Video description excerpt:

In November 2023 Voyager 1 stopped communicating with Earth, the telemetry it was sending contained no information, but engineers working on the spacecraft could tell it was still listening. It would take months of experimenting to understand the problem and develop a fix using techniques that had never been employed before and designing software for a 50 year old computer using pen and paper.

Very interesting video, especially seeing some of the assembler code examples, etc.

Wasn't there an earlier error where they basically disabled one broken bit in RAM? I think that was at least a decade ago.
