I just want to say a big thank you for your amazing work! Your coverage of Mars topics is scientifically neutral, incredibly well-researched, and so fascinating to watch. The effort and quality you put into your channel are truly impressive. Honestly, a channel like yours doesn’t just deserve 40,000 subscribers - it deserves at least 4 million. Please keep up the fantastic work - you’re making a valuable contribution to science communication!
What a remarkable presentation showing similarities between Earth's and Mars' craters. The description of the crater formation physics is helpful to my understanding. Thank you Mars Guy and Team.
That opening sequence showing the rover's path and then zooming out to show the size of the crater was great! It really helped me to understand the scale of the crater. It's MUCH bigger than I had guessed.
Terrific production MG! Especially superimposing different craters on Earth, Moon and Mars, and the zoomed shots from Percy. It would be interesting to have more information on why ejecta on Mars could be a goldmine if brought back to Earth. Would it be the information that could be garnered about the asteroid or comet, or about the surface of Mars? Thank you!
Glad you appreciated the crater comparisons. Regarding a sample of impactite, it would contain bits of rock that formed before any of the rocks sampled by Perseverance inside the crater, so could shed light on the geologic history of the region prior to crater formation.
I look forward to your frequent Mars updates ! :-) Really well produced and easy to understand. I really feel included in the journey of the Mars Rover and its exploration. I only hope that you would get way more subscribers !!!! As you earn that and I hope your videos dont stop Thank you so much.
@@MarsGuy Note that at 01:56 the process can involve older strata contained in the ejrcta ending up overlaying younger strata surrounding the impact. That is what I was thinking of when I made that comment.
Good morning MG it’s great to be on the other side ,also that is a great example of how an impact crater is formed great work as always see you next week Rick NYC
One big thing I like about this channel: Usually no morons commenting "Fake!" and other idiocy. And forget about trying to watch anything good about ancient Egypt. Then again, I don't HAVE to read the comments but sometimes you can learn something there too. It's like wading through a cesspool of knowledge trying to avoid turds. 🤢
Rite Dr Mars Dude, There is a church just over the road from where I live (None believer) but @ 10:00 they ring the bells so from now on its gonna be my Mars Guy call! Stay safe n well Steve. TFS, GB :)
So happy Mars Guy made it to 2025! Just love this first video of the new year. The picture of the impact with "melted" rock pouring over the rim is indeed cataclysmic! Looking forward to my new year filled with Mars Guy videos :)
Since it's clear that running water was there after Jezero was formed, will Perseverance be able to show if running water was present at the time of the impact or did that come much later? Thanks again.
It's rock-hard to wrap my thinking around the suggestion we're looking at terrain created as-is Four Billion years ago -- generally unchanged since. As most of our geological examination is done on tbe Ever-Changing Earth-Surface. Four Billion Years ago Earth looked hella-different. ☆☆😊
Excellent explanation about large crater formation processes! I appreciate how much work it must be to put together these videos. The new moving Mars Guy for scale is amazing, but it must require substantial filming and editing effort.
Glad you appreciate and recognize the effort. Fortunately, I've been able to "recycle" green screen video recorded for the first episode. Still takes some editing though.
One of the only good things about the future is how we all casually look at pics from the surface of Mars like its no big deal. Like " More rocks! Neat!! "
The rover's SuperCam has captured detailed images of the rocky outcrop, revealing textures similar to impact heights found on Earth. This texture provides clues about Mars' geological past.
Always a terrific presentation! I'm starting to wonder whether it will be easier to bring the samples back to a laboratory, or bring a laboratory to the samples.
@@MarsGuy Thank you! I admit to being slightly facetious there. It's just that we've got so many samples now scattered all over the place, that the effort required to gather them all up and bring them back, is looking increasingly Herculean, (and expensive). I hope we can.
@davidwuhrer6704 The rover is cancelled, but in current plan ESA will make an orbiter to catch the sample in orbit and deliver it to Earth. Current plan for retrieving samples seems to be using Persaverence and maybe one or two helicopters(but there seems to be a landing mass issue).
