NASA Backs 9-Month SPARK Study for Titan Drones, With 100x Ion-Flight Efficiency

Summary
A 9-month NIAC Phase 1 grant will fund SPARK feasibility work on tiny spherical aerobots designed to fly through Titan’s caves, sinkholes and karst terrain that rovers cannot reach.
NASA says electrohydrodynamic thrusters could be more than 100 times as power-efficient on Titan as on Earth, while their solid-state design avoids moving parts that could freeze or jam in extreme cold.
Daniel Drew’s team at the University of Hawaii, JPL and the Blue Marble Space Institute will model Titan-like performance, run thermal tests and study tethered-power balloon station-keeping before defining a Phase 2 prototype.
A flight mission remains distant: SPARK is only at the start of Phase 1 and would still need a 2-year Phase 2 evaluation, while NASA’s Dragonfly Titan rotorcraft is currently targeted for a 2028 launch.
