I really detest Musk but Dragon has had a really good track record.

Falcon 9 is also the most successful vehicle ever flown. The modern zeitgeist of not liking someone in one area so now everything associated with them must be bad is insufferable.

>Falcon 9 is also the most successful vehicle ever flown.

I feel like thats due to the sheer number of launches, which turns out are mostly paid out of pocket, as Space X is hugely unprofitable.

Thats not to say its not a good design, the Falcon engine is actually well made because of the open cycle design which is MUCH simpler to control than the Raptor which is the equivalent of Twin Turbos + Nitrous on 2.0L 4 banger pushing 1000 hp.

Can't they just get things out of the module and paint it fresh? Maybe with some special paint, or with several layers of a paint? Obviously they can't, it looks like an obvious solution they couldn't have missed. But I wonder why it is impossible to do.

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.

Obviously you need to use air tight paint.

Is there any rocket-builder without a history of blowing things up?

I feel like other rocket builders, whether private or government, have way less launches but they have more successful launches percentage wise than Space X.

They just didn't have enough of reserved general purpose connections for future use. I guess this woild be especially the case with the Russian modules, which were literally surplus Soviet manned space army outposts(such a thing do not make a lot of sense, they did it anyway).

This one https://en.wikipedia.org/wiki/Salyut_3 had a machine gun!

What was the gun for?

I’m imagining a pool snail

One thing that’s rarely discussed about spaceflight is that for the foreseeable future, it will have to happen without the animals that humans rely upon on Earth. I think this will expose just how strong that reliance is in some areas.

I wonder about what happens to gut micro biomes

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?

There are of course potential failures, but not quite as violent as oceans gate. There is 1 atm of pressure difference between the inside and outside of the ISS. At titanic depths the pressure difference between inside and outside of the submarine was approximately 400 atm. Thats why the ISS can have small leaks like this that are a problem but not catastrophic like they would be in a deep sea submarine.

There is 1 atm of pressure difference between the inside and outside of the ISS.

For comparison, a can of soda has around 2-3 atm depending on its temperature.

I remember reading about the ISS in the May 1998 issue of Popular Science, a full issue about the station. They were getting ready to launch the first module. Every time bad news happens, I think about this part (from a PDF I hang on to): >> "SOMEDAY, THE international Space Station will descend, but if you're frightened at the prospect of a million-pound hunk of metal falling out of the sky, take heart. NASA does ha…

This never happened though, and as a result the ISS stayed up for longer. SpaceX is now the group that will deorbit it, as one big chunk

Why did you feel the need to post this comment?

Why post anything online? Im getting the sense that you are here to defend Space X and Elon Musk on the battlefield of internet forums.

I certainly am not. The only positive thing I have to say about those two is that SpaceX has cool rocketry tech.

>Why post anything online?

Typically people post things on HN for different reasons than they do on reddit or bsky, but your post seems like a much better fit for reddit or bsky. These types of factually nonsensical ideological signaling posts are popular on those websites, but are generally considered to be in poor form on this website.

>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. [0] https://en.wikipedia.org/wiki/Interkosmos

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.

>Russia was fairly isolated

Quite the opposite, the West welcomed weak and crumbling Russia. To a limited extend, of course, but still Russia joined G7 and many European organizations. Western companies were busy buying privatized Soviet assets pennies on the dollar.
