Finding life in our own solar system and polar dinosaurs

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 - Daniel P. Glavin, an astrobiologist at NASA's Goddard Space Flight Center, says the possibility of extraterrestrial life in our solar system is not limited to Mars; other "habitable" worlds might exist including the icy Moons of Jupiter and Saturn, known as Europa and Enceladus. The challenge for scientists and engineers in the next couple of decades, he says, will be to design miniaturized instruments and technologies capable of detecting the signatures of life in our own solar system and beyond. See article.
g Life - Large, carnivorous dinosaurs roamed southern Australia 115 million years ago, when the continent was joined to the Antarctica, and were padded with body fat to survive temperatures as low as minus 30 degrees Celsius. See article.
g Cosmicus - NASA's Spirit rover is on slippery ground. The rover's five working wheels have been slipping in soft soil, causing them to sink into the ground. It may be weeks before Spirit attempts to drive again, but in the meantime the rover will use its scientific instruments to study the properties of the troublesome soil. See article.
