ТhoughVoyager 1 is old, it should be able to keep traveling for a while longer, provided nothing too important breaks down. The probe's declining power supply won't force engineers to shut off the first instrument until 2020, mission scientists have said. All of Voyager 1's science gear will probably stop working by 2025.
