This didnt age well lol. They could have asked us racing and fpv drone builders for advice , we coulda sent a sortie of drones doing the same thing in the space of that......THING

but i thought mars didnt have air, how can it fly?????

Don't anyone ever say to me, that there no such thing as American Exceptionalism , what would you call this??

Why did they do the complex pulley system to offset the weight instead of taking the batteries out and reducing the weight that way? Is there something I am missing? Maybe they want to test the entire system without any hardware modifications I suppose?

This will not be the first powered flight. Technically, the sky cranes that lowered the rivers safety to the ground in the last few rover missions have been the first powered flights on other planets.

No it is not ....

NO, Its in ur hand

@2:00 he's comparing a helicopter to a drone(RPM): Parrot AR Drone 2.0 motor - Range of these motors begins at 10,350 RPM and it goes up to 41,400 RPM.

So, they are spitting, touching, this device without proper protection to avoid microbial residue on another planet, interfering with future discoveries mixed with our microbia. am I crazy or something to think about this?

That’s not the one that’s actually on Mars

Also note that the speed of sound on Mars is lower than on Earth

I watched the prop test of this craft a year after this video was uploaded. Epic!

As a FPV Quadcopter pilot, this gets me all excited & nerded out.

Its not first drone Its first Air drone. Dont forget the satalites, the rovers and mini shuttles.

Nobody did it so I had too "MARSCOPTER GO BRRRRRR!!"

Good 😎

How does it cope with the extreme temperatures on Mars?

It's explained in the video, it uses energy from its battery to power up heaters.

@ThiccDuck 95 Well, that depends on the season. Mars's atmosphere is about 100 times thinner than Earth's. Without a "thermal blanket," Mars can't retain any heat energy. On average, the temperature on Mars is about minus 80 degrees Fahrenheit (minus 60 degrees Celsius). In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).

its just 0 - -100 degrees cold thats not extreme for robots:D

wonder how much cost tax payer that NASA have build bigger version of DJI drone? ;)

better way is a cage around cause is it fall on side it finished

The first flight is going to take place day after tomorrow!!!!

Would the speed of sound not be slightly altered if said speed is in a less dense atmosphere ? And would this not alter the speed at which the rotors are able to rotate?

The speed of sound does not depend on pressure, but it does depend on temperature and the elemental composition of gas. It will be -50C on Mars during the flights, and the atmosphere is largely carbon dioxide instead of mostly nitrogen on Earth. People at JPL know all that, and when they talk about the speed of sound, they mean the speed of sound on Mars.

Great video, it was very cool to see and hear the creators of Ingenuity! But I really wish you would not have said that _"on Earth helicopters spin their blades at 500 rpm"_ (to contrast it with how fast Ingenuity's blades spin 1:45). It is indeed a very intuitive thing to say that Ingenuity flies in the thin atmosphere of Mars _"because its blades spin crazy fast"_ but the reality is much more subtle. The helicopters on Earth spin their blades in a very wide range of rpm, depending on the size of the helicopter -- from below 200 rpm for the large full size helicopters, to 8000 rpm for DJI drones. If we compare Ingenuity to the RC helicopters of equal size, we would see much more similar rpm. RC helicopters with the rotors of the same 1.2 meter diameter as ingenuity (550 or 570 class) spin their blades at 2000-2500 rpm and even faster for some aerobatic flying. This does not, of course mean that Ingenuity is just another off-the shelf RC helicopter -- or course it is different in many parameters! But even though it seems counter-intuitive, the rpm is not one of these differences that make it fly on Mars. It would be more meaningful to say that the very wide and specialized rotor blades of Ingenuity could lift it on Earth with just 500 rpm (if it had sufficient torque, strength etc). Then, 2500 rpm on Mars is indeed very fast in comparison.

Wow cool! I have a video of Ingenuity's first rotor spin test on mars live now

La wea wena weon o

I had remembered that 71,000 feet above Earth is the same as the lowest spot on Mars?

That’s insane if true. considering that at 71,000 feet there’s almost no air up there anymore, and to come to realization that’s equivalent to the lowest point on Mars? damn, this stuff is so interesting. yeah we definitely cannot go on Mars without protective suits.

I SOOOOOOOOOO LOVE THIS CHANNEL

if the atmosphere is so thin in Mars there would be no blades sound like the one in the animation, or not?

@How Does it Really Work beautiful, thanks!

