Space Business Podcast #99 Princeton Satellite Systems: Nuclear Fusion Propulsion Space Business Podcast

Nuclear fusion propulsion. Do I have your attention? Probably ... after all, we need to get to places like Mars, and beyond, faster than on the current chemical rockets. There are now actually some startups working on nuclear fusion propulsion and one of them, Princeton Satellite Systems, are our guests this week. Enjoy!JUST OUT: Raphael's fully revised introductory book on the Space economy, "To Infinity" - https://a.co/d/6jIQ2LO
