This device is also interested in analyzing the magnetospheres of the planets. Specifically, it also collected data about the physics of the magnetospheres, as well as the density of the electrons within it. It was able to use this data to compare the magnetospheres of Jupiter and Saturn. It also collected data on wave-particle interaction. Scientists currently believe that light is both a wave and a particle, a concept that has yet to be fully understood, which is why data of this variety is a valuable collection. Both plasma wave systems are still collecting data, although the system on Voyager 2 has been partially disabled.
The third-to-last device on the probes is the radio science system. Using radio waves, this device was able to obtain information about the make-up of the planets and other space objects, including their mass, densities, gravitational fields, and atmospheric composition. This was also useful in determining the size and distance of Saturn’s rings and the objects that compose them. Neither radio science system is still collecting
