Atmosphere of Mars, illustration. Mars is a rocky desert world with no surface water. The atmosphere is mostly carbon dioxide and Martian surface temperatures are well below freezing. Water vapour is present in the atmosphere, which is close to saturation point at these temperatures and pressure. This leads to the formation of clouds (white). Dust storms (grey) are also relatively common, with one shown here below the clouds. At upper right is a meteor impacting the atmosphere. Impact craters, mesas and canyons, are present on the surface. The Martian atmosphere extends to a height of around 200 kilometres as it tapers out into space. Planetary atmospheres are compared using scale heights. The Martian atmosphere has a scale height of 11 kilometres compared to Earth's scale height of 8.5 kilometres. | |
