What is the composition of mars' atmosphere?
The atmosphere of Mars is the layer of gas surrounding Mars. It is primarily composed of carbon dioxide (95.32%), molecular nitrogen (2.6%) and argon (1.9%). It also contains trace levels of water vapor, oxygen, carbon monoxide, hydrogen and other noble gases. The atmosphere of Mars is much thinner than Earth's. The surface pressure is only about which is less than 1% of the Earth's value. The currently thin Martian atmosphere prohibits the existence of liquid water at the surface of Mars, but many studies suggest that the Martian atmosphere was much thicker in the past. The highest atmospheric density on Mars is equal to the density found 35 km above the Earth's surface. The atmosphere of Mars has been losing mass to space throughout history, and the leakage of gases still continues today.

What is the composition of mars' atmosphere of Argon?
1.9%
The estimated mean volume ratio of molecular oxygen (O) in the Martian atmosphere is 0.174%. It is one of the products of the photolysis of CO, water vapor and ozone (O). It can react with atomic oxygen (O) to re-form ozone (O). In 2010, the Herschel Space Observatory detected molecular oxygen in the Martian atmosphere.

Carbon monoxide (CO) is produced by the photolysis of CO and quickly reacts with the oxidants in the Martian atmosphere to re-form CO. The estimated mean volume ratio of CO in the Martian atmosphere is 0.0747%.

Atmosphere of Mars
Mars' atmosphere is thinner than Earth's. The atmosphere of Mars is comprised of a layer of gases with Carbon Dioxide being the most at 95.32%, and Nitrogen at 2.6%. The rest of the gases are trace amounts such as 1.9% Argon, 0.174% Oxygen, 0.0747% Carbon Monoxide, and 0.03% Water Vapor.
