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]
Much of the surface of Mars is covered by a thick smooth mantle that is thought to be a mixture of ice and dust. [46] This ice-rich mantle, a few yards thick, smoothes the land. But in places it displays a bumpy texture, resembling the surface of a basketball. Because there are few craters on this mantle, the mantle is relatively young.
The north to south distance is about 2,050 km (slightly less than the length of Greenland). [2] The quadrangle covers an approximate area of 4.9 million square km, or a little over 3% of Mars' surface area. [ 3 ]
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 ...
Many places on Mars show rocks arranged in layers. Rock can form layers in a variety of ways. Volcanoes, wind, or water can produce layers. [8] A detailed discussion of layering with many Martian examples can be found in Sedimentary Geology of Mars. [9]
Areography, also known as the geography of Mars, is a subfield of planetary science that entails the delineation and characterization of regions on Mars. [ 1 ] [ 2 ] [ 3 ] Areography is mainly focused on what is called physical geography on Earth; that is the distribution of physical features across Mars and their cartographic representations.
Mars may be around 140 million miles away from Earth, but the red planet is influencing our oceans, according to new research. Mars may be around 140 million miles away from Earth, but the red ...
Much of the surface of Mars is covered by a thick smooth mantle that is thought to be a mixture of ice and dust. [22] [23] [24] This ice-rich mantle, a few yards thick, smooths the land, but in places it has a bumpy texture, resembling the surface of a basketball. The mantle may be like a glacier and under certain conditions the ice that is ...
