View Full Version : Liquid Methane Drizzles Down on Titan

New research from NASA, published in the journal <i>Nature</i> suggests that it's always raining on Titan. Not thunderstorms, but a low level liquid methane drizzle that never stops. When Huygens landed onto the surface of Titan, it came down with a splat, presumably into mud. Scientists estimate that the amount of rain amounts to about 5 cm (2 inches) a year of accumulation - the same amount that falls in Death Valley on Earth. But this rain falls steadily, keeping the ground relatively damp.

Well...This dribbling rain and mud flat is more consistent with the Huygens' accelerometer and GCMS data, but it makes it a little difficult to explain the extensive sand dunes.

Other theorists have interpreted the 'wide channels' observed by Huygens as evidence of spotty, once in a blue moon storms, similar to the topography of Arizona.

It's a good puzzle.

How about rain due to temperature drops during eclipses of the Sun as seen from Titan by Saturn?

But the dunes? Any ideas?
