NASA / ESA found a bacteria that lives in 'clean rooms' in space craft and space stations, feeding off the scattered remains of the less resistant bacteria.[0] the air is stringently filtered, the floors are cleansed with certified cleaning agents, and surfaces are wiped with alcohol and hydrogen peroxide, then heated to temperatures high enough to kill almost any living thing. Basically bacteria will evolve to survive in virtually whatever hellish environment you want to come up with. http://www.scientificamerican.com/article.cfm?id=bacteria-discovered-spacecraft-clean-rooms http://www.scientificamerican.com/article.cfm?id=bacteria-di...
