Gyroscopes in space
ฝัง
- เผยแพร่เมื่อ 20 มี.ค. 2016
- Gyroscopes form an important in keeping the International Space Station and satellites pointing the right way as they orbit our planet.
ESA astronaut Tim Peake shows how gyroscopes can be used to keep spacecraft stable during his six-month Principia mission.
There is no up or down in space. Satellites track their pointing direction using the same approach as on submarines and aircraft: fast-spinning gyroscopes that maintain a fixed orientation in the same way as a child’s spinning top. The International Space Station has four big gyroscopes which are used for stabilization of the Station.

Just look how amazed he still is with this "toy" and the physics behind it. This enthusiasm and childlike curiosity is what you need to become a successfull scientist or even an astronaut. Greetings from Germany and keep up the good work.
There is an actual photo of this guy in front of blue screen while he's supposed to be on board the ISS. The gyroscope is on a string. You see it at 0:32. Notice how he doesn't allow the microphone to float.
@@beckydoesit9331 The moon is made of vanilla ice cream.
First time I saw your comment I told myself that replying to such nonsense would only serve to make me dumberer. But, months later, I've come across it again, and, well, at times I'm a self-sadist.
That infamous string is part of the gyro toy, you suckafish. One wraps it around the center axle, pulls it, and thats what starts the inner wheel of the 'scope spinning; it is not attached to the toy nor is the toy suspended from it or any other string, foolia.
And your brilliant microphone debunk point? When one is taught how to use a mic, one is always told not to bump or rub it because thats amateur hour booshite and besides, sound techs will curse your children. He didnt let the mic float because it's difficult to get a NONGYROSCOPICALLY STABLE item to remain in place at very low 'zero' G...the exact thing he was demonstrating, rubette.
Galileo had enthusiasm but there was this Catholic Church...😅😅😅
Nice! But why couldn't he just levitate the microphone right in front of him for the time it took him to spin up the gyroscope, like a boss? ;)
if you look at other videos you'll see that stuff they "drop" always has a tiny movement left and it drifts away... it seems to be pretty hard to make an object stay still
Electro phobia That's why I said "like a boss" ... pfft, those space rookies and their velcro ;)
+Penny Lane You are right, he coud have tried to spin the mic, in order for it to be stabler... like a boss
E McA That's the spirit!
I think he's come to terms with the fact that microphones definitely DON'T stay where you leave them in 0g
I was wondering about whether gyroscopes have precession in zero gravity. I assumed they would not precess but wanted to see that in action. So, I'm happy to find this video. More like this please!
That's absolutely amazing !
its so nice that we live exactly when we can see such a thing..
Amazing. I never knew about this phenomena.
lol the string got stuck
Does anybody body else see Megatron's face in the background?
Spinning things in space, amazing
How does the internet work in space?
slowly
+Kirill Holstov works fine :)
+Kirill Holstov you need a loooong cable
+Kirill Holstov Don´t u have internet on your smartphone ?
+Kirill Holstov
It is beamed to a geo stationary satelite at ~30,000km above earth, where it is then beamed to Houston in Texas, where it is then managed further. There is no direct internet access on the ISS, everything goes through Houston (Due to the risk of viruses and cyber attacks).
Awesome! I love physics!Thank you Tim!Greetings from Argentina!
I think that's the same way how planets are stable.... the same grade of inclination and riding around our sun...
would you see that tumble if you'd let it go for an hour? because the space station rotates end over end once per orbit to keep the cupola aimed down and that gyro would not do that
that's an interesting question, i'd think that too
***** you've got your facts wrong. The station does rotate in order to keep the cupola aimed down and the solar panels aimed to the sun.
***** the moon also has the same side pointed towards the earth and it rotates to do so. what makes you think that the space station doesn't rotate for the same effect?
***** ... it doesn't rotate relative to the surface, yes, but as far as i know the surface is circular. Soooo ? Just grab a pen and do an "orbit" with it around a central point while keeping the pointy side towards the center (like the cupola aimed towards the ground) and OMG you have to turn it around in order to do that.
Is it really *that* complicated ? If the cupola is always pointed to the surface, then it also points in the opposed direction every time the ISS is on the other side of the earth.
whoeveriam0iam14222 no, the moon is tidally locked, it's because the closest side is more attracted, after a looooooooong time the rotation pace becomes equal to the orbit period.
This is not the case on the ISS, it takes a very long time because the closest side is only a very little bit more attracted. That's why there is a reaction wheel system to keep the cupola pointing down
Can you imagine if that were a Beyblade toy? That'd be the coolest Beyblade battle ever!
Where does the gyroacopes sit on the station?
Looks like the same movements small UAV or ‘probes’ that fighter pilots see going so fast while changing directions.
