As someone who has done rad hard fpga design as well as radiation testing of components, I can say: that's too bad. Rad hard parts are so behind commercial, and have such high unit costs (RTG4 is ~90k each, 300krad TID), and the verification is grueling. It's fun to see your stuff leave the planet, though.
