Episode Details

Dr. David Kipping joins John Michael Godier to unpack T.A.R.S., a solar-powered, spin-driven sail that leverages radiometer-like physics and a spinning dipole to accelerate lightweight probes and generate magnetic fields. They also explore relay networks for deep-space communications, science in the interstellar medium, and a bold Jupiter “atmospheric lens” concept to boost signals—plus implications for Mars shielding, mission cost–benefit, and the search for technosignatures.Links: A New Interstellar Propulsion Method: T.A.R.S.https://youtu.be/MDM1COWJ2Hc?si=Kw5SYtvEA441nMKaTorqued Accelerator using Radiation from the Sun (TARS) for Interstellar Payloadshttps://arxiv.org/abs/2507.17615@CoolWorldsLabSupport the Cool Worlds Lab and it's research: https://www.coolworldslab.com/supportYouTube Membership: https://www.youtube.com/channel/UCz3qvETKooktNgCvvheuQDw/joinPodcast: hhttps://creators.spotify.com/pod/show/john-michael-godier/subscribeApple: https://apple.co/3CS7rjTCHAPTERS00:00 Intro — welcome & setup00:32 Kipping’s bio, Cool Worlds & research focus02:03 T.A.R.S. — radiometer-inspired interstellar concept04:11 Why classic solar sails stall with distance06:02 Sub-Keplerian “quasite” orbits explained07:04 Could T.A.R.S. shield Mars with a magnetic field?10:46 Simplicity & cost: why swarms are attractive16:46 Deployment, micro-thrusters, initial spin-up17:21 Gyroscopic stability; dissipating energy via cyclotron radiation18:27 Why the odd shape?
