109. From Blastoff to Beyond: Ion Thrusters Pushing the Limits of Space Travel

The Next Byte Podcast · 14 Feb 2023 · 22m

What this episode covers

Hosts Daniel and Forbode discuss a University of Michigan study on ultra-efficient plasma thrusters for deep space travel. They analyze how researchers challenged the assumption that ion thrusters have a current cap by running a Hall thruster at five times its rated power, achieving high thrust with water cooling. The episode highlights the switch from expensive Xenon to more affordable Krypton propellant and the potential for scaling these electric propulsion systems to reduce fuel mass for missions to Mars.

    Electric Propulsion with Todd Bailey

    Todd Bailey, who previously worked at Lockheed Martin, Astra, and Apollo Fusion, discusses his journey into electric propulsion and the founding of Starlight Engines, which was recently acquired by Muon Space. He details the engineering challenges of designing a Hall effect thruster that uses solid zinc propellant instead of gas, focusing on the power processing unit and vaporization systems. Bailey reflects on his career transitions, the importance of rigorous requirements-driven design, and the business realities of building flight-ready hardware in the commercial space sector.
