Cosmic Ray Subsystem (CRS)
technology
The particle telescope that measures energetic charged particles — galactic cosmic rays arriving from outside the heliosphere and anomalous cosmic rays produced within it. Its readings are one of the two signatures that identify a heliopause crossing: as the spacecraft leaves the Sun's bubble, the anomalous component drops away and the galactic component rises sharply. The instrument was switched off on Voyager 1 on 25 February 2025 to save power. On Voyager 2 it was still running in August 2026, and was one of the instruments whose shutdown the July 2026 power manoeuvre deferred. Not a place.
A technology is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
