Overview
JPL's snake-like concept for descending the geyser vents of Saturn's moon Enceladus and exploring lunar lava tubes, Martian polar caps and terrestrial ice sheets. Prototypes were tested on an ice rink in 2022, on the Athabasca Glacier in Alberta in 2022–2023 and in snow at a California ski resort in 2023. JPL lists the project as in development.
