The colonization of planets is a pretty good idea, but it must have its challenges; thus, we don’t have enough information about its environment and different temperature and pressure can make the matter exist in different .
So we will detect the material normally; hence, the techniques of detecting materials is are known, but we will give a chance to determine which the state the matter will according to its phase diagram.
On Earth as we have oceans flatten surface and we calculate the perspective to that surface, but if we looked at mars or other plants don’t have that reference, so they toke the minimum pressure which can exists in liquid and calculate the altitude by the any pressure-height equation.
