Hmmm...

Though related to my questions, it's not exactly what I was referring
to... I'm not familiar with Zubrin, but it sounds as if it's not really
something I want to get into a debate about. Your comment about
pathogens and manned flight returning from Mars poses a serious implication.

I was however unaware there was a "push" behind the panspermia and it's
relation to back contamination...

Regards,
Eric
