Another excellent update on the first few looks at the Bright Angel rocks. The long drive was worth it, as they hoped. Thanks for taking the time to find the historical geology papers on the “beef” in rocks. I never heard about that in my degree in geology.
Thanks. And yeah, "beef" was a new one for me. The latest WATSON images show detrital grains and no fibrous texture, so these veins may not qualify as beef. Stay tuned.
Bacon and now beef. Two of my favorites. Yes, I'm an omnivore. I feel like I'm not supposed to admit that nowadays, but I am what I am. Anyway, I'm loving Mars more and more. Didn't think that was possible! Thank you Mars Guy, for being here on Sundays. Makes my Sunday coffee and black raspberry filled donut taste infinitly better. :)
Thank you for educating this old man of 62. I wish that every teacher would encourage students to 'learn by observation' and give serious thought to 'interpretation' that doesn't just follow along with the latest, tenured 'fad'. Science should NEVER stop growing, NEVER stop learning and NEVER tolerate tenured idiots intent on preserving their pet theories. Let's ALL LEARN, shall we? (Yes - that includes you, Mr/Mz Tenured Knucklehead.)
@@oberonpanopticon blue is a result of oxygen in our atmosphere and any blue in mars atmosphere is a result of sunset. But I'm really not sure what a thicker CO2 atmosphere would do for color. Maybe deeper grey? Silverish to light purple maybe but I'm just guessing based on what we already see
This was the meatiest episode yet LOL :) All seriousness aside, could you do a future episode with more details and examples of those veins on earth? What kind of organic material has been preserved? I know not to expect fossils :) but I am just fascinated by these veins. Thank you so much....AND how did that layer get buried? More please
So, if the beef was buried and is now exposed, does that imply that there was a significant volume of water there, like a lake or sea, that deposited the beef and its veins? Then, as the water evaporated, it caused a flow channel into Jezero, which deposited riverbed material on it? Then, when the water was gone, the beef was exposed by erosion? If any of that makes sense!🤷
One scenario is that the rocks of Bright Angel were deposited in an earlier version of the lake and then buried by volcanic ash flow deposits. They may have then been fractured by the overburden, ultimately leading to mineral veins.
That's very exciting news, about the beef strips that might contain fossils. If we ever saw a clear imprint of a fossilized animal on a Mars rock would the first assumption be that it had been blasted their from earth by an impact?
Holly cow Mars Guy! Sorry, couldn't resist the pun, for such a profound discovery. Read "beef and cone-in-cone (B-CIC) fibrous calcite cements were precipitated contemporaneously just below the sea floor in unconsolidated sediment, in limestones associated with the end-Permian (P/T) and end-Triassic (T/J) mass extinctions." Can't post a link, but the quoted source should reveal itself in search results. The topic of B-CIC formation is a fascinating one, as even on Earth their formation in some regions lacks a definitive conclusion. This lead to my reading on the fascinating topic of biomineralization triggered by bacteria and "calcite moonmilk is the only known carbonate speleothem on Earth with undoubted biogenic origin, thus representing a robust and credible biosignature of life." Perhaps Bright Angel is remnants of leached moonmilk. Learning about both beef and moonmilk as a result of this episode is a profound coincidence. Can see why scientists are so zealous to get Mars samples into a lab to study in-depth.
The area to the west of Weymouth and Portland in the UK is known as ‘The Jurassic Coast’. A lot of soft mudstones and similar and very rich in fossils … as in people often walk the beaches and come back with all kinds of fossil, so very interesting to see these references to these rocks on Mars
😆Reminds me of the phrase "Where's the beef"?.............hmmm think they found it?! You've made some people wanna put some beef on the barbie today, thanks Mr Mars!!
would anyone know of any other science news channels? space, biology, antrhopology, etc. i used to watch scishow growing up but since hank and john green refused to properly acknowledge palestine and did not hold their community accountable for the hateful rhetoric going around ive had to find other sources. im currently watching anton petrov who does an amazing job explaining more indepth papers on space and some biology, highly reccomeded!
Yes, it's commonly done. It's called white balancing. The "enhanced color" versions of Mastcam-Z images essentially are white balanced: mastcamz.asu.edu/mars-images/images-videos/
Notice the craters all over the place just like the Moon. Because Mars doesn't have an atmosphere just like the Moon. Just barely 2% of Earth's atmosphere. You messed up you should have photoshopped some little wispy clouds.
When will NASA (and you) accept the fact that there never was a lake in Jezero Crater, and water never flowed through that channel? Liquid water on the surface of mars would quickly boil, freeze over, and sublimate. Flowing *water* would not have carried those large angular rocks that dominate the landscape. What eroded that channel and deposited that delta into the crater must have been a series of lahars -- violent flows of mud, erupting from the fissures upstream of that channel, carrying rocks for a short while and dying out in the delta. The mud would be the result of partial melting and boiling of deep permafrost by magma intrusions. After each eruption the mud quickly froze and its water content sublimated, leaving behind a layer or dirt, rock, and dissolved salts.
As verified by the MAVEN mission, Mars had a much thicker atmosphere after it formed, which was lost to sputtering over billions of years. Liquid water flowed on Mars early in its history and contributed to water-bearing and water-formed minerals.
@@MarsGuy Wikipedia says that it is a *conjecture* and the atmosphere must have been lost over millions of years, not billions. If it happened at all, it must have been *long* before Jezero crater and its delta were formed. It there was rain at this time, Curiosity should have seen signs of it. If there was no rain, how would the "river" and "lake" form?
So, this beef strip returns to Earth from Mars, in what six to ten years, what's the price per pound (or is it better to return to thinking pork bellies and ask for future contract pricing)?

