The Zvezda module was built in the mid 80s and was put into orbit in 2000. The ISS was planned to be deorbited in 2016 but that was extended to 2020 and then again to 2030. Makes sense if there are micro leaks as well because of how the ISS is boosted up by progress missions and you have the whole weight of the space station going though this module.
Thank you, finally an intelligent comment. I see too many people commenting about the leaking being somewhat shocked about it, but don't know the half of it.
Just a nitpick, but they don't need to support the entire weight of the station (you know, microgravity makes stuff seem weightless), just the thrust of the boosting vehicle (which does not need to be too high). Come to think of it, how come Starlink has ion booster thrusters and ISS doesn't?

If the leak is getting worse, that means the hole is getting bigger. That means that, if not fixed, the hole will inevitably result in explosive decompression once it gets big enough.
If it's already leaking, then as the hole gets bigger all that will happen is faster leaks. Explosive decompression would only happen if something that is not current leaking suddenly opens wide.

It would probably work if you knew where to put it (on the inside). I'd recommend the brush on kind though. Something about a spray-can in zero G just doesn't sound right lol.
What else would anyone expect? After going through extreme temp changes every 90 mins NASA couldn’t expect the ISS to last forever. They’ll push it to catastrophic extremes as they usually do 😮
If you are going to have a leak, having it in a docking port with 3 other spares available is the best you could hope for. yes this isn't good. But doesn't sound like it is catastrophic, since they can just seal it off permanently.
Isn't Russia supposed to abandon the ISS at the end of the year? Because they are planning a new spacestation in cooperation with China. Edit -- I see that Russia agreed to stay until 2028... since the ISS would have to be abandoned if Russia was no longer providing the supplies it needs.
Enjoying Blue Origin’s turtle march towards reliable high-quality space vehicles. Getting it right from day one is very important for customers, and these guys are looking good.
BTW I like Axiom's idea of building new station atop the old one and separating later. I get that pressurised modules are old and leaky and unreliable. But why can't we use ISS' solar panels? Can't we move them with the Truss to a new station?
I doubt they were designed to be detachable. They might be a bit too securely attached, with circuits embedded into the spacecraft body itself. You know how every kg sent up there costs tens of thousands of dollars. They optimise everything for weight. Even if you could somehow remove them and attach them to your new space station, the solar panels are old. Not only do solar panel efficiency drop over time, they were less efficient to start with, due to progress on the tech. Removing and reattaching them is not easy. There is no workshop in space. Doing the job in spacesuits just adds to the difficulty. And danger. Imagine your angle grinder slips and makes a big hole in your spacesuit. You'll die. You can't send handymen. The transport fees would kill your budget. You'd have to use the professional astronauts. Their times are expensive, and they have better things to do with their time. And do you really want to bodge some old solar panels to your new space station. Imagine they were somehow not properly attached, and you boosted your station (like you have to do periodically), and it came loose, fall off, pivots, crash into your station, and makes great big holes in multiple segments. Did I mention how hard it is to cut and weld stuff up in space, to fix the damage?
ISS vs China's spacestation is like compare US subway to chinese subway ;) It was a nice run (west) now it's over, the punchbowl is empty, no refills coming :P
The Chinese space station literally uses Soviet/Russian space module designs that bought in the 90's and 00's. The literal core module of Tiengong is a DOS-8 module, the same module as the Russian Zvevzda on ISS as an example. The only real difference is the modernized electronics. China needs to learn how to innovate themselves if they want to progress further than the west. Because currently they fly their astronauts on rockets using Russian engine designs, on a Russian Soyuz copy, using Russian flight suits, to space station built with Russian module designs and then they take an EVA using a Russian spacesuit copy the day after. There's nothing chinese about their space program currently. Just refurbished, modernized Soviet/Russian technology.
