NASA engineers are turning off two instruments to ensure that the twin spacecraft, Voyager 1 and Voyager 2, can continue exploring space beyond the limits of the solar system.
To save energy for further interstellar exploration, mission engineers at NASA’s Jet Propulsion Laboratory (JPL) deactivated Voyager 1's cosmic ray subsystem experiment on Feb. 25. On March 24, they will shut down the low-energy charged particle instrument onboard Voyager 2.
