"Onboard are four science experiments: Fields Experiment, which studies electric and magnetic fields; Integrated Science Investigation of the Sun, which measures high-energy charged (which means electric) particles in the solar wind and corona; Wide-Field Imager for Solar Probe, which images the solar wind and other structures; and Solar Wind Electrons Alphas and Protons Investigation, which measures different types of (electric) particles in the solar wind. "
NASA finally took a dramatic step in trying to elevate itself from the entrenchment the astrophysical community has been mired in for the past 100 years due to Eddington's horse-and-buggy era theory of stars by building a probe that is 100% aimed at understanding the electrodynamics of stars.
Between the data that this probe is sending to us, combined with the information that Voyager 1 and Voyager 2 are sending back regarding the double-layer boundary at the edge of the heliosphere, all that will be left will be for someone at NASA to put 2 and 2 together to realize that all three probes are reporting the same thing: the electromagnetic physiology of our star, and how very, very much larger and more beautifully complex it is than Eddington could have ever envisioned in his lifetime.
Welcome, one and all, to our amazing Electric Universe!
