Thick or Thin Ice Shell on Europa?
http://photojournal.jpl.nasa.gov/catalog/PIA10131 Europa Tide Movie http://photojournal.jpl.nasa.gov/catalog/PIA10149 I'm not sure that there is any new science involved. Seems to me like some nice eye candy for the purpose of getting Europa into the collective consciousness before the next flagship is chosen. |

sorry to disappoint you thin-skinned, er i mean thin-shelled people. europas shell is thick, at least 10 more likely 20 km.
the smoking gun is the topography. there are places with 1 kilometer of relief in very short distances. one such scarp has a slope of around 30 degrees. a shell only a few kilometers thick simply cant generate or support such a large topographic height.
