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?

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.

it was already cancelled and they can return back to normal operations

Imagine something like this happening halfway to Mars and zero chance of escaping, getting any help or parts sent to you.

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.

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.
