According to Guinness, the top is Voyager 2:
> The computer system that has been in continual operation for the longest period is the Computer Command System (CCS) onboard NASA's Voyager 2 spacecraft. This pair of interlinked computers have been in operation since the spacecraft's launch on 20 August 1977. As of 29 October 2020, the CCS has been running for 43 years 70 days.