03:25 China Lunar EVA suit: It's all fine if the inside and outside of the suit are at ambient (room) pressure. Are we sure that the demo video had the suit between ~4-6 PSI *above* the ambient pressure in the room during that "mobility demo"? I also wonder this about the Artemis III suit shown. This stuff matters a lot!
There’s a technique called spray welding that on Earth you can use to put a new layer over an old layer of metal. It should not be run in an atmosphere that has a high oxygen content otherwise there would be a catastrophic flame. The tool runs around a central axis and can follow a contour. May be worth consideration for the space capsule.
Weight of the machine and personnel trained in this method of welding is probably the most major prohibiting factor from any agency being able to do repairs like you described in space.
You’ll only get a heavily edited propaganda video with some lady hysterically narrating about the greatness of dear leader. None of it will be live raw footage. They’ll ”find” some rock or relic associated with claims of them owning the moon, and anyone disagreeing can expect a nuke. The Chinese are people who help Russia in destroying hospitals in Ukraine.
As far as I know, the ISS was not meant to last this long. I think it would be a good thing if multiple replacements were launched and assembled, and the ISS retired.
The housing industry uses a spray liquid that finds and seals house leaks it is very affective at sealing air leaks. Seal off the corridor and allow it to find and seal the leak. Then put a metal fiber reinforced patch over the sealed leak. I think I will forward this to NASA.
It is pounds per day... Like a gram an hour...a gram of air...these are most likely old metal cracking due to thermal expansion and everything hitting the iss...it can be as much as an over tighten bolt losing a thread
@@josephcorcoran8714 officially they said it was done during assembly on ground...not sure they can drill up in space...and no one notices it's very cramped space burthen again iss is notorious about tools constantly getting lost lol
Maybe build standard of bolt tightening , did not take into account Earth standards can be excess in gravity and worse than excess in vacuum of space. Pressure inside plus vacuum outside , doubles need for special flexible seals. Expansion and contraction in varying polar push and pull in orbits.
@@danielch6662 If you want to differentiate like that, that is fair. But in the video it was stated as "port" without any differentiation (I will remove the "docking" from my comment, because you are correct, of course). :)
Space X Starship could replace the complete ISS with two expendable Starships, and a centralized docking module facility between the two ships. It would instantly replace and modernize the aging ISS with a new spacious facility. It would be a perfect test for the eventual Mars capabilities of Starship.
I think the most probable cause for the leak is an external welding default and it looks simpler to replace all that particular unit if it's cost-effective this way: Or it could be a case of hiding information from the other partnership member, for economic or other reasons.
Don't believe the channel. It's not hidden. Information has been public all this time. It's not their fault or anything in their control if the news stations you watch choose not to highlight it.
Amazing, wasn’t this air leak situation in a movie? A space craft gets hit with a small sized meteor shower punching the ship. The crew suites up and they release a colored gas. A guy on the outside spots the colored gas and is welded. I don’t know what 3lbs of O2 per hour would look like. I guess it’s serious enough to close the pathway. It sounds like a stress crack if it is slowly getting worse. Which means it’s at either connected end. I say color gas it up or make the area humidity higher so it would freeze as it was released 🤷♂️. Two years and they can’t find the leak?
New Glenn is not really a competitor to Starship as was never intended to be. New Glenn is effectively a heavy-lift Falcon 9 and could become the first real competitor to Falcon 9 in terms of cost-per-kilogram. Starship is a different class of vehicle and is really terrible at orbits between LEO and Interplanetary, but if it achieves its goals it will be untouchable in LEO delivery costs while also offering interplanetary access with on-orbit refueling. On-orbit fuel will be very expensive even with Starship's efficiencies, however, and that portion of the program remains a challenge. To make Starship competitive for higher Earth orbits, it will need a 3rd stage vehicle and payload bay doors that allow delivery of such cargo. We have yet to see any payload bay large enough for such vehicles and even the tiny slot for Starlinks has required substantial reinforcement to endure launch and landing forces. I've heard no one discussing this issue, but getting large payloads in and out of Starship remains a major challenge.
