The seasonal caps on Mars are composed not of ordinary snow but of frozen CO 2 (dry ice). These deposits condense directly from the atmosphere when the surface temperature drops below about 150 K. The caps develop during the cold martian winters and extend down to about 50° latitude by the start of spring.