It is not an animation. It is a test of the actual helicopter in a room where air has been pumped out to create conditions exactly like on Mars. And that was how it sounded.

Que sorte a minha. YouTube me presenteou com este vídeo altamente explicativo a respeito de Ingenuity. Desfez minhas dúvidas. Obrigado a toda a equipe do vídeo. Espero agora pelo 12 de Abril. Go !

The guy in the red polo is like a nerdy Gronk

China greatly appreciates all of the new intel from this project😏

No return to rovers belly at night for food and shelter ?

No

I love how they committed to hireing scientists from a diverse hight group....

What a liar! The copter is obviously in a lab on earth, NOT on Mars! They think we will believe ANYTHING they say!!

On mars now

what is purpose of called chinese weight?

@How Does it Really Work thank you for answering

It compensates some of the inertial forces and makes it easier for the servos to move the blades.

This sounds so bs. Just saying... I don't believe it.

You can believe what you want. That doesn't change the facts.

What about this is BS?

Very soon

It about to fly now

If Gronkowski stayed in school

get it off

On the topic of going to Mars the necessity to drink pee rarely comes up

Astronauts recycle urine every day with no problem

At least they don't have to worry about flyin the drone in to any trees .

OR power lines.

You have change the title of the video for more views , in 2019 ''this helicopter'' was not on Mars. Why have you done this ? I think you and your videos are very popular and you don't need this trickery...

I'm curious as to why they didn't just attach the fishing line, through the pulley, to something 62% the weight of the chopper... surely that means that the amount of weight it has to lift is only 38% of its original weight

That would only work perfectly when the helicopter does not accelerate up or down. If it does accelerate, then the actual mass of the helicopter plus the mass of the counterweight would be accelerating, and that would require a factor of (1+2/3) more force vs just the force to accelerate the mass of the helicopter itself. So the dynamics of the altitude control would not be quite the same. I do not know if that was important or not. One could also imagine using a long rubber band to pull the helicopter up with a force that is approximately constant, but that would also not be quite as perfect as the more complex system which they have implemented. It would be curious to know if there was some really important reason to do it the way they have done it, or if people at JPL simply have a habit to always do things in the best way possible.

Wait, did the title changed?

Then why cant they use thrusts instead of fan blades ..

Thrusters would require a constant supply of fuel. Using rotors that are moved by electric motors ( powered by rechargeable batteries) is much more "fuel" and mass efficient.

Asians are on this project? How would ppl hate asians on this monumental event

This video takes on new significance now that the copter is on Mars ready to fly it's first mission.

Yesterday marks the first public video footage released of the propellers spin test!

Plot twist: Ingenuity was deployed yesterday and has survived its first night on the martian surface!!! Exciting times!!

Plot twist twist: ingenuity failed its teest spin and now the flight has been pushed back

The 5 th day

​It would be interesting to find out if there are any plans to send inflatable Zeppelin to the Mars , they could use Kevlar encased durable balloon and flexible solar panels for power , so is would be easier to observe larger areas

Vacuum zeppelins are possible on mars

Either you got so high you've forgotten what species you're a part of or you need therapy

@Lucifer You, you are on drugs (or need psychiatric help).

Looks like a drone not a helicopter

@Zeen Daniels I mean, nasa call it helicopter so why contradict nasa

It's both... Actually

still helicopter

The helicopter drone is going to fly on 11 april 2021😍😍

04:15 Wow, CBD did wonders for Gronk.

And now, few days left till take off. Congratulations to the creators of first helicopter on Mars!

Ir might have lift of by today

Noice

Perseverance rover has already found signs of mOre intelligent life on Mars than a flat earth conference.

The Ingenuity on Mars has some really cool spring leg joints that are missing on the Ingenuity shown here.

On Mars one year ago ??? 🤣😂🤣

@Jimmy Bond the helicopter is on Mars though, not clickbait

@Jimmy Bond LOL 😂

Ahh so it was a lazy click bat attempt !!! 🤣😂🤣

I think he changed the title.... Use some brain

in its first low level flights wont this kick up so much dust that photography would be impossible, and will the solar panels be affected by the dust

Anyone who flies RC helicopters knows this is pseudo scientific fantasy!

@Zeen Daniels You needed to hear, denied.

@Aled Long So you can't. You just needed to say that...

@Zeen Daniels Asperger's???

@Zeen Daniels Dude??? What are you hiding???

@Aled Long Dude... Just do the maths of shut up. Your choice.

