View Full Version : Giant Crater Discovered on Titan

SUMMARY: NASA's Cassini spacecraft spotted a large impact crater on Titan during its flyby on Tuesday. The crater is 440 km (273 miles) wide, and has unusual parallel lines on it (researchers have nicknamed them "cat scratches"). It's believed that these lines could have been formed by winds, like sand dunes on Earth or Mars, but it's also possible that another geological process is at work.

Perhaps liquid methane and ethane on titan are erroding the crater.

It no longer looks like there are lakes of oceans of liquified gasses on Titan, except perhaps under the surface. The crater might have been eroded by Methane rain in the pst, but now, who knows. Perhaps Cassini will observe some things in the next five years that will tell us, but more likely we'll have to wait for a Titan blimp probe to really study the atmopheric processes on that moon.

They look like ridges on the surface. Very odd indeed.
