  • In some ways it kinda helps, the larger physical structures of the older computer hardware make it naturally more resistant to cosmic radiation than new stuff. New stuff just needs more shielding though, so not a huge deal.

    But a big part of it staying viable for this long is that it was designed in a way that made it possible. Alot of forethought went into making sure it would last as long as possible. While they didn’t expect it to for sure last this long, they did at least want to make sure the reason it didn’t wasn’t because they didn’t plan for the possibility. There was a decent element of luck too, as there were more unknowns back then about what it was going to be subjected to on its journey.

    The whole way the onboard computer functions was optimized for remote repair though, because of course the plan was to never see it again, and they knew it was going to need to be repaired alot despite. So at any point in it’s “thought process” it is waiting to be interrupted by a call from earth telling it to stop all that and basically dump the entire contents of it’s operating memory. And can recieve an entire rewrite of it too, with built-in checks to make sure it recieved it right before starting to operate from it again. Luckily an entire rewrite of everything it can possibly hold is 70kb. So despite the distance and chance of failure, it’s still not that bad of an ordeal.
