Martian polar ice caps - Wikipedia
WEBThe planet Mars has two permanent polar ice caps. During a pole's winter, it lies in continuous darkness, chilling the surface and causing the deposition of 25–30% of the atmosphere into slabs of CO 2 ice ( dry ice ). When the poles are again exposed to sunlight, the frozen CO 2 sublimes. [1]
Geology of Mars - Wikipedia
WEBThe polar ice caps are well-known telescopic features of Mars, first identified by Christiaan Huygens in 1672. Since the 1960s, we have known that the seasonal caps (those seen in the telescope to grow and wane seasonally) are composed of carbon dioxide (CO 2 ) ice that condenses out of the atmosphere as temperatures fall to 148 K, the frost ...
Water on Mars - Wikipedia
WEBAbundant water ice is also present beneath the permanent carbon dioxide ice cap at the Martian south pole. More than 5 million km 3 of ice have been detected at or near the surface of Mars, enough to cover the whole planet to a depth of 35 meters (115 ft). [13]
