Journey to an Alien Moon

Scientists are developing robots to probe the icy waters of Jupiter's moon Europa, in temperatures of minus 260 degrees and searing radiation. Expert Bill Stone and his team hope to test an autonomous underwater vehicle called Endurance; CGI animation helps envision how its descendant would fare on a real mission to Europa. Getting a robot through the ice and into the oceans of Europa will be an order of magnitude more difficult than anything Stone's team has done so far.
