Astrobiological expedition to Mars, why we don’t have to go there to find life and building multiple space stations

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 - The possibility that life may once have evolved on Mars is strongly linked to the availability of liquid water over long time periods. So what criteria would make a good site for an astrobiological expedition on that world? See
g Cosmicus -NASA is spending billions of dollars to search for life on Mars, the most Earth-like of our sister planets. But we may not need to go all the way to Mars to find another sample of life, says one astrobiologist. It could be lurking under our very noses. See
g Message -Quote of the Day: “Wow!” — Note scribbled on edge of printout indicating the Big Ear Telescope had picked up an extraterrestrial message
g Cosmicus -From the economic point of view, building orbital accommodation has the great attraction that it will provide a large-scale commercial outlet for the know-how developed with the US space station Skylab that operated from 1973-74, the two Russian stations Salyut and Mir, and the International Space Station being developed in the late 1990s. Many tens of billions have been and are being spent on these - but only one of each is ever built! So none of the manufacturers can make any money, and taxpayers have to pay for it all - but they never get to go! A truly crazy "lose-lose" situation! See
