Re: Thoughts on Bio Contamination



Mars does have water ice which is the same as Earth's, it could be
possible for bacteria to remain dormant encased in the ice. In that
case, the only way for any Martian organism to make it to Earth and
survive, would be in the form of a Martian ice meteorite landing in a
frozen environment, say Antarctica. But, i'm not sure of the possibility
of ice surviving a trip through the atmosphere.

Simple. It's the same planet!!
Same atmosphere, mean temperature, mean precipitation, same hosts (in
the case of disease)same radiation,same weather, same nutrients in the
soil, and a long list of et cetera's. Mars has none of these in common
with the Earth. 
 
According to Zubrin, expecting Mars life to damage the Earth is less
likely than sharks out-competing lions on the Serengeti. It is not
possible.
