A1_5 Methane Mars

Abstract

Here, we consider the boundary to space - the Kármán line - of a hypothetical methane atmosphere on Mars with a surface pressure of 1 atm. To do this, we derived expressions for the particle density where the lift of a plane can no longer increase, and compared it to the particle density on Mars as a function of height through the Law of Atmospheres. This gives a Kármán line at ∼ 210 km.
