Why do you think so?

JETSON aims to launch a fission reactor that will be started up once in space. The reactor will generate heat, which is then transferred to Stirling power converters to produce electricity. This can then be used to power spacecraft payloads or electric thrusters for propulsion.

I can see launching nuclear payloads being a tough sell politically but the technological principles are sound.

It's also worth noting that past mars solar panels start to be functionally useless, so we use...nuclear powered spacecraft... to generate electricity when needed and have done for half a century. It's not like nuclear stuff in space is a new idea

We even detonated atomic bombs in space
