Europa has long been a prime target in the search for extraterrestrial biology because scientists suspect it harbors a subsurface ocean beneath its icy crust, potentially teeming with microbial life. But the robotâpacked with radiation shielding, cutting edge software, and ice drilling appendagesâwonât be going anywhere anytime soon. In a recent paper in Science Robotics , engineers at NASAâs Jet Propulsion Laboratory JPL outlined the design and testing of what was once the Europa...
