Nuclear propulsion is more efficient but doesn’t produce enough thrust for surface launch(\) We are stuck with chemical rockets for that. Nuclear could help us get to Mars faster or launch less mass from the surface. It may even be relevant for the upper stage of a launcher. But not for getting off the ground. (\) with the notable exception of Orion |

When we finally do it, that's probably how it'll happen.
