Nasa's Mars Reconnaissance Orbiter has spotted traces of carbon dioxide ice on the Red Planet. The orbiter has found that carbon dioxide ice more often covers the ground at night in some mid-latitude regions than in polar regions of the Red Planet.
Carbon dioxide is the main ingredient of Mars' atmosphere. The planet also has large reserves of frozen carbon dioxide buried in the polar ice caps.
