I don't comment often but I just wanted to say thank you for these videos. It's so nice to be able to catch your five minute updates every Sunday and keep up with the progress of these rover missions. In the hustle and bustle of everyday life it's easy to forget that there's some VW Beetle sized rovers doing cool stuff on Mars,, but with your videos we all get to follow along without having to dig for info. It's a real public service.
I just love these unforeseen discoveries that space science brings to the table. It's exactly where science is so brilliant. Thanks Mars Guy for your insight and videos you bring us. Cheers 👍💪✌
thanks for earth family for scale! The columns in Arizona look like something we'd make in our sandbox with wet sand by dribbling it in one place in stages to build up columns.
So much geology in one place!!! Volcanoes, rivers, lakes, meteors craters, erosion...my head is happily exploding! Thank you for the deep dive into the olivine crystals.
Thank you, Mars Guy. My Sunday morning coffee tastes so much better thanks to your videos. You've made geology on Mars AND Earth, fascinating to me. I wish I had developed this interest 5 decades ago. But no matter, I'm loving it now because of you and this channel. I have started to look at rocks the way a book lover looks at books in a library, every rock and pebble has a history and a story to tell!! True, I can not read those stories, but just knowing they have one makes me see them with a new found appreciation and admiration. BTW, can you recommend a book on basic geology for a mind with a high school education and a newly found interest in the field?
So nice to know that Mars Guy content has inspired you in this way! Thanks for sharing your new found interest. I'm afraid I don't have a go-to book though. But a quick search on "introduction to geology book" returned a lot of options.
Does this latest discovery invalidate the accepted understanding of the olivine origin shown in that paper? Or does it still make just as much sense or slightly adjust it?
Thx, Mars Guy! I visited the Papakōlea Green Sand Beach Hawai'i a few years ago, which got me reading about it. It also has those "bands" (or layers?) like the area in your video, and is considered a tuff ring. 🤔 Do you think there's any similarity? One fact I don't know is the % of olivine @ Papakōlea. Not sure if as high as 25%.
What an achievement by Perseverance, to finally reach the top of that steep slope. Next stop, Lookout Hill. It's very fitting that an alien planet gives non-Earth like formations. Got to keep the scientific community on their toes! After billions of years, who could say that a strong Mars earthquake, didn't knock those rocks over? Looking forward to the 191st episode. Kiwi David (The only rocks i've studied, are the ones in my head)
I wonder if it's possible the olivine could have been inserted and distributed by the meteor that created the crater? The Tuff that apparently forms the ledges around it may be the fall back of the pyroclastic flow the meteor would have created...?
Love the geology perspective. So much Mars geologic history and formation processes can be derived from the rocks. What’s your opinion on which way to invest in Mars R&D money; 1… return samples or 2… a more complete lab on Mars? Also what would be included in a more complete lab on Mars? (Isotope ratios of crystal grains? Age dating via zircons? Mass spectrometry for isotopes and element ratios in grain sized samples? Stereoscopic 3D analysis of grain structure? Hyperspectral measurements & analysis? Electron microscope?). I have doubts about ever getting our hands on the collected samples due to cost and think a more useful goal would have been planting seismometers all over the place instead, or an improved lab.
I've been an advocate for sample return. Certainly more can be done in situ, but I think the opportunity for breakthrough science will come from the kinds of analyses that can only be done in labs on Earth.
These pictures look almost identical to Devon Island, but of course it can’t be because Devon Island doesn’t have a red tint as we can clearly see these pictures do.
Glad you liked it. I was trying to make the point that the original hypothesis for the origin of the Seitah terrain as an "olivine cumulate" may be wrong, but still have a volcanic origin.
The irregular banding in the rocks is due to erosion; The rocks that lie incongruent to the banding eroded earlier, and have fallen down over the ages, as the soil which encased them eroded away. That's the only reason there are many rocks there that appear incongruent to the neatly layered rocks that are embedded in the soil. It's easy to build scientific opinion like a house of cards by failing to consider certain facts.

You're right!! I hadn't thought of that. Although I have heard of caves being formed by a large decaying biomass of some kind like a large animal. I have never looked that up to confirm whether it's BS or not.
Devon Island. They posted an image with an arctic lemming. A lot of these photos were faked Photoshop color. Correction also identifies the photos is being altered.
What you are seeing lying around on the surface of Mars is Cosmic dust. The real Martian rock is tens to hundreds of meters down below. On earth this cosmic dust is swept away by rain to the sea. On Mars it just sits there, hardens and become stone hard rock.
If they ever found something like the Sailing stones of the Death Valley people would loose their minds and the conspiracy theorist would be out in droves. Would be entertaining.
They will be all talking about that rock with the 90°ish angle. There was obviously an ancient advanced Martian race who built that... pyramid, wall, Atlantis....
Geology is a science. Not an exact science (it's in the "stamp collecting" category), but a science nonetheless. I don't know why anyone pays attention to Chuck Lorre at all.
@@MarsGuy Professor Mars :: thank-you! for the word "Areology" -- every time I heard "Geology" applied to other planets or moons it kind of grated on my ears.

