Xeno biology???? If life ever began on Mars, I believe that it will still be there. The climate cannot have changed quickly enough to extinguish microbial life and it should thrive there not just cling on to existence.
I accept that the magnetite found in "martian fossils" could be a local adaptation of martian bacteria to localised magnetic anomalies and that these could coincide with methane emissions discovered recently. What I object to is the constant use of these principles (though I accept them, I do not believe them) to suggest that we cannot send a manned mission to Mars. The very idea that a martian microbe could be pathogenic when it would be clearly adapted to a cold dry environment is absurd. I would bet my life on Mars being sterile. Even if I turned out to be wrong, I'd go double or quits on any Martian vector being unable to attack a Terran organism kept in an environment akin to it's home (eg humans at room temp and pressure) Rob Mc --- On Wed, 5/5/10, E.P.
