I wonder what the costs would be to just literally launch it into the sun. Let it all get recompiled in the big fusion furnace and out of our hands. Of course if the rocket failed during launch you have a real big problem, but that part aside.
Not sure anyone would sign off on sending potential dirty bombs into space.
At least not anymore.... We did a successful test of a nuclear powered ramjet in the 60's with project Neptune. But I guess that was before people were afraid of dirty bombs welded into the shape of cruise missiles.
There was also a plan to explode nuclear bombs on shorelines to create artificial harbors, and of course the infamous Project Orion, a manned interstellar spaceship powered by exploding hydrogen bombs. Doing unhinged shit with nukes was all the rage back then I guess
Even if we had a magic 100% reliable rocket it still wouldn't be a good idea to send it into space. You'd have to have a stupidly powerful magic 100% reliable rocket to get into a solar intercept orbit, otherwise it would just hang around the Earth for a very long time and eventually come back down as nuclear fire dust.
It's not as if storing it underground is an unsafe strategy so it seems like a pointless exercise.
Thus the 'aside from launch failure's part. No rocket scientist here, but way I figure if we can send probes to do flyby photos of the outer planets how hard can it be to hit the biggest thing in our system?
Lift costs might be stupidly high too, but more a would it be possible thought.
Because the other planets are in orbit of the sun like the Earth is. The sun itself is stationary, so not only do you have to go all the way over there, you also have to cancel out the rotation of the Earth.
