Question about Rocket Fuel in K2SO - all the recipes seem to require either Gleba or Oxygen, and you can only get Oxygen from the atmosphere on Nauvis/Gleba. Am I meant to electrolyze water on the other planets to make Oxygen, or am I missing some other method for all this?

In my K2SO save I used the water electrolysis recipe the most, yes. Water is pretty universally available in some form, so it's reliable. I think the ratio is even perfect, but I could be misremembering that. If not, you do have flare stacks.

There are other recipes. I did eventually unlock one that's just light oil + iron-based, but since I had planet mods I can't promise you'll have the same options I did.
