Life on Mars after all...?

''The lander confirmed the ice was there. It also analyzed soil samples that may imply a wetter Mars in the past
During the day, the Martian air was its most humid with 2 Pascals of water vapor pressure, which is 100 to 1000 times less than on Earth. Each night, beginning at 8:00 p.m. (local solar time) the water vapor would begin to disappear, reaching a low at around 2:00 a.m. of around one percent of its daytime value.
Sometimes the films build up into water droplets (dew) or ice crystals (frost). But on Mars the thin films of water never become solid or truly liquid. Zent calls these Martian films "unfrozen water."
