NASA Turns Off 2 Voyager Science Instruments to Extend Mission

evidence

Voyager 1's cosmic ray subsystem was switched off on 25 February 2025 and Voyager 2's low-energy charged particle instrument on 24 March 2025; both spacecraft lose about four watts of generator output per year; three science instruments continued to operate on each; Voyager 1's low-energy charged particle instrument was to run through 2025 and be switched off in 2026, and Voyager 2's cosmic ray subsystem was scheduled for shutdown in 2026, with the plan expected to keep at least one instrument running on each spacecraft into the 2030s. V55 verification basis: the release was not fetched — jpl.nasa.gov and science.nasa.gov are both blocked by this session's network egress proxy — but search results carried these specific figures and dates and attributed them to this release.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
