Voyager’s structure: How is it made? Pt. 4

Magnetospheric particle analyzer (LEMPA).

Goals:

  • The spectra of the various atomic species comprising the galactic cosmic radiation, especially at low energy.
  • Time variation of galactic cosmic rays.
  • The radial gradient of galactic cosmic rays.
  • Energetic particles of solar origin associated with flares and active regions.
  • Energetic particles of planetary origin.

Magnetometer (MAG)

Although the MAG can detect some of the effects of the solar wind on the outer planets and moons, its primary job is to measure changes in the Sun’s magnetic field with distance and time, to determine if each of the outer planets has a magnetic field, and how the moons and rings of the outer planets interact with those magnetic fields.

Goals:

  • Measure and analytically represent the planetary magnetic fields of Jupiter, Saturn, Uranus, and Neptune.
  • Determine the magnetosphere structure of all the giant planets encountered.
  • Investigate the basic physical mechanisms and processes involved both in interactions between the solar wind and the magentosphere and in internal magnetospheric dynamics, in correlative studies with other particles and fields investigations.
