Crater Lake on Titan

This artist's rendering shows Titan's surface with Saturn dimly visible in the background through Titan's thick atmosphere of methane, ethane and (mostly) nitrogen. The Cassini spacecraft flies over the surface with its high-gain antenna pointed at the Huygens probe as it reaches the surface. Thin methane clouds dot the horizon and a narrow methane spring, or "methanefall," flows from the cliff and drifts mostly into vapor. Smooth ice features rise out of the methane/ethane lake, and crater walls can be seen far in the distance. By David Seal. (P-46508AC)
