Using pollution to find ETI and how instruments for future Mars missions are tested on Earth

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 - A dusty red planet and an icy moon of Jupiter may hold the best hopes for scientists trying to track down extraterrestrial life, at least in this solar system. See article.
g Intelligence - Scientists have proposed what seems like an obvious solution to finding life on other planets—look for pollution similar to that found on Earth. Light or air pollution would be a dead giveaway to life on another planet, according to a study to appear in the journal Astrobiology. See article.
g Message - A picture is worth a thousand words, especially if you're trying to get your point across to someone who doesn't speak your language. At least that has been the assumption of many proposals for communicating with extraterrestrials; in a recent image beamed into outer space, the world’s largest radio telescope in Arecibo, Puerto Rico, images of a human being, the double helix of DNA and our solar system were included. But would pictures necessarily be understood at interstellar distances? See article. Note: This article is from 2000.
g Cosmicus - In this blog entry, Juan Diego Rodriguez Blanco from the AMASE 2009 team discusses how instruments for future Mars missions are tested on Earth. This year, equipment for ESA's ExoMars mission and NASA's Mars Science Laboratory were put through the ropes on the Arctic island of Svalbard. See article.
g Aftermath - High-tech telescopes on the ground and in space that perform daunting astronomical peep shows in a search for Earth-like worlds aim to answer one of humankind's most monumental questions: "Are we alone?" There is on-going deliberation relating to the societal, philosophical and religious fallout that stems from resolving such a stellar inquiry. See article.
