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 also has an atmosphere that plays a role in ejecta emplacement and subsequent erosion. Moreover, Mars has a rate of volcanic and tectonic activity low enough that ancient, eroded craters are still preserved, yet high enough to have resurfaced large areas, producing a diverse range of crater populations of widely differing ages.
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.

A year later, Hilder has used his campaign against "Wasters" to gain power in Earth's Assembly, and has just reduced shipments of water to Mars, putting the Scavengers out of work. When Hamish Sankov, the head of the Martian colony, learns of Hilder's plan to terminate all water shipments to Mars, he authorizes Long's plan to travel to Saturn ...
Observations of the Mars Exploration Rovers’ magnetic dust traps suggest that about 45% of the elemental iron in atmospheric dust is maximally oxidized (Fe 3+) and that nearly half exists in titanomagnetite, [47] both consistent with mechanical derivation of dust with aqueous alteration limited to just thin films of water. [48]
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 ...
The exact correlation varied over time, and in early centuries bronze or electrum were sometimes found instead of mercury, or copper for Mars instead of iron; however, gold, silver, and lead had always been associated with the Sun, Moon, and Saturn. [note 1] The associations below are attested from the 7th century and had stabilized by the 15th ...
