Planum Australe (Latin: "the southern plain") is the southern polar plain on Mars.It extends southward of roughly 75°S and is centered at The geology of this region was to be explored by the failed NASA mission Mars Polar Lander, which lost contact on entry into the Martian atmosphere.
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]
At the south pole, a small residual cap of CO 2 ice remains in summer. Both residual ice caps overlie thick layered deposits of interbedded ice and dust. In the north, the layered deposits form a 3 km-high, 1,000 km-diameter plateau called Planum Boreum. A similar kilometers-thick plateau, Planum Australe, lies in the south. Both plana (the ...
PHOTO: This image from NASA's Mars Reconnaissance Orbiter, acquired May 13, 2018, during winter at the South Pole of Mars, shows a carbon dioxide ice cap covering the region.
This is a list of plains on Mars. Such features are named after the nearest classical albedo feature in compliance with the International Astronomical Union 's rules of planetary nomenclature . Plains may be named denoted " planitia " or "planum", depending on height.
New research published Monday in the journal Nature Astronomy indicates there really is a buried reservoir of super-salty water near the south pole of the planet. Are there super-salty lakes on Mars?
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
The maps below were produced by the Mars Global Surveyor ' s Mars Orbiter Laser Altimeter; redder colors indicate higher elevations.The maps of the equatorial quadrangles use a Mercator projection, while those of the mid-latitude quadrangles use a Lambert conformal conic projection, and the maps of the polar quadrangles use a polar stereographic projection.
