Now, for the open minded, I present this interesting image .... again, we don't know what it shows, for sure; we just know it shows SOMETHING.
Another big something if you look at the crater in the image. Look at the possibility of flowing water into the crater and withing the crater.
We don't know what that big z of lighter colour is? It suggests a light source? A flash of colour which contends that there is perhaps a dust storm happening? It's so hard to tell considering the background is blue which is clearly not the correct colour for the image. We will look into this and report back.
