A World Where it Rains Liquid Methane

Possibly the most exciting space missions ever to have flow was the Huygens probe that landed on Saturn’s moon Titan. On Titan it is so cold that liquid methane takes the place of water, flowing in rivers and raining from the sky. The surface is startlingly earth-like, despite the fact that the “rocks” are water ice.
The landing took place in January 14th of 2005 in the region of Xanadu.
