Hello to all!
today I've stumbled upon a new image from the Curiosity rover.
The original can be seen here:

http://mars.jpl.nasa.gov/msl/multimedia/images/?ImageID=6236

I've noticed, all around the material dug out from the hole, kinda "wet path" Shocked
Usually can be seen at the sea, while digging a hole at the shores, in the sand
Here you can see what I', referring to:

maybe it's just an optical illusion, but seem that something "wetted" the excavated sand. and flown away in the upper left of the image.!!!
Anyone agree??? Very Happy

Thanks for the annotated image and your outside-the-box ideas. That "wet path" is precisely what I was referring to a few days ago when I posted some images of the same hole and the clearly demarcated "wet area" around the droppings from the hole resulting from the 2nd drilling.

There were however no takers in the MRB family to the idea.

Closeups of the area only showed a high concentration of the microspheres in a slightly discoloured area. I've also posted them here.

I think that the wet droppings most likely left the discolouration on the rock surface after the wet droppings sublimed its small water content.

Ciao LWS!
many thanks for your posted comment... Very Happy
In the image can also be seen, around the hole, some big blobs, maybe water mixed with soil sputter all around by the drill action.
More or less like the "drops" can be seen on some of the under legs of the Mars Polar lander.
Im' starting to think at Mars as a iced "sponge" of sand and water: we cannot see liquid water due to the low atmospheric pressure and the freezing temperature... but under, IN THE SOIL there should be enourmous quantities of water... do you agree? Rolling Eyes Wink

I agree somewhat but I think that the water in the soil is fairly limited although of significant amounts. The DAN instrument put the average water content in the soil over which Curi traversed at 4 percent, i.e. not enormous but not trivial either.

The orbital assessment of water content also showed the Gale crater area as one of the highest along the equitorial range of Mars features, and estimated 4+ percent content. High figure for a Mars location at the solar incidence angle.
