My car is older than that heroic rover. Every week something starts to groan. That they made the rover capable of enduring this long is beyond amazing.
Seems too big to be from the post, plus there's no degree of distortion to the hole like you'd expect if the brush makes an oblong clean spot. It also seems scored awfully precisely with specific tool marks so it happened when the brush was not moving laterally. I'm going to bet it snagged a small rock against one of those screw heads around the center post and briefly turned into a drill before tossing it. Maybe. There's really nothing else on the tool to leave that type of mark that I see.
@gerryjamesedwards1227 yeah, I really can't come up with a good reason for it's displacement. It's in the wrong direction of how the brush moves to be right. If one of those brushes takes off flying next time the tool is used, i might not be too surprised. Maybe that's a part of the mount spinning as it breaks loose, but looking at the diagrams of the brush mounts I don't really see a way for it to break and spin around on its own axis while the rest of the head spins. Also I bet there's some sort of vibration sensor that would give warning of that type of failure away before it flings parts all over.
That is a strange hole in the rock. It seems to have a set of terraces on the sides of the hole, which doesn’t match the simple shape of the post. I wonder if some very soft material was eroded out by the brush rotation.
I don't think those are terraces. I'm pretty sure those are just the layers in the sedementary rock. Drill a hole into anything with layers and it will look similar to that.

I can only guess that dust and grit has got behind the spring loaded center post and stopped it from compressing inwards. The downward pressure has made it force into the rock. So the rock might be fairly soft in this particular case. I guess they will use the camera to observe the next brush clearing procedure to troubleshoot the problem.
I think one of the gas giants has two. Guess that would be a bi-curious hole? I heard it was Uranus. (Seriously, nobody puts CURIOUS HOLE on a RUclips thumbnail without expecting this. 😂)
Thinking that the rover is a stable point is wrong imho. It could have slowly tilt while brushing the rock. putting more force on the instrument. Just a guess.
If only one of it's wheels slipped off one of those rocks, yeah I could totally see that. It may be 2000 lbs, but all it takes is a little shift in weight to move the entire arm an inch or two.
@@AySz88 I genuinely don't know what you're trying to say. All I'm saying is that NASA knows if the rover is stable or not. Sonnell had a decent theory about why the hole may have appeared but NASA wouldn't start brushing before knowing the rover was stable. If the issue was stability, NASA would already know and they would have mentioned it when they gave us all the other information.
@@lllMithrandirlll The last sentence is what I was trying to address - IIRC raw images and some drive data are automatically released from JPL, so we do often end up seeing news and images in e.g. Mars Guy updates even before JPL releases an explanation to the press.
A good point mate! 🤝 I wish more of my machinists were as observant as yourself! You in the U.K. ? Fancy working on experimental aircraft by any chance? 😅🤝
Maybe when the tool was retracted from the rock it jerked sideways(to the 11 o'clock position in the photograph). This made new brush marks that obscured the old ones.
Always fun to get news from the other rover crawling around on our reddish neighbor! BTW: At the moment it can be beautifully seen in the morning until maybe 7.00, quite high exactly in the west, even when in the east there is already some dusk rising. And Jupiter is sitting lower to the right in all it’s beauty!
@@schrodinger3467 those aren't synonyms. synonyms have the same meaning. "Impossible" and "improbable" don't have the same meaning. The former means it literally can't happen while the latter just means it's unlikely to happen.
I highly doubt testing the same rocks will happen before humans arrive. Only 6 rovers are on mars and 3 of them don't work anymore. Plus the space agencies aren't going to send multiple rovers to the same area. For example Curiosity is nearly 4000km away from Perseverance.
The most striking feature of this anomaly is that the 'hole' (if indeed that's what it is) is not concentric with the brush marks; It's off centre. Although it looks as though the brushes have moved along an axis to clear a larger area, the hole is also not inline with axis of travel. If there were debris caught under the brushes, this would still result in a hole concentric with the brush rotational axis.
Mars' low gravity, & lack of rain leaves huge, fragile soil clumps, easily abraded, but look like boulders. It may just be dried mud. Soft as dirt clods.
