Scientists think that the oldest rocks in Jezero crater formed from a thick lava flow or lava lake that once filled the crater. Now a very similar rock appears to have washed in from outside the crater, challenging that idea. - Věda a technologie
Thanks!
Your regular support of this channel shows that you’re a true patron. Thanks for that!
Blows my mind that we're seeing these zoomed-in glinting rainbow effects from facets of rock.... ON THE PLANET MARS
It is a bit surreal.
@@MarsGuyyes I agree surreal 👍👍👍
Is a digital rendering of someone's imagination.

You're not, but NASA is.
CGI garbage is NOT a photograph.
Another GREAT video! I never fail to learn something from your videos. Which is why I think they should be shown in science classrooms everywhere. Thank you again, Mars Guy.
Agree
This channel is criminally under-subscribed. Share these with everyone you know.
Thanks for these encouraging comments.
Another week, another great video.
This does tickle any geologists mind for sure.
My ex wife was a geologist, she surely would like this channel.
👍💪✌
Glad you can appreciate a bit of geological intrigue.
Great again as usual. This channel is really underrated and deserves more subscribers.
Thanks for being one of them!
The size-scale images were very helpful. Thank you.
Agreed.
Thanks, glad you appreciate this.
Thanks for sharing, one more thing I didnt know yesterday. Cool! Charles
Happy to share!
Additional units of scale are a great contribution to getting a handle on the landscape, as well as keeping us on our toes. Thanks for such creative explanations. In-depth geology is also always welcome.
Great, thanks! Glad you appreciate the geologic content.
Another great update. It's the discovery of these geological "anomalies" that reminds us of why we need rovers and eventually humans on Mars. Many thanks for the explanation. Fascinating.
So glad to have your continued support and interest in this content. It's encouraging feedback to keep producing more. Thanks!
Came here for the helicopter, ended up with the rocks as Mars Guy goes full on geologist. Actually a good thing as I learned a lot, helped by several replays!
Ha, glad you stayed! Thanks for the comment.
Yay volcano time 😂 (whistles nonchalantly) well this is a happy twist, but the jury is still out until percerverance gets a bit higher up I guess. Nice abrade though👍 who knows,maybe a honking great Mars mantle xenolith will turn up in the wash, wouldn't that be something 😄 still the apparent similarity to the rocks in seitah is interesting. I guess we'll have to wait and see. Great video Mars guy👍🙋
Thanks. Yeah, this will be a fun investigation to follow along with. Probably no xenoliths though!
Mars is such a big puzzle of rocks, and what we (humans) know of Mars is just a small sampling of it's surface. These insights from Mars Guy show us just how much we have learned and are learning about Mars. At the same time, highlight how much more we don't know of Mars and it's history. This 5 minute lesson was so cram-packed with concise and interesting science.
True about our limited knowledge of Mars, but it's definitely expanding. Glad you appreciate learning about it.
great use of google earth mars guy! as always your videos are very informative and interesting! thank you sir!
Thanks for saying so and thanks to Google Earth!
What an elegant, simple diagnostic: to have lights on both sides that could be turned on separately or together!
I know, right!
Think it’s time we sent Mars Guy there to find out what really happened😎, excellent episode Mars Guy👩🚀
I'm ready to go!
Appreciate your in-depth reports thank you
Great, thanks for the comment.
A true mystery. Percy and Ginny are only going to be able to scratch the surface both figuratively and literally 🙂 Thanks again Dr Ruff 👍
Thanks again for watching. Exploration like this is indeed a detective story.
@@MarsGuy Ah, but Watson the game is afoot 😄
@@thatotherguy7596 Nice! Hope that also was a reference to the WATSON camera.
🔍 📷 🙂
An excellent episode once again. Solid science.
Thanks for that.
Amazing reports😊
Thanks!
Mars guy does not waste a single word. You have to listen carefully to every single word or critical information gets missed.
