It doesn't have many things around it to compare it to size-wise. Like it can't pull up next to an astronaut right now, nor to a mountain we can understand the size of. So no wonder a lot of people thought it was a tiny cute little robot, like a surveillance roomba.
For the record keep these facts in mind. - The rover was supposed to last 2 years, yet it still works 10 years later - Those wheel are supporting 2000 pounds (i think) for something the size of an SUV - This thing gets NO maintenance checks, because no people on Mars and all that
And yet for 2.5 billion USD. The cost of the rover. We get a 2 yr lifespan. And wheels that fail almost right after landing. Granted it's lasted 10yrs so far. But the wheels haven't completely failed because NASA spent MILLIONS more researching how to make them last as long as possible. It's things like this that constantly make me wish SpaceX had NASA's budget. We would have had a Tesla Roadster doing 60MPH and tires what would make tank tracks blush.
@TheAugmentedMan1 are you both idiots? Jesus christ, SpaceX has gotten more money than NASA for like 8 years and they've done literally nothing except get votes and catch a rocket booster (something NASA could do but decided against in the 90s because it's pointless to do)
@@Soulessdeedsthe rover didn’t cost 2.5 billion. It cost 2.5 billion to design it, build it, design something to get it there, build that, design something to land it safely, build that. 2.5 billion is actually extremely cheap for this kind of thing.

there's a delay in controls, they can never rush because they can't react very quickly if anything happens. the longest a cycle can be - 40 minutes. for example the rover sends some communication, about a stuck wheel or something, and then after the team decides how to tackle the issue - another 20 minutes for the commands from Earth to reach the rover

I don't know of any SUV that weighs just 2000 pounds. A Jimny weighs over 3000 pounds and that thing is tiny. The rover is still pretty large in size for something mobile that we've put on another planet.
The Mars curiosity Rover was designed to last for about 2 years. The fact that it's still working with or without damage after 10 years is bonkers. That's kind of important information to add when you're acting shocked about the damage on the Rover.
@@scottdandy2255those rovers are powered by tiny nuclear reactors. Things would get pretty crazy here if we did the same thing for our everyday phones and vehicles.
@@emrearslanoglu2735so you have a tiny nuclear reactor for something to be used millions of miles from home, is it not easily feasible to have a nano reactor on earth, one that would be near invisible in a standard sized mobile battery. Could it not be easily a near enough indestructible fuel cell like some memory chips that for the most part would be made up of shielding material and armour. Do we not already use radioactive material in devices such as smoke alarms, watch faces, with the units there self acting as shielding, and in some cases such as old cookware and lamp mantles highly radioactive with no shielding at all🤔
I’m pretty sure they have RTG’s onboard which slowly decay overtime which means if she doesn’t die from the weather she’ll die from her power source draining
@@Messup7654 Good question. The answer is that it is impossible to weigh something in free space, where negligible gravity exists. Put a bathroom scale under the Voyager space probe, it weighs zero! We are accustomed to thinking of weight as measuring the mass of something. In fact it only measures how much gravity is pulling something down. Gravity on Earth is constant so no problem in daily life. Everything has a mass of course but the only way to measure it everywhere is to push on it and see how fast it goes, from that we can calculate its true mass. So in this case, the craft weighed 2000 pounds, then at lift off it weighed 10,000 pounds while being forced upwards into space. Once on route to Mars it weighed almost nothing. The closer it got to Mars it started to weigh more and more based on its distance to the planet. Once on the surface it now weighs just 760 pounds. Just like a 200 pound man would only weigh 76 pounds on Mars, you could jump really high, probably 15 feet compared to about 5 feet on Earth. So weight is like what happens with distance. It's common these days to say a place is only two hours away. That assumes you drive there by car. That time estimate changes if you fly or cycle or walk.
Can someone answer this question please: is the rover traveling over 20 miles of terrain repeatedly for the past 10 years? Or did it take 10 years to travel 20 miles, going about 2 miles per year? Thanks!
