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 Earthâs atmosphere helps support life by the providing the oxygen most air breathing organisms need to survive. Mars has barely any atmosphere. In fact the Atmosphere of Mars is so thin that it is 200 times less massive than Earthâs atmosphere. On top of that over 95 percent of the atmosphere is carbon dioxide. However breathable air is not the only issue. A planetâs atmosphere also acts as a natural barrier against high energy radiation from the Sun. Marsâ atmosphere is not thick enough to do this function effectively enough for humans. Another challenge for any human explore on Mars is the climate. On average the temperature on Mars is minus 50 degrees Celsius.