I do try to pack in a lot of information. Glad you appreciate it.
Another fantastic episode. The size references are doing wonders for the presentations.
Thanks, glad you think so.
Another mistery to solve. I love it!
Yep!
Would the olivine mineral be a good resource for making Lithium Iron Phosphate batteries?
What interesting geological exploration opportunities we have there, rocks in states that would probably be hidden or altered by life, but left to hardly change at all on Mars.
True!
Thank you Mars Guy. 👍🏻
Thanks for watching.
Good video. Your superposition of common terrestrial objects to give us a sense of scale is outstanding. Thank you so much.
Thanks, glad you appreciate this approach.
An other awesome video 👍👍👍
Thanks, glad you think so.
Fascinating!
Your awesome bro, keep it up, here is a token of my respect for the time your take to make your videos so perfect
Thanks, I really appreciate that and your comment. Nice to know people are noticing.
Cool. Fascinating
"Land of Odds"...I see what you did there. LOL. Another very interesting post. I'm going with the boulder being brought in by a flooding river. Thanks again for keeping us informed in such a interesting and humorous way.
Glad you got that! I favor the floodwater emplacement hypothesis of the boulder, but impact emplacement can't be ruled out yet.
Great vid 👍👍👍 a mystery
Thanks for watching!
"Strangely familiar" rocks could get this video de-monitized. Small price to pay for the public exposure of science, I suppose.
Bravo! It's probably good that that was not the moment the customary "here's Mars Guy for scale" motif was used...
@@paulmeahan3667 HA!
Ha, good humor!
Thanks for showing my home island 💜 being on top of Lady Etna feels like another world... Especially when space agencies come there to test their rovers on volcanic terrain, like they did a year ago 😁
Wow, cool! Thanks for sharing that.
😊
Just stumbled on your channel...
Finally, actual geological detective work from the rovers
It will be sifting through your stuff
Glad you appreciate this content. Welcome aboard!
Thanks, MarsGuy, I feel my IQ has increased after watching your videos!❤
Ha, happy to help!
Excellent and wonderful every video Mars Guy, your genius is infinite, big hug and a big greeting to all your great community!🌟
You're too kind! Thanks.
Always riveting. I especially love you don't display scale by US or Metric, but with Mars Guys.
Thanks, glad you appreciate the relatable scale bars.
Yess, don't mock the rocks, the stories they can tell, how exciting!! Great video, again, Mr Mars, thanks for sharing!!
Ha, no mockery intended! Just enjoying some pareidolia.
You really do a phenomenal job at explaining and elaborating the subject matter and informing all of us.
Thanks for the encouraging comment.
Great tip! I agree I easily overlooked this!
Curiouser and curiouser! So, the Jezero story has several subplots.
Indeed!
Can you put the literature reference in the description?
How about here: www.science.org/doi/10.1126/science.abo2756
Thank you for depicting the scale. You are the only one I've ever seen do this.
Glad you appreciate this approach. Thanks for the comment.
Mars scientist Larry Crumpler calls it Coyote Mars :-) Thanx for this very interesting video. Is there an assumption about the origin of the irregular shapes of the rocks in that area? And before the abrasion process we saw the crystalline crust of this rock - was this a crust of pure brown olivine?
They've been finding wind-scoured bizarre looking rocks that nobody has ever seen before. It's due to the much different atmosphere which causes unique wind erosion.
I'm not sure what's going on the natural surface, but my guess is there may be a coating eroding off. I know Larry from our days on the MER mission. Not sure what Coyote Mars refers to.
@@MarsGuy I'm actually reading Larrys Book "Missions to Mars". There he talks about "Coyote Mars", because Mars tricked scientists and explorers so often in the history of mars exploration.
@@MarsGuy Coyote Mars red glaze - Used when making pottery. When fired in a regular cycle, the Mars Red Iron is a deep brownish red, similar to Saturated Iron.
@@drguenther OK thanks for the clarification.
