If Mars has permanent COpolar caps, atmospheric heat transport may cause the atmospheric pressure to be extremely sensitive to variations of solar heating at the poles. This could happen because atmospheric heating depends on density, which depends strongly on the polar temperature through the vapor ...
It relies on the accuracy of the atmospheric density model, and its computational complexity is very high which limits its application.

the internal spatial distribution of its density can be determined; this distribution can be mapped with muography by identifying where these muons passed through the object and subsequently creating a plot of the number of penetrating muons on a 2-dimensional plane. The origin of these high-energ...
Measurements of electron density by the Pioneer Venus Orbiter electron temperature probe showed extreme spatial irregularities in the form of detached plasma clouds on the night side of Venus. It is suggested that Kelvin Helmholtz (KH) instabilities may trigger such ionospheric bubbles on Mars too. ...
However, one can gain physical insight into the characteristics of the entry trajectory by developing approximate solutions. Reduced-order solutions are obtained by employing the following assumptions: (1) atmospheric density is modeled by an exponential function; (2) gravitational acceleration g is ...