⭐ I had to watch this because I imagined a spaceship that used a large gyroscope to produce energy and I wanted to know how it would behave in space... Awesome video, thank you...
saaaaaaaaammme
@Jeffrey Dohnger thats very true, but in space there's almost no friction so it seemed like you could use the gyroscope to generate some power... I got the idea from somebody that suggested applying a magnetic generator to the axles of an electric automobile to partially charge the vehicle while it's moving... It's definitely more of a secondary power system, it just seems like any electricity you can generate in space is better than nothing and if you can increase efficiency by using a gyroscope for two purposes, that it wouldn't be a terrible idea... since space craft already use gyroscopes to maintain stability, you might as well get some electricity out of the deal...
Franz Jones nah but Ul get friction a fair amount of friction from the parts moving. Like space doesn’t really change that.
@@mathew66 ⭐ it's not all about the friction... Gyroscopes are already used to STABILIZE SPACECRAFT, so applying magnets and coils to the gyroscope would generate energy AND stabilize the space craft... 🤗
@@franzjones179 what
that is brilliant. absolutely brilliant.
There is an actual photo of this guy in front of blue screen while he's supposed to be on board the ISS. The gyroscope is on a string. You see it at 0:32. Notice how he doesn't allow the microphone to float.
Also important for space telescopes from what I understand
It’s like it locks its rotation to the earth’s magnetic field whenever it’s spinning! :)
Hi there, thank you for the great video. I have a question regarding the behaviour of this gyroscope during the duration of a full orbit. Will it's axis stay in the same orientation to the z axis of the ISS or will it make a full revolution during the time of a full orbit?
Cheers :-)
Thank you very much for your question Renato, this is what our experts have to say:
"The ISS revolves around the Earth on a fixed orbit and pitches to keep its nadir pointing aligned with the local zenith from the Earth surface (i.e. “looks always down”). Once setting the little gyroscope in motion, its rotation axis is fixed in space, while the ISS capsule will turn around it to return to its original orientation in one full revolution about the Earth. If one strapped up by the wall of the ISS she/he would see the gyroscope turn, but the gyroscope has fixed attitude in space (by angular momentum conservation) while the ISS has not, hence it is the ISS that is turning."
"Attitude control on the ISS is provided by four control moment gyroscopes, located in the Unity module, hosting 100kg wheels spinning at 6600 revolutions per minute, resulting in an angular momentum of 4742.5N*m*s. The wheels are adjusted in a special “pyramid” configuration to provide the four degrees per minute torque that keep the “keel” of the ISS pointing downwards as explained above (the ISS hosts a myriad of antennas and instruments and this is the best scientific and technical solution, not to mention its outreach potential, see e.g. the cupola windows). The mounting allows to generate extra torques too, i.e. equal and opposite to those generated by atmospheric drag, gravity, docking and undocking shocks and orbit boosts. Gyroscopes have limitations of course and the momentum of inertia of the ISS is a huge burden to govern, hence assistance is provided by the Russian control thrusters on the Progress and Zvezda modules. Attitude control changes and full management of the ISS bearing are simulated up to a year in advance following orbital prediction and mission design. Fair enough, the orbit of the ISS is fixed at inclination 51.64deg and 90min period, but the Earth rotates, always offering a changing face to the ISS with different local gravitational features: again the ISS orientation at every period might differ by up to a few degrees and the apparent position of the mini-gyroscope might differ across orbits."
Thank you very much for your comprehensive answer.
@@EuropeanSpaceAgency is it therefore correct to say that the gyroscope is in an inertial frame but the ISS is not?
@@JosephTosey I'm no expert, but I think that would be correct.
So how do artificial horizons on airplanes work as they turn the curve of the globe? No existing models have internal equipment to reorient the gyroscope as they turn the curve.
very interesting while demonstrating
Coolest fg video I've seen in a LOOONG time.
Very good idea and you please explain it more and more in short video.
John Theux sent me here. Big respects to him.
I'm curious, as the spacecraft orbits the earth, how does the gyroscope rotation axis change?
If the spacecraft is rotating with the same side always facing the earth, will we see the gyroscope rotating relative to the inside of the spacecraft?
Thank you, Mr. Tim Peake, this was very cool to see.
I was wondering this too. And if we ever built one of those centrifugal space stations, would the gyroscopic effect mean it was always twisting relative to the earth's surface?
Gyroscopes, when spun long and fast enough, can be seen "moving" 15 degrees per hour as the earth rotates; in actuality they are retaining their axis of rotation but it gives the appearance of movement.
Would it stay spinning forever ?
no, there is no infinite energy anywhere in the universe.
Beautiful
excellent .... finally...
Thanks.. very educative...
I must be a big kid , because I'm 52 and still think that's cool
you should attach the gyroscope to the microphone, you could go hands free 🤣
Is it possible to see bomb explosions over areas of conflict from ISS?
