Mars Curiosity rover’s wheel damage is getting worse since the rover landed on Mars in August 2012. In 2017, NASA said the damage is occurring more rapidly than expected.
The wear and tear of the wheels are caused by the hard, embedded rock on Mars when the 1-ton robot drives on them.
The damage isn't identical from wheel to wheel. Much of the damage is occurring in the middle wheels, especially the rovers’ left middle wheel
So far the damage has not imperiled the rover's mission.
NASA has made the wheels of the Perseverance rover much stronger than these to avoid the rapid wearing problem

Perserverance: Don't worry Buddy, you can rest soon, I'm here.
Since the Curiosity Rover has now spent over 8 and a half years on Mars, even if the Rover stopped moving today because of wheel damage, the great success of this mission will not be affected in any way. The lifetime warranty for the Rover was 1 Martian year, or just under 2 Earth years, So it has already exceeded the lifetime required for mission success by over 4 times.
The funny thing is that Curiosity was actually a two-year mission. But it's been holding out for over 10 years!
It landed in 2012, what year do you think it is? 🤣
sorry my mistake 😂
Curiosity was planned for 2y and will run for 15. Dont worry, we charged tax payers for 30.
@@WM_official you don't like paying tax for NASA missions?
As much as I hate to say this, but they built it well. No engineered obsolescence or sketchy software there.
Many people on these comments suggest rubber tyres should have been used. It was never a possibility because at the lowest temperatures on Mars, rubber becomes very hard & brittle, much like glass and would simply chip & splinter away in a very short time. Apart from that it would have been too heavy.
When it gets to the point that it cant move anymore. Hopefully they will park Curiositu in a good spot that it will like a good lander and the instruments will still work for study in that location.
Each wheel on Curiosity is about 20 inches (50 centimeters) in diameter and 16 inches (40 cm) wide. They were milled from blocks of solid aluminum, but are superthin; the nontreaded area is about half the thickness of an American dime. Each wheel also has 19 zigzag-shaped treads (the grousers) that bear most of the rover's weight and provide traction for drives. These treads extend about 0.25 inches (0.64 cm) from the skin of each wheel, NASA officials said.
I wonder how much each wheel cost NASA
Too thin.
Oh.. and the square "slots" on the wheel that are on a small radius of each wheel represents morse code for "JPL"....
They are actually forged rings.
A lot of the folks commenting seem to be confused about what rover we're talking about here! This is Curiosity not Perserverance!
That guy Kevin Martin seems to be confused about how to spell Perseverance!
This has to happen on Mars, the rover is well exceeding in its life on Mars.
So many experts on tyres here.....wow!🙃 Keep Rollin Rollin Rollin Rollin..
yep, so many "experts" in the comments talking about silly ideas like rubber without knowing it's -80° C on Mars and rubber brittles like chips at the temperatures. Cringing.
One of the most important parts. Hopefully the metal stays intact
@@Bakus74 it’s gotta be lightweight, and it’s been on Mars for like 9 years now, it’s doing pretty well as they only intending it for a 2 year mission
@@Bakus74 it’s A96061 aluminum and it wasn’t cross forged.
Entropy comes for us all, eventually.
Curiosity: "I go after I will seek perseverance , only he can help me.
Well, it looks like, a slow beginning towards the end, for my favorite Rover, but hey we're still rolling and that's what counts, for now.
Box Box! Next lap in for the pitstop!
one legend said "That's one small step for man, one giant leap for mankind"
Imagine posting that same line to get likes at each and every Mars video coming out
Just pull into a Sears Auto Center but, it may be hard to find one!
Call AAA.
There are no Sears auto centers on Earth
Surprisingly there still is!
Thanks for your sacrifice "Wall-E" Curiosity
I think they look pretty much the way a thin, solid aluminum wheel, mounted to a heavy vehicle and driving on rocks for years, is supposed to look like. Like having a "beat up old beer can that's been laying in a ditch beside the road" kind of vibe to it. I'd say run it 'til they fall off though! Who knows? Maybe it'll keep rolling on the bearings or something! lol
Stupid to have that much weight on aluminum wheels.
Fun Fact. The square holes spell out JPL in morse code.
All good things finally come to an end and so it is with Curiosity.