The ISS was originally going to be MIR2 but then the Soviet Union collapsed. The US decided to help build the ISS to keep post-Soviet Russian rocket scientists from seeking employment in Pakistan and Iran.
I am glad Rocket Lab's newly build ESCAPADE spacecraft will not be flying on New Glenn. (Yeah. Didn't you know? Rocket Lab built both of those spacecraft for NASA.) That is the problem with building very expensive, slow to construct, rockets. You are unwilling to test them with a mass simulator. I think it is kind of looney for BO to test a second prototype inside the fairing of the New Glenn. That way if it explodes or goes into a parabolic trajectory, you can destroy 2 PROTOTYPES FOR THE PRICE OF ONE FLIGHT. Great plan. And of course comparing New Glenn's capabilities to Super Heavy is sort of an academic exercise since the Super Heavy / Starship is now just a boilerplate and New Glenn has yet to fly. Talk about capabilities after they have been proven. Yes, Starship is just a BOILERPLATE vehicle. Just for comparison, the boilerplate Apollo spacecraft was tested in 1966, which was 3 years before Apollo 11 and 2.5 years before Apollo 7 and 8. And that was back when NASA worked at SpaceX development speeds, with Werner at the helm of booster development and practically unlimited funds and a nice HARD deadline, rather than the squishy "maintain the capability" programs we have today.
And of course there is no feasible plan to evacuate the amount of ISS occupants that are on board if such a measure became necessary. Quite a few this time around.
When I have an old car and dont want it anymore and it springs a leak: I let it go until the car doesn't run anymore. If I do want to keep the car, I take care of the leak. Apparently, nobody wants the ISS anymore.
They've looked for the leaks, and can't find it/them. And with the ISS being retired in just a few years, there's not a lot of reasons to do much about it now, if they find it The module can do most of its job either way. A mild inconvenience for 5 years, or spend hundreds of millions over probably a year or 3, and still retire it in a few years.
I bought a Chinese, battery powered chain saw. After about fifteen battery discharges the trigger started malfunctioning and eventually failed. Upon inspection, I discovered they use a "unconventional" variable speed technique different than we would use in the west. I could not obtain a replacement switch anywhere and the company discontinued that model and subsequent support! This is typical for Chinese purchased products in my experience!!! It is cheap in many ways!!!! You could not catch me on that space craft!!!
China only makes what the west want to buy. If you want quality they most certanly can make it but you want cheap and they will happily build cheap just like every other company or country. Bought plenty of cheap US or European products that broke down just like Chinese cheap crap.
Just how do you think they make it so cheap? Magic? They cut a corner here, cut a corner there, optimize everything 3 times more than they should. If you are paying $50 for a chainsaw, and everybody along the supply chain is to make a profit, it has to leave the factory below $10. Do you realize how hard it is to hit that price point? The skill of the engineers is astounding. An engineer's job is not to make anything as robust and high quality as possible. The market for customers with bottomless wallets is extremely limited. In any engineering job, you have to work within constraints you are given. And one ever present critical constraint is the budget you have to work with. For both the R&D, and the marginal cost.
You are saying you're poor without saying you're poor, Chinese make their products' quality according to the order of the merchants and purchasing agents.

looks like China is going from strength to strength in space exploration whereas US is in a gradual decline from the height of their moon mission. Back in the 60s, who would have though that after another 60 years, US will have so much trouble transporting their Astranauts into low orbit.
The US already did it… like you said 60 years ago. One (private) American company is having issues and China is still trying to copy their plane from 40 years ago… and China still hasn’t been on a single manned moon mission. Your comment is purely political not technical.
Yep. This is some lame kind of please think of it this way crap. No dude, people don’t spend huge sums of cash or hurry off to do things that have already been done. China is just doing it for politics. If there were more to be gained from going to the moon there would be 5 or so country’s crawling over it like ants.