Which of us older folks would have ever imagined, as our generation revved up for exploring the frontier of outer space, that good-old-fashioned geology would play such an important role?
Get out your hand lens!
Thanks!
Thanks so much for your show of support for this channel. It's much appreciated and encouraging.
I'd be a lot more excited if not perplexed if that boulder was actual in-place outcrop. Way back when, I was taught to be skeptical of boulders lying around since they could have been transported from darn near anywhere by any means. When talking about volcanics and lava flows, anything is possible. I like the ejected boulder bedrock from the bottom of Belva crater theory.
That boulder clearly was transported in, but whether through the air from the Belva impact or via floodwaters is to me an open question. Both have scientific merit.
Very interesting Mars Guy! thanks..
Thanks, glad you think so!
0:08 How could the oldest rocks in the crater be from the lava flow that once filled it? Wouldn't the rocks that form the actual crater itself be older than anything that then later filled it?
Yes, the rocks that preceded the formation of the crater are older, but they're buried by crater fill.
Wow that is cool that you have a rock from the Earth's mantle. Is this from a lava flow? Also how does one determine that it is from the mantle?
Yes, mantle xenoliths come to the surface stuck in lava. Only the mantle has such concentration of olivine.
So is that going to be the parking garage area for the strip mall?
WOW!
What maps are you using to navigate these images. Are there ones for the Moon, Mars, etc. like google Earth? Pretty incredible.
mars.nasa.gov/mars2020/mission/where-is-the-rover/
@@MarsGuy Awesome Thanks!
I've noticed that all of those rocks have the same small disc shape cut out of them! Is that part of the asteroids impact?
I was watching the new eruption in Iceland the other day and the river of lava it created could easily be said to be created by water. Looks just like a lot of these 'rivers' on Mars.
They have found evidence of mud volcano eruptions - any chance the river channel was carved out by a volcanic mud flow?
What the lava river in Iceland would do is it'd plug up and over flow the banks. It'd fan out and leave a very similar looking delta-like structure as seen here on Mars.
The fan deposit has no evidence for lava flows but lots of rounded cobbles and boulders, consistent with floodwaters.
I have watched your videos on and off for a while, but I finally subscribed due to your great content!
Very technical, but not stuffy explanations, and no little green men theories, which is great!
Thanks for this encouraging feedback and for subscribing. Welcome aboard!
The Land of Odds! 😂 love it. Thank you!
Glad you do!
Once I was able to visit the All American Canal. An area of the Colorado River waaay south before it enters Mexico. The place in question was sand, lots of sand. The canal was dug out from the sand. When I examined the rocks in the sand I was surprised to see that …Holy Cow… it was a mixed bag of rock types. Volcanic, sedimentary, metamorphic, fine grain, loose grain, etc. Makes sense. This was where the watershed of the river would have washed down the sand and rocks of its respective geological areas. From many miles away.
So that area mentioned at :30 reminds me of my time there.
Yep, rivers have a way of sampling and redepositing diverse rock types.
@@MarsGuy Looking back, I wished I had more time. A smorgasbord of interesting rocks. All neatly palm sized. Unfortunately I was working.
I really wish NASA would stop putting these red filters over Mars pictures, the actual pictures without the filters look surprisingly much more earth-like and beautiful.
Absurd
Id wonder if at some point that zone had glaciers moving out over the water and raining out stones, then at some point at the end of the glaciation a glacier lake ice dam finally collapsed flushed that river delta and the water on mars began to evaporate away as the planet changed.
So no water? Just lava?
New subscriber. Interesting mars guy. Thanks!
Thanks, welcome aboard!
What script?
great stuff as always
Thanks again!
The latter option, no doubt.
This seems like a very interesting and promising channel, so I've subscribed! 😁 I do like the fact that you contrast landscapes etc. with either Mars Guys or the Giza pyramids . . . but . . . @Mars Guy Yeah, but now we need to know the scale of the Mars Guy height/width/weight? 😁 You could be a midget or a giant for all we know! 🤣
Thanks, welcome aboard! Mars Guy is just average size on Earth.
