> After multiple inspections and sealant applications, Nasa reported in January that pressure readings suggested a stable configuration had been reached - though there remained uncertainty about whether the leak had truly been sealed or whether air was simply escaping elsewhere.

I'm clearly not understanding what they're trying to say here. If _one_ leak was sealed, but the air was "escaping elsewhere", it would still be a leak, causing pressure readings to drop.

I read it as an inability to measure the leak rate immediately after the repair. If the rate is slow, measuring it takes time.

It's an almost 30 year old nearly 500 ton structure subjected to radiation, bombardment by starstuff and debris, the stresses of docking and undocking, of boosts, and of constant heating and cooling as it passes in and out of the sun. Getting a clear picture of the comings and going of gasses is probably not easy.

Also in 2021, Nauka (the cursed Russian module) arrived on the station, and accidentally fired thrusters while attached, fighting against the attitude control of the station, flipping it around 540 degrees and putting a lot of stress that the station wasn't designed for on all the structural parts.

I'm proud of us that multiple nations can coordinate such a complicated project for so long.

Somehow I never heard about that. Do you know of a good article that goes into detail about it?

Thanks

This is a decent overview:

It was surreal to follow when it was happening, NASA was seriously underplaying what was going on and it was up to amateurs with telescopes looking at the station to tell the world that the situation is still ongoing.

This is one of the three major mishaps related to Nauka.

Take away the mass figure, and it happens to all of us eventually ;-)

Are there things that happen on board that increase the pressure - eg fermentation whether it’s experiment or in humans?

[lostfiddler]

Humans can ferment?

[Kye]

That's where farts come from.

It could be that the instruments were looking at the differential pressure. E.g. the pressure in that section compared to another. A leak elsewhere would throw off the comparison.

Air was no longer escaping at the local point of repair.
