An unknown object, possibly a stone moving on the surface of Mars, was shot by the station Mars Reconnaissance Orbiter. His pictures were published two days ago. About the unusual subject wrote in his blog Bad Astronom the researcher Phil Plait.
„The moving down the hill object was filmed near Nili Fossae – about 1500 km from the basin of Isis. However, the slope is not so steep that the stone can move by itself“ – writes Phil Plait. What mades the stone moving – is not clear yet.
Also, the trajectory of the rock is not flat – it breaks. The researcher believes that the stone has edges that make him hopping on the move.
