A possible plate tectonic explanation for the northern lowlands. The Boreal plate is shown in yellow. Trenches are shown by toothed lines, ridges by double lines, and transform faults by single lines, modified from Sleep, 1994. [11] Endogenic hypotheses include the possibility of a very early plate tectonic phase on Mars. [11]
First discovered on images from Mars Global Surveyor, they occur on steep slopes, especially on the walls of craters. Usually, each gully has a dendritic alcove at its head, a fan-shaped apron at its base, and a single thread of incised channel linking the two, giving the whole gully an hourglass shape. [ 13 ]
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 Medusae Fossae Formation is a large geological formation of probable volcanic origin on the planet Mars. [1] It is named for the Medusa of Greek mythology. "Fossae" is Latin for "trenches". The formation is a collection of soft, easily eroded deposits that extends discontinuously for more than 5,000 km along the equator of Mars.
A marsquake is a quake which, much like an earthquake, is a shaking of the surface or interior of the planet Mars. Such quakes may occur with a shift in the planet's interior, such as the result of plate tectonics, from which most quakes on Earth originate, or possibly from hotspots such as Olympus Mons or the Tharsis Montes.
New images from NASA’s Mars Reconnaissance Orbiter may show where life first began on Mars. The site on southern Mars shows massive deposits in a basin that scientists say were formed a long ...
The most detailed images and observations ever captured of one of Mars' moons have been released by scientists. Pictures taken by Hope Probe from the UAE Space Agency's Emirates Mars Mission (EMM ...
By Eric Sandler On August 20, 1975 -- 39 years ago today -- NASA launched the first of two spacecraft as a part of their new Viking program and the images they captured back in the '70s and '80s ...
