Water scouring the surface? Or was it thousands years of wind-blown sand / dust? Dunes have ripples.

There is no water on Mars (not to be confused with liquid CO2) until somebody goes there and drinks some. Anything else is hoping for water to justify the $100billion price tag.

Read the article. This is from water that no longer exists on Mars.
