Well, maybe?

Rather, in the researchers' model, cosmic rays provide the chemical drive necessary to convert molecular hydrogen and carbon dioxide into water and other products. To keep the system stirred up, the authors invoke the tidal forces exerted by the planet on its moon as a source of heat—and assuming that carbon dioxide accounts for 90% of the moon's atmosphere, the resulting greenhouse effect would effectively retain a large part of the heat generated on the moon. Together, these energy sources would suffice to keep water in the liquid state.

Yes maybe. It’s not going to be every occasion that is sure.

Wasn't there a planned NASA mission to crash a submarine probe through the frozen surface of one of the moon's of Jupiter?

One can only imagine what could lurk in those oceans.

Here you go.... Europa Clipper.
