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]
Octavia E. Butler Landing is the February 18, 2021, landing site of the Mars 2020 Perseverance rover within Jezero crater on planet Mars. On March 5, 2021, NASA named the site for the American science fiction author, Octavia E. Butler, who died on February 24, 2006. The Mars landing took place nearly 15 years to the day after her death.
In particular, precipitation induced surface runoff and groundwater seepage resulted in the formation of fluvial landforms, i.e., dense valley networks, [2] broad and elongated valleys, delta deposits, alluvial fans, open-basin paleolakes and coastlines. Crater size - frequency distribution measurements ("crater counting") revealed that the ...
Research reported in 2017 found that the amount of water needed to develop valley networks, outflow channels, and delta deposits of Mars was larger than the volume of a Martian ocean. The estimated volume of an ocean on Mars ranges from 3 meters to about 2 kilometers GEL (Global equivalent layer). This implies that a large amount of water was ...
Ore resources on Mars – Ore deposits on Mars that may be useful to future colonists; Outflow channels – Long, wide swathes of scoured ground on Mars; Valley network (Mars) – Branching networks of valleys on Mars; Vallis – Valley landform on other planets; Water on Mars – Study of past and present water on Mars
Changes in Mars' orbit and tilt cause significant changes in the distribution of water ice from polar regions down to latitudes equivalent to Texas. During certain climate periods water vapor leaves polar ice and enters the atmosphere. The water comes back to ground at lower latitudes as deposits of frost or snow mixed generously with dust.
Reconciling the geologic evidence of river valleys and lakes with computer climate models of Noachian Mars has been a major challenge. [16] Models that posit a thick carbon dioxide atmosphere and consequent greenhouse effect have difficulty reproducing the higher mean temperatures necessary for abundant liquid water. This is partly because Mars ...
This is a partial list of named channel structures on Mars claimed as outflow channels in the literature, largely following The Surface of Mars by Carr. The channels tend to cluster in certain regions on the Martian surface, often associated with volcanic provinces, and the list reflects this.