Curiosity is the best. Well also landing in Gale crater below MT sharp great choice! Imagine all this in blue and green, Mars was just like Earth for over a billion years and this was prime sunbathing.
Perhaps I misunderstood. The central post probably is there to prevent the whole apparatus from getting into contact with the rocks. That is my guess. I suppose the wires will wear eventually and with use will become less stiff too. The post will prevent damage in the future
I would love to see the force vs time data from the arm during the brushing process, if at any point there was a sharp spike then I would expect that to hike to be caused by the rigid post.
Mars surface to me looks like devastation from how I imagine the result of a nuclear war to look. A lot of the rock looks to have been shattered by some cataclysmic event and many of the flat rocks laying on the surface appear to have been melted at their edges. but hey what do I know?
No doubt they will send the little children who are at this minute digigng the mines in AFRICA for your electric car battery. Why send robots which cost a lot when they can abduct kids who will do it for nothing. l would put a vomiting emoji there but can't find it...
Unbelievable how much of the internals are exposed to atmospheric dust. How about getting some form-fitting covers to smooth out exterior and create a dust free interior .
Mass is a massive consideraton. Adding form fitting covers would add way too much mass to the rover. For every extra kilo of useable payload sent to mars, you need hundreds of more kilos of fuel at liftoff because not only do you need to lift the extra kilo of payload but you also need to lift the extra fuel. The Atlas V rocket, which sent the perseverance rover (weighs about 1 metric ton) to mars, contains about 285 metric tons of fuel.
Bulls Eye craters are actually not that uncommon but are usually a lot bigger. With it from modern charged thinking perspective, being created by an electrical discharge.
one thing that I don't understand with the naza, they are able to show us clear images of Mars, but they are not able to show us such precise images of their so-called boots under ground on the moon, someone can show me equally precise images of appolo 11 on the moon
Indeed, l would like to see proper images of that also! l bet they didn't go there at all, and why aren't they showing us images TODAY of the moon if it was so easy to go then?
What went wrong? What went right?. The central post made enough of an indentation to indicate that rock is pillow-soft. Stainless steel isn't all that hard, and the stuff on DRT isn't meant for surface abrasion, but a heavy-duty floor broom. That rock deserves a ride home.
You a need a fifties flashy banner yelling "Mystery On Mars!", accompanied by a dozen of trumpets, before showing the actual pictures and telling the story!
Looks like the brush bristles got bound and twisted in the hole next to the post.. @3:04 and @3:12 you can see a bit of a dreadlock twist still in the bristles. They got too close somehow.
there is a clump of bound together wires in the photos. this might have caught on the surface during spinning, staying in one location while pressed down, acting as a drill.
Entirely willing to be wrong here, but to me it looks like there are a number of bristles on one brush that seem twisted together. My speculation would be that a discontinuity on the rock permitted some bristles to bunch together, effectively becoming a drill. If this is the case, the question becomes whether this has damaged the brush in a more permanent way, or if the bunch will untangle over the next one or more uses.
It's good to see updates on Curiosity once in a while. With Perseverance and so many other missions stealing the spotlight in recent years it's easy to forget Curiosity is still trucking along and doing science half way across the planet from its younger sibling rover. Also maybe it was an optical illusion but the shadows on that divot made it look convex rather than concave.
If he post stuck out and drilled the hole - then it would suggest the spring or whatever is used to retract it - has jammed. Cause ? possibly some wire from one of the brushes may have weakened - broken off and found itself inside the mechanism.
Why are you ignoring the twisted wires on the brush? If a small imperfection in the rock grabbed 10 or so bristles of the brush, it could potentially hold them in place while they're spinning, drilling the hole.
Are there similarly soft rock samples for testing here, where you can try to reproduce it and possibly get a feel for how soft the Martian rock is? Are we talking talc levels of softness or what? How do you quantify that?