Think it would be interesting to have a rover there that can dig down and the deeper the better. Would want to see what its like under the sand in some spots.
Question: What is the age distribution of the MAJOR meteorite impacts on Mars? What is the youngest major meteorite impact on Mars? (For Major, let's say one that left a crater of a 100 meters or more.)
Fine stuff. One minor observation: I have no idea what size that coin is. May I suggest a CR2023 battery, your trusty Swiss Army Knife, or - heaven forfend - some kind of ruler?
Sad that we now think in terms of "If returned to Earth". There may be hopeful news on that front in the coming days with the launch of Blue Origin's New Glenn rocket. Many hope that it will significantly reduce the cost of getting large payloads to Mars. Launching, of course, is only a portion of the cost, but it's a hopeful sign.
This planet is dead since then. No continental drift, no magnetic field, no significant erosion, altough it has atmosphere and winds. It would be a miracle if we find life there today. But that´s not the point...
A great way to begin a new chapter, with MarsGuy on the outside of a crater, looking back through time. What a timely update on the prospects of shipping a sample of impactive to Earth for analysis. btw: Hearing rummers of an update from NASA on its Mars Sample and Return mission this coming week.
Thanks!
Thanks for your generous show of support for this channel! It's encouraging and appreciated.

Thanks @t.d.5804 for your encouraging feedback. So glad you appreciate the work and I'm happy to have such supportive viewers.
Thanks Mars Guy for another awesome geology video.
Areology XD Geo means earth.
Thanks for watching.
What a remarkable presentation showing similarities between Earth's and Mars' craters. The description of the crater formation physics is helpful to my understanding. Thank you Mars Guy and Team.
Glad you appreciate the comparative planetology and a bit of physics.
That opening sequence showing the rover's path and then zooming out to show the size of the crater was great! It really helped me to understand the scale of the crater. It's MUCH bigger than I had guessed.
Thanks, glad you've got a better understanding of scale now, something I keep trying to do on this channel.
Thanks again for explaining all of this to us !! Much appreciated !!!
Thanks, glad you appreciate this!
Really well presented, thank you
Thanks for saying so.

The transition from Earth craters to Mars craters was *chef's kiss*
Ha, glad you liked it!
I look forward to your frequent Mars updates ! :-)
Really well produced and easy to understand.
I really feel included in the journey of the Mars Rover and its exploration.
I only hope that you would get way more subscribers !!!!
As you earn that and I hope your videos dont stop
Thank you so much.
Thanks for the really encouraging feedback!
You make rocks look interesting. Much appreciated.
Great, glad you think so!
I have to say, your videos are exceptional! I thank you for them.
Thanks for saying so!
1:00 beautiful transition.
Thanks!
Super interesting! Well done, Mars Guy.
Agreed. Thanks Mars Guy.
Glad you liked it.
A location with a messy story, but Science can untangle it. Thanks.
Trying to make sense of it!
@@MarsGuy Note that at 01:56 the process can involve older strata contained in the ejrcta ending up overlaying younger strata surrounding the impact. That is what I was thinking of when I made that comment.
It was , as always, really interesting, and amazing to see how the impact zone reacts almost like a droplet hitting a liquid.
Good morning MG it’s great to be on the other side ,also that is a great example of how an impact crater is formed great work as always see you next week Rick NYC
Thanks, glad you appreciated this episode.
Mars sounds like a great place to be, soo peaceful 😊
Like death.
Happy New Year and thanks for the endless stream of updates from Mars, this is so interesting.
Thanks, and to you too.
Thank you, Mars Guy. Your channel is the best.
Thanks as always.
We need to figure out what to do to get you on the algothrim, your channel deserves so much more veiws/subscribers, keep up the great work.
Thanks, happy to have such appreciative viewers.
Awesome narration!
Thanks!
@MarsGuy Your smart plus you must be "Ladies Man"! Space is the place! Dean( Soul) Toronto
One day you'll be the first to report finding actual Illudium Q-36 deposits.
Thanks for the BEST channel!!!
