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…

>but obviously the Russians did no such thing on their side Why obviously? The USSR invited cosmonauts from all over the world to fly and work at the Salut-6, Salit-7 and Mir stations.[0] That's France, Britain, Austria, Japan, India, Soviet block countries, Mongolia, Vietnam, Syria and Afghanistan.

USSR, yes. But the ISS was launching during a time when USSR no longer existed and Russia was fairly isolated. Hence, "obviously": US at that time had many close allies, but Russia had only a few, and not as technologically advanced.

For every complex, difficult and hard problem, there is a simple, easy and wrong solution. Paint obviously is not the right tool for making seals air tight.

Flexseal obviously

You're being sarcastic, but I would like a technical explanation of why this would not work.

Oh, so it's a live blog with updates and a dynamic headline.

It has "Live Updates" in big bold text as one of the first and most prominent lines on the page so... yes? Is that a problem? Publications have had live-updating articles for things ongoing for years. This seems both entirely reasonable and normal, and I'm not sure what the concern or issue is.

I read their comment as a simple “oh ok I understand now” type of clarification, not a complaint.

As of 11 minutes ago, the headline is now the opposite of that submitted: > Astronauts told to return to International Space Station after sheltering over air leak repairs.

We've updated it above. Thanks!

(Submitted title was "Astronauts on ISS told to shelter as repairs under way to fix air leaks", no doubt because that's what the article said at the time.)

Bubble gum? Like do they chew space bubble gum that they could then smoosh in the holes? In college, we'd use toothpaste for the holes left from nails in the walls we hung up our posters with.

Don’t try this if your toothpaste is the blue or green minty flavoured type. You’re welcome.

We actually did this in my freshman dorm room, as the paint color almost exactly matched the original Crest "green".

Is this another potential OceanGate scenario (SpaceGate?), where one day the ISS just blasts apart suddenly and without warning and the occupants are ejected into the vacuum of space?

OceansGate happened because they cut corners.

It is not obvious to me that there is no specialized type of paint that would be appropriate. Doing the whole module sounds like a lot of mass though.

It's hard vacuum on one side. There's a reason the word "hard" is used to describe it.

A few years ago a Soyuz was improperly drilled during manufacture. This was patched with a super epoxy... and then began leaking air on orbit. Paint won't seal what a super aerospace epoxy failed to seal.

I found this interesting: NASA RELL (Robotic External Leak Detector) [1].

    "NASA’s Robotic External Leak Locator (RELL) is a robotic, remote-controlled tool that helps mission operators detect the location of an external leak and rapidly confirm a successful repair. 
    … Two instruments working in sync give RELL its ammonia-detecting superpowers. … Mass spectrometer & Ion vacuum pressure gauge"
