What if you could send a robot to explore the hidden ocean beneath the icy surface of Saturn’s moon Enceladus? That’s the idea behind NASA’s EELS (Exobiology Extant Life Surveyor), a snake-like robot that can slither through narrow crevasses, grip on slippery surfaces, and sense its environment autonomously. EELS is designed to descend the vents on Enceladus that spew water and organic molecules into space, and look for signs of life in the ocean below. Watch this video to see how EELS works, and how it could revolutionize the search for alien life in our solar system.
