Space Science And Technology Tames Grid 60% vs Ion
5% of the grid area once thought necessary now powers Phobos-3’s plasma wake thruster, proving city-sized structures are unnecessary. The Phobos-3 demonstration used a deployable metal patch under 50 cm² and delivered stable thrust, reshaping expectations for deep-space propulsion. You’ve been told plasma thrusters need a city-sized grid
