Sounds like bullshit to me. Why would a crack, catastrophic or otherwise, cause a deorbit. Orbital mechanics don't work like that.

The wall of the ISS is pretty thin aluminum, and it's been up there a long time, I guess some kind of cyclic fatigue from heating and cooling could be causing problems. The micro-vibrations sounds like voodoo magic to me.

If it caused a pressure blow out, then material ejected from the station could cause a loss of control of the station. Loss of systems from the blow out are part of the considerations.

As for causes, everything vibrates constantly. Usually they are imperceptible or unimportant for consideration since the structural systems you see on Earth are generally robust enough to handle the design loads.

Some structures on Earth have specific dynamic considerations that account for fatigue (cranes, machine floors, sky scrapers, bridges, etc.) but what sets terrestrial structures apart, is that we still have the ground we are tied to which presents a place for loading to go (or come from).

In space there is no rigid boundary point for us to tie to, so the dynamics of an orbital structure are going to get weird when compared to those on Earth.

Generally boundary conditions simplify mathematical systems in structural analysis, so lacking those means more complicated design equations and a greater chance of error.

Additionally our understanding of material behavior under load (stress and strain), has improved significantly over the past 20 years, so older designs were generally conservative, however there have been instances were design methodology was found severely lacking, opening up opportunity for failure that was never considered in the past.

Finally aluminum is a strange metal to work with, so that could be an additional failure mode, it has ductility, but at comparatively higher temperatures its ductility is reduced. This could cause thermal stress issues, particularly if near dissimilar materials.

TL;DR - Structures in space made of glued together beer cans will flex like a strip of rubber.

Really though, you'd think any momentum caused from ejected mass/vented atmosphere could be countered by the numerous thrusters.

station keeping would require it to be able to adjust its position from time to time anyway, all orbits become unstable over x amount of time, the thing was always going to come down.

the problem is when bits and pieces start failing it im thinking it wouldnt be able to keep itself stable as well.

im gonna go with actually feasible. i dont know how high above atmospheric friction that could seriously affect it it is but if it is in a portion that does experience drag then yeah without station keeping its going to slow down enough to deorbit.

NASA: Muh ISS is made of thin aluminum.

Also NASA: 100 tons of space dust and small meteoroids, also known as micrometeoroids, enter Earth's atmosphere every day.

Any one of which is capable of catastrophic damage to ISS.

Relax guy, I never actually claimed it did, however since 9whatever they claim) the ISS is in low Earth orbit, i was alluding to the 'fake and gayness' of manned flight in deep space.

Station was fucked thanks to that one insane woman. The whole ISS smells like shit and the US toilet is busted. She may have drilled holes in various places that later caused catastrophic failures.

They intend to sell it off/rent it to private interests starting in 2028 so that companies can test future habitat platforms. Deorbit after 2031.

[ - ] dassar 2 points 6 monthsDec 17, 2024 19:45:57 ago (+2/-0)

Yea, there is an older NASA white paper on addressing the aging out of the 2 Russian components - 'Functional Cargo Block (known by its Russian acronym as FGB) and the Service Module (SM), two of the early modules on the Russian Segment, would reach the end of their certified lives in 2013 and 2015 respectively'.

The ISS was originally certified to 2016, they wanted to extend this service life to 2024 and then 2028 for private interests.

The thing is at junk stage. even before that retarded woman drilled a hole in it and spread fecal particulate throughout the american part.

Oh, right! I remember that now. The total collapse in competence of multicultural society led the US to still not have a launch vehicle 15 years after the Shuttle’s retirement, so they had to push back the lifespan of everything else ever since in order to save face. I don’t think we even have a plan for a new space station yet.

AI Overview
The International Space Station (ISS) is experiencing a leak that has raised safety concerns for astronauts and the station's long-term viability:

Leak
The ISS has been leaking air since 2019, and the leak has worsened over time. NASA and Russia's Roscosmos space agency disagree on the cause and severity of the leak.

Root cause
Russian experts believe the leak is caused by micro-vibrations from mechanical systems, which can lead to "high cycle fatigue". NASA believes the leak is caused by multiple factors, including mechanical stress, environmental exposure, and material properties.

