EELS robot might help JPL look for life on watery worlds

> is designed to go places that have never been accessible to humans or robots before.

Cool on paper, but what about battery endurance, how long it will last? Assuming there are no solar panels like the ones on the rovers

> The liquid ocean beneath the frozen surface of Enceladus? EELS could tunnel its way there and look for evidence that the Saturnian moon might be hospitable to life.

Also, I am really interested to know how their radio waves will penetrate through all that and still have a proper feed/C2 link despite the distance, even if it is laggy?
