It was my understanding that you could make a nuclear powered spaceship without needing liquid fuel. Whenever I use thermal thrusters, they require liquid fuel. Whatever I do. And plasma thrusters don't propel, even in space. What do I do?? I don't use antimatter reactors though, as they are hard to find fuel for. Whenever I try to use the toggle propellant on the thermal thrusters, it just stays on liquid. Is there any way to run without liquid fuel? Just nuclear?