Ah, to be paid billions to horse around with drones in space......... Nice work, if you can get it.

His sexy collar is his security pass. What’s his sign? “Right on, man....”

Is the baldes weight 4x35 g or 2x35 g? (2:57 min)

4x35 g, but that is just the "paddle" part without the root with the chinese weight, horn, and the bearing. With the hardware, the blades are about 4x45 g

Cool! I love watching this, thank you!

They should have contacted Boston Dynamics and put a 2 leg robot on the surface instead of this rubbish.

Honestly... how f***ing awesome is that?!

they could use a spring mechanism (kinetic propultion ) so that its shoots up and take photographs from higher altitude

"it's swimming in a think soup" but in that same thick soup we could be able to fly drones and other. could you through some light on it. is it not like a very small, light weighted insect flying.

Amazing!...in my lifetime. I barely rememberJohn Glenn, then my first real introduction to death when Grissom, White, and Chaffee died in the fire. Now we are FINALLY back in space and not just pussy-footing around.

80 million dollar drone .....

15:35 maybe rovers will be the future companions to aircraft

Why does this copter look suspiciously like it's going to be playing golf instead of doing work on Mars?

​@Bobby Vincent I guess humour doesn't always come through in Youtube comments ;) Let's hope the craft will do ok, and Percy will deliver some sick pictures and vids of drone flying!

@Hubert Marciniak I was just making a joke about the golf club lookin legs. It's only in the air for like what 90s ....... it does what it does and I'm quite sure it will do a great job and be well worth the trouble of all the work they put in to get it there

@Bobby Vincent If the craft is light enough, then I suppose it doesn't need big beefy legs. Besides, it won't do any serious work. It's "only" goal is to test if such a drone/helicopter is a viable way of exploring Mars (and take a few pics along the way/test the navigation software). If it succeeds (meaning: it will be able to lift off, control it's flight and land), then it will create a path for future, more advanced crafts.

@Hubert Marciniak it's legs look like '5 wood' golf clubs

What is so suspicious about it?

This guy has unrestricted access to the entire world

Flying a helicopter on Mars proves that an atmosphere is present on the red planet.

~1% atmosphere

Nothing new, really. The atmosphere of Mars is a fact known for more than a century now.

Wow

3:33

Sound of helicopter: "Baaaaaaaaaaaaaaaaaaaaaaaaaah" 😂

Worst thing you can send to mars a helicopter.Worst thing contra rotation version for very obvious reasons.

@BILL POWER ?

@DarkLight 2.1 My own.

What video were you watching? LOL

The secretive debtor daily compare because fork ultrastructually cycle up a best step-sister. tough, vast grain

The evanescent color biomechanically confuse because marble interstingly offer alongside a purple judo. aquatic, cuddly berry

I saw the title and I knew he had updated it. Nice!

Hey why don't they just simply use the the battery of the mars rover at night to keep the mars glider warm and charged at night as that would be attached all night with the mars rover and mars rover could also charge the glider much faster and efficiently... By this they could be able to fly twice the time as normal... This would be as a parent parenting its child 🧐😀

Connecting the two vessels would be very difficult

Damn.......... it must have been awe-inspiring standing that close to it and then seeing the images from Mars. ;)

I would HATE having to rely on some explosions to flip the helicopter right-side up onto the ground. I know its all calculated by people that actually understand this stuff but still that has to be nerve racking because its not like you can just pick it up...

a minute and a half of flight a day if everything goes perfectly.... lol while that's not much it is kind of impressive.

to sum-up you guys can guess if NASA dudes make the same efforts to tune a helicopter that works on Earth 😂

What happens at the next storm though?

Big day for Ingenuity coming up on April 8th.

They talked about the blades staying below the speed of sound, it is different on Mars. However, I don't think the issues of transonic flow will be as drastic with such a thin atmosphere.

They designed it for the parameters of atmosphere on Mars, and when talking about the rotor speed they meant that it was rotating at 0.6 of the speed of sound on Mars. (Which is about 240 m/s)

sure but why risk it

How is the Earth's magnetic field protecting life on Earth from cosmic radiation in the form of gamma rays if gamma rays are not deflected by magnetic fields?

It doesn’t. But the atmosphere does.

This Helicopter Is Now On Mars!? well yes it is now in 2021 but back in 2019 no it wasn't

he updated his title after the landing

7:45 youre basically programming macro's for the helicopter esentially ? just like you could in a pc game ?
