Watch this: prototype NASA robot prowls the underside of frozen lakes, oceans

It’s a rough life for a space robot. It’s cold, dark, and there is no promise of a return trip back to Earth. There are also far off moons like Jupiter’s Europa, which are believed to have vast oceans underneath immense layers of ice, and that need exploring. How exactly to navigate those oceans with a remote-controlled robot may be the next step in understanding their makeup, which is just what scientists at NASA’s Jet Propulsion Laboratory are hoping for with a robot called Buoyant Rover for Under-Ice Exploration, or BRUIE. The device, which has been chronicled by National Geographic, stays afloat to give its metal tires a grip on the underside of any ice while its onboard sensors take measurements and send that information back to…