10 years for 20 miles. This rover has to take directions from earth on where it goes, and what places to take samples. This is not like driving your RC car around right in front of yourself.
I'd also like to point out that the original rover curiosity was never intended to last this long. In other words the wheels did break down faster than they expected but the entire mission was supposed to be less than a decade long only a couple of years. Meaning of that Rover's been running way longer than anyone ever expected it to so kudos to the engineers
No surprised. Temperature fluctuations of over 150 degrees day to night can cause serious defects on materials. Very cold temperatures can cause objects become brittle and lowers the ductility
Lmao come on now. You know the government and these fortune 500 companies that are in bed with them always get the good stuff first for about 10-20 years maybe even 30
I always thought they were cute lil baby robots ever since I was a little girl.. you mean to tell me these things are actually TANKS?? My life is a lie! 😂😂
The curiosity rover has far exceeded its expected lifespan so people complaining about the wheels getting destroyed is just dumb. As an engineer you look at what is needed to get the job done for the given requirements, things like cost, availability, durability...etc. Plus, those wheels are not tiny, they are 20 inches in diameter.
But aluminium doesnt have a creep strength so while the engineers didnt do anything wrong they could use another material even without increasing weight all that much since aluminium is mostly good when you can increase the height around the neutral bending axis. They are certainly better engineers than i am but rp 0.2 is not the same as yeild strength. Not to even speak about ductility.
It costs thousands to send a single pound into low earth orbit. To send an extra pound to mars would cost hundreds of thousands not to mention the knock on effects to changing the mission parameters by having to adjust every other system of the transfer and landing stages to account for the change in weight. They did notice this error before the next rover, perseverance, was launched (it is largely the same chassis and drive system as curiosity) which is why Perseverence has larger diameter but narrower wheels made of thicker aluminum
Yeah i know weight is an issue but if you look into the material properties of aluminium it is quite shit unless you can extend the height about the neutral bending axis. That together with the rp0.2 problem should give steel a run id say. It was 1.5 mm i beleive you could have steel with .5 or .75 and probably achieve the same weight with more ductility and wear resistance. I dont have a Masters in tribology but i did take a few courses. Also i know how they solved the problem with hardox and dumptrucks. I think a mix of steel and maybe a rubber coating would work better, although there is some alchemy (chemestry) to factor in too.
Good idea, especially tortoises are “low maintenance” creatures and some breeds can live up to two years without food or water. But the real problem is that they’ve never sent a rover to Mars or any other planet, most of the videos are CGI and some just filmed in deserts with a fake Mars filter. Space doesn’t exist
Im no rocket scientist but if i were going to make wheels for a rover that weighs as much as an SUV, i would definitely make the wheels thicker than 1mm aluminum
Lower gravity on mars and it originally only had a 2 year mission. When they realized the robot was going to last much longer NASA extended the mission indefinitely for as long as the little guy keeps going. He's on year 12 of his 2 year mission so I think it's doing pretty good.
Then we are all glad you're not a rocket scientist. The rover was designed to last for 6 months to a year and every ounce of weight added to a launch makes it more difficult and more expensive.
I met one of the designers of the Mars rover who took pride in stating that the rover was design/ expect to work about 6 months but due to planning and positioning to catch sunlight to stay charged they(JPL) have extended it life.
Those photos of the wheels were taken a couple years ago. It’s old news for an avid follower of NASA mars news. they actually have a plan in place to operate on a reduced wheel surface area by actually using the environment and curiosity’s tools to intentionally cut off the inner 2/3’s of the tires.

Yes because we are talking about an iron object millions of kilometers of distance , that has an extremely limited action pool due to the need to keep energy. They are not sure about anything because they can not be sure about something millions of km of distance
Curiosity Rover... good name... Just like I'm curious on how the battery operates in -125 ° temperatures. Or how it charges in those temperatures. Or how it even lasted a decade in those temperatures... We can't even figure that out on Earth yet...
