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 ...
Korolev is an ice-filled impact crater in the Mare Boreum quadrangle of Mars, located at 73° north latitude and 165° east longitude.It is 81.4 kilometres (50.6 mi) in diameter [1] and contains about 2,200 cubic kilometres (530 cu mi) of water ice, comparable in volume to Great Bear Lake in northern Canada.

Scientists have announced the discovery of structures like layering and potential impact craters which had been hidden under Mars’ polar ice caps.
Mars's north polar region with ice cap, composite of Viking 1 orbiter images (Courtesy NASA/JPL-Caltech) In addition to Earth, the planet Mars also has polar ice caps. They consist of primarily water-ice with a few percent dust. [11] Frozen carbon dioxide makes up a small permanent portion of the Planum Australe or the South Polar Layered Deposits.
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 ...
Data from ESA's Mars Express indicates that there are three main parts to the ice cap. The most reflective part of the ice cap is approximately 85% dry ice and 15% water ice. The second part, where the ice cap forms steep slopes at the boundary with the surrounding plain, is almost exclusively water ice. Finally, the ice cap is surrounded by ...
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 ...
