@BowsacNoodle @Professor_Groyper That was the incredible part on what they did! The team didn’t know if it would work but made the risky decision. I think it was something to do with preventing some type of accumulation of something from its fuel system. Imagine doing a remote software patch on a computer built with 68K tape decks for memory devices & runs FORTRAN. Add a 48 hour deep space data transmission speed. They were in a crisis not too long ago maybe 5 years? The guy that operated the Voyagers for years retired and was the ONLY one at NASA who knew how to run FORTRAN. They couldn’t even find Voyagers’ original manual.
