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.
Marsâ thin atmosphere produces a greenhouse effect but it is only enough to raise the surface temperature by 5 degrees (K); much less than what we see on Venus and Earth. Mars has permanent ice caps at both poles composed mostly of solid carbon dioxide (âdry iceâ).
