Are there any courses / tutorials / books on the engineering of this system? I'd love to know what kind of choices you make with software when your system needs to run for decades and be remote debuggable at the lowest levels.

Clever fix, very smart that the system supports this degree of remote patching.

Does anyone with more context know how are they rearranging the memory bits mentioned in the article. Are they patching this using malloc/realloc or is it something entirely different?

Latency aside, what's the baud rate of Voyager 1?

47 years. It's been out there 47 years. It's awe inspiring that a) it's still operating, and b) some wicked smart folks in JPL can reconfigure its code remotely to get it back on its feet. A huge achievement for no other reason than it just is. Congratulations to the smarty's.
