Are the gods playing marbles on Mars?
New Scientist ^ | 6/11/13 | Victoria Jaggard

A rolling stone gathers no moss – but on Mars it can nevertheless cloak itself in mystery. This NASA image shows the track of a boulder that rolled across the Nili Fossae region of Mars. For now it is anyone's guess what set the rock in motion.

This false-colour picture (click on it for higher resolution) was posted on 7 June to the Beautiful Mars Tumblr feed, a collection of high-resolution shots from the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter. It shows dark, jagged tracks left in the soil by a lumpy boulder, probably a few metres wide, as it tumbled down a slope. A handful of smaller rocks (seen on the right) also made dotted lines as they rolled.

good try but the object didn't evaporate and is still at the bottom of the trail... if they take another picture and it's gone then it could very well be, if it's still there, prolly not

Since it was perched on a hill, I'd say gravity had something to do with it.

Now... if it rolled across a flat surface, then I would question how that happened.

Happens here on Earth.

Have they figured out how those move yet?

This puzzle isn’t really hard. It was on an incline, and Mars has seismic activity, just as every planetary body does, including our moon.

The theory is that moisture in the air condenses at night, on the surface, and capillary action causes it to be sucked between the rock and the dry ground underneath, giving the rock a ‘lift’ off the ground suspended on a small pad of water. Then... the wind moves the almost resistance free rock across the ‘racetrack’.

Could it be simply a huge rock fallen down a hill ?

Flux in the magnetic field of Mars?

Maybe a tiny marsquake?

What I find interesting is that the two rocks in the picture seem to follow almost identical paths.

I have wondered if it’s not the wind, but the gravitational pull from the moon that moves them.

People might say that’s silly, but the moon lifts the surface of the world’s oceans every day.

I guess it is possible.

However, the orbit of Jupiter is very slow and wouldn’t account for the zigzag movement.

Jupiter could have pulled the rocks down the hills on Mars, though.

The rock cliff in that picture looks like something you would see at the grand canyon.

Clearly, someone or something on Mars has lost its marbles. /rimshot!