Interesting question. I remember all the trouble ExoMars had trying to drill a 2 m deep hole. Now Curiosity accidentally drills a hole. (smaller, but ..) Shows the variation in Mars rock hardness, and how much about Mars rock composition we have yet to learn. These unexpected discoveries are most intriguing. Note: Curiosity drilled its first hole on Mars in February 8, 2013. (Earth year reference, Sol 182)
Look at the image at :20, The wires in the two brushes tangled and stiffened. Nothing impressive to see here other than mans tools on a distant planet. That in itself is incredible.
Hi Mars Guy -- love your channel! Holes like this are actually common in soft rock and thought to be caused by the tangled section of the brush rather than center post contact. See e.g. sols 905, 1057, 1934, 2055, 2168, 2826, 2470, and 3203 (list ends there because that's when I first investigated these!). This one does look a little cleaner than the others and more symmetrical.
Rite Dr Mars Dude, Played the rock hole clip over n over but all I saw was a stalagmite!🤔 I think n eyes are broken 🤓 Stay safe n well Steve. TFS, GB :)
I don't know how the height of the brushes is ascertained. Is it totally automatic? Does NASA manually change the height of the brushes as the brushes are subject to wear and tear? Or are these adjustments done automatically as well? I assume that after 400 brushings against rough martian rock there would surely have been some wear on the brushes. Even if they just get bendier. How does Curiosity mesure wear and tear on the brushes? Even the toughest metals are subject to abrasive wear and tear. Either that or there were some freaky shallow bumps and angles or holes or cracks in the rock which bamboozled Curiosity's sensors.
What? No one recognized that as a symbol of Chakotay's ancestors, the SKY PEOPLE, who visited Mars first and then visited Earth later as mankind developed on our planet.
A question about cracked rocks. Just what is the process that causes the rocks to crack? Is it just temp change or is there water involved? Or even CO2 freezing in the cracks?
Likely multiple processes, like thermal cycling, maybe freeze/thaw of water, some tectonic movements, but probably not CO2 freezing because this equatorial location doesn't get cold enough.
We're so fortunate to have such planets within travel distance. Imagine if the closest planet was 100x farther away than Mars, or if everything in the solar system was completely inhospitable. We're fortunate to have a tame and stable sun that barely varies in intensity over long periods of time. Fortunate to have wireless communication via electromagnetics. Things we do are hard, but at least they are possible. And good thing that light travels everywhere in transparent space. Imagine if space had density and all you saw was fog. Imagine if our own atmosphere was foggy and no light reached surface, like in deep ocean, and what if we had not evolved eyes because of it, or if there was no sound, and we didn't grow ears. So many things could've been different, and isolated us from the rest of the world. Instead, it's all open in plain view. From our home, to the edge of the universe at the beginning of time. Like an open map. And we can send rovers to Mars! How cool is that!
you probably did a post on the odd Sulphur rocks curiously discovered, but maybe I somehow missed it. Just saw some photos of the formations and they look otherworldly, but it seems they were discovered in July. Did you feature it on an episode? Amazing segment, as always!
I got my hopes up there for a minute, wondering if those squirrely lines would be some kind of rock worm creature. I'm not disappointed though! 12 years on Mars and still going is awesome.

Looks like very soft material. Clay like.
Thanks for the updates.
I'm a Irish fella & dig a hole. I can,t break in too little oxygen 0.5%.
Mars a day helps you work, rest & play. Thank you Elon Musk.
Looks more like a raised widget than a hole to me, but I accept that this could be an illusion.
Good stuff, Mars Guy. Great illustrations and explanations.
Thanks, but this may still be the wrong explanation.
Maybe we should dig deeper. I'm still looking for Jimmy Hoffa.
😂🤝 I read that in Papas’s voice from Point Break! 😅
Great videos. Your culprit is not the post, but the small group of twisted stands on one brush in the photos.
Yeah, that is a possibility.
It looks like the brushes are getting worn and the hub of the tool is now penetrating the ground.Call service.
Rite Dr Mars Dude, Played the rock hole clip over n over but all I saw was a stalagmite!🤔 I think n eyes are broken 🤓 Stay safe n well Steve. TFS, GB :)
Ha, try turning your head or screen upside down!
