actually a pretty cool story for my nerds out there. they never really lost contact with it.
one of the chips finally failed (remember it was made in the 70s). the chip was responsible for packaging up the health and science data. they remotely updated the firmware with the code from the failed chip, but since they're so limited in memory they had to spread it over a bunch of other chips.
so they inserted jmp instructions for a custom dynamic linking scheme, on the fly, from like 20 light-hours away, across other running chips..and pulled it off without segfaulting the damn thing
impressive as hell to be honest

Yeah but NASA is full of DEI idiots that believe in manmade climate change.

Yeah, that's what I would have done.
