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.
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 ...
Areography, also known as the geography of Mars, is a subfield of planetary science that entails the delineation and characterization of regions on Mars. [ 1 ] [ 2 ] [ 3 ] Areography is mainly focused on what is called physical geography on Earth; that is the distribution of physical features across Mars and their cartographic representations.
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?
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.
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]
Intuitive Machines' Athena lunar lander is seen integrated with the SpaceX Falcon 9 rocket that will propel it into orbit before it separates and continues on its voyage to the moon.
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.
