How We Take Spacecraft Out of Orbit

[@StarTalk]

What did you learn from this Explainer?

[@homerodysseus4203]

That the ISS isn't going to be tearing into some unfortunate poor peoples' houses when we retire it. China on the other hand....

[@benjamindemontgomery6317]

Why don't they recycle the space station when we build the next one? ready available materials.

[@ChristopherCurtis]

6:00 headwinds in the troposphere are insane!

[@ShonMardani]

Only racist and fakers call their competition an adversary.

[@ChristopherCurtis]

Neil mentioned that the materials and technology are much improved. @@benjamindemontgomery6317 It may be worthwhile to reuse the solar panels though. It's certainly not practical to try to bring the raw material back safely (remember, there's no ablative layer on it now) and try to scavenge what's left from the equivalent of a 1989 space Buick.

[@peakingmantis5331]

When Chuck said 42, I felt that.

[@CineSoar]

As someone who hated rote memorization, the multiplication table is 'fuzzy' around the mid 6's and 7's. So, I actually came to the correct answer at about the same moment Chuck did. I do think he missed a comedic opportunity to echo Neil's frustration, when Neil says "49 is twice 25."

Always great to see Neil using his office, at the Hayden Planitarium as a set . So many interesting books and artifacts just out of focus. Would be great if when filming from his office that Neil shares some info on the books on his shelves. Ideally, one title every time he post a video from his office, but even a Book of the Month would be great. Books are awesome, they don't need batteries and totally impervious to solar storms and any other forms of electromagnetic interference. Please share !👍👍👍

Don't know about Chuck and Neil, but I think most of us learn "two and two make four" even before we learn that E = mc^2. Fight me on this one.

[@mikeuk666]

😂 yes

[@vanshamb]

I learnt KE = 1/2 MV² much before E=MC² Idk why Neil didn't use kinetic energy to explain it, am i wrong thinking this way?

[@yessopie]

@@vanshamb If you actually study physics, you learn that K=1/2 mv² much earlier, but people who haven't studied physics have never heard of K=1/2 mv², they've only heard of E=mc², even if they never really understand what it means. Abstractly, though, both equations say the same thing about energy: that it has _dimensions_ of mass times velocity squared.

[@y4playiny4self]

@@yessopie Isnt K=1/2 mv`2 a tiny part of the full E=MC`2 equation?

[@petersage5157]

@@vanshamb ur not wrong; I think Neil was just going for the low hanging fruit that the common undereducated American would know, even if their understanding of it is closer to E = MC Hammer. The kinetic energy formula is precisely what engineers use for spacecraft kinetics. The kinetic energy formula is part of General Relativity, and in non-relativistic cases GR reduces to KE. The mass energy equivalency is what Special Relativity reduces to for speeds that are not a significant fraction of the speed of light. They're both parabolic equations that fall out of hyperbolic equations.

[@CMDRGhostNappa]

@StarTalk , im glad and appreciative of Chuck touching upon a subject that almost no one talks about. I understand this is the primary channel , but I do believe having a podcast about mental health in general would be a great subject for your secondary channel Startalk +. It's not everyday that astrophysicists come out and openly talk about their mental health. Chuck I appreciate you.

[@a24396]

This video is why I don't do math in public... And kinda' not cool to both put Chuck on the spot like that and then shame him rather than just say something like "Not quite, I think it's 49" (or something similar) Lastly, Chuck, thanks for being so willing to share your struggle with depression - that's a very difficult thing to talk about, and, as you said: often a source of shame. I'm glad you found the help you needed and what worked for you!

[@stevenqirkle]

I disagree. Unless you have a severe learning disability, I think it’s kind of shameful to not know your multiplication tables as an adult. I agree it’s not cool to shame people with disabilities, but in Chuck’s case I suspect it’s probably not a disability, but rather he just didn’t do his math homework in 3rd grade.

[@a24396]

@@stevenqirkle I don't agree. Not everyone can recite multiplication tables for a variety of reasons, many having nothing to do with severe disability. Just like some people have bad spelling. That's not a moral failing either, however much you may want to judge people for that.

[@stevenqirkle]

@@a24396 in a 10x10 multiplication table, there are 55 unique combinations to remember. Anyone can do it. It’s nowhere near as difficult as spelling, which has a much larger vocabulary as well as many homophones and irregularities. What other reasons are there besides not putting in the effort and/or learning disability?

[@a24396]

@@stevenqirkle Incredulity is not an argument. Just because you can't imagine this doesn't mean it's not a real problem for people who are both not lazy and not profoundly disabled. I recommend you go to google and search for 'reasons people don't remember multiplication tables.' You might discover that human brains aren't just biological equivalents of calculators/computers and not everyone is 'wired' the same. In the same way that some people 'get' spelling and others don't, some people 'get' mathematics and others don't. Or... Continue to disbelieve anything you don't understand or for which you haven't figured out an answer... Whatever makes you happy!

A helpful analogy for visualizing an object entering Earth's atmosphere is to envision yourself in a speeding boat, seated at the edge, with your hands skimming the water. The sensation of the turbulent fluid rushing past your hands, potentially causing harm, mirrors the experience of an object encountering Earth's atmosphere.

Seems very wasteful to just deorbit the ISS. Why can't we just add it as a "back porch" or something to the new station like they did in Valerian and the City of a Thousand Planets? At least have it to use as spare/parts/metals we can reuse without having to launch more material/parts again.

[@christophercurtis2817]

Why would we not try to send the Space Station to another orbit away from us we could use in the future?

[@KlestoHeHe]

the reason this wont work is because of the space station doesnt have a mean of propulsion or something to move (Besides RCS). Also putting force on the space station can also have stress on the solar panels which would make them break off.

Actually, about the Chinese station: they wheren't invited because the US was convinced they would steal tech. The other countries actually wanted to invite them to the station. Because the US said no, it didn't happen.

[@kc2213]

The Americans are sore losers. China now has their own modern space station while the ISS will be obsolete in the next few years. When the Americans can't compete, they will resort to sabotaging and kneecapping their competition. It seems like they haven't learnt from banning China from the ISS. Case in point, banning China access from high end chips will do nothing but force the Chinese to develop their own chip manufacturing technologies. The idea that the Americans think they can technologically hold back a nation of 1.4 billion people that graduates hundreds of thousands of S.T.E.M graduates annually is absolutely LAUGHABLE. Not to mention, China is a nation with literally thousands of years of history.