+Kirill Holstov I'd imagine they could, depending on the size of the detonation. I doubt most conventional bombs would be large enough to appear, but something like the Tsar Bomba probably would. But at the same time, the actual explosion doesn't linger for more than a few seconds generally. They'd have to have a camera pointing at the exact site of the detonation to have a chance of seeing it.
+Kirill Holstov Actually I take that back. Apparently there's some pictures from Gaza showing explosions from rocket attacks there. So theoretically if you were looking you would likely be able to see them. Depending on the size of course.
+BinaryHelix it would be very interesting to ask astronauts whether they can see appearing and disappearing flashes or even 3D mini-mushrooms during combats, though, of course, I wish there were no wars on our planet.
+Kirill Holstov Mushrooms? Nah if a bomb that big get's used everyone would know.
+Homer Simpson sorry, I meant dust cloud formations because of artillery strikes
I wonder if this is why there are a *_lot_* of science fiction space traveling ships that contain what's technically a gyroscope (methods, theory and techniques vary)
I have propulsion systems that utilize gyroscopic thrust.
If everything is stable in a system, and you create resistance, then you have an opposing force that would act upon the input or loss. I.e. thrust, propulsion.
it’s physics editor mode
Good to see the Union flag the right way up.
+Massimo O'Kissed Well they are in space so they is no wrong way to put it XD
@Eric Williams, it's technically only the Union Jack when flown aboard a sailing ship.
I really want to see a bey launch in 0 gravity
This brings me an idea
Just low earth orbit they are still within earth’s atmosphere. Not space 🤦🏾♂️
not actual space but the point is that it mimics space having no gravity
Headset microphones.
Would like to see if procession occurs and a flip if given time.
Wow it's very amazing
wow ..
That's just wow ..
gyro in space, magnets to turn gyros to make elektrisity better?
Will it spin forever as long as no one touches it?
whoa! so if you connect three gyros togheter (arranged on the x, y, z axes), will they be stable in 3D space however you knock them?!
As long as you can pull the giant string, id agree with you
+Francesco Di Mauro
Three gyros could be translated just as easily as one. With one gyros there is still one axes left, which is can easily be rotated around. This is no the case with two. But three will not give you any additional stability.
What about the elastic collision of two spinning gyros (with a moderate speed)? Is anything unusual?
Can you please explain why did you store the microphone instead of letting it float in front of you?
Because it would fly away. When you release the microphone some tiny amount of force will act upon it even if you try your best.
Very cool
So if you were to make a perfect gyro, and eliminate all resistance of the axis perhaps with magnetic axis points will it spin indefinitely?
maybe :)
iinRez you could just put anything outside the station, give it a spin and it would spin for quite a long time.
Magnetic resistance would slow it down.
Engineers are amazing
Let's get some beyblades into space!
I've always wondered
thats awesome
Nice!
Flerfs nightmare. LOL
Wonder how they explain this one
Cool
Hey nice stuff. But for example, does that mean that the cinema stabilised remote heads work better in space/zero gravity?
So does this prove that spin=gravity?? Like the earth, it spins keeping it's rotation stable.
The magnitude of the force of gravity is determined by the mass of each object and the distance between the centers of the two objects.
No, the fact that the Earth spins is just a "drop in the bucket" compared to Earth's gravity. All that does is make the gravity slightly less. By about a pound for a typical person, when comparing the equator to the poles.
Noto che il cerchio attorno alla ruota giroscopica inizia a ruotare pure lui, nel senso della ruota mi sembra vedere ma non si capisce bene, credo di sì: per leggero inevitabile atrito del punto di contatto comune.
“Remain in the same plane”
always wondered how gyros work in 0 gravity
Centrifugal force. The gyro is not operating properly though, as the mounts being to spin too when he let's go when on earth they would be stationary. I guess from the friction from the bearing. But the centrifugel force is still there once it's spinning, regardless of 0 G
Agree. He made it seem like this demonstration of a gyroscope was markedly different from what one would observe on Earth, but it was not. In fact were you to ride on the vomit comet aircraft with the same gyro the result would be identical during the simulated freefall segment(s) of the flight.
The centrifugal force does not enter the picture in any way Ashton Michael
wow!!
How long would it spin for in space using magnetic levitation designed gyro
gyroscopic backpack for astronaut..soon..
So what about space jet packs with gyroscopes
I don't really understand the phenomenon, someone has an explanation? a link? this is a kind of precession? (sorry for my bad english)
+Florian the spinning causes the force to be evened/averaged out across the gyro
+Florian bfy.tw/4roJ
Top link ;) which if your feeling lucky doesn't work, well done, good job google xD
Such gyros on aircraft systems like the altitude indicator, if the plane maintains the same attitude with the gyros, won't the airacft gain more altitude overtime as the Earth's surface is curving away due to the spherical shape of the Earth?
