Exobiology Extant Life Surveyor, also called EELS[1] is a vehicle designed to explore locations such as lunar lava tubes,[1][2] Mars's polar caps, Earth's ice sheets, and the primary target being Enceladus's oceans.[3][4]
It uses multiple segments containing actuation, propulsion, power and, communication electronics.[4] The segments use corkscrews to move across the ground.[1] These corkscrews can act as propellers while underwater.[4]
As of 11 May 2023[update], the current version (1.0) weighs approximately 100 kg (220 lb), and is 4 m (13 ft) or 10 segments long. EELS has no scientific instruments, uses stereo cameras and Lidar, and it uses a tether for power and communications.[1]
