Mars between ice ages and how life began

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -"Mars is not a dead planet -it undergoes climate changes that are even more pronounced than on Earth,” according to James Head, a planetary geologist at Brown University. The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. See article.
g Life - How life began - this problem really permeates much of humankind, societies and cultures past and present. Some have evoked a supreme being to explain the origin of life; others look to the scientific method to provide answers. Regardless of the position, there have been at least two extremely exciting discoveries or reports that really change the nature of the game. See article.
g Message -Just exactly how does SETI work? Here’s a primer.
g Aftermath - Understanding the public’s current thoughts on what will happen once humanity discovers extraterrestrial intelligence is a vital part of any objective discussion in which we attempt to predict and prepare for the aftermath. Here’s one person’s view. Note the mix of popular mythology (UFOs) and an almost spiritual notion that the aliens will help us or make our lives better in some ways, as if they were angels descended from the sky. A thought: Is this an indication that if the aliens are technologically superior, we’ll readily accept their ways and let it supplant our own culture?

Honoring the Past, Inspiring the Future
