How can scientists know what can and can't survive in outer space if they have never studied how all of Earth's different life-forms react to being in outer space? There may be things on this planet that could thrive up there like moss, lichens, bacteria, viruses, cockroaches, Hostess Twinkies...
There is a theory called panspermia that speculates that life can travel from one planet to the next slowly spreading throughout the universe. If it is true (and I believe it is) than life could theoretically exist on all of the planets to a certain extent. It may only be single-celled organisms and it may be frozen solid as a rock but it could still exist. All it would need is to find a planet where conditions are ideal to support complex life-forms and another Earth could be forming. I personally think there are millions of planets out there similar to the Earth...we just haven't found them yet. That doesn't mean that life from those planets hasn't found us though.

I was hoping the article would mention Tardigrades,,,and it did. They're interesting little critters.
