Even outer space can't kill them...

No, that's not a line from a 1950s movie. It's a description of how hard it is to kill some bacteria. Sure, Lysol will probably do it, but experimenters took bacteria from English cliffs (still clinging to rock shards) and put them in experiment boxes on the outside of the International Space Station. Eighteen months later, heat, cold, radiation, and vacuum had done...nothing to them. Wherever we go in the universe, it seems, we will take out bugs with us.