@@ukraine7249 I have been following SpaceX's Starship System development, since Starhopper. Your jumping the gun a bit. There has to be the 'Tanker' fleet built and a testing of Starship to Starship fuel transfer whilst in orbit, before a flight to Mars can be made. The 'window to Mars' is November-December 2024, which obviously is going to be missed, so the next 'window to Mars' is not until January-February 2027. So I have to give you the bad news, that your 2026 time frame, is not possible.
Are we to call Olympus Mons "Pure-Foot Mountain" as that's what most historians agree the term Olympos originally meant? You're more than welcome to selectively translate the literal meanings from the names you don't like as you see fit, but there's not much point. Séítah is more than fine. If we did the same for Jezero Crater it would translate to "Lake Crater".
Seitah. Like Google, Chrome, Crypto, TikTok, Amazon, PayPal, OpenAI, Vestis, Summit, Zenith, Oracle, Apollo, Sirius, Gemini, Delphi, Saturn, Israel, and many many others all have something very simple in common that is esoteric in nature and hidden in plain sight. Anyone willing to guess what and why?
I know this is going to sound harsh, but your speech cadence and unnecessary inflections make the video hard to listen to. For example 1:10 There was indeed a lot of olivine in these ROCKS... But... It appeared to have formed...innn an unexpected WAY... Your voice inflects on ROCKS and WAY.
Thanks!
Thanks again for your generous and regular support of this channel! It sure is nice to have viewers who are so appreciative of this content.
4:26 “Here’s Earth Family for Scale” Thanks for the chuckle. Love your sense of humour. And thanks for the Mars updates too, the reason Im watching.
Glad you were amused, and glad to have you watching.
I was here to mention this one! 😂 Cheers!
Thanks again Mars Guy. It's quite amazing that you can give us weekly updates on Mars exploration.
Happy to have viewers who appreciate this.

Keep it up. 👍🏻
Thanks, glad you enjoy them!
Great video as always. My little Sunday ritual.
Thanks, glad to be part of it.

Glad you're a fan of science and this channel.
Yay. Sunday AM and time for my Mars update.
If someone had told me 20 years ago: "One day, you'll check every Sunday what's happening on Mars," I would have thought they were crazy!
thanks for earth family for scale! The columns in Arizona look like something we'd make in our sandbox with wet sand by dribbling it in one place in stages to build up columns.
Ha, they do look a bit like that!
The images of Mars have always given me the impression of a "shattered" surface.
I love this channel. I'm so glad I've been alive long enough to see Mars in such detail.
I'm so glad you're enjoying it!

Another fantastic MG video. The hoodoos at the end reminded me of similar formations in Cappadocia Turkey 🇹🇷
Ah, that's a place I'd like to see in person. The geology is similar.
Could all of these not be decompression joints formed subparallel to the surface by removal of the overlying rocks by erosion?
Does this latest discovery invalidate the accepted understanding of the olivine origin shown in that paper? Or does it still make just as much sense or slightly adjust it?
Too strong to say "invalidate", but it could challenge it.
"Here's family for scale" 😆
Another great lesson in geology and another bucket list place to visit in AZ!
Glad you were amused by the family and amazed by the AZ geology.
Can you imagine a more water eroded Mars with hoodoos? I guess well just have to be happy with the weird discoveries we are actually finding.
Good morning MG that’s a lot of erosion. Thank you once again for your work
Thanks again for watching.
Maybe olivine doesn't separate as much in lower gravity?
Great observation.
This was great--as usual. Thx!
Thanks, glad you liked it.
Rite Dr Mars Dude, Hopefully feet will be on the surface in the not to distant future! TFS for Episode 190, GB :)
Hope we live to see that happen!
So enjoy the Mars Guy perspective on Perseverance's geographical observations. The added scientific context is so educational and informative.
So glad to have such appreciative viewers. Thanks again for your comments.
What a find! Why didn’t UA-cam recommend this channel sooner?
Glad you found it. Welcome aboard!

Tuff rings can show layering, but not such abundant olivine. It gets concentrated in the beach sand there.
@MarsGuy thank you! 😎
*LOL Earth Family for Scale haha very good.*
Glad you're amused!
Ignimbrites are some of my favorite rocks. The ones on Earth are not full of olivine, though.
Amazing
The mars guy for scale thing was amazing.
Thanks, glad you thought so.
Thank you Mars Guy for the amazing update! I think its better to put you on bell notification.
Thanks for your interest!
never seen pictures of Chiricahua b4. think I mght go there sometime

The regional distribution of abundant olivine well beyond the crater and its ejecta is inconsistent with an impact origin.
Outstanding information and detail. Thanks Mars Guy.

@ thanks for responding. What kinds of analysis can be done only here that can not be done by sending an upgraded remotely operated lab to Mars?
Geology of Mars
Interesting
As Comparable to Earth
Olivine is one of the most common rock minerals on earth. If its the same on Mars, no one should be surprised.
It's good to see exogeology taking strides forward. There's a big science payoff from this mission.
"Earth Family" Why is no one talking about this HUGE discovery?!
HI EARTH FAMILY!! 👋
