P.S.
Compare that photograph with

http://marsrovers.jpl.nasa.gov/galle...0P1938L0M1.JPG
just 18 sols earlier, where there was nothing.

I've tried to flip between the two images but can't see any differences,
apart from the lighting on the two shots.

This news is presented by "What on Mars" the best newspaper
with mars actuality in the net at:

They have a sharp eye!

Do they have a page which explains what they've seen?
