You'd think so, but it looks like some sort of liquid is there..

You would think it was too cold, and also too low of pressure (even if small spots are hot enough for whatever reason the liquid would turn to vapor) But extremely salty water (perhaps with a very special combination of the right salts), that's not directly exposed to the atmosphere (perhaps slightly underground) could perhaps exist. Or perhaps brine ice could have been heated by the landing and become liquid (before freezing out and or evaporating). Following the link to the article I see that the salts are "perchlorate salts that greatly decrease the freezing temperature of water" not ordinary salt, and "Such brines are just 2-10 centimeters below the surface in the Antarctica Dry Valleys". So perhaps these brines on Mars where just below the surface and not fully exposed to the low pressure.
