Gilbert V. Levin commentary on the book MARS: THE LIVING PLANET

[chrisdahms]

I think the new Navarro-Gonzalez/ McKay paper is a turning point. The perchlorate finding goes a long way towards explaining the Viking life-detection/organics results.

Allowing liquid water to persist at the surface of Mars, destroying evidence of organics when heated, also acting as a food source for micro-organisms. Thanks for uploading these interesting videos.
