    William Herschel was the first to deduce the low density of the Martian atmosphere in his 1784 paper entitled On the remarkable appearances at the polar regions on the planet Mars, the inclination of its axis, the position of its poles, and its spheroidal figure; with a few hints relating to its real diameter and atmosphere. When Mars appeared ...

    The Mars general circulation model is the result of a research project by NASA to understand the nature of the general circulation of the atmosphere of Mars, how that circulation is driven and how it affects the climate of Mars in the long term.

  5. Mars atmospheric entry - Wikipedia

    en.wikipedia.org/wiki/Mars_atmospheric_entry

    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 ]

    1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...

    The atmosphere of Mars consists of about 96% carbon dioxide, 1.93% argon and 1.89% nitrogen along with traces of oxygen and water. [ 2 ] [ 120 ] [ 114 ] The atmosphere is quite dusty, containing particulates about 1.5 μm in diameter which give the Martian sky a tawny color when seen from the surface. [ 121 ]
