BRUIE  (Buoyant Rover for Under-Ice Exploration) is an underwater rover prototype by NASA's Jet Propulsion Laboratory. The rover began testing in the Arctic in 2015 and it is meant to eventually explore the interior ocean of water worlds in the Solar System. BRUIE is buoyant and uses its two wheels to roll along beneath the ice and look for life.
