As humanity’s furthest reach into the Universe so far, the two Voyager spacecraft’s well-being is of utmost importance to many. Although we know that there will be an end to any science…
There are currently five science investigation teams participating in the VIM. The science teams for these investigations are currently collecting and evaluating data on the strength and orientation of the Sun’s magnetic field; the composition, direction and energy spectra of the solar wind particles and interstellar cosmic rays; the strength of radio emissions that are thought to be originating at the heliopause, beyond which is interstellar space; and the distribution of hydrogen within the outer heliosphere.
There are 4 operating instruments on-board the Voyager 1 spacecraft. These instruments directly support the five science investigations teams. The Planetary Radio Astronomy Investigation (PRA) is no longer working on the Voyager 1 spacecraft and the Ultraviolet Spectrometer Subsystem (UVS) is no longer working on Voyager 1 or Voyager 2.