Why didn't they use titanium? Light and very strong
NASA did experiments with wire mesh tyres many years ago. Designed to be lightweight and react like real tyres.
where it landed was deep-bottom of ancient lake and plenty of rocks in various sizes are based there. Perseverance should go the planned spots and do drilling as fast as its possible..
Surely there is a better material than aluminum? It is quite brittle. Titanium is far more durable and almost as light. But Curiosity has lasted far longer than its original mission statement so much respect to the design team.
It was just the wrong type of aluminum. There are grades of aluminum that are much stronger.
En que desierto esta ahora, en Australia???, ese lugar es muy frecuentado por la NASA.
Please preserve curiosity. The legend of all time. Perseverance should take care of it from now.
I've seen high speed pursuits in LA run on less for miles.
I think the middle wheels wear more because the front wheels excavate or turn rocks exposing their sharp edges which then cuts through the middle wheels. Bear in mind that rocks on mars are rich in iron and are 'heat treated' by extreme temperatures making them very brittle but very hard like Silex!
I just hope they have made contingencies for this and the parts the tread is attached to can do the same job when the tread is gone.
Would titanium be a better choice ?
It would be very sad if the rover comes to stop moving not because of its end of power generation rather because of wheel damage. Although curiosity has survived way longer than its planned mission but the RTG power supply could power the rover upto like 2025.
It could park somewhere it can operate and prolong it's life by staying there instead of moving around on those weels after they've worn out.
Showing wear, but still a ways to go before I would call them worn out. ☕🐸
SN11 vs Blue origin NS15 Side by side comparison video on my channel !! watch it guys
I got sad after watching it.... feels like someone go there and fix these wheels..... curiosity did a lot a lot for us .... and still working....
Hell send a tire repair truck , it's in nova scotia taking pics 🤯🙄🤣
You had one job!!!
Ti, titanium is much much tougher than aluminum. Designer's probably never thought it would last this long.
They did. Previous rovers have lasted even longer. They just set the expected duration short enough to lower possibility for failure. Tire damage was done in early phase when rocks were too sharp.
When ( what year ) that happened ?
Bridgestone tyre fitter first man on Mars 👨🚀👍🏴
It is amazing that any material can hold up over time in the Martian environment with temperature swings that the device encounters.
Срочно нужен механик на марсе.
BF Goodrich all terrain T/A would work great there!
does it auto destruct when Khan stabbeth it with the geneses device?
It's not dieing... it's adapting. Like a butterfly it sheds its coat and becomes a beautiful butterfly!!!
Its gonna be sad to see it go when it does
What have they done to Perseverance, to combat the problems that Curiosity has with its wheels? Does anyone know if they upgraded or anything?
Yes, complete new wheel design with significant improvements to take advantage of everything that was learned from Spirit, Opportunity and Curiosity.
And where is the nearest tire repair station?
Mark Rober will be very sad when curiosity meets it's fate
Is it made of aluminum (alloys of it maybe)?🚜
They should use Michelin or Pirelli tyres. 😂😂
Why did you delete my comment about how NASA was worried about excessive wear as far back as 2014? Well?
We're the dem spare wheel..then
Any tinker shop in mars?
I am thinking the tire companies should join nasa with new tires for future rovers!
It may not be long before some wheels become unusable. And that can bring the mission to an end.
Should have used titanium instead of aluminum.
How many kilometrs did that rover?
I wonder if AAA makes trips out that far to change the wheels?
This is difference of material quality between earth and Mars.
They use hardware and software from 40 years ago so it doesnt fail. They should do the same with remaining materials. All materials nowadays are shit from steel, inks and paints, screws, wood, everything is made to be as cheap as possible and to last the minimum necessary. My toy cars from 35 years ago still look in top shape, my mothers porcelain is looking great after 60 years and my secondary old car still has no rust.
When it's important enough and I can assure you those wheels and every other part on that rover are very important, there made with certified and traceable metal whose lot numbers have been laboratory tested. That ensures quality and that it's being built exactly to the tightly controlled engineering specifications. They don't just pop down to the local metal supply and grab something off the shelf. And no doubt any of the parts would get a variety of non destructive tests including X rays before the check gets signed. Above that, months to maybe years would be spent field testing prototype parts in earth based simulations. Maybe do a little research about metals used in aerospace first before assuming anything. Going by your logic, passenger aircraft would be falling out of the sky multiple times a day.
