That "honeycomb" shield is such a cool idea, and a beautiful illustration of Newton's 3rd law. Like... no, we can't just *stop* the projectile; but there's no reason we can't cleverly (and destructively -- but strategically so, akin to crumple zones on modern car bumpers) redirect its energy back on itself and away from the goods!

[@ExtantFrodo2]

...or like in some martial arts... using the opponent's energy against them. It is in truth not an impenetrable barrier, but a true deflector. Now imagine some material as a rapidly spinning -disk- *CONE.* What then?

[@resurgam_b7]

​@@ExtantFrodo2 There is no way you could spin the cone fast enough to matter. Even if you could spin up your shield to 100,000 RPM (approaching the limits of feasibility for current material science), from the projectile's point of view, it would still be basically stationary. So the impact would be very similar to what was demonstrated with the angled plate. You would also need a double layer of spinners, and whatever mechanism is doing the spinning since the protected area of each one would be a circle, you'd need the second layer to cover the gaps in the first. That is to say nothing of the added complexity and weight of such a system. If you could some how spin up a cone of material to the required speed, that would make for some very interesting interactions. I suspect that the cone would become more effective than an unmoving plate since the spinning would be bringing more material into the path of the projectile than a stationary plate of the same thickness would, effectively making the spinning plate thicker. That's just a guess though; hyper velocity impacts are frequently unintuitive and behave very differently than "normal" impacts so I doubt that we will ever see this particular thought experiment demonstrated outside of computer simulations, if even in that.

[@3c3k]

That is not Newton's third law. Newton's third law will only say the same force will be applied to the asteroid as the shield(because of which it evaporates)

[@ExtantFrodo2]

@@resurgam_b7 You offer some good thoughts on this matter. In addition the spinning center of the cone would be as ineffective as stationary material would be since it would not be presenting the same "thickening" aspect. The overlap you mentioned would have to encompass those areas as well.

[@resurgam_b7]

@@ExtantFrodo2 That's a good point, I wasn't even considering the center of the cone and the attachment point. I imagine it would be fairly catastrophic for the spacecraft if the bolt holding the ludicrously fast spinning mass were to suddenly disintegrate from an impact directly to it. Come to think of it, a hit anywhere on a shield like that would almost certainly unbalance the cone and cause it begin oscillating horribly if it didn't just break up immediately. Then you would get hyper velocity cone fragments to deal with in addition to the micro-meteors you were already facing. All in all a bad day for the astronauts I'd say!

Eastern eggs are typically intended leftovers in a production that is sufficiently large, expensive, or manned, sometimes as a joke, as a reference, as a homage, or for marketing purposes (and building up a hype). It largely depends on the audience commitment (you don't use them in a video intended for casual viewers or grandmas) and the solemnity of the product (you don't use them while explaining Holocaust). In the recent times Eastern eggs are done for the sake of it, most commonly in movies, cartoons, video games, as well as short documentaries such as this one, because it would be weird to do so in a piece of music, for example. Normally the media itself has to be multidimensional and possess a multitude of sensory streams, so anything that has a moving image is basically quite compatible with the concept.

"Meteoroid and Debris Protection" was about 2% of the Space Station's budget (I worked on that project). It has the "Whipple shields" described in the video to protect the crew modules and pressure tanks. The now Space Force tracks dead satellites and debris in low orbit, mostly with radar. If a bigger piece looks like it will come too close, the Station moves out of the way. Windows not only have covers when not being used, but have four layers of glass. Losing a window would be a catastrophic loss of pressure. Some stuff just doesn't need protection. The solar arrays have been punctured multiple times, but they are so thin stuff just flies through. There are thousands of solar cells, so losing a few to impact damage isn't a big deal.

The shields do not generally need replacing as the holes are few and far between and the damaged area is very small so it is extremely unlikely that the same part would be hit again.

@@listerdave1240 ah, that makes sense... I guess it's because I'm a programmer I tend to focus on the absurd worst cases (if you don't handle all the unlikely but possible events in programming, sooner or later one of the "unlikely" worst cases is going to happen 600 times per second on the production server.. so it's better to at least return an error early if not actually handle it); but I guess in (physical) engineering you probably can and should build things for the most likely events and not the infinitesimally unlikely ones. 😂
