When this news broke my first thought was "I can't wait for what Mar Guy will make of this!" And lo and behold, a fire and brimstone special episode! Thank you so much for this!
So glad to know that this is your go-to channel for Mars news! Glad I could deliver for you. And thanks much for showing your support and appreciation for this channel. Much appreciated.
I like the images from both rovers, which are both of overwhelming quality. The longvity of these rovers is astonishing, Curiosity already for 12 years and Perseverance for more than 3 years. I hope Perseverance will also be active for more than one decade.
Curiosity has been there for 12 years? God time flies. I didn’t realize there was such a big gap between the two though, now I’m wondering why they are so similar. I understand perseverance has some different things, but it’s not that much different. It’s not almost a decade worth of technology different.
My assumption is that it formed near a volcanic vent, then travelled to it's current location via an asteroid impact at the volcano where it formed as part of the ejecta blanket.
If these are sedimentary beds, it would be even more interesting, as the pure sulphur in those deposits is thought to be derived from bacterial action on gypsum and anhydrite (both are calcium sulphates). There are deposits of that type in Texas.
Hello Curiosity!!!! It's so good to see you here on this channel! Thank you, Mars Guy, for the update on Curiosity. As much as I love Perseverance, all our rovers need their time in the limelight. We mustn't forget any of them. All the hard work and information the rovers and their teams bring to us is invaluable. Mars Guy, you're the best!!
I've seen NASA report on the same thing, namely the discovery of pure sulfur on Mars by Curiosity. Well, to be frank, your report is much more informative, concise with better narration. I wish it would be longer. Thanks!
@@twonumber22 I know - and I'm very grateful they put virtually everything online - I've been so giddy with the Bennu papers... But if one has a daytime job one does not always have the time to listen to hours long lectures or read papers. MarGuy is a bona fide geologist, doing a TLDR without dumbing things down too much. Or making it too 'entertaining'
It is so exciting to see light and whitish rocks amidst so many dark and reddish ones. As soon as I saw the image elsewhere, I pined for it to be Sunday and Mars Guy's elucidation. Thank you.
Thank you. I have been looking at the raw images of MAHLI instrument and couldn't wrap my head around what I was seeing. Pure as a tear sulfur crystal. How is that possible? The hues and layers inside the fragments, pure joy for the eye. I need more of this. Let the Curiousity have the better of it and smack the next porous rock, in slow motion). I want to savour every millisecond). I want some UV light at night again, please). I know it's impossible but i also want the sun to illuminate it from behind, so that the sun rays would shine through. Thank you for the episode!
Brimstone areas on earth are smelling terribly like sulfur dioxide. Would this sulfur on mars smell at all without the presence of oxide? What a great video again. For me exactly the right balance between information and entertainment. Keep on going like this. You don't need millions of klicks, you are doing the best for us 36K subscribers with your high quality information! Thanx for all of that!
Thanks @drguenther for being among the selective viewers! And it's actually H2S, hydrogen sulfide that has the rotten egg smell, which forms from volcanic emissions even without oxygen in the atmosphere.
This may be outside of your expertise but as you mentioned the low oxygen on Mars I thought I'd ask! Before the Oxidisation of the Earth's atmosphere how did lack of oxygen affect Volcanic Lava flows? I presume fire wasn't possible so did Lava react to the atmosphere the same way as it does to sea water in forming hard crust pillows or did the lack of oxygen have no effect and it flowed the same?
It may not bubble itself, but from liberating gas from the surface it flows over. You can see it by tossing molten aluminum on seeming dry concrete or lead on wood.
2:45 Those sulfur crystals sure look amazing. Also, Curiosity must weigh a lot to be able to crush that rock so nicely, but maybe the strength of the rock wasn't strong either, not bonded well. Thanks for my Sunday fix on all things Mars! 👍💪✌
6 wheels to spread the load too if memory serves so notionally 60kg per wheel. That said the wheels are metal so the point loading as they roll over is presumably immense.
04:19 Awesome imaging. I am in my armchair, yet a big budget, plus an excellence of engineering, plus an intellect in imaging (sorry, getting poetic here) have enabled me to see sulphur on Mars in such detail. I am from New Zealand and appreciate the formations I have seen many times getting a mention.
