This Robot’s Journey to an Icy Alien Moon Starts Beneath Antarctica
Near a nice, big hole in the ice and beneath the stone gray, midday Antarctic summer skies, six Adélie penguins stared at six men toiling with tools. The chasm in the ice might have been an inviting entry to the krill-rich waters below. None of the members of the tuxedoed recon party dove into the hole, a square about six feet across. The risk of leopard seals was just too great.
But had they leapt in, the penguins would have discovered not a seal, but a robot.