"nothing useful will be learnt" - oh my god - there is a non-neglectable probability, that these veins may inhabit the secrets of life (and if not, than at least the secrets of geology) in ancient Martian rivers - and @glennbabic5954 tells us there is nothing useful to learn. Mars can tell us so much about the history of our Sun System and the future of our planet and the worst case results of climate change. The pure knowledge and certainty , that mars once was a humid planet covered more than a half by an ancient ocean is worth every cent we spent for exploring that planet.
Loving the added humor, thanks Marsguy Forscale.
This comment has been nominated for winner of June 2024
I love that beef vs. bacon humor.
Glad my humor is appreciated!
The distance and terrain the rover covered is mind blowing.
That's what I always marvel at too, I can't believe it's traversed through this much terrain in just under 1200 sols...
Keeps getting better and better, thanks for sharing. Charles
Thanks, glad you think so.
The Mars meat lore is expanding
I can't overstate how much I love this channel. Thank you!
Glad you do, thanks!
👍🏻 Thank you Mars Guy. I appreciate your Sunday updates and explanations. Thanks for taking the time for us.
Thanks as always for watching.
Mars is a very interesting planet. It could be billions of years older than we thought. Leaching of minerals takes a long time. Thank you MG.
Glad you're interested!
So the exploration and insights continue. Fascinating stuff MG. JPM ⛏️🇬🇧👍😎
Thanks as always and more to come.
What a spectacularly different marscape - thanks!
Glad you think so!
I am vegetarian but I approve this message.
Same, but never to early to start thinking about Mars restaurant ideas 💡😋
Perhaps Mars Bacos would be a better fit?
@@EdmundWChan As cheesy as it is, I bet people would like a potato restaurant with little Sojourner rover replicas as waiters.
"No, not these guys" 😂😂😂
Can always trust this channel to give me my weekly dose of dad joke

You can say whatever you want. People are always going to be assholes.
That donut sounds great!
So much to absorb ❤
Nice line to end the show
Great stuff as usual - thanks for the updates 👍
Thanks as usual for watching.
Thank you for the insert of "Quarrymen."
Couldn't resist!
If the Quarrymen are even slightly associated with Mars exploration, then I predict that they will do well.
Ha ha!
Fascinating, once again!
Great, thanks!
very good Thx Mars Guy !
interesting as always - thanks. nice touch working in the lads from Liverpool
Glad you liked it. I couldn't resist!

I wonder what the sky on Mars would have look like when the atmosphere was thicker and had much more water vapor content. Redder?
The red colour comes from the dust in the air, so probably bluer, or at least white
@@oberonpanopticon blue is a result of oxygen in our atmosphere and any blue in mars atmosphere is a result of sunset. But I'm really not sure what a thicker CO2 atmosphere would do for color. Maybe deeper grey? Silverish to light purple maybe but I'm just guessing based on what we already see
I should have known of the Quarrymen before they once more changed their name but we had somewhat restricted listening rules.
Ha ha!

Ha ha! I'll probably add more details as more work is done on this rock.
Awesome :) thank you!
Wow - even Perseverance is going carnivore! Incredible!
We really need to get human scientists out there to confirm once and for all that life is a matter of science, and not teligion.
2:03 there is something in the sky above the red arrow.
Speck of dust on the camera?
4:03 @RealCivilEngineerGaming you doing the driving?!
I came here salivatin for a real meat planet dadgummit
Electrically deposited veins then.
Thx, Mars Guy. What a great exploration to be a part of!
BTW, if you come across a good marbled ribeye, lemme know... 😊
Ha, good one!
Fascinating, thanks for the video.
Thanks for watching.
Mars Guy making me want to get out the barbecue for dinner tonight 😂

Might go get myself a snack..... I'm hungry now.
At (3:13) for a nanosecond I freaked out thinking that was supposed to be Mars.
And then it was gone...
One can at least hope😎

At best there'd be microfossils.

Where's the beef? On Mars, apparently.
Are geologists and astronomers just always snacky when they name stuff?
Ha ha!
Great stuff...
But for some reason, I am now hankering a BLT or cheeseburger.
Ha ha!
what's next, lamb or chicken?
I would like to know your best guess on where all the water went and hiw to reverse a process like this
Evidence now shows that atmosphere was sputtered away and with it, most of the water.
Thank You Mars Guy!
So it is even better! Give me those samples:)
Agreed!
How did #carnivore bring me here... 🤣🤣🤣 👍👍

Better than bacon? Bold claim 😂

Nice to get commentary.
Bacon is 72% fat and salty. Me too bacon, me too...

I’m getting hungry!
as good, informative and entertaining as every week - what else do I have to say - so keep that fire burning (just to post some music quotes too :-) )
Thanks for the encouragement!
Better than bacon!
So, "Bright Angel" is more of a NY Strip than a Bacon Strip 🤔
I guess I have no beef with that. 🙂
Ooh, good one!
Bacon or Pork Sausage🤣
Bacon, beef can we have a veggie meal please Mars Dude? TFS, GB :)
Ha, no, not this time!
And now I’m hungry. Mars beef may be better than mars bacon. 🤣😋
That is not beef veins, I recognize that from eating a UK restaurant, it was served with haggis and mushy peas.😮
One could say "The burgers are better on Hungry Mars". Maybe only Aussies will get that one.
Awesome 😂
Now if we could find egg crator we would have it made
Thanks Mars Guy, where's the beef? Funny how that name was used in the 19th century 🙂
Cheers 👍💪✌
Yeah, and here it is still in use!
We have the meats!
