This reveals the only known example of carbon dioxide snow
falling anywhere in our solar system.
Up to a third of the huge ice caps evaporates into gas every summer and falls back in winter as carbon dioxide snow
, say the team at the NASA-Goddard Space Flight Centre in Maryland, USA.
Liquid Nitrogen or Carbon Dioxide Snow
(Dry Ice) can be used to cool the product to the desired temperature, leaving no residue behind as they vaporise.
Although they're not the type you can stick out your tongue and lick, as Massachusetts Institute of Technology researchers have found that the carbon dioxide snow
particles(http://web.mit.edu/newsoffice/2012/co2-snow-on-mars-0619.html) are roughly the size of a human red blood cell .
Washington, June 20 ( ANI ): Researchers at MIT have determined the size of carbon dioxide snow
particles in clouds at both Martian poles from data gathered by orbiting spacecraft.
