I actually thought this was pretty cool and interesting, however could it be because the images were taken at different angles? First picture Second picture (Seem like the same but we have something new here) Third Picture Close-Ups Some of the pictures from NASA's website Image with the rock http://marsrovers.jpl.nasa.gov/gallery/all...74P1985L0M1.JPG Image without the rock http://marsrovers.jpl.nasa.gov/gallery/all...EOP0675L0M1.JPG Another image without the rock http://marsrovers.jpl.nasa.gov/gallery/all...A1P1985R0M1.JPG Finally image were the rock has been moved http://marsrovers.jpl.nasa.gov/gallery/all...EOP0675L0M1.JPG
Maybe that is a really porous rock and is being blown by the strong Martian winds. I know I move when I am being blown. DD

This post right here is why no one should ever be on ignore. Well said (but hopefully your kids aren't reading).
Oh DD you sly devil.... On subject probably a simple explanation like Martian wind or ground shifts from the freeze and thaw cycle of the ground on Mars. Or maybe just aliens.
the rover clearly moved between shots, you can see that the photos are taken from different angles. the object is clearly in the background, probably like 10-15 meters behind the rocks in the foreground. in sol 1830 the "disappearing object" is being obscured by the large boulder on the right, in 1833 it's seen between the gaps, and in 1843 you can clearly see that the rover is taking the photograph from a different angle.
Meh, it's so damn obvious and it doesn't take a rocket scientist to figure it out. You can tell that there are strong wind that could be pushing it because you see the second photo showing more expose rocks while the first image are covered in martian sands. For all we know that rock could be pretty light in material and martian gravity is lighter than earth.
They look like large martian coiled worm castings,. which when dried get blown away and fresh ones arrive on the surface as the worm moves about.
