Probably better to link to the article, rather than a thread that has 0 comments.

"The air leaks escalated on Friday from a pound of air per day to two pounds, according to a senior NASA official who asked not to be named.

Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikayev were using a saw to break into an area where they believed they could access the crack leaking air, the NASA official said.

NASA officials disagreed with this method, the NASA official added, prompting mission control in Houston to order safe-haven procedures."

Why would I steal a link from someone who submitted a story first and take credit? I know it's normal behavior in tech to stab everyone in the back but...
cucumber3732842•1h ago
Super thin margin stuff like space flight only "works" because they cross their Ts and dot their Is. There's probably no danger here, the repairs will probably go fine and be uneventful, but you gotta treat every situation like it's the real deal because otherwise it'll get you when it does happen.
ggm•47m ago
Agree to precautionary principle. Disagree to certainty of fixing because this is a long standing leak which just doubled in intensity: either it got bigger, or there are more. Either way, we have no reason to be optimistic a bigger leak problem has a faster MTTR or even triage.
jmount•56m ago
I have to say worrying about the provenance of writing has made me a grumpier reader.

For example: "The space station is made up of Russian and US segments, and there are modules from the European and Japanese space agencies too." It feels like this sentence is inserting some points, but is lacking in authorial intent. Is the intent to say the station is largely Russian and US, or to say the station has more than two partners? Probably an okay sentence, but still feels like a stone in the shoe.

kylecazar•50m ago
Yeah, this is their "live reporting" feed, where updates and context get posted about an in-progress event.

I don't think you'll find that type of language in the more traditionally published/edited articles.

ShinyLeftPad•47m ago
Seeing nothing wrong with it. If journalist follows inverted pyramid, it starts with crucial facts and at the end it can be mostly supplementary information. Seeing this is about "International Space Station", this adds context to why it is called "international" for an ordinary person.
Polizeiposaune•27m ago
It's complicated. The US Orbital Segment of the ISS consists of modules funded by and built in the US, ESA, and Japan.

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

Several of the US modules were built in Europe by Thales Alenia Space and were transferred to the US in exchange for the US launching the European modules on the Space Shuttle.

Imagine something like this happening halfway to Mars and zero chance of escaping, getting any help or parts sent to you.
willy_k•35m ago
There is less debris around on the way to mars and this is a known and worsening for the ISS due to its age.
ShinyLeftPad•33m ago
Debris from what? Satellite debris get in that orbit?
vel0city•20m ago
Debris from space. Lots of rocks are constantly falling from space from all over. Sometimes they're big and make pretty lights in the sky as they fall, often they are practically invisible.
pixl97•18m ago
Most of the things that will be a common danger (that is too small to track) are tiny pieces of stuff. Think paint chips and sand grain sized objects. These can be from things that came off rockets and ships, and things we've left behind like experiments and satellites. When these tiny things intercept you at many kilometers per second it can be dramatic.

Anything larger, say a lost screw driver, would punch thru the ISS like it wasn't even there leading to some ugly consequences.

wat10000•17m ago
Bits of spacecraft falling off (Challenger's windshield was famously cracked by a paint chip), debris from satellite collisions, even anti-satellite weapons tests.
gwbas1c•33m ago
Maybe someone who knows more about the ISS than I do can answer this:

Naively, I would assume that there are airlocks between the different sections of the ISS. I would also assume that they would close these airlocks while doing the kind of work they are doing to repair the leaks.

So, assuming I'm right (and my assumptions might be wrong,) why do the astronauts need to shelter?

bmelton•28m ago
Well, I won't claim to know the answer, but "please do not move between different airlocked sections while this work is underway" sounds a lot like the definition of "shelter" to me
gpm•10m ago
In this case, per the article, "shelter" meant "shelter in a capsule capable of returning to earth and put on the spacesuits that you wear during return to earth".

I.e. leaving the actual ISS structure entirely.

bmelton•5m ago
I would guess they're worried about breaking something, but thanks for the clarification (and apologies for not having RTFA)
ocdtrekkie•28m ago
I think the service module is both structurally and functionally critical. If it is failing and you do not know why, catastrophic failure is presumably possible, not just some air loss. A hole or crack in the module is now apparently double the size it was until recently, that is a trend that presumably could continue to rapid unscheduled disassembly.
kaicianflone•23m ago
I don’t have a dog in the fight but it’s super scary to think about for the astronauts and their families. This issue’s been going on for a while now. Surprised that there’s not more AI or robotics that could be utilized for such cases.

Rumors are that Elon gets spaceX to buy tesla so tele-operated Optimus robots do the hard space work from now on. Not a bad idea per se but I’m not educated on the topic. Curiosity has me asking if we really want humans to go to mars or in space at all.

I think it's an attempt to express that the station consists of only two segments: Russian (ROS) and US (USOS), but the US invited its allies to work together on its segment. So parts of the USOS are made in Europe, Canada and Japan, and generally lifted to space by the US, usually on the Space Shuttle.

(All this was pretty lucid of the US, but obviously the Russians did no such thing on their side. The Japanese even managed to get an ISS resupply mission launched on their own vehicle, which is no small achievement, and the ESA did a bunch of good science. And what would space be without the Canadarm :-)

threwrfaway•27m ago
A top (arguably, the top) metallurgist who studied previous failed parts told me it's corrosion of the Russian alloy used.

