NASA plans to launch a spacecraft to Titan
A flying drone is a really solid idea for a Titan lander for a couple reasons:<p>* The surface atmosphere density is higher than Earth's (1.5 atm)<p>* Gravitational force is much lower (0.15g)<p>* We don't know a lot about the surface composition or topography, so wheels and motors represent a challenge<p>* Visibility may be poor, making visual navigation tricky (though that's also a problem for a flying vehicle I suppose)<p>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.<p>I hope it works and they take videos.