Kevlar degrades under the radiation/UV exposure levels on mars, titanium is heavier than aluminum per unit of strength, and most materials that would work better are prohibitively expensive or heavy
I feel like they shouldn’t just change the design but maybe change the material maybe like a tire made of a material that can absorb the shock and that can bend with the terrain instead of the terrain breaking through it for instance a rubber wheel with no air. Not saying they should use rubber because I’m not sure if rubber would work for the atmosphere of mars but a material like that, that could withstand the mars atmosphere.
Oh yea your opinion is the best. Better than the 60yr olds doing this all their lives 👏 somebody give Nasa this female’s number. Elon Musk would like to get placed on your busy schedule too. Wait wait There is 86 nations around the world that would like your input into their space wheels. They said your intellect is out of this world. The king of rubber also called
Is it not common knowledge how tires are made and how they work on Earth? If you know that you can't drive an SUV 20 miles on aluminum rims without having the rubber tires then you already understood that the difference in gravity is why those wheels lasted as long as they did. Though it isn't crazy at all, she did make the assumption that common sense is common 😂 For children under the age of 15 and those who forgot what they learned in drivers Ed, she could briefly explained "heavy...thin wheels... lower gravity" but it's actually very common to believe that common knowledge is common.
Mars atmosphere, solar radiation, and extreme temperature fluctuations will destroy any tire in 10 days. The fact that it lasted for 10 years is impressive!
Weight is a primary concern for a spacecraft. While titanium is light, it’s still nearly twice the weight of aluminum. The engineers developed a design based on known parameters. Once there, they discovered that the rocks were sharper than previously believed, which caused more damage than anticipated. They used this information for the Perseverance rover and used an aluminum/titanium alloy for the wheels.
To be fair, there isn't anyone to make repairs to the Rover either so all that wear and tear with minimal damage isn't to bad. From what I understand they're in the process of making new tires specifically designed for the Rover so it can better traverse the terrain on Mars. They're also supposed to be much more durable as well 👍🏻
Mars is not a star. The rovers were made to do tests on Mars. The nearest star apart from our sun is too far away. to reach it with current technology will take thousands of years. NASA is figuratively shooting for the stars but not literally. That's impossible.
Yes they are less than a millimetre thick. You perceive it as more because it has threads, stiffening rims, and outer rims. You can look at the damage photo and see how thin the skin is
How does a rover keep moving over a decade ???? Does it have solar panels i dnt see any ?? Is it electric hybrid ?? Does it charge as it goes ??? 😮😮😮 sumkne explain ??
A RTG, aka a very small thermonuclear reactor. It uses small amounts of radioactive material which decay and release heat which heats up something which turns the heat into energy. Or something like that, idk it's been a while since I've seen a blueprint of one.
I remember seeing a video showing their new for specialised airless tires. They are made of a mesh and have an internal plate to prevent them from being pushed past their plastic deformation limit.

I know but you know how many budget cuts NASA has to deal with all the time 😔
Michelins are so expensive, though.
Yeah, gas filled tires in space (or on a low pressure planet); what a brilliant idea 🤦♂️
@@Fenrirs_Ghost lighten up Francis…
@@Fenrirs_Ghost not sure you realize that we're joking..
Please use the metric system. Only three countries don't use it.
I forgot my toy car on Mars
They are shameless
Why use weak aluminum and not something strong, like titanium?
I'd suspect that weight is the issue.
It's probably not just plain aluminium it's likely some engineering alloy
I'll take this as a dad joke.
Ti is right next Al and it has roughly similar mechanical properties, etc Ti is more brittle in cold.
the new material they're using is a Nitinol wire mesh, which is flexible and damage resistant. aluminum was just the go to back then I guess
They also say they don't go to the moon because we "lost the technology" a nasa engineer said this on camera
I wanted to give you a hi 5 at the start of the video. Really.
Insecurity comes to mind
Your insecurities about high fives or what?
😂😂😂😂😂
You look like a model. Your face is perfect.
Yes she is distractingly lovely so I have to look away and just listen to get the info-
20 miles in a decade? That ain't nothing. I've put almost 3,000 miles on my Honda CR-V since I got it a month and a half ago
Is Kevlar, titanium, or some stronger material not an option?
