(DESCRIPTION)

Mars against a black background.

 

Text, There is abundant evidence that water flowed on Mars in the distant past.

 

We get closer to Mars. Icy tundras with great fissures in them on the surface.

 

A close-up of a large fissure.

 

Text, But does water still flow on Mars today?

 

Thin streaks down a Martian slope.

 

Text, These dark, thin, finger-like streaks advance down some Martian slopes when temperatures rise. One interpretation is that these features are caused by seasonal running water.

 

But another possibility is that they are caused by flowing sand, not water. Surface of Mars.