Ha, I'll share whatever news comes from the mission!

Yes, nice to have discerning and thoughtful viewers. Thanks for being one of them.
A thoroughly absorbing episode. Many thanks Mars Guy.
Glad you were absorbed!
Mars Guy: "Nature's most destructive process".
Siberian traps: "Am a joke to you?"

Ha, happy there's a regular reminder for you!
Again an awesome video. This really is what Science communications should be like!
Thanks, glad you think so!
Thank goodness for an atmosphere and an iron core.. keeps a lot of nasties out! We sometimes forget the fragility of our pale blue dot. Well done MG!
Thanks!
Sunday school on all things Mars, check in folks! Cheers 👍💪✌
Thanks for being a good student!
@@MarsGuy Well, I don't know about good on an exam, but motivated and interested for sure!
So happy Mars Guy made it to 2025! Just love this first video of the new year. The picture of the impact with "melted" rock pouring over the rim is indeed cataclysmic! Looking forward to my new year filled with Mars Guy videos :)
Still going in 2025! Glad you're still watching.
*Wow, in our lifetimes we have seen MARS close up!*
Another fascinating explanation 😮
Thanks again.
Since it's clear that running water was there after Jezero was formed, will Perseverance be able to show if running water was present at the time of the impact or did that come much later? Thanks again.
It's really the orbital images that best tell the story of the flowing water. The channels must have formed after Jezero crater formed.
It's rock-hard to wrap my thinking around the suggestion we're looking at terrain created as-is Four Billion years ago -- generally unchanged since. As most of our geological examination is done on tbe Ever-Changing Earth-Surface. Four Billion Years ago Earth looked hella-different. ☆☆😊

Glad you appreciate and recognize the effort. Fortunately, I've been able to "recycle" green screen video recorded for the first episode. Still takes some editing though.
1:26 Looks much like the piles of ejecta that can be found around Barringer Crater in Arizona. Very cool.
Good observation.
One of the only good things about the future is how we all casually look at pics from the surface of Mars like its no big deal. Like " More rocks! Neat!! "
Glad you appreciate the wonder of it.
Cheers from the Pacific West Coast of Canada.
Thanks from AZ!
You make me feel as if I'd actually been there, and even understood geology!
Great, glad to know your reaction!
:49 As you're zooming in on the Manicouagan impact crater you pass right by a much huger partial crater outline at the southern end of Chesapeake bay.
So it's not Slim Whitman's "Indian Love Call." that killed off the Martians?
nothing much to add so here's my food for the algorithm, may your channel expand.
Thanks
The rover's SuperCam has captured detailed images of the rocky outcrop, revealing textures similar to impact heights found on Earth. This texture provides clues about Mars' geological past.
Always a terrific presentation! I'm starting to wonder whether it will be easier to bring the samples back to a laboratory, or bring a laboratory to the samples.
Thanks. One of the motivations for returning samples is that so many instruments and techniques used in labs on Earth could never be sent to Mars.
@@MarsGuy Thank you! I admit to being slightly facetious there. It's just that we've got so many samples now scattered all over the place, that the effort required to gather them all up and bring them back, is looking increasingly Herculean, (and expensive). I hope we can.
Very much appreciate your no-nonsense straight up , er, updates! NASA's public outreach could learn a thing or two...
As kids, my brother and I had to attend Saturday cataclysm classes for one summer after we were switched from Catholic to Public school. 😁 (sorry)
Ha, good one!
If only there was a Mars Sample Return Mission😢
Is it canceled ?! Or are you presuming that trumptydumpty will cancel ?!
One is planned. Isn't it?
Yes, ESA is building a rover to pick up Percy's sample tubes.
@davidwuhrer6704 The rover is cancelled, but in current plan ESA will make an orbiter to catch the sample in orbit and deliver it to Earth.
Current plan for retrieving samples seems to be using Persaverence and maybe one or two helicopters(but there seems to be a landing mass issue).
your second earth zoom to a crater displayed a nice round blue circle on the left side too.. a bit bigger in fact..
