My Dad was the Program Manager for the RTGs that power the two Mariner-Jupiter-Saturn spacecraft (aka, “Voyager”). Even in the 70s, they had to deal with the protesters because of the plutonium fuel. I clearly remember the engineering efforts they expended to make sure the RTGs could survive a launch vehicle crash.
BTW, that sign is hilarious - “NO RADIATION IN SPACE!!”
It’s COSMIC, MAN!
“We jad proteters at the gate for several days many I think was an OWS prototype held up a big sign that said NO RADIATION IN SPACE!!! . I guess he thought the sun was electric.”
Gotta wonder where the heck these people come from.
