Default Re: Snowing on Mars!!!

Now Viking already showed us the Martian Temperature...

Atmospheric temperatures are the featured Pathfinder meteorological observations and the temperatures encountered at the surface of Earth and Mars provide the primary basis for these developments. The temperatures on the two Viking landers, measured at 1.5 meters above the surface, range from + 1° F, ( -17.2° C) to -178° F (-107° C). However, the temperature of the surface at the winter polar caps drop to -225° F, (-143° C) while the warmest soil occasionally reaches +81° F (27° C) as estimated from Viking Orbiter Infrared Thermal Mapper. The diurnal cycle of atmospheric temperature is as important meteorologically as it is on Earth, but it is less important in other contexts: the reason will become evident in the lessons that follow. The diurnal temperature variation at Viking Lander 1 at the same season as Pathfinder is landing is illustrated here and described below.

Plus 81 degrees fahrenheit... sounds downright balmy

So what happens when you mix known water ice with known temperature of PLUS 81 degrees F???