Sulfur is a versatile element that could be used in various ways by humans on Mars. Here are some potential applications: 1. Food production: Sulfur is an essential nutrient for plants, and Mars' soil lacks it. Adding sulfur to the Martian soil could help support plant growth, making it possible to grow food for human consumption. 2. Energy storage: Sulfur has the ability to store energy in the form of sulfuric acid, which could be used as a battery or fuel cell. This could provide a sustainable source of energy for Martian settlements. 3. Water purification: Sulfur can be used to remove impurities from water, making it safe for human consumption. This could be particularly useful on Mars, where water is scarce and purification is crucial. 4. Medical applications: Sulfur has antibacterial and antifungal properties, making it useful for treating infections and wounds. It could also be used to create medical supplies, such as bandages and dressings. 5. Construction materials: Sulfur can be used to create building materials, such as concrete and mortar, which could be used to construct habitats and infrastructure on Mars. 6. Propulsion: Sulfur can be used as a fuel additive to improve the efficiency of propulsion systems, such as rocket engines. 7. Radiation shielding: Sulfur has been shown to have radiation shielding properties, making it a potential material for protecting humans and equipment from harmful radiation on Mars. 8. Bioregenerative systems: Sulfur can be used to create bioregenerative systems, which could recycle air, water, and waste on Mars, making it possible for humans to live sustainably on the planet. Some potential ways to obtain sulfur on Mars include: 1. Mining: Sulfur deposits could be mined from Martian rocks and soil. 2. Recycling: Sulfur could be recycled from waste materials, such as rocket fuel and other industrial processes. 3. In-situ resource utilization: Sulfur could be extracted from Martian rocks and soil using in-situ resource utilization (ISRU) techniques, which involve processing local resources to create the materials needed for human exploration and settlement. Overall, sulfur is a versatile element that could play a crucial role in supporting human life on Mars.
Thanks for putting together this excellent discussion on the background and importance of the surprising discovery of pure sulfur rocks by Curiosity in a short time. Your last comment about no chance of fire for this brimstone might be a clue to how this sulfur ended up in these rocks. The lack of oxygen in the atmosphere of Mars must affect the chemistry of some rocks at the surface.
@@DUKE_of_RAMBLE his very first or so episode had him doing a complete episode like that, but IIRC it was waaaay too costly to continue in that style. Maybe now with more followers and income, short snippets have become affordable.
It's very nice to see Mars Guy animated now :-) . By the way, the yellow coloring and sulfur vapor can also be seen on the Nea Kameni volcanic island, which lies in the Caldera in front of the famous Greek island of Santorini (Thira) in the Aegean Sea (I visited this in 2006).
I'm NO expert, but that site on Mars looked to me like an impact site, compete with the risen middle portion (Mt Sharp). One only has to look towards the Moon for similar structures. _(at least that's what it immediately reminded me of)_ So could it be that the site had indeed been hit, where a subsurface sulfur deposit had been liquefied, which then flowed over a vent of sublimating CO2 and that's what created the "air pockets" in the cooled sulfur?
Geology field trip I burned my fingers looking for sulfur crystals on small cliff. The low 5 foot face had steam vents that created small crystal complexes. We were at China Lake Naval Weapons Testing center. (With permission). It was a small competition to find a good one. I tapped the face with my hand pick and unexpectedly opened a steam vent right at the handle. Ouch. Bummer. Not a major burn. Just a hurting for a while.
Thank youuuu for your video of the history of this world or some of it 💕 it was really interesting to watch it and see how much it has changed since then ❤️ thank youuuu and thank youuuu
It floats and could have been deposited by ancient water. I am surprised that was not mentioned. There are tons of pure sulfur balls on the shores of the Dead Sea in Israel. It floats.
If it is truly not a volcano and just setamentary rock, You have your answer. Elamental sulfur has a density of 2.07 g/cc. resting a fair distance between 1.873 g/cc Cesium Cs 55 2.07 g/cc Sulfur S 16 2.26 g/cc Carbon C 6 I would stand to reason that it settaled out all into one location after whatever event brought it to the crater from upstream.
Would the lower air density help allow the formation of bubbles? I am sure you would of mentioned that if it was true Anytime new evidence shows greater complexity just makes me excited
Sudbury crater on earth generated sulfide melts, which are still mined for Cu and Ni today. Perhaps this sulfur is a remnant of the gale crater impact event, instead of volcanic activity.
Yeah, that's what I was thinking. Was water flowing on Mars when the Crater formed? That's a big Crater, lots of residual heat would create hot springs. Sulfur Nevada, you can find nice sulfur crystals formed by hot ground water springs long ago.
@@DigDougDig Well in the case of Sudbury, it was literal sulfide melt, not hotsprings. Sulfides are of course no elemental S, so I put no weigh behind this hypothesis. Although it could probably be enough that molten rock that filled the crater after the impact degassed sulphur like a regular basaltic lava flow would. Larger sulphur deposits are also found near volcanic lakes. So deposition in a water filled crater lake can also be an option.