Now lets build our own UFO... 🔥🔥🔥
That is smart
What happens if you put two gyroscopes near each other?
Will they be attracted to the other gyroscope
Or what if you had a gyroscope in a hollow orb and put water on the outside does the rotational movement affect the water?
FUN!
it will spin forewa
Gyroscopes are already like witchcraft down here on earth. So playing with one in ~zero gravity must be nuts.

@@beckydoesit9331 Yes, he is an actor hired by the alien lizards that live under the Pyramids of Egypt. The world's greatest minds have been tricked into believing science, but not you. Despite doing poorly in school, you have seen through a conspiracy that has eluded literally millions of the world's brightest people. Well done - you are very special.
It did actually change its plane when he knocked it. I would’ve liked a demonstration were he held it in both hands and changed its axis. This would’ve shown the effect it had on his axis. If you sit on a swivel chair and hold a spinning bicycle wheel. You can get the chair to spin around by tilting the wheel. This is NASA! I would’ve expected more.
Soo cool
Wheat happens to the string?????
Hi
Great
awesome video :) (y)
Idol❤️
Conservation of angular momentum
is this a good example of rigidity in space? I want to use it in my CFII lesson plane slides
问题来了。现在的环境是什么。地球低重力？地球与月亮间的无重力。还是月球环境。他与什么平行？地球? 如果他一直保持这种飞行姿态。靠近月球或者火星。也许是头朝下的哦。我记得俄罗斯做个一个实验。一个T字型的螺丝扳手。旋转的时候会出现反转。这种误差 在 我们去火星的时候会不会是致命的
So does it assist in turning?
This video needs HD and slow motion. Included should be the number of revolutions along the length axis ratio to the same 180 degree rotation of the matter along the intermediate axis. More T-shapes should be tested with different proportion ratios. Do different initial spin directions result in an opposite intermediate arc directions as referenced from the video angle?
Rotation direction will change the Precession direction. But if the top is symmetric, like the one in this video mostly is, then changing direction has no effect, it would be like looking at it from the top down or bottom up.
Hitting each end is like hitting the same end while spinning the other way.
Lots of TH-cam Videos about precession.
Not sure what the first part is, (The first part in your comment).
Guessing T shape is the type of mass distribution for the gyro. If this is close to what you were suggesting, I think you may like this video;
th-cam.com/video/ZwBg4d7Wx1s/w-d-xo.html
Is this the same principal that is at work with the planet earth, does the planet maintain it's axis as a result of the force exerted by the spin of the planet? And ... if so, why does the planet "wobble" about that axis, instead of a being steady at the axis?
Because unlike the gyroscope, our earth isn't perfectly balanced on the outside... we got mountians an landmasses, all unevenly distributed that contribue to the wobble.
@@Cliffmchrist Thank you.
@@Cliffmchrist That doesn't adequately explain it. The Earth precesses, that means it follows a pattern of revolution around its untethered axis. A precession requires a sustained torque. If it were the unbalanced nature of Earth causing the wobble, it would tumble and eventually fly off like an unbalanced tire. This is a question that hasn't yet been adequately answered by astrophysicists.
So is that how the Earth hold this angle of tilt?
Yes. As far as your lifetime is concerned, the Earth's axis of rotation will point toward Polaris (approximately). It points to a fixed direction in space and the axis of Earth do-si-dos around the sun.
There is a very slow change in the axis of rotation due to tidal interaction with the sun and moon. This causes the axis to wobble, over a 26,000 year cycle. In the time of Ancient Egypt, the north star was another star that we call Thuban today. And in another couple millennia, there will be another north star still.
Scale this mechanism up to where is the center mass of a large spherical habitat where people live in the atmosphere between the inner and outer shells of the sphere. In other words use a scaled up gyro like the internal moving core within the earth.
Oh I’ve heard about that movie!
Hey vsauce!
Reminds me of how a UFO behaves
crazy
Is there a big gyro on the station?
There are quite a few actually! :) they are called the control moment gyroscopes. I think there are 2 active ones and a back up?
Why is the other gimbal ring also rotating?
Why not?
It is correctional.
Friction.
You are just one tiny step from using it for propulsion.
interesting, i am amused
Done, thumbsak
Your finger glitched bud 😎
if you make an gyroscopic engine with sufficient mass could it be used as a propulsion device used to move or stabilize a larger structure?
They actually use several sets of gyro scopes to steer space based telescopes since rockets would cloud the optics with exhaust.
Ground control to Major Tim... Lol. had to. On of our greatest living sons! (British)
will it keep spinning forever? YES OR NO
thank you Shawnaldo75
if there's no internal friction (and is in space) it should.
