Nanedi Valles on Mars

[FLO]

This image, taken by ESA's Mars Express spacecraft, shows the Nanedi Valles region of Mars. These steep sided channels range in width from a few hundred meters to more than 5km (3 miles) across, and look like they were formed by quickly flowing water. But their origin is debated by researchers. Some think that liquid flowed under the surface and the ground collapsed above it, while others think that water did once flow on the surface.