@@TheScottbb1 you're trying to live off past glories. The US today is in exactly the same place as China when it comes to landing anybody on the moon. Neither of them can.
@@TheScottbb1your extremely biaised on the political part and extremely wrong on the technical part so don't start speaking nonsense when you don't know what you're talking about.
@@TomDrez im not even American so it’s not political for me and we’re not seeing multiple companies in China reusing or trying to reuse their rockets let alone developing something like the Starship. I just don’t get where you’re coming from. In the US the limiting factor is money but in China the limiting factor is technology and experience.
I'm rooting for china they have been making great progress with landers and satellites. We need more nations in space!
I'm not sure anyone other than them wants commies in outer space 😂😂
@@JohnWiku Commies were the first in space, keep crying🤣
Call the FAA! After all they are all about safety
Love the exquisite sarcasm!!! Well done!
The thing is out of the atmosphere. The FAA doesn't care. Until it comes back in.
Where is the flex seal guy?
Flex Seal
It would probably work if you knew where to put it (on the inside). I'd recommend the brush on kind though. Something about a spray-can in zero G just doesn't sound right lol.
I wanna see Phil Swift in the space station selling his Flex Tape.
What else would anyone expect? After going through extreme temp changes every 90 mins NASA couldn’t expect the ISS to last forever. They’ll push it to catastrophic extremes as they usually do 😮
The Boeing Starliner did it.
If you are going to have a leak, having it in a docking port with 3 other spares available is the best you could hope for.
yes this isn't good. But doesn't sound like it is catastrophic, since they can just seal it off permanently.
Need some more duct tape up there.
Isn't Russia supposed to abandon the ISS at the end of the year? Because they are planning a new spacestation in cooperation with China.
Edit -- I see that Russia agreed to stay until 2028... since the ISS would have to be abandoned if Russia was no longer providing the supplies it needs.
Enjoying Blue Origin’s turtle march towards reliable high-quality space vehicles. Getting it right from day one is very important for customers, and these guys are looking good.
Russian construction... shocking! Chinese armor suits... from a Russian design... they can keep them. NewGlenn can't do anything, yet.
I'm not surprised to see a comment like this from a face like you
BTW I like Axiom's idea of building new station atop the old one and separating later. I get that pressurised modules are old and leaky and unreliable. But why can't we use ISS' solar panels? Can't we move them with the Truss to a new station?
There's probably lots of equipment on board that could be reused, but NASA likes to buy new stuff.
I doubt they were designed to be detachable. They might be a bit too securely attached, with circuits embedded into the spacecraft body itself. You know how every kg sent up there costs tens of thousands of dollars. They optimise everything for weight.
Even if you could somehow remove them and attach them to your new space station, the solar panels are old. Not only do solar panel efficiency drop over time, they were less efficient to start with, due to progress on the tech.
Removing and reattaching them is not easy. There is no workshop in space. Doing the job in spacesuits just adds to the difficulty. And danger. Imagine your angle grinder slips and makes a big hole in your spacesuit. You'll die. You can't send handymen. The transport fees would kill your budget. You'd have to use the professional astronauts. Their times are expensive, and they have better things to do with their time.
And do you really want to bodge some old solar panels to your new space station. Imagine they were somehow not properly attached, and you boosted your station (like you have to do periodically), and it came loose, fall off, pivots, crash into your station, and makes great big holes in multiple segments. Did I mention how hard it is to cut and weld stuff up in space, to fix the damage?
The American stick is a great idea, could be useful on many occasions 👍
The Chinese may get to the Moon well before the Americans return there, they seem to have the will and the backing of their government to do so.
Why don't those space suits have a glaring spotlight shining into the astronauts' eyes, like they do in every single sci-fi movie ever made?
Send up a halloween fog machine and put an external camera on the ISS.
