PR Preatmosphere Ethics Society Habitat Atmosphere Water Water is an essential component to the existence of life. We have detected evidences of ancient liquid water and glaciers on the surface of Mars. However, physical conditions and the atmosphere of Mars create a regime where liquid water is unstable. The parameter influences this problem is low atmospheric pressure and temperature.
Liquid water is only possible if the temperature and pressure are high enough.
Therefore, we may assume that the temperature and pressure have somewhat already increased. There are several ways to obtain water. On Mars today, water exists as ice or vapor. Water is now locked in the polar ice caps. Mars' polar caps are like Earth's North and South Pole.