A lucky accident - the rover crushing a rock - leads to the discovery of pure sulfur rocks in a non-volcanic area, where they shouldn't even be. Interesting!
When I was hearing articles talking about green crystals being found on Mars I didn’t even read them because I thought it was bs but dang that’s cool that Curisoity actually found green crystallized sulfur.
A geologist's hammer equivalent tool might be faster, simpler, more robust than perseverance's abrading/core collecting tools. (maybe high-speed mode on one of the cameras to see what fragment came from where).
Rite Mars Dude, Glad you kept your helmet on for this episode! If you hadn't mentioned @ 2:46 that this was sulfur crystals I'd have thought it was a plant! TFS, GB :)
The discovery of free sulfur, in larger quantities, on Mars, is very interesting. Sulfur forms the basis for one of the strongest concrete types "Sulfur concrete" that can easily be used for 3D printing of buildings on Mars.
This is one of the reasons that we need human scientists on that planet, because a lot more is hidden underneath all that orange dust that covers everything.
Was waiting for this video, too. Great new discovery! Still don't understand how MG has only 36K subs? I hope ALL of you watching are subscribed!! Share this dedicated creator, folks!
So you visited the Taupo region of New Zealand. Certainly a very volcanic region and many interesting volcanic related areas to visit. I hope you enjoyed your stay. Kiwi David 🇳🇿
@@MarsGuy Really! You must have liked the unique features of the area then. Said to be the site of the worlds biggest volcanic eruption and recorded by the Chinese. I am sure you might liked to have gone to White Island, in the Bay of Plenty, to study Sulfur. But it's a very dangerous place (currently at alert Level 2) and the last sulfur mining plant in the 1980's was abandoned, after an eruption and all they found in body and alive, was a cat. The cat may have 9 lives, but over 30 people have lost theirs, on that active volcanic island. Best to send in the robots.
Could the sulfur be an artifact of the formation of the crater via impact? I expect that the crater would have been molten at some point during/after impact.
00:39 Layers? You know what also has layers? Hint: those wise words are part of a philosophical exchange between a donkey an a Large (not little) Green Man.
Good Morning, Great educational work you are dong. Sulfur or brimstone is fascinating. The way it is spread out tells a story in itself. They landscape tells the story. But what? Love your channel and the information you share. Keep doing what you are doing. Thank You.
Sulphur can react with CO2 to make SO2 and CO it seems exothermic. CO and sulphur makes SCO which I also presume is exothermic. Not sure if it'd work at 1% atmospheric density mind but the possibility of "fire" and brimstone seems to still remain even if you have to try really quite hard lol

It was harder to oxidize iron in volcanic minerals on early Earth with its low oxygen, but other behavior of lava would've been mostly the same.
This might come in handy if future explorers find themselves confronted by The Gorn.

"rocks made of pure sulphur" so just sulphur then.
Distinct from sulfates or sulfides.
So that’s where Hell is….
1:55 "Robinson Crusoe On Mars (1964)" - vibes anyone?
Martian eggs
Easter eggs 😀
Nice Travolta move 😅
Great to hear from Curiosity Again, Still Knocking Out the Science Data, the old timer Still Swinging the 🪨🔨😉
True!
Thank You Mars Guy! News from other side of the Mars are always welcome!
Great, glad you think so!
Yet another stellar Mars Guy video! Thank you so much!!🎉
Thanks again!
Like the good old Mr. Spock used to say: "Fascinating!"
With a raised eyebrow!
@@MarsGuy 😂
what an incredible zoom in to start the video. mind blowing.
Glad you liked it
Sulphides next 😃
Wow. Great to see❤
Very interesting as always MG, thx j-M ⛏️👍🇬🇧😎

The sulphur could have come from an asteroid impact.
I wonder if these sulfur rocks could be the result of being scattered by a meteorite impact?
That's one of many possibilities.
Fascinating. A good mystery is always entertaining and can sometimes lead to new insights. 👍
True!
With sulphur and perchlorates on Mars, you have the beginnings of a flashpowder industry :)
Fascinating, as usual. And nice to see a wee touch of my home (New Zealand) :)
Glad you enjoyed the wee touch of NZ!
Sulfur might degas or bubble in lower pressure environments
Mars guy takes off helmet and smells rotten eggs
Ha ha! Only if there's hydrogen sulfide (H2S) gas.
Sulphur can react with CO2 to make SO2 and CO it seems exothermic. CO and sulphur makes SCO which I also presume is exothermic.
Not sure if it'd work at 1% atmospheric density mind but the possibility of "fire" and brimstone seems to still remain even if you have to try really quite hard lol
That thin atmosphere is 95% CO2 with negligible O2, so really tough to make fire.
