  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 ...

    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 ...

  4. 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 ...

    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 ...

    en.wikipedia.org/wiki/Areography

    Residual north and south polar ice caps are shown at upper and lower right as they appear in early summer and at minimum size, respectively. Areography , also known as the geography of Mars , is a subfield of planetary science that entails the delineation and characterization of regions on Mars .

  8. Climate of Mars - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Mars

    Mars has ice caps at its north pole and south pole, which consist mainly of water ice; however, there is frozen carbon dioxide present on their surfaces. Dry ice accumulates in the north polar region ( Planum Boreum ) in winter only, subliming completely in summer, while the south polar region additionally has a permanent dry ice cover up to ...
