I had a rather strange curiosity today. How do fuel pumps on rockets work? I imagine that the use of pressured gas would be a good way to enable that (same as how F1 cars are fueled). It appears that turbo pumps also have to struggle with temperature and pressure differences in the extremities of space. And I can’t even imagine how a solid fuel engine works.

I wish there existed some better video content on how something like that works though!
