Why Hacker News recommends it

HN recommends it as a rare look inside a rocket factory and cites it for manufacturing details like welding methods.

What it is

Destin Sandlin tours United Launch Alliance's rocket factory with CEO Tory Bruno, showing friction stir welding, structural rocket skins and large milled parts.

A lot of rocketry advancement would not be happening if SpaceX didn't enter as a competitor. For that reason alone SpaceX should be lauded. It helps that SpaceX is pursuing the dream of a space faring civilization that was promised decades ago. Relativity Space looks cool. But until they launch they will sit in the stack of neat tech to maybe be excited about. I am excited by humans doing things to advance the species. I don't care much who is doing it. But, I have been burned by too much vaporware to get excited by marketing pieces. If you haven't watched Smarter Every Day's ULA factory tour I highly recommend it. There is even a nice bit about how their materials have improved as computers

Smarter Every Day has a very interesting video[1] inside the factory of United Launch Alliance in which, among a lot of other things, shows the friction stir welding used in their Atlas Rocket[2]: [1] [this video] [2] [this video]

It's so cool to get a tour like this, fascinating stuff. The part at 13:30 seems to be some really valuable knowledge, when he says: if you are not occasionally adding things back in, it means that you are not eliminating stuff aggressively enough. Smarter Everyday did a tour of the ULA facilities [0], which is also worth checking out if you like this kind of thing. [0]: [this video]

In fairness, ULA has done that too. [this video] Also literally everything Destin/SmarterEveryDay puts online is worth watching.

There’s a great “Smarter Every Day” video on how rockets are made and the guest host was Tory Bruno. [this video] Two things I recall from this video from years ago 1. Tory really seemed to be a true expert. Not a typical “CEO”. 2. Seems like a genuinely nice guy, see this moment when Tory recognized Dustin’s dad [LINK]

> Ideally you would use a turntable to rotate the cylinder while welding the sections together with a sub-arc machine. [LINK] Uh, at least in the video that steel is pretty thick. Starships skin is slightly less than 4mm thick... while in that video they have a 2cm deep groove, would the same technique actually work? For what it's worth, ULA stainless steel (<1mm thickness) upper stages are resistance welded instead [this video] That said, I think a lot of the decisions right now are based on "what can we quickly experiment with" not "what is a good long term plan". Building a 9m turntable (diameter of the rocket) would take a long time.

Doing a model rocket would be tougher there's a lot of bits they just couldn't show him due to ITAR restrictions. Also beyond the engines rockets are a LOT of empty space, there is some interesting structure in the skin but most of the volume is just empty. Destin from Smarter Every Day did a tour of the ULA factory where you can see the skin that provides a lot of the structure for their rockets. [this video]

I'm far from an expert but it seems like at least some companies use cnc milling very extensively which I can't imagine is all that fast either. Many of the huge parts in this SmarterEveryDay video at ULA have tool markings e.g. at 8:40. I'm also skeptical of 3d printing being as big of a boon as they pitch but I also wouldn't be super surprised if it nets an improvement in speed for some parts. [this video]
