A fascinating feature recently discovered on the surface of Mars, of unclear origin. Water-bearing channels are visible on the images, as shown below:
 



www.cnn.com
The Medusa Fossae formation is an extensive area of unknown origin found near a boundary between the highlands and lowlands of Mars. It straddles the Tharsis and Elysium centers of volcanic activity.

This dichotomy boundary is a narrow region separating the cratered highlands, located mostly in the southern hemisphere of the red planet, from the northern hemisphere's lowland plains.

The cratered highlands stand 1.2 -- 3.1 miles (2 -- 5 kilometers) above the lowland plains, so the boundary is a relatively steep slope.

The processes that created and modified the boundary remain a major unanswered issues in Mars science, say scientists with the European Space Agency, which released the Mars Express orbiter images last week.

I like the way the mention of water, ice and channels became a commonplace in the Mars science. The whole field is being revolutionized. Can't wait for the next robotic mission to Mars.

Interesting.

Those Martian craters- have we set an age on them yet? When did the last one occur?
