  2. Martian polar ice caps - Wikipedia

    en.wikipedia.org/wiki/Martian_polar_ice_caps

    1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...

    Image of the Mare Boreum Quadrangle (MC-1). The region includes the North Polar ice cap, Korolov crater and Chasma Boreale. The Mare Boreum quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Mare Boreum quadrangle is also referred to as MC-1 (Mars ...

    The Mare Australe quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Mare Australe quadrangle is also referred to as MC-30 (Mars Chart-30). [1] The quadrangle covers all the area of Mars south of 65°, including the South polar ice cap, and its ...

    Mars has two permanent polar ice caps, the northern one located at Planum Boreum and the southern one at Planum Australe. The difference between Mars's highest and lowest points is nearly 30 km (from the top of Olympus Mons at an altitude of 21.2 km to Badwater Crater [1] at the bottom of the Hellas impact basin at an altitude of 8.2 km below ...

  7. Polar ice cap - Wikipedia

    en.wikipedia.org/wiki/Polar_ice_cap

    A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice. [ 1 ] There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land, but only that it must be a body of solid phase ...

    en.wikipedia.org/wiki/Geology_of_Mars

    The polar ice caps are well-known telescopic features of Mars, first identified by Christiaan Huygens in 1672. [42] 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 ...
