The space agency said Wednesday that a sensor on Voyager 2 that analyses charged particles and cosmic rays would be turned off later this month. Last Monday, Nasa turned off an experiment on Voyager 1

However, NASA isn’t ready to say goodbye just yet, and is taking measures to get as much life out of the pair as possible. On March 5, Voyager mission engineers at the Jet Propulsion Laboratory in southern California confirmed they have already turned off Voyager 1’s cosmic ray subsystem experiment.

NASA powers down Voyager probes to save power. Instruments shut off to extend life, as the trailblazing spacecraft push the limits of exploration in deep space.