Corrosion is a hard problem in living quarters (ie moisture and salt) in space (sealed with no gravity)

SlightlyLeftPad•7m ago
I was wondering about this as well. In theory, there are also some metals and compounds that react with each other with just simple contact which result in some kind of amalgamation which can result in disastrous structural loss. Veratassium recently did a video on this kind of effect[1]. Could this be happening here?

[1]: https://youtu.be/ksn5yrsC3Wg

sigmoid10•35m ago
Seems like these structural integrity problems are always inside the Russian section. So if you're on a Russian mission to Mars, yes it would be reasonable to be worried. Otherwise this seems like a non-issue.
ofjcihen•33m ago
Ah yes, the well traveled and highly tested human mission to Mars.
sigmoid10•29m ago
The 10 non-Russian modules have been in vacuum for a quarter century and have done just fine despite facing more debris than in interplanetary space. So yes, this aspect is well tested. This stuff is literally part of the reason why the ISS exists in the first place.
threwrfaway•22m ago
The hubris of forgetfulness; to think that until Elon showed up the West couldn't even put a person in space anymore.

The Soyuz, the MIR, the human space records, the Venera program, closed cycle rockets, all have no equivalent in the West. Even their version of the shuttle was superior (it flew 100% autonomously).

I don't like Musk, but he single handedly saved the Western space programs.

sigmoid10•13m ago
This sense of national pride based on long past achievements will always be bewildering to me. Do you really think a country that is actively engaged in a full scale open land war and whose economy is in shambles is able to maintain (much less build) a venerable space program? Elon might have saved the American tax payer from the senate launch system jobs program, but the majority of the global space industry is and always has been in the west. Russia has been an afterthought since the collapse of the Soviet Union. And it shows in everything they have done in space since.
bobim•5m ago
I didn't realize Buran flew, and flew autonomously. Impressive for the times.
tedivm•30m ago
This is just not true. There have been leaks due to micrometers in just about every section of the ship at one point or another. A quick search pulls up examples of US modules having issues, especially around interfaces and seals. NASA had a whole investigation between 2018 and 2021 about the recurring issue.
sigmoid10•22m ago
This is just wrong. All serious issues that turned out to be safety concerns were in Russian modules. The 2018 leak you refer to here was in a Soyuz capsule and the 2021 leaks were in the Zvezda module (same place they are this time). In between there were also minor leaks in the Zvezda connection tunnel.
threwrfaway•15m ago
If you count the Soyuz leak, then the Boeing counts too! That was far more serious than anything you listed.

Two astronauts stranded for nine months taking the ISIS supplies intended for others. This is after they safely docked, which was considered risky at the time.

sigmoid10•11m ago
You brought it up. I have been talking about structural issues with long term core modules. And that is clearly a Russian issue.
pantalaimon•15m ago
Maybe we can use the goop from those self sealing bike tires to have self sealing space station modules
threwrfaway•19m ago
Unless your spacecraft is built by Boeing.

We had two astronauts stranded in space for the better part of a year just last year!

extraduder_ire•21m ago
The Zvezda module has been in orbit since July 2000.

I don't think any crewed interplanetary mission is going to last that long for the foreseeable future.

866-RON-0-FEZ•18m ago
They're not flying to Mars in a 30 year old Russian rust bucket so
sizzzzlerz•18m ago
Sort of like what happened on the Apollo 13 mission in 1970. Engineers on the ground were able to devise a makeshift fix to adapt the control module airscrubber filters to fit the lunar module so the astronauts could shelter in the LM for several days before getting back into the CM and coming home.
SoftTalker•13m ago
Yeah I was thinking about that, the big difference being that you are months out instead of hours/days, if a return to Earth is even possible.
himata4113•25m ago
Compression loss can lead to a decompression of sorts if I had to guess... it is a vaccum out there. The force from a decompression can yield a chain reaction or strongly disrupt the entire station.
MrPouig•20m ago
If things go wrong, they're already in the véhicule supposed to bring them back. It might be upsetting to be 3 locked doors away from your best way to come back home
bArray•4m ago
This is the right answer - if it goes wrong they are already placed in the escape vehicle, sitting in their space suits.
Polizeiposaune•15m ago
There are normally-open air-tight hatches between modules. Various utility connections and air ducts are normally run through the open hatches so it would take a bit of work to disconnect these connections before they could be closed.

Not exactly something you want to be doing under time pressure.

basch•14m ago
What’s the reason against separate conduit for utilities?
NegativeLatency•10m ago
Just a guess: Harder to build and operate with more failure modes and less opportunity for intervention.
nkrisc•10m ago
Those would need to be connected during docking and sealed separately anyway if you wanted to seal the hatch. More failure points.
gpm•9m ago
You'd still need to pull out the utilities and close a now second hatch in the conduit to seal the thing. What would be the point?
Zigurd•8m ago
If such a conduit would connect two sections that the hatch is meant to isolate, you would have to make the conduit and everything running through it airtight, even under a catastrophic loss of air. If the conduit didn't seal as well as the hatch, which is meant to withstand hard vacuum on the other side of it, it would defeat the purpose of the hatch.
ianburrell•13m ago
There aren’t even doors between sections. Airlocks are serious things, there is one or two for station for EVA. There are multiple hatches for docking spacecraft.

One of the innovations of ISS is larger docking adapter with bulkhead that is removed after docking. Russian section still uses hatches. All of the cables go through the docking adapter or hatch which makes impossible to close door or quickly disconnect.
