Exploring Ocean Worlds with Robots.
The search for life beyond Earth needs robots. But to explore distant ocean worlds like Jupiter's moon Europa, we’ll need a new set of tools to drill through ice, reach faraway samples and cross difficult terrain. NASA’s Jet Propulsion Laboratory recently finished a series of prototypes that might make that exploration a little easier.
Those systems would face a variety of challenging environments. Temperatures can reach hundreds of degrees below freezing. Rover wheels might cross ice that behaves like sand. On Europa, surfaces are bathed in radiation.
