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 ...
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).
An expanded crater is a type of secondary impact crater. [22] Large impacts often create swarms of small secondary craters from the debris that is blasted out as a consequence of the impact. [22] Studies of a type of secondary craters, called expanded craters, have given us insights into places where abundant ice may be present in the ground.
Crater morphology provides information about the physical structure and composition of the surface and subsurface at the time of impact. For example, the size of central peaks in Martian craters is larger than comparable craters on Mercury or the Moon. [52] In addition, the central peaks of many large craters on Mars have pit craters at their ...
Korolev is an ice-filled impact crater in the Mare Boreum quadrangle of Mars, located at 73° north latitude and 165° east longitude.It is 81.4 kilometres (50.6 mi) in diameter [1] and contains about 2,200 cubic kilometres (530 cu mi) of water ice, comparable in volume to Great Bear Lake in northern Canada.

The crater Nhill and its surroundings, in a screenshot in NASA World Wind. This is a partial 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 only contains named Martian craters starting with the letter H – N (see also lists for A – G and O – Z).
Jezero on the edge of the Isidis basin. Jezero [a] (ICAO: JZRO) is a crater on Mars in the Syrtis Major quadrangle, [3] about 45.0 km (28.0 mi) in diameter. Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. [4]
Additionally, many new craters are first noticed by their 'blast zone' of ejecta, which can be 10-100 times the size of the crater itself. [5] However, only certain regions of Mars have subsurface material that can be ejected to create these features; in particular, the Tharsis rise, Olympus Mons, Elysium Mons, and Arabia Terra. As a result ...
