Mars has a very thin atmosphere that is made mostly of carbon dioxide. About 95% of Mars' atmosphere is made of CO2. There are only traces of the other gasses in its atmospher â¦ e like nitrogen and carbon monoxide.  It's atmospheric pressure is 7-9 milibars, depending on the season.
The atmosphere of Mars is so thin that liquid water probably can't persist there. Water ice sublimates directly into water vapor. Because of this, some scientists claim that Mars probably can't support the sort of life that is abundant on Earth. The atmosphere is also thought to be too cold to support liquid water.
