NASA's snake-like robot to search for life on Saturn's moon.

NASA's Jet Propulsion Laboratory is developing a snake-like robot called Exobiology Extant Life Surveyor (EELS) to explore internal terrain structures, assess whether organisms can live in those structures, and search for evidence of life on one of Saturn's moons, Enceladus. The robot is made up of multiple, identical segments that allow it to be self-propelled and uses rotating propulsion units that act as tracks, underwater propellers, and gripping mechanisms. The harsh conditions on Enceladus, including temperatures of 300 degrees Fahrenheit below zero, factored into the design of the robot.
