NASA Jet Propulsion Laboratory is using one of our 20 foot Outdoor Radio-Controlled Blimp powered by electric motors to test the feasibility of using blimps to explore the surface of planets and their moons as shown in this illustration of Saturn's moon Titan

We also supplied NASA with a 7.5 ft (2.3m) Trade Show Blimps for the same project with autonomous control provided by Micro Pilot shown here with the blimp.
