Mars’ underground water reservoirs and looking for ETI with space-based platforms

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - By discovering the first double star where a pulsating Cepheid variable and another star pass in front of one another, an international team of astronomers has solved a decades-old mystery. The rare alignment of the orbits of the two stars in the double star system has allowed a measurement of the Cepheid mass with unprecedented accuracy. The new result shows that the prediction from stellar pulsation theory is spot on, while the prediction from stellar evolution theory is at odds with the new observations. See article.
g Abodes - An international research team led by the Planetary Science Institute has found evidence for reservoirs of liquid water on Mars at shallow crustal depths of as little as tens of meters. See article.
g Life - Giant pterosaurs - ancient reptiles that flew over the heads of dinosaurs - were at their best in gentle tropical breezes, soaring over hillsides and coastlines or floating over land and sea on thermally driven air currents, according to new research. See article.
g Message - The venerable Planetary Society hopes to take the search for extraterrestrial life to the stars with space-based platforms. See article.
g Cosmicus - NASA’s IceBite team is in Antarctica this month testing a new drill built by Honeybee Robotics for use on a possible future mission to Mars. In this blog entry, Kris Zacny writes about the first field tests of the Icebreaker drill. See article.
g Aftermath - Would ET vote? What affect will ET’s political philosophy have on ours once contact is made? See article. This article is from 2002.
