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]
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 surface geology of Mars is somewhere between the basalt or andesite rocks on Earth. This led to the formation of minerals similar to what is found on Earth. The presence of iron oxide gives the surface the “rust” color that is associated with Mars, the Red Planet.
All of the rocky inner planets, as well as the moon, have an iron-dominant core. Venus and Mars have an additional major element in the core. Venus’ core is believed to be iron-nickel, similarly to Earth. Mars, on the other hand, is believed to have an iron-sulfur core and is separated into an outer liquid layer around an inner solid core.

Scientists are now proposing a new approach to warm up Earth's planetary neighbor by pumping engineered particles -similar in size to commercially available glitter and made of iron or aluminum ...

Besides heat generated by molten rock, Mars has had much heat produced when asteroids impacted its surface making giant craters. The area around a large impact may take hundreds of thousands of years to cool. [4] 243 Ida and its moon Dactyl. Dactyl is the ...
Heat Shield Rock is a basketball-sized iron-nickel meteorite found on the Meridiani Planum plain of Mars by the Mars rover Opportunity in January 2005.. Informally referred to as "Heat Shield Rock" by the Opportunity research team, the meteorite was formally named Meridiani Planum meteorite by the Meteoritical Society in October 2005 (meteorites are always named after the place where they were ...
Mars opposite Pluto calls for us to confront some of our deepest fears and desires simultaneously, according to astrologer Valerie Mesa
