Video Description

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.
