surface water on mars

just looking at some mars rover photos, and it looks like surface water:

even in the bottom right of this image, there is a water-carved groove with some of the same looking substance as in the rest of the pic, which looks like water in 'puddles' in the low points of the bedrock




image comes from here, that does not mention this thing that looks like puddles of water

Also this image to me looks like what we in Australia call a 'water hole' which are common. They say that this is sand dunes, but it certainly looks more like rippling water than sand dunes to me..



this image is from here

and the fact that they say this is reverse image does not convince me. It looks pretty much what I'd imagine it to be before a reverse image is applied to it .. . maybe someone can reverse their reverse image?

Ummm, to me that is most definately water. Are these real mars photos im wondering? Cuz it doesnt take a scientist to see that what we are looking at is clearly liquid.
If its legit, good find. Props, starred and flagged.
-Z-

the first image, the majority of it looks like fine sand or dust, except when you look at the bottom corner (right) that looks like a channel with water flowing through it.

the 2nd image looks like its been edited, blurred or something because you can see through it if you look closely not sure but looks cool

ArMaP will be along shortly and correct your thinking on this 'water'

So before he pounces and spoils your fun....

Okay now ArMaP will be here soon to explain it is all just dry sand

If you are a fisherman, you know that ripples are caused by wind. There is absolutely no dust stirring, no indication of any wind.. yet the water is rippling? Based on that alone, I'd say that is indeed, sand dunes. As are the others. The "stream" is intersting though, I admit. Of course, ice can form that way as well, so a possibility.

First one is definetly sand, probably really fine sand.
Second pic is.... sand.
Lighter sand in a channel forming sand ripples. If you look at a larger, zoomed out photo, you'll see the larger version we call sand dunes.
Sorry to sound like a grump, but this gets rehased about every other month or so, check back on ATS.

I hadn't seen your 'favorite' one before. I don't think they are muddy tracks at all, they don't look any different than any other tracks it made. But that looks more water-like than anything I've seen previously. And it's almost as if they sent the rover that to check that out, see if it was indeed water. That doesn't mean it is water, it could still simply be sand, but.... the white bit to the right, dim as it is, does look underwater.

Is that the high-rez version? Or is there a more complete / high res photo of that particular crater?

Changing the hue of images to blue wont turn sand into water in reality.
There is a lot of water on mars, mostly underground or frozen. Why cling to straws ?

I challenge you to go out to any sandy spot on Earth... the desert... a beach... whatever...

Now take a wheel (Toy whatever) and make deep tracks in the sand... You can just use a shovel

I want you to observe what happens when the sand is absolutely dry... even deep down...

Show me the color change from light to dark.

Now do the same thing until you expose the deeper damp soil and observe the color change from light to dark... the watch as the sun dries it and shows the color difference vanish as the sand dries...

Now take some fine powder like flour... and show me tracks through the flour that look like slipping on mud... as ArMaP believes is what is happening...

When you can duplicate these observed effects on Earth and take a picture... I might agree with you...

HOWEVER bear in mind that the Phoenix Lander just did this very experiment on Mars... it used a simple scoop to scrap a few inches into the soil and guess what? They found frozen water just below the surface...

Now why would it be a surprise that the same thing happens on other locations on Mars?

Well in that photo it actually is sand What they sent the Rover to look at was this...



The one that is ABSOLUTELY water ice is the ESA Crater Lake... because that is backed up by spectroscopic data... just like the frozen lake on the moon announced by the Pentagon

Is that the high-rez version? Or is there a more complete / high res photo of that particular crater?

The high res version is linked below the picture where it says FULL SIZE... please go back and click on it there

Bluebirds work on Water on Mars for those seriously interested... and I am still waiting for StellarX's material

Haven't seen either of them around lately though... what's up with that?