ISS vs China's spacestation is like compare US subway to chinese subway ;)
It was a nice run (west) now it's over, the punchbowl is empty, no refills coming :P
The Chinese space station literally uses Soviet/Russian space module designs that bought in the 90's and 00's. The literal core module of Tiengong is a DOS-8 module, the same module as the Russian Zvevzda on ISS as an example. The only real difference is the modernized electronics.
China needs to learn how to innovate themselves if they want to progress further than the west. Because currently they fly their astronauts on rockets using Russian engine designs, on a Russian Soyuz copy, using Russian flight suits, to space station built with Russian module designs and then they take an EVA using a Russian spacesuit copy the day after.
There's nothing chinese about their space program currently. Just refurbished, modernized Soviet/Russian technology.
Ducktape and bubble gum... fixed
You mean another layer of steel
Plumber's putty also works great and of course, tape. I watched a guy do that to my disposal.......Looking dry.
03:25 China Lunar EVA suit: It's all fine if the inside and outside of the suit are at ambient (room) pressure. Are we sure that the demo video had the suit between ~4-6 PSI *above* the ambient pressure in the room during that "mobility demo"? I also wonder this about the Artemis III suit shown. This stuff matters a lot!
There’s a technique called spray welding that on Earth you can use to put a new layer over an old layer of metal. It should not be run in an atmosphere that has a high oxygen content otherwise there would be a catastrophic flame. The tool runs around a central axis and can follow a contour. May be worth consideration for the space capsule.
It would probably be cheaper to build and send up another Zvevda instead of trying to make this machine work up there.
Weight of the machine and personnel trained in this method of welding is probably the most major prohibiting factor from any agency being able to do repairs like you described in space.
In my experience with bike tires & tubes, leaks never fix themself without some intervention.
I really look forward to China's high tech moon missions - with 4k visuals! 😍
You’ll only get a heavily edited propaganda video with some lady hysterically narrating about the greatness of dear leader. None of it will be live raw footage. They’ll ”find” some rock or relic associated with claims of them owning the moon, and anyone disagreeing can expect a nuke. The Chinese are people who help Russia in destroying hospitals in Ukraine.
As far as I know, the ISS was not meant to last this long. I think it would be a good thing if multiple replacements were launched and assembled, and the ISS retired.
2031
yeah i hear it was planned to be deorbited in 2016 then 2020, now 2030, or 2031. then it'll probably get boosted 2050 or something lol.
Superb
Flexseal to the rescue
Varying foot width is why quality shoes are made in various widths, typically from AA to EEEE. Maybe demand more accurate ads?
The housing industry uses a spray liquid that finds and seals house leaks it is very affective at sealing air leaks. Seal off the corridor and allow it to find and seal the leak. Then put a metal fiber reinforced patch over the sealed leak. I think I will forward this to NASA.
07:40
Our Moon is also not gravitationally bound. (It's also a quasi-satellite).
have they found drilll marks??
It is pounds per day... Like a gram an hour...a gram of air...these are most likely old metal cracking due to thermal expansion and everything hitting the iss...it can be as much as an over tighten bolt losing a thread
Did they ever come out with a conclusion as to how the drill hole got there back when that anomalous hole was discovered?
@@josephcorcoran8714A crazy woman. They don't like to talk about it publically.
@@josephcorcoran8714 officially they said it was done during assembly on ground...not sure they can drill up in space...and no one notices it's very cramped space burthen again iss is notorious about tools constantly getting lost lol
@@qa1e2r4 You think a pound is 24 grams? Americans...
Maybe build standard of bolt tightening , did not take into account Earth standards can be excess in gravity and worse than excess in vacuum of space. Pressure inside plus vacuum outside , doubles need for special flexible seals. Expansion and contraction in varying polar push and pull in orbits.
Small oversight, I believe, at 1:46: There are four ports on the US segment of the ISS, meaning a total of eight for the entire station.
