Mapping interstellar boundary at the edge of our solar system and primitive Earth mantle reservoir

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 - NASA's IBEX spacecraft has mapped the interstellar boundary at the edge of our solar system. IBEX has also provided measurements of the Earth's magnetosphere, which maintains our planet's habitability by protecting the biosphere from harmful radiation. See article.
g Abodes - Researchers have found a primitive Earth mantle reservoir on Baffin Island in the Canadian Arctic. The discovery will help researchers understand the composition of the original, early Earth. See article.
g Life - Scientists plan to develop and operate airborne science platforms to carry biological sampling devices and retrieve organisms, such as microbes, algal spores, viruses, and fungi, and other evidence of life from lower atmosphere to the upper atmosphere, or more than 78 miles above the surface of Earth. See article.
g Message - Of the many "maybes" that SETI has turned up in its four-decade history, none is better known than the one that was discovered in August, 1977, in Columbus, Ohio. The famous Wow signal was found as part of a long-running sky survey conducted with Ohio State University’s "Big Ear" radio telescope. See article. This article is from 2002.
g Cosmicus - The U.S. Army's desire to deploy swarms of tiny satellites for various tactical missions is one of the reasons it began development two years ago of what would be the United States' smallest orbital launch vehicle, designed to put payloads of about 20 kilograms into space, government and industry officials said. See article.
g Aftermath - To create interstellar messages that have a realistic chance of being understood across interstellar distances, we need to identify some information shared by humans and extraterrestrials. We need to identify a foundation for establishing a universal language that will let us bridge the gap between our world and theirs, all without the convenience of face-to-face contact. See article. This article is from 2002.
