Frozen Water Found At Mars Mid Latitude And Science Society And The Search For Life In The Universe
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 - NASA's Mars Reconnaissance Orbiter has revealed frozen water hiding just below the surface of mid-latitude Mars. The spacecraft's observations were obtained from orbit after meteorites excavated fresh craters on the Red Planet. See article.
g MESSAGE - It's not easy to look for life somewhere other than Earth. First, scientists searching for life in space have to come up with a working definition of 'extraterrestrial life'. Next, they need to develop a strategy identifying places and methods for their search. To make matters more complicated, all of this has to be done without contaminating the search site with life from Earth or contaminating Earth with potential extraterrestrial life. See article.
g COSMICUS - The spacecraft MESSENGER is just a day or two days away from its third encounter with Mercury. See article.
g LEARNING - Book alert: A fair amount has been written in recent years about the emerging science of astrobiology: the search for life, intelligent or otherwise, on other worlds in this and other solar systems. Far less, though, has been written about the interplay of astrobiology and the sciences that constitute this multidisciplinary field with broader society-a factor that could become critical should astrobiologists one day discover evidence of life beyond Earth. That, and many other far-reaching issues associated with astrobiology, are tackled by University of Colorado scientist Bruce Jakosky in "Science, Society, and the Search for Life in the Universe". See review. Note: This review is from 2006.
g AFTERMATH - Quote of the Day: "Sometimes I think we're alone. Sometimes I think we're not. In either case, the thought is staggering." - Buckminster Fuller
