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. |

Getting at the ice shell thickness has been a real problem. All our evidence is circumstantial. But there are mountains a kilometer
high and basins a kilometer deep. the surface is warped and the craters need to get very large before they start to penetrate near the bottom. all these things point to a thicker ice shell, likely a minimum of 10 km, possibly as much as 20 km. -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX
