Water may exist in Martain caverns

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Researchers have found evidence that water from catastrophic flood discharges 2 billion years ago may have been captured by extensive cavern systems on Mars. The findings could have implications in understanding the potential for life on ancient Mars. See article.
g Message - Book alert: Scour your used bookstore shelves for "Life Beyond Earth," by Timothy Ferris. Rock-solid science writer Ferris has covered this ground before. In the two-hour PBS documentary that he wrote and narrated - which shares the title, text, and many of the images of this generously illustrated book - Ferris tackles two age-old questions about the potentially universal nature of life: Are we alone, and, if not, is anybody listening? See reviews.
g Cosmicus - Astronaut Don Pettit continues his diary from Expedition 31 on the International Space Station. In this installment he talks about dealing with reflected light in space photography and capturing images in the far infrared. See article.
