The Martian atmosphere is the very definition of “thin air”. Its atmospheric pressure is about a hundred times less than Earth’s. Future Mars explorers will not be able to breathe Martian air because it’s almost completely carbon dioxide with a few traces of nitrogen, oxygen, and water vapor. 2021-04-07 · Additional chapters examine Mars's fascinating climate history, ranging from planetary formation to the most recent centuries. Most interesting to non-specialists may be the climate history, which suggests Mars once resembled Earth with a thick atmosphere, abundant precipitation and ground water, and possibly an ocean. File:PIA22737-Mars-2018DustStorm-MCS-MRO-Animation-20181030.webm 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).

Most interesting to non-specialists may be the climate history, which suggests Mars once resembled Earth with a thick atmosphere, abundant precipitation and ground water, and possibly an ocean. For this reason, early Mars was presumably friendlier to possible life than the frigid, desiccated surface - with atmospheric pressure less than 1 percent of Earth's - that we see now. As for the rest of Mars' atmosphere, it was likely blown off under the assault of solar wind. Earth's magnetic field protects us from the worst of such effects, but the Mars equivalent shut down around 4 billion years ago, possibly due to a series of massive asteroid impacts that threw off the temperature gradient powering the planetary electric dynamo [source: Than ].

A Mars aircraft is a vehicle for flying in the atmosphere of Mars. So far, only lander entry, descent, and landing systems have operated in the Martian atmosphere. Aircraft may provide in situ measurements of the atmosphere of Mars , as well as additional observations over extended areas. The atmosphere of Mars is the layer of gases surrounding Mars composed mostly of carbon dioxide.The atmospheric pressure on the Martian surface averages 600 pascals (0.087 psi), about 0.6% of Earth's mean sea level pressure of 101.3 kilopascals (14.69 psi).
