Why Are There Two Different Types Of Electric Space Engines, And How Do They Work?

About

Scott Manley is someone who fell into YouTube because he felt a deep compelling need to teach people orbital mechanics and rocket science so they could play Kerbal Space Program, now, years later the gaming videos are less important and the pure science is the main thrust. My degrees are all in Physics and Astronomy, so much of the rocket science and engineering I've learned is self taught, always learning, always teaching. I used to do this as a hobby, along with my day job in software development, but that recently came to an end and I'm really appreciating everyone who has chosen to support my work through Patreon.
