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 Mars Exploration Rover Opportunity landed in an area containing cross-bedded (mainly eolian) sandstones (Burns formation [64]). Fluvial-deltaic deposits are present in Eberswalde Crater and elsewhere, and photogeologic evidence suggests that many craters and low lying intercrater areas in the southern highlands contain Noachian-aged lake ...
Topographic map of Mars showing the highland-lowland boundary marked in yellow, and the Tharsis rise outlined in red (USGS, 2014).[1]Like the Earth, the crustal properties and structure of the surface of Mars are thought to have evolved through time; in other words, as on Earth, tectonic processes have shaped the planet.
Now, a new discovery by NASA’s Perseverance rover shows a trifecta of compelling evidence—including the presence of water, organic compounds, and a chemical energy source—all on one rock ...
This is the "best evidence yet" that Mars still has liquid water in addition to frozen water at its poles, according to the University of California, San Diego's Scripps Institution of ...
In addition to rock covered glaciers around mesas, the region has many steep-walled valleys with lineations—ridges and grooves—on their floors. The material comprising these valley floors is called lineated valley fill. In some of the best images taken by the Viking Orbiters, some of the valley fill appeared to resemble alpine glaciers on ...
A 2023 study shows evidence, based on the orbital inclination of Deimos (a small moon of Mars), that Mars may once have had a ring system 3.5 billion years to 4 billion years ago. [32] This ring system may have been formed from a moon, 20 times more massive than Phobos , orbiting Mars billions of years ago; and Phobos would be a remnant of that ...
Scientists have announced the discovery of structures like layering and potential impact craters which had been hidden under Mars’ polar ice caps.