It's definitely the post. That would make the most logical sense. Thank you for not jumping to "aliens" :)
I don't know how the height of the brushes is ascertained. Is it totally automatic? Does NASA manually change the height of the brushes as the brushes are subject to wear and tear? Or are these adjustments done automatically as well?
I assume that after 400 brushings against rough martian rock there would surely have been some wear on the brushes. Even if they just get bendier. How does Curiosity mesure wear and tear on the brushes?
Even the toughest metals are subject to abrasive wear and tear.
Either that or there were some freaky shallow bumps and angles or holes or cracks in the rock which bamboozled Curiosity's sensors.
Excellent piece! Thanks!
Curiosity is named after the "F around and find out" rule. It gets pretty bored out there.
What? No one recognized that as a symbol of Chakotay's ancestors, the SKY PEOPLE, who visited Mars first and then visited Earth later as mankind developed on our planet.
It is not a hole. It is a small peak standing up. Probably dust, sticking together due to static.
A question about cracked rocks. Just what is the process that causes the rocks to crack? Is it just temp change or is there water involved? Or even CO2 freezing in the cracks?
Likely multiple processes, like thermal cycling, maybe freeze/thaw of water, some tectonic movements, but probably not CO2 freezing because this equatorial location doesn't get cold enough.
That old robot doing good, if he gits a little crazy-stream, what the hey? Still writing its name in the snow....
Thanks for sharing. Do you think they pushed the brush a bit too much into the rock?
Thanks for watching. It's possible this hole is the result of tangled bristles, as other commenters have noted.
I confess
It was me.
Out on Broken Ankle Plain, how did the Rover get through that, even walking it would be hazardous.
If it the simple earthly definition of liquified H20, than fine. But since it’s mars…define water. Mars water.
thankyou mars guy
still going strong like our rover..
You're welcome. More to come.
We're so fortunate to have such planets within travel distance. Imagine if the closest planet was 100x farther away than Mars, or if everything in the solar system was completely inhospitable. We're fortunate to have a tame and stable sun that barely varies in intensity over long periods of time. Fortunate to have wireless communication via electromagnetics. Things we do are hard, but at least they are possible. And good thing that light travels everywhere in transparent space. Imagine if space had density and all you saw was fog. Imagine if our own atmosphere was foggy and no light reached surface, like in deep ocean, and what if we had not evolved eyes because of it, or if there was no sound, and we didn't grow ears. So many things could've been different, and isolated us from the rest of the world. Instead, it's all open in plain view. From our home, to the edge of the universe at the beginning of time. Like an open map. And we can send rovers to Mars! How cool is that!
Great perspective!
you probably did a post on the odd Sulphur rocks curiously discovered, but maybe I somehow missed it. Just saw some photos of the formations and they look otherworldly, but it seems they were discovered in July. Did you feature it on an episode? Amazing segment, as always!
Thanks. And yes, I did two episodes on the sulfur rocks: #172 and #174.
@@MarsGuy thank you!
NASA - Let's pick the most boring place to explore so we don't stumble on any artifacts!
Why would there be artifacts?
@@GalacticNovaOverlord So you'd pick a spot even more boring?
It isn't centered and it doesn't look quite straight vertically.
the Mars guy started showing hole
I could be wrong looks like deep in hole same color as surface leading to was it a rock maybe at centre but outer is coatings ?
Great vid. I suggest a de-esser for the audio.
Thanks
Does the rover autonomously decide how close the brush should be with the rock sample? Or is that controlled here from Earth?
Make the scientists curious about Curiosity. What better way to divert some attention from the "newcomer" rover?
Great update, thanks Mars Guy for all you bring to us.
👍💪✌
Thanks for watching.
Why a center post at all?
What is the function of that post? Why is it even there?
Operator error.
I got my hopes up there for a minute, wondering if those squirrely lines would be some kind of rock worm creature. I'm not disappointed though! 12 years on Mars and still going is awesome.
I thought worm hole too. 🪱