Nice
SURE
You didn't mention two factors to consider about that rock, which are the depth that it did or did not penetrate the surface. If it is lying flat on the surface with no penetration then it did not get there by being ejected by explosive force somewhere else.
Also, if it had fallen from a considerable height then it would have fractured into pieces if the ground was hard. If it is not a badly fracture rock and it's not semi-buried in the surface, then it did not fall from any height.
That is so American. Take Navaho land from the Navaho, then name land on mars that the Navaho will never be allowed to own, using a Navaho name. "We did it to honour the Navaho people."
Or it was something that the Navajo Nation embraced and appreciated: mars.nasa.gov/news/8886/nasas-perseverance-mars-rover-mission-honors-navajo-language/
Yah! We (Our) so not Alone! ( Soul)
Meanwhile, back on earth, we can’t teach some people to throw their rubbish in a bin, or stop drinking too much alcohol…technology eh?
Can you please let me know if this is a US-made nasa. I wonder if my nasa works internally or is there an unrelated department that has a different certification or is it only Americans who can do it... ..n????????
Yes, this is a NASA mission.
so the crater might be a caldera?
that's what I was thinking
Jezero is certainly an impact crater, but there are candidate calderas outside of it.
@@MarsGuy Got it, Thanks Mars Guy
The only problem with the theory of washed in is it would have to go up hill. I could tell that it's uphill by dry river beds. So that theory is out. Now you're down to meteor impact. This is feasible if there is an impact near a deposit of Olivene. But than at the end you came up with a different theory of Volcanic explosion. I find this theory unplausible. It just doesn't look right. Obviously that Volcanic situation would have happened many years ago. It seems like it would be deeper in the sediment. But it looks like it's on the top. So if it was up to me I would say meteor impact.
"Washed in" means rocks from outside the crater (upstream) with the same composition that were delivered to the fan deposit by floods.
@MarsGuy but by the sediment flow, you can tell they would be going up hill. How does that work in the laws of physics?
@@johnrathbun2943 Sorry, I don't understand what you mean by sediment flow. Water flowed into the crater from the inlet channel to the west, carrying sediment from that direction.
why they do not go to the moon to make pictures ? there is nothing there to see ???????
Excellent informative narrative again! Thank you very much!
Thanks for saying so!
Rare to see videos like this without having to hear any evolutionary fiction! Thank you.
Yeah. Evolution deniers are rather daft.
Thanks for watching.
It blows my mind they're spending all this time and money learning about rocks on Mars. It doesn't benefit humankind at all. just scientific entertainment. The money and time should be spent solving problems on Earth.
What about nukes then
Ice comets
hmmm.... Jezero means "lake" in serbian , interesting
Geologist here. So there are erratics on Mars. Wake me up when you find something interesting.
No
This speculation is "stunning"? More like click bait.
There is no such thing as a "Mars rover". It's on Devon Island, here on earth.

If Mars has a thin atmosphere that acts like it’s over 100,000 feet altitude, then How could you slow the craft. A parachute would be useless. Even drones can’t go very high
Its going to have to be Rocket Engines.
@@dnomyarnostaw the CGI helicopter, and the CGI parachute, with inflatable landing gear. Devon island the mushrooms on Devon island, or the hiker with the blue winter coat in the background of the mars lander, On Devon island… or the matching mars landscape with the exact same background as Devon island. Come to think about it. I want my money back! They never went to mars
@9greatdanes981 oh you funny man thing.

I used to be keen about the discoveries made by Percy but imo there's little that's new and the publicity nowadays is just hype. The helicopter has been the most significant aspect of the mission. Pity about the ESA rover, maybe the Chinese will find some extinct or active biology.
Fake
Yeah. Space travel deniers are rather daft.
