The density of Mars is about 30 % less than that of Earth (3.94 g/cm3 vs. 5.52 g/cm3). Its core is probably similar to Earth's, mostly iron, with small amounts of nickel, but spacecraft mapping of its gravity field seem to indicate that its iron-rich core and mantle are a smaller portion of its volume than on Earth. Also, its smaller magnetic field than Earth, indicates a solid, rather than liquid core.
Mars' atmosphere is 95 % carbon dioxide, nearly 3 % nitrogen, and nearly 2 % argon with trace quantities of oxygen, carbon monoxide, water vapor, ozone, and other trace gases.
