What is the likelihood of bacterial life on Mars infecting the earth if we ever get around to visiting Mars in person?"

    Another interesting possibility is that we may infect Mars. What if the astronauts get there, and some random bacteria is on their spacesuit? Or some other piece of equiptment for that matter? It 'd be like smallpox in the New World all over again. We could actually see life on Mars destroyed by our visit, before we ever actually get to see much of it.
