Nasa’s Mars Reconnaissance Orbiter provide a proof of data that carbon dioxide snowfalls on Mars. It further reveals that carbon dioxide snow falling anywhere in our Solar system.
Paul Hayne of Nasa's jet propulsion laboratory (JPL) in Pasadena, California report’s shows that Frozen carbon dioxide needs a temperature of about -125 °C which is more than required to freeze water. The detection of carbon dioxide snow clouds reminds the scientists that some parts of Mars look quite Earth-like.
Hyne said that flakes of Martian air which are thick enough to result in snowfall accumulation at the surface. The Red Planet in the winter around its south pole gets the snowfall as the carbon dioxide ice particles in the clouds are large enough to fall on the surface of the Mars.
