In the hunt for extraterrestrial life, one of the best places to look is Mars. Science fiction authors have been imagining life on Mars for generations, and scientists have been looking for signs of life on the red planet for decades.

It's always cold, there's almost no liquid water, and ultraviolet light constantly bombards the surface of the planet. Just based on those facts alone, the case for life, at least on anything that's currently alive, does not look good. But there's another factor that makes life on the surface of Mars next to impossible: perchlorates.
