Named for the Ancient Greek god of the Underworld, the Hadal Zone is the pitch-black part of our oceans below 6,000 meters. Now, imagine a fleet of robots able to roam freely in the parts of the ocean that have been almost impossible for humans to reach, and bring back what they see: such as life forms that can survive with zero sunlight, very little nutrition, under pressure that could crush a car. OceanX’s research vessel, the Alucia, took engineers from Woods Hole Oceanographic Institution and NASA’s Jet Propulsion Laboratory to test a brand-new prototype that will one day explore these remote, unforgiving parts of our planet, and eventually, oceans throughout our solar system.