I thought there were 4 docking ports on the Russian segment, and 2 on the US segment, plus 2 more _berthing_ ports on the US segment.
@@danielch6662 If you want to differentiate like that, that is fair. But in the video it was stated as "port" without any differentiation (I will remove the "docking" from my comment, because you are correct, of course). :)
Space X Starship could replace the complete ISS with two expendable Starships, and a centralized docking module facility between the two ships. It would instantly replace and modernize the aging ISS with a new spacious facility. It would be a perfect test for the eventual Mars capabilities of Starship.
Today tech has developed so far, you never know where surprises come up
I think the most probable cause for the leak is an external welding default and it looks simpler to replace all that particular unit if it's cost-effective this way: Or it could be a case of hiding information from the other partnership member, for economic or other reasons.
Don't believe the channel. It's not hidden. Information has been public all this time. It's not their fault or anything in their control if the news stations you watch choose not to highlight it.
Send duct tape with the next mission
Super Tape that Guy uses on Boats ..have to keep it Warm ..😂
Amazing to see BOs vaporware potentially fly. Landing...we'll see.
Amazing, wasn’t this air leak situation in a movie? A space craft gets hit with a small sized meteor shower punching the ship. The crew suites up and they release a colored gas. A guy on the outside spots the colored gas and is welded.
I don’t know what 3lbs of O2 per hour would look like. I guess it’s serious enough to close the pathway.
It sounds like a stress crack if it is slowly getting worse. Which means it’s at either connected end.
I say color gas it up or make the area humidity higher so it would freeze as it was released 🤷♂️.
Two years and they can’t find the leak?
Spray hairspray ground that area and it should plug the micro cracks
I'm guessing that NASA didn't spring for the extended warranty?
Seriously, we repair vacuum chambers with spray paint cheap hardware store, Krylon spray paint. They should paint the inside of the crack.
liquid sealant
As it de orbits over time atmospheric pressure would cause welding to leak?, sending it higher up could make it able to be repaired as a project?
I visited the China Space Museum in Beijing and apparently China went to the moon in the late 1960s too.
I wonder if they had the same engineers as did the Titan submersible. Engineers that buckle under pressure. Yes, pun intended.
New Glenn is not really a competitor to Starship as was never intended to be. New Glenn is effectively a heavy-lift Falcon 9 and could become the first real competitor to Falcon 9 in terms of cost-per-kilogram. Starship is a different class of vehicle and is really terrible at orbits between LEO and Interplanetary, but if it achieves its goals it will be untouchable in LEO delivery costs while also offering interplanetary access with on-orbit refueling. On-orbit fuel will be very expensive even with Starship's efficiencies, however, and that portion of the program remains a challenge.
To make Starship competitive for higher Earth orbits, it will need a 3rd stage vehicle and payload bay doors that allow delivery of such cargo. We have yet to see any payload bay large enough for such vehicles and even the tiny slot for Starlinks has required substantial reinforcement to endure launch and landing forces. I've heard no one discussing this issue, but getting large payloads in and out of Starship remains a major challenge.
Simple life lesson. LEAKS NEVER GET BETTER ONLY WORSE
The ISS was originally going to be MIR2 but then the Soviet Union collapsed. The US decided to help build the ISS to keep post-Soviet Russian rocket scientists from seeking employment in Pakistan and Iran.
i think in space is some new unknowns law of physic, maybe material change shape in space
I hope that it will be fixed and restored to proper operation.
Where's the Flex seal?
I am glad Rocket Lab's newly build ESCAPADE spacecraft will not be flying on New Glenn. (Yeah. Didn't you know? Rocket Lab built both of those spacecraft for NASA.)
That is the problem with building very expensive, slow to construct, rockets. You are unwilling to test them with a mass simulator. I think it is kind of looney for BO to test a second prototype inside the fairing of the New Glenn. That way if it explodes or goes into a parabolic trajectory, you can destroy 2 PROTOTYPES FOR THE PRICE OF ONE FLIGHT. Great plan.
