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. |

Really is a conundrum... to me. I just wonder how you get enough energy from warm (hot) water plumes in the underlying ocean to penetrate through kilometers of steel hard ice. Yet the topography demands a thick ice shell.
Cool problem |

agreed. the new model and even the diapir model rely on warm ice from the base of the shell rising upward in a dome, like porridge boiling on a stove. water plumes melting through this thick ice is very difficult indeed, but doing it within the shell, thats easy(ier)
