The Voyager probes are each turning off an instrument to avoid ending their 47-year-long missions later this year.

NASA is switching off two science instruments on its twin Voyager spacecraft to save power. The space agency said Wednesday an instrument on Voyager 2 that measures charged particles and cosmic rays will shut off later this month.

Mission engineers at NASA's Jet Propulsion Laboratory in Southern California turned off the cosmic ray subsystem experiment aboard Voyager 1 on Feb. 25 and will shut off Voyager 2's low-energy charged particle instrument on March 24.

Engineers at NASA's Jet Propulsion Laboratory have conserved energy supplies on the record-setting Voyager 1 & 2 deep space probes nearly 50 years after their missions launched to extend them further.

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.
