In the absence of juvenile liquid water, condensation of water vapor to ice and subsequent melting of ice are the only means of producing liquid water on the martian surface. However, the evaporation rate is so high that the available heat sources cannot melt pure ice. Liquid water is therefore limited to concentrated solutions of strongly deliquescent salts.
在缺乏幼年液态水的情况下,水蒸气凝结成冰以及随后冰的融化是火星表面产生液态水的唯一途径。然而,蒸发率非常高,以至于可用的热源无法融化纯冰。因此,液态水仅限于强烈吸湿盐的浓缩溶液。
