Illustration of an astronaut leaving their Mars rover vehicle to explore the planet's surface. An explorer steps out of the airlock and on to the porch of a martian motorhome to begin several hours of extravehicular activity. The explorer's specialized suit is revealing of the extreme inhospitably of the martian environment to human life. Without the suit, not only would a human immediately suffer from Mars' lack of breathable oxygen and extreme cold, but the very thin atmosphere would result in all the fluids in the explorer's body quickly coming to a boil at room temperature. That alone would cause immediate and catastrophic organ failure, unconsciousness, and imminent death. Thereafter the flesh would quickly desiccate and any liquids that had not boiled away would solidify, leaving a freeze09/14/2009dried corpse far more impervious to decay than any Earth09/14/2009bound mummy.
