If people (politicians, and public) would just get rid of their prejudices and we could just develop a nuclear reactor for outer system exploration and be done with it...
Fuel would not be such a pain to manufacture, there'd be oodles of more power available (more bandwidth for communications, nuclear electric propulsion for faster travel times), and the reactor would be just as safe, if not safer to lift to orbit (unused nuclear fuel is not radioactive, Pu-238 is, although it's so well sealed that it's practically impossible to free it to environment on an accident).
