NASA plans to launch a spacecraft to Titan
A flying drone is a really solid idea for a Titan lander for a couple reasons:* The surface atmosphere density is higher than Earth's (1.5 atm)* Gravitational force is much lower (0.15g)* We don't know a lot about the surface composition or topography, so wheels and motors represent a challenge* Visibility may be poor, making visual navigation tricky (though that's also a problem for a flying vehicle I suppose)I've heard people ask about "why a nuclear power source?" Saturn is 10x as far from the sun as Earth, so sunlight is about 1/100th as bright. In addition, Titan's atmosphere blocks most of that. There really isn't any other realistic option.I hope it works and they take videos.
