Today, Mars is believed to be largely tectonically inactive. However, observational evidence and its interpretation suggests that this was not the case further back in Mars's geological history. At the scale of the whole planet, two large scale physiographic features are apparent on the surface. The first is that the northern hemisphere of the ...
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.
Elevation map of crater Schiaparelli imaged by MGS. This is a list of craters on Mars. There are hundreds of thousands of impact craters on Mars, but only some of them have names. This list here contains only named Martian craters starting with the letter O – Z (see also lists for A – G and H – N).
This is a list of craters on Mars. Impact craters on Mars larger than 1 km (0.62 mi) exist by the hundreds of thousands, but only about one thousand of them have names. [ 1 ] Names are assigned by the International Astronomical Union after petitioning by relevant scientists, and in general, only craters that have a significant research interest ...
The Solar System is believed to have formed according to the nebular hypothesis, first proposed in 1755 by Immanuel Kant and independently formulated by Pierre-Simon Laplace. [2] This theory holds that 4.6 billion years ago the Solar System formed from the gravitational collapse of a giant molecular cloud. This initial cloud was likely several ...
In 2006, researchers using data from the OMEGA Visible and Infrared Mineralogical Mapping Spectrometer on board the Mars Express orbiter proposed an alternative Martian timescale based on the predominant type of mineral alteration that occurred on Mars due to different styles of chemical weathering in the planet's past. They proposed dividing ...
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. " Hottah " rock outcrop on Mars – ancient streambed [ 1 ] [ 2 ] [ 3 ] viewed by the Curiosity Rover (September 12, 2012, white balanced ) ( raw , close-up , 3-D version ).
A large series of rivers called the Uzboi-Ladon-Morava (ULM) system drained water from the Argyre Basin, the site of a large lake. [15] [16] [17] When an impact occurred and produced Holden crater, the system was blocked by a crater rim almost a kilometer in height. Eventually, water from drainage from the walls, with possibly a contribution ...