Yes there are two "Clearwater" craters (West and East) next to each other.
It'd be really cool if we could match a crater to Martian meteorites found on Earth by chemical and radioisotope analysis.
That 100m distant outcrop almost looks like an H.R Giger sculpture.
Great episode 🤩👍
Interesting comparison (had to look it up).
Thank you
And thank you for your excellent work. Makes mine look better!
I'd love an hour long episode. Dont post for 3 months, then give us all a mini Mars movie. Just long enough for a long bath.....
Ha, well, that would be a long bath!
*Thanks Mars Guy! U Da BEZT!!*
Ha, THANX!
Think it would be interesting to have a rover there that can dig down and the deeper the better. Would want to see what its like under the sand in some spots.
Mars Guy, are they your Swiss Army knives? (I think I've noticed more than one kind). You have a collection?
The one in this episode is not mine. That image comes from the cited paper. But typically I do show mine (just one).
@MarsGuy :-)
Thank You Mars Guy! Sadly the rock seems to be too fractured to create a nice core.
Maybe so. In any case, Perseverance has moved on now without coring.
2:09 It's funny how this resembles an object falling into a body of water.
Question: What is the age distribution of the MAJOR meteorite impacts on Mars? What is the youngest major meteorite impact on Mars? (For Major, let's say one that left a crater of a 100 meters or more.)
I reported on a newly formed 100+ meter crater in this episode: ua-cam.com/video/VMv57oPFSi8/v-deo.htmlsi=D6wS-txkBXzJVxVe

Thank you. I am curious about what changes are occurring in a newly formed crater of that size.
Fine stuff. One minor observation: I have no idea what size that coin is. May I suggest a CR2023 battery, your trusty Swiss Army Knife, or - heaven forfend - some kind of ruler?
The coin is shown with an annotation indicating 24 mm.
@MarsGuy Ah, sorry, missed that on the small screen.
I do not predict these samples will be returned to Earth any earlier than 12>15 years from now.
👍
Thanks mars guy
You're welcome
Great
By cataclysm I thought flood. Meteor strikes are kind of mundane on Mars.
Occupy jezero!
Sad that we now think in terms of "If returned to Earth". There may be hopeful news on that front in the coming days with the launch of Blue Origin's New Glenn rocket. Many hope that it will significantly reduce the cost of getting large payloads to Mars. Launching, of course, is only a portion of the cost, but it's a hopeful sign.
As I have said before, these videos would be great for schools....Mars Guy needs a logo patch on his suit or helmet...
Thanks again for saying so.
Shock waves don't behave the same on Mars as they do on Earth...There is a reason why???
I don't think using green can be accurate for mars.
We can't know what type of plant-like cells dominated if at all.
I don't think it's implausible. Red wavelength to provide heat, blue energy. Thus reflects green.
👍😎
Has ai already been transmitted to mars?
I hope nobody got hurt.
How do you think all the Martians died?
This planet is dead since then. No continental drift, no magnetic field, no significant erosion, altough it has atmosphere and winds. It would be a miracle if we find life there today. But that´s not the point...
👍🤘❤️🔴
" Scientific goldmine. If returned to Earth." Might it not become easier ( and cheaper) to send a robot laboratory to Mars ?
No, this has been considered for years. There's just no way replicate the capabilities of labs on Earth with robotic labs on Mars.
@@MarsGuy Thanks... my experience of analysis is half a century behind the times. I should have checked with my NMR daughter before posting to you.🤗
☕️🇺🇲
Anyone else getting this is a foreign language? Great video as usual but keep defaulting to French??
Hm, that is very strange, and out of my control.
Nope.
A great way to begin a new chapter, with MarsGuy on the outside of a crater, looking back through time. What a timely update on the prospects of shipping a sample of impactive to Earth for analysis.
btw: Hearing rummers of an update from NASA on its Mars Sample and Return mission this coming week.
Glad you enjoyed the new chapter. And yes, there was an update on MSR today, but it was thin on details and didn't provide much certainty.
👍
