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]
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 average thickness of the planet's crust is about 50 km, and it is no thicker than 125 kilometres (78 mi), [33] which is much thicker than Earth's crust which varies between 5 kilometres (3 mi) and 70 kilometres (43 mi). As a result, Mars' crust does not easily deform, as was shown by the recent radar map of the south polar ice cap which ...
NASA's Mars Reconnaissance Orbiter took an image of InSight sitting on the Martian surface on February 2, 2019. The lander was located in a flat plain called Elysium Planitia.
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
Using artificial intelligence, scientists have discovered a crater from a meteoroid that they say shook material as deep as the Red Planet’s mantle: the layer between its crust and its core.
Mars Pathfinder. Mars Exploration Rover Mission . Launched in 2003 it contained two separate rovers the Spirit rover and the Opportunity rover. Spirit One of its ...
A quake-measuring device on Mars is providing the first detailed look at the red planet's interior, revealing a surprisingly thin crust and a hot molten core beneath the frigid surface. The three ...