Catastrophic failure
NASA is concerned that the leak could lead to a catastrophic failure of the ISS, which could mean its destruction. Russian officials believe the ISS is safe and that the idea of a catastrophic failure is an exaggeration.

Agreement
NASA and Roscosmos agree that the problematic segment of the ISS may need to be permanently closed if the leak rate becomes "untenable". However, they disagree on how to define "untenable".

Sounds like the AI could be talking about a crack, since the hole(s) we've heard about would not lead to a "catastrophic failure of the ISS". Same with a leak rate. It would only increase with a crack or deteriorating materials, not a simple hole.

I wonder if this is at least partially related to the dyke who sabotaged some modules so she’d be sent home sooner.

[ - ] Bassman9000 3 points 6 monthsDec 17, 2024 16:57:45 ago (+3/-0)

From some sketchy write ups about that bitch's actions. It seems she made the ISS basically unlivable. The smell of feces and rotten food is stuck in the entire apparatus.

The hole she made forced the hull to crack. This entire experiment on behalf of humanity was ruined by one dumb cunt.

[ - ] Sector2 2 points 6 monthsDec 17, 2024 16:54:06 ago (+2/-0)

Wasn't that around the time they said she drilled a hole in the hull? If that were true though, a hole would be easy to plug. Being related seems probable.

[ - ] the_old_ones 1 point 6 monthsDec 17, 2024 18:06:41 ago (+1/-0)

a hole would be easy to plug

plugs break, the patch can't possibly match the original material. i would not be shocked if that hole she drilled just kept growing into the big crack that supposedly exists now

[ - ] dassar 2 points 6 monthsDec 17, 2024 19:52:14 ago (+2/-0)

Yeah, a simple hole can completely fck structural integrity of something designed to be pressurized and airtight, totally possible/ probable to result in microscopic hairline stress-fractures in component parts.

JAL flight 123 is a pretty good analogy -

https://en.wikipedia.org/wiki/Japan_Air_Lines_Flight_123

bad repair work on a rear bulkhead after a tailstrike + thousands of compression/decompression events + dud patchwork repair instead of replacement blew out the arse end of the plane.

investigators worked it out because since the original repair theyd found nicotine stains or some shit like that coming out of patches from previous repair work on the wrong side of the bulkhead, then found massive fucking cracks all over the bulkhead underneath the patches.

wind paperclips backwards and forwards they get real hot and just snap eventually, same thing.

If true, theyll just have the SSP taxi them out.

The crack could have been caused by spaceniggers, calculating the scenario that the U.S. would most likely use its own secret spacecraft, opening-up space and beyond, to the news cycle, and a big canoworms about suppressed tech (which the aliens had first, so theyre the actual first suppressors).

Because the spaceniggers and caveniggers sure as shit aint gonna do it until Trump is in fresh, they just can't, they need "the occasion" you see

the specific one actually. the woman astronaut who went nuts, drilled a hole, spewed shit and radiation throughout the station, and then they blamed that hole on the russians

Interesting - the fact of the matter here is something about which they cannot lie because every orbiting object is tracked, right down to tiny pieces of debris.

I'll check through some previous ISS orbital elements tomorrow, and I'll be saving snapshots of them now. They're publicly available here with ISS at the top.

I have my own tracker for those, but they'll be compatible with free software such as Gpredict.

You mean if something is pressurized and began to leak air, that wouldn't result in loss of ability to maintain orbit.

EDIT: I dont really care about this normie fear porn, but it is constantly losing altitude every week/ month regardless of a crack.
Until propelled back up by a propulsion module or shuttle.

You mean if something is pressurized and began to leak air, that wouldn't result in loss of ability to maintain orbit.

i think it would lose its ability to maintain its orientation easily, or support life if it leaked air, and even a little bit over a very long time will push it in the direction away. if there was an explosive decompression that would give it a knock in an orientation in a... ill say 'non optimal' direction depending on how much came out how quick. remember that all engines used up there get rated pretty much by 'specific thrust' so tiny amounts over a long time can do the same as a lot over a tny amount of time.

its drag thats going to be the problem, if its close enough to something that can slow it down, then its in trouble because it will deorbit then burn up in the atmosphere like anything else, and if theres extra solar activity at the wrong time in the iss' orbit that can create friction in itself.
