Mars, the 4th planet from the Sun, has a very different atmosphere from that of the Earth. There has been much interest in studying its composition since the recent detection of a small amount of methane,which may signal life on Mars; it could also be a geochemical process or the result of volcanic or hydrothermal activity.The atmosphere of Mars is relatively thin, and the atmospheric pressure on the surface varies from around 30 Pa (0.03 kPa) on Olympus Mons's peak to over 1155 Pa (1.155 kPa) in the depths of Hellas Planitia, with a mean surface level pressure of 600 Pa (0.6 kPa, or 6 millibars, or 0.087 psi), compared to Earth's 101.3 kPa, and a total mass of 25 teratonnes, compared to Earth's 5148 teratonnes. However, the scale height...
