As the Psyche mission begins its journey in late summer 2022 out to the asteroid belt, it will first be aboard a SpaceX Falcon Heavy launch vehicle, then make its own way out into the solar system using a solar electric propulsion system and a gravitational assist from Mars to reach the asteroid belt, specifically to the Psyche asteroid, in order to determine whether Psyche (the asteroid) is remnant core material from a planetesimal, how old it is, whether it formed in similar ways to the Earth’s core, and what its surface is like.
Where our project comes in is the visualization of hollow cathodes, a piece of technology used in a variety of industrial applications, as they are used in the Hall thrusters aboard the Psyche spacecraft. Our goal is to help educate the general public as to how hollow cathodes function as a part of the onboard thrusters and make it easy for anyone to understand how this simple piece of technology can ensure the success of the Psyche Mission.
The deliverables we developed as a part of this project were a Unity WebGL build comprised of a 2D animation of the process, and a site (linked below) to host the visualization on.
