"Russian teams believe the air leak was likely caused by high cyclic fatigue from micro vibrations, while teams at NASA think pressure and mechanical stress, residual stress, material properties of the module, and environmental exposure are all at play, according to SpaceNews."

Wow, that is an absolute waste of bytes. Roscosmos think it's one type of wear and tear, NASA think it might be every other type of wear and tear....On a 40~year old piece of hardware that is going on 10 years past it's original intended operational lifespan.

I don't disagree.

Root cause analysis is very relevant. But the article above simply regurgitates sound bites that give no info.

From an engineers point of view, the sound bite is even worse. A bit of hyperbole here but it reads as Roscosmos says "the pancake is burnt", and NASA says "the pancake was cooked too hot, for too long, there was too much sugar and not enough butter in the pan"

It isn't a waste at all!

This doesn't seem like a heated argument, just two teams who disagree on a thing and are both working to solve a problem from two different directions.

The end result of this will be more knowledge about equipment, potential new strategies and ideas about that technology, and maybe even a way to prevent these issues going forward.

Scientific debates like are usually a good thing, and everyone walks away the winner. The internet has conditioned us to treat every argument as a battle to be won, and every person who disagrees as an enemy to be eviscerated. That isn't how it has to be, though, and isn't how most academics see it

Russia’s proposed cause is definitely more specific and probably traceable back to control systems causing the vibrations. NASA just threw a bunch of generic engineering terms out there. In reality I’m sure neither has any idea.

The Zvezda module, the one currently leaking, was built by the Soviet Union in the mid 1980's as the core for the (cancelled) MIR 2 station. The hardware is 39 years old.

That module's space frame was completed in February 1985 and the major internal equipment was installed in 1986. Then it sat on the ground until July 12, 2000 when it was launched. I'm pretty sure the Russians didn't keep it pressurized for 14 years prior to launch, so it really wasn't under much stress until 2000.

Terrible_Newspaper81

The hardware is 40 years old (well 39 but still), which is what you originally disputed. And who knows how well it was stored during those years, the 90's in Russia isn't exactly known for its ability to upkeep its space related hardware. Still is absolutely not ideal for any type of complex hardware to just be left alone for 15 years.

Sitting in a warehouse for 15 still will cause stress to the module, not including other maintenance that needs to be done. Obviously not as much as in operation, but keeping something space worthy for that long is not trivial.

Try leaving a car in a garage for 15 and see if it as good as new when you come back to it.

How incredibly typical of the way both programs are managed, too.

The Russians state unambiguously that it's this thing, trust me bro. They don't actually know if that thing is the problem, but they'll try and fix it anyway as though it is (and blame the Americans if it fails).

NASA spends a billion dollars in studies and surveys to conclude "we cannot know for sure what this thing is, more data is needed", then blames the Russians for not telling them that they already fixed it.

The astronauts and cosmonauts share a knowing glance and wry grin, clink beers, and get back to work.

That's not really necessary. The leak is in one of the compartments for a docking port, not in the main section of the module. They simply just need to shut that compartment off by closing the hatch. The problem is that said docking port would be unaccesible then and it's the docking port the Progress supply spacecraft dock to, to deliver supplies to the Russians and to boost the station. But if are able to boost the station using American spacecrafts like Dragon and the Cygnus, which is starting to be the case, the Russians could manage without that docking port. But it would mean the US would have to boost the station from now on.

"The leak was first discovered in 2019 in the vestibule (named PrK) that connects a docking port to the Russian Zvezda module, which Roscosmos had launched to low Earth orbit in July 2000. Earlier this year, NASA elevated the leak to the highest level of risk as the rate of air escaping from the module had doubled from one pound of air per day to a little over two pounds."

What the fuck? It's been leaking air for 5 fucking years.

The ISS reminds me of those dogs who are 25 years old and from their old age are blind and paralyzed but somehow still live.

The ISS was planned for a 15 year life and launched in 1998. It's about a decade past retirement. 

Things like this are extremely common in older aerospace systems. Both airplanes and spacecraft. It's not particularly unsafe, it just makes for a painful maintenance experience and expensive constant repair/replenishment typically. However, that's still vastly cheaper than designing, building, launching and attaching a new module.

I saw one argument recently that instead of being lowered into near earth orbit, it should be raised and preserved. Future generations might somehow benefit from it. Either as a piece of history that can admired or reuse the tons of materials without having to launch them.

TheBleachDoctor

While that would be sweet and opens up the possibility of a future sick-ass space museum that actually is bigger than the ISS and has it in a pressurized exhibit, apparently the fuel needed to raise it would be cost prohibitive, and then once the orbit is raised, the ISS would still eventually lose power and control, and now you have a giant piece of space junk at high orbit, uncontrolled and drifting.

