Only one spacecraft has ever returned photographs from the surface of Titan, Saturn’s mysterious gas-covered moon. Titan doesn’t make it easy though, below its clouds is a frigid surface where mountains are made of water ice frozen harder than granite.
Titan is also the only other world in the solar system where liquid flows across its landscape. But this is not water as we know it, instead, liquid methane creates vast seas, lakes and rivers. The European Space Agency’s, Huygens probe is the only spacecraft to ever land on Titan, and what it observed is truly incredible.
Here are the only photos we have from the surface of Titan.
