Graveyard Orbits Where Old Satellites Are Forgotten 

Hmmmm that's very interesting and very problematic. I feel like laws about geostationary orbit should be updated to deincentivize this behavior.

Nathanael Vetters laws? we're talking about international competition here. It's very difficult to regulate beyond "if we don't at least do this we're going to all lose money". Something like this being problematic isn't going to get China or Russia to play ball because they'll just see it as a power play by the country that proposes any new regulation.

@@notsogreatsword1607 you've just watched an entire video about international law and you still think markets can't be regulated ?

There are laws indeed regulating the use of geostationary orbits that define the size of slots and to what countries those slots are assigned to. As per those laws, there is a limit on how much time a country can keep its slots unoccupied, and once that period expires other countries gain the right to use that slot. This is the reason for placeholder satellites; since not all countries can immediately replace satellites that have reached their end of life, they may "buy additional time" by parking a satellite that is no longer useful but still controllable in their assigned slots until the useful replacement is available.

@@booketoiles1600 the sheer number of war criminals who are not prosecuted is proof that "international law" has no teeth.

Sounds like a weapon upgrade in the Fallout series

Already been done. Andy Griffith, Joel Higgins, Salvage 1, 1979. Built his rocket ship out of a cement mixer to recover space debris.

by the time we can easily retrieve them, those things will be antiques. lol

In addition to the movie described by John Rielley, there's also an Anime with that plot, "Planetes".

@@johnrielley7756 I loved that show. I remember they developed that magic rocket fuel called "monohydrazine" which had huge specific impulse and allowed all the single stage to orbit adventures on the show.

Same here.

I like to see a sat. in orbit . that ESA vid is not showing the real deal.

@@itsmenoname2247 True, as the object melts, it's aerodynamic properties would change, causing it to roll and spin, changing the leading edges and eventually breaking into smaller chunks. This would be difficult to do in a test setting.

You never played with a blowtorch as a "kid"?

True but a satellite might be a few hundred kilos or less of useful metals. One asteroid could be millions of tons.

How much fuel would you need to expend to rendezvous with each one?

Calm down canook

Much much lol

I'd never seen a proper explanation.

@@absalomdraconis So, you'd like an inclination perturbation complication explanation recapitulation? Fred

More like grapeshot.

Only way I can think of to make it worse is "more" and "on fire".

For that you need AcK/NaK protocol.

Wouldn't it be preferable to have your ashes spread all arould the planet Earth from a Low Earth Orbit? And it's realisticaly affordable(~$8000), to lauch a ash urn the size of a cubesat.

No need of that, Billy ! 2007 I had out of body short space travel. My soul went into orbit, got few circles round the Earth and for my great disappointment I got back in my heavy, slow body.

@@rachelslur8729 but then it just comes back. I want mine on a rideshare with something going to deep space.

Yeah, but in time, won't the orbit decay and then it will be a problem? Seems like we're got a big future problem.

@@russellhltn1396 Our species has many big future problems.

@@russellhltn1396 LEOs decay because of atmospheric drag. That isn't an issue out there. As for tidal forces, I've read that they bring slightly-below geostationary orbits down and actually RAISE ones above (same principle as in flyby maneuvers, I understand, and the mechanism that keeps the moon moving away from us!) If correct, that may be another or even the primary reason for putting all the graveyard orbits above the active ones!

Rapid unscheduled disassemblies?

@@georgf9279 There is a phenom that happens with high pressure and flow velocities in rocket nozzles that can make the flow non-uniform and potentially destructive. Think about hitting the natural frequency of an object but that object is the exhaust of an engine...assuming I understand the concept. So eventually yes an RUD could occur LoL

I tried to scavenge all what is available on Internet first, on university textbooks second. Not much is available, really. A couple of fluidodynamics equations, where observational parameters outnumber the system variables. In the end, you write your simulation software based on injectors, pressures, shape of chamber, and move from there. All because few atoms of oxygen can move a large flame front from one side to another.

It looks tighter than it really is due to the display being two-dimensional. If we could see it in 3D it would look more dispersed.

If you're replying to Starlink, I assume it's because they're not geostationary. They cover the entire earth with a grid of satellites, so geostationary orbit isn't necessary (which is used so that one satellite can cover a region continuously). If you look at 08:37 you can see that they move across the earth's surface, and are therefore not geostationary

It was in 1978, quite a while ago (before the internet and YT...)

@@gordonrichardson2972 And me apparently. :P The internet was around back then. It just wasn't available to the general public since it was still under DARPA at the time if I'm remembering things correctly. Still interesting to know.

I think they had one of two liquid metal reactors connected to the grid in France, but I'm not sure if they were NaK units.

I think the NaK was just coolant for a uranium core.

The Russians had a great love for sodium cooled reactors. And many deaths as a result.

Dr Vidya I think the overall tracking is done by NORAD, possibly with a similar facility in Russia. Not sure how much active work is done by the people responsible for dead satellites, as there's probably nothing they can do without fuel and communications.

Dead satellites and space debris is only monitored and tracked - not much can be done as no one can control them in any way. Active satellites are managed by their respective owners: governments, private companies, public institutions, schools, private foundations and in principle even individuals. Amazon even offers satellite tracking and management as a service: aws.amazon.com/ground-station/

It wouldn't be to hard to make a spacecraft to go there right now, except there's no way to grab an unpowered, possibly tumbling satellite. If you can design a system to capture satelites without making more space junk, then putting an ion thruster and a big tank of xenon or krypton on a basic bus with a solar array is fairly straightforward.

"super efficient" "landfill" wat

I am more interested in using them as a material feedstock for orbital industry.

Not until we have a serious infrastructure established in space, including propellant manufacture.

If we get a large space industry someday and have efficient enough engines, it might be profitable someday to collect and recycle old spacecraft. It would depend on the size and composition, of course, I'm guessing that larger satellites or ones containing rare metals would be the first to go. I could see, maybe in one or two hundred years people using ships to collect satellites from graveyard geostationary orbits since the fuel to go from one to another would be pretty small since they'd be in very similar orbits.

@@MoraFermi Sure, that must be a given, but besides that. Like will the radiation be a problem etc.

By that time I suspect most of the satellites will be considered artefacts or relics from a bygone age.

Plus raw materials from the asteroid belt / the moon might be much cheaper and more available. There might be some collectors who like putting old spacecraft in orbital museums though, that'd be cool.

So. Got a hot cadaver to unload, eh? Fred

Thumb down is a new "first" apparently.

Good catch, the diagram is indeed of the Earth/Sun Lagrange points. Of course an Earth/Moon diagram would look exactly the same just with Earth at the center.

They need active attitude control generally.

I think this is called gravity-gradient stabilization. Do they design geostationary satellites to gravity-gradient stabilize themselves in order to point their antennas at Earth with minimal need for thruster application? I would think so, to some extent. Do they also use momentum wheels? I'd imagine they use everything that can be thought of that is most efficient and reliable. Thrusters, momentum wheels, gimbaled gyros, solar sails, gravity-gradient, magnetic coils, magnets and tethers. Whatever gets the job done balancing cost and reliability.
