We won't even put the stuff in a cave in a desert that will be stable for the next 10,000 years with probability of .999999. Rockets? Those things blow up quite regularly and spread their debris over vast tracts of land. Also, radioactive waste is about as dense and heavy a payload as you could possibly imagine. Just mine the asteroids, they require lower delta V than Mars (yay no gravity well) and there are, as demonstrated by this site, better economic incentives to do so.
