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 ...
Recent evidence from SHARAD ice penetrating radar has revealed a massive subsurface CO 2 ice deposit approximately equal to 80% of the current atmosphere, or 4–5 mbar, stored in Planum Australe. [13] Depiction of erupting south polar sand-laden jets . Data from ESA's Mars Express indicates that there are three main parts to the ice cap.
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 ...
Angustus Labyrinthus is a complex of intersecting valleys or ridges near the Martian south pole (in the Mare Australe quadrangle), located at 81.68° S and 63.25° W.It was nicknamed the "Inca City" by NASA scientists due to its superficial resemblance to a ruined city. [1]
The proposed subglacial lake at the base of the South Polar Layered Deposits on Mars has a stronger radar reflection than ice or rock. Analyses are based on radar profiles (such as in the middle panel) taken by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) and was first interpreted as a subglacial lake. [1]
On December 14, 1911, Roald Amundsen became the first person to reach the geographic South Pole, part of a tragic race against Britain's Robert Scott who died of exhaustion and cold on the return ...
The Dorsa Argentea Formation (DAF) is thought to be a large system of eskers that were under an ancient ice cap in the south polar region of Mars. [1] The ancient ice cap was at least twice the size of the present ice cap and may have been 1500–2000 meters thick. [2]
Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.