Kevlar degrades under the radiation/UV exposure levels on mars, titanium is heavier than aluminum per unit of strength, and most materials that would work better are prohibitively expensive or heavy
No one cares about expensive. Weight is a huge deal,,since it’s gotta go up and come down.
@DrDeuteron You overestimate NASA's funding level
They never expected them to last this long for it to have been a problem
@ … Price aside, is there a material that would have been better to use for durability?
The only reason I want us to go to mars is for the robots to finally be recovered after their inevitable death of a journey.
Robot lover
Samsies bro
Also keep in mind it's mission ended a very long time ago. This is all just bonus data. So cool.
This rover a million miles in earth car milage. Very reliable.
I feel like they shouldn’t just change the design but maybe change the material maybe like a tire made of a material that can absorb the shock and that can bend with the terrain instead of the terrain breaking through it for instance a rubber wheel with no air. Not saying they should use rubber because I’m not sure if rubber would work for the atmosphere of mars but a material like that, that could withstand the mars atmosphere.
Oh yea your opinion is the best. Better than the 60yr olds doing this all their lives 👏 somebody give Nasa this female’s number. Elon Musk would like to get placed on your busy schedule too. Wait wait
There is 86 nations around the world that would like your input into their space wheels. They said your intellect is out of this world.

You should work for NASA. I’m sure they never considered that.
@@ckchatta369 geez. Relax, bud.
Sure. Let us use this magic material of yours.
@@ckchatta369 No need to be rude like that. One can think by themselves and challenge others as long as everyone is opened to listen and learn.
Saying a weight while not considering Mars’ gravity is crazy 😂
Is it not common knowledge how tires are made and how they work on Earth?
If you know that you can't drive an SUV 20 miles on aluminum rims without having the rubber tires then you already understood that the difference in gravity is why those wheels lasted as long as they did.
Though it isn't crazy at all, she did make the assumption that common sense is common 😂
For children under the age of 15 and those who forgot what they learned in drivers Ed, she could briefly explained "heavy...thin wheels... lower gravity" but it's actually very common to believe that common knowledge is common.
I imagine the rover's internal monologue is like one long roar of MORE SCIENCE!!!
Mars atmosphere, solar radiation, and extreme temperature fluctuations will destroy any tire in 10 days. The fact that it lasted for 10 years is impressive!
It's not a tire my guy, It's a metal wheel.
It's hardened aluminum, but I can see the severe windstorms on Mars cause the wheel to erode.
@@johnnyk.2911 i think you mean sandstorms, wind doesnt do much under 100 mph
Should have used titanium for the wheels. Aluminium is too soft.
Sounds heavy
Beryllium would be much better.
@@willjackson5885 titanium is actually a light metal..
Weight is a primary concern for a spacecraft. While titanium is light, it’s still nearly twice the weight of aluminum. The engineers developed a design based on known parameters. Once there, they discovered that the rocks were sharper than previously believed, which caused more damage than anticipated. They used this information for the Perseverance rover and used an aluminum/titanium alloy for the wheels.
@@Until_It_Is_Donestill 2/3 heavier than aluminum.
I thought you were going to tell us that someone or something damaged the wheel for a sec there haha😅
"🤓 that is a giant hole in the wheel" lady I got eyes 😂😂😂😂
To be fair, there isn't anyone to make repairs to the Rover either so all that wear and tear with minimal damage isn't to bad. From what I understand they're in the process of making new tires specifically designed for the Rover so it can better traverse the terrain on Mars. They're also supposed to be much more durable as well 👍🏻
"Curiosity" & "Perseverance." NASA really be out here like that. Literally and figuratively shooting for the stars.
Mars is not a star. The rovers were made to do tests on Mars. The nearest star apart from our sun is too far away. to reach it with current technology will take thousands of years. NASA is figuratively shooting for the stars but not literally. That's impossible.
