I'm writing a sci-fi novel in German, as I'm German myself, but since I usually only read (and watch) English sci-fi, I'm stuck on some terms that I can't think of a German word for.
In the current scene I'm writing, a space marine is navigating space in a space suit. The suit doesn't have an engine, it only has an array of small navigational thrusters. In English, I'd write something along the lines of "He engaged his thrusters to catch up to Bob."
Another use would be on the space ship, like the Star Trek Enterprise docking to some starbase and Picard saying "Thrusters only, Ensign Crusher."
I've found some words I could use, e.g. Schubdüsen, but they don't feel right. Especially Navigationsschubdüsen gives me a headache just from reading it. It might just be my lack of familiarity with German sci-fi terms, though.
