An expedition that will help NASA search for life in deep space launched today – not with a rocket’s roar, but with a gentle splash into the deep Pacific Ocean. The project will use underwater robots to explore the environment around a deep-sea volcano off the coast of Hawaii that has similar conditions to what may exist on Saturn’s moon Enceladus.
