Exobiology Extant Life Surveyor

Exobiology Extant Life Surveyor, also called EELS is a vehicle designed to explore locations such as lunar lava tubes, Mars's polar caps, Earth's ice sheets, and the primary target being Enceladus's oceans.

It uses multiple segments containing actuation, propulsion, power and, communication electronics. The segments use corkscrews to move across the ground. These corkscrews can act as propellers while underwater.

, the current version (1.0) weighs approximately 100 kg, and is 4 m or 10 segments long. EELS has no scientific instruments, uses stereo cameras and Lidar, and it uses a tether for power and communications.