I always love how she covers the photo for the reveal. 😊
I hate it 😅
Definitely for the reveal
It's probably in the inner city part of Mars.
oh no poor thing :(
This is so sad :(
lol... it had to travel 140 million miles from earth to get there...
- yet... those extra 20 miles were the toughest part of the journey...
It is an inanimate object
@@ReinaPerez-l3q so is a house yet we all want a house
@@half-deteriorated-brain
We don't say anthropomorphic things to it
NASA: we're going to over engineer a heavy rover and put aluminum foil wheels on it
It's ridiculous
@@JoeAnthony-k4vto be fair they expected it to last only two years soooo…..
its strong and light aluminum going over the most rough conditions imaginable
Ok buddy show us your resume really quick 😂
@@Brogon_the_10st hold on, let me type it up and print it out...😄
Devon Island gets rough for RC cars 😂
If you know. You know. If you don't know, you're complicit, gullible, or fearfully lazy.
Yup! I was thinking Greenland or some desert island.
I know you’ve tackled obstacles even bigger than 26 inches
The wheels are less than a millimetre thick ? Yeah I don't think you know what 1 mm is lol...
She knows how to wave her hands very well.
I think she read from the data they show, it has .75 mm thick.
Yes they are less than a millimetre thick. You perceive it as more because it has threads, stiffening rims, and outer rims. You can look at the damage photo and see how thin the skin is
They are tho...and its fine, cause of mars's lower gravity and it having 6 of em...
Over a decade and only 20 miles…
“Erm actually that’s super impressive 🤓👆”
😂
Say what you will mate I font think 20 miles on Mars is too bad
More impressive then anything you'll ever do lol
try it yourself, dont think you'll even get off earth
^^^ Look, a crackpot.
My dream is to go to Mars and hug all our rovers that have served us. 🙇♀️ 🥹🤗
Bring some tools!
Can you get a visa?
Seriously we should have been terra forming mars a long time ago
Bro was the first child, the experimentation phase 😂
We gathered there’s a hole in a wheel somewhere? The rest my wife and I couldn’t retain attention. But I love space and the respect you have for it!
Now I know Wall-E messed me up good cuz I immediately thought, "Oh no! His foot is damaged!"
Your makeup is so pretty😊
I still think they should have had a group of rednecks engineer that thing.
You seem very excited with the info they provide to you
One day we will go to mars and recover these amazing machines and they will be in a museum for all time.
Should've gotten an aaa membership as a tow truck driver we always show up no matter where you are. XD
Quality planning, Quality work, Quality results!
As far as I know curiosity has far outlived its expected lifespan
Niga only travelled 20 miles and now giving excuses.
How does a rover keep moving over a decade ???? Does it have solar panels i dnt see any ?? Is it electric hybrid ?? Does it charge as it goes ??? 😮😮😮 sumkne explain ??
A RTG, aka a very small thermonuclear reactor. It uses small amounts of radioactive material which decay and release heat which heats up something which turns the heat into energy. Or something like that, idk it's been a while since I've seen a blueprint of one.
@TheSkookat radioactive ?? Im research thank you sir
I remember seeing a video showing their new for specialised airless tires. They are made of a mesh and have an internal plate to prevent them from being pushed past their plastic deformation limit.
I feel old, I remember when I cheered for curiosity, when it were news
The idea of some other sentient species coming across the rovers one day is wacky
Sometimes I think about the rover that sang itself happy birthday as it was dying and I tear up a little ngl
I love Mars. I know it gets a bit windy there, but still, it looks peaceful.
Well , since somebody down there in that planet to replace it
*LOL* the next mission is to change tires? Those rovers are super cool! They did miracles.
When both rovers meet up on mars curiosity is gonna be pissed about its siblings upgrades.
When people question your progress in life, just tell them about curiosity, that is the mindset and the rover.
I was just about to comment that the wheels were the first improvement they made for perseverance
Whats crazy is for some reason i just want the two rovers to roam together ❤️
Keep in mind it only moves at about 0.1 mph
Dang thats fast
Who knew cutting weight at all cost would have some set backs. When the primary failure is the thickness of the wheel.
