Scientists ponder how to get samples from Saturn's weird moon Titan


"Science begets knowledge, opinion ignorance.
Saturn's moon Titan is a mysterious world. The second largest moon in the solar system, Titan is larger than the planet Mercury and, next to Earth, is the only place in the solar system with flowing rivers of liquid and lakes on the surface. Except these rivers and lakes hold not water but hydrocarbons, such as methane. But Titan also has water — an entire ocean of it, under the moon's frozen surface. Titan also has an atmosphere rich in nitrogen, just like our planet.
