The transfer tunnel, known by the Russian acronym PrK, connects the Zvezda module with a docking port where Soyuz crew and Progress resupply spacecraft attach to the station.

Air has been leaking from the transfer tunnel since September 2019. On several occasions, Russian cosmonauts have repaired the cracks and temporarily reduced the leak rate. In February, the leak rate jumped up again to 2.4 pounds per day, then increased to 3.7 pounds per day in April.

"The Russian position is that the most probable cause of the PrK cracks is high cyclic fatigue caused by micro-vibrations," Cabana said on November 13. "NASA believes the PrK cracks are likely multi-causal, including pressure and mechanical stress, residual stress, material properties, and environmental exposures."

Crew members aboard the space station are keeping the hatch leading to the PrK closed when they don't need to access the Progress cargo freighter docked at the other end of the transfer tunnel. Russian cosmonauts must open the hatch to unpack supplies from the Progress or load trash into the ship for disposal.

As a precaution, Barratt said space station crews are also closing the hatch separating the US and Russian sections of the space station when cosmonauts are working in the PrK.

It's the I-SSsssssssssssssssssss

Because there’s a hole in it, stupid.

That’ll be five million dollar bucks for my consultation.

[–] [email protected] 3 points 3 hours ago

But the hole is on the Russian side and the Russian side is absolutely perfect. No holes here, Comrade, breathing is a luxury some people do not get. Do not become one of those non-breathers Comrade.

Line-item breakdown:

Fix-a-flat, $5.

Knowing where to squirt, $4,999,995.

Teenage me could have figured that out in a couple days, if you fire enough bullets eventually you've got to hit the target.

[–] [email protected] 2 points 3 hours ago (1 children)

I'm a little surprised they don't have, like, million-dollar lint, so it'll tend toward the outflow points and clog them.

[–] [email protected] 2 points 3 hours ago (1 children)

Ah, you mean G-lint, we make it from gold flecks because fuck you, oh and it keeps costs high and corrosiveness low.

[–] [email protected] 2 points 3 hours ago (1 children)

Nonreactive, nonmagnetic, high-density, and preeetty.

The ISS has been leaking air for 5 years, and engineers still don’t know why

*raises hand*

Uh, is it the cold unforgiving vacuum of space that forbids our existence there?

[–] [email protected] 4 points 4 hours ago

Space doesn't really have a temperature as you need something to be hot or cold! And in the vacuum there isn't much.

So just unforgiving vacuum.

Fill the ISS with water and you'll be able to see the leak.

[–] [email protected] 2 points 2 hours ago

Just cover the exterior with soapy water

[–] [email protected] 56 points 11 hours ago (1 children)

This is probably the dumbest thing I've heard. You clearly have no idea what you're taking about. To find the leak they need to spray the outside with soapy water. If that doesn't work the next step is to put the ISS in a bathtub and fill the bathtub with water

[–] [email protected] 24 points 11 hours ago (3 children)

Idiot. You obviously have no idea about the logistics of launching a bath into space. You'd need to send a bucket on a rocket (aero dynamic).

Put the ISS into the bucket, fill with water, then squeeze the ISS and look for bubbles.

[–] [email protected] 9 points 8 hours ago (1 children)

Fucking fools. Just use a robotic arm to bend the whole suspect section. You'll see the cracks open up as you flex it back and forth, and can spray some flex seal in the cracks. Seriously, try a little bit.

[–] [email protected] 3 points 3 hours ago (1 children)

Brainless hemroids! Shmear the conspicuous gelatinous substance from front to back, always from front to back. Freshen & powder, and wrap her back up before she starts spewing like a little lad.

[–] [email protected] 2 points 2 hours ago

Great now there's an 1800's sailor on the space station.

[–] [email protected] 5 points 8 hours ago (1 children)

Clearly you're thinking with your feet, because if you used your brain you'd know you bring the ISS to the bathtub, not the other way around

[–] [email protected] 1 points 4 hours ago

Ah, so after the ISS deorbit vehicle dunks it in the South Pacific, we can patch the hole and put it on the ISS reorbit vehicle. Right?

[–] [email protected] 8 points 10 hours ago (1 children)

What a bunch of morons. Just hang some clothes around the ISS and if they wave you've found your leak. No need to send anything because astronauts already have clothes up there ...

[–] [email protected] 7 points 9 hours ago

You all are fools, all this time finding the leak and none of you brought the tire patch

[–] [email protected] 51 points 14 hours ago (1 children)

“The ISS is leaking?? Where?”

“It’s high overhead, orbiting the earth at tremendous speed. But that’s not important right now.”

Yes, it is a space station, and don't call me Shirley.

[–] [email protected] 6 points 10 hours ago

I just wanted to say good luck, and we're all counting on you.

"ISS! More like H-ISS! amirite?!"

[–] [email protected] 7 points 9 hours ago (1 children)

The lack of an H is part of the French contribution to the station.

It's not a leak, it's a leaqu'est

They just need to get their hands on HRAs to keep the hiss at bay. Where's Dr. Darling??

[–] [email protected] 1 points 4 hours ago

Out there looking like dynanite

[–] [email protected] 25 points 15 hours ago (3 children)

Because it’s a slapped-together mess of duct tape and hope?

The ISS is old. It was never meant to last past 2013. At this point, minor malfunctions, like this are expected.

The ISS needs to be replaced with a larger orbital research platform.

[–] [email protected] 2 points 1 hour ago

No it needs to be expanded so that it can house thousands of different species.

[–] [email protected] 2 points 8 hours ago

The ISS is modular

It needs a new module. Undo the tinker toys and put them back together.

[–] shortwavesurfer 2 points 12 hours ago (2 children)

The question is how much would it cost to build such? I believe the International Space Station itself cost like $100 billion to build, which is a lot of money. Now, maybe Space Station construction costs have dropped in the like 20 years, or something like that, since then.

[–] [email protected] 7 points 8 hours ago (1 children)

$100 billion sounds a lot, but in comparison it's miniscule. For that amount of money you can either run an international space station for 24 years or the US military for 1.3 months, or the russian military for one year. If we'd just start killing eachother a little less, we could easily save that much money.

[–] shortwavesurfer 3 points 7 hours ago

I am all for killing less people and funding space stations. That's for sure.

[–] [email protected] 2 points 9 hours ago (1 children)

I would assume inflation made the number bigger today even if costs have dropped.

[–] shortwavesurfer 1 points 7 hours ago

Well, apparently it cost a hundred billion to actually build the thing and that was in like dollars in 2000. So you'd have to hope that space station development went down faster than inflation went up. And if so, it might actually cost a little bit less to build it today.

Question: When Air leaks from the ISS, does it just orbit with it indefinitely as an "air bubble" or maybe a dispersed "air cloud" around it or will it eventually settle down into the atmosphere?

[–] [email protected] 20 points 12 hours ago

In a vacuum, gas will expand indefinitely, so they probably become stray atoms of gas, that will orbit for a little, ocassionallt hitting each other and probably eventually falling back in the atmosphere.

[–] [email protected] 22 points 15 hours ago

Someone needs to close the damn window, we aren't paying to heat the entire universe

[–] [email protected] 11 points 15 hours ago (1 children)

Have they tried lighting a match and following the smoke?

[–] [email protected] 9 points 11 hours ago (1 children)

Hot box the ISS! We need to train stoners to be astronauts so the can come save the day!

Cheesy Aerosmith music intensifies

That's going to need a lot of flex tape.
