Too bad it is not a better shot. Possibly a spect on the lense.

Quite simply really... the secret astronaut corps that has been on Mars for sometime does service calls

Seriously?
The martian atmosphere is so thin I doubt even the fastest winds would blow over an empty wheelie bin -

Some folks looking at the tread tracks made by the Rovers are convinced they're seeing evidence of some kind of soil moisture that presents the appearance of "mud."
Other images show the rover tracks clearly are being made in "mud", with water being pressed out of that material, Levin said. "That water promptly freezes and you can see reflecting ice. That's clearly ice. It could be nothing else," he said, "and the source is the water that came out of the mud."
Originally posted by SuicideVirus I look at it and see the kind of smooth clumping that you get from a very dry powder, like baby powder. Martian sand and dust, blown around for a few million years, would tend to be extremely fine.
Scientists were also surprised by how little the soil was disturbed when Spirit's robotic arm pressed the Mössbauer spectrometer's contact plate directly onto the patch being examined. Microscopic images from before and after that pressing showed almost no change. "I thought it would scrunch down the soil particles," Squyres said. "Nothing collapsed. What is holding these grains together?"...
The instrument found the most prevalent elements in the soil patch were silicon and iron. It also found significant levels of chlorine and sulfur, characteristic of soils at previous martian landing sites but unlike soil composition on Earth.
Squyres said, "There may be sulfates and chlorides binding the little particles together." Those types of salts could be left behind by evaporating water, or could come from volcanic eruptions, he said.
