The Mare Acidalium quadrangle is also referred to as MC-4 (Mars Chart-4). [1] The southern and northern borders of the quadrangle are approximately 3,065 km and 1,500 km wide, respectively. The north to south distance is about 2,050 km (slightly less than the length of Greenland). [2]
Mars is a terrestrial planet, which has undergone the process of planetary differentiation. The InSight lander mission is designed to study the deep interior of Mars. [8] The mission landed on 26 November 2018. [9] and deployed a sensitive seismometer to enable 3D structure mapping of the deep interior. [10]
The quadrangles appear as rectangles on maps based on a cylindrical map projection, [1] but their actual shapes on the curved surface of Mars are more complicated Saccheri quadrilaterals. The sixteen equatorial quadrangles are the smallest, with surface areas of 4,500,000 square kilometres (1,700,000 sq mi) each, while the twelve mid-latitude ...
Places on Mars that display polygonal ground may indicate where future colonists can find water ice. Patterned ground forms in a mantle layer, called latitude dependent mantle, that fell from the sky when the climate was different. [65] [66] [89] [90]
Mars is differentiated, which—for a terrestrial planet—implies that it has a central core made up of high density matter (mainly metallic iron and nickel) surrounded by a less dense, silicate mantle and crust. [4] Like Earth, Mars appears to have a molten iron core, or at least a molten outer core. [5]
Seismic waves generated by a meteorite impact on the other side of Mars from where NASA's InSight lander sits have provided new clues about the Red Planet's deep interior, prompting scientists to ...
Topographic map of Mars showing the highland-lowland boundary marked in yellow, and the Tharsis rise outlined in red (USGS, 2014).[1]Like the Earth, the crustal properties and structure of the surface of Mars are thought to have evolved through time; in other words, as on Earth, tectonic processes have shaped the planet.
