NASA remote pilots an untethered rover under Alaska‘s ice, in a first-time success. An unmanned vehicle that may be explore the icy oceans of Jupiter‘s moon Europa.   Watch the video…

It’s a milestone in the quest to develop an unmanned vehicle that could one day plumb the icy reaches of moon Europa.

The rover uses a two-wheeled design with a flexible dragging tail, enabling it to fit into a 10-inch diameter ice borehole. The sealed air-filled cylindrical body, along with closed-cell foam inside of cone-shaped wheels, provides buoyancy force to enable roving along the underside of the ice.
