"Researchers at the University of Arkansas recently took a step toward answering a question for the ages: Is there life on Mars? Answer: they can't rule it out. Two recent publications suggest that life, in the form of ancient, simple organisms called methanogens, could survive the harsh conditions found near the surface of Mars, and deep in its soils. Using methanogens to test for survivability is particularly relevant because scientists have detected their byproduct, methane, in the Martian atmosphere. On Earth, methane is strongly associated with organic matter, though there are non-organic sources of the gas, including volcanic eruptions. Scientists aren't yet sure what the presence of Martian methane means. But one possibility is that tenacious life flourishes on Mars despite the rocky soil, thin atmosphere and scarcity of liquid water…"

What about tardigrades (water bears Tardigrades are immensely more complex creatures then any bacteria.
I have no doubt there can be any number of living organisms living on Mars. Mars is not more inhospitable then plenty of places on earth. The question is did life even start on Mars? If it did then there is probably something living there now.
If life didn't start on Mars then naturally there isn't any life there now. |

I keep thinking of the brown goo at the beginning of Species 2, and how it got outside of containment and into the main cabin of the shuttle coming back from Mars … YouTube link Dan |
