PICTURE SHOWS: Jupiter???s icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA's Galileo spacecraft in the late 1990s .... STORY COPY: A little robotic explorer designed to search for aliens in the icy waters of other planets will be tested this month (Nov). BRUIE, or the Buoyant Rover for Under-Ice Exploration, will be rolling into Antarctica to perform a gymnastic feat - driving upside down under sea ice. The robot is being developed for underwater exploration in extraterrestrial, icy waters by engineers at NASA's Jet Propulsion Laboratory in Pasadena, California. It will spend the next month testing its endurance at Australia's Casey research station in Antarctica, in preparation for a mission that could one day search for life in ocean worlds beyond Earth. There are moons throughout the solar system believed to be covered in deep oceans hidden beneath thick, frozen surfaces. Scientists like Kevin Hand, JPL lead scientist on the BRUIE project, believe that these lunar oceans, such as those on Jupiter's moon Europa and Saturn's moon Enceladus, may be the best places to look for life in our solar system. But first, they'll need a tough aquatic explorer capable of navigating solo through an alien ocean locked under ice sheets that could be 6 to 12 miles (10 to 19 kilometers) thick. "The ice shells covering these distant oceans serve as a window into the oceans below, and the chemistry of the ice could help feed life within those oceans. Here on Earth, the ice covering our polar oceans serves a similar role, and our team is particularly interested in what is happening where the water meets the ice," said Hand. The Antarctic waters are the closest Earth analog to the seas of an icy moon, which makes them an ideal testing ground for BRUIE technology. Three feet (1 meter) long and equipped with two wheels to roll along beneath the ice, the buoyant rover can take images and collect data on the important regi
