Atmosphere of Mars
The atmosphere of the planet Mars is composed mostly of carbon dioxide . The atmospheric pressure on the Martian surface averages 600 pascals (0.087 psi ; 6.0 mbar ), about 0.6% of Earth's mean sea level pressure of 101.3 kilopascals (14.69 psi; 1.013 bar). It ranges from a low of 30 pascals (0.0044 psi; 0.30 mbar) on Olympus Mons 's peak to over 1,155 pascals (0.1675 psi; 11.55 mbar) in the depths of Hellas Planitia . This pressure is well below the Armstrong limit for the unprotected human body. Mars 's atmospheric mass of 25 teratonnes compares to Earth's 5148 teratonnes ; Mars has a scale height of 11.1 kilometres (6.9 mi) [2] versus Earth's 8.5 kilometres (5.3 mi). [3]

The atmosphere of Mars is, like that of Venus , composed mostly of carbon dioxide though far thinner. There has been renewed interest in its composition since the detection of traces of methane in 2003 [2] [3] that may indicate life but may also be produced by a geochemical process, volcanic or hydrothermal activity .
