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 ...

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 ...
Mars atmospheric entry is the entry into the atmosphere of Mars. High velocity entry into Martian air creates a CO 2 -N 2 plasma, as opposed to O 2 -N 2 for Earth air. [ 1 ] Mars entry is affected by the radiative effects of hot CO 2 gas and Martian dust suspended in the air. [ 2 ]
However, early in its history Mars may have had conditions more conducive to retaining liquid water at the surface. Mars without a dust storm in June 2001 (on left) and with a global dust storm in July 2001 (on right), as seen by Mars Global Surveyor. Early Mars had a carbon dioxide atmosphere similar in thickness to present-day Earth (1000 hPa ...
