NASA-backed aerobots could explore caves on Saturn's moon Titan

Nasa is backing a new concept for small flying robots to explore caves on Saturn's moon Titan. These proposed vehicles, called aerobots, would use silent electrohydrodynamic thrusters for movement. Titan's dense atmosphere could make this propulsion system highly efficient and practical for exploration. The SPARK project is currently in an early research phase, focusing on feasibility studies. This technology could significantly expand future exploration of Titan's hidden underground environments.
