There are three computer systems on each Voyager. They are dedicated to specific tasks (Flight Control System, Attitude and Articulation Control System, and Computer Command Subsystem), each with two instances for redundancy.
- scottLobster 6y agoRight, but that redundancy to my understanding is in case of component/system failure. It's a backup, not a judge-actor or error-correcting architecture. Case in point: https://www.jpl.nasa.gov/news/engineers-diagnosing-voyager-2-data-system-update https://www.jpl.nasa.gov/news/engineers-diagnosing-voyager-2... "Engineers successfully reset a computer onboard Voyager 2 that caused an unexpected data pattern shift, and the spacecraft resumed sending properly formatted science data back to Earth on Sunday, May 23. Mission managers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., had been operating the spacecraft in engineering mode since May 6. They took this action as they traced the source of the pattern shift to the flip of a single bit in the flight data system computer that packages data to transmit back to Earth. In the next week, engineers will be checking the science data with Voyager team scientists to make sure instruments onboard the spacecraft are processing data correctly. "
