I've just gotta throw my 2c into this...the difference between the 1st and 2nd pictures is (to me) obviously one of shifting perspective and a parallax shift. I looked at the whitish rock in the foreground to help determine the location of the Rover. Here's a comparison:
In the 2nd photo, the Rover has moved back and to the left of the original position. The "object" is now hidden behind another rock. I haven't found a decent reference point yet in the third photo, but I assume it's even further to the left and probably back more.

Maybe the rock did move due to some sort of phenomena, rocks have been known to move about seemingly all on their own here on earth, maybe a similar thing is happening on mars.

scar7 what NASA does when it comes to the photos they will splice them like a grid l l l l l l l in this fashion in sections and overlay a veil on top of the original photo. The animals and anomalies are turned into rock formations by the program in place to disguise what you are really seeing. By the way Zorgon good to see you back your threads have been greatly missed. ^Y^

The Martian atmospheric dust particles are generally 3 µm in diameter. It is important to note that while the atmosphere of Mars is thinner, Mars also has a lower gravitational acceleration, so the size of particles that will remain in suspension cannot be estimated with atmospheric thickness alone. Electrostatic and van der Waals forces acting among fine particles introduce additional complexities to calculations. Rigorous modeling of all relevant variables suggests that 3 µm diameter particles can remain in suspension indefinitely at most wind speeds, while particles as large as 20 µm diameter can enter suspension from rest at surface wind turbulence as low as 2 ms−1 or remain in suspension at 0.8 ms−1.

But so what? Who really cares what color the Martian sky is?