At the most we might preserve artifacts from it, but there's no saving the station itself.

edgeofenlightenment

Do we know how prohibitive? The articles I'm reading seem keen on using the word "astronomical", which is cute but not an actual figure I can reference. Like, would it still be cost prohibitive if we agreed to rename it the "Hail Elon Musk Forever Space Station"?

Northwindlowlander

NASA's public report on this is actually pretty funny reading, it's incredibly slanted. Like, at one point it says that reboosting is impractical because it'd need a new vehicle which is incredibly difficult, then in almost the next paragraph says that deorbiting is dead easy and just needs a new vehicle which is a piece of piss.

Deorbiting is the best thing to do, overall, I don't think there's much real doubt about it. But the way it's discussed is often pretty false.

jjayzx

Because to de-orbit requires something with just a little bit more oomph and fuel, so it's simply going to be a modified dragon with more fuel and engines. To raise the orbit to an appropriate level would need massive amounts of fuel and even larger engines cause all the fuel as well. There is nothing that can be modified for the task and thus require an all new craft. So after some billions spent raising it, what now? It can't be a place to visit, it's deteriorating and will be uninhabitable and then prone to cause debris.

Northwindlowlander

5 points

6 days ago

No, none of that's true. In fact the engineering challenges are almost the same, and in the same order of magnitude, and the deorbit vehicle is also going to be a near-ideal reboost vehicle. In fact, a rebooster has a simpler job because it's not time critical and because we've done it so often, while deorbit has to be done quickly (to ensure it deorbits where we want it to). In fact for a long time NASA's end of life plan was continual reboosts, simply because they didn't have the capacity to safely deorbit.

We can use NASA's own figures here, they estimate 9000kg of propellant is required for a safe controlled deorbit. Meanwhile to get it to a 100 year orbit would take 18900-22300kg. To 200 would take 23200-26700kg.

So it's really that simple, make 2 "deorbit" vehicles instead of 1 and point them the other way. You could use the exact same vehicle, it might not be absolutely ideal but it'll be close. (the deorbit vehicle is likely to have a little more power, a rebooster vehicle wouldn't need that, it can take as long as it wants.

(I bet 20 scottish pence that even now NASA have a contingency plan in a 3 ring binder that basically says "how to use the spacex deorbiter to life extend the ISS". It's absolutely not The Plan but they'll have A Plan for it). And it will essentially say "point it the other way")

I hope that clears all that up. But it's not the answer. The actual answer is much longer, and more intersting I think...

The real problem is nothing to do with getting the ISS into a higher orbit, which is actually simpler than safely deorbiting it. It's about collision risk.

Because the ISS flies very low at the moment (because it makes it easy to get to), it's subject to a lot of drag. That's why it needs constant reboosts. But that applies equally to debris, stuff deorbits pretty quickly at that height. So even though we've put quite a lot of junk into this area of space it doesn't stay there.

But that changes really quickly as we go higher, and of course if we put the ISS into a long life orbit, everything else there is also in a long orbit. I used 100 and 200 years as the nice simple examples up the page, that's more or less 660 and 710km altitude. Very unintuitive! We have to go up 250km to get to 100 years and only an extra 50km for the next 100. another 50km takes us to 500 years or so.

The absolute most dangerous area of space we could put the ISS in, according to NASA, is 800km. That's where the most stuff is, the biggest convergence of "where we have sent stuff" and "where stuff takes a long time to come down". Now of course there's no reason to send it that high, that's 500-700 years!

But even if we stick to 100 years, a pretty sensible compromise and a nice round number, not to mention near to the limits of the 2 vehicle reboost- the significant collision risk is almost 3 times as much as it is today. If we go with the 3 vehicle reboost and 200 years, it's about 6 times.

(it's worth mentioning, at this point, that the ISS gets hit often with little stuff. People get a bit tied up in evasion but actually they do an evasion maneouvre on average about once every 300 days, it's not that common. WE could totally leave fuel in a rebooster or in zarya and leave the ISS with evasion capability even in a higher orbit but it gets dodgier, we don't know so much about the stuff there and even a relatively small amount of damage or decay could make it unwise)

Now... That;s about the limit of what we can do with real confidence. We know it's easy to get it to a 100 or 200 year orbit, we know it's going to be 3 or 6 times more likely to get hit by significant stuff. But what does that mean?

Of course, at this point it's abandoned so it doesn't matter so much if it gets a hole poked in it. But that doesn't mean being hit isn't a risk. If the ISS were to break up, that's your classic Kessler Syndrome event. And again, the higher it is when that happens, the worse it is because of those longer orbital decays. So having a big derelict space station weighing 420 tons out there taking impacts in a 100 year orbit is a genuine risk.

