If you're interested in space propulsion systems, check out the Technical Projects section of the British Interplanetary Society (est 1933). Noteworthy was their Project Daedalus, a 1970s vision of an interstellar mission accelerated to sub-light speed, by a chain of small nuclear detonations. Yes, bombs in space...
