Mini-Subs Could One Day Ply the Seas Under Europa's Ice

Europa and Enceladus have become two of the most exciting places to search for life in the Solar System. We know that both worlds have liquid oceans underneath thick layers of ice. Assuming you could bore down through the ice, what's the best way to explore their oceans? Researchers have built an underwater autonomous vehicle that measures just 50 cm long. It's small enough to fit inside a melting probe and then deploy once it reaches the water. Scientists will test the vehicle under the ice in Antarctica, but one day, it could be deployed on icy worlds.
