Mars has an average surface pressure of about 6 millibars https://youtu.be/RTbHC3aEsQk, compared with Earth’s 1013.25 millibars, which is close to the triple point pressure of water at roughly 6.1 millibars. Combined with low temperatures, this pressure means liquid water is generally unstable on the Martian surface, restricting its geology, climate, and the potential for life.
The thin Martian atmosphere strongly influences surface processes. Low pressure and cold temperatures suppress stable liquid water and limit cloud formation, leading to minimal precipitation. As a result, aeolian processes dominate, shaping broad plains.
On Earth, the atmosphere regulates global temperatures through the greenhouse effect and shields the surface from much of the Sun’s radiation and many high-energy particles. Mars, by contrast, has a weak atmosphere that offers limited protection, exposing the surface to elevated radiation levels that affect organic molecules.
