Hi All Following this Physorg article... http://www.physorg.com/news184915200.html" [Broken] ...here's the webpage of the Professor's Directed Panspermia Society... "[URL [Broken] Society for Life in Space (SOLIS)[/URL] ...in which he describes a program for propagating microbes throughout the Galaxy, as a near-term way of spreading our kind of Life far and wide. Altruistic in the extreme? Makes me wonder just how much of a role panspermia has had in our Solar System too. Is our Last Universal Common Ancestor from somewhere other than Planet Earth? Did Life begin here and spread wherever it could in the early Solar System? According to the current best guesses there were four probably reachable habitats - wet early Venus, early Earth, warm early Mars and warm early Titan. Titan slowly froze, Mars lost its thicker atmosphere, and Venus lost its oceans - only Earth remained within Life's ability to 'govern', though the Great Oxidation event almost froze it solid, the Sulfate era almost choked it and various other catastrophes have threatened Life here from time to time. Life wasn't meant to be easy!
