A Salty, Martian Meteorite Offers Clues to Habitability
Life as we know it requires energy of some sort to survive and thrive. For plants, that source of energy is the Sun. But there are some microbes that can survive using energy from chemical reactions. Some of them even eat salts, such as perchlorates.
Perchlorate (ClO4-) is a highly oxidized form of chlorine. Perchlorate salts are found not only on Earth, but also on Mars. They’re highly toxic to humans but are useful for components such as rocket fuel.
"Space is big. Really big. You just won't believe how vastly, hugely, mind-boggingly big it is. I mean, you may think it's a long way down the street to the chemist, but that's just peanuts to space." - The Hitch-Hikers Guide to the Galaxy - Douglas Adams 1952 - 2001
