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.

@@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.
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.

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.
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.
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!
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.
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.
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.
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.
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.
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.
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.
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!
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 :)
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?
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.
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.
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.
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)
Fascinating. Who names these locations? How is the name of a location decided? Can other countries call these locations something else?...I don't know what if they called Jezero Crater "The Big Chasinky" instead? Would we have to abide by that?

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.
@@halcon2134 - I know you have to heat it to bend it into a complex shape, and just hot enough comes just before brittle. What are we talking about btw?
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!

Boring, the next one that has robotic arms with hands and clamps to hold tools and rocks, to make houses, and small piles of stones.
This one has a laser that vaporizes rock.

O😅h my godness, seriously, with a matching spectrometer or just for fun.
@@halcon2134 - It has a spectrometer. It was originally called the Mars Science Laboratory.
@@GWNorth-db8vn
Oh thank you, I don't know if you already know that aluminum with thermal stress fractures quickly or not yet?🥰
@@halcon2134 - I know you have to heat it to bend it into a complex shape, and just hot enough comes just before brittle. What are we talking about btw?
Excellent piece! Thanks!
I confess
It was me.
Great vid. I suggest a de-esser for the audio.
Thanks
It isn't centered and it doesn't look quite straight vertically.
Out on Broken Ankle Plain, how did the Rover get through that, even walking it would be hazardous.
What is the function of that post? Why is it even there?
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!
Curiosity is named after the "F around and find out" rule. It gets pretty bored out there.
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 ?
What sort of suit is that? Looks so cool every time!
Thanks, glad you like my DIY effort based on motorcycle gear!
@MarsGuy Oh wow neat! It looks remarkably close altogether to the spaceX suits.
That old robot doing good, if he gits a little crazy-stream, what the hey? Still writing its name in the snow....
Are we sure it is a hole and not a pile left in the middle?
Like moon craters when you turn the picture upside down.
How much longer can this rover last?🙂🙂
The mission was scheduled for 90 days.
Well then NASA is certainly getting their money's worth from this project.
@@glencrandall8334 - I have plenty of stories about the building of this thing. My fingerprints are all over it. At one point, they binned the whole aeroshell assembly and re-designed it from the ground up. 200 million right there.
*I think it would just be a lot easier if Mars Guy was on Mars. Think of all the great videos !!!*
He's NOT?!
Make the scientists curious about Curiosity. What better way to divert some attention from the "newcomer" rover?
thankyou mars guy
still going strong like our rover..
You're welcome. More to come.
If it the simple earthly definition of liquified H20, than fine. But since it’s mars…define water. Mars water.
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?
That mars guy seems too short
Why a center post at all?
Sad.
Looking over scraps pushed to all of us by liars, most likely pictures of somewhere here (Devon Island) that have been given a color treatment.
Calling it now - the popular answer to 'what went wrong', will, from people with less scientific rigor, be 'aliens'.
This is my hole! It was made for me!
I don't believe Olympus mons is a volcanoe looks like a weld pile to me
No that's the glorious hole. 🐨👍
My guess is it was a defective rock!
Hmmmm looking forward to learning what happened
Why haven't they sent the rover to the face of mars what are they hidding
