The US Space Agency publishes an image showing the effects of solar heating on the surface of the south pole of Mars.
On the picture, taken in May by the Mars Reconnaissance Orbiter and published on Last week, there are mounds that, according to the NASA (National Aeronautics and Space Administration), are formed each year with the Martian Spring when the sun starts to heat the carbon dioxide.
This material, also called "dry ice" or "dry ice", then pbades from the solid state to the gaseous state, so that it seems to melt from the base of the mounds , leaving the gas trapped beneath the surface in the first phase of spring
As this enclosed gas expands, the pressure increases to divide the crust of the mounds, giving rise to the spider-shaped reticles known as arachniform topography "described by the probe.
