Re: Hunt for life on Mars dealt another blow
What stops the know H2O permafrost acting exactly like you suggest the CO2 could?
Even if it turns out to be liquid water at work here is life likely to form around these short term liquid water events? Wouldn't it be sensible to seek life in places where liquid water could be a stable form?
If your CO2 interpretation is correct...I don't see how this is anykind of a death blow for the search for life on Mars. It just narrows the locations to look.
