Many European Space Agency scientists were there, and I thought afterwards I may get some backlash, but they took it surprisingly well.<\/p>\n<p class=\"sc-77igqf-0 fnnahv\">The science concept in this case is that salts, and organisms with the help of the salts, can pull water directly from the atmosphere. There\u2019s also an effect where, as water is removed, there\u2019s a sort of delay \u2014 a hysteresis \u2014 because the system resists crystallization. This means water can remain in a salt longer than expected, which is crucial because it raises the water activity on a microscopic level, making it accessible to microbes. Life is very good at taking advantage of these physical or chemical effects. There are plenty of examples in biology, which is very good at using these kinds of effects \u2014 I\u2019d nearly call them tricks because they\u2019re using this kind of quirky physics or chemistry.<\/p>\n<p class=\"sc-77igqf-0 fnnahv\">Of course, I can\u2019t say there\u2019s definitely an organism on Mars exploiting these effects. But Mars, almost 4 billion years ago, was so much like Earth, with abundant water. As it became drier, moving toward its current desert state, these are the kinds of adaptations I\u2019d expect any remaining life to develop.<\/p>\n<\/blockquote>\n<p class=\"sc-77igqf-0 fnnahv\">No, these microbes aren\u2019t the aliens from \u201cSigns.\u201d They wouldn\u2019t be allergic to water, just sensitive to the liquid.
