If we are looking for non-corporeal life forms, I think we may be relying
upon science fiction a little too much. It is true we don't know every thing
about nature but one of the necessary properties of living things is that it
must use energy and release energy (metabolize). It is hard to

Any idea how much fuel it consumed during those 18,000 hrs? That information
wasn't given.

Inchworm is interesting but as one drills
through solid ice or snow the material pushed back behind the device will never
be as compact as it was in front of the drill, therefore it appears (to me)
that the drill mechanism will get jammed by its own drilling residue.

There are several sources of rocky material on Europa. I wouldn't hazard a

The steam propelled torpedoes JH Byrne mentioned were powered by
concentrated hydrogen peroxide. H2O2 contains a lot of energy that might be
more useful in the submarine that navigates in the open water beneath the

Using a chemical reaction to melt through miles of ice won't work. The

will require thousands of tons or reactants, even lithium!

A lot of good questions and comments have been given regarding the thickenss
of Europan Ice and how to penetrate it.
Here are some ideas researchers could take to determine ice thickness.
(Maybe this is not a new idea.) When we were first interested in going to
