling seafloor slabs sinking at about 10 cm a year and are recognizable as sunken seafloor crust dating back to the Jurassic. That said the low shear velocity anomalies are down far enough that we don't have as good of resolution via seismic tomography down there as we do for the sinking slabs from the Jurassic and Cretaceous. Now the hypothesis that Jupiter protects Earth from impacts has long been assumed to be true but computational models find it doesn't really hold weight as while Jupiter does prevent some comets which would otherwise hit the Earth from hitting the Earth it more than compensates that benefit by sending asteroids towards the Earth ultimately increasing the odds of an impact rather than reducing them. Of course without Jupiter flinging material into the inner solar system Earth might not have been the habitable world we know. As for impacts on planets Jupiter and Saturn are hit by impacts they just don't leave long lasting craters though the atmospheric scars can be surprisingly long lasting given the sheer scale of those planets. Calisto however does carry a long crater record so might be a good place to look. The other moons particularly Io and Europa have been geologically resurfaced much too frequently for anything to survive especially in the case of Io which has no craters just calderas from the extreme constant volcanic activity and vast mountain ranges from the continuous mountain building.

I was aiming more for mass extinction events linked to asteroid impacts. There is probably a limit of the energy transfered to the ejected material (above which it will just evaporate). Ejecta from celestial bodies above a certain mass and with a certain atmosphere thickness might not be able to leave the gravity well of the body. That is probably the reason there haven't been any Venus meteorites yet. The question is: could there be Earth meteorites on the Moon, maybe from an impact 33 million or 66 million years ago or is Earth's gravity and atmosphere too much of a hindrance for material to escape?

Uh

Hmmmm… Would that mean we could potentially extract samples of martian air from the pockets?

@@zerg9523 just watch the video.

The famous meteorite was the elagabal-omphalos, which became central to many religions. It was the omphalos of Delphi in Greece. It went to Persia in the 3rd century BC Then it cam back to Syria and was known as the elagabal (mountain of god). Where it was always embossed with the Phoenix - the fiery bird from space. Then Emperor Elagabalus took it to Rome. The religion it created became Sol Invictus, but the meteorite itself went missing. The Knights Templar claimed to have discovered it, and called it the Holy Grail. But the rock itself is still missing. Although Scottish Templars still claim they have it. It was wondrous and venerated, because it was highly magnetic. Which made it very exotic. R

"Confirmation?" What do you mean, confirmation? "Scientists" already know definitively - What good would "confirmation" do science? They know all! They can do no wrong, or publish no wrong! Listen to yourselves, people. Use common sense. If something must be confirmed to be true, it is merely a hypothesis to begin with! Which invalidates all of this so-called "scientific consensus" that some specific meteorites are actually "pieces of Mars."

That thin atmosphere & lower gravity REALLY changes the maths. Can't really "air brake", that much I know.

@@MikinessAnalog If all else fails. you can always resort to lithobraking, like the Mars Climate Orbiter!

@@coenogo I know, jus sayn air braking isn't really a significant way to slow down there. That retro rocket lowering an apparatus was genius, because it flies away after to crash elsewhere.

@@coenogo I see what you did there xD

@@MikinessAnalog You use a big, BIG parachute for part of the descent, but the last bit is a challenge. You can do some kind of rocket landing, with or without a skycrane, or the kind of bouncy-airbag approach that Pathfinder, Spirit and Opportunity used (and Beagle 2--I guess that part at least worked).

Yes Yes and YES!

They just ported my ksp mod to sr2 :)

hahahahahhaha i remember that

Yes. This was my question. Might we find bits of the Yucatan on Mars?

Imagine sending a rover all the way to Mars only to accidentally sample a bit of an earth meteorite.

@@peterjames808 imagine sending a rover to Mars and discovering fossils that just were ejected from Earth. Or perhaps it's the other way around :)

Theoretically possible but pretty unlikely. Earth has much deeper gravity well and much much denser atmosphere.

@@AldorEricsson Plus another variable to look at: Most of the solar systems mass is on the "Venus side" of Earth & to have a projectile from Earth go to Mars would take some serious speed.

Thanks. Tell that to the numpties commenting here...

I thought there was something wrong when he said that. Thanks for the clarification.

Probably got recorded yesterday or earlier

We’re pretty sure that core sample is from mars. /s

@@Keithustus this rule is kinda ambiguous

"OH NO! YOU CAN'T USE 'carbon' DATING FOR THAT!" Say the creatards. Just hope one will pop up here...

"Probably" Probably not.

Let’s hope we don’t seed Mars with OUR microbes.

@@clayz1 Yeah we should. Expand life beyond earth.

Bringing rock back from Mars (for anything other than science), is the economic equivalent of building a high speed rail system all the way around the Earth to take you from your front porch to your back porch.

@@Bear-form My point is that when we do find life on Mars, how do we know for sure it’s part of Mars for eons, and not just something we brought up there recently.

Out of this world.

"Hey, It's Fran ... in the lab ... again" XD

I believed this bs for over 55 years, but now I know it's all fake. We are looking at ANIMATIONs, so this is NOT REAL! ! ! 💩

I got to touch Mars once; the benefits of knowing a Meteorite collector. Amazing! I believe that at the Smithsonian you can touch a piece of Mars that landed in Egypt in 1911.

It got it already.

In truth, not many because Earth has a much higher escape velocity than Mars. However, it would be rather ironic if Perseverance picked up a sample of one, and it were eventually returned home.

Congrats! It's so surreal to hold not even a meteorite but a piece of another world in your hand. I have small pieces of NWA-11288 and NWA-11474 (Martian and Lunar). I wonder if someday someone will find a lunar or martian meteorite somewhere besides Africa and Antarctica? Surely they exist everywhere, just very difficult to find.

Space is- No, No I can't do it. Not even as a joke. Space is awesome.

yeah, we all know the vikings were everywhere, long before anyone else.

no

@@Q_QQ_Q you don't want to live on mars

@JZ's Best Friend its all for free money for corporate . none is going to mars .

@JZ's Best Friend its now financialization of public assets meaning we are creating anything new but finanializing already existing public wealth aka govt property like NASA etc by creating private industry out of NASA which literally means transfer of public wealth to corporate . though technically anyone is allowed but you know its just loot of public wealth . they are not printing trillions for nothing aka organized loot and plunder of public wealth .
