- chuckadams 1y ago> Does encasing electronics in lead help against high energy cosmic rays? Makes them worse unless and until you make the shielding several times thicker than anything you'd be able to launch from the ground. Watched one science program that demonstrated it beautifully where the interviewee stuck several balloons on a board and shot at it with a high-powered rifle, popping just one. Then he stuck a metal plate in front of the balloons and shot it, and the resulting shrapnel popped all the balloons behind it. That's a cosmic ray hitting shielding. That's also an unsolved problem with any Mars trip. Electronics can be built redundantly to recover from cosmic ray hits. Humans not so much.
