Chris : Damn dude. Temperature, hardness, strength, elasticity, microstructure, mass, diameter, width, thickness, life expectancy, speed, radiation levels, gravitational constant, natural terrain... This wheel’s design has more parameters to worry about than an introverted engineer on a date with a model.

Cziffra : 3:45 jesus can you imagine having the memory of riding a dune buggy on the moon? nobody can top that

Drake Shattuck : How NASA Reinvented the TIRE.

Anders Rullestad Eriksen : But will it blend?

II : Why not build wheels made of Nokia phones?

Xander Lowe : It's crazy how just simple everyday things on Earth are so different in space and it really just makes everything harder

Capissotor : Early BC -Wheels 2019 -Spring Tires 2050 -Floating wheels

Mohamed Elsaid : He says "mars" like a frikken pirate bruh

MaxBrix : How NASA reinvents the wheel - Goodyear invents a new tire.

Matin Far : I can't believe you just assigned homework to all your viewers xD

wiwbiz2 : Man, if you ask this guy to promote a jar of jam, he'll make it so serious that you'll think you're not eating jam ,but something like accomplishment of humans' imagination on reinventing the taste structure of fruits. Damn it feels so serious..

Robert Hahn : "This material remembers it's original shape. Here's how it works: ... When it cools down, it remembers it's original shape and returns to it"

Stephen Walker : They didn't reinvent the wheel, they reinvented the tire. Also, for the record, the wheel is not as simple as people think. It's nothing without an axle, and doesn't work nearly as well without bearings.

FabioST : Tough place this Meerrrrrrhs, almost as tough as Mars

JohnnyBadboy : I can’t believe you got sponsored by such a prestigious organization. Great job!

flat world : Celebrating an animation GGI LOL

天楽 : Before watching: yeah, yeah... just another clickbait advertising a new material, give me something new plz. 7:43 WE ARE LIVING IN THE FUTURE!

imso b0red : what if curiosity went into a storm and a rock hit it would be ok?

Michael Raimondi : "The Mars rover cost $2.5b to develop and it employs a nuclear reactor for power." Not true. Curiosity, like almost all nuclear-powered spacecraft, is equipped with a radioisotope thermoelectric generator (RTG). RTGs generate electricity from the decay heat of nuclear fuel, whereas nuclear reactors "burn" their fuel by controlling a nuclear chain reaction. RTGs and reactors may sound similar, but they're about as different in principle as a battery is to an engine.

Trump's Dingleberries : That's why we need to invent flying cars.

J. Xochimitl : All your ideas are belong to us! And hey! You'll be working for exposure! You'll get lots of experience!

NO_VALUE : Wheel 2.0 presented by NASA will have battle royale mode. He soundtrack will be despacito 2 and Africa by Toto (These memes are dead, yet i still wrote this)

chris p : How good year helped NASA reinvent the wheel.

Bass & Beyond : mers

Dr.KarMichael And Jones : 8:08 I just realized you have an Irish accent

Samuel Yap : although you don’t have many subscribers, you are a jewel to us who look forward to learning something new with every video. Thank you, and please never stop

Mick Smith : My Aero class presented our senior design project at JPL last march and we got to speak with one of the mobility engineers for the Mars 2020 Rover. They told us that there were two main flaws with the old wheels: the grousers (treads), and the placement of where the hub attached to the wheel. For the grousers, their design was to give better traction by increasing the length of the grouser, which is why it’s zig-zagged. Consequently, having those ‘zig-zags’ meant that all the stress from the rover’s mass was concentrated at the vertices of the grousers, and if the force was high enough the stress concentration would puncture the wheel frame. For the placement of the wheel on the hub, it was mounted offset from the center (laterally, not axially), so that the wheels extended out a bit further from the rover chassis and suspension system. This was an issue, because it basically meant the exterior rim (the part of the wheel that’s furthest from the rover) wasn’t being properly supported, and the forces on it were like the forces on a cantilever beam. This causes it to bend slightly, and over time this constant bending fatigued the wheels, adding more to the damage caused by the grousers. For the 2020 rover, they plan on using similar wheels to Curiosity but with the hub mounted in the center of the wheel, and using a sinusoidal grouser pattern rather than a zig-zag.

Seb Luna : You sound like RT Game

Random Person : So you just got sponsored by the RAF and BAC!! That's that's insane

Marc Boutilier : you know, maybe someone can use the huge temperature difference of the surface of the mars and below ground level to generate electricity. Like an efficient Peltier.

Sailor376also : Aluminum is a near useless designation. Which alloy? There are hundreds of alloys and the strengths from one to the next covers much more than an order of magnitude.

Carter Stong : Rip mars rover

armando dane : This Video should be titled: How Goodyear Reinvented The Wheel - Shape Memory Alloys Give credit where credit is due...

killernat1234 : The episode of wheel engineering...

R.A. Monigold : You are a valuable source of solid information for "the rest of us" (two compliments in a row). Thank you for sharing...

Grim Reaper : "Mers..."

Dino Dan : RIP curiosity rover 😭😭😭😭

Salah Haji : CGI LEVEL: Maximum reached

Chris Davies : It does NOT use a nuclear reactor to power itself. It uses an RTG - a Radio Thermal Generator, which converts the heat from a decaying 5-kilo slug of plutonium into electricity using peltier devices. It is not very fancy, has no moving parts, and is very reliable, but low power, at less than 110 watts total output.

Buck E : So they didn’t reinvent the wheel. Classic click bait. Your better than that.

galaxymoto : So give us your idea's !, coz we is got no idea. Right. How About no.

evo eve evo : All this to get heavy funding in the name of space exploration

jed Rudolph : I think it's worth noting that this 1 tonne (assuming metric) vehicle would be roughly 400 KG on mars (roughly 0.4 Tonnes).

Adventure : Just slap some Flex Tape over that rover boi and we’re good to go.

Kenneth Kustren : Yes... We did reinvent the wheel. ITS CALLED AN AIRCRAFT. Can you say HOVERCRAFT... also WING IN GROUND EFFECT... AND THEREAFTER... HYDROFOIL

marouane jamal : why not sending a drone

huynh duc le : Hey dude, great video. I learned alot from it. Just a little advice, slow down your narration and pause once in a while when you introduce new informations. At some point, it sounds like a long paragraph without punctuation. Anyway, awesome vid dude.

Nick Voutsas : 3D printing will become an important factor in repair and development of components on Mars

PanzerDragon : Just use flextape and nokias, there, indestructible.
