NASA Funds Spherical Flying Robots to Explore Caves on Saturn's Moon Titan
NASA is backing SPARK with up to $175,000 to test silent, lighter-than-air aerobots that could reach Titan’s caves.
- NASA awarded an Innovative Advanced Concepts grant to the SPARK project, led by University of Hawaii assistant professor Daniel Drew, to develop spherical aerobots for exploring caves on Saturn's moon Titan.
- Titan's surface is covered in 'karst' terrain featuring sinkholes and subterranean channels that are difficult for traditional land rovers to traverse, making silent flying aerobots a potential solution for scientific exploration.
- Electrohydrodynamic thrusters power these aerobots, projected to be over 100 times more efficient on Titan than on Earth, offering maneuverability without the heavy downwash caused by traditional rotorcraft propellers.
- The project received $3.2 million in NASA funding to begin a nine-month Phase 1 feasibility study; Drew noted the aerobots must complete a two-year Phase 2 evaluation before flight becomes realistic.
- Whether SPARK can join NASA's Dragonfly mission, targeted for a 2028 launch, remains unclear; however, Drew hopes the aerobots will eventually serve as cave-exploration scouts similar to the Ingenuity helicopter on Mars.

Under the surface of the Titan moon, one of the most fascinating worlds in our solar system, lies a vast underground network of caves and dolphins that has remained unexplored. Now, an ambitious concept proposes to send spherical flying robots, easier than the air, in these underground channels, reports Gizmodo. NASA finances the project through its program...
NASA funds ion-powered flying drones to explore Saturn's largest moon
NASA is funding an ambitious new concept that could send swarms of tiny, silent, spherical “aerobots” floating through the eerie underground caves of Titan, Saturn’s largest moon. The project is called SPARK or Solid-state Propulsion for Autonomous Reconnaissance of Karst. Led by Daniel Drew, an assistant professor at the University of Hawaii at Mānoa, SPARK uses electrohydrodynamic (EHD) propulsion, commonly known as atmospheric ion thrusters…
Mission SPARK: Will tiny aerobots explore Saturn’s largest moon, "Titan"? Here’s what NASA has planned
NASA has funded an early-stage concept for spherical flying robots that could explore the hidden caves of Saturn’s moon Titan. Called SPARK Aerobots, the vehicles would use near-silent ion propulsion to navigate difficult underground terrain.
