Mars' global volcanic upheavals and the day after contact

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 - New data from Mars indicates that the planet has undergone a series of global volcanic upheavals that spewed lava and water onto the surface. New clues about the geological history of Mars may help determine if the planet was once suitable for life. See article.
g Life - The first field surveys of the Rubeho Mountains in Tanzania revealed over 160 animal species -including a new species of frog and 11 endemic species, according to an article published in the African Journal of Ecology. The findings elevate the importance of protecting this biologically rich wilderness area and the broader Eastern Arc Mountain range from destructive activities underway such as clear-cutting for agriculture, logging and poaching. See article.
g Message - Here’s something neat albeit technical: A slide show presentation of "Spectrum Environment of the Allen Telescope Array." See article.
g Aftermath - Here’s a brief but interesting piece: “The Day After Contact: Forecasting Reactions to Extraterrestrial Contact.” Note: This article is from June 1999. See article.