Just check the temperatures on Mars before writing dumb comments like yours
Would perchlorates cause enough corrosion to make the wheels weaker?
i've heard this is true
I thought that they would use an other material with memory. where is it ??, Στείλτε ένα λαστιχά. Θα ξέρει καλύτερα απο ρόδες
😢 Poor curiosity 😢
i wonder why they didnt use another type of metal, what about titanium? wouldnt it have been more resistant to wear? I mean i am sure the scientific team at NASA picked aliminium for a reason. I am just curious to know why.
@Mudkip909 but isnt titanium very light also?
What are the wheels coverings made of?
Aluminium made, and the same would happen here on earth, they should used rubber without air inside
@@MarineCy I was thinking a thick rubber would last longer too. But eventually runner rots. But would last longer than aluminum.
@@SchardtCinematic At -80° C on Mars, rubber becomes hard as iron and brittle. Certainly not a good idea
The rover designers shouldive consulted the RC hobbyist community to find out what wheels last longest
Wait! We knew about the wheel problem from previous rovers and yet still didn't fix it beforehand?
Ah that looks like something else
If one wheel loses a complete segment, so get flatspotted, it will stuck solidly, like the wheels on the rack of an old dishwasher. If this wheel-arm could be retracted, the other two working wheels must work 50% harder and collapse soon after. Obviously these wheels are not rotation (fatigue) tested on a real rocky mars-like surface (?) Go to Ford, ask them what to do.. Strange was the (Initial?) absence of a dust-off-brush for the solar panels on previous models. Mars is famous for its brown dust that collects on the panels. And we ARE already so far from the sun....every ray counts. A manipulator arm with a quick moving brush could do the job? Or a micro vacuum cleaner?
Is this true? One wheel has got damaged
They don't make-em like they use-ta!!!
Where is the night scene?
Seems like curiosity won't be able to drive in near future
Titanium is the solution but yes, this is what cutting corner get you.
It cannot maintenance on Mars when people arrive in here
they should do a pit stop
these are not Perseverance wheels. This is an old shoot.
Can you read ?
Ayay. the engineers forgot to put the hankook range😂
Is this so tragic? Haven’t those wheels a metal frame?
Who is the producer of these wheels?
The USA
perseverance don't have a spare?
I even wrote on one of the Curosity videos on KZhead that Wheels r damaged...It showed vry clearly...!Mars Terrain is terrible...!
Why don't nasa send a mechanic rover up there for situations like this
Yup...designed for a 4 year tour on MARS and still ticking after 10 years! Perhaps the best government investment in the history of the country.
For a moment i read "perseverance "😳
Well,they forgot to bring spare wheels 😄
It’s okay..still got more than 1.6 mm !
The first plastic soup on mars
rovere araç'a geçmiş olsun
Maybe peanut brittle was not the best choice.
What a shame. Hope it holds up. To bad you don’t have a pit crew to change the tires.
Why they dont put a little of rubber in the wheels for more durability? Just a thin aluminium will broke easily with the time
The bitter cold would destroy the rubber. However, it is doing the same thing to the aluminum. Also, aluminum after being exposed to the elements, does break down after time. That must be why they only expected two years of service from the rover.
I will never understand why they didn't use solid rubber tires.
Rubber wouldn't hold up to the extreme temperature variance anywhere near as well as metal would.
You're just forgetting it's -80° C on Mars. At these temperatures, rubber becomes hard and brittles.
And they're way too heavy. When you're leaving Earth weight is the most expensive thing. Rubber tires are fine on earth where a bit of extra weight doesn't matter, but when you're trying to get to Mars you can't pack on extra pounds, especially when they would break once you got there.
A KWIK FIT FITTER IS ON THE WAY LOL
Damn Walmart tires
this is not good I hope thay not push it hard I love this rover
Did you outsource those wheels from china?.
I heard they're sending somebody out to fix the tires
Yeah perseverance and ingenuity 😂
why couldn't they put a rubber coating of some sort on the wheels
Mars gets so cold rubber becomes hard as iron and very brittle
where's the spare
