Bad news for whom?
You presume then that everyone here would want to discover indigenous Martian life?
I would imagine that most of those (who've taken the time to consider the prospect) with Gerry O'Neil like designs on the solar system wouldn't like the existance of exotic microbes any more than spotted owls.
Now then, the idea that Martian life is dependent on a long lived warm hydrosphere is phooey. Read the book "The Deep Hot Biosphere" by Thomas Gold if you still think so.
