Dry Antarctica’s water and last shuttle flights announced

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 Stars - What is the habitable zone for the nearby star LHS 288?
g Abodes -NASA says the soil appears similar to that found in Antarctica's dry upper valleys and the salts it contains are another indication of the presence of water. See article.
g Message - The Search for Extraterrestrial Artifacts, or SETA, is about delineating between the artificial and the real. In the case of radio detection from other stellar systems, the artificial is what is labeled the real signal that intelligent communications are on-air. See article. Note: This article is a couple of years old.
g Cosmicus -NASA has announced the dates of its last shuttle flights. See article.
g Aftermath - Among scientists involved in the Search for Extraterrestrial Intelligence, it’s quite common to be focused on the future, ever mindful that it could take years, or even decades, to find a signal from otherworldly intelligence. But if historian Steve Dick has his way, astronomers will also turn their attention toward the past as they search for life beyond Earth — to discover the aftereffects of contact between two intelligent cultures. See article. Note: This article is from 2003.
