Default Nuclear-Powered Rockets Get a Second Look for Travel to Mars?

Looks like the British are taking an interest in the concept too:

"Rolls-Royce and the UK Space Agency have signed an agreement to study the
application of nuclear energy in space exploration. The first contract between
the two organizations, the project will examine how nuclear energy can both
power spacecraft and be used for deep-space propulsion.

As humanity becomes more of a spacefaring species, there is a growing need
for power systems and propulsion engines that are closer in scale to their
terrestrial counterparts. There's a limit to what can be done with chemical
rockets and small robotic spacecraft operating in low-Earth orbit, and these
limits are being very rapidly reached."
