Mars has an atmosphere, though it is different than our atmosphere here on Earth. The atmosphere of Mars is thin, cold, and dry and contains much less oxygen than the atmosphere of Earth. The oxygen content of the Martian atmosphere is only 0.13 percent, compared with 21 percent in Earth's atmosphere.
Oxygen gas (dioxygen, O 2) makes up 21% of the atmosphere by volume. It is the most abundant element in the earth's crust (followed by silicon). It is present in any number of minerals and makes up most of the weight of water. Oxygen is the third most abundant element found in the sun, and is involved in the carbon-nitrogen cycle, one of the processes responsible for stellar energy production. The atmosphere of Mars contains about 0.15% oxygen.
