On the surface of Jupiter's moon Europa, linear surface features appear on a manifold of scales and directions. The general understanding is that these features develop out of cracks in Europa's ice shell. This is interesting for habitability because these cracks might provide a connection from Europa's liquid water ocean to the icy surface. In this study, we apply a statistical model to smooth the direction of observed linear features to see if we can find a connection with Europa's tidal stress field. Especially younger lineaments might show a different correlation than older ones. The current status of the work is presented.