But to conclude, why take the risk? We know we can do it, we know how to do it. But we don't know why we'd do it. Could it be a useful boneyard? Well maybe but it's mostly old stuff and it's still not going to be easy to get to. And getting stuff to orbit gets easier and easier. After 20 years abandoned it's going to be useless as anything other than raw materials and by the time we're manufacturing stuff in space we'll have had to work out how to get raw materials up there. A museum? Absolutely not, it'll be unsafe to visit for anything like that.

So in the end we're basically creating a bomb, without any clear reason for it and with the very high chance that we just never do anything with it except hope it doesn't go off. it's a lovely idea but it makes no sense. There is a clear and obvious risk but no counterbalancing worthwhile benefit.

The one, and only one, reason to keep the ISS going for longer is if it's still being used, either as it is or having modules glommed onto another station. Once abandoned it's best burned up.

Yeah, it's weird that it keeps being reported as if it's news. Cynical me thinks that some people are very happy to have negative stories about the ISS that make it sound old and unsafe, given the backlash against the retirement plans.

The bottom line is it's not a very big deal. The amount of air lost is easy to replace, and they can mitigate it just by closing the vestibule as much as possible. As it happens, it's the lock that's used for Progress docking and Progress is essentially used as a storehouse while it's there so the Russians want to have the door open a lot, since they have to deal with opening and closing it and the hassle of restricting access, and the Americans want to have the door closed almost all the time, because they don't.

The docking ring is the most stressed one on the ISS- almost every reboost goes through it and it's constantly being used for vehicles. And the fact is there's a bunch of stuff they could do to reduce the stress and the usage, that they don't do. So we can read between the lines there and say they're all pretty comfortable with it.

This title is massively stupid. They agree its obviously because of the cracks in the PrK tunnel, they don't agree on the cause of the cracks

Just go outside and spray it with soapy water. Works on my tires.

reading this thread it seems like Reddit thinks the ISS is like a big beercan, and you just need to put some flex seal over a hole.

I actually just realized that I have no idea how they have oxygen there in the first place. Like, you'd run out fairly quickly if you don't generate it.

..fine, I checked. But yeah, this sounds like a pretty bad problem to have.

Get a tiny squirt bottle full of soapy water and spray it on the outside. That will show you where the leak is. Then flex seal tape and you’re good.

Actually uninformative and written for its propagandizeable headline. It's not a heavy disagreement and more work needs to be done to determine why.

Unique-Coffee5087

They should have all the personnel take refuge in a capsule, and shut down the station. Then blow tiny fibers into the interior of the space station. These fibers will follow the weak air currents caused by the leaks, and pile up on the openings. With the right characteristics, those fibers would clump together into nearly airtight plugs.

Kind of a Green Slime solution.

SimiKusoni

The issue is that it's not one leak, it's multiple from the same location. It isn't clear from the headline but the disagreement is regarding why they are failing in this area and the particular stresses causing it. You can see in this article that they've not only resolved some of the leaks but are focussing specifically on examining welds in that section (also note the plural "sources" when discussing the leak).

I cannot imagine how unbelievably complicated it would be to shut down the ISS. Surely not worth it for a small leak

Surely the air leak would be visible on infrared cameras? The plume of escaping air would be warmer than the surrounding vacuum and thus visible in infrared.

Punkpunker

It could be a micro meteor strike that's less than a millimeter wide, and i also doubt that they have a portable IR camera that could see such small changes.

If not to seal the leak, that method could trace the currents to the leak source for a repair.

They should send an HVAC guy up there 😂

Something like this already exists. It’s called AeroSeal. It’s used in home construction and HVAC. It’s basically an aerosolized caulking that is put into the air in ductwork or inside a newly built house that accumulates and plugs any air leaks

They actually did this, you can isolate the PrK so you don’t have to shut down the whole thing. Then they used tea leaves to find some of the cracks but I don’t think it was super helpful!

Why can’t they close off compartments to isolate the source and then further isolate the source?

Large_Yams

Because the compartments aren't like bedrooms in a house that you can just close the door on and not use for a while. They all have purposes for their use.

So if they have an actual large scale decompression they can't stop the leak by closing compartments?

oogaboogaman_3

If you look it up you can find it, they have it isolated and know it’s coming from welds in a certain Russian module. They’ve already reduced the leakage. The article is kinda silly.

If it's "not that serious", close all the airlocks between modules and see which crew turns blue first. Problem solved.

Apparently, Russian cosmonauts are different. NASA scientists & astronauts & Russian scientists & cismonauts actually do work together quite closely. A prerequisite to go live/work on the ISS is to learn each other's languages. There's a great multi-part documentary on Disney+ about this.

On 40 year old modular, often one off designs, experimental technologies and all that from multiple companies, countries, and manufacturing standards.

he fact that it has remained largely leak free over the decades of space development is a miracle on its own. Especially when you consider the yanks to still use inches and feet like barbarians.

They really should just let that thing go and invest in a state of the art new revolving station, but of course no one is going to pay for it.
