Mars has only about 0.7% of the atmospheric pressure of Earth. Mars' atmosphere is about 6.5 millibar, Earth's atmosphere is 1013 millibar. Surface of Mars is like Earth at 100,000 feet (30 kilometres) in the stratosphere. [19] [20] Mars' atmosphere's humidity is 0.03%, Earth's average humidity is about 50% (lowest 0.36%, high 100%).
The atmosphere of Mars has been losing mass to space since the planet's core slowed down, and the leakage of gases still continues today. [ 4 ] [ 8 ] [ 9 ] The atmosphere of Mars is colder than Earth’s owing to the larger distance from the Sun, receiving less solar energy and has a lower effective temperature , which is about 210 K (−63 °C ...
While Mars's climate has similarities to Earth's, including periodic ice ages, there are also important differences, such as much lower thermal inertia. Mars' atmosphere has a scale height of approximately 11 km (36,000 ft), 60% greater than that on Earth. The climate is of considerable relevance to the question of whether life is or ever has ...

Unlike Earth, Mars does not have a global magnetic field to protect its atmosphere, leaving it vulnerable to solar ultraviolet radiation. Scientists crack mystery of Mars' missing atmosphere ...
Primordial Mars also suffered from the cumulative effects of multiple small impact erosion events, [15] and recent observations with MAVEN suggest that 66% of the 36 Ar in the Martian atmosphere has been lost over the last 4 billion years due to suprathermal escape, and the amount of CO 2 lost over the same time period is around 0.5 bar or more ...
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...
A first attempt at a Mars general circulation model was created by Leovy and Mintz who used an Earth model and adapted it to Martian conditions. This preliminary model had the capability to predict atmospheric condensation of carbon dioxide and the presence of transient baroclinic waves in the winter mod-latitudes. [ 4 ]
