Ice-covered lakes in Antarctica are no exception. But to study the microbes that hang out down under the ice, researchers have to do some risky diving. Dale Andersen is a pioneer of the technique. Living Above the Tree Line, Inside a Rock http://www.astrobio.net/news/article1348.html Are there places on Earth devoid of life? One of the most barren spots on the planet is above the tree line, where glaciers strip the land of nutrients and life. But enough dissolved organics may flow in melting streams to point to microbial life where no life was previously imagined. Preparing for Deep Impact http://www.astrobio.net/news/article1347.html The Deep Impact mission will deploy a probe that essentially will collide with the nucleus of comet Tempel 1 at approximately 37,000 kph (23,000 mph). The probe is designed to excavate a crater in the comet about the size of the Roman Coliseum, while a nearby spacecraft will be taking pictures and data continuously. Dione and Titan: Zooming Into View http://www.astrobio.net/news/article1346.html The close approach of the Cassini probe, now flying by Saturn's moons, Dione and Titan, reveals a complex atmosphere with clouds hovering over what may prove next month to be continents and even oil-rich oceans.