And of course comparing New Glenn's capabilities to Super Heavy is sort of an academic exercise since the Super Heavy / Starship is now just a boilerplate and New Glenn has yet to fly. Talk about capabilities after they have been proven.
Yes, Starship is just a BOILERPLATE vehicle. Just for comparison, the boilerplate Apollo spacecraft was tested in 1966, which was 3 years before Apollo 11 and 2.5 years before Apollo 7 and 8. And that was back when NASA worked at SpaceX development speeds, with Werner at the helm of booster development and practically unlimited funds and a nice HARD deadline, rather than the squishy "maintain the capability" programs we have today.
A simple fog generation and micro camera placed externally will solve this..
Micro leaks mean metal fatigue. Which means new leaks will open with time. Its like old rubber that became brittle and started to crack.
@@COGintheMachine the ISS needs a pension.
And of course there is no feasible plan to evacuate the amount of ISS occupants that are on board if such a measure became necessary. Quite a few this time around.
Just use some Flex Seal. Works eveytime.
I know most of your audience is American, but it just irritates me when you talk about NASA and ISS in pounds instead of kilograms.
New glen. Big boom😮
When I have an old car and dont want it anymore and it springs a leak:
I let it go until the car doesn't run anymore.
If I do want to keep the car, I take care of the leak.
Apparently, nobody wants the ISS anymore.
They've looked for the leaks, and can't find it/them.
And with the ISS being retired in just a few years, there's not a lot of reasons to do much about it now, if they find it
The module can do most of its job either way.
A mild inconvenience for 5 years, or spend hundreds of millions over probably a year or 3, and still retire it in a few years.
@@RobertPruitt-y7m Thanks for the info Captain Obvious...
^.^
Why not just glue an additional air tight layer on the inside to stop the leak?
It has been leaking for years and years.. old news...
13:17 Wait, did they paint it? I thought the heat protection was unpainted.
They just need an enormous 3d printer up there and they can start printing starship parts.
Superglue and bakingsoda
I bought a Chinese, battery powered chain saw. After about fifteen battery discharges the trigger started malfunctioning and eventually failed. Upon inspection, I discovered they use a "unconventional" variable speed technique different than we would use in the west. I could not obtain a replacement switch anywhere and the company discontinued that model and subsequent support! This is typical for Chinese purchased products in my experience!!! It is cheap in many ways!!!! You could not catch me on that space craft!!!
😂😂😂
China only makes what the west want to buy. If you want quality they most certanly can make it but you want cheap and they will happily build cheap just like every other company or country. Bought plenty of cheap US or European products that broke down just like Chinese cheap crap.
Just how do you think they make it so cheap? Magic? They cut a corner here, cut a corner there, optimize everything 3 times more than they should. If you are paying $50 for a chainsaw, and everybody along the supply chain is to make a profit, it has to leave the factory below $10. Do you realize how hard it is to hit that price point? The skill of the engineers is astounding.
An engineer's job is not to make anything as robust and high quality as possible. The market for customers with bottomless wallets is extremely limited. In any engineering job, you have to work within constraints you are given. And one ever present critical constraint is the budget you have to work with. For both the R&D, and the marginal cost.
Well, of course you prefer a ship from boeing.
You are saying you're poor without saying you're poor, Chinese make their products' quality according to the order of the merchants and purchasing agents.
Send up a can of coca cola, shake in the module, open and follow the bubbles to the leak.
FlexSeal to the rescue
Given the leak is in the Russian section, I think they'd call it a 'special venting operation'.
Years of investigation and they can't find the leak? They can't narrow it down to which port is leaking? How hard Is it to narrow down
It cracks before it breaks and fails.
JUST MIXING SOAP AND WATER AND LOOKING FOR BUBBLES ARE USING A DYE AND LOOKING FOR COLOR LEAK
