A 2mm hole has been found in the Russian segment of the ISS after Houston and Moscow noticed minute depressurization. https://blogs.nasa.gov/spacestation/2018/08/30/international-space-station-status/

Quick, break out the duct tape...

Sounds like it might be in the orbital segment of a Soyuz from a post by Chris-B at NSF.

What if someone would try to use finger to block it? :-)

Interesting. I wonder how much effect that little jet is having on the orbit / spin rate....

Probably get a bruise on the vacuum side. Kinda surprised it runs at a full 14.7 psi. 

I wonder what they’re using for sealant? I bet the engineers are itching for a look at the hole, too bad the OM will be jettisoned.

I wonder what would happend if they did that.

Wouldn't it be awesome for your bare skin to be exposed to space? It will probably either burn or freeze.

In reality it's called speed tape isn't it ?

With the amount of area exposed, it wouldn't really matter.

Why would it freeze? Temperature is not transferred in a vacuum.

So they have used epoxy sealant and gauze (and maybe  a toothpick) to replace the temporary tape patch, but the epoxy is bubbling.

 

This seems like the sort of procedure they should test on the ground first.

I am amazed they aren't better prepared for such cases, with ready made plugs and patches ...

Every bicycle rider is, and the pressure difference is 3-10 times as much.

Are there any Dutch engineers aboard?

According former SDC forum user and Shuttle engineer Shuttle_Guy, they call it “space tape”

If I remember right, this has been done several times before, and it's always worked for them. I don't know how you could test a system to repair these holes on the ground, partly because creating a vacuum chamber big enough to test the modules would be very difficult, and partly because microgravity would greatly alter how you would conduct the repair.

Oh, it is transferred. Just very slowly.

Exposed skin would likely expand somewhat due to internal pressure.

As far as I know, it's "irradiated", not exactly "transferred" as we are used to see here, under an atmosphere.

But the outside of the spacecraft is cold with the lack of sunlight.

The ISS's orbital period is around 90 minutes. It spends at least half of that in full sunlight.

The heat energy is transformed into electromagnetic radiation, which then carry the heat away. Transfer is a perfectly fine way of putting it.

Transferring implies in a donor and a receiver. There's no necessarily a receiver on irradiation.

I read that Alexander Gerst did plug the hole with his finger until the Kapton tape could be acquired.

To paraphase, 'Hey, your space station is leaking air, but we didn't think it was worth waking you up about.' :huh:
