Silent ion-powered robot swarms could map subsurface caves on Saturn’s moon Titan
SMRTR summary
NASA is funding SPARK, a project developing swarms of tiny, ion-powered spherical robots to explore the underground caves of Titan, Saturn's largest moon. Using electrohydrodynamic propulsion with no moving parts, these aerobots would be over 100 times more power-efficient on Titan than on Earth. The project begins a nine-month feasibility study, with a possible connection to the Dragonfly mission launching in 2028.
