   Because you said "abundant solar". There is solar power available but   
   I would hardly call it "abundant".

   Yeah, sure it would be possible to cover half of Mars with solar   
   panels and get lots of power but that is not practical nor economical.   
      
   To get the energy of a little 50 MW reactor you need well over a million   
   square meters of solar panels that only work during daylight.
