Sagot :
There is a water on Mars but mainly frozen, in the south and north polar cap. But there is findings that liquid water must be flowing on its surface.
Mars has a lot of flood and river channels suggesting that a long time ago liquid water flowed on Mars during a time when Mars was a warm and wet planet with a thicker atmosphere. There is recent evidence thatthere may also be liquid water at or near the surface on Mars in some places, but this has yet to be proven.
