   All three of those are more abundant for nuke work on Earth.   
   Space is a deadly place that could kill you if you don't handle it   
   properly.  Even more so than plutonium.   
   Asteroids are even rarer on Earth than Uranium, which can be extracted   
   from seawater at about four times the current cost.   
   The knowledge to run an extended space mission, including installing a   
   nuclear propulsion drive onto an asteroid, is orders of magnitude   
   beyond using those nuke explosives on Earth.

   We are geeks.  Resistance is voltage over current.
