   I'm sure it's been tried -- there's been radar work done on the Galilean   
   satellites -- but I don't recall ever seeing any results (not that it's an   
   area I follow much).  For a guess, you just don't see very much -- radar   
   astronomy is primarily for surfaces, you don't get major reflections from   
   clouds.

   It was understood before arrival, from ground and Hubble observations,   
   that the probe entry point had a high probability of being abnormal, by   
   sheer bad luck of what atmospheric features happened to be there at the   
   time.  But nobody knows for sure *how* abnormal it was.
