Are you sure? The main reason it takes so long to get to Mars is, that the probes aren't under full thrust the whole time. Because fuel would be needed, which in turn would need to be accelerated at first which needs more fuel to accelerate all the fuel. I don't see how nuclear propellants solve that problem. If I look here, I see the proposed nuclear rocket engines, they are hypothetical: https://en.wikipedia.org/wiki/Rocket_engine#Nuclear |
Go to Wikipedia and look at a Gas Core Nuclear Rocket (GCNR)
