Numerous attempts [4] [5] [6] have been made over the years to determine an absolute Martian chronology (timeline) by comparing estimated impact cratering rates for Mars to those on the Moon. If the rate of impact crater formation on Mars by crater size per unit area over geologic time (the production rate or flux) is known with precision, then ...
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 common surface features of Mars include dark slope streaks, dust devil tracks, sand dunes, Medusae Fossae Formation, fretted terrain, layers, gullies, glaciers, scalloped topography, chaos terrain, possible ancient rivers, pedestal craters, brain terrain, and ring mold craters.
Mars is a rocky planet, like Earth, that formed around the same time, yet with only half the diameter of Earth, and a thin atmosphere; it has a cold and desert-like surface. [10] One way the surface of Mars has been categorized, is by thirty "quadrangles", with each quadrangle named for a prominent physiographic feature within that quadrangle.
Rocks on Mars have been found to frequently occur as layers, called strata, in many different places. Columbus Crater is one of many craters that contain layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [83] Many places on Mars show rocks arranged in layers.
Curiosity rover on Mars (5 August 2015). The Mars Science Laboratory and its rover, Curiosity, were launched from Earth on 26 November 2011. As of November 24, 2024, Curiosity has been on the planet Mars for 4373 sols (4493 total days; 12 years, 110 days) since landing on 6 August 2012.
