Tangentially: What purpose does ISS serve today? It cost $150 billion to get to this point, but is it doing anything which justifies the operating and maintenance costs?

vs. other uses of the money. On Earth, direct replacement with new in-orbit infrastructure/new station, or other space operations.

> What possible reason would the Russians have to sabotage their own side of their won space craft? Some people believe the Nord pipeline blowup was self-sabotage. Update: I did not say I believe this myself. I'm just using this as a counter argument to say that the reasons might not be obvious at first glance and people tend to believe all sorts of things.

... because it gets them out of contractual obligations to deliver gas.

But… they want to sell gas.

NASA plans to retire the International Space Station by 2031 by crashing it into the Pacific Ocean:

And it's already planning its replacement:

It's there to give the Space Shuttle program a reason to exist.

> is this just usual Russian incompetence? I don't think there is an impression of that or really ever has been. Russia has successfully launched humans into space more regularly and at a lower cost than the US for the last 60 years. (Well until the last few years) I think it's more likely that this is just an occurrence of something akin to the birthday paradox and sometimes things just happen. It's the narrative du…

It wasn’t that long ago they drilled a hole in a Soyuz, then patched it with epoxy and sent it up anyway, only for the epoxy to come out and cause a leak.

As far as I can tell, the evidence for the hole being drilled then epoxied on Earth amounts to nobody wanting to believe the alternative (that it was drilled while in orbit.)

Here is the hole. Personally, I don't see any trace of epoxy in or around this hole: https://upload.wikimedia.org/wikipedia/commons/3/3f/Hole_in_...

(To be clear, it's the small hole, not the big one next to it. The small hole next to the paint marred by a slipping drill bit.)

I say this as a huge space flight enthusiast: I believe the ISS has only symbolic value and serves a secondary function as a subsidy program for component producers. The same was largely true of the Space Shuttle program.

I also don't necessarily have any problems with that, unless it's siphoning away funds that could have been used to build up an actual orbital infrastructure or serves to further the impression that this is the reasonable maximum the public can expect from a human presence in space.

Since the Apollo program we have a history of hinting at, but then purposefully not following through on, the idea of expanding human civilization into space.

Also not that long ago, they tried launching a Proton M which had the angular velocity sensors installed upside down: https://www.russianspaceweb.com/proton_glonass49.html#culpri...

Looks like decades of rampant corruption and political violence are not exactly good for high-tech industry. Who would have thought?

Science? Must every human endeavour generate profit?
