Voyager’s structure : How is it made? Pt. 6

Summary

BUS, CRS, High-Gain Antenna, ISS, IRIS, LECP, LEMPA, MAG, Optical Calibration Target, PPS, PLS, PRA, PWS, RTG and UVS…What do these acronyms stand for? Every week (from now till November) I’ll post some components that are part of the Voyager. So stay tuned and let’s get started with PLS, PRA and PWS. Continue reading…

Plasma Science (PLS)

The PLS looks for the lowest-energy particles in plasma. It also has the ability to look for particles moving at particular speeds and, to a limited extent, to determine the direction from which they come.

The Plasma Subsystem studies the properties of very hot ionized gases that exist in interplanetary regions.

One plasma detector points in the direction of the Earth and the other points at a right angle to the first.

Goals:

  • The properties and radial evolution of the solar wind.
  • The interacion of the solar wind with Jupiter, Saturn, Uranus, and Neptune.
  • The sources, properties, and morphology of the magnetospheric plasma from Jupiter, Saturn, Uranus, and Neptune.

Planetary Radio Astronomy (PRA) and Plasma Wave Subsystem (PWS)

Two separate experiments, The Plasma Wave Subsystem and the Planetary Radio Astronomy experiment, share the two long antennas which stretch at right-angles to one another, forming a “V”.
