Water on Mars

Do we really have flowing water on Mars? What quantity of water are we talking about?

We have not seen flowing water on the surface. If there is liquid water, think of this as a “seep” not a flow. We see something that darkens the soil, which may be just a wetting action but still involves (briny) liquid.

We think this is a very small amount of water—maybe just enough to wet the top layer of the surface of Mars. The streaks are about 5 meters wide and between 200 and 300 meters long.
