Gyroscopes in space

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.

[@whoeveriam0iam14222]

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

[@__Paprika]

that's an interesting question, i'd think that too

[@__Paprika]

***** 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.

[@whoeveriam0iam14222]

***** 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?

[@__Paprika]

***** ... 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.

[@__Paprika]

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

Where does the gyroacopes sit on the station?

[@RenatoVK4TNT]

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 :-)

[@EuropeanSpaceAgency]

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."

[@liljuulmane5379]

saaaaaaaaammme

[@franzjones179]

@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...

[@seanmashley9228]

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.

[@Pablosammy1]

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?

[@jackbalmy1392]

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.

[@informer3000]

Beautiful

[@iinRez]

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?

[@martinvargas236]

maybe :)

Is it possible to see bomb explosions over areas of conflict from ISS?

[@BinaryHe1ix]

+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.

[@BinaryHe1ix]

+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.

[@95t95t95t]

+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.

[@robh467]

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.

[@dontlookspins]

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.

[@carultch]

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.

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?

[@Cliffmchrist]

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.

[@gadjetramjet]

@@Cliffmchrist Thank you.

[@marcv2648]

​@@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.

[@masonjustice7303]

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?

[@brycering5989]

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 KZbin 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; kzbin.info/www/bejne/kKilmGeabLyrZ9U

[@rockymoney7742]

So is that how the Earth hold this angle of tilt?

[@carultch]

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.

[@solarion9802]

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.
