I was wondering if I could process fuel out of Saturn's atmosphere? I'm thinking not of liquid hydrogen, which is useless to my chemical rockets, because of lack of LOX. I'm staying away from nuclear thermal rockets for this, so it has to be a chemical rocket (about the size of a Delta II.) Could I manufacture hydrazine? Would a Delta II sized rocket get into orbit just on hydrazine??

Formula N2H4

There are trace amounts of ammonia in the atmosphere, but I'm thinking it would take forever to extract enough ammonia, process it and fill a Delta II tank....

Many back to the drawing board?

Even if one could produce hydrazine from Saturn's atmosphere, which in my
view is highly unlikely, one would still need an oxidizing agent like for exam-
ple dinitrogen tetroxide or nitric acid to use the hydrazine as rocket fuel.

I did suspect it was a no go, oh well ... I'll develop my floating drone with a nuclear thermal rocket then, using Liquid Hydrogen that it can extract.... Thanks rust...

It would probably be easier to extract what you need from the moons of Saturn rather than from the gas giant itself. The energy to lift your fuel into space is going to be a LOT less (even from Titan) than skimming the gas giant.

Break water into Hydrogen and Oxygen and use that! Solar power is probably too weak, but perhaps a nuclear reactor to break the water. Rhea might be your best location for a fueling station. Smaller then Titan and has plenty of water, it might have a trace of an atmosphere and probably has liquid under the surface (maybe).
