The exploration project is named Depthx after the robot, a deepwater explorer that NASA funded for $5 million.
This first mission proved that Depthx could find its way through underwater space, collect samples in unexplored areas, and navigate back.
Depthx could be part of future space probes to Europa, where scientists believe that deep cracks and holes in the ice offer a chance of finding extraterrestrial life.
